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.

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.

Data centers play a pivotal role in supporting the flow of information across our digital economy. However, the transmission of large amounts of data also requires a lot of energy. Viewing data centers as potential heat sources offers an opportunity to use this otherwise wasted heat to warm nearby homes and businesses using technologies like heat pumps and heat networks. The approach will lower the environmental impact of these buildings filled with computer servers, and it will support the transition to renewable heating as we look toward net zero. Heat recovery systems Heat recovery systems are designed to facilitate the re-use of heat energy via technologies like heat pumps Heat recovery systems are designed to facilitate the re-use of heat energy via technologies like heat pumps and heat networks, says Simon Prichard, EMEA ITC Business Leader, Mitsubishi Electric, within the Living Environmental Systems division. The heat generated by data centers, usually around 30-35°C (85-90°F), is increased by heat pumps to 70-80°C (160-175°F), making it suitable for heating nearby buildings or supplying hot water. “However, when choosing which heat recovery approach to go for, it's important to take into account the data center’s size, location, and proximity to the desired reuse location,” says Simon Prichard, adding “These factors determine the most efficient method for heat recovery and distribution.” Reusing heat from data centers via heat pumps “Reusing heat from data centers through heat pumps and heat networks drives down costs by reducing the amount of heat going to waste and ultimately increasing energy efficiency,” continues Simon Prichard. However, Simon Prichard emphasizes these cost benefits must be communicated and outlined clearly to ensure stakeholders are aware. More awareness will, in turn, drive adoption forward. Wider awareness and adoption Wider awareness and adoption are already happening with plans for utilizing waste heat within London's district heating networks, notes Prichard. The scheme uses ejected heat from a data center to power heating demand for nearby homes A real-life example is Amazon’s Tallaght data center in Dublin, which is the country's first low carbon district heating network. The scheme uses ejected heat from a data center to power heating demand for nearby homes, and peak requests in winter are satisfied by dedicated heat pumps and a heat pump module. The network is estimated to reduce pollutant emissions in the South Dublin County region by nearly 1,500 tons per year. Mitsubishi Electric’s CPD-Certified Guide Mitsubishi Electric’s newly released CPD-Certified Guide aims to educate data center owners, managers and policymakers on the role heat reuse can play in decarbonizing these buildings. “It provides insight into how we can reduce the carbon footprint of these spaces by viewing them as a source of heat energy, as well as the solutions available and what needs to be considered before making the switch,” says Simon Prichard, adding “In doing so, it aims to support owners and managers in transitioning to heat recovery in their building and reducing the environmental impact of these spaces to support the United Kingdom’s wider journey towards net zero.” Communicating the benefits of heat reuse in data centers “Communicating the benefits of heat reuse in data centers can promote greater cooperation from stakeholders – whether that's owners and managers, governments, or manufacturers,” says Simon Prichard. Raising awareness of the environmental impact of data centers and the role heat recovery can play in reducing that impact can position data centers as part of the solution for a decarbonized future. Developing heat networks “Continuing to develop heat networks at the same scale as other European countries will also help make reusing this energy to heat surrounding buildings a reality and put what we see across other countries into practice in the UK,” states Simon Prichard.

With a reputation for uncompromising integrity, HDG Legacy is an experienced voice in the hospitality industry for those looking to build, own, and operate hotels. As both a respected developer and preferred management company, the Legacy team employs its core values of teamwork, communication, innovation, leadership and resourcefulness, and has an established reputation for positively impacting the hospitality sector. Currently, Legacy manages and maintains nine hotels that it owns, with its tenth opening July 2025. Rising energy and water costs  A commitment to improving and innovating hotels means that Legacy is alive to the economic challenges facing hoteliers, not least in operational challenges because of rising energy and water costs. With profit margins often razor-thin, even small innovations can mean the difference between profit and loss, so it was no surprise that Legacy looked to Anacove’s unique AI- and Cloud-powered Smart Thermostats, Leak Detection and Asset Management systems to help give its hotel clients the edge in their energy and water management. Anacove’s Smart Thermostats  “One of my core beliefs is that operating a business that respects the environment in terms of how resources are utilized is important just because that's the right thing to do – but there's also an economic benefit,” explained Navroz F. Saju, Founder and Principal at HDG Legacy. “We initially tested Anacove’s Smart Thermostats across our express properties, before piloting them in one of our larger hotels, and we were so impressed with the results (we actually have the data showing the savings for 2024-25 thus far – very impressive!) that we are looking to roll out the solutions across our other properties.” Electricity consumption reduced He continued, “We started using Anacove Smart Thermostats in July 2024 at the Holiday Inn Express Crystal River, and based on historical data and usage, electricity costs on our utility bills are 35.94% lower per occupied room.” “The Holiday Inn Express & Suites Silver Springs-Ocala’s electricity costs were 33% less than what we’d budgeted for per room, with the Holiday Inn Express & Suites Inverness-Lecanto coming in at 43% lower than budgeted in electricity usage.” Features of Smart Thermostats  Anacove’s Smart Thermostats are innovative IoT devices with advanced sensors Anacove’s Smart Thermostats are innovative IoT devices with advanced sensors that monitor temperature, humidity, air quality, barometric pressure, current weather conditions, daylight conditions and guest presence. They seamlessly integrate with HVAC systems through existing hotel WiFi infrastructure, allowing for centralized control throughout the hotel. This enables continuous optimization of each room, regardless of occupancy status, leading to immediate and sustained cost savings. Unlike other occupancy-sensing thermostats, Anacove Smart Thermostats remain active even when guests are asleep or have left their pet in the room. Optimizing HVAC Cycles  Learning from each room’s thermal behavior – heating and cooling coefficients – the thermostats optimize HVAC cycles, resulting in reduced peak energy consumption, and maintenance of guest comfort with less energy usage. “I have been very pleased with the transition to Anacove Smart Thermostats, and we will continue to replace older, less efficient thermostat technology with Anacove thermostats,” added Saju. “They are easier to operate – for staff and guests – and install than others on the market – irrespective of their superior energy-saving performance – and are incredibly responsive.” Anacove’s staff and support Such was their ease of use that Legacy’s skilled maintenance staff installed the Anacove Smart Thermostats themselves, but Saju is keen to point out how engaging Anacove was throughout the process. “Their support has been excellent. Even though the thermostats are easy to install and operate, if there is ever a question that needs answering the Anacove team is there to back us up very quickly and in a very expert way,” he said. “I've been very comfortable with their price point – I actually think that their thermostat pricing is the most competitive I have found – and with their after sales service and the technology’s ease of use they are very customer-centric indeed.” Anacove’s AI-enabled water management systems  In addition to rolling out Anacove’s Smart Thermostats incrementally across his hotels, Saju is also deploying the company’s AI-powered, cloud-maintained Toilet Leak Detectors and Asset Tracking Systems. The AI-enabled water management systems go beyond basic leak detection. While sensors installed in water tanks or behind walls detect even the tiniest leaks, it’s the AI that identifies anomalies, pinpoints problem areas, and alerts maintenance teams before the issue escalates – saving water, money, repair costs, and mitigating guest inconvenience. Anacove’s Asset Management System  Anacove’s Asset Management System equips hotel assets such as luggage carts, rollaway beds, cribs, housekeeping trollies and other movable items with location tags, which, thanks to the cloud-maintained AI system, helps to track down missing items, triangulating their exact positions, streamlining retrieval, reducing loss, and improving overall resource management. “We all expect a lot from our hotel’s front desk,” said Saju. “They’ve got to check people in, the phone's ringing, someone wants a bandage and then suddenly someone will check in and say, ‘where's the luggage cart?’” “The fact that they're immediately able to log in to the Anacove cloud dashboard on their phone and see exactly where the cart is – usually in a guest’s room – is an incredible time-saving benefit, enabling them to locate the cart’s exact location so that they can repurpose the cart for another guest’s use. In the past they would have to ring around guests’ rooms to find it – a waste of time and valuable resources.” Anacove AI cloud brain The performance of all four Anacove technology services (thermostats, toilet leaks, staff and asset trackers) are monitored and analyzed by the company’s AI cloud system, effectively a brain hovering over key operational areas of the hotel that make intelligent decisions. This ‘Anacove AI cloud brain’ – the only system of its kind – looks at the whole hotel as a single living entity, autogenerating reports that allow hoteliers to clearly see the return on their investment. The AI-enabled, cloud-connected energy management solution uses one inclusive dashboard, with a data-rich, monthly ‘flash report’ that provides a summary of how much energy has been saved, what's going on in terms of potential toilet leakage, etc. Easy and energy efficient  Overall, Saju is delighted with not only Anacove’s innovative, unique, AI-powered, cloud-connected devices, which are exceeding Anacove’s own expectations, but also by the company’s service and support. “They advertised a saving of about $12.00 per-room per month for the Smart Thermostats, which was pretty significant, but we're beating those numbers,” he explained. “Overall, all their technology is easy to install and use. There are huge savings, and – importantly – our general managers are very happy!” “Anacove’s after-sales service has also been second to none, and they have been incredibly receptive in helping us adapt the systems to our own requirements. I am a huge fan of Anacove and the team there; they're good people and I'm so glad that we're able to work together.”

One such initiative, a partnership with American Plant Maintenance (APM Steam), focuses on steam system maintenance, aiming to optimize efficiency and reduce energy consumption, while maintaining high-quality patient care. The Challenge Many of Northwell Health’s facilities rely on complex steam systems for heating, sterilization Many of Northwell Health’s facilities rely on complex steam systems for heating, sterilization and other critical operations. Maintaining these systems is essential to attain operational efficiency and patient safety. Yet, steam traps — essential components that remove condensate without losing steam — are prone to failure over time. A single leaking or plugged trap can cause substantial energy loss and increase carbon emissions, while driving up operational costs. With hundreds of steam traps across multiple hospitals, identifying and addressing failures required a proactive and scalable solution by the hospital team. The Solution In 2019, Northwell Health partnered with APM Steam, Woburn, Mass., to implement an annual steam system maintenance program. This program involves surveying steam traps across the hospital network, identifying issues and performing necessary repairs. APM Steam manages the utility incentive process, ensuring that Northwell receives available rebates APM Steam’s comprehensive approach includes inspecting steam traps, replacing or repairing faulty components, installing insulation to reduce heat loss, and descaling heat exchangers to attain optimal performance. Importantly, APM Steam manages the utility incentive process, ensuring that Northwell receives available rebates while providing detailed data to guide maintenance decisions and prioritize high-impact improvements. Reducing CO2 emissions Haneef Khan, a member of Northwell Health’s Energy Steering Committee, explains the value of this approach: "The energy and cost savings were staggering. Combine that with incentive funding for energy reduction by National Grid and ConEd, we can achieve payback in well under 12 months by proactively maintaining steam traps, system insulation and heat exchangers across our hospital portfolio." He adds, "We’re reducing our impact on the planet by reducing our CO2 emissions. The dollars we save in energy can be used to improve the quality of services we offer the communities we serve." Results The partnership has delivered substantial results for Northwell Health. Since January 1, 2022, APM Steam has surveyed 9,817 steam traps across the hospital network, resulting in remarkable savings: $2,403,672 in gas and electric savings 946,500 Natural Gas Therms saved $1,162,551 in utility incentives secured These efforts have yielded an overall return on investment (ROI) in just 1.4 years. The reduction in natural gas consumption not only translates to cost savings but significantly reduces Northwell Health’s carbon footprint. These results support the hospital network’s broader sustainability goals, while improving operational efficiency and freeing up budget for other critical improvements. Ongoing support from APM Steam Northwell Health has prioritized energy efficiency by participating in incentive programs Over the years, Northwell Health has prioritized energy efficiency by participating in incentive programs offered by National Grid and ConEdison.  These incentives have been instrumental in offsetting project costs and accelerating payback periods. With ongoing support from APM Steam, Northwell ensures that its steam systems operate safely and efficiently — minimizing waste, maximizing savings, and maintaining reliability across its hospitals. Conclusion The success of Northwell Health’s steam system maintenance program underscores the importance of proactive, data-driven maintenance in reducing energy consumption and operational costs. By partnering with APM Steam, the hospital network has demonstrated that regular maintenance and strategic use of utility incentives can drive significant financial and environmental benefits.

It underscores the potential for innovative partnerships that can help to further reduce emissions in the refrigerant industry through its on-site refrigerant recovery service (Rapid Recovery®), refrigerant buyback programs, and wholesale supplier reclaim program (Refri-Claim™). HCFC-22 destruction project The ACR methodology has included HCFC-22 as eligible for destruction-generated offsets since 2017 Wren and A-Gas formed a partnership to provide Wren subscribers with the opportunity to fund an HCFC-22 destruction project through the generation of A-Gas carbon credits to ensure the gas does not escape into the atmosphere. While the ACR (formerly American Carbon Registry) methodology has included HCFC-22 as eligible for destruction-generated offsets since 2017, few have completed such projects because the price of HCFC-22 is so high; it is more profitable for organizations to reclaim this product.  ACR’s methodology As such, this is one of the first HCFC-22 destruction projects utilizing ACR’s methodology. Approved by the International Civil Aviation Organization (ICAO) to provide carbon credits in its Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), ACR is highly regarded across the world.  Results  The partnership yielded multiple environmental benefits:   Emissions Avoided: The initiative successfully avoided the release of 16,000 tons of CO2-equivalent emissions by destroying HCFC-22. This substantial elimination of greenhouse gas emissions demonstrates the effectiveness of the program.   Subscriber Engagement: Wren provided its subscribers with detailed updates on the impact of their contributions. These updates included data on the quantities of HCFC-22 destroyed and the corresponding emissions reductions. This transparency helped build trust and encouraged ongoing participation in climate action.   Educational Impact: The collaboration raised awareness about the importance of proper lifecycle refrigerant management. Wren and A-Gas educated the public on lesser-known aspects of climate change mitigation by highlighting the environmental benefits of destroying high-GWP substances.   Conclusion  This partnership enabled an environmentally conscious solution for the used refrigerant By leveraging Wren's platform to mobilize individual contributions and A-Gas' technical expertise in lifecycle refrigerant management, this partnership enabled an environmentally conscious solution for the used refrigerant. It underscores the potential for innovative partnerships that can help to further reduce emissions in the refrigerant industry.  refrigerant destruction protocols and technology "We are excited to work with A-Gas to push forward the standard of refrigerant destruction protocols and technology," said Landon Brand, CEO, of Wren.
