International standards

Pfannenberg, Inc., a pioneering manufacturer of thermal management and signaling technologies, highlights its thermostat products, including the tried and true FLZ 510-530 Series and FLZ 541-543 Series, now featuring universal temperature control dials with both Fahrenheit and Celsius ranges. Pfannenberg thermostats provide an essential temperature control solution to maintain optimal conditions for control cabinets, reducing maintenance, saving time, and cutting costs.  Pfannenberg thermostats “Pfannenberg’s thermostats play a vital role in controlling temperature with electrical enclosures, whether by managing heaters or regulating the operation of our trademarked FilterfanⓇ cooling solution,” said Dan Langendorfer, Associate Product Manager. In outdoor applications, Pfannenberg thermostats can ensure that a control cabinet remains ‘artificially’ dehumidified by tightly controlling the temperature inside an electrical enclosure so that it stays above ‘dew point’. Keeping the temperature above dew point keeps water from condensing out of the air, and thus keeps electrical enclosures from short-circuiting from the formation of condensation. Integration with UL 508A panels The thermostats’ universal temperature control dial, displaying temperature in Fahrenheit and Celsius simultaneously, eliminates the need for constant conversions and calculations, reducing the chance of error and saving time for professionals dealing with diverse global standards or meeting the unique preferences of their industry.   The FLZ 510-530 Series is a single thermostat option from Pfannenberg and the FLZ 541-543 Series is their twin thermostat option. Single thermostats feature changeover contacts, while twin thermostats provide the flexibility to switch at different temperature ranges. Not only do twin thermostats save space, but they also contribute to energy efficiency. All Pfannenberg thermostats feature ultra-compact designs, easy mounting options, independent controls, and provide durable, long-lasting, and energy-saving solutions. Pfannenberg thermostats are also UL certified, ensuring seamless integration with UL 508A panels. 

Following discussions alerting the industry about potential supply shortages of HFC-based refrigerants during its HVACR Next Generation Congress in Riyadh on 28 October 2025, Eurovent Middle East has published its first industry guidance on the impending refrigerant transition in the region. With the ratification of the Kigali Amendment by the Kingdom of Saudi Arabia in September, the GCC countries are set to phase down hydrofluorocarbon-based refrigerants (HFCs) starting with a baseline freeze in 2028, followed by phase-down from 2032. Shortages of HFC refrigerants While the phase down begins only gradually with reductions of HFCs consumed or produced in steps of 10% every 5 years initially, the industry will be faced with potential supply shortages of HFC refrigerants due to the economic growth and thus rising demand for cooling in the region. During the HVACR Next Generation Congress in Riyadh, Markus Lattner, Managing Director of Eurovent Middle East, warned: “The phase down will start from a baseline of HFCs produced or consumed over the period from 2024 to 2026." "This means that if we add the accumulated growth in the building sector in the next years to the 10% reduction in the first step, we can very likely look at a sudden shortage of HFC-based refrigerants in excess of 30%, when the first reduction happens in 2032. To prevent wider shortfalls and bottlenecks, it is imperative that industry and governments act now!" Implementation and harmonization of safety standards The Position Paper by Eurovent Middle East addresses alternatives and outlines recommendations to industry and governments on how to avoid bottlenecks in the future. It recommends the use of alternatives to HFCs immediately, wherever possible to be done safely, encourages upskilling initiatives to ensure that the workforce is prepared to handle alternative refrigerants, and calls for implementation and harmonization of safety standards and regulatory frameworks across the region to facilitate the switch towards cooling and refrigeration systems, which work with low global warming potential refrigerants. The association’s position paper can be downloaded free-of-charge on the Eurovent Middle East website.

Heating, ventilation, and air conditioning (HVAC) systems aren’t just essential to controlling temperatures and air quality inside buildings — they could contribute towards massive global savings. An ‘Efficient cooling scenario’ proposed by the International Energy Agency (IEA) suggests that doubling the energy efficiency of air conditioning could reduce investment and running costs in these systems by nearly $3 trillion by 2050. Here, Chris Johnson, Managing Director of bearing specialist SMB Bearings, explains how one way to make HVAC systems more efficient is through the better use of advanced sealed bearings. Integrity of components HVAC systems operate in harsh environments where dust, moisture, and contamination threaten the integrity of components.  Those components include bearings, which are essential in the fans, motors, and compressors used in commercial air handling units, industrial refrigeration systems, and large-scale ventilation systems. These systems are commonly found in factories, hospitals, and office buildings. Safety risks as overheating components Eventually, the motor will struggle and consume more energy to maintain its performance Take an HVAC system in a large commercial building, for example. If bearings begin to fail, then friction increases, which causes components to overheat. Over time, the excessive heat can lead to the misalignment of shafts and fans. As this misalignment worsens, vibrations can increase and place further stress on the system. Eventually, the motor will struggle and consume more energy to maintain its performance. If left unchecked, the motor can seize entirely, halting airflow and disrupting climate control. These issues not only result in higher energy costs, but can present safety risks as overheating components can lead to fire hazards or breakdowns. Reliability of HVAC systems For example, during heat waves in Ghaziabad, India, extreme temperatures have caused HVAC systems to overheat and ignite, leading to a rise in air conditioner fires. According to The Times of India, many of these fires are due to poor maintenance, overloaded circuits, and aging components. Fortunately, sealed bearings — bearings enclosed with seals or shields to prevent contamination and retain lubrication — can address some of these challenges. They not only enhance the reliability of HVAC systems, but can also reduce the frequency of maintenance interventions. This leads to an overall lower total cost of ownership (TCO). Optimising bearing procurement using TCO A common mistake when procuring bearings for HVAC systems is to focus solely on the initial cost A common mistake when procuring bearings for HVAC systems is to focus solely on the initial cost. This can be misleading, as bearings with a lower upfront price could result in higher maintenance requirements and replacement costs over time. Instead, buyers should adopt a TCO approach that considers the entire lifecycle costs of the bearing, including purchase price, installation, maintenance, and potential downtime. Let’s use the example of gearboxes and geared motors, which are integral to many HVAC systems and provide the necessary torque and speed control for various components. Bearings within these systems ensure smooth operation, reduce frictional losses, and increase the HVAC system’s overall efficiency. integrity of lubricants and protecting internal components Sealed bearings are especially suited to gearboxes, because they prevent the ingress of lubricants and contaminants that would otherwise compromise the gearbox’s performance. Sealed bearings contribute to the longevity and reliability of gearboxes and geared motors By maintaining the integrity of lubricants and protecting internal components, sealed bearings contribute to the longevity and reliability of gearboxes and geared motors, and ultimately improve the performance of the overall system. Sealed bearings also offer significant cost savings over time. Their ability to resist contamination reduces the need for frequent lubrication and maintenance, thereby extending service life and enhancing system reliability. Sealed bearings in HVAC systems Lubrication is critical for sealed bearings in HVAC systems as it minimizes friction, dissipates heat, and prevents wear. Sealed bearings can come pre-lubricated, in order to require minimal maintenance. However, in demanding environments or high-load applications, periodic relubrication may be necessary to maintain the bearing’s performance and extend its service life. Ensuring safety and compliance in explosive environments Certain HVAC applications operate in environments where explosive gases or dust are present Certain HVAC applications operate in environments where explosive gases or dust are present. In such settings, it is paramount to ensure that all components meet safety and compliance standards. Bearings used in these environments must meet stringent standards, like ATEX 2014/34/EU, a European Union regulation for the use of equipment and protective systems in potentially explosive atmospheres (ATEX) where a mixture of air, gases, vapors, mists, or dusts can ignite under certain operating conditions. There is also the international IEC System for Certification to Standards Relating to Equipment for Use in Explosive Atmospheres (IECEx). Choosing the right bearings Selecting the appropriate bearings for HVAC systems involves considering factors such as load capacity, speed, operating environment, and maintenance requirements. Sealed bearings for HVAC systems come in three main types: contact seals, non-contact seals, and metal shields. Selecting the appropriate seal type ensures HVAC system efficiency, longevity, and reliability Contact seals provide superior protection against dust, moisture, and contaminants; but they can also increase friction and reduce speed. Non-contact seals offer a balance with good contamination protection and minimal impact on speed, which makes them ideal for high-speed HVAC components. Meanwhile, metal shields prevent larger particles from entering, and are suitable for applications where speed and temperature resistance are critical. Selecting the appropriate seal type ensures HVAC system efficiency, longevity, and reliability. IEA’s Efficient cooling scenario The IEA’s ‘Efficient cooling scenario’ highlights the need for more efficient air conditioning solutions to prevent excessive electricity demand growth. It projects that doubling the energy efficiency of air conditioning by 2050 would prevent global electricity demand from growing by 1,300 gigawatts and save up to 2.9 trillion USD. High-performance components, like sealed bearings, already play a vital role in achieving these efficiency gains. By preventing contamination, minimizing maintenance and improving reliability, bearings can support the global drive for energy savings.

This year’s Clean Air Day falls on Friday the 19th June.  In its eighth year, Clean Air Day has become the UK’s largest campaign dedicated to raising awareness of air pollution and its impacts on health and the environment. It also encourages individuals and organizations to take practical steps to reduce pollution and protect public health, both inside and outside buildings. Air quality should be a concern for everyone, but certain sections of society are disproportionally impacted than others, children in particular, which is why this year on Clean Air Day we are urging policymakers, educators, and building professionals to prioritize clean air in and around our schools and homes. Children Face a Greater Risk Children are particularly susceptible to the harmful effects of air pollution Children are particularly susceptible to the harmful effects of air pollution. Unlike adults, their lungs and immune systems are still developing, and their smaller body size means they breathe in more air relative to their body weight. This increased inhalation rate, coupled with greater time spent outdoors—especially during commutes to and from school—results in elevated exposure to pollutants like nitrogen dioxide (NO₂) and particulate matter (PM). Serious health consequences for children 15,000 children under the age of five were admitted to London hospitals with breathing difficulties in 2023 The effects of breathing in polluted air can have serious consequences for children.  Clean air campaign group Mums for Lungs revealed that 15,000 children under the age of five were admitted to London hospitals with breathing difficulties in 2023. Although it’s not possible to determine how many of the admissions are directly linked to air pollution, a study by the University of Dundee found that children are significantly more likely than adults to be hospitalized due to respiratory issues caused by air pollution. Mental effects of air pollution Air pollution is not only linked to physical ailments such as asthma and bronchitis but also to decreased attentiveness and slower cognitive response times in classrooms. What's also very concerning is that the damage to children’s lungs is often irreversible. The Royal College of Paediatrics and Child Health has called for "bold but necessary policies" to protect young people and improve air quality, particularly around schools and hospitals. Unfortunately, many new schools are being built in areas that exceed World Health Organization air pollution limits. Between 2017 and 2025, 147 new schools in England—86% of all planned or constructed—will be in such zones. Surprisingly, there is no legal obligation to consider air quality in school planning, despite children spending up to 35 hours a week in these environments. Identifying the Invisible Threat Indoors However, indoor air pollution is an equally serious, yet often overlooked, issue When we talk about air pollution, the conversation often focuses on outdoor sources like vehicle emissions. However, indoor air pollution is an equally serious, yet often overlooked, issue—especially in schools and homes. Recent research from Birmingham University at a Cardiff high school found that particulate matter concentrations inside classrooms were influenced not just by outdoor pollution, but also by indoor activities, classroom location, and even flooring materials. In homes, sources of indoor pollution include cleaning chemicals, cooking emissions, and even everyday items like candles or air fresheners that release volatile organic compounds (VOCs). Without adequate ventilation, these pollutants accumulate, leading to poor indoor air quality (IAQ) that can affect children's health and ability to learn or sleep well. Schools, which typically include a variety of spaces such as classrooms, kitchens, sports halls, and even swimming pools, present their own set of ventilation challenges. Each of these environments requires specific ventilation solutions to ensure a safe and healthy atmosphere. The Role of Ventilation in Healthier Environments Effective ventilation is one of the most important tools we have in the fight against indoor air pollution. Properly specified and maintained ventilation systems can significantly improve IAQ by removing pollutants and regulating CO₂ levels. In classrooms, balanced mechanical ventilation with heat recovery—such as the Nuaire XBOXER XBC range—is ideal. These systems are capable of ventilating multiple rooms and come equipped with filters to remove incoming pollutants, offering both health and energy efficiency benefits. School ventilation challenges challenges Sports halls present different challenges, particularly with high CO₂ levels and odours Sports halls present different challenges, particularly with high CO₂ levels and odours. Packaged Air Handling Units are well-suited to these environments, offering high-volume air movement and the option of occupancy or CO₂ sensors to control the system efficiently based on use. For indoor swimming pools, where humidity and chlorine levels are high, Air Handling Units are also ideal, although will need to be corrosion-resistant. Meanwhile, in school toilets—frequent sources of unpleasant odours and bacteria—twin fan technology ensures continuous extraction, even if one fan fails. Kitchens benefit from bifurcated fans, which position the motor outside the airstream to prevent grease build-up and reduce maintenance needs. These tailored solutions demonstrate how smart ventilation can enhance IAQ across varied school settings. A Call to Action This Clean Air Day Clean Air Day is more than a date on the calendar—it’s a call to action. Road transport is a key contributor to NO₂ emissions, and efforts to promote walking, cycling, and public transport are important. However, tackling indoor air pollution is equally critical. We must recognize that protecting children from air pollution is not optional; it is a moral and public health imperative. No child should have to breathe polluted air simply to learn, play, or sleep. By investing in targeted ventilation strategies and supporting evidence-based policy, we can give every child the clean air they deserve—and build a healthier future for all.

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.”

Johnson Controls’ Advanced Development Engineering Center (JADEC) in New Freedom, PA., about 25 miles from Philadelphia, highlights and demonstrates the company’s capabilities related to development, testing and manufacturing.  The 357,000-square-foot facility is an advanced engineering and testing facility for water-cooled chillers, air-cooled chillers, air handlers, compressors, and heat pumps. Much of the development in the facility centers on advancements in a critical vertical market for the HVAC industry – data centers. Big challenge  Data centers are a big challenge – and a huge opportunity – for the HVAC industry. “You cannot ignore the tremendous growth opportunity in this vertical,” says Todd Grabowski, president, Global Data Center Solutions for Johnson Controls. Unlike other verticals that are more dominant in certain geographic regions, data centers are growing everywhere globally – and at a breathtaking pace. “As a growth company, it is critical that we have solutions to handle the growth and serve the customers in the data center market,” says Grabowski. Performance of various components Testing options at JADEC include testing the performance of various components Testing options at JADEC include the ability to test the performance of various components in a controlled environment that approximates how they will operate in the customer’s real-world setting. There are more than 20 testing labs available at the JADEC campus, covering some 250,000 square feet.  “We want everyone to understand the unique position Johnson Controls is in to use our technology and our manufacturing scale to accomplish desired outcomes,” said Grabowski. Non-compressor solution  JADEC displays the full breadth of what they offer, including a non-compressor solution using direct evaporative cooling and an air-cooled unit that uses a screw compressor or a magnetic-bearing centrifugal compressor. Also included are various water-cooled chillers.   Johnson Controls owns, develops, tests, and manufactures all the compressors on display. Customers are assured of getting a fully engineered and supported solution from Johnson Controls (e.g., no third-party compressors). Johnson Controls owns, develops, tests, and manufactures all the compressors on display. Colocated data centers  Grabowski emphasizes that each customer installation has site-specific needs that require unique solutions that Johnson Controls seeks to fulfill. The company works closely with data centers, including those operated by “hyperscalers” such as Amazon, Microsoft, Apple, and Meta, and colocated data centers that rent space and capacity to customers based on their growth and needs. Colocated data centers come in a variety of sizes and types; some of them are operated by companies such as Equinix and NTT. Data center solutions Sustainable methods include the use of refrigerants with ultra-low GWP The sustainability of data center solutions is a bigger issue than ever, given the sheer volume of data centers being built to handle the world’s growing computational needs. Sustainable approaches include the use of refrigerants with ultra-low GWP, and water-free systems that do not require higher costs or create higher demands on a locality’s water infrastructure. Magnetic bearing centrifugal compressors are more energy-efficient because no friction is lost in the compression; also, the equipment is quieter. Impact on global electricity demand “Sustainability has always been an important aspect, and now it is critical in 2024 and beyond,” says Grabowski. Because data centers are huge consumers of energy, they can put more strain on the electricity grid and have a big impact on global electricity demand. Lowering energy usage helps to address the challenge.  “We want to contribute to energy efficiency, be good stewards of water, and reduce noise,” says Grabowski. Increasing the challenges are the proliferation of new artificial intelligence (AI) chips, more common in newer data centers, which need more power and create more heat than older chips.   Advantages of water cooling  The liquid contained in a cold plate on top of the chip is denser than air and accept more transferred heat Closed-loop liquid systems are used to cool individual chips, an application that does not cause a strain on local water supplies. The liquid contained in a cold plate on top of the chip is denser than air and can accept more transferred heat.  However, chillers and cooling towers lose water through evaporation and can strain local water supplies. Johnson Controls is researching and testing systems that provide the advantage of water cooling without losing excess water to evaporation. Air-cooled systems  In contrast, air-cooled systems can cool chips to a point, but may not provide enough cooling for high-density chips. Johnson Controls provides air-cooled machines up to 600 tons and water-cooled systems up to 4,000-plus tons.  “As chip technology evolves, the way you cool, secure and automate the entire data center changes as well,” says Grabowski. “Companies such as Johnson Controls must keep up with evolving trends and provide unique solutions.” As chips become denser from a heat-generation perspective, systems must be optimized from a footprint and energy standpoint.  JCI provides air-cooled machines up to 600 tons and water-cooled systems up to 4,000-plus tons. Technological solutions “As chip density increases, we will have technological solutions ready for the next generation of chips when they come out,” adds Grabowski.  Johnson Controls is also involved in developing new approaches to managing the heat from data centers, such as the possibility of recapturing the heat and circulating it into a district-heating system for a nearby community, university, or hospital. A more widely deployed approach in Europe, the concept of district heating is gaining acceptance in the U.S. market. {##Poll1725623180 - What is the biggest challenge the data center market presents to the HVAC community?##}

Mitsubishi Electric Trane HVAC US LLC (METUS), a pioneering supplier of all-electric, all-climate Ductless and Ducted Mini-split and Variable Refrigerant Flow (VRF) heat-pump and air-conditioning systems, shared a customer success story on Weber State University, an energy-conscious school that uses all-climate heat pumps throughout its campus buildings. VRF solution from Mitsubishi Electric Weber is also using a ductless, water-source VRF solution from Mitsubishi Electric The Ogden, Utah-based university has installed a ductless, water-source Mitsubishi Electric Hybrid VRF™ heat pump system in the SkySuites, a building that houses the Weber State Athletics Department, coaching staff offices, press box, 26 suites, 150 club seats, and a study area for student-athletes. Weber is also using a ductless, water-source VRF solution from Mitsubishi Electric in the Noorda Engineering building. These solutions allow Weber State University to further its goal of reaching carbon neutrality by 2040. Conventional HVAC systems “Replacing our conventional HVAC systems has improved the comfort of students, faculty, and other staff, and it has significantly reduced our energy costs,” said Justin Owen, Interim Director of Operations for Weber State University. “We’re now exclusively installing Mitsubishi Electric all-climate heat pump solutions across campus because of their performance, functionality, easy-to-use thermostats, and warranties.” Key advantage of VRF and Hybrid VRF technology Weber State also cites zoning as a key advantage of VRF and Hybrid VRF technology Weber State also cites zoning as a key advantage of VRF and Hybrid VRF technology. Zoning provides more personalized comfort and improves efficiency. Each space has its own thermostat, allowing occupants to heat or cool their space to their comfort level. The Hybrid VRF system also pairs well with a variety of indoor unit options, including ceiling cassettes and wall-mounted units, to match the school’s different needs. Key technology in modernizing buildings Weber State University’s buildings have historically been cooled with chilled water from a central water plant and heated with steam from a central steam plant, both of which are energy-inefficient compared to modern systems. Plans are underway to convert the entire campus to Mitsubishi Electric Hybrid VRF solutions, which use water instead of refrigerant indoors and are a key technology in modernizing buildings. Approximately half of the HVAC systems on campus are fully electric now. Climate heat pump technology Approximately half of the HVAC systems on campus are fully electric now “Weber State University’s use of next-generation, all-climate heat pump technology make it a prime example for other universities looking to take steps toward future-proofing their buildings,” said David Archer, Vice President of Commercial Business at Mitsubishi Electric Trane HVAC US LLC. “Not only are Mitsubishi Electric VRF and Hybrid VRF systems energy-efficient, but they also allow university facility operators to customize and enhance comfort for faculty, staff, students, and visitors campuswide.” Water-source VRF solutions In addition to using all-climate heat pump technology to heat and cool its buildings, Weber State is also educating younger generations about these HVAC systems. Most parts of the Noorda Engineering building’s ductless, water-source VRF solutions are on display to students, with parts labeled and exposed. This setup empowers faculty to use the HVAC system as a teaching tool for students in its electrical engineering, mechanical engineering, and energy engineering programs.

The Olsen Group, based in Boca Raton, Florida, is a national pioneer in HVAC energy optimization. Donald Olsen and his seasoned team of HVAC control specialists have been in business for two decades, integrating energy-saving solutions into over a thousand commercial and large-scale residential projects. In the process, the Olsen Group has become one of North America’s top suppliers of Verdant thermostats. Verdant devices leverage intelligent occupancy sensors and proprietary software to reduce HVAC runtimes by 45 percent on average. HVAC control integration Verdant’s effectiveness, reliability, and broad compatibility have made Verdant the energy management solution of choice for thousands of hotels and MDUs, including multifamily buildings, senior living, and student housing.  The Olsen Group has forged a productive two-way partnership with Verdant. Donald Olsen and his team have made it a priority to share data, customer feedback, and requirements with Verdant – and Verdant, in turn, has come to rely on Olsen when they need to field test a new solution. In May of 2024, Verdant reached out to Olsen for help with a new pilot program aiming to facilitate more effective HVAC control integration, easier service, and deep energy savings for MDU projects around the globe. The Challenge Commercial VRF systems have an extremely attractive set of upsides for hotel operators Inverter (VRF) system design is becoming increasingly common in hospitality settings. Commercial VRF systems have an extremely attractive set of upsides for hotel operators. They are significantly more energy efficient and quieter than traditional VTACs or PTACs; they can provide simultaneous heating and cooling to different zones for optimal guest comfort; and they allow both individual room-level setpoint control and building-level centralized management. However, the majority of VRF units cannot connect directly to a third-party smart thermostat. Because they rely on proprietary manufacturer protocols for variable speed commands and internal diagnostics, VRF units require an external control solution to facilitate bidirectional communication with Verdant thermostats. Installation and commissioning process Every additional component in a system adds complexity and opportunity for human error. In hotels, that complexity is multiplied across hundreds of rooms. “HVAC systems are installed dark for new builds, with no power running to the site,” says Donald Olsen, President and Owner of the Olsen Group. “There’s no way to test as we go. If there are any mistakes during installation, we find out about it when the lights go on after project completion.” And mistakes are nearly inevitable. Some third-party controllers have prominent dipswitches that can be easily snagged or tripped during transportation or installation, altering their configuration and causing them to fail once the system is powered. These switches are often accidentally tripped multiple times throughout the installation and commissioning process, pioneering to a never-ending cycle of errors and service calls. VRF control solutions  Adding to the issue, not all third-party control keys have the ability to retrieve and solve system error codes “Once properly configured and installed, VRF control solutions tend to be incredibly reliable,” says Olsen. “Getting them there is a real challenge, however. Accidents, human error, and repeated recalibrations can drive serious project overruns and client dissatisfaction.” Adding to the problem, not all third-party control solutions have the capability to retrieve and translate system error codes. “If the central management system isn’t getting certified manufacturer control signals from the control device, it may no longer recognize the thermostat. The system will continue to function, but it will always show up in the central manager with an error message,” warns Olsen. Airzone Aidoo Pro control solution These false error reports degrade the overall utility of the central management system, robbing operators of the ability to detect and mitigate problems proactively and requiring onsite testing to diagnose any issues. As VRF systems become the norm for hospitality projects, Verdant needed a solution to reduce the possibility of accidental misconfiguration and improve visibility into system functionality. They called on Olsen to conduct a pilot program, retrofitting sixteen VRF units in the Jacksonville Beach, FL Springhill Suites with the Airzone Aidoo Pro control solution. The Solution For the pilot, the Olsen Group outfitted each VRV unit in the loop with an Aidoo Pro controller The Jacksonville Beach Springhill Suites is a 156-room hotel with a state-of-the-art Daikin VRV rooftop chiller system. The Airzone Aidoo Pro ships preconfigured for the specific HVAC unit model, reducing the possibility for errors during initial installation. For the pilot, the Olsen Group outfitted each VRV unit in the loop with an Aidoo Pro controller. This 1:1 system design simplifies operations and troubleshooting: Any issue can be immediately traced back to a single unit, minimizing the scope and duration or repair downtime. “The Airzone Aidoo Pro offered two key upgrades as a VRV control solution,” says Olsen. “First, the dipswitches are recessed, making them much harder to trip accidentally. Second, Aidoo makes the system much easier to service. We can read error codes, run tests, and diagnose issues remotely, without ever needing to disrupt a guest’s stay.” Airzone’s expansive library This advanced remote management is enabled by Airzone’s expansive library of manufacturer protocols. “Because of our close relationship with HVAC manufacturers, Aidoo Pro can provide the proprietary control signals the central management system is expecting to see,” says Borja Fernandez, Director of OEM Solutions, Airzone. “That preserves all the features of the HVAC unit and thermostat, while also eliminating persistent false error codes. With Aidoo Pro, the central management system can function as a single-pane-of-glass HVAC monitoring and control solution for the building, as intended.” Results and Next Steps The pilot program is expanding to new builds around the globe, including projects in the UK Olsen reports that Springhill Suites is happy with their upgraded VRV system. “They have more visibility into the system and fewer services calls,” says Olsen. “When there is an issue, we can diagnose it remotely for faster resolution and less guest room downtime. It’s a much better customer experience overall.” Verdant is encouraged as well. This pilot program is expanding to several new builds around the globe, including projects in Central America, the Caribbean, the UK, and the EU. HVAC energy savings “There is a massive untapped market for energy-efficient HVAC upgrades in the Caribbean region,” says Olsen. “Energy costs there can exceed a dollar per kilowatt hour. Cost-effective devices like Verdant thermostats and the Airzone Aidoo Pro pay for themselves very easily in that scenario.” Verdant and the Olsen Group have built global brands by helping commercial properties realize significant HVAC energy savings. Through the Airzone Aidoo Pro pilot program, they are continuing to innovate, enabling reliable integration and enterprise-grade control on highly efficient VRF units. “The demand for commercial VRF control is definitely there,” says Olsen. “With Verdant and Airzone, we can deliver it with ease.”

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, entranceways, 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, the 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 heating units Specialized heating units are designed to stop drafts in their tracks before they laid throughout a building 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 the shutdown, helping attack drafts at their source, making the best use of available heat and prolonging the life of the heater. Equipped with integrated thermostats 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 fewer 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 Fan-forced wall or ceiling heaters are built with easily accessible power on/off switches for safety Safety and style go hand-in-hand. While selecting a heater that fits a building’s esthetic 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 the 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.

To offset the cost of tenants’ monthly electric bills and provide prospective residents with high-quality HVAC upgrades that prioritize comfort and performance, Samuels Associates, owner of the Fenway Triangle luxury apartments, sought a new, building-wide heating solution that was not only cost-effective but also added a modern touch to the building’s extravagance. QMark® MUH-Pro+ and CU900 electric heaters with SmartSeries® Plus (SSP) digital BACnet thermostats from Goodyear HVAC Sales proved to be the ideal solution. Heat in a contemporary design “From their energy efficiency, quiet operation and low maintenance to the fact that they can be controlled individually for personalized comfort, electric heaters offer several benefits in apartment buildings,” explained Andrew Martin, Manager of Product Management with Marley Engineered Products® (MEP). “Delivering supplemental comfort heat in a contemporary design, these heaters are ideal for a variety of spaces including school hallways, church vestibules, transportation terminals, stairwells, entrances, lobbies, mechanical rooms and more.”  Installing Heaters while Maintaining esthetics Buildings boast modern frills and discreet and esthetically good HVAC plans that act quietly Steps away from the iconic Fenway Park, the Fenway Triangle is an 891,000-square-foot complex comprising more than 570 luxury apartment units, as well as an eclectic mix of national and local retailers, restaurants, shops and green spaces. Since opening in 2006, the building needed to address issues with its HVAC systems and controls, which were leading to high monthly electric bills. The culprit? More than 50 outdated competitor electric terminal heaters, which offered only on/off controls and needed to be operated manually. If the maintenance team forgot to shut off the heaters, "The Fenway" would incur the cost of each heater running at full capacity at a rate of about 27 cents per kilowatt-hour. Another challenge facing Fenway Triangle: The emergence of new luxury apartment complexes. These buildings boast modern amenities and discreet and esthetically pleasing HVAC systems that operate quietly. They pose significant competition for “The Fenway”, as tenants increasingly prioritize indoor air quality (IAQ) and HVAC performance when selecting their luxury residences. To remain competitive in the luxury apartment market, investing in HVAC upgrades to replace outdated equipment is imperative. QMark MUH-Pro+ and CU900 electric heaters  Heaters were installed in elevator banks, stairwells, worker lounges, hallways, and facility To combat the rising cost of heating each unit within the building, MEP’s local Sales Representative, Goodyear HVAC Sales, worked with HVAC distributor Equipment Direct Sales, Inc. (EDSI) to provide the client with energy-efficient QMark MUH-Pro+ and CU900 electric heaters from Marley Engineered Products. Designed to maintain occupant comfort and a comfortable environment, the heaters were installed in various elevator banks, stairwells, employee lounges, hallways and inside the building’s recently upgraded building management system (BMS) room.  “Equipped with SSP digital thermostats that provide connections to BACnet MS/TP BMS for easy control and monitoring, the MUH-Pro+ and CU900 units only run when directed by the internal schedule of the BMS,” said Matthew Goodrich, President of Goodyear HVAC Sales. “Use of the BMS saves time and reduces personnel costs by eliminating the need to travel to the heater site. And, if a BMS is not available, the maintenance team can simply use the built in seven-day programmable scheduling feature.”  New electric heating units Cost-Effective Heat for Unmatched Comfort and Lower Monthly Bills In tandem with EDSI, Goodrich and his team installed several brand-new electric heating units in The Fenway’s BMS room to provide cost-effective warmth without taking up floor space or creating a tripping hazard.  “Innovation and collaboration converged as we tailored a custom heating solution, seamlessly blending functionality and aesthetics,” explained Goodrich. “In fabricating this solution for the client, our dedicated team and the coordination of skilled contractors transformed this building into a space that harmonizes comfort and elegance and exemplifies the blending of form and function.”  Full control of the entire heating system The thermostats include features that allow the building’s maintenance team to monitor each heater The success of the project resulted in an extremely satisfied customer. Already, the SSP thermostats have provided cost savings by turning on the heaters only when needed, resulting in less electricity usage throughout The Fenway. Additionally, the thermostats include features that allow the building’s maintenance team to monitor each heater individually from within the BMS room, granting them full control of the entire heating system and eliminating the daily trips previously needed to turn each heater on and off.  “We’re already seeing the savings associated with the upgraded controls,” said John Belmonte, Head of Trilogy Operations for the Fenway Triangle. “Being able to control over 40 heaters locally allows our team to focus on tenant needs without being bogged down by the time it takes to touch each individual unit. We’re eager to work further with the Goodyear team on other buildings in the neighborhood.” Innovative approach and exceptional achievements To acknowledge the innovative approach and exceptional achievements demonstrated by the Goodyear team in overcoming the challenges faced during this project, Marley Engineered Products awarded Goodrich the 2024 Jim Herring Memorial Silver Fox Award at its recent national sales meeting. “This award for excellence in solution design embodies the spirit of Herring, who left a lasting legacy of designing creative solutions for specialized applications, was always up for a challenge and most happy when solving a unique heating or ventilation problem,” said Sean Pesce, Director of Sales for Marley Engineered Products. “Matthew and his team at Goodyear perfectly captured Jim’s talent for finding creative solutions to the most complex issues and left a lasting impression on the client.”

Tucked into the rolling hills of northern Kentucky just 15 miles south of bustling Cincinnati, the city of Independence offers its 28,000 residents access to urban amenities in a picturesque, rural setting. The landscape is dotted with farmhouses, but one 200-year-old home on a sprawling 150-acre property has a unique story.  Originally a log cabin in the 1700s, the house has been transformed over the centuries, with structural elements, updates, and modern comforts added along the way. The renovations, including a large expansion in the1920s and a handful of recent modernizations, have kept the home livable throughout the generations. historical integrity with comfort The current owner, Dr. C.J. “Jay” Hellmann, was 6 years old when he moved into the house. His fond memories of growing up on the farm are coupled with memories of sweating through the summer months. With its historic charm and cherished family memories from across the decades, the home means everything to him and his family, who value the farmhouse’s historical integrity but also require modern comfort. Efficient and effective cooling and heating Hellmann focused on making the house more comfortable by finding effective and efficient ways to heat and cool As Hellmann prepared the home for his daughter and son-in-law to move into, he focused on making the house more comfortable by finding effective and efficient ways to heat and cool the living areas. “The family had an oil furnace. They’re very expensive to run, not very efficient, and [produced] dirty air. The next generation moved in and wanted something a little more comfortable and cleaner,” said Josh Williams, Sales Manager, Corken Steel Products. Project highlights The farmhouse had both a rich history and antiquated infrastructure. It was steam-heated by a large, inefficient oil furnace in the basement and did not have ductwork or an air conditioner. Hellmann and his family felt the lack of air conditioning acutely during Kentucky’s humid summer months, which frequently see temperatures over 90°F. The family sought an HVAC solution that would fit their needs without compromising the farmhouse’s historic aesthetic. Inverter technology As the owner of Call Now Heating and Cooling, an Independence-based HVAC contracting business, Hellmann was familiar with LG but hadn’t considered the brand’s inverter technology until he met an LG sales representative at a local event.  The two discussed the benefits of heat pump technology and how an LG system could suit the home’s needs. Shortly after, Hellmann scheduled a walkthrough of the house, which helped determine the best comfort solution to condition the home evenly and efficiently while preserving its charm. Quality and availability Hellmann and his team collaborated with Corken Steel and LG to design an energy-efficient solution “I have an HVAC business and I can pick any equipment I want,” he said. “I picked LG for a few reasons, including the quality of the equipment that we looked at, the availability, and that it matched, it looked good in the home. The support from LG was also a key part of my decision.” Hellmann and his team at Call Now Heating and Cooling collaborated with Corken Steel, a ductwork fabricator and HVAC wholesaler, and LG to design an energy-efficient solution that tackled the challenges of bringing modern HVAC products into a coveted older home. Challenges Older homes can pose significant heating and cooling challenges due to inadequate insulation, uneven heat distribution from existing systems, and a lack of ductwork. With traditional systems, this combination of obstacles can lead to expensive and invasive installations where large units take up valuable space. Hellmann sought a solution that would avoid these disruptions and involve fewer adjustments to the home’s footprint and architecture. He found that an all-electric inverter heat pump system from LG addressed all these challenges. Solution The team decided on a whole-home solution using two Multi F Max withLGRED° units to deliver customized comfort to every part of the house. One low-static ducted unit can heat and cool the first level, and six low-wall ductless console units can condition the second floor. After selecting the system, the team began installing it in harmony with the farmhouse’s environment, which required hiding the equipment wherever possible. Together, they determined how to work around steam pipes, where to run lines and drains, the layout of units, and where to place the equipment to maximize airflow. Given the farmhouse’s historic nature, this was not a simple installation; it required the team’s ingenuity and dedication to maintaining the integrity. Refrigerant and power/communication lines The first-floor units use minimal duct runs installed through the floors and into the basement The first-floor units use minimal duct runs installed through the floors and into the basement, where the old boiler system was located. Rather than installing multiple ducted systems for heating and cooling throughout the farmhouse, the team ran refrigerant and power/communication lines discretely through the attic for the low-wall console units in the upstairs rooms and sunroom and utilized an old, unused, laundry chute to run lines into the basement and outdoor units. Comprehensive solution “Our representative from LG made it exceptional to work together. He always answered when we had a question, and if he didn’t know the answer, he told us who to call to get what we needed,” said Brad Helton, HVAC Technician, Call Now Heating and Cooling. The strong relationship between Call Now Heating and Cooling, Corken Steel, and LG made it possible for Corken and Call Now to design a comprehensive solution to fit Hellmann’s needs, streamline installation, and create benefits they hadn’t originally anticipated. Result Ultimately, the team’s main priority was met, the new HVAC system complemented the home’s aesthetic and preserved its historic charm, efficiently heating and cooling. The LG low-wall units’ appearance blended nicely with the farmhouse’s style and their flexibility and small footprints meant they could be placed with consideration for the rooms’ designs. Aesthetics aside, the Hellmann farmhouse reaps many additional benefits from the LG system. The homeowners now enjoy consistent, customized comfort along with reduced noise, improved indoor air quality, and greater energy efficiency. All-electric heating All-electric heating means Hellmann no longer pays for oil to heat the home in Kentucky’s cold winters “The system has better air quality, it’s easier to and the units put out a very hot heat and very cool air compared to a normal heat system,” said Casey Whalen, Installation Manager, Call NowHeating and Cooling. All-electric heating means Hellmann no longer pays for oil to heat the home in Kentucky’s cold winters. This is a significant contributor to energy savings. Zoned comfort control With the old furnace, he’d spent nearly $1,500 every 30-40 days for oil. Now, with the all-electric LG system, he pays about a quarter of that, even in the coldest months. Zoned comfort control offered by the LG system also contributes to energy savings. Using thermostats, remote controls, and smartphone applications, the family can set each zone in their home to a different temperature or even turn units off altogether, depending on the room’s use and occupancy. All-electric LG inverter heat pump “Having a new LG system in this home is very exciting,” shared Hellmann.“We’re able to have cool air in a house that’s 200 years old and has never had cool air before. This was the first summer that you could sit in here and be comfortable, have fresh air, and comfortably use different rooms like the porch. It has made the house more livable, much more useful, and much more comfortable.” Breathing new life into a centuries-old home is a tough task. For the family, the fix has been renovations and modernizations over the years. And Hellman says none stands to benefit the family more or give them a greater return on their investment than the all-electric LG inverter heat pump system.

Water and energy efficiency company Cenergist has been appointed by Ashford Borough Council to provide a nutrient neutrality solution for a new 1,000 home development using its patented Control Flow technologies. The site is within a nutrient-sensitive area that requires any new development to mitigate against increased localized waterway pollution.  Cenergist’s patented Control Flow products are pressure-independent flow controllers that provide long-term reductions in water wastage and nutrient emissions from homes as well as improve the performance of existing gas boilers. By eliminating the fluctuations in the water supply caused by system pressure changes, Control Flow provides a steady precise water flow to the home.  Control Flow installations By installing in existing homes in the area, Control Flow creates the headroom for new builds Performance tested in both the UK and Europe, Control Flow has been shown to reduce water and energy bills by up to £360 per annum with a 98% customer satisfaction rating. By installing in existing homes in the area, Control Flow creates the headroom for new builds.  Under the contract, Cenergist will determine the precise number of Control Flow installations required to offset all the nutrient emissions from the new development at Ashford. Working with the council, it will then contact and persuade householders of the benefits of the technology and then carry and complete the installations and provide the necessary assurance to allow Natural England to sign off on the development. The project follows on from the use of Control Flow to unlock a development in Crawley that had previously been held up due to water scarcity concerns. Nutrient neutrality strategies Paul Mckenner, head of strategic projects at Ashford Borough Council, said: “The retrofitting works is part of a series of measures to unlock approximately 1,000 new dwellings which the Council has a vested interest in.” In England, waterways including lakes, rivers and estuaries are protected under the Conservation of Habitats and Species Regulations 2017. Natural England has mandated that developments located near vulnerable watercourses require nutrient neutrality strategies to prevent negative ecological impact." Caroline Gray Mason, business development director at Cenergist commented: “Nutrient neutrality is a significant challenge facing developers as they look to deliver much-needed housing in a sustainable, responsible way. It is essential to be on the front foot with nutrient mitigation measures to minimize the environmental impact of new developments in vulnerable areas. Securing this contact with Ashford Borough Council is a testament to Control Flow’s role to mitigate nutrient pollution by reducing the level of emissions from existing homes.”
