In facilities with high volumes of foot traffic, the constant opening and closing of doors not only lets in chilly air but can cause heating problems for the entire building. Cold drafts bring the temperatures down, so while main rooms benefit from the warmth of the building’s primary heating system, many other areas are left to deal with the arctic side effects. Vestibules, lobbies, entrance ways and hallways are frequently populated, so it’s imperative that facilities hunker down and counteract the cold drafts left behind by those entering and leaving buildings.  Opt for electric ceiling heaters To help neutralize these blustery winds, facilities should consider fan-forced wall heaters that provide continuous comfort through optimized airflow. Such units are ideal for entryways and other spaces where short bursts of heat are needed – providing a tremendous advantage over gentle heating sources that may not be powerful enough to provide the desired amount of warmth. However, if wall and floor space is minimal, facilities can instead opt for electric ceiling heaters. Mounted flat or recessed to the ceiling, these heaters are ideal not only for entryways but also in conference rooms, waiting areas, bathrooms and lobbies. No matter the case, both products move heated air with a fan to quickly heat the room from the wall or ceiling. Once the heater turns on, air is moved over a heating element and circulated into the space, making certain that residents are met with warmth and comfort from the time they enter the building until they leave.  Specialized Performance Whether it’s through vents, unsealed windows or cracks and crevices in the building’s foundation, cold air will creep into facilities any way it can. This cool air can make indoor temperatures uncomfortable for occupants and reduce the overall heating efficiency of the facility. Specialized heating units are designed to stop drafts in their tracks before they spread throughout a building.  Fan-forced wall and ceiling heaters with an automatic delay feature eliminate cold drafts on start-up and discharge residual heat from the heater body during shut down, helping attack drafts at their source, making the best use of available heat and prolonging the life of the heater. To maintain desirable comfort levels, facilities should consider fan-forced wall or ceiling heaters equipped with integrated thermostats or BMS connections for easy adjustment of room temperatures.  A hotel’s vestibule, for example, may experience high amounts of foot traffic during check-in and check-out hours. Because less people are coming and going outside of these times, the adjustable thermostat feature allows facilities to alter their heating output needs to ensure heat is not misused and temperatures remain comfortable. For commercial fan-forced wall heaters with striking designs and contemporary looks, Berko® and QMark® offer units to match any room’s décor while supplying an appropriate amount of warmth no matter the time of year.  Safety First Safety and style go hand-in-hand. While selecting a heater that fits a building’s aesthetic is important, opting for a high-quality product that protects against common safety risks should be a top-of-mind priority. Fan-forced wall or ceiling heaters are built with easily accessible power on/off switches for added safety during maintenance. Tamper-proof plugs for thermostat holes prevent unwanted changes to the temperature and keep children and pets from getting into places they shouldn’t.  All fan-forced units also come with thermal overheat protectors that disconnect power in the event of accidental dust or debris blockages to mitigate risk of injury. Additionally, heaters that include permanently lubricated and enclosed fan motors are shown to have longer lives, require less maintenance and gently administer heat throughout a space. Keep in mind that some heaters are noisier than others, so make sure to choose one powerful enough to negate drafts but quiet enough to prevent disturbances from interrupting daily activities.  Maintaining Warmth and Comfort Drafts bring cold air and a lasting chill into heated spaces every time a door opens, especially during the colder months. To offset the frigidness, consider installing a fan-forced wall or ceiling heater to regain suitable levels of warmth and comfort for all building occupants. Berko and QMark’s commercial fan-forced wall and ceiling heaters provide the strongest, safest sources of heat for those chilly spaces.

As builders and contractors strive to meet ever-higher energy efficiency standards, airtight construction has become the new norm. While tighter envelopes cut energy waste, they also reduce outdoor airflow, creating new challenges for indoor air quality (IAQ) and occupant comfort. In response, Energy Recovery Ventilators (ERVs) have quickly moved to the forefront as an essential solution. Industry professionals often underestimate the capabilities and advancements of today’s ERV systems, despite their increasing importance in both residential and commercial applications. How ERVs Enhance High-Performance Builds Unlike basic exhaust fans, ERVs are built to provide consistent, balanced ventilation in high-performance buildings. They work by exchanging stale indoor air with filtered outdoor air, using a heat-exchange core to transfer both temperature and humidity. This process tempers incoming air, helping to ensure that what enters the living space is close to ideal conditions, regardless of the outdoor climate. ERVs contribute to lower energy bills, longer gear life, and more even comfort throughout the home In practice, this means that during winter, ERVs can pre-warm and humidify cold, dry air before it enters, reducing both discomfort and energy demand. In summer, the system pre-cools and dehumidifies incoming air, maintaining comfortable conditions and reducing air-conditioner system strain. By offloading some of the work from primary HVAC systems, ERVs contribute to lower energy bills, longer equipment life, and more consistent comfort throughout the home. From Code Compliance to Real-World Applications As building codes and standards such as ASHRAE 62.2 and Title 24 become stricter and evolve nationwide, ERVs have played a critical role in helping projects achieve code-mandated ventilation. Increasingly, these codes are moving beyond minimum airflow rates to address factors like energy recovery, humidity control, and occupant well-being, reflecting a broader understanding of indoor environmental quality. However, code compliance is only one part of the equation. ERVs have played a critical role in helping projects achieve code-mandated ventilation Today’s homeowners are more informed than ever about the health impacts of IAQ. They want ventilation systems that actively reduce allergens, pollutants, and excess humidity, helping to prevent issues like mold growth, respiratory irritation, and other health concerns. At the same time, they expect these systems to operate reliably throughout the year without driving up energy use, whether during heatwaves, deep freezes, or everyday seasonal shifts. This dual focus on health and efficiency is prompting a move away from lab-only performance metrics. Home building and construction industry professionals must seek ERVs that deliver on their promises in real-world conditions: fluctuating temperatures, high humidity, and varying occupancy levels. The latest generation of ERVs is designed and tested for precisely this kind of robust, year-round operation. Why ERVs Are Gaining Ground in Modern Construction The adoption of ERVs is accelerating in today’s construction market, and for good reason. Modern ERVs feature flexible, space-savings designs that make it easier than ever to integrate into both renovations and new builds – even when mechanical space is limited. This adaptability is a significant advantage for builders and contractors working within tight building constraints. ERVs deliver improved efficiency that leads to tangible drops in energy use and operating costs Beyond ease of installation, today’s ERVs deliver improved efficiency that leads to tangible reductions in energy use and operating costs. As energy codes become more stringent and utility bills climb, products that support energy conservation without sacrificing comfort are in high demand. At the same time, a growing body of research and field data demonstrates the positive impact ERVs have on indoor air quality, reinforcing their value in promoting occupant health and well-being alongside comfort. The future of ERVs isn’t just about efficiency, it’s about health. Recent research, including findings from the National Institute of Environmental Health Sciences, underscores the urgency of addressing IAQ in modern airtight homes. Rising pollutant levels, excess humidity, and a proliferation of synthetic materials can create health risks ranging from respiratory issues to cognitive impacts. ERVs can play a crucial role in mitigating these risks by continuously removing contaminants and controlling humidity, all while optimizing building energy use. A New Generation of ERVs When evaluating next-generation ERVs, professionals should prioritize systems that perform reliably across diverse climates, integrate seamlessly with existing HVAC and building automation platforms, and streamline both installation and ongoing maintenance. ERVs should be designed to meet the rising demand for robust, climate-ready solutions. ERVs should be designed to meet the rising demand for robust, climate-ready solutions They must deliver dependable ventilation performance in extreme conditions, as well as feature adaptable ducting and intuitive controls that help simplify installation. ERVs must also evolve to meet the latest building codes and real-world expectations, supporting healthy, resilient homes without adding unnecessary complexity for builders or contractors. This evolution of product requirements reflects a wider movement in the industry toward ERVs that address real-world installation challenges and changing code requirements. Features such as minimal airflow loss under static pressure, advanced moisture management for humid climates, and compatibility with smart controls are becoming increasingly important. As more manufacturers prioritize these attributes, professionals now have greater flexibility to select ERVs, like the Panasonic Intelli-Balance Elite and Elite+ Series, that meet the unique demands of each project, ultimately supporting healthier and more energy-efficient indoor environments. A Call to Action for Building Pros As codes tighten and consumer expectations rise, integrating ERVs into every project is a smart, future-ready move. By specifying advanced, climate-adaptable solutions contractors and builders can deliver spaces that are not only energy efficient but also healthier and more resilient. The bottom line: ERVs are no longer a niche add-on. They are essential for the next generation of high-performance, healthy homes. Those who embrace this technology now will be best positioned to meet the evolving demands of the market and deliver lasting benefits for their clients.

The data center market has shown robust growth over the past five years, with significant increases in capacity and electricity usage. According to the International Energy Agency (IEA), global data center electricity consumption was approximately 460 TWh in 2022, and it is projected to rise to over 1,000 TWh by 2026. This growth is driven by the increasing demand for digital services and the expansion of artificial intelligence (AI) workloads. In 2025, the total capacity demand for data centers is expected to reach 82 gigawatts (GW), with AI workloads accounting for 44 GW and non-AI workloads for 38 GW. By 2030, this demand is projected to increase to 219 GW, with AI workloads making up 156 GW. This significant growth underscores the importance of sustainable practices in the data center industry. Alternative Off-Grid Power Sources To meet the growing energy demands, data centers are increasingly turning to alternative off-grid power sources. These include solar power, wind turbines, micro-hydro power, and biogas generators. These renewable energy sources not only reduce the carbon footprint of data centers but also enhance their resilience by providing reliable power in remote locations.  Green hydrogen, produced by electrolysis using renewable energy, also offers a sustainable alternative to traditional cooling methods, with the potential to significantly reduce greenhouse gas emissions. Continued Compute Growth and Liquid Cooling Nvidia's use of direct-to-chip liquid cooling and closed-loop systems has shown a 300x improvement The rapid growth in compute power, particularly with the introduction of platforms like Nvidia's NVL-576 600 kW, has significant implications for data center cooling.  This platform, designed for high-performance AI workloads, requires advanced cooling solutions to manage the heat generated by such dense compute environments. Nvidia's use of direct-to-chip liquid cooling and closed-loop systems has shown a 300x improvement in cooling efficiency. Google's fifth-generation cooling distribution unit (CDU), known as Project Deschutes, is another example of innovation in this space. This CDU sidecar power rack supports up to 1 MW per rack, leveraging high-voltage DC power distribution to enhance efficiency and cooling capacity. Energy-Efficient Cooling Technologies Energy-efficient cooling technologies are critical for the sustainable operation of data centers. Some of the most promising technologies include: Direct-to-Chip Liquid Cooling: This method involves applying liquid coolants directly to the processors, providing superior heat dissipation and enabling servers to operate at optimal performance levels. Hybrid Rear-Door Heat Exchangers: These systems combine air and liquid cooling to manage heat more efficiently, particularly in high-density rack environments. Heat Reuse The elevated temperatures made by liquid cooling can also be harnessed in industrial processes Liquid cooling provides an additional opportunity to reduce energy consumption while enabling data centers to become contributors to community energy systems. Unlike traditional air cooling, which disperses heat into the atmosphere, liquid cooling captures heat more effectively, allowing the heat to be repurposed for the heating needs of nearby residential or commercial buildings. Heat pumps can be employed to raise the temperature of the excess heat to the temperature required by heating systems, resulting in greater energy efficiency. The elevated temperatures produced by liquid cooling can also be harnessed in industrial processes that require specific heat levels, such as pasteurization, drying or chemical processing. By utilizing this heat, industries can reduce their reliance on external energy sources, which in turn lowers operational costs and emissions. However, most areas in the U.S. lack the infrastructure to support district heating. Significant investment is required to develop the infrastructure needed to transport and utilize the heat, such as pipelines for district heating or retrofitting industrial processes. Depending on the region, there may also be legal or regulatory barriers to overcome. Policy and Community Engagement There is strong support for AI growth, with alliances involving companies like OpenAI and Meta Within the current U.S. administration, there is strong support for AI development, with partnerships involving companies like OpenAI and Meta. OpenAI, Meta, SoftBank and Oracle have joined forces for the Stargate Project, which aims to build AI data centers in the U.S. This project includes significant investments to create infrastructure that supports AI development. The Trump administration has identified 16 sites on federal land for the development of AI data centers. These centers are intended to provide the necessary processing capacity for machine learning, cloud storage, and AI systems. Heat reuse offers a powerful tool for sustainability and community engagement. By capturing and repurposing the waste heat, data centers can significantly reduce their environmental impact while providing tangible benefits to surrounding communities and industries. This approach not only supports decarbonization efforts but also fosters stronger ties between data centers and the communities they serve, creating a more sustainable and resilient future. Benefits and integration of data centers  Data centers support local economies by creating jobs, providing reliable internet services Educating the community about the benefits of data centers is crucial to ensure the successful integration of data centers into local communities. Data centers support local economies by creating jobs, providing reliable internet services, and enabling technological advancements that improve quality of life.  By highlighting these benefits, data centers can build stronger community support and enhance their social license to operate. The effort should combine outreach with online educational initiatives, collaborations with industry, academia, NGOs and multiple sources of in-the-field insight. Conclusion The data center market is poised for continued growth, driven by advancements in technology and increasing demand for digital services. By focusing on sustainability, heat reuse, and energy-efficient cooling technologies, the industry can meet this demand while minimizing its environmental impact. Engaging with communities and educating them about the benefits of data centers will further support the sustainable growth of this vital industry.

Meeting a project’s overarching design goals is vital in the building and construction sector. Creating a sustainable building could be one of these goals — driven by company commitments, federal policies, and state-based initiatives. However, the priorities of minimizing capital and long-term operating costs and maintaining project timelines often prevail.  Frequently, the perception in the industry is that these priorities — especially cost — are incompatible with designs and technologies that help decarbonize buildings. Cutting emissions and optimizing costs Organizations can take an incremental approach without compromising on cost However, our experience with heating, ventilation and air-conditioning (HVAC) systems has shown that cutting emissions and optimizing costs are not mutually exclusive when we leverage the right technologies and design strategies. Decarbonization isn't a one-time event. Reducing emissions is a continuous process with many paths. Organizations can take an incremental approach without compromising on cost. Finding the right balance requires weighing project priorities, the building’s environment, short- and long-range facility plans and available technology solutions. To achieve this balance, energy modeling is an essential tool. Weighing up design goals When it comes to sustainability and decarbonization in HVAC systems, there are three primary levers: electrification of heating using heat pumps, improving energy efficiency and using lower global warming potential (GWP) refrigerants. Cost priorities can often be aligned more easily with sustainability goals than expected Each project's physical environment and framework conditions will influence the mix of these three levers. Cost priorities can often be aligned more easily with sustainability goals than expected. For example, the local climate substantially impacts electrification.  In hotter climates, electrification is far easier than in cold ones, where heat pumps require much more electricity when heating. In extreme cold temperatures, heat pumps will eventually require a back-up like natural gas (NG) to provide supplemental heat. A hybrid system using NG as a back-up to the heat pump also avoids oversizing the heat pump to cope with the most extreme conditions – which only occur infrequently. Hybrid heating systems come into their own Hybrid systems can significantly reduce emissions compared to traditional fossil-fuel-only heating systems and save costs, especially in areas with access to cheap renewable electricity from solar PV plants, wind farms and hydro or geothermal sources. By switching over to NG when temperatures get too low or when insufficient renewable electricity is available, building owners can not only save costs but also hedge against grid outages in the coldest months of the year. It’s critical to pick the right point for your hybrid system to switch from one fuel source to another. By changing to the lowest rate — electricity or gas prices — at any particular time, you can save money while making significant CO2 savings. Alternatively, the time to switch could be based not only on energy costs but also on emissions reductions, allowing the designer to optimize around different design goals. Sustainability doesn’t necessarily command a premium A study from the National Renewable Energy Laboratory demonstrates that decarbonization and broader sustainability goals can be achieved alongside other design goals. When comparing conventional school buildings with zero-energy schools — buildings that produce as much renewable energy as they need to operate — the NREL found that the latter offers several benefits. Zero-energy schools require less energy and offset demand using on-site renewable energy. Zero-energy schools require less energy and offset demand using on-site renewable energy The study indicates that zero-energy school buildings can be designed and built within conventional budgets — and they can cost less. By applying an integrated approach to design and construction, the extra cost of the zero-energy systems can be offset by the greater efficiencies they facilitate. The study lists downsizing heating, ventilation and air conditioning among the benefits that help reduce capital and operational expenditures. However, as we have seen, balancing each building's inherent complexities is the key to achieving these benefits. This is where energy modeling comes into play. Balancing sustainability and design goals Energy models tie together all factors affecting HVAC design and installation. They are a tool for comparing many design alternatives quickly and cost-effectively to find the most appropriate solution to the project’s design goals.  Energy modeling can simulate various system configurations to show the effect of using different types of equipment, such as an electric heat pump compared to a conventional HVAC system. Modeling can also factor in decarbonization policy incentives that may affect the economics and viability of a proposed system. Various system-design options In addition, life-cycle analyses of different keys can provide a clearer long-term financial picture In addition, life-cycle analyses of different solutions can provide a clearer long-term financial picture. Models can forecast long-term costs, performance and return on investment of various system-design options, which can make it easier to get sign-off projects from investors. With its data-driven approach, energy modeling can also prevent overengineering that could lead to unnecessary expenses. A US Department of Energy study has shown that projects using energy modeling perform better and can have shorter returns on investment than those that don’t. The future of HVAC: A harmonized approach As sustainability codes, standards and regulations evolve throughout the US, energy modeling becomes increasingly vital for harmonizing environmental priorities with core design objectives — enabling balanced, effective solutions that drive greener, more resilient outcomes for buildings, businesses and the planet. By integrated advanced modeling practices into the design process, the HVAC industry can support the transition to a low-carbon future without sacrificing economic feasibility or operational efficiency. HVAC industry can support the transition to a low-carbon future without sacrificing economic feasibility. Example analysis A 54,000 ft² office building prototype, compliant with ASHRAE 90.1 standards, was modeled in Denver, Colorado, using Daikin Applied EA Pro software, powered by the US DOE’s EnergyPlus simulation engine. Rebel® heat pump rooftop units were assigned to serve the building. Two HVAC alternatives were analyzed for the heat pumps: (1) electric back-up and (2) gas back-up. The Environmental Protection Agency’s eGRID emission factors, representing the greater Denver regional grid, were used to calculate emissions, along with average electricity and gas utility rates for the region. Electric back-up scenario The results indicate that while total energy usage is lower with the electric back-up scenario—due to the higher efficiency of electric resistance heating compared to gas combustion—the annual utility costs and equivalent carbon emissions are lower with the gas back-up scenario. This is primarily because of higher electric utility rates and the electric emissions profile of the regional electric grid. The annual utility costs and equivalent carbon emissions. This example represents a specific scenario for demonstration purposes but highlights the importance of holistic, project-specific considerations when evaluating design alternatives to meet customer goals.

As the skilled workforce retires, college costs rise, and demand grows for hands-on careers, there has never been a better time for apprenticeships in industries like HVAC. As more people seek alternatives to traditional four-year degrees, vocational training offers a faster, more affordable path to meaningful work, and apprenticeships can play an important role. Apprenticeships come in many different forms, but all programs strive to build knowledge and skillsets for employees. Apprenticeships provide a long-term solution to labor shortages by developing a workforce that is trained, engaged, and aligned with industry needs. Ziehl-Abegg apprenticeship program The success of the Ziehl-Abegg training program suggests options to embrace a similar approach In the HVAC market, fan manufacturer Ziehl-Abegg offers an apprenticeship program that is a structured, rotational experience designed to prepare individuals for long-term careers in ventilation and advanced manufacturing. The success of the Ziehl-Abegg apprenticeship program suggests opportunities to embrace a similar approach throughout the HVAC industry. At Ziehl-Abegg, apprentices receive hands-on training across core business functions, including engineering, operations, sales, logistics, and assembly. The immersive approach ensures they not only develop technical skills but also understand how departments work together. Benefit from apprenticeships “The program strengthens retention, builds internal expertise, and aligns with our long-term growth goals,” says Layel Burton, Ziehl-Abegg’s Apprenticeship Coordinator. “By training apprentices in-house, we cultivate a workforce deeply familiar with our products, systems, and culture — creating highly capable employees who can grow with us as we expand our North American operations.” Businesses benefit from apprenticeships by gaining talent trained to meet specific needs, while communities gain a more resilient workforce. At Ziehl-Abegg, apprenticeships have helped to bridge labor gaps and to scale with confidence. With proper investment, apprenticeships can reduce unemployment, drive innovation, and help rebalance the economy by elevating careers that are essential but often underrecognized. Front lines of HVAC performance Contractors should understand how a fan or system was designed and tested at the manufacturing level Installers and contractors are on the front lines of HVAC performance, and well-structured apprenticeships can give them the technical depth and context needed to excel. When contractors understand how a fan or system was designed and tested at the manufacturing level, they are better equipped to install and troubleshoot it correctly, Burton contends.  “Our apprenticeship program teaches the ‘why’ behind the ‘how,’ which is something the entire HVAC chain can benefit from,” says Burton. “Manufacturers, service companies, and distributors alike should invest in mentoring programs to create field professionals who are not only capable but confident and connected to the bigger picture.” Skilled roles in ventilation and advanced manufacturing The Ziehl-Abegg program exposes apprentices to every major department — from engineering and logistics to quality and production. This cross-functional experience prepares them to step into skilled roles in both ventilation and advanced manufacturing. “Apprentices graduate not only with technical skills but also a deep understanding of our business, making them agile, dependable team members who are ready to support growth in the HVAC sector,” says Burton. Apprentice programs offer a range of benefits at any level of the HVAC supply chain. Structured partnerships Structured alliances among schools, firms, and rules ensure even training and smooth workforce entry Ziehl-Abegg is a German company, and in Europe, apprenticeships are deeply embedded in the education system and viewed as a respected career path—not an alternative to college, but a parallel track. Structured partnerships among schools, businesses, and government ensure consistent training and smooth workforce entry. In the U.S., apprenticeships are gaining momentum, but still lack the widespread infrastructure and cultural normalization seen in Europe. “At Ziehl-Abegg, with roots in Germany, we have adapted that model to our North American operations,” says Burton. “The U.S. can learn from Europe’s commitment to workforce alignment by promoting apprenticeships early, building stronger industry-education pipelines, and removing the stigma from vocational training.” Proficiency, thinking, and collaboration skills How can a company find great apprentice candidates? “A good apprentice brings curiosity, reliability, and a willingness to learn,” says Burton. “At Ziehl-Abegg, we look for individuals who show interest in hands-on work, ask questions, communicate well, and have a strong work ethic.” While technical knowledge is helpful, attitude and drive matter more, he notes. “Our program helps build confidence and competence by exposing apprentices to real responsibilities and rotating them through engineering, production, and logistics.” This experience develops technical proficiency, critical thinking, and collaboration skills. Apprentices leave the program not only prepared to take on a skilled role—but also with the mindset to grow into future pioneers. Aptitude and ambition to learn Baxley was a good match for the program because he had the aptitude and ambition to learn and work Joshua Baxley, Ziehl-Abegg Technical Sales Rep, Global Key Accounts, was an apprentice before joining the team full time. “I was drawn to apprenticeships because I was uncertain of what I wanted to do with my career,” says Baxley. “The apprenticeship program with Ziehl-Abegg provided an excellent opportunity to discover what type of career and profession I wanted to pursue by providing me the opportunity to work in all the departments at the company while paying for my education.” Baxley was a good match for the program because he had the aptitude and ambition to learn and work hard each day. These attributes helped him become knowledgeable of the company and the products as well as building strong relationships with colleagues. Four years of on-the-job experience The program allowed Baxley to get his foot in the door and gave him the opportunity to gain four years of on-the-job experience by the time he graduated. “All of this gave me the confidence each day to interact with customers and become well-versed in the world of engineering and sales,” he says. “The unexpected benefit I received from the program are the relationships and connections I was able to build throughout the company and the industry.”  “The apprenticeship at Ziehl-Abegg provided me with like-minded people my age that I created close friendships with while also building relationships with the people in each department I worked in,” says Baxley. “I highly suggest anyone to join apprenticeships if they have any uncertainty on their career path or if they can find an apprenticeship that matches their career choice and interest.”

Viessmann Climate Solutions (VCS) has combined with Carrier to become the core of Carrier’s newly formed business unit Residential and Light Commercial for European, Middle East and Africa. This business unit is now able to offer brands like Carrier, Toshiba, and Beretta next to the premium brand Viessmann, thus covering additional user segments with differentiated products at various price points. Climate system technology “The climate system technology of Viessmann Climate Solutions and the cooling-focused systems of Carrier combine two core competencies that will be crucial in responding to individual customer needs worldwide,” says Thomas Heim, President, Residential & Light Commercial HVAC for Europe, Middle East, and Africa. “Carrier expands the Viessmann portfolio in the area of air conditioning and enables seamless integration of heating and cooling.” Carrier’s acquisition of Viessmann Climate Solutions There was huge media interest in Carrier’s buy of Viessmann Climate Solutions when it was revealed There was huge media interest in Carrier’s acquisition of Viessmann Climate Solutions when it was announced more than a year ago. In media interviews, Carrier Chairman & CEO David Gitlin; Max Viessmann, CEO and Member of the Executive Board of the Viessmann Group, which owned Viessmann Climate Solutions prior to Carrier’s acquisition; and Heim presented the many advantages the combination would bring. Advantages apply both to the product portfolios, which perfectly complement each other, and to the optimized development of global markets. A year later, the feedback is extremely positive, says Heim. Latest developments in the Viessmann system The sentiment was confirmed by numerous conversations with installers at the ISH 2025 trade fair in March in Frankfurt. “The advantages of this combination between Viessmann Climate Solutions and Carrier are clearly noticeable for everyone involved,” says Heim.   The latest developments were well received by the 100,000 visitors to the booth at ISH, with particular interest in the Viessmann system connecting several products into a solution based on full stack controls platform Viessmann One. Residential and commercial sector customers The alliance meets the needs of residential and commercial sector clients with a multi-brand portfolio Also at ISH, Viessman highlighted the newly created alliance of Viessmann, Carrier, Riello, and Beretta around the theme “Power Play as One Team.” The alliance meets the needs of both residential and commercial sector customers with a multi-brand portfolio of heating, ventilation and cooling solutions for all output ranges and price levels. “Together with Carrier, we are in an even better position to provide solutions that address climate challenges by reducing CO₂ emissions and increasing energy efficiency,” says Heim. Digital tools and ecosystems The expanded product line builds on the strong longstanding collaboration of Viessmann Climate solutions with installation partners. For example, the addition of (light) commercial Carrier heat pumps to the portfolio enables leveraging together existing digital tools and ecosystems with this expanded offering. “This increases the relevance of our ecosystems for both our installers and users,” says Heim. Culture of collaboration The focus from the start has been on creating a culture of collaboration among both teams When integrating companies, it is always about bringing people together and providing a framework that allows them to unlock their full potential, says Heim. Thus, the focus from the beginning has been on creating a culture of collaboration that allows the teams from both companies to contribute their unique talents and strengths. “We are convinced that we have found the right formula and that combining Carrier and Viessmann Climate Solutions will lead to 1 + 1 > 4,” he says. “To get there, our shared purpose and values play an important role in this successful integration.” Carrier product portfolios “Companies can only be successful if they think and act globally and operate in a spirit of co-creation,” says Heim. Combining the Viessmann Climate Solutions and Carrier product portfolios creates added value for all installation partners and users. The increasing complexity of the HVAC industry is contributing to a trend toward company consolidation. “Let's be honest: in the past, you simply installed a gas boiler,” says Heim. PV installation They also offer a design tool on the Internet and even financing with the help of a partner bank Heim added: “Today, it's often about heat pumps, battery storage, photovoltaics, wall boxes and an energy management system that links everything together. It's all extremely complex. That's why we are constantly training our installers and at the same time reducing their workload." "Many of our installers don't want to climb on a roof, which is fine. We then look for facilitating a service provider that adds the PV installation to the holistic offering of our partner company.” They also offer a configuration tool on the Internet and even financing with the help of a partner bank. Climate-neutral by 2050 Data centers will also play a bigger role in the future. For example, a typical office building in Manhattan requires only three cooling units, while a data center they are currently working on requires 140. An AI chip generates seven times more heat than a conventional chip. “This market is huge, and we are determined to play an important role,” says Heim. The building sector produces 40 percent of CO2 emissions in Europe. Therefore, a transformation to renewable energies is necessary to become climate-neutral by 2050. Viessmann products and systems “For us, as a manufacturer, this means that we continue to encourage the building electrification system strongly,” says Heim. Viessmann products and systems offer installers the basis for a sustainable climate solution offering for their users. Almost all areas, from single- and multi-family houses to commercial and industrial buildings and municipal facilities, can be covered by the system portfolio. New hydraulic interface Regardless of the outdoor unit (ODU), the new components always match the indoor unit (IDU) Heim highlights three notable products as part of the Viessmann System Solution. Users can now choose between the high-efficiency, high-comfort Vitocal 250-A and the more economical Vitocal 150-A domestic air source heat pumps. Regardless of the outdoor unit (ODU), the new components always match the indoor unit (IDU). This high level of flexibility pays off for the installers in significantly shorter installation times, and users only pay for what they actually need for their heating system. The new hydraulic interface also saves time during installation. Vitocharge VX3 storage unit The Vitocharge VX3 storage unit is one of the most proven battery storage units in its class. Its maximum storage capacity of 75 kWh (5 modules of 15 kWh each) is particularly suitable for large, detached houses and apartment blocks, as well as for smaller commercial applications such as supermarkets or craft businesses. Following on from the large power classes, the smaller modules can now also be cascaded at 4.6 kVA. Flexible installation options are now available, including corner or horizontal mounting, which allow for optimal adaptation to on-site conditions.

Does anyone still think that heat pump technologies for residential applications are ineffective in cold climates? If so, they are missing opportunities available through advancements in heat pump technology. New developments in heat pumps are significantly transforming the residential HVAC market. These advanced heat pumps can maintain 100% heating capacity at 0 degrees F and operate efficiently at low temperatures. Secondary heat sources These capabilities reduce the need for secondary heat sources, leading to lower energy consumption and a reduced carbon footprint. By leveraging variable-speed technology and intelligent controls, newer systems optimize energy use, providing homeowners with both comfort and sustainability. Modern heat pumps, such as Carrier's Infinity® Variable-Speed Ultimate Cold Climate Heat Pump with Greenspeed® Intelligence, are designed to operate efficiently at temperatures as low as minus 23 degrees F, according to Carrier. Energy savings and total comfort  Additionally, for those homeowners who are hesitant to make a full swap, dual fuel technology “These systems provide reliable heating even in the harshest conditions, often eliminating the need for secondary heat sources,” says Nick Arch, Carrier’s Vice President and General Manager, Residential Solutions. Additionally, for those homeowners who are hesitant to make a full swap, dual fuel technology, in which a heat pump is paired with a gas furnace, offers an optimal solution. “The system defaults to the gas furnace depending on the outside temperatures, allowing homeowners to experience energy savings and total comfort in harsh climates,” says Arch. “By leveraging advanced technologies, heat pumps now offer a sustainable and efficient solution for year-round comfort in any climate.” Cold Climate Heat Pump Challenge Driving innovation in heat pump technology has been the participation by Carrier and other manufacturers in the U.S. Department of Energy’s (DOE) Cold Climate Heat Pump Challenge. The challenge required heat pumps to operate efficiently at temperatures as low as minus 15 degrees F, pushing manufacturers to innovate in areas such as variable-speed compressors and advanced controls. Carrier's Infinity® Variable-Speed Ultimate Cold Climate Heat Pump with Greenspeed® Intelligence was developed as part of this initiative and has demonstrated exceptional performance in harsh climates. Benefits of newer technologies  Carrier has established state-of-the-art training centers, such as one in Indianapolis “Carrier's successful completion of the challenge underscores our commitment to delivering high-efficiency, reliable heating solutions for cold climates,” says Arch. Carrier is also committed to educating both the dealer/installer community and consumers on the benefits of newer technologies through various initiatives. Carrier has established state-of-the-art training centers, such as one in Indianapolis, to provide hands-on training and certification programs. operation of new heat pump systems Additionally, Carrier offers online courses and resources through its My Learning Center, covering topics such as new refrigerants, system installation, and maintenance. For consumers, Carrier provides detailed information on its website and through marketing campaigns, highlighting the energy efficiency, environmental benefits, and advanced features of its latest heat pump technologies. Intelligence plays a crucial role in the operation of new heat pump systems. For example, Carrier's Greenspeed Intelligence integrates advanced sensors and controls to optimize the performance of heat pumps. It allows the system to adjust its output based on real-time conditions, ensuring maximum efficiency and comfort. Cold Climate Heat Pump with Greenspeed® Intelligence Carrier is expanding the capabilities of dealer/installers via its Connected Portal For instance, the Infinity® Variable-Speed Ultimate Cold Climate Heat Pump with Greenspeed® Intelligence can modulate its capacity between 30% and 100%, providing precise temperature control and reducing energy consumption. This intelligent operation enhances the overall reliability and efficiency of the system. When it comes to heat pump technology, Carrier is expanding the capabilities of dealer/installers through its Connected Portal, advanced diagnostic tools, and the integration of InteliSense Technology. Remote monitoring capability The Connected Portal allows dealers to monitor HVAC systems remotely, providing real-time data on system performance and health. This remote monitoring capability enables dealers to detect issues early, schedule maintenance proactively, and ensure optimal operation. “InteliSense Technology uses cutting-edge sensors to communicate with the system via the thermostat, storing data in the privacy-protected Carrier cloud, and delivering it remotely to Carrier experts,” says Arch. “This allows for accurate troubleshooting and maintenance, reducing downtime and improving service efficiency.” These advancements help improve customer satisfaction and reduce downtime, he says. Advanced defrost technology The precise control provided by this technology enhances the reliability and efficiency of the heat pump Carrier heat pump systems also feature advanced defrost technology that monitors the outdoor coil for the presence of frost. The system uses sensors to detect frost buildup and adjusts the compressor speed to initiate defrosting. Once the frost is melted and drained, the defrost mode concludes automatically. This functionality ensures timely and efficient defrosting, thus minimizing energy waste and maintaining optimal system performance. The precise control provided by this technology enhances the reliability and efficiency of the heat pump. Step in reducing the GWP of heat pumps The transition to R-454B refrigerant, known commercially as Puron Advance™, has been a significant step in reducing the global warming potential (GWP) of heat pumps. Carrier has worked diligently to ease the transition for the dealer/installer community by providing comprehensive training and resources since 2023, says Arch. “The new refrigerant is a near drop-in replacement for R-410A, with similar operating pressures and temperatures, making the transition smoother for technicians,” he adds. Carrier has also conducted extensive field trials and developed detailed guidelines to ensure that dealers and installers are well-prepared for the changeover, minimizing disruption and ensuring a seamless transition.

When COVID-19 disrupted international shipping, it revealed just how fragile global supply chains could be, especially for essential medical equipment. Across the U.S., hospitals and healthcare providers found themselves unable to procure basic items like masks, gloves, gowns, and even hairnets. The result was more than inconvenience; it was a systemic vulnerability that demanded urgent domestic solutions. U.S.-based PPE business Large hospital systems and national healthcare providers quickly realized that without access to basic items like masks, gowns, gloves, and even hairnets, their operations could grind to a halt.  In response, a group of investors and manufacturing pioneers launched a new U.S.-based PPE business in partnership with a hospital system and government support. Production of this type of hairnet Unlike pleated hairnets, which are dispensed from a ribbon and notoriously difficult to separate Among the products they set out to make was the sewn-style hairnet, which had emerged as the clear preference among doctors and nurses due to its secure fit, durability, and ease of use. Unlike pleated hairnets, dispensed from a ribbon and notoriously difficult to separate, the sewn version came stacked neatly in boxes and could be donned quickly in clinical settings.  But while pleated hairnets were already mass-produced on mature, readily available machinery, sewn hairnets remained a labor-intensive product, still assembled by hand in factories overseas. This posed a serious challenge, replicating the form and function of a stitched product without relying on stitching or manual labor. Automating the production of this type of hairnet would require more than off-the-shelf equipment. It would require inventing a brand new process. Building the Impossible: Process Innovation from the Ground Up Rather than recreating the manual sewing process with robotics, Wauseon Machine, a pioneering provider of integrated automation solutions, pursued a different strategy: thermoplastic welding. By heating and fusing the spunbond fibers that make up the hairnet, they could form a hem without any thread or stitching. Elastic was then inserted into the hem to complete the circular design, achieving the familiar fit and function of a sewn hairnet without a single seam. This innovation opened the door to full automation, but it also introduced new engineering hurdles. Spunbond is a thin, plastic-based material that behaves unpredictably under heat and humidity. Regulation of temperature and humidity The customer needed to produce various diameters of hairnets, rather than committing to a single standard size Static buildup became a major problem during early testing, interfering with material handling and weld consistency. To address this, Wauseon designed and constructed an environmentally controlled cleanroom inside the customer’s facility. The room provided tight regulation of temperature and humidity, including a curing area, allowing raw materials to acclimate before entering the production cell. Additionally, the design had to accommodate multiple hairnet sizes, a detail that introduced significant complexity. Because different users require different fits, the customer needed to produce various diameters of hairnets, rather than committing to a single standard size. This variability meant the equipment could not be hard-tooled or permanently configured for just one SKU. Weld alignment and product quality Instead, Wauseon engineered the system for quick and precise changeovers, allowing operators to switch between sizes with minimal downtime. These adjustments had to be fast enough to preserve production throughput and accurate enough to maintain weld alignment and product quality, ensuring that the machine could keep pace with demand without sacrificing performance across product variations. Co-Development Under Force: Managing Complexity with Setup In traditional manufacturing, the product comes first. A finalized design is validated through testing, and only then does equipment development begin. But Wauseon’s client didn’t have that luxury.  To manage that risk, Wauseon relied on its Automation Project Process (APP) They were inventing the product — defining what a thermoplastically welded hairnet even was — while Wauseon simultaneously designed the equipment to make it. This presented enormous risk. Any change to the product midstream could render the machine obsolete. To manage that risk, Wauseon relied on its Automation Project Process (APP) — a structured engineering and project management framework built for complex automation scenarios. Wauseon’s requirements APP helped both teams define safe zones, areas of the machine where inputs were fixed and development could proceed without delay. For example, packaging specifications were already determined, allowing downstream systems to be built early. Similarly, the customer had full control over the spunbond material’s width and feed format, which meant the infeed section could be locked down based on Wauseon’s requirements. By strategically decoupling stable zones from areas still under development, Wauseon avoided unnecessary rework and kept the overall project moving forward. This structure enabled the team to iterate quickly on the most volatile parts of the process without compromising the project’s needs. Engineering for Precision: Adapting to Material Variability The welds that once worked perfectly now melted straight through the material Even with early successes, Wauseon encountered a significant complication late in the project: the production samples used to design the weld process were no longer representative. The customer’s in-house spunbond machine, which came online toward the end of development, produced a much thinner material than the original samples. The welds that once worked perfectly now melted straight through the material. Rather than go back to the drawing board, Wauseon adapted. Engineers upgraded the heating elements and installed more sensitive RTD feedback sensors, enabling tighter control of weld temperatures. Pressure calibration and control algorithms  The control algorithms were rewritten to achieve ±2°F temperature stability, a significant improvement over the ±10°F tolerance used for thicker material. Pressure calibration was also fine-tuned to ensure weld integrity without deformation. These changes allowed the system to accommodate material inconsistencies, while maintaining throughput, proving that Wauseon’s process was not just functional, but robust. Speed Meets Scale: Delivering at One Hairnet Per Second Wauseon’s final solution involved two identical machines, each operating at a rate of one hairnet With market demand high and supply chain urgency driving the project, speed was just as important as precision. Wauseon’s final solution involved two identical machines, each operating at a rate of one hairnet every two seconds. Together, they achieved a sustained system throughput of one hairnet per second, a remarkable feat for a brand-new process built from scratch. Other potential technologies, such as ultrasonic welding, were considered early in the design phase but ultimately ruled out. While ultrasonic welding is common in products like N95 masks, it’s significantly slower and much harder to scale for circular weld paths. Client’s budget and volume targets In this case, ultrasonic guns were only used to create a small tack point where the elastic band joins the thermoplastic hem, just 2% of the total weld area. The other 98% was handled thermoplastically, allowing for faster cycle times, lower costs, and simplified machine design. Thanks to this hybrid approach, the system met both the client’s budget and volume targets without compromising on product quality. Since installation, the system has run daily, producing millions of hairnets that doctors and nurses across the country now rely on. This project has served as a proof of concept for what is possible, when processes and equipment are co-developed with rigor and transparency. A Model for Manufacturing Resilience For Wauseon, this project underscores their ability to partner with clients during periods of high uncertainty. Their structured APP methodology gave their partner confidence to pursue an aggressive timeline and helped navigate the technical unknowns of both product and process development. In an era where speed to market, supply chain resilience, and manufacturing sovereignty are national priorities, Wauseon Machine has proven that agile engineering can deliver. As sectors like defense, aerospace, and healthcare increasingly look to reshore production of their critical components, the hairnet project may well serve as a blueprint for how to move fast without breaking things.

Is it possible to engineer a sense of peace? That’s the challenge the development team behind Velvære has set for themselves. Velvære is a Park City, UT luxury development, which debuted its first residence in 2024. It’s named for the Norwegian concept of well-being, a way of life the entire community is built to promote and embody. Velvære “Velvære” includes not just personal satisfaction, but a sense of connection to nature; the practice of giving back to the community; an embrace of outdoor recreation; and prioritizing coziness or “koselig.” Cultivating “velvære” means bringing your physical, social, emotional, and spiritual life into balance. This holistic sense of peace and fulfillment is the new luxury. With Velvære in Park City, Bonfire Collective set out to create an intentional community where the built environment exists in harmony with both the natural world and residents’ needs, promoting this balance in every respect. The Velvære Vision Velvære is a 60-acre development adjacent to Park City’s Deer Valley Resort® Velvære is a 60-acre development adjacent to Park City’s Deer Valley Resort®. Upon completion, it will include 115 private residences, including paired homes, cabins, and sites for private estates. Velvære is designed to offer residents an elevated experience that is nonetheless completely connected to the natural world. The 2300-2400 sq. ft. cabins and 3000-5500 sq. ft. paired homes embody the concept of wellness as luxury.  With warm, natural finishes bathed in sunlight from panoramic windows, the homes will feature ski-in/ ski-out access. Homes with customizable Synergistic Sanctuary Spaces In an effort to prioritize intentional wellbeing, each residence will feature customizable Synergistic Sanctuary Spaces that transform the concept of a “healthy home.” These in-home sanctuary spaces feature environmentally forward design and amenities, a treatment room (with storage to hold equipment), steam shower, cold/hot plunge, and a HaloIR Sauna. Bonfire Collective has a discerning eye for detail born from the company’s shared roots with storied luxury home builder - Magleby Construction. They are committed to ensuring that everything from the construction materials to the mechanical systems align with their mission of creating communities for intentional living. Minimized carbon footprint As part of the commitment to “velvære,’ each residence is designed to minimize its carbon footprint and use shared energy resources responsibly. Homes are built with pathways to solar, so that residents may choose to add renewable energy collection and storage with no infrastructure retrofit required. Residents can also opt-in to a “time of use” demand response program that will automate certain activities Each home also comes equipped with an energy management system that allows residents to set their priorities and goals for energy usage – part of a ‘single pane of glass’ Crestron home automation system that manages everything from lights and AV to security and safety sensors. Residents can also opt-in to a “time of use” demand response program that will automate certain activities – e.g. running the dishwasher – to occur during times of lowest grid demand.  Making HVAC Part of the Mission HVAC system efficiency was naturally crucial to the Velvære’s sustainability goals – but the HVAC system designs for these luxury homes need to achieve more than just efficiency. They need to support the crucial ‘coziness’ element, welcoming residents in from a ski run or a summer hike to an ideal environment. That might mean toasty floors in the winter, a cool living room in the summer, or even different temperatures for different rooms and activities year-round. It is also critical the HVAC systems avoid adding complexity to overall home management. Bonfire Collective prioritized bringing HVAC control into the Crestron home automation system, unifying home management and preserving a simple, elegant end-user experience. “Sustainability is only one aspect of our goals for Velvære,” said Chad Magleby, Partner at Bonfire Collective, adding “It’s part of wellness, which is in turn part of ‘velvære.’ We believe that a specific desire for personal wellness will drive more change than a broad preference for sustainability.” Engineered for Coziness Bonfire Collective contracted Gunthers Heating, Cooling, and Plumbing to engineer Velvære’s HVAC systems Bonfire Collective contracted Gunthers Heating, Cooling, and Plumbing to engineer Velvære’s HVAC systems. This family-owned business has served American Fork, UT continuously for over a century; they brought both advanced expertise and a deep connection to the community, central to the project’s mission. Gunther’s Heating, Cooling and Plumbing designed a system that delivers on the concept of koselig year-round. A natural gas radiant floor system warms the homes in the winter, melting snow from parkas and mittens and warming residents’ toes as they step out of their boots after a black diamond run. Zoned heat pumps Zoned heat pumps control the upper-end of the set point range, allowing residents to maintain a cozy kitchen without allowing home office and master suite spaces on the upper floors to get stuffy. In the summer, the same heat pumps deliver zoned air conditioning throughout the home. The specifying engineer selected Mitsubishi SMART MULTI Hyper-heating heat pumps for this project. These highly versatile Inverter units offer superior efficiency, and their multi-position design allows Gunther to spec them for any Velvære floorplan. A typical Velvære paired home includes three SMART MULTI units, as well as an AprilAire Humidifier to keep these homes comfortable in the dry Mountain West climate. Sophistication Meets Simplicity Indeed, ideally, they should not have to manage the HVAC system at all The engineering team recognized that residents would not want to separately manage radiant and electric heating systems. Indeed, ideally, they should not have to manage the HVAC system at all: temperature and humidity should be orchestrated by the Crestron home automation system without a second thought. To unify operation of the two-stage heating system, manage zoning control, and enable two-way communication between the Crestron home automation system and Mitsubishi Inverter units, the specifying engineer turned to Airzone. Airzone VAF solution Airzone is a major provider of intelligent HVAC control solutions, with an exclusive library of HVAC manufacturer protocols. For the homes of Velvære, Gunthers Heating, Cooling and Plumbing used the Airzone VAF solution. This flexible zoned HVAC system controller supports control of ducted and ductless systems from major manufacturers. Airzone VAF can control heating, cooling and schedules for multiple zones, allowing the engineers to optimize the comfort of each Velvære home. Uniquely, Airzone allows simultaneous control of a two-stage heating system with both radiant and air from a single thermostat. Airzone VAF connects to Crestron home automation system Airzone VAF connects directly to the “single pane of glass” Crestron home automation system. Airzone offers a dedicated RESTful API driver for the Crestron Home® OS that allows HVAC controllers to be integrated without custom programming, additional wiring, or WAN connection. Via the Airzone controller, the HVAC system becomes part of the holistic home management system Via the Airzone controller, the HVAC system becomes part of the holistic home management system. The user only needs to interact with one interface. When the user changes a set point, or the home enters automation, such as “eco mode,” or “vacation mode,” the Crestron system communicates to the Airzone controller, which then translates the commands into the requisite manufacturers’ protocols for the radiant heat system, heat pumps, fans, temperature sensors, etc. The home is managed as a unified whole, in alignment with the spirit of Velvære. The Velvære Journey Begins As Velvære welcomes its first residents, Bonfire Collective is offering luxury homeowners a new kind of mindful living. The community is designed to support connection to the natural world as a top priority. Homeowners who wish to carefully manage their carbon footprint can monitor and optimize their energy sources and consumption through the Crestron home automation system. They can also monitor their natural gas consumption specifically via an exclusive pulse device on home meters. Elegant HVAC and home automation system design The community’s elegant HVAC and home automation system design is integral to achieving that balance The community’s elegant HVAC and home automation system design is integral to achieving that balance. “Our laboratory testing indicates that properly controlled Inverter HVAC systems offer energy savings of 45% on average compared to traditional units,” said Victoria Garcia Massimo, North America Operations Manager for Airzone. She adds, “Zoned systems can achieve energy savings of 60% or more. When an HVAC system is part of a holistic building and energy management system, as in Velvære, these effects are amplified. The more deeply we integrate these systems, the more good we can achieve.” Tracking the community’s performance Bonfire Collective and their partners plan to track the community’s performance. “Our intent on a community scale is to exist in balance with nature,” says Magleby, adding “As Velvære grows, we plan to monitor aggregate energy consumption and eventually seek ways to offset our fossil fuel usage through the HOA.” Integration with IoT systems The concept of ‘velvære’ recognizes that well-being requires connection. Integration with IoT systems, such as home and building automation is essential to participating in this vision. By designing homes and a community that promotes enjoying and taking care of the natural world, Velvære represents an ambitious path forward for the industry, where HVAC systems are a key element of a better, more connected life.

Tourism has long been a key economic driver for Philadelphia—which is the 6th largest city in the U.S. and designated as a UNESCO World Heritage City. The Pennsylvania Convention Center (hereinafter Center), located in the heart of Center City, Philadelphia, serves as one of the City’s pillars in supporting the conventions and meetings industry. With typical visitor traffic welcoming over 1 million guests a year, the 2 million square foot Center helps drive $600 million worth of meeting and convention activity in Philadelphia. CO2 emissions reductions Supported by a collaborative quasi-government structure that represents city, county, and state stakeholders The positive economic ripple effect buoys business to the region’s hotel industry, dining and entertainment venues, retail stores, transportation commerce, and historical and cultural attractions. Supported by a collaborative quasi-government structure that represents city, county, and state stakeholders, the Center—a $1.3 billion investment—serves as a critical regional economic engine, as well as a source of civic pride.  The 2020 pandemic, and the associated downturn in convention and meeting business, served as an opportunity for the Center to upgrade and modernize the facility, enhance health and safety infrastructure, and redouble its commitment to sustainability and related CO2 emissions reductions. Strategic upgrade plan With a goal to modernize the facility and reduce operational environmental impact, plus offer visitors a safe, comfortable, and positive customer experience, the Center’s stakeholders wisely invested $15 million in infrastructure upgrades. The strategic upgrade plan included deploying state-of-the-art air purification and ventilation, technologies that lower water use, energy-efficient LED lighting, new reflective roofing, expanded recycling, and streamlined management of HVAC, lighting, and power. Siemens alliance provides expertise needed for digital change Siemens has supported numerous multiphase, infrastructure improvement and upgrade projects To help convert this vision into reality, the Center decided to turn to its long-term technology partner—Siemens. Since the Pennsylvania Convention Center’s inception in 1993, Siemens has supported numerous multiphase, infrastructure improvement and upgrade projects. To help the Center implement its latest modernization and decarbonization initiatives, Siemens contributed technology and expertise in the following ways: Energy efficiency Through a Siemens Energy Services Conservation (ESCO) partnership, the Center was able to fund and finance energy-efficient products and services. For example, the Siemens Financial Services (SFS) organization was able to assist in the funding of new needlepoint bipolar ionization technology for air purification. SFS provided $15 million through a lease solution, which included (The Center is always tax-exempt; they are a state-affiliated facility run by an Authority) non-appropriation provisions to meet the Center’s needs. A guaranteed savings model was used across two phases of the project to fund $24 million in smart infrastructure investments (payments for the technology and services were funded through the resulting energy savings over time, so no large upfront payments were required). Sustainability Siemens grant to these efforts consisted of multiple digital keys that enabled more sustainable day-to-day operations The Center’s sustainability efforts involved multiple dimensions of their operation. Initiatives included water conservation, recycling within the food and beverage service areas, active energy management (more efficient light and temperature controls, insulation, weatherproofing), green procurement practices (prioritizing purchases from vendors who are committed to delivering high sustainability goods and offerings), a marshaling yard for convention related tractor trailers traffic (which results in significant CO2 emissions reductions through the avoidance of excessive back-and-forth site equipment delivery and removal), and efforts to migrate to clean energy sources (50% of the Center’s power supply is now derived from wind energy). The Siemens contribution to these efforts consisted of multiple digital solutions that enabled more sustainable day-to-day operations. For example, cross-facility smart building technology such as meters and sensors (for gathering electricity, gas, and water consumption data) and analysis software (for centralizing and interpreting that data and optimizing environmental controls to limit waste and maximize operational efficiencies) helped to build a solid foundation for energy savings and resource conservation. Process improvements implemented during Phase I of the modernization project resulted in $686,000 in operational cost savings through 2021. In addition, installing LED lighting throughout the Convention Center helped save 4.5 million kWh in annual power consumption. In addition, Siemens provided demand response and building control software to help cut energy costs and CO2 emissions. On the automated demand response side, the Center can now interact directly with the local electrical utility company to better manage energy costs. Suppose the utility company needs to address greater power demand across its grid. In that case, the Center can contribute by curtailing its energy use over specific periods in exchange for discounted energy prices. In this way, it helps to temporarily bring stability to the local grid when demand is high, such as on a very cold or scorching hot day, and pay much lower electricity rates in return. On the building controls side, a Siemens software front end (Desigo CC) enables an integrated building automation system fault detection using advanced algorithms and machine learning to predict failures before they happen. This continuous automated commissioning capability improves equipment uptime, promotes timely preventative maintenance, and enhances occupant comfort. Resilience The team developed a custom-engineered solution to control the integrated functioning of the two plants Siemens also worked with the Center’s control and mechanical engineers and programmers to create a proprietary plant control solution that would enhance facility resilience through redundancy and reduce energy consumption. Although the facility hosts heating and cooling plants at both the East and West ends of their complex, those facilities had never been connected. The team developed a custom-engineered solution to control the integrated functioning of the two plants. Now the engineering team can run only one of the central plants to heat and cool the entire building when it is not fully occupied. Engineers can also choose which equipment is best suited to run based on the building’s requirements for that particular day. Integration of the two central mechanical heating and cooling plants enhances plant redundancy and reduces CO2 emissions. Now, 1.3 million kilowatt hours (kWh) of power is saved each year through interconnection and optimal use of one plant at a time, with a second plant already in place as a backup in case of unanticipated downtime. Environmental controls To ensure the highest possible indoor air quality and ventilation, the Siemens and Center teams engaged in a series of Variable air Volume (VaV) HVAC systems upgrades and performed the cleaning and sealing of HVAC ductwork and coils. These two initiatives have saved 200,000 kWh of energy and 1,900 thermal units of natural gas per year. In addition, the attachment of multiple Variable Frequency Drives (VFDs) to motors helped to save 530,000 kWh of power and 2,300 thermal units of natural gas. The combined energy efficiency, sustainability, resilience, and ventilation solutions reduced PCC baseline energy consumption by more than 18 percent. High precision control drives visitor comfort and convenience Siemens team also periodically issues energy audit reports to ensure that all systems are optimized Besides these significant gains in energy efficiency and CO2 emissions reductions, the new digital solutions have also enhanced the flexibility of overall facility operations. Now, every meeting room, concourse, ballroom, and exhibit hall, can be individually monitored for air quality and temperature in real time. Sensors connected to the air handling units feed data into the control system, giving building managers real-time access to system performance data. The result is a total focus on air quality that emphasizes the health and well-being of visitors and of staff who work and do business in the Pennsylvania Convention Center. Digitalization of operations has also enabled visitors to view real-time building energy efficiency and air quality dashboards through large “green screens” that can be accessed from multiple locations within the facility. From a facilities data gathering and analysis perspective, the Siemens monitoring and control solutions help to support the Center’s facilities staff by tracking and modeling energy use and generating sustainability report metrics. Siemens artificial intelligence software also monitors chilled water, making necessary adjustments to conserve additional energy, and enables predictive maintenance by detecting potential issues before they result in unanticipated downtime. The Siemens team also periodically issues energy audit reports to ensure that all systems are optimized to achieve the highest performance levels. Decarbonization efforts spur global recognition and accreditation LEED is an internationally recognized green building certification system developed by the USGBC Thanks to these long-term collaborative efforts, the Pennsylvania Convention Center has attained both a LEED Gold certification and a Global Biorisk Advisory Council (GBAC) STAR™ certification. LEED is an internationally recognized green building certification system developed by the U. S. Green Building Council (USGBC). It provides building owners and operators with guidelines for implementing practical and measurable green building design, construction, operations, and maintenance solutions. The LEED rating system recognizes projects that develop and implement sustainable design strategies for better environmental performance. The Center began the Global Biorisk Advisory Council (GBAC) STAR certification process in 2020 and received the accreditation on outbreak prevention, response, and recovery in 2021. Recognized as the gold standard for safe venues, the Pennsylvania Convention Center is now one of the largest venues in the Northeastern U.S. to receive GBAC STAR™ accreditation. GBAC STAR™ Facility Accreditation identified the Center as a showcase example of commitment to ensuring a clean, safe, and healthy environment for its employees, customers, and stakeholders. Conclusion Future vision includes ongoing sustainability improvements. The Pennsylvania Convention Center’s modernization project has reduced baseline energy consumption by more than 18 percent and has helped to establish high-level partnerships focused on sustainable operations. The ability to ensure visitor safety and comfort while maintaining high sustainability has been transformed from a vision to a reality. Ongoing sustainability investments will play an essential role in PCC’s future growth and development. With such smart building technologies in place, the Center can now serve as a blueprint for how other large buildings—arenas, performing-arts venues, museums, and more—can create action plans for infrastructure improvement upgrades that exceed industry standards for sustainability best practices. 

Healthcare facilities require a substantial amount of energy to operate. In fact, the average hospital consumes approximately 250% more energy than a comparably sized commercial building, according to the U.S. Department of Energy. As hospitals face increasing financial pressure to boost revenue while cutting costs, many are turning to energy-reduction initiatives as a strategic remedy. At the heart of those efforts is often the HVAC system, which accounts for roughly one-sixth of a hospital’s total energy consumption. Broader energy initiative The broader energy initiative successfully delivered both energy savings and operational improvements That was the case at Baptist Health Medical Center – Little Rock, Arkansas's largest private, not-for-profit hospital. The century-old facility initially sought to replace its aging wooden cooling tower, which supported the hospital’s HVAC system. However, the project soon evolved into something much more ambitious: a comprehensive mechanical system overhaul designed to significantly reduce energy consumption. While the broader energy initiative successfully delivered both energy savings and operational improvements, it was the new cooling towers — ironically, the original catalyst for the project — that emerged as a surprisingly large contributor to the hospital’s ongoing power savings. Operating with efficiency  “Originally, the owners wanted to go with an engineered plastic cooling tower because they liked the fact that it was corrosion-proof, required far less upkeep, and came with a 20-year warranty,” says David Buie, an Account Manager in Controls Sales at Powers, who helped kick off the project. Based in North Little Rock, Arkansas, Powers is an HVAC, controls, and service company that partnered with the hospital to upgrade its cooling towers. However, as the project progressed, hospital leadership decided to broaden its scope to include a comprehensive review and optimization of the entire mechanical system. Bidding for the new cooling towers The final decision came down to two material options: HDPE engineered plastic and stainless steel To guide the expanded initiative, the hospital brought in an independent energy-efficiency engineering firm, which required competitive bidding for the new cooling towers. The final decision came down to two material options: high-density polyethylene (HDPE) engineered plastic and stainless steel. “Once the engineering company saw the energy that could be saved by utilizing the HDPE towers, there was really no looking back,” adds David Buie. A healthier bottom line Engineered plastic cooling towers were first pioneered by Delta Cooling Towers in the 1970s, and many of those original units remain in operation now. The energy savings delivered by these towers can be attributed to three key features: a modular design, multiple highly efficient motors and fans, and the use of variable-frequency drives (VFDs). “Because of the way Delta’s towers are essentially separate cells that work together, the hospital can stage them down when they’re not all needed,” explains Jared Hendrickson, Controls & Equipment Lead at Powers, adding “This can amount to huge savings on energy.” Precise load management Each cell contains two fans, all powered by VFDs that automatically reduce motor output Baptist Health Medical Center selected Delta’s TM Series, which consisted of 20 individual cells providing a total cooling capacity of 7,000 tons.  The modular design allows for precise load management, and each unit is equipped with smaller 60-inch fans, which significantly reduce energy consumption. Each cell contains two fans, all powered by VFDs that automatically reduce motor output when full fan speed isn’t required. Capabilities of the HDPE cooling towers “When you operate the fan motors at 80% speed or less, you're saving about 50% on power,” said Jared Hendrickson, adding “So, when you're talking about that much savings spread across 40 motors, the energy reduction is extensive.” In addition to the superior turndown capabilities of the HDPE cooling towers, these units also feature much smaller motors – 15 horsepower (hp) compared to 150 hp in the stainless-steel alternative – further contributing to long-term savings. Saving energy and improving operations  In addition to reducing energy consumption, Baptist Health Medical Center has also significantly lowered maintenance costs. One key reason is the construction of the HDPE cooling towers, which feature a one-piece molded casing. The design eliminates joints and seams — common failure points in traditional towers that often lead to leaks The design eliminates joints and seams — common failure points in traditional towers that often lead to leaks and ongoing repair needs. The towers are also equipped with direct-drive fans, eliminating the need for gearboxes that require frequent maintenance and routine oil checks. Additionally, while all cooling tower systems require chemical treatments to control algae, pathogens, and sediment buildup – all of which can hinder performance – the HDPE towers are immune to the corrosive effects of these chemicals. Another advantage for contractors “The chemical treatment is going to eat away at a metal tower, even a stainless tower, over time,” notes Jared Hendrickson. Installation time offers another advantage for contractors. HDPE systems can often be installed in just a day or two, compared to the multiple days, or even weeks, required for towers made from other materials. “There are only two pieces held together by eight bolts,” explains Jared Hendrickson, adding “Compare that to a thousand bolts and a thousand metal components on other towers. There's also no gasketing and caulking of panels before assembly. It’s a very simple installation process.” A clean bill of (energy) health  Energy-efficiency measures don’t just reduce consumption, they can improve overall operations through optimized HVAC performance and smarter energy management. At Baptist Health Medical Center, the new cooling towers, installed at ground level, have also contributed to a quieter, more controlled medical environment. Hospitals face unique challenges when it comes to energy use. Compliance with regulations like ASHRAE Standard 170 – which governs temperature, humidity, and air exchange rates – places constant pressure on facility executives, energy managers, and engineers to find sustainable, high-performance solutions.  Through careful selection of its cooling tower system and strategic mechanical upgrades, Baptist Health’s flagship facility achieved measurable, long-term power savings without compromising compliance or patient care.
