It is now more common to read about cases of Legionnaires’ disease in the media than ever before, with outbreaks regularly being reported in cities around the world, all the time. Many of these cases are attributed to contamination of domestic systems, showers and spas, but some are the result of operating cooling towers. While this problem is not new, with the first reported case in Philadelphia, in 1976, the United Kingdom (UK) has been at the forefront in leading the battle with Legionn...
The concept of district heating refers to a group of customers, or even a whole city, which shares a system providing ambient heat, often using steam or water heated by sources that emit less carbon dioxide. A network of insulated pipes, constructed underground in a community, transports the heat among customers, and various meters and billing systems keep up with how much heat is provided. District heating District heating is seen as an increasingly important option, as municipalities seek to...

A number of standard unit coolers from Friga-Bohn, which supplies a wide range of refrigeration solutions to the food industry, are now fully compatible with A2L refrigerants. The unit coolers support use with both new A2L refrigerants such as R1234yf, R454C and R455C, as well as existing HFC refrigerant solutions. As a result, a single unit can provide for present and future requirements, reducing inventory for wholesalers and easing selection choices for installers. The market for unit coolers is changing. The F-Gas regulation means that a ban is now in place for new installations using refrigerants with a GWP (Global Warming Potential) of more than 2500. Diminishing production quotas Furthermore, other refrigerants are having their availability limited by diminishing production quotas, which is consequently affecting prices. Refrigerant producers have to fall within a regulation-defined limit of Teq CO2 (carbon dioxide equivalent tonnes) per year. So opting to produce a refrigerant with a high GWP means less product availability, leading to a higher price. CO2 is, of course, an option, but alternatives such as A2L refrigerants are very attractive CO2 has become the preferred refrigerant in high-capacity refrigeration installations thanks to its low GWP and good thermo-physic properties. However, for small/medium-capacity systems, the choice is not so obvious. CO2 is of course an option, but alternatives such as A2L refrigerants are very attractive as their constituent technology is similar to HFCs while offering a far lower GWP. Existing refrigerant solutions To ensure simplicity of choice for installers, Friga-Bohn can now confirm that a number of its unit coolers offer compatibility with new A2L refrigerants, as well as existing refrigerant solutions. This approach differs from other market systems, which are only suitable for one or the other. Wholesalers, therefore, benefit as they only need to stock a single type of unit cooler – one capable of meeting the requirements of both applications. The A2L-compatible coolers now available from Friga-Bohn include MR and MH series ceiling units, NTA dual-discharge units, and 3C-A cubic units. Typical applications include cold rooms in cafes, hotels, bars, restaurants, local shops, minimarkets, and supermarkets, with options available to suit both positive and negative temperature conditions. Comprehensive risk assessment Friga-Bohn can offer several newly developed tools to help simplify this process for installers Despite their low GWP (R1234yf, R454C, and R455C have a GWP of less than 150), A2L refrigerants carry a ‘slightly flammable’ security classification. For this reason, all Friga-Bohn unit coolers using A2L refrigerants have been subject to a comprehensive risk assessment, with INERIS, the French National Institute for Industrial Environment and Risks, providing full approval and validation. A risk analysis is also necessary for each installation to ensure safety for users and the general public; a process that should take into account the entire refrigeration system as well as its environment over the product life cycle. Here, Friga-Bohn can offer several newly developed tools to help simplify this process for installers. The availability of these tools ensures that the ‘slightly flammable’ classification of A2L refrigerants should not be an obstacle in reducing the industry’s carbon footprint. Lower GWP refrigerants In summary, A2L refrigerants are a good solution when transitioning to lower GWP refrigerants. They provide the opportunity to reduce environmental impact and comply with the F-Gas regulation for small/medium capacity installations. However, changing to A2L does require some technical knowledge. Here, Friga-Bohn is ahead of market competitors – the company is fully prepared and ready to help wholesalers and installers with any assistance they may require in helping the food sector achieve a safe and effective switch to a future based on low-GWP refrigerants. Friga-Bohn can also help wholesalers to educate installers about this important industry shift.

Baltimore Aircoil Company (BAC) highlights the TriArmor Corrosion Protection System which provides the best corrosion and leak protection for the cold water basin at the best value. For over 20 years, thousands of cooling towers, fluid coolers, and condensers with the TriArmor System have withstood the harshest environments, proving its durability and reliability. This patented system designed specifically for evaporative cooling equipment for HVAC, Industrial, and Refrigeration applications is now backed by a pioneering 10-year warranty. The TriArmor System offers three layers of protection, starting with G-235 Galvanized Steel, the heaviest commercially available galvanized steel. Universally recognized for its strength and durability, it offers excellent service life under normal operating conditions, with proper maintenance and water treatment. Thermosetting Hybrid Polymer Polyurethane Barrier is a factory-applied, corrosion-resistant, impermeable coating that ensures a seamless basin The second layer is a Thermosetting Hybrid Polymer baked onto the galvanized steel to create a durable barrier. This polymerized coating has been tested to withstand 6,000 hours in a 5% salt spray without blistering, chipping, or losing adhesion. The third layer, a Polyurethane Barrier, is a factory-applied, corrosion-resistant, impermeable coating that ensures a seamless basin. To help ensure leak-free longevity, microscopic chains of rubber-like resin molecules permanently bond tightly with one another and the thermosetting hybrid polymer. These three layers of protection form a bond for the ultimate in corrosion resistance and leak protection. TriArmor Corrosion Protection In addition to real-world testing over the past two decades, the TriArmor Corrosion Protection System has also been subjected to a series of rigorous corrosion tests including an acid test (pH=4), an alkaline test (pH=11), a chloride level test, and a 5% salt spray test. Basins also endured heavy impact testing. Remarkably, there were no penetrations left in basins protected by the TriArmor System. These tests all conclusively demonstrate that the TriArmor System is superior to stainless steel. Protection of the cold water basin is the easiest way to extend the life of evaporative cooling equipment. As long as the basin is in good condition, nearly every other part of the equipment can be repaired or replaced.

At the moment, it seems as though a day rarely goes by without low-carbon heating hitting the headlines. Whether it is reports of ‘revamping’ the Clean Heat Grant, to include a ‘boiler scrappage’ scheme, which may offer home owners up to £7000 to make the switch to a low-carbon alternative, to speculation that the Prime Minister is under pressure to push back the 2035 ban on gas boilers, the debate on how and when the low-carbon heating revolution will happen is ongoing. BEIS Hydrogen Strategy We have also seen the recently published, Hydrogen Strategy from the Department for Business, Energy and Industrial Strategy (BEIS) that cements its plans to develop technologies that allow hydrogen-powered heating in people’s homes. In addition to this, the Future Homes Task Force, including some of the United Kingdom’s largest property developers, regulators, suppliers and environmental groups, have agreed to the sector-wide Future Homes Delivery Plan, to build homes that are ‘zero-carbon ready’ and sustainable by 2025. Alternative energy, key to hitting net zero targets by 2050 What is also clear is that tackling the decarbonization of heat is not a one-technology solution According to the Climate Change Committee, in a report published in December 2020, the UK’s homes are responsible for around 15 percent of emissions. As a result, the need to install alternatives to traditional fossil fuel heating systems will be crucial, to hitting our net zero targets, by 2050. This will be the key challenge that the delayed Heat and Buildings Strategy, now due in the autumn season, will need to address. Therefore, what is also clear is that tackling the decarbonization of heat is not a one-technology solution. Target to install air source heat pumps in UK homes So far, much of the focus has been on heat pumps, as the UK Government has set an ambitious target of installing 600,000 air source heat pumps (ASHPs) in UK homes each year, by 2028. However, there are a number of challenges to achieve this goal, as house builders will need convincing to install heat pumps in new builds, and home owners and landlords will need convincing to retrofit older properties. Cost, a key issue in air source heat pumps installation Cost will also be a key issue, even with a government grant and ASHPs can be complex to install. They can also emit noise that breaches legal limits, if placed too close to a neighboring property. In addition, they won’t be suitable for all properties, as the needs of a 4-bedroom new build home are very different to a 1970s apartment, a Victorian-era terrace, a social housing property or an off-grid home. Computer-controlled infrared heating (CCIR) One of the alternatives is computer-controlled infrared heating, which addresses many of the issues faced by ASHPs Taking all of these challenges into account, BEIS has said that it is ‘uncertain’ what the ‘optimal solution’ is, when it comes to low-carbon heating. Certainly, there is not a ‘one-size-fits-all’ solution for heating the UK’s homes, which is why it is vital that house builders, landlords, contractors, installers and developers explore the full range of low-carbon heating technologies that are available today. There are alternatives that can provide benefits that are much more likely to appeal to a wider range of end-user audiences. One of the alternatives is computer-controlled infrared heating (CCIR), which addresses many of the issues faced by ASHPs. High-performance heating Firstly, infrared is an intrinsically more effective source of heat than conventional convection heating, because it heats the material within a room, rather than the air, which can escape from doors and windows. CCIR systems also outperform many other low-carbon technologies, because the software within each panel constantly monitors each individual room and learns about the energy storage characteristics within it, adjusting its routine to maintain the ambient temperature within the room, maximizing its performance and using fewer units of energy, in comparison to a traditional heating system. KERS water heating system This keeps energy bills low, and meets increasing sustainability standards. Figures show that, out of 29 million homes in the United Kingdom, 19 million have an EPC lower than C. Together with Ambion Heating’s KERS water heating system, inefficient properties can be brought up to a minimum EPC C. CCIR also costs less to install than many other low-carbon heating alternatives CCIR also costs less to install than many other low-carbon heating alternatives. In a typical three-bedroom house, for example, the estimated cost of installing a CCIR system is around £6,000, compared to nearly £10,500 for an ASHP. They are also easy to install, whether they’re being retrofitted into an existing building or installed within a new build, because they can simply be wired into the mains, by a qualified electrician. Enhanced comfort and reduced emissions The heat CCIR provides feels more natural and comfortable, once the fabric of the room is saturated with energy, and it emits a comfortable, radiant heat. It also reduces humidity, as well as improves the air quality within a building, reducing the amount of circulating dust. In fact, in an independent performance review, CCIR provided the same levels of comfort within a room, using 60% less energy than a standard electric convection system, and on a par with ASHPs. Heating solutions for a low-carbon future While there is a real urgency, when it comes to decarbonizing heat, it’s vital to consider which technologies offer the most benefits to the end user. By understanding and investigating all of the alternatives to gas central heating, such as CCIR, the benefits will not only be felt in the short term, they are a sustainable solution for the longer term.
In today’s world, we spend almost 90 per cent of our time indoors, in our workplaces, leisure areas and our homes. It is no secret that the built environment has been relatively slow in its embrace of information technology and automation. According to KPMG’s ‘Building a Technology Advantage’ report, fewer than 20 percent of construction and engineering executives, and major-project owners said they are re-thinking their business models, so as to incorporate new technology. Yet, it has now become a necessity, as energy efficiency becomes a more prominent topic discussion, which is leading to sweeping changes across all aspects of our lives and none more so than in the built environment. Commitment to net-zero emissions Governments are beginning to impose tighter restrictions on building use, energy consumption and emissions. Policymakers around the world are committing to net-zero emissions targets, with more than 60 countries pledging to achieve carbon neutrality by 2050. For example, the European Union (EU) is committed to become a carbon-neutral economy, with net-zero emissions by 2050 and all new buildings within the EU must be constructed as near-zero energy buildings. Meanwhile, China has legislated that at least 30 per cent of all new buildings must be ‘green’. Smart technology to better manage HVAC Technology can help optimize energy consumption and create energy efficiency in our buildings Given this new trend towards energy efficiency in the real estate sector, smart technology is needed to better manage HVAC and energy consumption. Buildings currently contribute 40 per cent of global carbon emissions, a problem exacerbated by extreme weather conditions across the globe, which increases demand for electricity, as more people rely on air conditioning for cooling. Technology can help optimize energy consumption and create energy efficiency in our buildings, alleviating many of the problems that we have today. Technology enabled by the Internet of Things (IoT) can optimize comfort and safety, while providing remote operability and access to everything from HVAC systems to security cameras. At the same time, data collection and integration with cloud-based services allow for powerful energy efficiency measures. Designing and operating Smart buildings The concept and operation of smart buildings is not new. Architects and developers have been installing separate systems to control lighting and HVAC for decades. Later systems have evolved and helped building managers control access to different areas of a site, mitigate fire risk and protect against power surges. What is new is the addition of web-based platforms, in order to allow these verticals to integrate seamlessly with each other. The building of tomorrow is achievable today, using the latest in automation intelligence to control lighting, air-conditioning and heating. With these digital solutions, everything can be controlled remotely and allow for complete control, whenever it is needed most. Increased use of smart technology The first step in managing HVAC energy is to understand exactly how much is being used and where it is used. With this information at hand, managers can highlight areas for improvement, which in turn will help a building become more efficient and ultimately, save money. Another step in managing HVAC energy is including smart technology alongside your system Another step in managing HVAC energy is including smart technology alongside your system, as it can minimize maintenance costs. Predictive fault-finding can save maintenance time and labor, as well as minimizing downtime for expensive equipment or services. It is estimated that smart-enabled predictive maintenance is three to nine times cheaper than a traditional reactive approach. Tenant and occupant satisfaction are often also higher, as systems that experience failure can be identified, repaired and re-booted quickly. Smart building systems Smart building systems, such as ABB i-bus KNX ClimaECO and ABB Cylon BACnet solutions, can combine HVAC in one holistic solution, from central control and management of heating and cooling systems, down to room-level automation. Smart systems simplify the implementation of intelligent automation in modern buildings and using pre-installed algorithms, can make autonomous decisions on things, such as adjusting lighting and HVAC levels, to reflect time of day, external environment, occupancy levels or other variables. Additionally, data collection and data analysis enabled by IoT allows for increased knowledge and better predictions of use. Working with a smart building, which is interconnected, can act and learn on this data, while providing remote access to data and analytics for human oversight. The ROI of smart technology implementation In addition to legislation driving change, being ‘smart’ provides other real benefits for developers and owners. As a building adapts to the demands of its users or the goals of its managers, it can save energy, cut emissions and reduce energy costs. More effective and efficient use of power can save money, quickly repaying initial technology expenditure Comparing energy savings to the falling cost of installing a basic smart management system, smart buildings immediately prove their worth. According to HSBC, if a smart system delivered an energy cost saving of 25 per cent, on an installation cost of US$ 37,500, for a 50,000 sq. ft building, the annual savings could be as much as US$ 23,000, giving a payback period of less than two years. More effective and efficient use of power can save money, quickly repaying initial technology expenditure. HVAC and lighting alone can account for about 50 per cent of energy use in an average commercial building, but by incorporating smart automation, managers may see decreased energy costs of up to 30 to 50 per cent. Leading the fight against climate change Technologies, such as IoT and Artificial Intelligence (AI) are crucial to help us in the fight against climate change. These technologies help users, owners, operators and facility managers interact with the buildings of the future effortlessly, with personalized comfort and maximum efficiency. Artificial Intelligence and IoT is constantly in a state of evolution, as more applications for the technology are discovered. Given the ever-changing nature of technology, the possibilities for smart buildings in the future are endless.
A quick glance at official COVID-19 mitigation guidance reveals that it promotes increased ventilation air change rates, as the most effective way to keep people safe. Sounds easy, doesn’t it? Just open a window or turn up your ventilation system, if you have one. The fact is, however, that the vast majority of domestic properties in Britain does not have a mechanical ventilation system and rely on natural means for background ventilation, including windows, trickle vents or air bricks. In short, homeowners or tenants must physically open windows, after having decided whether they want to. This is an imperfect system for several reasons. Firstly, cold or wet weather might lessen an open window’s appeal and secondly, natural ventilation is a weather dependent process, as sometimes there’s simply no air movement. In other words, a natural ventilation strategy does not guarantee effective ventilation. With an airborne virus still being transmitted across the country, it’s important to understand the best options available to combat the spread. Building to minimum standards Building using a strategy that comprises natural background ventilation is the simplest, easiest and cheapest method of compliance to Part F: Building Regulations. That’s why it is the most common. We call this building to ‘minimum standards’. The problem with this approach, which is perfectly legal and entirely acceptable to Building Control, is that it often leads to problems caused by insufficient ventilation, such as condensation, mould, dust mites and odors, once the building is occupied. This issue has been made far worse, in recent years, since we committed to the 2050 Climate Change Targets This issue has been made far worse, in recent years, since we committed to the 2050 Climate Change Targets and started retrofitting insulation improvements to millions of existing properties. Our already well-sealed properties were sealed up even further, thereby causing all the moisture and pollutants produced by the occupancy to stay in the house, unless ventilated away. Pros and cons of positive input ventilation Positive input ventilation (PIV) is a highly effective means of dealing with such issues. PIV systems can be retrofitted into existing buildings, in order to improve the rate of background ventilation and eliminate the problems mentioned earlier. PIV is widely accepted in social and private housing, because it is unobtrusive, not behavior dependent, easy to install, highly cost effective and improves building energy efficiency. PIV can, therefore, help increase air change rates for naturally ventilated buildings. Unfortunately, however, new problems can emerge through the use of such systems. Increasing ventilation can create thermal comfort problems, leading to expensive heating bills and uncomfortable occupants. Rise in outdoor pollution ingress It can also increase outdoor pollution ingress, which, in turn, can exacerbate health issues and lead to deadly asthma triggers, as confirmed by the ruling in the Ella Kissi-Debrah inquest. In short, PIV and other ventilation strategies, despite comprising filtration, can still let pollutants in. On top of these issues is viral particles emitted indoors, a key concern in the current climate, which can be displaced faster by more air changes and are not easily destroyed. This arguably means the rate of transmission remains high. What is needed is a retrofit solution that achieves all the benefits of PIV, while removing and destroying indoor and outdoor pollutants, including viral/microbials. Active PIV is that solution. Active PIV: A huge step forward Active PIV with Photohydroionisation (PHI) increases fresh air ventilation air change rates Active PIV with Photohydroionisation (PHI) increases fresh air ventilation air change rates, thus reducing indoor humidity and providing safe, and effective active air purification throughout the indoor environment. Most importantly, it complies with COVID-19 mitigation guidance and removes, and destroys pollutants from both indoor and outdoor sources, including odors, VOCs, radon and other gases, allergens, such as pollens, mould, pet dander and dust mite faecal matter, particulates, including smoke or traffic soot, and viral/bacterial emissions, including SARS-CoV-2, at the point of transmission. This level of protection is not possible with increased ventilation alone or passive air treatments, such as filtration, UV, PCO, or ionization. Active PIV, therefore, provides an extra layer of indoor protection, over and above PIV that is continuous and not behavior dependent. PHI technology delivers active air purification The PHI technology that delivers active purification essentially mimics Earth’s natural air cleaning processes. Minute concentrations of ionized hydro peroxides are created, whenever there is sunlight, water vapor and oxygen present. These active molecules break down and destroy pollutants on contact, and revert back to water vapor and oxygen afterwards. Active PIV recreates this process in an indoor setting, constantly replenishing new active molecules to replace the spent ones. It is perfectly safe to breathe and effective against all three categories of indoor air pollutants, including: Particulates Microbial Gases Active PIV to counter COVID-19 pandemic Active PIV is the perfect innovative response to the COVID-19 pandemic. It can be easily and quickly retrofitted, and its effect is instant. For social housing managers, it delivers the best possible protections to the indoor spaces, which are occupied by the tenants for whom they are responsible. In terms of both its innovation and effects, Active PIV technology is the breath of fresh air that the ventilation industry and a pandemic-stricken world sorely needs.
A focus of research and development in the HVAC arena has been to develop alternative materials and technologies that requires less energy to function while still providing a benefit to regulate temperature. More passive approaches to regulating temperature offer green benefits and yield new components in systems to regulate temperatures in the future. Here are some examples and a glimpse of what’s to come. Phase-change materials have drawn interest because of their ability to change their physical state depending on the temperature in the environment. When PCMs store heat, they convert from solid to liquid, and vice versa when they release heat. Providing scalable opportunities Phase-change material (PCM) composites can regulate the temperature inside buildings using a simple and cost-effective manufacturing process. The composites can be added to building materials such as paint or can be 3D-printed as home accents to integrate into indoor environments. By augmenting climate control strategies, they can help to lessen the burden on struggling power grids. These materials are passive components that require no electricity to regulate temperature Using the PCM composites provides scalable opportunities to regulate temperatures passively in both new buildings and existing structures. These materials are passive components that require no electricity to regulate temperature. Researchers at Texas A&M University combined light-sensitive liquid resins with a phase-changing paraffin wax powder to create a new 3D printable ink composite. Broader temperature ranges Using a light-sensitive resin, they cured it with an ultraviolet light to solidify the 3D printable paste. In the future, researchers will experiment with various phase-change materials that operate at broader temperature ranges and manage more thermal energy during a given cycle. Cooling chips made from bismuth telluride have applications in air conditioning and refrigeration. When electrical current runs through the chips, it removes heat, allowing one side of the chip to cool while the other side heats up. Phononics is a Durham, N.C., startup that has secured $50 million in funding from Goldman Sachs Asset Management to develop the approach. Cooling outdoor installations The funding will be used to build out high-volume manufacturing in North Carolina and in Thailand It’s a versatile technology that enables small or large chips that can be used to deliver the coolant effect needed for compact freezers, for air conditioning, or to prevent overheating of laser-based sensors in autonomous cars or optical transceivers to transmit 5G data. In the future, there are possible applications in cooling mattresses, motorbike helmets, and cooling outdoor installations. The funding will be used to build out high-volume manufacturing in North Carolina and in Thailand. An advantage of the approach is that there is no impact on global warming, unlike traditional vapor compression systems. Although bismuth telluride powder is toxic, it is benign when manufactured into chips, and can be safely recycled or disposed of. Light-Colored material An associate professor at Northeastern University in Boston has created ‘cooling paper,’ which enables a building or home to essentially keep cool with no electricity required. The paper, which is recyclable, reflects heat away from rooftops and removes heat from homes and buildings. The paper can cool down a room’s temperature by as much as 10 degrees Fahrenheit. The invention works through the porous microstructure of the natural fibers inside the cooling paper, which absorbs warmth and reemits it away from the building.

‘Net zero’ is an unavoidable reality in the continuing fight against climate change. For example, both the United Kingdom and the European Union have set targets of having net-zero greenhouse gas emissions by 2050. These objectives are in line with a commitment to global climate action under the Paris Agreement. Net zero - carbon neutral Net zero refers to the balance between the amount of greenhouse gas produced and the amount removed from the atmosphere. It’s another term for ‘carbon neutral’. Any activity that creates carbon emissions must be offset by corresponding actions that remove an equal amount of emissions. Examples might be to plant trees that remove CO2 from the atmosphere or to re-purpose emissions-free energy for additional uses. For the HVAC market, the goal of net-zero emissions presents a variety of challenges For the HVAC market, the goal of net-zero emissions presents a variety of challenges. More than 40% of today’s CO2 emissions come from buildings and 30% of energy in buildings is wasted. According to a 2018 International Energy Agency (IEA) report, around 20% of the electricity used in buildings is related to HVAC, and the number is set to more than triple by 2050. Connected systems and real-time data analytics Fortunately, the HVAC industry has developed technology tools to address the challenge, including real-time data analytics and connected systems, to scrutinize how and where energy is being used, and to optimize efficiencies and building performance. In addition to helping to eventually achieve net-zero emissions, these activities will also provide cost savings. The 2020 COVID-19 pandemic shutdown highlighted the potential impact of lowering greenhouse gas emissions. During the pandemic, global greenhouse gas emissions declined by 7% compared to the previous year, according to research from the University of East Anglia, the University of Exeter and the Global Carbon Project. However, the emissions have resumed as global economies have recovered. Public-private cooperation to achieve net-zero emissions Achieving net-zero emissions will involve many stakeholders and will require public-private cooperation that includes local governments, building owners and other businesses. Part of the solution is regulation, as governments encourage construction of green buildings. Meeting the objectives involves not just internal systems and infrastructure in a building, but also the materials used, including options, such as smart glass windows and solar panels. There is also an opportunity to educate the public on the positive role that buildings, including HVAC systems, can play in the campaign to eliminate climate change. The public often associates pollution with vehicle exhaust, for example, and may not realize the role that building systems can have on the environment, for better or worse. Leveraging technology to reduce emissions Leveraging technology to reduce emissions in the buildings sector can have a positive impact on the environment Leveraging technology to reduce emissions in the buildings sector can have a positive impact on the environment and on public opinion of the industry’s role to achieve green goals. The role of the HVAC industry should not be overlooked. There are resources available to help guide the path. For example, the Leadership in Energy and Environmental Design (LEED) green building certification program provides a rating system that covers the design, construction, operation, and maintenance of buildings worldwide. U.S. Federal, state and local governments are positioned to require or reward LEED certification, including tax credits, zoning allowances, reduced fees or expedited permitting. building energy efficiency and electrification US President Joe Biden has also announced an initiative to invest federal dollars in building energy efficiency and electrification, with a goal of modernizing and upgrading the nation’s buildings to be affordable, resilient, accessible, energy-efficient, and electrified. Fortunately, manufacturers in the HVAC market as a whole are focused on providing energy-efficient and sustainable technologies to drive the net-zero future of the industry.
High school seniors and their parents weigh multiple factors, when choosing a college or university. In the aftermath of the COVID-19 pandemic, the importance of one factor has shown a marked increase. Indoor air quality (IAQ) is now among the top-three aspects that an applicant and their parents would consider, when choosing a college, according to one survey. Growing awareness of IAQ Growing awareness of IAQ presents an opportunity, as the HVAC industry seeks to serve the higher education market. If air quality is a deal breaker for new students, the opportunity is that much more urgent. A recent survey by professional services firm, JLL confirms that health and safety is at the top-of-mind for parents, and their high school seniors. Some 48% of surveyed parents ranked campus cleanliness and indoor air quality among the top-three most important factors, when choosing a college or university. Campus cleanliness and indoor air quality Also, a total of 84% of parents rank cleanliness and indoor air quality as either ‘important’ or ‘somewhat important’. Campus cleanliness and indoor air quality (IAQ) ranked behind ‘quality of academics’ in the top spot and ‘affordability’ in the second position. Before the COVID-19 pandemic, it is unlikely that health and IAQ concerns would have even been mentioned in such a survey Before the COVID-19 pandemic, it is unlikely that health and IAQ concerns would have even been mentioned in such a survey. The high ranking of the issue in the current survey reflects heightened health concerns, brought on by the pandemic. In fact, 42 percent of parents noted in the survey that their sentiment toward campus cleanliness and indoor air quality increased, as a result of the COVID-19 pandemic. “Students and staff on campus will continue to demand transparency and the highest standards around cleanliness, and air quality,” said Ron Gregory, Executive Vice President North America, JLL Higher Education. Environmental sustainability Environmental sustainability has also emerged as a factor in student recruitment. Some 21% of parents have become more interested in an institution’s commitment to sustainability, during the pandemic. Poor ventilation systems became a big concern, as COVID-19 virus spreads through educational institutions and other facilities. HVAC has gained a higher profile, as a factor that can help to mitigate the spread of the virus. Retrofits can make the difference In the HVAC market, newer systems tend to be more environmentally sustainable and can ensure compliance with the latest regulatory requirements. However, even retrofits can make a difference, especially ‘deep retrofits’ that can address concerns about circulating outside air, increasing humidity and improving filtration systems, as older buildings seek to become greener. Broadly speaking, poor IAQ can negatively affect the health and learning of students of any age Broadly speaking, poor IAQ can negatively affect the health and learning of students of any age. The presence of mold, for example, can increase risks of asthma and other respiratory diseases. Students in well-ventilated classrooms have been shown to achieve higher scores on standardized testing. Greater concern about IAQ and the risks of COVID-19 virus spread have combined to provide new business for HVAC companies that offer useful tools, in order to increase ventilation and even kill germs. Importance of preventative maintenance Keeping campuses clean also impacts a family’s perception of a campus. Some 86% of parents rank the ‘look and feel’ of a campus, as either ‘important’ or ‘somewhat important’. Also, 88% of parents say the physical condition of buildings is either ‘important’ or ‘somewhat important’. As a component of a campus’s physical presence, HVAC systems are part of the solution, when seeking to ensure a campus is seen as modern and appealing. Preventative maintenance is also a factor, in HVAC as well as generally speaking. “Savings generated from preventative maintenance can go back into facilities upkeep, creating an overall better, cleaner and more modern experience for students,” said Kevin Waver, President of JLL Public Institutions at JLL.
St. Vincent Fishers Hospital in Fishers, Indiana is part of the largest Catholic, a not-for-profit healthcare system in the United States of America. It serves its community, not only by providing the utmost in compassionate care, but also by implementing excellence in environmental stewardship, by obtaining LEED certification, under the healthcare rating system, and by being the first hospital in Indiana to do so. This explains why, in 2013, when St. Vincent Fishers Hospital needed to expand its emergency care clinic, to a full-service in-patient care hospital, it adopted its vision statement - ‘Expansion with the environment in mind.’ And why, when it came to its heating, humidification, and sterilization needs, St. Vincent Fishers Hospital chose to install Fulton boiler equipment. Fulton boilers Acting on the advice of Kevin McNutt of BSA LifeStructures, consulting engineer on the project, and working with Fulton representative and product specialist Byron Koch, President of A.B Young Company, St. Vincent Fishers Hospital installed: Three dual-fuel Fulton Vantage (VTG-2000DF) high-efficiency condensing hydronic heating boilers, and Two Fulton Classic (ICS-20) vertical tubeless steam boilers. In 2015, the ICS-20s, used for humidification only, were upgraded to two (bigger) Fulton Vertical Multi-Port (VMP-50), low-emissions, dual-fuel steam boilers. These boilers back-fed the existing surgery suite for sterilization and then, re-fed St. Vincent Fishers Hospital’s need for humidification, serving a much greater overall load. Vantage hydronic boilers installed The Vantage boilers are dual-fuel optimized for both, natural gas and No. 2 fuel oil The three installed Fulton Vantage hydronic boilers, as fully condensing boilers, achieve higher thermal efficiencies, of up to 99%, by recovering the latent heat of condensation from their own exhaust gases. The Vantage boilers are dual-fuel optimized for both, natural gas and No. 2 fuel oil. In fact, Vantage is the world’s first condensing boiler to offer full-time operation on No. 2 oil as a secondary fuel. Featuring Fulton ModSync controller The Vantage boilers were also installed with a Fulton ModSync controller, to offer outdoor reset and BACnet communication, to maximize system efficiencies, based on seasonal temperatures and integration with building software systems. Senior Mechanical Engineer at BSA LifeStructures, Kevin McNutt said, “Our firm has incorporated Fulton Vantages for hospital boiler plants, for at least the past 10 years, because of their ability to drop the heat and hot water temperature, so that we could get the condensing out of them, for energy savings. Also, there is a dual-fuel feature that we need for healthcare.” Dual-fuel on a condensing boiler Kevin McNutt adds, “We arrived at Fulton, because it’s a quality product, number one and number two, because you (Fulton) were the only ones who would provide dual-fuel on a condensing boiler, for a long time. Fulton products were used to generate cost savings, to generate more LEED points, to be more sustainable with hot-water heating systems.” I like how easily accessible the Vantage is for routine maintenance and safety checks" Matt Todd, Power Plant Specialist at St. Vincent Fishers, said “When it comes to the day-to-day operation of the Vantage boilers, I like how easily accessible the Vantage is for routine maintenance and safety checks.” Matt Todd adds, “In the two years, since I have been here, I haven’t had enough issues (with the Vantages) that I can be specific enough about, to complain about. The squeaky wheel gets the oil, as they say, but (the Vantages) haven’t made much noise at all. They have been wonderful boilers.” Vertical Multi-Port boilers (VMP-50s) While the Vantage hydronic condensing boilers were standalone boilers, the two Vertical Multi-Port boilers (VMP-50s) were shipped and installed, as part of a fully-skidded system. This system included a boiler feed unit, a 304 stainless steel tank and blow down separator, and a ModSync controller, in addition to the VMP’s dual-fuel and low-NOx capabilities. Kevin McNutt stated, “The first set (of ICS-20s) was ordered from Fulton in a three-skid arrangement, and those were installed without issue. What’s compelling about this story is that, a year down the road, when we decided that we needed to replace these boilers, to address long-term sterilization use, we replaced them with Fulton VMPs that were able to pass through standard door-sized openings, so that they could be easily installed on-site.” Byron Koch commented, “The very tight space of the boiler room presented an installation concern, but luckily the VMP system shipped as multiple units that broke down into sections. Moreover, the only way we could get the boilers installed in the limited space we had, was because of the vertical design of the boilers, which allowed them to fit, where other types of boilers, like horizontal fire tube and water tube, would not.” VMP boilers perform critical hospital functions Energy savings and installation is easy, as the VMP boilers at St. Vincent Fishers perform critical hospital functions Energy savings and installation is easy, as the VMP boilers at St. Vincent Fishers perform critical hospital functions, such as controlling the temperature and humidity in the surgery rooms, which helps maintain infection control. This can literally mean the difference between life and death. In fact, so critical is the function of boilers in helping maintain infection control in hospitals that the 2013 edition of the American Society of Heating, Refrigerating and Air-Conditioning Engineers’ (ASHRAE) HVAC Design Manual for Hospitals and Clinics devotes an entire chapter to it. In addition, they acknowledge the importance of installing boilers in hospitals that are low- maintenance, energy-efficient, and reliable. energy-efficient heating solutions Matt Todd stated, “In addition to sterilization and comfort needs, we feed our hospital humidifiers, with our Fulton Vertical Multi-Port (VMP) boilers and they, in turn, feed our operating room, which has to be in the range of certain specs, usually 30 to 60% (humidity).” He adds, “If out of range there, you have downtime in Surgery and the ER. So humidification plays a big role in it too and that includes our Labor and Delivery C-section room that also has the same strict humidification requirements.” Matt Todd concludes, “At St. Vincent, patients are always the number one priority, but number two is the power plant and the boilers that are installed in there. They (the boilers) heat the building, humidify our air and also sterilize our equipment. They are critical to patient care. We have to have them and Fulton has done a great job in helping us fulfill that need.”
An innovative air conditioning solution from Carrier is helping to ensure optimal ventilation and comfort in the historic Raphael Rooms. During a typical summer, the temperature in Rome can soar as high as 104°F/40°C, deciding to install air conditioning in the Raphael Rooms for the first time is an easy one. To meet the unique needs of the historic space, Carrier engineers developed and installed a custom solution utilizing a new system design that delivers heating and cooling in one-quarter of the traditional footprint, all without altering the existing historic infrastructure. Carrier, a pioneer in high-technology heating, air conditioning, and refrigeration solutions, is a part of Carrier Global Corporation, the global provider of healthy, safe, sustainable, and intelligent building and cold chain solutions. Preserving the artwork “The Vatican Museums have the mission to ensure the protection and safety of the artwork, spaces, and visitors. Carrier was extraordinary because, like its prior work at the Sistine Chapel, the team knew how to work with our technical divisions and how to update these rooms that were not conceived as a museum,” said Barbara Jatta, Director, Vatican Museums. “The result not only helps us in our preservation mission for the future generations but also helps in the enjoyment of this heritage frequented daily by numerous visitors, more than 6 million every year.” Developing innovative solutions This project underscores our role in the industry, who has the expertise to develop unique, customized HVAC solutions" “It was a tremendous honor to be asked again by the Vatican Museums to deliver innovative solutions. This project underscores our role as a leader in the industry, who has the expertise to develop unique, customized HVAC solutions,” said Didier Genois, Vice President and General Manager, Carrier HVAC Europe. “We put our world-class engineering and design resources into this project and are exceptionally proud of the outcome.” Installing fan coils and chillers The right solution for the space had to be installed without impacting any of the historic elements within the rooms but would still function to deliver proper ventilation and maintain comfortable temperatures. The Vatican Museums again turned to Carrier, who in 2014 installed an innovative HVAC system at the Sistine Chapel. Carrier engineers specifically designed small, yet high-capacity, fan coils to circulate the air, which was installed underneath the windows in the Raphael Rooms, remaining invisible to visitors. Energy-efficient Carrier AquaSnap 30RQV chillers were also installed in a location unnoticeable to visitors, and an iVu building automation system is now in place to help optimize the HVAC systems to deliver a healthier, safer, and more efficient indoor environment for visitors. Solutions according to requirements “The space available for equipment inside the Raphael Rooms was very reduced. We had to design a small 2.5 kW fan coil but with 10 kW of capacity, a powerful piece of equipment. This solution is unique because this type of product did not exist. We had to imagine and develop a product that would fit this function in a reduced space,” said Michel Grabon, Director, Carrier AdvanTEC/Building Solutions Group Europe. Adorned with frescoes painted between 1508 and 1524 by Renaissance artist Raphael, the Raphael Rooms are universally known as one of the greatest works of art ever created, and a video highlighting the project can be found.

Desiring to offer a community center to its residents, the Town of Oro Valley purchased a facility with existing membership. The Town identiﬁed within this facility that the building systems were inefficient and at the end of their useful lives, and the facility’s energy consumption was high. Facility infrastructure upgrades With no funds immediately available, the Town of Oro Valley was challenged to move forward with facility improvements and infrastructure upgrades following acquisition. “There is a considerable focus on efficiency and conservation in the community, so that served as a major tenet for us as we considered upgrades,” said Stacey Lemos, the Chief Financial Officer for the Town of Oro Valley, adding “Another challenge we had was that this is a living and breathing facility, with no signiﬁcant seasonal slow times and events to work around.” Preliminary energy assessment Trane conducted a preliminary energy assessment, walking through the facilities to gather information Based on a previous relationship with Trane for mechanical systems maintenance, the Town of Oro Valley was interested in creative solutions that the company might provide. Trane conducted a preliminary energy assessment, walking through the facilities to gather information. Using a State of Arizona cooperative contract, Oro Valley selected Trane as their energy services company (ESCO). Identifying energy saving opportunities, The Town of Oro Valley entered into a performance contract with Trane, which would allow the Town to pay for upgrades, with the energy savings realized from the project. The Trane team conducted an investment grade audit (IGA) to thoroughly evaluate the entire facility, including the 50,000 sq. feet building, tennis courts, and golf courses. Energy conservation measures (ECMs) Trane deﬁned potential energy conservation measures (ECMs) designed to reduce consumption of electricity, gas and water. This holistic approach would provide Oro Valley with their desired energy savings solutions, while maintaining a budget neutral project. Improving efficiency and comfort, by creating revenue opportunities, Trane replaced thirty-ﬁve HVAC packaged units with more energy efficient systems that feature multiple-zone cooling, to meet comfort demands of staff and guests. LED lighting installed throughout the facility To reduce energy use and improve lighting quality, LED lighting was installed throughout the facility, including more than 250 ﬁxtures on the tennis courts, six wall mounts in the racquetball viewing area, and ﬂood lights near the pool. With the new ﬁxtures, the center can now better accommodate revenue generating events, such as area tennis tournaments. Trane helped reduce water consumption with equipment and controls integration. With its location in the desert, water conservation also was a key issue for the facility. Trane analyzed industry data regarding use per acre-foot standards, to evaluate water use at the golf courses and presented solutions to reduce consumption. Trane Tracer SC building automation system (BAS) The new pumping station uses variable speed pump motors to help reduce energy use The north pumping station was replaced early on in the project, due to an unexpected mechanical failure. The new pumping station uses variable speed pump motors to help reduce energy use, along with a Trane Tracer SC building automation system (BAS), to enable connectivity to the remote pumping equipment. The existing south pumping station was retroﬁtted with a Tracer SC and both irrigation pumping stations were integrated into a new Tracer Ensemble Enterprise Building Management System. Access Multiple sites from single web-based interface The Tracer Ensemble Enterprise Building Management System enables The Town of Oro Valley to easily access multiple sites and equipment from a single web-based interface. It also allows Trane to monitor, trend and validate water consumption in real time, identifying savings opportunities. The swimming pool pumping ﬁltration and heating systems were replaced to reduce maintenance and chemical costs, eliminating the chlorination system, while improving overall operation. A new pool cover was also installed to reduce water evaporation and heat loss in the cooler months. The signiﬁcant water use reduction achieved by the upgrades was a key factor in enabling the project to remain budget neutral. Trane Air-FI wireless mesh network The community center BAS was also integrated to the building management system and HVAC controls were installed using Trane Air-FI wireless mesh network with Zigbee/BACnet communication protocol. With no wires to run and all unit controls prepackaged and programmed, Trane technicians were able to spend less time on installation and more time educating facility managers on the use of the controls and the Ensemble building management system. Ensemble building management system The web-enabled Ensemble building management system provides an enterprise view of the entire facility The web-enabled Ensemble building management system provides an enterprise view of the entire facility, allowing facilities managers to handle daily tasks, create schedules for the varied spaces in the center, manage alarms and make adjustments from anywhere in the building, or remotely with a tablet or phone. The Town of Oro Valley also has the option to integrate its other existing control systems into the system in the future. “For the comfort of our guests, our systems have to be reliable,” said Stacey Lemos adding, “We have workout facilities, a restaurant, a pool; schedules vary and some spaces need more cooling than others. With customized thermostats and enterprise-wide monitoring and control, we are now better able to keep our temperatures where they need to be.” Broad scope of ECMs Entering into a performance contract to use guaranteed energy savings to pay for needed upgrades, the Town of Oro Valley and Trane implemented a broad scope of ECMs, which are designed to enhance comfort, improve operations and reduce energy costs. The upgrades, which included improvements to HVAC, controls, lighting, swimming pool systems, golf course irrigation and domestic hot water conservation, are exceeding expectations, providing more than US$ 68,700 in energy savings and more than US$ 93,500 in water savings costs annually. Energy efficiency with LED lighting The Town has also realized more than US$ 30,000 in utility rebates. In addition, the Town of Oro Valley was honored by Tucson Electric Power for improving its energy efficiency, by replacing inefficient lighting with LED bulbs, and helping to make the community more sustainable by harvesting rain water and deploying a Green Team. “We are meeting projections, and have been able to keep to our budget,” said Stacey Lemos, adding “Plus, the useful life of the equipment will far exceed our debt.”
Round table discussion
A long list of regulatory and environmental trends is determining the future of the HVAC industry. Some trends will have an immediate impact, while others will come in force years from now, although the complexity of the industry requires that manufacturers and installers start planning now. We asked our Expert Panel Roundtable: What regulatory or environmental trend will have the greatest impact on the HVAC market?
The practice of working from home soared during the coronavirus (COVID-19) pandemic and many observers see a likely continuation of the trend, as infection risks gradually subside. Both environments – home and office – depend on HVAC systems to keep occupants comfortable (and safe!). Therefore, the industry stands to be impacted whichever way the trend plays out. We asked our Expert Panel Roundtable: How will remote working affect residential and commercial HVAC?
The Internet of Things (IoT) is the network of physical objects embedded with sensors, software and other technologies to facilitate connecting and exchanging data with other devices and systems over the internet. Use of the IoT is expanding among both business and residential applications. However, there are hurdles to overcome, including security, privacy and networking challenges. As more HVAC devices embrace the IoT, we asked our Expert Panel Roundtable: What is the impact of the Internet of Things (IoT) on the HVAC market?
