Swedish heat pump manufacturer Qvantum has officially introduced its UK business, with invited guests attending the launch event at its new headquarters in Moorgate, London. Priding itself on being ‘more than just a heat pump manufacturer’, Qvantum’s ambition is to heat the cities of Europe using affordable renewable technology, alongside a commitment to generating positive change in electricity grid balancing. Unique heat pump solutions Qvantum UK CEO Phil Ord said: “We believe our unique heat pump solutions genuinely bring something new to the UK and can provide the impetus to redirect the way we consume energy to service the needs of the domestic heating and hot water market." “A big part of the challenge is to harvest and store renewable energy when it is plentiful, often in excess of what we actually need, and use it when demand increases above the generating capacity of the grid. Qvantum is here to help shift that peak.’’ Innovative line-up of solutions The innovative line-up of solutions includes: QE: exhaust air heat pumps (4kW/6kW) capable of providing heating, instantaneous domestic hot water and ventilation. As an added benefit, the QE is also able to provide a degree of cooling with a flow temperature of circa 18°C. This is not comfort cooling that can maintain a set room temperature but ‘overheat mitigation’ aiming to prevent adversely high temperatures and assist compliance with Part O. QG: a water-to-water, geothermal or ambient loop apartment heat pump system (6 kW/12 kW) supplying heating, cooling, and instantaneous domestic hot water for both single households with individual collectors as well as in ambient or low-temperature water loop applications. QA+QH-XL/QH-L: compact pre-plumbed hydro units used in conjunction with a Qvantum R290 (propane) monobloc air source unit (9 kW/15 kW). Qvantum heat pumps Thermal batteries have a capacity of up to 12 kWh and enable all Qvantum heat pumps to shift energy Qvantum’s business model has seen it invest heavily in technical and aftersales support personnel before product development, ensuring that the pain points of the heat pump and energy sectors have been identified before deciding how to address them and with what products. A modular design concept means that 80% of components are shared across the product line, including the unique integrated QH water tank shared across all three ranges, which is used as a thermal store and charged like a battery. The thermal batteries have a capacity of up to 12 kWh and enable all Qvantum heat pumps to shift energy consumption for heating and hot water away from peak periods, easing the load on electricity grids and reducing environmental impact through the time of use (ToU) shifting, in addition to considerable running cost saving for the property owner. Integrated thermal store The thermal store can be heated to high temperatures by the heat pump or an integrated immersion heater, consuming electricity when it is cheaper, in abundance, or produced during low carbon intensity.  Hot water is produced indirectly via a plate heat exchanger using energy from the thermal store, so the need for a legionella pasteurization cycle is removed. A property’s heating system can be served directly from the heat pump compressor module at any time or from the thermal store for peak load saving, or a mixture of both. cloud-based control solutions FLEXREADY®, an open API that enables 3rd-party cloud-based control keys to integrate with product line-up FLEXREADY® is an open API that enables third-party cloud-based control solutions to integrate with Qvantum’s product line-up. It is currently used to interrogate and monitor systems remotely connected via Wi-Fi, but when used more widely it will enable energy providers to charge hundreds of thousands of thermal stores on demand when the production of electricity outweighs its consumption. This will reduce the amount of time renewable energy generation is dormant because of grid capacity and lessen the reliance on fossil fuels to generate electricity during peak periods, simultaneously reducing the home’s running costs and carbon emissions. Qvantum’s products Qvantum’s products are backed by manufacturer-supported national service coverage from over 130 engineers. The products are installed and commissioned using dedicated apps that provide step-by-step guidance, data logging, installation and user manual access, and system registration.  A service app is accessible for system monitoring with actual operating data displayed alongside system schematics for easy understanding. Qvantum’s modular product concept Training is fed in-house with an online platform and face-to-face at Qvantum’s dedicated training room The Q-support remote monitoring service offers live data viewing and logs historical data, so service engineers can review it before attending the site, reducing first-fix repair times. Qvantum’s modular product concept also means that engineers can carry a reduced number of parts, knowing that 80% are interchangeable throughout the range. In addition, engineers who do not hold refrigerant-related qualifications can remove compressor modules by disconnecting hydronic connections only. Training is provided in-house with an online platform as well as face-to-face at Qvantum’s dedicated training room at its Moorgate offices. Training facilities and product line-up Guests at the launch were able to explore the training facilities and product line-up, following presentations from Phil Ord and Qvantum UK colleagues Darren Manley (Technical Sales Director) and Geoff Turton (Aftersales Technical Director).  Further background was provided by Thomas Nowak, former Secretary General of the European Heat Pump Association, who is now Qvantum’s VP of Government Relations and Public Affairs.

The indoor butterfly habitat at UK's Chester Zoo is a purpose-built space which is home to an array of butterflies, stream frogs, anoles and millipedes, mainly from South America and Southeast Asia. These species require a very warm environment, kept between 22°C and 25°C, whatever the weather outside in Cheshire. The habitat, which is 471 m2 and around 10 m at its widest part, was previously heated with a liquified petroleum gas (LPG) heating system but is now entirely heated by an air source heat pump system from Mitsubishi Electric. Reduce carbon emissions Chester Zoo, which is a world-pioneering conservation and education charity, has developed ambitious sustainability plans that will help the zoo reduce carbon emissions and achieve net zero: “Our mission is to prevent extinction and raise awareness of conservation and environmental challenges around the world, so we know that we can’t be part of the problem that we’re trying to solve,” explains Jennifer Kelly, Head of Sustainability at Chester Zoo. “That’s why we are looking to reduce our reliance on fossil fuel heating across our site, and why we are partnering with Mitsubishi Electric.” Ecodan air source heat pumps All the heating for the butterfly house is now provided by Ecodan air source heat pumps All the heating for the butterfly house is now provided from renewable Ecodan air source heat pumps – a sustainable heating technology. Seven heat pumps work in a cascade system to deliver a tropical environment that visitors can wander through as the butterflies free fly around them. “The zoo has a brilliant M&E project team who we have worked with to look at how we could apply heat pumps to the butterfly habitat,” explained Chris Newman, Net Zero Carbon Design Manager. “It’s part of the longer-term process of decarbonizing as much of the zoo as possible.” Carbon net zero Chester Zoo is aiming to be carbon net zero in its scope 1 and 2 emissions by 2030 and carbon net zero in its scope 3 emissions by 2050 at the latest. As part of this, it is actively working to reduce its reliance on fossil fuels across the 128-acre zoo site. As a not-for-profit organization, the zoo ploughs everything into its conservation mission, both in the UK and around the world and works with more than 3,000 species globally, including hundreds of international animal conservation breeding and habitat programs, which are ensuring the survival of species on the very brink of extinction. Experts from the zoo are recognized by governments and NGOs across the world as pioneers within the global conservation community.

For warehouse and factory owners, cutting their heat energy bills by over 90% might seem like a pipedream. I’ve been in enough warehouses to know one thing: heating them is expensive and frustrating. It often feels like throwing money into the wind. However, times are changing, and with the introduction of Shortwave Infrared (SWI), a revolutionary technology set to redefine warehouse heating, business owners can finally achieve energy savings on the scale they need.  Shortwave Infrared (SWI) For warehouse owners, slashing heat energy bills by more than 90% might sound far-fetched. Having spent time in countless warehouses, I know one thing: heating them is both costly and frustrating like throwing money into thin air.  But times are changing. With the arrival of Shortwave Infrared (SWI), a ground-breaking technology poised to transform warehouse heating, business owners can now achieve the substantial energy savings they've been seeking.  Beyond the Status Quo  Faced with soaring bills, warehouse, and factory owners are actively seeking better alternatives For years, warehouse heating has been stuck in a cycle of inefficiency opting for bulky systems that consume vast amounts of energy but offer little in return. High heating bills were once seen as an unavoidable cost of doing business. However, the energy price hikes of 2021 and 2022 completely changed the game, straining heating budgets and forcing a rethink of what's acceptable.  But there are positives to find in the situation. Faced with soaring bills, warehouse, and factory owners are actively seeking better alternatives.  Next-gen technology An industry long overdue for disruption has finally found the push it needed to embrace 'next-gen' technology. Enter Shortwave Infrared, ready to take the spotlight.  At the forefront of the heating revolution, it’s delivering unprecedented energy savings and cost efficiency, setting a new standard for businesses nationwide.  Lost in Translation  So, what sets SWI apart, and why does it outperform current systems? It all comes down to SWI's core heating principles. One of the most rewarding moments of my career was seeing the reaction of workers, shivering in a drafty space, suddenly feeling the warmth from SWI heaters. Their faces said it all – they couldn’t believe how something so simple could work so effectively.  However, the main issue is that currently, the warehouse and logistics sector largely depends on convection heating, which works by warming the air within a space. While this might be adequate for smaller, enclosed areas, it falls short in large, open-plan spaces where heat quickly dissipates.  Basic physics Turning up the thermostat won’t help either, as the principles are floored from the beginning It all comes down to basic physics, warm air rises. In buildings with high ceilings, this means heat drifts upwards, leaving workers on the ground cold, while the warmth stays out of reach. The issue is made worse by large doors and windows, which allow even more heat to escape.  For those lucky enough to be near a heater, it can be hit-or-miss. Turning up the thermostat won’t help either, as the principles are floored from the beginning. You’ll just be draining budgets quicker than before. SWI: A New Frontier  On the other hand, Shortwave Infrared Heating offers a revolutionary solution. By providing localized heat, it ensures workers stay comfortable and productive, regardless of the ambient temperature.​ Unlike traditional heating systems, SWI eliminates heat loss by targeting individuals directly – a feeling akin to the warm sun on your back. This strategic approach not only saves energy, but also creates a more comfortable workspace, making it an ideal solution for businesses seeking major efficiency and cost savings.  Cost and carbon savings Unlike convection heating, SWI also delivers consistent warmth, eliminating cold spots.  Additionally, its electric power source offers substantial cost and carbon savings, making it a sensible choice for those looking to align their heating systems with ESG initiatives.  The Verdict is In  By implementing SWIR, we helped them achieve a 90% reduction in energy consumption The good news is that the word is out, and companies are now reporting over 90% energy savings while drastically reducing their carbon footprints. A recent customer faced the challenge of heating a massive 5,000-square-meter space. By implementing SWIR, we helped them achieve a 90% reduction in energy consumption, exceeding expectations.  Annual energy consumption The numbers speak for themselves. Annual energy consumption dropped from 150,000 kWh (gas) to 16,000 kWh (electricity), showcasing the incredible potential for change in UK businesses. This is just one example, imagine what we can achieve rolling out SWI across the country,  The positive impact on the bottom line has prompted the company to implement SWI across all of its UK sites. As a sustainability-driven business, SWI provides a crucial solution to reduce reliance on carbon-heavy fossil fuels.  The Future is Bright  SWI's potential to transform warehouse and logistics is endless and businesses are now waking up to its potential, and are rightly being drawn in by the idea of significant cost and carbon savings. It’s a shift in mindset that’s challenging traditional heating methods. By focusing on precise, targeted warmth, rather than wasteful, resource-heavy convection heating, UK businesses are already saving millions of pounds each year.  Efficiency of infrared technological challenges Business owners are accustomed to thinking of heating as raising the overall temperature of a space Yet one of the biggest challenges the industry faces is a mental one, not a mechanical one. Business owners are accustomed to thinking of heating as raising the overall temperature of a space. However, this outdated approach fails to consider the efficiency of infrared technology, which delivers focused warmth directly to workers, equipment, or specific areas.  Impact of SWI I'm always thrilled to see the reactions of customers amazed by the impact of SWI. However, we need more people to embrace this innovative heating method, which means winning more hearts and minds.  For those ready to make the switch, the benefits will be substantial, potentially saving thousands, if not millions, on heating bills at a time when they need it most.

Data centers worldwide are under intense pressure. High-powered computing is a global necessity that seemingly gets more demanding by the day. There’s also the need to prioritize sustainability improvements ranging from resource conservation to decarbonization. And data centers must consider their bottom line and remain competitive. Anticipating the challenges data centers will continue to face, scientists and engineers have innovated two-phase (2-PIC) immersion cooling. With the capacity to meet the elevated cooling requirements driven by high-powered computing, this next-generation solution delivers on environmental priorities by significantly lowering data center energy consumption, slashing, if not eliminating, water use, while supporting decarbonization, circularity missions, and more. Emergence of 2-PIC Traditional approaches are fast approaching capacity for meeting current and future cooling needs The emergence of 2-PIC comes at a critical time, because the traditional cooling methods that have kept data centers up and running so far—namely air cooling and water cooling—are doing so at the detriment of the planet.  Additionally, these traditional approaches are quickly approaching capacity for meeting current and future cooling needs. Air- and water-cooling methods are used in approximately 95% of the estimated 8,000 data centers that exist today. The criticality of high-powered computing Once seen as a future need, high-powered computing, and faster-than-ever processing are now established as critical to the operation of businesses, governments, organizations, and other entities that support the way communities function, survive, and thrive. Whether it’s health and wellness, financial institutions, economic growth, safety and protection, entertainment, education, or any other service supporting our way of life, successfully providing that service fully depends on the ability of data centers to quickly and reliably obtain, store, and process data.  Influence of AI AI has a profound influence and, generates far more power than traditional internet uses Moreover, when we say “data centers,” we’re not just speaking of big players like Microsoft, Google, Meta, and Amazon. Equally dependent on high-performance, high-speed computing are enterprise data center operators, such as our governments and military, financial institutions, healthcare systems, educational institutions, and more.  We also must acknowledge the profound influence of artificial intelligence (AI), which generates far more power than traditional internet uses. Its effects are far-reaching, enhancing patient care, supporting risk management and fraud detection in finance, boosting crop yields within agriculture, and more. The environmental costs of data centers According to the latest estimates by the International Energy Agency, data centers worldwide produce 1% of energy-related carbon emissions and in 2022 used approximately 460 TWh of electricity per year—equating to 2% of global electricity demand. McKinsey and Company estimates 40% of this electricity is used for data center cooling. Data centers’ impact on the environment also includes their significant water consumption, averaging 300,000 gallons per day, and a physical footprint that averages 100,000 square feet but in the case of some hyperscale data centers can range between 1.3 to 2 million square feet. In terms of growth, a U.S. market report from Newmark tells us that in the U.S. alone, the U.S. data center footprint will absorb 35 gigawatts by 2030, which is more than twice the data center power consumption of 2022. The emergence of liquid cooling: the elevated interest in 2-PIC From reducing energy and water consumption to shrinking physical footprints, 2-PIC offers the planet a better data center solution. In less than two years, traditional cooling systems won’t be able to support the exponential growth in the world’s data processing and storage applications. Based on publicly available product roadmaps from major chip manufacturers, by 2026, air-cooled systems will no longer be able to meet the cooling needs of most next-generation, high-performance computing chips. Capable of removing heat more effectively than air cooling, liquid cooling uses a liquid such as water or a dielectric fluid to cool the heat-generating components of servers. The liquid can cool these components directly, or it can be done indirectly through a heat exchanger. With two-phase immersion cooling the entire server rack is submerged in a tank filled with a dielectric fluid. Single-phase and two-phase liquid cooling Single-phase liquid cooling uses a pump to circulate the liquid through a closed-loop system Single-phase liquid cooling uses a pump to circulate the liquid through a closed-loop system. Two-phase liquid cooling uses a phase-change material, such as a refrigerant, which evaporates and condenses as it absorbs and releases heat. With 2-PIC, which is a form of two-phase liquid cooling, the entire server rack is submerged in a tank filled with dielectric fluid. The fluid boils as it’s heated by the components of the servers, creating bubbles that rise to the surface and condense in a heat exchanger. Gravity then returns the condensed fluid to the tank, creating a natural circulation loop that does not require pumps or fans. Advantages of 2-PIC 2-PIC is commanding attention as the solution for meeting the cooling demands of the high-powered computing components of today and tomorrow. Moreover, the technology of 2-PIC systems, combined with the right dielectric fluid, delivers advantages to “take the heat off” data centers. Here’s a breakdown of additional 2-PIC benefits: Up to 90% reduction in energy consumption: Based on modeling completed by the industry, 2-PIC is expected to reduce up to 90% of data center cooling energy consumption and 40% of overall data center energy consumption*. (*Compared to traditional air-cooling technologies) Enhanced computing performance and data center reliability: 2-PIC allows servers to operate at higher temperatures and power densities, while reducing the risk of overheating. Significant reduction in water consumption: Depending on the data center location and cooling design methodology, water consumption could even be eliminated completely. 60% reduction in the physical footprint: 2-PIC reduces the space required for cooling equipment, freeing up more floor area for servers and increasing the rack density of the data center. Lower GWP and circularity: Chemours Opteon™ 2P50 is a developmental dielectric heat-transfer fluid, currently pre-commercial, pending regulatory approval. It offers an extremely low global warming potential (GWP) of 10 and was specifically created to optimize the performance of the electronic components in a 2-PIC system. This 2-PIC fluid also enables the reprocessing/reuse of existing fluid to maximize circularity.  The bottom line: In addition to other compelling data, a recent study commissioned by Chemours and LiquidStack through Syska Hennessy, revealed that, compared with other state-of-the-art liquid cooling methods, 2-PIC can deliver up to a 40% lower total cost of ownership (TCO) and significantly reduce operational expenditures (OPEX), with savings ranging from 54% to 88.6%. Benefits of new data center cooling technologies compared to single-phase direct-to-chip, and single-phase immersion methods. 2-PIC, the future-ready solution As the world’s reliance on AI and other high-powered computing capabilities escalates, data center cooling solutions must grow with demand while significantly reducing their impact on the environment. In global energy savings alone, 2-PIC could generate an estimated savings of 340 TWh by 2055—the equivalent of powering more than 517 million laptops 24/7. And even with increasing IT loads, 2-PIC maintains its performance, ensuring long-term cost-effectiveness and adaptability to meet future demands. With society at a crossroads between the criticality of high-powered computing and a planet in crisis, the industry is turning its attention to 2-PIC as the solution for today and tomorrow.

The HVAC market is forecasted to grow at a projected compound annual growth rate (CAGR) of 3.9%, with a prediction to reach $370 billion by 2030. But in reality, the HVAC and plumbing industry is changing rapidly, with operators facing new challenges like never before. Whether it’s rising costs, the uncertain economy, increasing competition, or the workforce shortage, there’s no doubt the HVAC and plumbing market is evolving. So how do you adapt? That’s the key question. My take is that we can’t predict the future, but we can adjust based on the facts on the field. That’s why now is the time for industry operators to focus on strategies that elevate growth, relationships, and longevity. Here are three ways to tackle today’s market. 1. Diversify Service Offerings With the rising costs of customer acquisition and market competitiveness, it is increasingly challenging to build a successful, resilient trade business by just offering one service — especially if it’s a seasonal specialty. While one-service shops were the norm historically, things have changed in the market. The contractor’s relationship with the customer has never been more valuable, and offering multiple trades allows operators to keep relationships within the four walls of the company – without referring valuable leads (or the potential to lose a customer entirely) to the competition. While one-service shops were the norm historically, things have changed in the market By adding more services to your HVAC and plumbing line-up, you become the one-stop, go-to source for essential home services in your market. For the long-term sustainability of the business, it is crucial to ultimately offer the essential three services: electrical, plumbing/sewer, and HVAC. Additionally, when you provide a variety of services your business will experience less seasonal or cyclical highs & lows because it’s well-rounded, diverse, and, ultimately, healthy. 2. Build Scale through Investment It’s a fact: The home services market is highly fragmented, with over 100,000 contracting businesses active in the United States. It also continues to churn out profits — making it a quality investment for home services investors and private equity sponsors. The fragmented market dynamic is an ideal opportunity for consolidation – and there is more investment capital flowing into the market than ever before. Owners with ambitions to grow can be aggressive with tuck-in acquisitions to offer differentiated services Nationally, scaled Platforms backed by investors or large franchisors service ~20% of the market in a metro area. The benefits of scale are significant: substantial purchasing power (especially on equipment), robust digital/traditional marketing capabilities, programmatic recruiting/training functions, breadth of service offerings, and robust balance sheet to fund growth and investment – just to name a few. However, not every investor is the same. Many employ business practices inconsistent with the culture of founder/owner-backed businesses, which smart entrepreneurs/operators can use to their advantage. Owners with ambitions to grow can be aggressive with tuck-in acquisitions to offer differentiated services and build breadth/new skills in their businesses. Alternatively, businesses struggling to make it on their own or with owners approaching retirement, can partner with larger service providers so they can keep practicing their trade without having to run the day-to-day business – just be careful with selecting the right investor to protect your people and legacy. 3. React in Real Time One thing the HVAC and plumbing industry has proven over the last few years is its resilience – especially for the best operators. No matter what the economic climate is, homeowners still need to protect and stay comfortable in their most valuable asset. That should provide a sense of job security to HVAC and plumbing professionals — but also motivate you to go the extra mile to attract and retain business. Just because the HVAC and plumbing industry has shown signs of being recession-resistant (for now) does not mean it can’t be impacted by the economy. That’s why it’s crucial to manage the business daily – especially pricing and the components of gross margin. The best operators review cost inputs with their teams weekly and adjust mid-month, which ultimately helps the business maintain its health and profitability. As we head into the back half of 2024, it will be interesting to see how the rest of the year plays out for the industry, and I continue to be optimistic about a bounce back after a tough 2023. We will have to wait and see-but with the strategies above, businesses can position for success no matter what happens in the future.

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?##}

SNAP Rule 26 marks an important milestone in the transition from commercial refrigeration to new refrigerants. The rule lists refrigerant substitutes that provide a spectrum of technological solutions to meet required performance, global warming potential (GWP), safety, and environmental standards.  SNAP stands for Significant New Alternatives Policy, a program by the U.S. EPA (Environmental Protection Agency) under the Clean Air Act. In general, the program aims to evaluate and regulate substitutes for ozone-depleting substances, considering their overall risks to both human health and the environment. Impact of SNAP Rule 26 Final SNAP Rule 26, Protection of Stratospheric Ozone, lists acceptable substitutes in commercial and industrial refrigeration. SNAP Rule 26 will be effective July 15, 2024. The incorporation by reference of certain material listed in the rule is approved by the Director of the Federal Register as of July 15, 2024. The incorporation by reference of certain material listed in the rule is approved by the Director of the Federal Register “To date, the SNAP program has provided a very effective framework for evaluation and approval in support of innovation and the transition to new technology,” says Andrew Pansulla, Technical Service Engineer, The Chemours Company, a global chemistry company that provides a range of refrigerant products. We asked Pansulla to elaborate further on the impact of SNAP Rule 26 and what lies ahead. Q: How will the Rule’s finalization impact various commercial refrigeration sectors? Pansulla: The rule’s finalization will impact commercial refrigeration in several ways. Areas, where impact will likely be seen, include providing more acceptable refrigerant options, adherence to updated standards, new equipment design standards, and the exemption of propane from the venting prohibition for refrigerated food processing and dispensing equipment. These impacts could trigger changes in operational, manufacturing, and environmental compliance strategies in the commercial refrigeration sectors. SNAP Rule 26 will enable the adoption of the listed substitutes, including Chemours Opteon™ refrigerants, with global warming potential (GWP) lower than existing refrigerants. This rule does not require any changes to existing equipment and will impact only new equipment that uses the specific substances referenced in the SNAP rule. Q: What is the outlook for additional requirements for safe handling and use of alternative refrigerants? What specific safety standards are expected or appropriate? Pansulla: As part of the comparative risk framework used by the EPA to assess new alternatives, the EPA considers and implements use conditions that will ensure the safe use of products. These use conditions rely upon existing safety standards (e.g., UL and ASHRAE) which are available at the time the rule is finalized. In the case of SNAP Rule 26, many of the use conditions require adherence to UL 60335-2-89 and ASHRAE-15-2022. These standards are reviewed and updated periodically to maintain relevance with the products subject to the standards. Q: What are any limitations of the use of A2L refrigerants under SNAP Rule 26? Pansulla: There are two main categories of limitations under SNAP Rule 26. The first, as mentioned above, is the adherence to specific safety standards that apply to refrigerants that are designated as mildly flammable (A2L). The second is based on the GWP of the refrigerant. In the case of the A2L refrigerants subject to SNAP Rule 26, the EPA imposed conditions on the type of equipment and specific circumstances in which the substitute may be used. For example, the EPA is permitting the use of R-454A in supermarket systems, but only on the high side of a cascade system, or when the refrigerant charge capacity is less than 200 pounds. Q: Which new-generation A2L refrigerants are fit for which commercial refrigeration applications? Pansulla: Under SNAP Rule 26, the EPA deems R-1234yf, R-1234ze(E), R-454C, R-455A, R-457A, and R-516A as acceptable subject-to-use conditions for various commercial refrigeration applications. This selection is primarily driven by these refrigerants having GWPs under 150. However, certain applications necessitate refrigerants with higher GWPs due to unique performance characteristics. For example, R-454B and R-32 were listed for industrial process refrigeration with exiting fluid temperatures below minus 30 degree Celsius because these two specific refrigerants have lower boiling points than the other six less-than-150-GWP alternatives. However, it is critically important to consider the additional use conditions when designing equipment with refrigerants that have a GWP greater than 150. Q: So various equipment needs different refrigerants? Pansulla: The EPA purposefully lists several different refrigerants in each application to allow for equipment manufacturers to consider a variety of different factors that go into refrigerant selection, such as energy efficiency, capacity, normal boiling point, temperature glide, cost, safety, and use conditions. There is no one-size-fits-all solution for the entire commercial refrigeration industry. Q: How can commercial refrigeration businesses achieve a smooth transition to A2Ls? Pansulla: Keys to a smooth transition to A2Ls include understanding what refrigerants the EPA has approved as acceptable substitutes under the SNAP program, the sector-based GWP limits imposed by the Technology Transitions Program under the American Innovation and Manufacturing (AIM) Act, and which refrigerants provide the best combination of technical performance and environmental characteristics. Many resources are available to navigate the regulatory landscape and select the best low-GWP refrigerants to meet the needs of this industry. Working with companies like Chemours, who has nearly a century of refrigerant innovation and experience, is a great first step in the transition process. Q: What is the “staying power” of A2Ls — based on their chemistry, sustainability, and other attributes, combined with regulations such as SNAP Rule 26? Pansulla: The identification, selection, and development of new refrigerants that deliver required performance while meeting increasingly stringent environmental standards is a challenging process. With the identification of certain hydrofluoroolefin-based (HFO) refrigerants as an alternative to meet these criteria came a new safety classification. These HFO-based refrigerants are classified as A2Ls. While slightly more flammable than existing hydrofluorocarbon-base (HFC) refrigerants, HFOs are much less flammable than hydrocarbons, which are classified as A3 (two categories higher on the ASHRAE flammability spectrum). Moreover, such refrigerants offer an excellent alternative to substances with higher toxicity, such as R-717. The listing of A2L refrigerants in SNAP Rule 26 clearly indicates that such refrigerants can be used safely in commercial refrigeration as well as many other applications, which are subject to the SNAP Program, when adhering to the applicable safety standards.

It takes a proliferation of data centers to serve the growing computing needs of the Internet, and all those servers churning away create plenty of heat. Might some of that heat be harnessed and used for residential or commercial heating? The emergence of district heating systems, which provide thermal energy to multiple buildings from a single source, demonstrates the approach has broad possibilities. Air-cooled chillers and air-handling units used to cool data centers are like the technologies that cool residences and businesses. They just operate on a larger scale and require a higher degree of resilience and redundancy to ensure data center servers operate without interruption. District heating system The law of physics dictates that the energy you put into a data server will come out as heat, and heat is a byproduct of data center cooling systems. Rather than exhaust that heat into the outside environment, how can it be captured and channeled into a district heating system to heat water and/or to provide warmth to homes and businesses in the same neighborhood as the data center? Law of physics dictates that the energy you put into a data server will come out as heat  Mitsubishi Electric designs engineered solutions that both cool data centers and generate heat output that can be captured for district heating applications. “We want to capture the heat and repurpose it for someone else to use,” says Simon Prichard, Product Strategy Manager for Engineered Solutions for Mitsubishi Electric. Reusing wasted heat from data centers can help to decarbonize heating. United Kingdom's Energy Act 2023 An additional heat pump can be used to increase the “low-grade heat” generated by a data center to the temperature needed for district heating. Alternatively, district heating systems might be upgraded to accommodate the lower-temperature heat from data centers. Additional heat pump can be used to increase the “low-grade heat” generated by a data center. The United Kingdom and other governments globally are promoting the creation of district heating networks. Legislation such as the United Kingdom's Energy Act 2023 identifies areas within England where certain new and existing buildings will be required to connect into district heating networks. Legislation is pushing developers toward district heating and away from the use of fossil fuels. District heating applications Water cooling is a developing technology for data centers, which mostly use air-cooling systems In November 2023, the UK government awarded £36 million to a district heating system in West London that will share data center waste heat with up to 10,000 new homes. Hot air from a data center can provide some of the energy needed for a district heating system, and water-cooling systems can provide even more. Water cooling is a developing technology for data centers, which mostly use air cooling systems. Cooperation is needed to realize the scenario of capturing the heat from data centers for district heating applications. Government legislation can drive requirements to embrace the approach, but the multiple involved parties, including data center operators and the architects and engineers creating nearby communities, must also cooperate. Greater ESG goals Energy must be reused in the geographic area immediately surrounding the data center for the scenario to be financially viable. In an industrial estate, for example, the excess heat could be used for nearby farming; the reuse is not restricted to domestic or residential applications. The various parties tend to be “siloed,” so a concerted effort of “joined-up thinking” is needed to bring all the parties to the table to enable such a system. Construction of new data centers is accelerating, and the centers are getting larger. Construction of new data centers is accelerating, and the centers are getting larger. Currently, 4 or 5% of total electricity output is used by data centers, and ways to reuse that energy are a growing priority for ethical companies in the data center market. Large companies that use data centers are drawn to the district heating scenario to achieve greater ESG (Environmental, Social, and Governance) goals. Moving forward, it behooves everyone to think of data centers as not just generating data but as energy centers generating sustainable energy. Mitsubishi Electric’s products MEWALL mixes high version with energy efficiency, space optimization, and cost-effectiveness “We live in a connected world, and we need data centers,” says Prichard. “The world won’t work without them, but many people don’t know what a data center is and how much we rely on them. Society doesn’t realize how embedded they are.” Among Mitsubishi Electric’s products for the data center market is the MEWALL air handling unit, a “wall” of fans with built-in controls, valves, and filters that are mounted alongside a suite of data servers. MEWALL combines high performance with energy efficiency, space optimization, and cost-effectiveness. Water circulates inside the fans, using cold water produced by a chiller. View of the MEWALL system Smaller data center needs can be addressed using technology such as Mitsubishi Electric’s indoor s-MEXT high-precision air conditioner connected to a Mr. Slim R32 Power Inverter outdoor unit. The indoor unit is customized to the client’s requirements for use in a data center.  At the Data Center World trade show in London in March, Mitsubishi Electric used virtual reality (VR) to provide attendees with a simulated view of the MEWALL system. Given the dimensions of 4 by 2.3 meters, transporting the system to the show presented prohibitive cost and logistical challenges.

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.

When Harry Lau, Administrator for Facilities and Operations for the Livonia Public Schools, joined the district in 2013, he identified a significant need to improve the HVAC equipment throughout the entire school system. All 25 buildings, including schools and administration offices, had significant inefficiencies with their HVAC systems. The infrastructure was outdated and the horizontal unit ventilators that were in use were from the 1950s and 60s and were well beyond their life expectancy. The old units were prone to freezing, and there were control issues that further exacerbated the problem. Poor indoor air quality (IAQ) and inefficient temperature controls led to discomfort among staff and students, impacting the overall learning environment. His primary goal was to reduce the number of environmental air quality concerns, reduce district utility and maintenance costs, and improve the overall comfort and air quality throughout the system. The Solution To address these issues, Livonia Public Schools secured funds via a successful bond measure To address these issues, Livonia Public Schools secured funds through a successful bond measure. There were multiple contractors and manufacturers involved for the entire system upgrade, but for the classrooms specifically, the district chose to upgrade to Airedale by Modine Classmate® vertical units. Looking at the specifications of these units, Harry was certain the Classmate® would meet their needs.  The previous units had structural and design issues that led to multiple repairs, and Harry knew that they would have fewer maintenance issues with the Classmate® because of the way they are designed. They also chose to modernize control of the system by implementing a building management system allowing for real-time monitoring and centralized management of the HVAC systems across all buildings. The Results The HVAC system upgrades have resulted in dramatic improvements in IAQ and energy efficiency. The new systems have provided better temperature control, faster cooling, and heating, and have reduced energy consumption by 20%. The upgraded systems also led to a quieter environment, enhancing the learning experience. The ability to monitor and manage the HVAC systems in real time has allowed for proactive maintenance and further cost savings. Harry said he wanted the classroom instructors to have some anonymity with temperature control. While the set points follow ASHRAE recommendations, the units are equipped to give the teachers some control to bump the temperature up or down a few degrees to suit their comfort level and those of the students.  "With partners like Modine, they opened our eyes on ways of doing things," said Harry Lau, adding "It has been refreshing to actually be heard by the professionals." Implementation of HVAC upgrades Livonia Public Schools has been recognized by the U.S. DOE’s Efficient and Healthy Schools Program Because of their commitment to improving IAQ and energy efficiency, Livonia Public Schools has been recognized by the U.S. Department of Energy’s Efficient and Healthy Schools Program. This program recognizes and assists school districts seeking to implement high-impact indoor air quality and efficiency improvements. They were honored for optimizing their operations to improve building performance. The district was also recognized by the city as a green energy partner. Harry said that the classroom learning environments have been dramatically updated and they have seen a significant improvement. The consistent modulation of the fresh air has been greatly noticed. Livonia Public Schools’ proactive approach to HVAC upgrades A huge point of pride for the district was being able to confidently inform their staff and parents that they were ahead of the curve in ensuring quality indoor air once students and staff were able to return to indoor classroom learning during the COVID-19 pandemic.  Livonia Public Schools’ proactive approach and successful implementation of HVAC upgrades have set a benchmark for other districts aiming to improve their learning environments through better air quality and energy efficiency.

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.”

Kepier School's phased transition to low-carbon CIAT heating technologies has delivered generous energy savings within a year of installation. CIAT worked with partners to initiate the school’s journey to net zero in 2022, returning to measure performance and optimize the system. CIAT is a part of Carrier Global Corporation, a global pioneer in intelligent climate and energy solutions. New high-efficiency heat emitters CIAT worked with BREng Hull Ltd, AA Projects, Quora Group, and Cool Designs Ltd to create a phased decarbonization plan for Kepier School in Northeast England, aided by the Condition Improvement Fund (CIF). Recognizing the challenges faced by many schools, Oliver Sanders, Carrier Commercial HVAC Director, United Kingdom, and Ireland, said, "For schools with new gas boilers aiming to reach net zero, it's most cost-effective to integrate them into a modernized heating infrastructure, ready for the next transition phase to heat pumps when the boilers reach end-of-life." Project featured a heating audit The project involved a heating audit identifying the need for new high-efficiency heat emitters The project involved a heating audit identifying the need for new high-efficiency heat emitters. Conventional radiators were replaced with seven surface-mounted high-level CIAT MajorLine and 31 CIAT COADIS fan coil units (FCUs). The seven gas boilers installed in 2019 were integrated into the new system's infrastructure, enabling them to be replaced as required to improve system efficiency and cost savings. Sizeable energy savings A subsequent review revealed sizeable energy savings. Gas usage was compared before and after the pandemic to avoid skewed data due to COVID-19 school closures. Findings revealed an 8.6% reduction of 2,824 m3 (~31,446.41 kWhr) from March 2022 to March 2023 compared to the period from March 2019 to March 2020. This achievement reduced the school’s carbon footprint and resulted in an 8% annual cost saving of ~£800 (average based on gas price fluctuations between March 2019-2020 and March 2022-2023). CIAT project partners BREng Hull  CIAT project partners BREng Hull and installer Quora Group returned to the school to optimize system operating gains Following commission, CIAT project partners BREng Hull and installer Quora Group returned to the school to optimize system operating gains.  "The process doesn’t stop once a solution has been designed, installed, and commissioned," said Rob Smelt, Managing Director of BREng Hull, adding "Experience shows that there are often significant additional gains to be made by optimizing the system in light of its real-world operation." The inspection revealed that some areas were imbalanced while others operated at sub-optimal temperatures. These issues were addressed to improve occupant comfort and reduce energy use and running costs. Carrier’s 2030 ESG Goal "The comfort level has improved significantly," said Brian Dixon, Kepier School Estates Manager, adding "We already gained control over specific rooms and areas, as opposed to the old ‘on or off’ heating system, and the latest work seems to have improved things even more. Future phases in our decarbonization plan will yield even greater energy and cost savings for the school." BREng Hull worked closely with equipment supplier Cool Designs Ltd during the scoping and specification stages, supported by CIAT application specialists.

When the Florida Keys Aqueduct Authority opens its upgraded desalination plant on Stock Island, Danfoss high-pressure pumps and energy recovery devices will radically improve the energy efficiency of a SWRO plant that plays a central role in the Florida Keys water supply strategy.   The Florida Keys Aqueduct Authority (FKAA) supplies 20 million gallons of potable water per day (75.7k m3/d) to its nearly 80,000 customers in the Florida Keys. While most of the water is normally sourced in aquifers, FKAA also operates two seawater reverse osmosis (SWRO) plants for emergency purposes and as a supplemental supply in periods of high demand. FKAA initiated the SWRO plant upgrade FKAA initiated the upgrade of one of these plants, the Kermit H. Lewin Water Treatment Plant located on Stock Island, to increase its capacity, make it more resilient to hurricanes and rising flood levels, and improve its energy efficiency. Since opening in 1980, not only have guidelines for storm protection of such critical infrastructure changed significantly, so has the potential to save on the energy required by desalination. Designed to withstand future floods and hurricanes With sustained winds above 157 mph, such storms can cause severe damage to everything in their path To improve resiliency to extreme weather events in the low-lying Florida Keys, the entire site and facility have now been upgraded to withstand Category 5 hurricanes, the most dangerous level of tropical storms. With sustained winds above 157 mph (252 kph), such storms can cause severe damage to everything in their path. Accordingly, the refurbished facility lifts all electrical and mechanical equipment above the base flood elevation and the expected sea-level rise anticipated by 2060, effectively placing the plant’s desalination operations on stilts to mitigate the risk of severe flooding. improve the plant’s energy efficiency Another key goal of the upgrade was to improve the plant’s energy efficiency at the same time as doubling its production capacity from 2 MGD (7,500 m3/d) to 4 MGD (15,000 m3/d). To bring the refurbished plant up to date and reduce its financial and environmental costs, Carollo, a major U.S. engineering firm specializing in water and wastewater facilities, specified the latest axial-piston high-pressure pumps to replace legacy centrifugal pumps and swapped out old turbines for the newest active isobaric energy recovery technology. Upgraded plant to consist of four RO trains This innovative high-pressure setup dramatically reduces the plant’s energy needs This innovative high-pressure setup dramatically reduces the plant’s energy needs. In the new Kermit H. Lewin Water Treatment Plant being built by Biwater, a world pioneer in water treatment, the RO process-specific energy consumption will be slashed from 25.6 kW/kgal (6.77 kWh/m3) to 8.6 kW/kgal (2.27 kWh/m3). With this improvement, the new plant will be among the most energy-efficient in its class, with significantly reduced electricity bills and greenhouse gas emissions. The upgraded plant will consist of four RO trains, each of which includes two Danfoss APP 86 high-pressure pumps and three Danfoss iSave 70 ERDs. Improvement in energy efficiency In addition to the dramatic improvement in energy efficiency, configuring each train with parallel high-pressure pumps provides additional resilience and other benefits: the smaller pumps are easier to lift and work on, and it is now affordable to keep a spare pump in stock. The new improved plant will come online in Q4 2024. The new Kermit H. Lewin Water Treatment Plant is located just north of the existing plant. Construction began in Q3 2021 and will be completed by Q2 2024. The plant is expected to be fully operational by Q4 2024.

With nearly nine out of ten new school sites above the World Health Organization (WHO) targets on major air pollutants, Elta is urging decision makers for schools’ building services to address the problem through a ‘three-step’ process to ventilation specification and maintenance. The callout follows a study led by researchers from Evelina London Children’s Hospital and King’s College London (KCL). Following their analysis of 147 new school locations around England that were to be built between 2017 and 2025, the researchers found that 86% of those sites exceeded air quality targets. Those targets are for particulate matter PM2.5, PM10, and NO2 (Nitrogen Dioxide), pioneering to the conclusion that air quality around new schools is “alarmingly poor”. Three steps to prevent poor air  With emerging studies also showing that poor air quality leads to lowered cognitive growth With emerging studies also showing that poor air quality leads to lowered cognitive growth, Elta, UK’s pioneering experts in ventilation equipment, outlines three measures to tackle the problem. The three steps are aimed at preventing poor air from entering the school building and classrooms, including: Installing air monitoring equipment in schools to identify concentrations of particulate matter, nitrogen dioxide, and other contributors to poor air quality Using correctly specified mechanical ventilation systems to process and filter air of harmful particulate matter and substances, to bring indoor air quality to a safe level Having a robust maintenance schedule in place to clean ventilation equipment on a regular basis Decision-makers for building services David Millward, Group Product Manager at Elta Group, the parent company of Elta, said: “This latest study by Evelina London Children’s Hospital and King’s College London is a harsh wake-up call to everybody in the country and is a reminder that poor air quality has a real detrimental effect on children. Not only is it harmful from a health perspective, putting pupils with respiratory conditions like asthma at higher risk, but poor air also impairs children’s learning and ability to concentrate. “While outdoor air is hard to regulate, there are some immediate steps that decision-makers for building services can take to improve indoor air quality in schools. Through three simple steps of air quality monitoring, correct specification of mechanical ventilation systems, and regular maintenance of these systems, we can at least prevent poor air from making its way into the classroom.” Framework for ventilation Framework for ventilation in schools and recommended performance levels to comply with UK regulations David highlights that ‘Approved Document F – Ventilation – Volume 2’ of the Building Regulations gives guidance about air quality monitoring requirements in buildings other than dwellings.  Meanwhile, ventilation decision-makers for schools should follow the guidance given in the UK Government’s Building Bulletin, BB 101, to understand the framework for ventilation in schools and recommended performance levels to comply with UK regulations. David also urges those in charge of building services for schools to collaborate with ventilation experts to ensure best practices and compliance is achieved. Effects of poor air quality David concluded: “With better collaboration across the supply chain, we can protect the next generation from the effects of poor air quality, and improve indoor air quality across new schools, as well as old." "At Elta, our ventilation experts are always available to help provide guidance and help design ventilation systems, either for newly built schools or for retrofitting to existing school stock.”

The HVAC market is a rapidly changing environment on a variety of fronts, from the introduction of new refrigerants to the increasing use of artificial intelligence to the embrace of interconnected systems in the Internet of Things (IoT) environment. We asked our Expert Panel Roundtable: How will the HVAC market change in the next five years?

Multiple components work together to make an HVAC system run smoothly and efficiently. One of the newer components in today’s systems is data, whether it is information about historic performance trends or the weather outside. A variety of sensors work together to provide data that can be crunched by various algorithms to provide useful information to system installers and end-users, and to help systems run better and longer. We asked our Expert Panel Roundtable: How can data analytics be used to enhance HVAC solutions?

For schools, improving indoor air quality (IAQ) is a basic function of HVAC systems, which also ensures a high comfort level for students, teachers and staff. Schools can be a lucrative market for HVAC systems, but there are challenges, such as long sales cycles and the lingering impact of the COVID-19 pandemic.
