"Yet, HVAC system builders often struggle to find sensors compact and lightweight enough to satisfy smaller system requirements. The DST P070 addresses this challenge by offering reliable pressure-sensing technology in a compact design," Iro Dragoumi, Segment manager for HVAC&R at Danfoss Sensing Solutions. Bi-metal pressure connection The pressure sensor features backside MEMS technology which enabled its value, size and weight to be optimal for HVAC applications. The compact bi-metal pressure connection offers the best fit in applications with small and narrow spaces, such as heat pumps, chillers, residential and transport air conditioning units and food service refrigeration. sensor’s lightweight design “The DST P070 offers the shortest solder tube length on the market, a small body sensor and a single-brazing point, all designed to make it easier for installers to work within the space constraints in heat pump installations." "And because of the sensor’s lightweight design, there’s practically no need for vibration support, which makes for a simple, effortless setup,” Katharina Löhden, Product manager for pressure sensors at Danfoss Sensing Solutions. Simplifying the installation process In addition to offering the best fit in narrow installation spaces, the bi-metal solder tube also provides several installation benefits. “When you have a pressure sensor with copper solder tubes, you need cooling protection for the sensor during the soldering process. In the DST P070, the pressure connection is made of copper and stainless steel which, in addition to being durable, can eliminate the need for cooling protection during installation. This shortens installation time and makes the entire process easier for the installer.” The bi-metal solder tube also features superior welds to the housing and precision brazing to the pipe. It also has a lower heat transfer than copper or brass, which protects system components and extends the sensor’s lifetime.  Fully compatible with low-GWP refrigerants In keeping with the company’s commitment to supporting the HVAC industry through the refrigerant transition, the Danfoss Sensing Solutions team tested the DST P070 across a wide range of refrigerants and oils to ensure its compatibility with A1, A2L, and A3 refrigerants. “We have validated that the DST P070 works with R290, the main heat pump refrigerant, and it’s compatible with the aggressive R1234ze refrigerant as well,” says Iro.  The sensor also features the company’s patented sealing technology, ensuring hermetical tightness, and has undergone a series of validation and tightness control tests to confirm it can withstand helium leakage, overpressure, thermal stress and aging, vibration and a combination of temperature and vibration exposure. Test results have been validated by an external laboratory and the DST P070 is ISO 14903 design tested and ATEX Zone 2 & HazLoc compliant.  Guaranteeing shorter lead times and supply chain integrity To meet the increasing demand for heat pumps, OEMs need a reliable supplier who can deliver system components on time. “Our customers tell us that they’re looking for global suppliers that can provide high-quality products and round-the-clock support. To accommodate this, we’ve expanded our production footprint and hence created a new, high-volume, fully automated production line in Minden, Germany. This line will enable us to offer our customers shorter lead times, so they receive orders swiftly and efficiently.” The production facility sources 70% of its materials from within the EU and offers full traceability on parts and process data. The site is also ISO 14001, ISO 9001, and IATF 16949 compliant and fully aligned with the company’s ESG commitment. “As is the case with many of our customers, Danfoss is committed to reducing our carbon footprint. In line with these goals, our facility in Minden is on track to be carbon neutral by 2030.” Putting sustainability first: from production to packaging  Sustainability has also played a significant role in the entire DST P070 production process, from manufacturing to packaging. “The sensor contains more than 50% recycled stainless steel and it has a lower total carbon footprint, thanks to its compact design and use of fewer materials,” Katharina explains. “We’ve developed a unique pulp tray packaging, which reduces our CO2 emissions by 50% and transport volume. Yet the design offers the same strength and durability to protect sensors during transport.” Combination of a simplified installation process The combination of a simplified installation process, proven quality, low-GWP refrigerant compatibility and ESG-compliance add up to a pressure sensor that equips OEMs to meet market demand, industry regulations and internal sustainability requirements. “In the DST P070, OEMs get a pressure sensor designed to work with heat pumps, chillers and other HVAC applications – one that meets the highest quality standards and that is readily available. And with our end-to-end commitment to sustainable manufacturing, we can offer a component that helps our customers work towards a carbon-neutral future,” concludes Iro.

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

As HVAC professionals know, the heating and cooling industry is undergoing a transition from refrigerants like R-410A to low global warming potential (GWP), or A2L, refrigerants such as R-454B. When preparing customers for the changes that the refrigerant shift brings, contractors can stay ahead of the learning curve by investing in staff training, purchasing necessary new tools for their HVAC technicians, and educating their residential and commercial customers about the impacts. As the industry navigates this change, below are lessons and tips to help contractors make a smooth transition to using the new refrigerants. Dealing with new refrigerants, new rules, and new challenges As new equipment has arrived, questions have come up around installation and servicing In 2025, new residential and light commercial HVAC systems must use low-GWP refrigerants. These refrigerants require new standards, new products, and enhanced safety protocols. There has been a significant learning curve for the industry, especially in the early stages of the transition. As new equipment has arrived, questions have come up around installation and servicing. Industry trade partners, such as Mitsubishi Electric Trane HVAC US (METUS), have been helpful in providing information, resources, and support. Things have been changing quickly, and while many HVAC contractors are adapting well, others are still trying to get their bearings. Part of the challenge is that manufacturers have varying requirements. Availability of A2L-compatible equipment Initially, the HVAC industry faced challenges due to the limited availability of A2L-compatible equipment and the declining supply of R-410A systems. We’ve worked to balance inventory management with maintaining customer satisfaction. In some cases, we've made two separate service visits for new system installations, first to replace the furnace and evaporator coil and then to return once the outdoor unit becomes available. Thankfully, the industry’s inventory availability has recently improved.  The refrigerant itself is still hard to come by for most contractors. Remaining vigilant and proactive, continuing to depend on trusted industry partners for timely and accurate updates is essential. Staying ahead through training and education Company pioneers should ensure their teams – not just HVAC installers but sales, service As the industry receives new information on installation, service procedures, and safety protocols, it is essential that contractor training programs are continuously evolving. Company pioneers should ensure their teams – not just HVAC installers but sales, service, and support staff – stay informed as new guidance becomes available.  Education is a core value: teams should be encouraged to attend training sessions and share what they learn with their fellow team members.  Regulations, safety procedures, and installation best practices In preparation for the transition, it’s also vital that contractors upgrade many of their tools, such as vacuum pumps, digital gauges, recovery machines, and manifolds. They should also provide their technicians with the proper training on these tools. Most importantly, contractors should take advantage of every opportunity from their trade partners, like METUS, and numerous trade affiliations, like the Air Conditioning Contractors of America (ACCA), to obtain guidance. Constantly research and share information with your team so members are well-versed on regulations, safety procedures, installation best practices, and more. Educating homeowners on potential upgrades Customers rely on contractors’ expertise to guide them through their purchase Most homeowner discussions focus on price and equipment availability rather than refrigerant types, but a few well-informed customers ask about the impact of the equipment refrigerant on their homes. Customers rely on contractors’ expertise to guide them through their purchase. Clear, helpful education builds trust, ensures understanding, and offers peace of mind for customers. It's smart and responsible to communicate about the refrigerant change to customers early, so they’re not caught off guard when their current R-410A system eventually needs replacement. They can plan and budget better with this knowledge in mind. I recommend that New York State contractors let their customers know they may be able to take advantage of the New York State Clean Heat program rebates. These rebates can be combined with federal tax credits included in the Inflation Reduction Act for switching to heat pumps and other efficient solutions. Both programs have incentivized customers to install high-performance heat pump systems. Improving performance while enhancing comfort All-climate heat pump systems using A2L refrigerants are said to be more efficient than prior generations All-climate heat pump systems using A2L refrigerants are said to be more efficient than previous generations. We’re telling our customers who switch that they can potentially lower their utility bills. The timing of these enhancements fits well with the growing demand the industry is seeing for ductless systems. Our northeastern region – which includes Amherst, New York and the surrounding Buffalo area – has started experiencing above-average temperatures, prompting many people to adopt ductless systems as a cooling solution for the first time.  I would never have anticipated this trend five years ago, and contractors in other parts of the country may be seeing the same trend. Turning disruption into a path for growth and preparedness The refrigerant transition has brought its share of challenges, but it has also sparked progress. It is essential for contractors and HVAC professionals to embrace this moment as a catalyst to strengthen their teams, invest in modern tools, and elevate customer education. By staying connected with trusted partners and industry groups, contractors don’t have to just keep pace, but they can instead position themselves for long-term success in this new era of HVAC.

The modular “block-n-lock” AHU breaks into three sections for tight-space installs, can be assembled in six different configurations to meet any need and reduce the number of SKUs a contractor needs to stock, supports both 115V and 208/230V, and fits as a direct furnace replacement.  new construction and retrofit jobs Electrification policies across the U.S. and Canada are directly shaping HVAC system design With contractor-friendly flair fittings, wireless commissioning, and rebate eligibility, EVOX is engineered for both new construction and retrofit jobs. “This system sets a new benchmark for extreme climate performance and installation flexibility,” says David Rames.  Electrification policies across the U.S. and Canada are directly shaping HVAC system design. Performance standards, building codes, and incentive structures dictate cold-climate systems. For Midea, this means designing ducted and packaged solutions that deliver 100% heating output in sub-zero temperatures, qualify for programs like ENERGY STAR Most Efficient and CEE Advanced Tier, and integrate with demand response platforms. Advanced inverter-driven all-weather systems “We have also partnered with agencies on programs such as New York’s Clean Heat for All Challenge, deploying retrofit-ready Packaged Window Heat Pumps at scale,” states David Rames, adding “Policy isn’t just a driver; it’s a roadmap for innovation and deployment.” Looking ahead, Midea is investing in advanced inverter-driven all-weather systems, modular AHUs, and compact packaged solutions that simplify retrofits. The pipeline includes next-generation EVOX models with higher coefficients of performance (COPs) at sub-zero temperatures, grid-responsive controls, wireless communication, and compatibility with smart thermostats.  Midea investing in advanced inverter-driven all-weather systems. Contractor training and installation quality The company is also expanding into domestic hot water with a Heat Pump Water Heater (HPWH), which delivers up to 400% efficiency and qualifies for most U.S. and Canadian rebates. Supporting the innovations are hands-on contractor training and ongoing collaboration with utilities and trade schools.  Midea is addressing this with modular AHUs, guided commissioning tools, and a nationwide training network “Our goal is clear: To equip the market with scalable, installation-friendly solutions for every climate,” says David Rames. Contractor training and installation quality remain the biggest challenges. Improper sizing, restrictive airflow and misassembled equipment can still undermine performance. Midea is addressing this with modular AHUs, guided commissioning tools, and a nationwide training network. Modern heat pumps Cost is another barrier, but broad rebate eligibility helps homeowners offset upfront expenses. Also, consumer awareness is lagging as many still do not understand that modern heat pumps provide reliable heating in extreme cold in addition to reliable cooling. “Overcoming these hurdles requires contractor education, consumer outreach, and continued investment in easy-to-install, high-performance equipment that reduces callbacks and increases homeowner confidence,” says David Rames. Midea’s forthcoming EVOX All Climate In fact, the misconception persists that heat pumps do not work in cold climates despite modern systems like Midea’s forthcoming EVOX All Climate that deliver up to 100% heating output at down to −31°F and continuous operation down to −40°F. The DOE-tested systems achieved a COP of 1.92 at down to −15°F, outperforming cold-climate benchmarks.  However, a Midea-commissioned survey showed that nearly half of homeowners did not know heat pumps can both heat and cool, and only 4% knew that today’s systems can maintain capacity in sub-zero temperatures. “The truth is, inverter-driven, EVI-equipped heat pumps provide year-round comfort more efficiently than conventional systems, and education is critical to correcting outdated perceptions,” concludes David Rames.

With the acquisition of Johnson Controls’ residential and commercial HVAC business, Bosch’s Home Comfort Group has vastly expanded its global footprint. The acquisition, which was finalized on July 31, expands Bosch’s North American presence to complement its already dominant positions in the rest of the world. Champion in the HVAC and water space The newly combined businesses will include 26 research and development facilities globally and 33 factories worldwide.  Previously, about 80% of Bosch’s Home Comfort Business was in the Europe, Middle East, and Africa region “Bosch has really expressed their desire to be a global champion in the HVAC and water space, so that’s really the premise behind the global acquisition,” says David Budzinski, President, Bosch Home Comfort Group, Americas.  Previously, around 80% of Bosch’s Home Comfort Business was in the Europe, Middle East, and Africa region. The acquisition adds particular strength in the North America and Asia-Pacific regions, resulting is a trinity of big regional businesses combined under the Bosch global umbrella. Tremendous potential for growth in US There will be no immediate changes noticeable in how the businesses operate, according to David Budzinski. Over the next several years, one can expect more integration where it makes sense, yielding eventual cost benefits.  “We are always looking at ways to decrease the cost of our products for contractors and consumers alike,” said Budzinski, adding “We want to leverage the strengths from both sides.” The acquisition provides tremendous potential for growth in the United States. “Bosch is very serious about growing in the Americas, and so it’s an incredibly important market, arguably one of the most important for the company,” adds David Budzinski. Residential and light commercial HVAC businesses Bosch will continue to use the brand names Hitachi and York under licensing agreements The acquisition includes the Johnson Controls-Hitachi Air Conditioning joint venture in addition to JCI’s other residential and light commercial HVAC businesses. Bosch will continue to use the brand names Hitachi and York under licensing agreements, in addition to their Bosch branding. The businesses are merging with Bosch Home Comfort Group, part of the global company’s Energy and Buildings business, one of four main pillars of the vast company.  JCI residential and light commercial businesses The combination of the legacy JCI residential and light commercial businesses with Bosch’s existing business in North America positions Bosch as one of the “Big Six” HVAC manufacturers in North America. Bosch was already a North American pioneer in heat pumps and water technologies. An advantage of the combined companies is a larger product portfolio, included ducted and ductless technologies provided by the JCI-Hitachi unit. It’s a whole new side of the portfolio, joining Bosch’s strength in air-to-air and air-to-water heat pump technologies. Bosch was already a North American pioneer in heat pumps and water technologies. Economics of scale and synergy A regional approach allows the company to cater the strategy to each individual region “Being a global HVAC company allows us to continue and expand our existing economics of scale and synergy,” says David Budzinski.  A regional approach allows the company to cater the strategy to each individual region, whether North America, China, Japan, or Europe. The goal is, in effect, to do “whatever it takes for us to win,” said David Budzinski.  “It takes a slightly different strategy to win in the U.S. versus what it takes to win in Europe versus Japan or China,” says David Budzinski, adding “Bosch has been a global player for over 100 years, and we have a very strong strategy.” Switch to lower-GWP refrigerants Investment in research and development (R&D) is critical in the U.S., given the ever-shifting business and regulatory environment. For the last six years, the focus in the U.S. has been responding to regulatory changes. With that transition in the rearview, including the switch to lower-GWP refrigerants, it is time to focus more on end users and contractors, says Budzinski.  “We are focused on portfolio enhancements and helping our end users and contractors install the product faster and easier in order to essentially decrease the cost of the product, including installation time,” states David Budzinski, adding “We are growing our portfolio to help consumers be able to afford to replace their HVAC.” Broad Bosch portfolio Uncertainties in the replacement cycle and housing market are among the unknowns Uncertainties in the replacement cycle and housing market are among the unknowns as one looks ahead to the future, but Bosch is responding. “We’re doing our part to work with contractors, our dealers, and distributors to make sure we continue to make new installations achievable and affordable with or without incentives for homeowners,” adds David Budzinski.  The broad Bosch portfolio, including the products that are part of the acquisition, ensures the company can serve customers regardless of what happens on the political or regulatory front.  Benefits of the new ownership  “We are going to produce, engineer and develop products that our customers want, and that’s super critical as a business and helps us to be more agile,” said Budzinski. Overall, Budzinski expects Bosch’s business to grow faster than the overall market. “The acquisition helps us leverage economics of scale, which was one of the main drivers of the transaction,” adds David Budzinski.  Among the benefits of the new ownership is operation by a private company (Bosch) as compared to a publicly traded company (JCI). Being a private company enables a longer-term emphasis on growth and investment, rather than focusing on short-term concerns such as exceeding quarterly earnings estimates, for example. Private companies are well-equipped to weather market volatility. Impact of tariffs for Bosch’s supply chain partners Given the ongoing uncertainties about tariffs, Bosch is well-positioned with manufacturing and R&D facilities in the U.S., including large facilities in Oklahoma and Kansas. There will be some expected impact of tariffs for Bosch’s supply chain partners; some components are made outside the United States. Bosch’s U.S. facilities support the currently popular notion of “Investing in the United States,” according to Budzinski. “We have created a global climate comfort champion,” said David Budzinski, adding “We are a large, global-scale company that focuses on creating the best products and technology for our customers.” Bosch’s forecast Bosch’s forecast is that sales of air conditioning units worldwide are hoped to rise to more than 200 million per year According to Bosch analyses, the global market for heating, ventilation, and air conditioning systems amounted to more than $160 billion USD (150 billion euros) in 2024. Air conditioning systems alone accounted for two-thirds of this. Demand will continue to increase significantly in the coming years.  According to Bosch’s forecast, sales of air conditioning units worldwide are expected to increase to more than 200 million units per year by 2030, almost a fifth more than in 2024. Ambitious growth targets “With the largest acquisition in our company history, we are accelerating our growth, expanding our global footprint, and balancing our business by strengthening our energy and building technology – this makes Bosch more powerful and robust, in line with our corporate strategy,” says Stefan Hartung, Chairman of the Bosch board of management.  “We have ambitious growth targets in all regions of the world. We are consistently focusing our new organization on this,” says Jan Brockmann, Executive Management President of Home Comfort, adding “By strengthening regional responsibility, we can meet customer needs even better.” Strategic investments in growth areas “Bosch wants to be one of the pioneering companies in each of its industries by 2030 and is expanding its business with strategic investments in growth areas, among other things. Acquisitions are also part of the strategy,” says Christian Fischer, Deputy Chairman of the Board of Management and responsible for strategic growth initiatives and portfolio management. Christian Fischer adds, “The current acquisition perfectly complements our portfolio. We can now offer our customers the entire range of HVAC technologies – from a single source and worldwide.”

Homes should provide a healthy sanctuary for their occupants, and HVAC can achieve that goal by providing better air quality and a constant flow of fresh and filtered air. However, better air quality comes at a cost. “We have a lot of solutions to improve air quality, but we have to be able to communicate the value of indoor air quality (IAQ) to get people to pay the added cost,” says Panasonic’s IAQ expert, Ken Nelson. “Anything that raises the price of a house diminishes the sale.” Value of indoor air quality The value of indoor air quality is not in dispute but getting that message across is a challenge For example, a system that ensures indoor air quality would increase the price of a new house, but the builder or realtor would likely be unable to articulate the value of the system to a new homebuyer.  A system to ensure better air quality would be invisible to a potential homeowner, and the value would not be obvious unless it is carefully communicated. The value of indoor air quality is not in dispute but getting that message across is a challenge. Solution to improve air quality “The challenge is that any solution to improve air quality has to be sold, and it’s a function of understanding the balance of cost, price and value,” says Nelson. “It’s a sellable concept to the buyer, but you have to be able to explain it, bring it up, put it out there. Whose job is it to make sure everybody in the purchase chain has an understanding of air quality?” As group sales manager of ventilation at Panasonic Eco Systems, North America, Nelson has a stake in promoting a higher level of communication about the value of indoor air quality. He also sells a solution to meet the challenge, a system that can also help homebuilders stand out in the real estate market. Panasonic OASYS HVAC and indoor air system Panasonic OASYS HVAC and indoor air plan ensures a even indoor temperature throughout the home Designed for highly airtight and insulated houses, the Panasonic OASYS HVAC and indoor air system ensures consistent indoor temperature throughout the home.  The system combines a ductless mini-split air conditioner with a continuous heat exchanger and an energy recovery ventilator (ERV), which exchanges stale indoor air with fresh outdoor air while also transferring heat and moisture between the two air streams. The ERV reduces the load on the air conditioner and suppresses PM2.5 (fine inhalable particles). The OASYS system takes in fresh outdoor air, filters it, tempers it to the homeowner’s temperature setting, and then circulates it constantly throughout the house for approximately four air changes per hour while continuously monitoring the air for comfort. DC motor-driven ventilation fans Pushing air through six-inch ducts throughout the house are small, DC motor-driven ventilation fans, which are quieter and use less energy. Constant air flow controls humidity throughout the house with perpetual air movement and ventilation to help prevent excess moisture and mold. Smaller fans drive air throughout the house, and perhaps 25 supply fans might be used in a typical house, and each fan has its own 6-in. duct. Supply air is filtered to a MERV 13 standard in case there are PM2.5 particulates from surrounding sources. OASYS system features In contrast, a conventional home HVAC system might use a large, central fan that pushes air through a larger trunk line, typically located in the attic, and then through smaller ducts to each room. In a conventional system, fans operate intermittently based on heating or cooling cycles, while the OASYS system features continuous air flow 24/7. OASYS, which has been deployed extensively in Japan and throughout the world, recently entered the U.S. market. Worldwide, 10,000 to 15,000 houses per year are built using the system. Conventional home HVAC system might use a large, central fan that pushes air via a larger trunk line. OASYS system concept The 2,700-square-foot home is being used to exhibit the OASYS system concept and to offer an experience In January 2025, Panasonic opened the OASYS concept home in Houston, Texas. The 2,700-square-foot home is being used to exhibit the OASYS system concept and to offer firsthand experience to business-to-business customers such as builders. Panasonic seeks to expand its central air conditioning business in the U.S., leveraging a competitive strength in ventilation fans, and to promote initiatives to optimize home energy management in the future, such as linking the system to other energy-saving devices. OASYS installations The OASYS design team works with builder and design partners and energy-raters to help them understand how the system works and what is required. For example, a tight-envelope, high-performance house is needed. Globally, many OASYS installations involve residences in the 1,200-square-foot range, which highlights opportunities to use the technology in multi-tenant housing applications in the U.S. The strategy is to work with “OASYS-certified” builders to ensure the concept is deployed effectively. Negative health effects OASYS is not an easy retrofit because it requires additional pathways through and between the floors OASYS is not an easy retrofit because it requires additional pathways through and between the floors, and because existing housing may not be sufficiently airtight. During the height of the COVID pandemic, IAQ briefly became top-of-mind, but awareness has waned since then, and many lessons learned from the pandemic have been pushed aside. Today, there is less concern about how an aerosolized microbe might get into the lungs with negative health effects, for example. Greater awareness is needed, says Nelson. Superior indoor air quality Failing to provide superior indoor air quality has consequences, but they may not be obvious or immediate, he says. Rather, they will become obvious over time. For example, a single burning candle might emit a PM2.5 particulate, which would pass through a resident’s bloodstream without obvious effect. However, the consequences of 10 years of burning candles, or the equivalent of other contaminants, would likely create adverse health effects. Better ventilation is key. “Instead of heating and cooling driving the ventilation, we have ventilation driving the heating and cooling,” says Nelson.

Mitsubishi Electric Trane HVAC US LLC (METUS), a major supplier of all-electric, all-climate Ductless and Ducted Mini-split and Variable Refrigerant Flow (VRF) heat pump and air-conditioning systems, highlights a customer success story showcasing how Mitsubishi Electric VRF technology supports the Westin Atlanta Gwinnett’s commitment to guest comfort. Opened in March 2024, the Westin Atlanta Gwinnett is Gwinnett County’s only full-service hotel and a standout property from Concord Hospitality Enterprises. With 348 guest rooms and suites, seven guest room floors, event space, a restaurant, a fitness studio, and a rooftop bar, the property needed an HVAC system that delivered high-quality performance for every area. Mitsubishi Electric’s VRF technology made that possible in guest rooms, while Trane, a partner of METUS, provided rooftop units to serve common areas like ballrooms, meeting rooms, hallways, and the hotel lobby. Personalized climate control Mitsubishi Electric VRF systems offer personalized climate control in each room. Guests can easily adjust their thermostats, and in larger suites, the system design was tailored to promote even comfort regardless of room size. Zoning for every room is designed to prevent wasted energy on unoccupied spaces, a crucial advantage in a hotel with 348 rooms. “From day one, Mitsubishi Electric’s VRF heat pump system has delivered energy performance beyond expectations,” said Carl Hren, Executive Vice President of Development at Concord Hospitality Enterprises, which developed the property. “We’re seeing lower electrical bills than we would have expected for a hotel of this size.” Additionally, unlike bulky vertical terminal air conditioner (VTAC) closets that take up valuable real estate and sometimes are positioned to blow air directly onto the bed, the Westin’s VRF units are concealed in ceiling soffits near room entries, allowing for better airflow control and a cleaner layout. Excellence in guest experience “The Westin Atlanta Gwinnett proves that true hospitality isn’t just seen, it’s felt,” said David Archer, Vice President of Commercial Business at METUS. “With our all-climate VRF systems delivering whisper-quiet, personalized comfort behind the scenes, guests can fully relax and recharge. This project reflects how our technology creates a luxury hospitality environment while meeting modern standards for energy performance.” This marks the fifth project Concord Hospitality Enterprises has completed with METUS, and Concord Hospitality has already started specifying Mitsubishi Electric VRF systems for future projects based on the system’s performance at the Westin Atlanta Gwinnett. The property’s success was further recognized when the Westin Atlanta Gwinnett received the 2024 Marriott Full Service Opening Hotel of the Year Award, an honor given to top-performing new properties that demonstrate excellence in guest experience, operational execution and brand standards.

The Holiday Inn Express San Diego South – Chula Vista is a contemporary 3-star hotel with 88 spacious guest rooms across four floors. The property offers easy access to downtown San Diego, the Gaslamp Quarter, San Diego Zoo, beaches, and the Convention Center – making it a popular choice for both business and leisure travelers. Amenities include a year-round outdoor pool and hot tub, fitness center, business facilities, and free parking. Competing in one of the nation’s most demanding hospitality markets, the hotel is constantly looking for ways to improve efficiency and service. Smart thermostats General Manager Victor M. Carrera recently introduced Anacove AI-powered Smart Thermostats To meet these challenges, General Manager Victor M. Carrera recently introduced Anacove AI-powered Smart Thermostats and Asset Tracking devices, along with an initial pilot of the company’s Staff Alert Smart Nametag solution. All are controlled through the easy-to-use Anacove Smart Dashboard, which provides real-time insights without adding complexity for staff, generating monthly flash reports summarizing energy savings and asset activity. The deployment quickly delivered measurable results. Energy savings “We’ve already noted measurable energy savings and project results in line with our sister hotels,” said Carrera. “I’ve also been very impressed by the Anacove Smart Thermostat’s ability to pre-cool rooms before arrival, a great advantage that improves guest satisfaction while also reducing HVAC strain. The system also flags malfunctioning AC units early, allowing us to deploy our maintenance teams before problems escalate – helping to reduce repair costs and mitigate guest complaints.” Energy efficiency There has been a clear drop in monthly electric bills and lower kilowatt-hour usage Energy efficiency was the most immediate benefit. There has been a clear drop in monthly electric bills and lower kilowatt-hour usage, in line with other Holiday Inn Express properties. A previous trial by Holiday Inn parent company IHG Hotels & Resorts showed Anacove Smart Thermostats significantly reducing HVAC energy use. With savings of 30-40% on average and a payback period of 12-14 months. San Diego is reporting similar results, according to Carrera. Anacove Asset Tracking Devices Operational gains go beyond HVAC. By tagging luggage carts and cribs with Anacove Asset Tracking Devices, the hotel has virtually eliminated losses and has slashed retrieval times. Staff can now instantly locate equipment for reassignment or billing via the dashboard, eliminating one of the most common frustrations in hotel operations. This accountability saves time and ensures items are always available for guests. Remote AC control “With remote AC control, front desk teams can fix room comfort issues instantly without sending maintenance, remotely via the simple dashboard from the front desk – eliminating the need to physically go to the room,” explained Carrera. “That frees them up for other tasks and means guests benefit from quicker, more efficient service. Being able to easily locate hotel collateral is a boon too. All of these time savings are already feeding into better guest satisfaction and will likely reduce our payroll costs in the long run.” Staff safety Staff safety has also been strengthened through location-enabled name tags, currently in use by a third of the 30-strong team. Initially met with caution, the devices have quickly proven their worth. They allow for rapid response in emergencies – especially in areas not covered by cameras – and provide hotel management with data on room servicing times, which helps improve training and workflows. Support and affordability Carrera praised Anacove’s attentive support and affordability compared to larger competitors Reflecting on the rollout, Carrera praised Anacove’s attentive support and affordability compared to larger competitors. Keen to work closely with Anacove on any potential improvements, he suggested dashboard enhancements such as a map-based view to visualize asset and staff locations, and also expressed interest in predictive diagnostics – such as identifying AC compressor issues before failure – that could further reduce costs. User-friendly dashboard “I’m delighted with both Anacove’s solutions, backed up by the user-friendly dashboard, and the company’s close involvement with the requirements of our business,” Carrera said. “We’ve seen electric bills go down, we can pre-cool rooms for our guests, and we’re identifying non-working AC units faster.” He added: “The identifiers for luggage carts and cribs have minimized losses and improved accountability, and the name tags with location devices enhance staff safety and allow us to monitor performance. Anacove’s support has been excellent, and their solutions are cost-effective compared to others in the market.” AI-driven Anacove’s solutions By adopting AI-driven Anacove’s solutions, the Holiday Inn Express San Diego South – Chula Vista has established itself as a sustainable, efficient, and forward-thinking hospitality property in a highly competitive market, where guest expectations are high and operational margins are tight. With technology that is both powerful and simple to use, the hotel is reducing energy and payroll costs, strengthening safety, and enhancing the guest experience – illustrating how smart systems can deliver a genuinely competitive edge in modern hospitality.

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

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

When construction began on 499 Summit Avenue, a new high-rise residential development in Jersey City, the design team at Barone Engineering already had a trusted HVAC partner in mind, QMark, specified for its performance, flexibility, and reliability in demanding building environments. But winning the bid wouldn’t be easy. As multiple distributors began quoting comparable products from both QMark and various competitors, cost quickly became a sticking point. Securing the project Enter Christopher Smith of Faber Industrial Technologies, a manufacturer’s rep agency located in Clifton, NJ who has built a reputation on more than just delivering quotes, they solve problems. Working closely with Turtle & Hughes, a regional electrical distributor, Smith helped secure the project and deliver a heating system design that honored the engineer’s spec, met the contractor’s budget, and demonstrated the kind of responsive ingenuity that defines Marley Engineered Products’ Silver Fox Award.  “From the start, this project was highly competitive,” said Smith. “But our relationship with Barone Engineering and our ability to offer intelligent value-engineering through QMark products gave us a strategic edge.” Smart Substitutions, Seamless Collaboration Faber was able to provide equivalent wattage and voltage in a more cost-effective package The original spec called for a mix of ceiling and wall mounted electric heaters across multiple zones of the high-rise, including tenant corridors, back-of-house spaces, and mechanical areas. Faber identified several opportunities for value engineering, particularly in product swaps that preserved performance without compromising the design intent. For example, by switching from the initially specified CWH3000 units to CZ2048T and CWH1207DSF models, both from QMark, Faber was able to provide equivalent wattage and voltage in a more cost-effective package. Minor adjustments to thermostat kits The team also recommended minor adjustments to thermostat kits and mounting configurations The team also recommended minor adjustments to thermostat kits and mounting configurations to streamline installation and minimize labor costs. “With a little extra help from Marley’s team, we were able to fine-tune the order to meet the contractor’s budget,” Smith said. “In the end, our distributor and the contractor both felt like they won. They maintained spec, came in under budget, and avoided unnecessary redesign work.” Performance-Driven Product Selection The final equipment package included more than thirty product lines tailored to meet the diverse heating needs The final equipment package included more than thirty product lines tailored to meet the diverse heating needs across the 499 Summit development. Among the key selections were QMark’s QCH1202F ceiling heaters, compact, quiet units ideal for tenant corridors and common areas, and multiple 480V MUH series unit heaters (MUH0541, MUH0341, MUH074), which offered rugged, high-capacity performance for mechanical rooms, stairwells, and larger open spaces. For freeze protection in concealed or inaccessible ceiling areas, Faber recommended CHPR25 plenum-rated units, which met local code requirements while maintaining clean architectural lines. Corrosion-resistant QWD washdown heater The package was rounded out with a full suite of thermostats, mounting brackets, and field-install kits A corrosion-resistant QWD washdown heater with 5kW output and 24V controls was specified for the building’s high-moisture environments, and heavy-duty CUH cabinet unit heaters were deployed in utility rooms, offering up to 10kW of ducted airflow capacity. The package was rounded out with a full suite of thermostats, mounting brackets, and field-install kits, ensuring a complete, coordinated installation. Every piece of equipment was delivered on time and configured to spec, backed by Marley Engineered Products’ reputation for reliable, durable solutions. A Win for All Parties The scope of the heating installation at 499 Summit, spanning more than 90 unique equipment line items, represents a major achievement in specification support and cross-channel coordination. The project is now slated for completion in 2026 and is part of a growing portfolio of high-rise residential developments reshaping Jersey City’s skyline. “This project helped drive Turtle’s monumental growth in 2024,” said Smith. “It also reinforced Faber’s standing as a trusted partner to engineers, distributors, and contractors alike.” 2025 Jim Herring Memorial Silver Fox Award Christopher Smith has been honored with the 2025 Jim Herring Memorial Silver Fox Award For his role in the successful bid, creative problem-solving, and commitment to specification integrity, Christopher Smith has been honored with the 2025 Jim Herring Memorial Silver Fox Award, presented annually by Marley Engineered Products. “This award embodies the spirit of Jim Herring, who had a talent for finding creative solutions to specialized HVAC challenges,” said Sean Pesce, Sr. National Sales Manager for Marley Engineered Products. “Christopher and the Faber team exemplified that spirit by turning a competitive bid into a collaborative success. We’re proud to recognize their work.”

Utility incentives are a useful tool to drive sales of high-efficiency HVAC equipment, like heat pumps, by reducing upfront costs (rebates) for consumers. This increases demand, stimulates technological innovation by manufacturers, and provides higher-value projects for contractors, ultimately accelerating the shift to energy-efficient systems. To elaborate on this topic, we asked our Expert Panel Roundtable: How can utility incentives benefit the HVAC market?
