Expert Commentary
From temperate climates that reach mid-90 F in June and mild winters allowing people to be outdoors without jackets to the “May flowers” that bloom in early March, it’s evident that society is experiencing World Refrigeration Day’s 2024 theme: “Temperature matters.” In addition to driving climate change, global warming is driving changes in how people live and how industries adapt and innovate to support new dynamics. This is especially true for the HVACR Industry. Over the past several years, contractors have been busy installing and servicing cooling systems in climate zones that historically haven’t needed them. There’s a major focus on achieving more energy efficiency and lower water consumption in cooling the world’s escalating number of data centers. Impact on HVACR Industry There’s also increased demand to conserve water in cooling towers and/or adiabatic condensers and for elevated indoor environmental quality (IEQ) to improve health and productivity. A few examples show how rising global temperatures are impacting the HVACR industry These few examples demonstrate how rising global temperatures are impacting the HVACR industry. Sharing a huge part of the spotlight of industry solutions are refrigerants, which now need to work harder than ever to keep people comfortable and foods, beverages, and pharmaceuticals at proper temperatures. And they must do so without contributing to global warming and other environmental concerns. Refrigerant priority #1: lower GWP Assessing refrigerants for their ability to address climate change concerns starts with their global warming potential (GWP). That’s why attention has turned to A2Ls, which offer significantly lower GWP than legacy refrigerants. The three “big players” in the A2L arena—R-454A, R-454B, and R-454C—are now being selected for new-generation equipment solutions in various HVACR applications. A look at GWP reduction in a sampling of these applications tells the story: R-454A and R-454C can provide a 94% to 96% reduction in GWP as an alternative for R-404A, while offering similar performance Applications that historically would use a new R-410A unit can transition to R-454B, resulting in a 77% reduction in GWP. The industry is also choosing HFO-1234yf, an A2L currently used in air conditioners in 95 million vehicles on U.S. roads. HFO-1234yf has an AR4 GWP of 4 and is also used as a blend component in Chemours A1 and A2L products. Although A2Ls are for new equipment only, lower-GWP A1 refrigerant solutions can help in retrofits. For most applications using a higher-GWP HFC in an existing system, there’s likely a lower-GWP HFC/HFO blend for retrofit applications Other refrigerant priorities Of course, the value of a refrigerant is based on more than just low GWP Of course, the value of a refrigerant is based on more than just low GWP. The true innovation in refrigerant development lies in striking the optimal balance between environmental impact and performance for a diversity of applications. For example, after developing what are now considered three major players in the future of refrigerants—Chemours Opteon™ XL40 (R-454A), Opteon™ XL41 (R-454B), and Opteon™ XL20 (R-454C)—our chemists remain in the labs and work with pioneering industry partners to lower GWP even more, without compromising other properties. It’s important to consider how well a refrigerant addresses several key factors: Low GWP and zero ozone depletion potential (ODP) Reduced energy consumption Circularity—the ability to be recovered, recycled, and reclaimed Lower operating costs over the lifetime of equipment Safety—for everyone from technicians to end users Overall performance—measured by capacity, reliability, and efficiency Can be serviced by a large existing workforce of trained technicians Responsible manufacturing focused on reducing carbon emissions Availability and supply chain strength A2L refrigerants have been designed with these factors in mind, raising the bar in terms of performance and support for environmental priorities. Addressing climate zone challenges In addition to solutions designed for today’s many residential, commercial, and industrial cooling and refrigeration applications, the industry needs a full toolbox of systems, components, and refrigerants to meet—in a highly efficient manner—the challenges of cooling and heating in various climate zones. These range from Zone 1, which is very hot, humid, and dry, to the subarctic Zone 8 ASHRAE divides the U.S. into eight major climate zones. These range from Zone 1, which is very hot, humid, and dry, to the subarctic Zone 8. In between these two extremes, we find various levels of heat/cold, humidity, and dryness. These climate zones provide system engineers with guidance for choosing the best designs—including refrigerant selection—so that each zone can be equipped with the appropriate system, optimized for year-round capacity, efficiency, reliability, and more. New-generation heat pumps For example, the high heat and humidity of a tropical climate put heavy demand on cooling equipment—from air conditioners to refrigeration systems. These cooling systems are likely to run most of the year, so choosing a highly energy-efficient option is paramount. By contrast, we have zones with overall colder ambient temperatures. Heat pumps must be properly sized to ensure occupant comfort. Cooling systems in these climates have limited use during the year, but they must perform reliably when needed. In climates where heating buildings take priority over cooling them, we’re finding a significant transition from traditional AC-only units to new-generation heat pumps. Heat pumps must be properly sized to ensure occupant comfort and keep the heat pump from “struggling” to control humidity when operated in AC mode. Choosing refrigerant solutions There is no question the world’s temperature is on the rise. According to the National Oceanic and Atmospheric Administration, since 1982, the rate of the Earth’s warming has risen approximately 0.36 F (0.20°C) per decade—more than three times the average rate of all previous decades measured. The 10 warmest years on record all occurred in the past decade. And 2023 was the warmest year on record for North America, South America, and Africa, as well as the second warmest for Europe. As climate change continues to warm up winters and heat up summers, refrigerants will play an increasingly important role in “cooling down” people and products and helping to reduce the impact that industry and society have on “heating up” the planet. Everyone can do their part by understanding that temperature matters, then choosing refrigerant solutions that have lower GWP, support other environmental needs, and offer the right combination of performance attributes for a given climate zone.
Advanced heating, ventilation, air-conditioning, and refrigeration (HVACR) systems have always been essential to healthcare. However, the need for clean, fresh air at the right temperature and humidity within clinical settings has never been made clearer during the COVID-19 pandemic. It illustrated the importance of effective HVACR systems in healthcare due to their ability to improve air quality, patient outcomes, and infection control measures. The need for change Many current HVACR systems are outdated. Their reliance on direct on-line motor connection and mechanical methods to regulate fans, pumps, and compressors leads to inefficient energy use, generating higher costs. However, switching from manual methods to variable speed drives (VSDs) to regulate motor speeds can save as much as 25% in HVACR energy use, reducing operational costs in the process, and improving air quality control. The adoption of advanced ultra-low harmonic VSDs also improves power network reliability and efficiency. variable speed drives (VSDs) There’s the added benefit that the facility can save on the capital costs of the equipment and space VSDs also play a pivotal role in expanding the design capabilities of HVACR. One key advantage is their ability to over-speed fans within the system to cover higher loads than the system was designed for. This flexibility allows them to operate in extreme conditions and still meet the needs of the facility, without installing significantly oversized systems to cover these rare peak loads. There’s the added benefit that the facility can save on the capital costs of the equipment and space where it is installed. The challenge of harmonic distortion While newer healthcare facilities may already be equipped with HVACR systems controlled by VSDs, older facilities may require significant upgrades. Some VSDs can introduce unwanted electrical disturbances to the facility network, called harmonics, which affect the performance of electrical equipment and lead to higher energy losses. Harmonics increase line current, meaning that when fitting VSDs, power cables, and other components might need to be re-sized to be able to accommodate it. Filtering and control mechanisms Advanced ultra-low harmonic VSDs are designed to mitigate the impact of harmonics on electrical systems To address this issue, advanced ultra-low harmonic VSDs are designed to mitigate the impact of harmonics on electrical systems. Ultra-low harmonic VSDs incorporate sophisticated filtering and control mechanisms to reduce harmonic distortion, ensuring the reliability and efficiency of electrical infrastructure within healthcare facilities, including medical equipment used to treat patients. They also mitigate the need for a larger refit and higher maintenance costs, while ensuring compliance with regulatory standards governing harmonics and electrical quality. Understanding the crucial role of air quality Maintaining high air quality standards within hospitals is essential to minimize the risk of healthcare-associated infections (HAIs) and ensure the safety of both patients and medical staff. Poor air quality can lead to higher concentrations of bacteria, viruses, and fungi in the air, significantly increasing the risk of HAIs. These infections can lead to prolonged hospital stays, compromising patient safety, and further increasing healthcare costs for patients and providers. This is exactly what the COVID-19 pandemic highlighted. Regulatory standards and guidelines Only advanced ventilation systems controlled by VSDs can fully deliver what’s required Given these significant risks associated with poor air quality, healthcare facilities are subject to stringent regulatory standards and guidelines governing indoor air quality. Compliance with these standards is essential, and only advanced ventilation systems controlled by VSDs can fully deliver what’s required. Breathing easier In conclusion, advanced HVACR systems controlled by ultra-low harmonic VSDs are essential for healthcare facilities seeking to improve air quality and provide a healthier environment for patients and staff. They also enhance energy efficiency and optimize associated costs, while ensuring compliance with regulatory standards. Adopting these advanced drives offers improved medical equipment reliability, as they take care of power quality and minimize electrical disturbances in the facility's power network. Ultimately that leads to better patient outcomes and hospital operational efficiency.
By now, most of the HVACR industry is familiar with the HFC phasedown portion of the U.S. EPA American Innovation and Manufacturing (AIM) Act that was signed in 2020 and finalized in 2021. The first phasedowns started Jan. 1, 2020, with a 10% reduction in HFC refrigerant production, importation, and consumption, and was followed by an additional 30% reduction that began Jan. 1, 2024. As these regulations work to achieve a total 85% HFC phasedown from historic baseline levels by 2036, Technology transition rules will start to impact the industry as early as Jan. 1, 2025. Technology Transitions Often referred to as “sector controls,” Technology Transitions are the second of three main sections of the AIM Act. They focus on limiting the use of HFC refrigerants and supporting A2L adoption by calling for global warming potential (GWP) limits for refrigerants based on specific applications, including refrigeration, air conditioning, heat pumps, and more. three new-generation refrigerants Three new-generation refrigerants help create a clear path to making refrigerant transitions that comply with the rules Although the Technology Transitions program is rather complex (providing rules for which refrigerants or GWP limits apply for which applications and when) focusing on just three new-generation refrigerants helps create a clear path to making refrigerant transitions that comply with the rules and support more sustainable operations. While several new refrigerants have been developed recently, many of the HVACR industry’s applications and equipment can be covered by focusing on these three refrigerants: R-454A, R-454B, and R-454C. R-454A (AR4 GWP = 239) Developed to replace legacy refrigerants such as R-404A, R-454A is an HFO blend offering zero ozone depletion potential (ODP) and a GWP of 239, lower than R-404A’s GWP of 3,920. R-454A is classified as a mildly flammable, low-toxicity A2L, suitable for low- and medium-temperature commercial refrigeration applications. The AIM Act Technology Transitions set a maximum GWP of 300 for several types of systems with charge limits up to 200 lbs., such as remote condensing units for food retail walk-ins and cascade systems. These systems are ideal for R-454A, given the refrigerant’s improved performance and reduced GWP compared with R-404A. R-454B (AR4 GWP = 467) Regarding refrigerants of the future at work today, R-454B is likely the one you’ve heard the most about. Establishing itself as the predominant replacement for R-410A in new air conditioners and chillers, R-454B started being used earlier this year. R-454B will be used in most equipment manufactured after Dec. 31, 2024. Offering a GWP of 467 compared with R-410A’s GWP of 2,088 (a 78% reduction), R-454B has been selected by most air conditioning and heat pump manufacturers worldwide. R-454C (AR4 GWP = 148) R-454C, with a GWP of 148, offers compliance with AIM Act regulations and is suitable for new systems R-454C, with a GWP of 148, offers compliance with AIM Act regulations and is suitable for new systems in applications requiring a GWP of <150. Two examples are small standalone units and larger system architectures with a charge size of >200 lbs. being developed for supermarkets. For Use in New Equipment Only R-454A, R-454B, and R-454C are HFO-blend refrigerants and have slightly different R-32 and R-1234yf components percentages. All three are individually optimized for peak performance and carry an A2L mild flammability safety classification. As A2Ls, these refrigerants can only be used in new equipment designed to mitigate leaks and flammability risks and must be installed according to OEM instructions and in compliance with applicable safety standards and building codes. Easy as A, B, C In anticipation of AIM Act regulations and the continued adoption of R-454A, R-454B, and R-454C, the HVACR industry has ramped up A2L training and engineering support significantly over the past few years. So, while sorting through the regulatory changes and becoming familiar with the new refrigerant options may seem complex, focusing on these three A2Ls will hopefully make your refrigeration transition, and your business’s future growth as easy as A, B, C.

Humidity can influence employee health and productivity in the workplace. Humidity, temperature, and ventilation all work in concert to create a healthy indoor environment that supports overall occupant well-being. “Dry indoor air can cause discomfort in the form of dry skin, eyes, and throat for staff and visitors,” says Jennifer Montville, Director of Marketing at DriSteem, a manufacturer of humidification systems. Air-related health issues “There are real costs associated with health-related issues caused by dry air, including a higher occurrence of infections and increased rates of staff absenteeism?” Maintaining a comfortable work environment, including the correct humidity levels, prevents respiratory issues and reduces the spread of illnesses, ensuring a healthy working environment and boosting productivity and efficiency, says Montville. humidity levels Humidified spaces help keep facility costs down by improving thermal comfort at lower temperatures Maintaining humidity levels between 40% and 60% RH is ideal for mitigating virus transmission, she comments. Humidified spaces feel warmer and are more comfortable for employees, which in turn increases their productivity with improved concentration and less fatigue. It also helps keep facility costs down by improving thermal comfort at lower temperatures. dehumidifiers Employing dehumidifiers to keep humidity levels from rising above that 60% RH threshold is also important. Removing excess moisture from the air reduces distraction from unpleasant smells or health issues caused by mold, mildew, or fungi that thrive in moist environments. All the ways that proper humidity levels affect employee health and productivity in the workplace also contribute to increased customer satisfaction in office and retail spaces, says Montville. preventing product issues “We all prefer to spend time in places where we feel physically comfortable,” she says. “Customers in offices and retail spaces are no different. When physical comfort is not an issue, we are likely to spend more time and engage more deeply.” Well-managed humidity levels also help to prevent product issues such as shrinkage, warping, or degradation due to moisture fluctuations. Food quality is particularly impacted by humidity levels. In a retail store, this can translate to spending more time shopping in a store and a more positive opinion of the products being considered. recommended indoor relative humidity level Keeping relative humidity levels within the range ensures the health and safety of building occupants The recommended indoor relative humidity level ranges from 30% to 60% RH, according to guidelines published by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE). Keeping relative humidity levels within this range ensures the health and safety of building occupants without promoting mold growth or other indoor air quality issues. air quality goals With that said, the type of indoor space, air quality goals, and how the space is used will determine the best relative humidity levels for each facility, according to Montville. Machinery and sensitive electronic equipment are vulnerable to low or fluctuating moisture levels. Static electricity buildup and electrical malfunctions are among the potential consequences of inadequate humidity control. precise humidity control Many industrial processes depend on the consistent quality of materials, and fluctuations in relative humidity (RH) can result in less-than-ideal inputs which in turn impact the quality of final products. From preventing mold growth, spoilage, and texture deterioration in food processing to safeguarding medication stability, efficacy, and safety of pharmaceuticals, precise humidity control is critical to achieving intended results. Optimal RH levels Adequate humidity also supports the body's natural defense mechanisms, enhancing the effectiveness Maintaining appropriate humidity levels is essential for infection control. Optimal RH levels can inhibit the growth and transmission of airborne pathogens, such as viruses, bacteria, and fungi. Adequate humidity also supports the body's natural defense mechanisms, enhancing the effectiveness of respiratory tract mucous membranes in trapping and neutralizing pathogens. Conversely, dry indoor air impairs these defenses, increasing susceptibility to respiratory infections. humidity control systems Investing in commercial humidity control systems, such as those offered by DriSteem, can effectively regulate RH levels within facilities. “These systems provide flexibility and precision in catering to specific humidity needs across different areas within the facility,” says Montville. Whether integrating humidity control solutions in existing structures or implementing them in new buildings, factors such as the type of indoor space, energy source, required maintenance, and capacity determine the best technology for each building, she says.
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.
Recently, nine states pledged to accelerate the transition to clean buildings in their states, including a goal of deploying heat pumps to make up 65% of residential heating, cooling, and water heating by 2030. California, Colorado, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, and Rhode Island signed a memorandum of understanding in February outlining their collective efforts to accelerate the deployment of clean technologies such as heat pumps in new and existing homes. Benefits of heat pumps Fifteen percent of the world’s greenhouse gas emissions come from the heating and cooling of buildings and homes, and accelerating the use of heat pumps advances the goal of a cleaner, healthier environment. “The door is closing on reasons to shy away from heat pumps because the technology is here, and the incentives and support from government programs are on the rise,” says Katie Davis, VP of Engineering and Technology at Trane Residential. “There is no better time than now to make the change for a more sustainable future.” portfolio of residential heat pumps The new portfolio yields an emissions reduction of over 35% (compared to 2019), and the new 15 SEER heat pump Beginning this month, Trane Residential launches its new portfolio of residential heat pumps that achieve new levels of emissions reduction. The new portfolio yields an emissions reduction of over 35% (compared to 2019), and the new 15 SEER heat pump will meet Energy Star requirements. “We saw the change in refrigerant regulation as an opportunity to propel us forward in technology toward a better environment,” says Davis. Heat pump technology Heat pump technology has been around since the mid-1800s, and it has evolved significantly since that time. Within the last 10 years, improvements have been made in efficiency, in both the heating and cooling cycles. The use of vapor injection technology in the heating cycle has greatly improved the capacity and efficiency of heating with heat pumps. Comfort mode Comfort mode provides a level of comfort similar to that of fossil fuel-burning furnaces Trane heat pumps also can deliver very warm air at the register through Comfort mode, which provides a level of comfort similar to that of fossil fuel-burning furnaces, says Davis. Homeowners who prefer furnaces due to the temperature of the discharge air have similar capabilities with Trane heat pumps. Sustainability and efficiency Trane Technologies seeks to challenge what’s possible for a sustainable world, says Davis. “Sustainability is the foundation of how we design our products for the future of HVAC,” she says. Improvements in the efficiency of Trane Heat Pumps have a direct correlation to reduced emissions, which translates to energy savings on a homeowner’s utility bill. Trane Link systems Other factors that assist in driving the transition to the electrification of heating are utility rebates The Trane Link systems provide up to an additional 5% energy savings to the homeowner using smart technology that efficiently manages the home load environment. Other factors that assist in driving the transition to the electrification of heating are utility rebates and a program that assists homeowners in making the shift. Of course, "indirect emissions" and the greening of the grid have an impact on emissions as the industry moves toward the use of heat pumps and away from fossil fuel-burning systems. emissions reduction by design Trane is achieving industry-pioneering emissions reduction by design, and as the grid becomes greener, it will accelerate the impact the Trane portfolio will have on the industry and the environment, says Davis. “At Trane, we utilize a multi-variable approach to reducing emissions in our product portfolio,” says Davis. “While a greener grid can help to accelerate the reduction in emissions, our systems utilize smart technology, lower global warming potential refrigerants, and improved efficiency in heating design to achieve industry-pioneering emissions reduction for our systems.” alternative energy sources When designing for sustainability, several levers can be pulled to yield the best results Heat pumps play a role in encouraging more efficient energy sources. HVAC accounts for over 40% of the energy usage in a home. There is an opportunity for the development of capabilities in alternative energy sources for heating and cooling as well as improved energy management for the home. When designing for sustainability, several levers can be pulled to yield the best results. One of those levers is related to digital controls and smart systems. Trane Link Variable Speed Trane Link Variable Speed Systems provide over 700 speeds to provide a pinpoint match to a homeowner’s load demand in a home. The system provides temperature control within 0.5 degrees F, humidity control to the exact setpoint defined by the homeowner, and provides up to 5% energy savings on utility bills. By utilizing the digital technology within the control system, the heat pump manages comfort as well as efficiency to provide the best for the homeowner and the environment. For dealers, Trane provides Dealer Diagnostics that give precise information on runtime and system performance, in real time, to ensure the most optimal operating parameters for the best system performance and efficiency. heat pump heating capability Two obstacles are cost and the customer perception of heat pump heating capability Two obstacles remain in the transition journey. They are cost and the customer perception of heat pump heating capability. “As we accelerate this transition, the time is now for utilities and government programs to step up and assist homeowners in electrification of heating,” says Davis. Inflation Reduction Act (IRA) funding is a step toward this assistance, but more is needed across the industry to ensure a rapid transition to cleaner equipment. Consumer concerns In addition to cost, homeowners have not been properly educated on the advancement of heat pump technology over the last decade, and heating with heat pumps has improved significantly. “The cost to convert from furnaces to heat pumps can be prohibitive, but with government incentives, like the IRA rebates, this becomes less of an issue,” says Davis. “Other concerns from consumers are energy bills and the concern that energy costs will rise with the use of heat pumps. While it is true that electric energy bills may rise, homeowners should see a reduced cost of use of other energy sources,” says Davis. “In the end, we move closer to parity.”
Case studies
Nearly Bergamo, Italy, there is a weather station that collects meteorological data and monitors air quality. Its operation requires professional equipment that, however, works without a permanent power supply or the presence of staff. Such conditions put the equipment and other assets at risk. In fact, the station had already suffered from several intrusion attempts and needed a security system to be put in place. Challenge Protect a remote object without a permanent power supply Like many remote objects, the weather station does not have a permanent power supply and cannot afford a full-time presence of staff members on the site. After several intrusion attempts, the client needed to secure an area of 600 square meters, prevent equipment theft, and put an end to the damage made to the agricultural produce growing on the site. They looked for a professional security system that could operate outdoors without mains power and was easy to manage remotely. Solution Wireless outdoor security system with flexible power options and remote control The implemented security system consists of 11 Ajax devices, coupled with a third-party solar panel, battery, and case In response to the challenge, Von Wunster Next s.r.l. configured a solution for securing the object that has no permanent power source or staff on-site but has extensive sun exposure. The implemented security system consists of 11 Ajax devices, coupled with a third-party solar panel, battery, and case. At the core of the system, there is a Hub 2 (2G) Jeweller control panel with a low-voltage PSU 6V. The latter allows the hub to operate from an external 7 A h battery for years. The battery, in turn, is charged via the 25 W solar panel (10 A). If the external power supply fails, the hub switches to a built-in battery and continues to protect the object for up to 16 hours or even 60 hours if the Battery Power Saver feature is enabled. The client and central monitoring station of the security company instantly receive a notification about the power issue to be fixed. The company has enough time to get to the remote object for restoring power without compromising its security. A SIM card (2G) ensures connection with the network, so Von Wunster Next s.r.l. won’t miss a thing. StreetSiren DoubleDeck Other elements of the security system are wireless outdoor Ajax devices that operate with pre-installed batteries for up to 3 years. Several MotionCam Outdoor Jeweller cover the perimeter and detect movement within seconds. The device’s photo-by-alarm feature allows minimizing expensive patrol dispatches to false alarms and gives the client peace of mind. StreetSiren DoubleDeck activates the sound of up to 113 dB and bright LED indicators in response to an alarm to deter and expose intruders. Communication with the wireless devices is provided via Ajax proprietary radio protocols Jeweler and Wings at a distance of up to 2,000 m. It’s perfect for covering large areas such as that of the station. Ajax SpaceControl Jeweller key fobs Dealing with the security system is as easy as it gets for both the client and the security company The client can control security modes effortlessly. There are four end users with different rights, and they can manage the system in the Ajax app on their phones and with wireless Ajax SpaceControl Jeweller key fobs. Von Wunster Next s.r.l., which installed the system and conducts monitoring, can track the devices’ status and take care of their configuration and maintenance remotely in the majority of cases. Dealing with the security system is as easy as it gets for both the client and the security company. All the devices are either weather-resistant or reliably hidden in the case to withstand the impacts of the environment. Constant exposure to rain or sun does not affect the security system. Why Ajax Flexible power supply options. Ajax's product portfolio includes PSUs designed to connect the system to a low-voltage power supply even when no permanent power source is available. Wireless Ajax devices operate with pre-installed batteries for up to 3 years. Visual alarm verification.

A development of 16 social homes designed and built to achieve the Passivhaus standard has been constructed in Dalbeattie, Dumfries & Galloway, with the support of Baxi and its air source heat pump solutions and services. To play its part in delivering these new net-zero homes for Loreburn Housing Association, heating contractor James Frew Ltd required a solution that would provide sustainable heat to the properties; in this case, air source heat pumps. Services, training, and products The team then needed to find a strategic partner that would be able to offer the solutions and onsite support to implement the technology. Facing stringent design requirements to make the homes efficient and low carbon, James Frew Ltd partnered with Baxi to benefit from its full range of support services, training, and efficient products. energy efficiency and comfort This type of home will play a key role as local authorities and housing associations such as Loreburn Designed By Architect, Robert Potter and Partners and built by main contractor Ashleigh (Scotland) Ltd, the two and three-bedroom properties were to meet the highest standards of energy efficiency and comfort, part of Loreburn’s commitment to delivering new homes fit for the future. This type of home will play a key role as local authorities and housing associations such as Loreburn look to deliver new homes in line with the New Build Heat Standard (Scotland) or Future Homes Standard. heat pump Using the Passivhaus model, the entire home had to be designed around achieving the best energy efficiency as well as the heating source being a heat pump. This involved specifying not only the insulation and windows to meet the standard but also the correctly sized heat pump for each home. Space was also a consideration in the homes. The design needed to guarantee there was ample room for the internal and external elements of the heat pump solution, without compromising on comfort for tenants. Air source heat pumps and uSense controls The James Frew team worked closely with Baxi’s experts – Specification Manager Craig McVicar and Engineering Solutions Manager Ryan Kirkwood – to ensure the correct specification of the heat pump for the design requirements of each house. Baxi’s air source heat pumps, compatible cylinders, and uSense controls were specified to provide the heating and hot water provision for each of the 16 homes through three radiators. training, installation, and commissioning They benefitted from expert support on site, ensuring the full system was designed correctly and could be installed As part of Baxi’s heat pump service, the team of engineers had access to the company’s specialist training to allow them to become familiar with the specified solution and be confident in installing it before the project began. They also benefitted from expert support on site, ensuring the full system was designed correctly and could be installed within the space. Baxi’s Commissioning Engineers, Michael Murray, and Adam Stock were on hand to oversee the commissioning of each of the heat pumps and make certain they would operate as expected once in place at each home. design support Evan Peat, Senior Contract Manager at James Frew Ltd, said, “From tender to completion, it has been great to have the support of Baxi’s expert service throughout the process. The design support and training meant the team had peace of mind that the most suitable products would be going into the homes and that our engineers were comfortable with the installation of them." “It was also really important to have the support on-site from Craig and Ryan. Having their expertise on the ground meant we were able to overcome this challenge and still meet the Passivhaus standard.” net-zero social housing Rob Pearse, Director of Distribution Sales at Baxi UK, added, “This innovative project is a great example of how collaboration and consultation can result in amazing results for delivering net-zero social housing." "As heating solutions experts, we can work closely with social housing providers and their appointed contractors to consider the different approaches for low-carbon heating, selecting the most suitable solutions for the application." technology and intelligent design “Whether it is a new build project to Passivhaus standard like this one or decarbonizing existing developments through retrofit, we are committed to providing the complete home service to our social housing clients.” Alison Maxwell, Project Delivery Officer for Loreburn HA commented “The standard of these homes is a testament to Loreburn’s commitment to building warm and highly energy efficient homes, where technology and intelligent design come together to create a sustainable future for our tenants.” energy savings Speaking about his experience of living in one of the properties, Alan Vinnie, a Loreburn tenant added, “It’ll help to lower my energy bills which is a huge relief." "You can notice the change in the air and it’s so quiet. I think all future builds should be of this quality."
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.”

To adequately heat the 111 Murray Street residential skyscraper in New York, the owner sought an effective way to maintain the aesthetic of the mostly glass building without being obtrusive to its design. Custom convection style heaters, mounted in the building’s millwork by Faber Industrial Technologies, proved to be the game-changing resolution. “Convection heaters provide warmth and heat to a specific area or room by circulating air and heating it using a highly efficient electric element,” explained Andrew Martin, Manager of Product Management with Marley Engineered Products. He adds, “Designed for quiet, controlled comfort, they are ideal for both residential and commercial applications, including living rooms and bedrooms, offices, hallways, lobbies, conference rooms, retail stores and buildings with floor-to-ceiling windows.” Installing heaters while maintaining aesthetics 111 Murray Street is a 792-foot-tall residential skyscraper with 156 luxury condominiums Located in the Financial District and Tribeca neighborhoods in Lower Manhattan, 111 Murray Street is a 792-foot-tall residential skyscraper with 156 luxury condominiums and 2,100 square feet of retail space on the ground floor. Due to mechanical constraints exacerbated by the building’s slim design, hot water was not available in most of the upper residences, rendering hydronic heating systems impractical. Therefore, the client requested Berko ASL3 convector heaters from Marley Engineered Products to be installed for elegant, supplemental comfort for heat loss, condensation prevention and continuous warmth throughout each condo. The challenge, however, came from their preference to keep the heaters hidden for aesthetic reasons. “The varying heights and angles of the millwork in each condo limited our ability to install the heaters directly where we wanted them,” said Christopher Smith, a Heater Manufacturing Representative with Faber Industrial Technologies, adding “Therefore, we needed a custom design that enabled us to mount the heaters properly while also keeping them out of sight.” Hidden Heat for Unmatched Comfort and Elegance The solution involved fabricating and supplying custom dual inlet convector heaters, which were then mounted within the millwork of each condominium unit. Using a thermocouple array, the engineering team at Marley tested the Berko ASL3 convectors – at 125 watts per foot and 120V – inside a customer-supplied demo millwork section sent from New York City. After making some adjustments to the design, thermal couplers were utilized on both the heaters and their enclosures to ensure their surface temperatures were within Marley Engineered Products’ limits to pass a UL site inspection. Berko ASL3 convector heaters The result was an ‘invisible solution’ in which none of the controls or heaters could be seen in the residential units Next, Smith coordinated with the electrical and mechanical contractors on-site to fit the heaters into each condo’s temperature control system using power relays. The result was an ‘invisible solution’ in which none of the controls or heaters could be seen in the residential units. “Innovation and collaboration converged as we tailored a custom heating solution, seamlessly blending functionality and aesthetics,” explained Christopher Smith, adding “In fabricating this ‘invisible solution’ for the client, our dedicated team and the coordination of skilled contractors transformed these condos into spaces that harmonize comfort and elegance and exemplify the blending of form and function.” Berko ASL3 convector heaters The success of the project not only resulted in an extremely satisfied customer, but also left the contractors pleased with the uninterrupted delivery and installation of the heaters. They were further impressed when the custom heater and millwork system passed the UL site inspector’s test after just one evaluation. To acknowledge the innovative approach and exceptional achievements demonstrated by the Faber team in overcoming the challenges faced during this project, Marley Engineered Products awarded Smith the 2023 Jim Herring Memorial Silver Fox Award at its recent national sales meeting. Solving unique heating or ventilation problems “This award for excellence in solution design embodies the spirit of Herring, who was always up for a challenge and most happy when solving a unique heating or ventilation problem,” said Sean Pesce, Acting Director of Sales for Marley Engineered Products. He adds, “Chris and his team perfectly captured Jim’s talent for finding creative solutions to the most complex issues and left a lasting impression on the client.”
Shadow Industrial (SI), one of the UK’s pioneering infrared heating specialists, has been chosen to refit the heating systems at the London Boroughs of Camden and Islington’s jointly-owned Hornsey Street Refuse & Recycling Center. The decision to use SI’s cutting-edge heaters was made on the recommendation of M&E contractor, Vitalenergi London, which was appointed to update the site’s HVAC. Operational Emissions By 2030 Replacing the building’s 300 m2 existing AmbiRad fan heater system, at just over £25,000, the project will see Shadow Industrial fit 35 of its zero-emission, high-performance heaters across the entire facility. This comes in at a far lower cost, often a 50-75% saving, and increased efficiency than many other alternative electric heating systems. The project will see Shadow Industrial fit 35 of its zero-emission, high-performance heaters Predicted to reduce energy consumption by 80%, this represents a landmark moment for shortwave infrared in industrial settings. Not only that, the replacement of existing heating systems with a low-cost, more sustainable alternative perfectly aligns with both Camden and Islington Council’s Climate Action Plans which seek to achieve Net Zero operational emissions by 2030. Shadow Industrial’s Technology As Graham Hughes from Islington Council says, “When Vitalenergi first introduced us to Shadow Industrial’s technology we were very impressed, particularly by its capabilities and relatively low operational costs." "It’s going to make a massive contribution to our efforts, alongside Camden Council to reduce emissions. We’ll also be able to approach our heating strategy in a far more diverse way, keeping costs down and passing those savings onto taxpayers.” The Heat Is On The technology works by emitting focused radiant heat through precisely-configured reflectors Not only will Shadow Industrial’s heating systems shrink the center’s carbon footprint, but they will also improve energy efficiency. This is predominantly due to the way shortwave infrared works, in contrast to traditional electric and gas-powered central heating. The technology works by emitting focused radiant heat through precisely-configured reflectors. Essentially it heats the person, not the air around them, significantly reducing the amount of heat lost to the atmosphere. This comes into its own in large-span, high-ceilinged structures that experience heavy traffic constantly entering in and out, pioneering to a consistent draft. Wall-mounted or ceiling-hung, directed downwards at individuals, the energy creates a comfortable and instant warmth reminiscent of the gentle heat of the sun. In Control Plug-and-play these light heaters are easy to install and operate, compared to formal systems Plug-and-play these lightweight heaters are easy to install and operate, compared to traditional systems. It’s helping to get a practical and scalable heating network up and running within an industrial facility quickly, with minimal disruption to day-to-day operations. Even better, unlike most gas and electric systems, these heaters can be turned on and off on demand as and when personnel are working in specific areas across the site. The instantaneousness of the heat emitted means it can deliver maximum effectiveness at the click of a switch, and extinguish at the same rate. This means no part of the build is heated unnecessarily. Shadow Industrial’s Heaters As Luke Chappell, Vitalenergi’s lead design engineer (mechanical) on the project says, “Shortwave infrared’s set to be a serious market disruptor in the industrial heating market. It’s a game-changer for local authority and public sector projects, which are both subject to strict sustainability briefs and budgetary constraints." "We cannot wait to see the positive impact Shadow Industrial’s heaters will have on those working within, and managing, the Hornsey Street Refuse & Recycling Center. The Shadow Industrial team has been amazing throughout the process and we looking forward to partnering again on future projects.” Installation of Shadow Industrial’s new system was completed at the start of Q2 2024.
