Pandemic recovery is top-of-mind for so many cities, but a return to the normalcy which in 2019 might not be enough to maintain secure, connected, and resilient communities in this new world. As shared during the presentation at the IoT Global Innovation Forum, cities must reimagine their current infrastructure models and envision a connected, holistic future for the community. By integrating IoT technologies and connected building solutions, cities can build environments that are individual to their community's health and sustainability goals. In fact, according to the Johnson Controls Energy Efficiency Indicator Survey, 85% of organizations are already investing in smart building technology to reduce energy costs. Creating Data-Driven Communities Connected environments are better equipped to maintain occupant safety, handle the next public health crisis, and are key to driving the sustainability goals of individual businesses and the overall community. The smart infrastructure allows previously siloed entities to connect and share data across platforms The smart infrastructure allows previously siloed entities to connect and share data across platforms, providing building owners and facility managers with the information to make data-driven wellness decisions for the benefit of the community. From waste-water reduction to touchless access control, to clean air solutions, to cloud-based remote monitoring, healthy building infrastructure impacts environments in ways that ripple throughout the larger community and impact the planet. Smart Infrastructure in Action For instance, the Housing Authority of the City of Pueblo, CO partnered with Johnson Controls and GRID Alternatives to install a community solar garden that will drive energy efficiency and sustainability goals. The Photovoltaic (PV) system, composed of ground-mounted solar panels, will generate enough energy to power 200 households annually. The project also created affordable housing options for the community, with the increased energy capacity being allocated to a mix of qualified, low-income residents as well as multifamily affordable housing properties. The City of Pueblo’s renewable energy initiative will also deliver green jobs with hands-on solar training for the local community, ensuring long-term economic development. With this trifecta of community improvement outcomes, the City of Pueblo is a model of how cities can build community resilience while strengthening their infrastructure. Smart, connected and healthy environments are better equipped to maintain occupant safety and drive the sustainability goals of individual businesses and the community.
A number of standard unit coolers from Friga-Bohn, which supplies a wide range of market-leading refrigeration solutions to the food industry, are 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 in place for new installations using refrigerants with a GWP (Global Warming Potential) of more than 2500. 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 refrigerant Friga-Bohn can confirm that a number of its unit coolers offer compatibility with new A2L refrigerants CO2 has become the preferred refrigerant in high-capacity refrigeration installations due 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. To ensure simplicity of choice for installers, Friga-Bohn can 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. A2L-compatible coolers The A2L-compatible coolers 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. 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. A2L refrigerants provide the opportunity to reduce environmental impact and comply with the F-Gas regulation 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. Transitioning to 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.
TROX, a globally renowned manufacturer of high-quality ventilation equipment, has re-joined the association, Eurovent Middle East, after a year of absence, renewing its commitment to joint industry initiatives, in the fields of standardization, education and raising awareness. TROX has been active in the Middle East for over 50 years, providing ventilation equipment to a wide range of prestigious projects. efficient ventilation solutions In light of the increasing importance of adequate and efficient ventilation solutions, and the role of Indoor Air Quality (IAQ) for general health and safety, the industry needs to reinforce its focus on technical regulations, standards and recommendations, in the fields of ventilation and air filtration. Being part of an industry association allows for pooling of resources and a coordinated approach to the transformation of markets, towards higher standards. TROX, an advocate of high standards in airside products We currently see how dependent we all are on the supply of safe and clean indoor air" Saad Ali, Managing Director of TROX Middle East and Africa, underlines the importance of representing the HVAC voice in the region. He said, “TROX has always advocated for the highest standards in airside products. We currently see how dependent we all are on the supply of safe and clean indoor air.” Saad adds, “While the technical solutions and equipment are available, we need to bring about change in the awareness and knowledge of people, that the technology is also made use of and implemented with certification. This can only work, if the industry stands together and jointly works towards higher standards and requirements.” Air Handling Units (AHUs) education program Nerissa Deoraj, Executive Director of Eurovent Middle East, said “We are happy to welcome TROX back, after a year of absence. We are currently developing an educational program for Air Handling Units (AHUs), among other relevant technologies and appreciate the expertise, and training capacity that TROX will add to this initiative.” Nerissa adds, “Educating stakeholders is the common responsibility of the industry and can only be achieved by working together.”
Carrier Transicold has raised the bar for electric auxiliary power unit (APU) performance with its new lithium-ion ComfortPro® electric model that delivers double the air conditioning runtime provided by some competitive conventional battery-powered APUs. Carrier Transicold is a part of Carrier Global Corporation, the pioneering global provider of healthy, safe, sustainable and intelligent building and cold chain solutions. “The new ComfortPro model is the first electric APU capable of providing cab cooling for extended periods formerly only achieved by diesel-powered units, thanks to its extended-capacity lithium-ion batteries and proprietary embedded power management system,” said Ryan Rubly, product manager, power management systems, Truck Trailer Americas, Carrier Transicold.Carrier Transicold will feature the lithium-ion ComfortPro APU among other electric technologies at the Advanced Clean Technologies Expo at the Long Beach Convention Center this month (booth 547). Key differentiators Key differentiators of the new APU: 7,500 BTU/hours of cab cooling that can double the runtime provided by some competitive absorbent glass mat (AGM) battery powered electric APUs, delivering continuous air conditioning that extends well beyond what is required for overnight rest breaks and up to 17 hours under certain real-world conditions. Quiet, emissions-free performance with relatively few moving parts, eliminating the maintenance required of diesel-powered APUs. Advanced lithium-ion technology, engineered specifically for long-haul commercial vehicle applications, provides an extremely power-dense and durable solution, charging faster with less performance degradation over time compared to conventional AGM batteries. Five-year lithium-ion battery warranty, providing more than twice the typical lifespan of AGM batteries and outlasting the truck trade cycle for many fleets. Reduced APU weight by 26% using two DOT-certified lithium-ion batteries compared to Carrier Transicold’s standard electric APU, which uses four AGM batteries. Lower cost of ownership than other APU alternatives thanks to its long-life batteries coupled with fuel savings and minimal maintenance requirements. ComfortPro All ComfortPro electric APUs include a power plant, an under bunk climate control unit and a programmable control panel, featuring Carrier Transicold’s exclusive Cabin Pre-Cool Lock that helps extend battery life by assuring the preferred cabin temperature is attained before the APU takes over. Available options add heating, power for hotel loads, shore power connectivity and truck engine preheating, so fleets and owner-operators can customize ComfortPro electric APUs to suit specific needs. APUs are used by the trucking industry to support cab climate control when the vehicle is stationary during driver rest periods, saving fuel, reducing engine idling and wear along with related emissions and providing regulatory compliance. The comfort and conveniences provided by APUs also help fleets with driver retention.
In an ever-changing environment like the data center, it’s most beneficial to have as many intelligent systems working together as possible. It’s amazing to think of how far technology has come from the old supercomputers the size of four filing cabinets to the present data centers that are pushing 1,000,000 Sq. Ft. Managing a Data Center’s Needs Historically, managing a data center was fairly straightforward. In all the growth, one finds digging into the nuisances of every little thing data center cooling, power, and rack space, among hundreds of other minute aspects. This is all way too much for a Data Center Manager to be able to manage and comprehend by themselves, so implementing systems that can talk to each other has become a must. When evaluating the cooling side of the infrastructure, there are real challenges that may make one want to consider hiring a team of engineers to monitor the space constantly. Most sensible room capacities vary constantly during the first year or two years of build-out. This creates a moving target for CRAC/CRAH systems to hit within precise setpoints, and this can create a lot of concern by data center managers about hot spots, consistent temperatures, and CRAC usage. Just when one thinks the build-out is done, someone in the team decides to start changing hardware and one is headed down the path of continuous server swap outs and capacity changes. It really can turn into a game of chasing the own tail, but it doesn’t have to. Reducing Stress Level Zone Control is the creation of open communication and dialogue between all units on the team Data Aire has created the Zone Control controller to address the undue stress imposed on data center managers. Zone Control allows CRAC and CRAH units to communicate with each other and deduce the most efficient way possible to cool the room to precise set-points. No longer will one need to continually adjust set-points. And as previously mentioned, it’s incredibly beneficial to have as many intelligent systems working together as possible. Zone Control is the creation of open communication and dialogue between all units on the team. CRAC & CRAH Units Should Work Together Just like in sports, all players on the team must know their own personal role and how all players doing their part creates the most efficient team. The 2018 winter Olympics makes one think about the similarities between a four-man bobsled team and how CRAC/CRAH units communicate through Zone Control. The bobsled team starts off very strong to give as much of a jump out of the box as possible. Then each member starts hopping into the bobsled in a specific order. Once they assume maximum speed, all members are in the bobsled and most are on cruise control — while the leader of the team steers them to the finish line. That’s Zone Control; the leader of the team. Personal Precision Cooling Consultant Getting back to data center cooling. When the units first start ramping up – they do so to ensure enough cooling immediately. Then as our controls/logic gets the readings of the room back, these units start to drop offline in standby mode to vary down to the needed capacity of the room. They are able to talk to each other to sense where the hotter parts of the room are to ensure the units closest to the load are running. Once they have gone through this process of checks and balances to prove the right cooling capacities, they go into cruise control as Zone Control continues to steer. Combine the Ultra with Zone Control and one has the smartest and most efficient CRAC system in the industry This creates the most efficient and most reliable setup of cooling in each individual data center possible. Data center managers don’t need to worry about trying to find hot spots or worry about varying loads in the room. Zone Control is an intelligent communication control that works with CRAC/CRAH data room systems to identify the needs of the space and relay that message to the team. Think of it as the personal precision cooling consultant that always has the right system setup based on real-time capacities. Add V3 Technology to the Zone Control Team One can go even a step further in the quest to have the most efficient environmental control system safeguarding the data center. Pair Zone Control with gForce Ultra. The Ultra was designed with V3 Technology. It is the only system on the market to include a technology trifecta of Danfoss variable speed compressors accompanied by an EEV and variable speed EC fans. gForce Ultra can vary down to the precise capacity assignments in the data room. Combine the Ultra with Zone Control and one has the smartest and most efficient CRAC system in the industry. The Zone Control even has the logic to drop all Ultra units in a room down to a 40% capacity and run as a team in cruise control, versus running half the units at 80% because of the efficiency written in the logic.
Hi-line Industries, an established and reputable UK manufacturer of high-quality compressed air purification equipment, can offer a cost-effective and proven way of meeting the ongoing demand for replacement compressed air filters. Rather than pay for expensive and often low-efficiency OEM filters, an increasing number are turning to Hi-line’s vast range of alternative elements, which frequently provide an ‘upgrade’ on competitor solutions at less cost. Cost savings Hi-line is not only renowned for its proprietary range of high-quality filter housings and energy-efficient elements, but its vast range of alternative elements to ‘upgrade’ and replace competitor products. There is no longer any need to pay a premium for replacement compressed air filters as Hi-line’s alternative range of flow elements can cost circa 60-70% less than those available from compressor manufacturers. When considering there could be four elements on one system, the saving is significant. High-performance Air filters Hi-line’s elements provide higher performance because the company upgrades the technology The alternative elements produced by Hi-line provide an exact match with the size and connection specifications of the originals. Hi-line’s elements offer at least the performance of the original, although in many cases they actually provide higher performance because the company upgrades the technology. For instance, Hi-line uses pleated filter media rather than wrapped as it offers four times the cross-sectional area of standard elements. The larger cross-sectional area provides several important advantages, including lower pressure drop, which in turn saves energy as the compressor does not have to work as hard to force air through the filter. Further benefits include higher contamination-holding capacity, longer service life, and greater flow characteristics - all for less financial outlay. Alternative filter elements Hi-line alternative filter elements with ‘pleated’ media allow the original housing to give users the high-performance, low-cost filtration features enjoyed by Hi-line filter elements. However, Hi-line can of course supply its own die-cast aluminum filter housings, which are subject to alu-chrome treatment on both external and internal surfaces, and finished (externally) with a tough epoxy baked-on paint in compressed air blue (RAL 5015). These treatments provide long-term protection, even when subject to the harshest of conditions. Availability Another major advantage of using Hi-line is availability. The company stocks alternative elements worth a total of more than £1 million at its Midlands factory, ensuring circa 167,000 filter elements/cartridges are available for next-day delivery and installation. The Hi-line sales team takes advantage of fully computerized cross-referencing software to ensure the swift turnaround of inquiries for same-day despatch.
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.
With the UK committed to reducing greenhouse gas emissions to zero by 2050, drastic action is needed by the government. For new-build homes, there’s a gas boiler ban coming in less than five years’ time. And for older properties, it’s likely that gas prices will continue to rise, to encourage homeowners to switch to a more sustainable alternative. Renewable heating market With this in mind, the renewable heating market is growing rapidly, albeit from a very small base – but with targets in place to keep the momentum up. The government has committed to install 600,000 heat pumps into new homes by 2028. The government has committed to install 600,000 heat pumps into new homes by 2028 People who are already living in (old and new) properties heated by renewable technology should be applauded for pioneering it – but understandably, not everyone has the confidence to give up a solution they’re familiar with, and to step into the relative unknown. And that’s why the value of transitional technologies cannot be over-estimated– both to homeowners who want to live more sustainably and to installers looking to adapt and future-proof their businesses. But the role that hybrid heat pumps can play in accelerating progress on the road to zero has been somewhat overlooked to date. Hybrid heat pumps Hybrid heat pumps combine the power of a heat pump with the familiarity of a high-efficiency boiler. The two appliances work together to provide heating and hot water, providing the ideal replacement for a combi boiler as a first step towards introducing renewable heating technology into the home. Compared to a traditional gas boiler, hybrid heat pump systems can reduce CO2 emissions by as much as 55% and have been proven to deliver up to a 50% reduction in energy bills in homes in the UK. Our Daikin Altherma hybrid heat pump’s smart programming helps to save up to 35% more energy than a traditional condensing boiler by automatically determining the most economically and energy-efficient operating combination based on energy prices, outdoor temperatures, and indoor heat capacity. Heat pump share The hybrid system’s operating mode can be shifted to more electric heat pump share As well as being quick to install, hybrid systems are designed to look and operate like a conventional boiler system and deliver like-for-like performance and comfort levels. And to give homeowners peace of mind, the heat pump can act as a back-up for the boiler, and vice-versa – meaning they’ll never be caught short. Hybrid systems are best-suited to smaller homes in urban areas, that are likely to have a combi-boiler, and where the shell of the building is not energy-efficient enough to rely on electricity alone. But as the efficiency of the building is improved and upgraded over time, the hybrid system’s operating mode can be shifted to more electric heat pump share. And while there’s a lot of talk about new homes in the renewable heating debate, hybrid technology is ideal for renovations and boiler replacements. Heating system replacements We estimate that there are 1.1 million homes across the country that would be well-served by a hybrid system. That, combined with the benefits of hybrids for both installers and consumers, is why we firmly believe in hybrid heat pumps’ potential to support a faster, easier, and more affordable transition to low carbon heating in this country. Every homeowner who buys a Daikin Altherma hybrid system gets a high-efficiency boiler for free When consumers are looking at heating system replacements, we know that complexity and disruption are barriers to purchase. Fortunately, neither is an issue with hybrids. While hybrid heat pump systems can be installed with a household’s existing boiler, to help increase uptake, we’re running a special offer at the moment whereby every homeowner who buys a Daikin Altherma hybrid system gets a brand-new, high-efficiency boiler for free. Low carbon technology And there’s no need to lose valuable floor space to a hot water cylinder or to make changes to the radiators. Hybrids aren’t just good news for homeowners; they represent a real opportunity for installers, too. At the moment, there are 1,000 heat pump installers in the UK and around 125,000 gas boiler installers. We need to transition these boiler installers towards low carbon technology – not just to drive progress on the road to net zero, but to help their businesses stay relevant and competitive. This year, in partnership with 11 of our Daikin Sustainable Home Centres across the UK, we’re running a free nationwide training program to help installers enter the renewable heating market with hybrid heat pumps. eco-Friendly hybrid solution Reducing electricity prices isn’t enough to encourage people to change the way they heat their homes Installers who complete the day-long course can expand their portfolio and gain the skills to upgrade customers to an eco-friendly hybrid solution. Reducing electricity prices isn’t enough to encourage people to change the way they heat their homes; more needs to be done to make new, clean technologies accessible and appealing. We’re doing what we can to incentivize homeowners – and installers – to embrace the possibilities of a hybrid heat pump system, but a clear funding mechanism from Government is needed as well, specifically to help with the upfront cost of upgrading (free boiler or no free boiler). While the now-closed Green Homes Grant explicitly included hybrid heat pump technology, there’s a big question as to whether the same hybrid solutions will be included in the Clean Heat Grant – the details of which are expected later this year. The answer to that question needs to be ‘yes’.
‘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.
When COVID-19 hit, North Arkansas College had to close its school, and students had to transition from in-person to online learning, which is especially difficult when teaching a trade that is heavily dependent on hands-on training. The HVAC/R program at North Arkansas College, which has existed for over 50 years, typically has an average of 14 to 16 students enrolled each year. HVAC/R program “With the quick transition we had to think outside the box, and so we found a company that had created a software for the HVAC/R Industry to help contractors and service companies give their service technicians additional training in areas that they needed,” said Jeff Smith, a licensed HVAC/R contractor who teaches courses at North Arkansas College. The software uses virtual reality (VR), a computer-generated simulation that enables a student to interact with an environment using electronic devices. The software chosen by North Arkansas State could be used for desktop (two dimensional) or with VR equipment (headset). Software using virtual reality (VR) The original thought was to send a laptop and VR headset home with each student, during the COVID-19 pandemic, to potentially get the hands-on training that they were missing, but that plan did not work out due to the overall costs and possible technical difficulties. “However, we recognized the value in the VR system and knew right away it would make a great tool to help build on what the students were already learning in the classroom and lab settings,” said Jeff Smith. SkillMill software The college uses Interplay Learning Software’s SkillMill, which was designed specifically for the HVAC/R industry The college uses Interplay Learning Software’s SkillMill, which was designed specifically for the HVAC/R industry and other trades. The software was also developed to work with several VR headsets brands, including the Oculus Rift S used at North Arkansas College. Jeff Smith said, “We believe the VR systems have been successful because we have witnessed improved lab skills, and we have heard our students discussing the tasks that they accomplished while using the VR systems and how those tasks helped them in their lab studies and in their HVAC/R internships.” Positive feedback on VR systems He adds, “All our students have given great feedback on how the VR systems have supplemented their learning, training experiences and how it could provide them with an additional edge to successfully enter the HVAC/R industry.” When they were developing the VR Lab, North Arkansas College had not heard of any other colleges using this technology specifically for HVAC/R training. Since then, they have had schools ask questions such as: How much does it cost? How did they integrate it with the curriculum? And is there a learning curve? The advantages of applying VR technologies in the HVAC discipline are numerous Applying VR technologies in HVAC The advantages of applying VR technologies in the HVAC discipline are numerous. Safety is always a major concern when students are working on live electrical circuits and pressurized systems. Using the completely safe VR environment, instructors do not have to worry about students becoming injured, while learning to troubleshoot and service HVAC/R equipment. Another advantage is that a student cannot accidentally break a part or component while learning to work on HVAC systems, which helps with costs. Also, students have the opportunity with the VR system to troubleshoot systems that may not be available in the lab, such as large chillers and cooling towers. Students embrace VR approach Today’s students have such a strong connection with technologies that are associated with VR systems" Today's students are more likely to embrace the VR approach because of their affinity for video games, for example. And there are other factors related to youth culture/technology that make the approach desirable. “Today’s students have such a strong connection with technologies that are associated with VR systems,” said Jeff Smith, adding “Just about every student is tech savvy. The majority of them have a natural inclination toward technology because of our smartphones, tablets, gaming systems, computers, etc. That makes VR training a perfect match for our younger generations.” Funds for additional VR systems Since the program began, North Arkansas State has had major contractors interested in what they are doing, how it works, and the added benefits for the students. However, HVAC/R contractors may not realize the benefits or the full potential of this new training product, until they see it for themselves. When they do, they are amazed at what they see, according to Jeff Smith. Another challenge is acquiring more funding for additional VR systems. “We would like to have a VR station for every student but for now we have a schedule to rotate the students through,” Jeff Smith concludes.
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.”
US$ 4.6 million in projected energy and operating cost savings empowered the Charleroi Area School District, a western Pennsylvania public school district to renew assets and improve indoor air quality for shared learning spaces. After their immediate responses to COVID-19, many schools reassessed ventilation assets and started vetting plans to ensure healthy indoor air going forward. To green light a fiscally responsible solution, Charleroi Area School District (CASD) needed a way to overcome humidity and boiler issues interrupting learning without adding excessive burdens on community resources. Needlepoint Bipolar Ionization technology ABM’s custom solution created a projected US$ 4.6 million in energy and operating cost savings ABM’s custom solution created a projected US$ 4.6 million in energy and operating cost savings. In addition to improved lighting, HVAC and building controls, the project added Needlepoint Bipolar Ionization technology, a pathogen and particle control measure for ventilation systems, to every facility. Prioritizing healthy air and fiscal responsibility together after assessing CASD assets, operations, and goals, ABM technical experts were able to identify opportunities to improve facilities for students and teachers, while reducing energy and operating costs. By creating that savings, the project empowered CASD leadership to protect air quality and community resources going forward. “Together we have been able to solve HVAC issues that have interrupted the learning process in the past,” said Dr. Ed Zelich, Superintendent of Charleroi Area School District, adding “Consequently, we’ve been able to obtain sustainable, efficient air quality improvements that are safeguarding our learning environments for the future.” Energy Performance Contracting Program ABM’s Energy Performance Contracting Program enables investment in indoor air quality (IAQ) for shared learning environments and community sustainability goals by driving costs out of operating budgets and redirecting savings to critical needs. Facility upgrades included energy conservation measures for seven facilities across the district, including Charleroi Elementary Center, Charleroi High School, and the Sports Complex. Highlights of the project include: Replacing aging boilers and ventilation equipment Re-commissioning and optimizing HVAC systems Building automation system upgrades, including new sensors for monitoring IAQ Needlepoint Bi-Polar Ionization installations Installing water conservation upgrades Replacing high-efficiency transformers in electrical power distribution systems LED lighting upgrades Roofing and building envelope improvements
