Plans to decarbonize Britain’s homes will fail without a rise in heat pump installers, with warnings from the Environmental Audit Committee confirming that the supply chain needs to be strengthened. To see 600,000 heat pumps installed by 2028 in line with the Prime Minister’s Ten Point Plan, one need to see a rapid rise in the number of installers qualified to install the technology. There are over 22 training centers across the HPA membership alone, providing the ability to train over 7000 installers per year. However, an overhaul of the training pathway to becoming a heat pump installer has been needed for some time. Technology-Neutral course The Heat Pump Association has been working hard with key actors across the heating industry to simplify the training pathway for heat pumps and level the playing field between technology types. Led by CIPHE, the first part of this new pathway has developed into a new low temperature and hot water course that they believe will help to address the low carbon skills gap and turn the Governments aspirations for heat pumps into a reality. The course officially launches in May 2021. Low temperature and hot water course therefore begins with a technology-neutral course It is important that installers have the skills they need to install all heating systems to perform more efficiently. Low temperature and hot water course therefore begins with a technology-neutral course, covering essential skills for efficient heating that apply to all heating types. This includes heat loss calculations, hydraulic balancing, pipe and emitter sizing and low flow temperature heating. This two-day course has been positioned as a prerequisite for any technology-specific courses taken later on. Low carbon technologies Once an installer has completed the initial technology-neutral course detailed above, they will have the option to take up training in specific technologies. The HPA has also proposed a Low Carbon Skills Card to allow them to keep track of all courses undertaken and demonstrate their credentials to households. Customers will then benefit from the knowledge and peace of mind that their installer is trained and accredited to install low carbon technologies like heat pumps in line with plans to roll out low carbon heating in homes across Britain. The heat pump training pathway that exists today is outdated. Their proposed route, has been designed to simplify the training route and make it more accessible. The installer will first get to grips with the knowledge they need to install a heat pump, and then delve into each technology type. Heat Pump Foundation Course (2 days) Overview of heat pumps Installation guidelines Commissioning/Servicing End user training Individual Heat Pump Technology Course (1 day per technology) Air Source Course (1 day) Ground Source Course (1 day) Exhaust Air Course (1 day) Heat pump installer The course content must be updated to reflect any changes as and when needed to ensure that installers derive the most benefit from their training. This will be crucial as the market continues to innovate as growth occurs. The Climate Change Committee has advised the Government that buildings must be addressed in order to meet the 2050 net zero target. The course content must be updated to reflect any changes as and when needed With 37% of emissions arising from heating, the phase-out of fossil fuel heating is both essential and inevitable. It is therefore essential that the Government supports initiatives to train installers so that they can install the technologies that will be rolled out as an alternative. Installers need to see clear and unequivocal support for heat pumps from the Government through both stable long-term policies and financial support. Government support is particularly important when they consider that the costs associated with becoming a heat pump installer currently outweigh those needed to become a gas boiler installer. Gas safe register This clearly contradicts UK climate targets and is a challenge that must be overcome. The Government could help level the playing field between heating technologies through the introduction of regulatory measures that require all heating installers to undertake the newly launched low temperature and hot watercourse. These skills are not only needed for heat pumps and will help installers to adapt to the changing market as soon as possible. Every five years, installers are required to undertake Accreditation Certification Scheme (ACS) refresher modules to ensure they are on the gas safe register and working safely and legally. There is an opportunity for the low-temperature heating and hot water-dwelling module to be added to this established ACS re-accreditation framework and to provide a significant proportion of the market with the skills they need for the heating transition within the next five years.

With indoor air quality more essential than ever with the infectious COVID-19 still active worldwide, eradicating the virus while it's airborne is crucial to mitigating its transmission. Energy Cloud, a clean-tech company specializing in healthy buildings and energy-efficient environments has a solution: Hummingbird™ EQ, an air purification system that captures and deactivates airborne COVID-19 virus. Air Vaccine™ technology Hummingbird™'s EQ with Air Vaccine™ technology was independently tested by a distinguished team of epidemiologists and professional engineers assembled by Black & Veatch, global infrastructure pioneers vastly experienced in pathogen-tracking methods and construction of biological safety-related sites. Funding was provided in partnership with Black & Veatch's IgniteX COVID-19 Response Accelerator. BSL-3 tested Hummingbird™ EQ's deactivation of the virus – known scientifically as SARS-CoV-2 – was independently tested and proven, with all Biosafety Level 3 (BSL-3) work performed within The Hastings Foundation and Wright Foundation laboratories at the University of Southern California (USC). SARS-CoV-2 BSL-3 resources were supported by a grant from the W.K. Keck Foundation's COVID-19 research fund. "Supporting Energy Cloud aligns with our strategic priorities in building a world of difference," said Lance Lippencott, program director at Black & Veatch. "Having witnessed the global impact of COVID-19, we were eager to marshal our resources behind innovations such as Hummingbird™, which offers an opportunity to mitigate the pathogen's spread." EQ Testing Hummingbird™ EQ was proven to capture and deactivate the COVID-19 virus on the first airflow pass by 99.5% Hummingbird™ EQ was proven to capture and deactivate the airborne COVID-19 virus on the first airflow pass through the system by 99.5% or greater, reducing it to undetectable levels. In the most comprehensive bio-aerosol study of its kind, Hummingbird™ EQ was tested by simulating a real-life airflow scenario, complete with the ducting, coil, and an air handler / forced air unit. Testing included infectious aerosolized virus samples with simulated saliva that were more than 3,000 times the average infectious dose to prove hummingbird™ can thoroughly neutralize and remove any active COVID-19 virus from the air that passes through the system. The goal set out by the Energy Cloud COVID-19 response team was to test a scenario far greater than a normal real-life situation. Efficiency and analysis "My main goal with Hummingbird™ is to save lives, and to do this, we needed to independently test the system with real-life air flows to prove the efficacy through science and data.” “I am grateful for the opportunity to test Hummingbird™ at such a prestigious institution as the University of Southern California and their BSL Level 3 lab, and for the positive independent peer-reviewed analysis from our COVID-19 response team of epidemiologists and professional engineers assembled by Black & Veatch," said John Carrieri, CEO of Energy Cloud. Suitable for every environment Hummingbird™ EQ can be installed and scaled to any size heating, HVAC system or used as a stand-alone unit Testing also was performed with all Hummingbird™ models, confirming that they all deactivate COVID-19 with no harmful ozone being produced. Unlike other air purification systems, Hummingbird™ does not release or produce any airborne chemicals as part of its inactivation of viruses. Hummingbird™ EQ can be installed and scaled to any size heating, ventilation and air conditioning (HVAC) system or used as a stand-alone unit in all types of commercial and residential settings including hospitals, schools, supermarkets, hotels, airports, offices, homes, and more, for superior air quality in any sized indoor environment. Features Hummingbird™ EQ is unique beyond its virus efficacy as it includes: Air purification technology that decomposes VOCs and reduces bacteria, microbes, pollen, dust, dander, allergens, spores, fungi, mold, odors, smoke, and toxic fumes without producing any harmful ozone or biproducts.

The last 18 months have seen an acceleration in digitalization across many aspects of work and home life. Home spaces have become workspaces, and commercial buildings have had to adapt to changed use and lower occupancy rates. Coupled with this, there is a growing need to dramatically reduce carbon emissions from buildings - according to the International Energy Agency (IEA), the buildings and construction sectors combined are responsible for over 30 percent of global energy consumption, and nearly 40 percent of carbon emissions. Installing separate systems This means that demand for a smarter approach to heating, ventilation and air conditioning (HVAC) management is crucial for building managers, who need to ensure that their properties can adapt to changed use, respond to the wellbeing of their occupants, and run efficiently to keep emissions as low as possible. Armed with this data, facility managers can take proactive steps to improve usage Of course, architects and developers have been installing separate systems to control HVAC for decades which have given building managers greater control and access to different areas of a site. However, with digitalization comes the addition of web-based platforms to allow these verticals to integrate seamlessly with each other, providing data on how efficiently and effectively a building operates through a single view application. Armed with this data, facility managers can take proactive steps to improve usage, which will see properties proactively react to the environmental and personal needs of their occupants. Centrally controlled lighting Many commercial buildings will already have a certain element of smart technology installed – from centrally controlled lighting and HVAC systems to remote management of security and energy management systems. However, it is often the case that these multiple applications are managed in silo. This means facilities managers don’t have a consolidated view of their data. In addition, not all managers will be using the data these devices produce to take steps to reduce the carbon footprint of their properties. Embracing smart technology – and a central control platform - gives building managers access to instant data on how their HVAC assets are performing in one place. This insight can be used to gain a thorough understanding of how the different systems in the building interact, and the external factors that may impact them. Effective building controls By using this data, operators can implement effective building controls to manage efficiencies By using this data, operators can implement effective building controls to manage efficiencies, identify maintenance issues, ensure the wellbeing of occupants, and inform future investment priorities. So, for example, if a building is now being used in a different way due to changed occupancy, the data will show the manager what needs to be done to ensure it is operating as efficiently as possible. We know that there will be increased demand for more flexible spaces as companies move towards remote or hybrid working models. It is likely that we will visit our offices less for day-to-day work and use them more as hubs to meet and collaborate. The ability to turn a traditional ‘bricks and mortar’ building into an agile asset that can learn and adapt to its surroundings will become increasingly important. Smart HVAC management Smart offices will become independently intelligent, learning how occupants use the space and services, adjusting lighting, HVAC and other systems to maximize health and comfort. Smart HVAC management will create a trend for ‘healthier’ buildings that will have a positive impact in terms of improved quality of life and wellbeing of occupants, ultimately resulting in higher productivity levels. In short, there has never been a better time to adopt smart HVAC technologies. Intelligent buildings that would have been unimaginable a few decades ago are now a reality. As buildings become smarter, they can learn how occupants use the space and services and proactively adjust lighting, HVAC and other systems to improve use, cut emissions and reduce energy consumption.

As our urban centers grow, so does our demand for key resources, such as energy. Currently, cities are accountable for over 60% of resource use and an estimated 70% of global carbon emissions. In the Middle East particularly, countries have experienced unprecedented population growth, increased economic activity and consequently, increases in energy consumption. Integration of sustainable systems Fortunately, industry leaders and governments are placing sustainability at the heart of regional plans for urban development. The integration of sustainable systems is no longer a value-added benefit, but rather a necessary requirement. I believe a vital element for sustainable development in our cities is energy management. Energy is a costly commodity representing an average of 25% of all operating costs in office buildings. This cost, however, can be reduced by using energy management to optimize HVAC systems employed in a building. Effective energy management Energy management involves proactive tracking, systemic management and thoughtful optimization of energy consumption in a building, with the goal of improving energy efficiency. The concept of energy efficiency takes into account a variety of factors; we must consider system design, quality of installation and maintenance, efficiency rates and personal use. If we assume a system is designed with greatest efficiency in mind, its effectiveness is still deeply impacted by installation, maintenance and use. ‘Performance drift’ issues One challenge we face with the efficiency of HVAC systems is ‘performance drift’ One challenge we face with the efficiency of HVAC systems is ‘performance drift’. When first installed, and even in the first few months, HVAC systems operate immaculately. Over time, however, component efficiency and system conditions ‘drift’ away from the originally installed operating curve, meaning that efficiency and performance of the system can degrade incrementally. The deteriorating performance of HVAC systems has consequences, such as unnecessary use of energy, resulting in higher costs and emissions, in addition to reduced comfort for building occupants. Energy efficient HVAC pumps In order to truly have an impact on energy consumption, a holistic approach must be adopted. Only by carefully examining and optimizing each part of the HVAC system, can we then find ways to improve it. In my experience with Armstrong Fluid Technology, in the last decade, the technology for HVAC pumps has been enhanced to provide up to 70% energy efficiency savings through demand-based control and parallel pumping technology. These innovations enable the pumps to operate at optimum levels, consuming as little energy as possible. Innovative smart technology Systems that incorporate innovative smart technology enable more accurate system performance analysis and optimization. Pumps can function as highly accurate flow meters that provide valuable insight for building managers and operators. Data from the intelligent connected pumps can be collected through active performance management software, which enables the HVAC system to learn, predict and optimize to deliver even greater energy efficiency and cost savings through maintained optimized performance. Systems incorporating innovative smart technology enable more accurate system performance analysis Active performance management software Active performance management software enables real time and historical data reporting that directly demonstrates system efficiency and savings. Given the global shift towards sustainable building construction, legislation on energy reporting is inevitable, therefore employing systems with this in-built capability can prove to be extremely beneficial in the future. The software can also help maintain client comfort at all times by enabling predictive maintenance. Systems can provide alerts when they detect faults, allowing for early replacement before a full breakdown. This can be particularly helpful in mission critical applications such as hospitals. Importance of analyzed data in system optimization Without the ability to analyze data, buildings managers and operators cannot properly optimize mechanical systems Evidently, collecting data is essential for many reasons, including preventing, and even reversing, the loss of energy efficiency. Without the ability to analyze data, buildings managers and operators cannot properly optimize mechanical systems, which results in unnecessary energy use, insufficient maintenance practices and any related costs. There may be hesitation in the industry to incorporate more sophisticated systems as they require initial investment, however, the returns from using more efficient mechanical systems are impressive. Executing energy upgrades for HVAC systems Simple payback on energy upgrade projects is usually reached within 3 to 5 years. Furthermore, energy savings continue for the life of the system. Properly executed energy upgrades deliver up to 40% savings on energy consumption related to HVAC operation. Savings on that level for a large facility can be impactful for business operations. Energy efficiency is not ‘visible’ but has the potential to have a transformative effect on climate change, if embraced on a large scale. If we consume energy only as we need to, then we consume less of it. This, in turn, reduces our consumption of fossil fuels and consequently our greenhouse gas emissions. Aside from short-term benefits, such as costs savings and increased operation efficiency, energy management has the ability to help conserve energy for generations to come. Embracing energy saving solutions If we embrace innovative energy saving solutions in the building services industry, then we can begin to make a difference. With the recent launch of plans for sustainable development, such as the Dubai Master Plan 2040, green infrastructure, supporting solutions, will thrive. The global shift towards embracing sustainability has made individuals and organizations call into question their impact on our planet. Embracing sustainability is no longer a preference but a strategic business approach that helps to create long-term value on a social, economic and environmental level. The role of energy efficiency, and the systems that enable it, will inevitably play a key role in creating more sustainable buildings, communities and cities.

Forget the fact that heat pump installations in the average home could cost several thousand pounds more than a conventional gas boiler and that fully insulating those homes will add even greater cost to the homeowner. It’s not really the cost issue that could be the only potential bump in the road on the way to the target set by the UK Government, because a more pressing problem to solve will be the shortage of trained ‘green’ heating engineers that will be the key to delivery of the plan. Gas boiler production I’m sure I’m not alone within the industry in adding my support to any drive that leads to a more effective use of environmentally responsible sources of energy for home heating. And following the news that ministers are currently discussing a cut off date of 2035 for all domestic gas boiler production, with an earlier 2025 ban on their installation in new homes, it is encouraging to think that technologies with which we in the industry have been working for a decade or more, will finally become the norm, rather than the green exception. However supportive I and colleagues in the sector might be, we should not shy away from challenging the Government on the delivery of the targets it has announced, because currently we haven’t heard enough in the Government’s Heating and Buildings Strategy about the market’s skills shortage. Heat source technologies At Ameon we’ve been working with green technologies for over a decade, on large scale public sector The truth is that there are simply not enough heating engineers currently who are experienced in the installation of alternative heat source technologies, such as ground or air source heat pumps, and given that tens of thousands of new or re-skilled engineers will be required if the Government’s plan to install 600,000 heat pumps per year by 2028 is to be achieved, then the drive needs to be supported by the associated training provisions to help it meet its goal. At Ameon we’ve been working with green technologies for over a decade, on large scale public sector and residential developments but I feel that aside from building services infrastructure companies like ourselves and others in our sector, there isn’t currently a large enough skills base and therefore the infrastructure needs to be put in place to be able to train enough people to carry out the installation program. Low carbon technologies This could be more of a factor in the achievement of 2035 target aspirations, than even the potential public reluctance to embrace the technology for cost reasons. Whilst specialists in our sector have teams of qualified heating and ventilation engineers who are hugely experienced in low carbon technologies, it has to be acknowledged that their experience and skill set has taken considerable time and investment to develop; therefore I hope the Government hasn’t underestimated the vital importance of training. This could be more of a factor in the achievement of 2035 target aspirations You can’t simply ask domestic heating engineers, who are used to fitting conventional gas boilers, to switch to installing ground or air source heat pumps overnight. There are significant differences in the science and the technology, together with the requirement by law for engineers to be F-gas registered, proving that they are qualified in the safe handling of fluorinated refrigerant gases (F-gas), which are ozone depleting substances crucial to the heat pump delivery process. Conventional gas boilers Then, there’s the need for engineers to understand how to design low temperature water systems and avoid such things as Legionella bacteria creeping into the system. There is much more to learn for someone used to installing boilers that heat water to a temperature to pasteurize it, because the public health element is a key factor too. So there needs to be significant retraining and, of course, the time to create the infrastructure to deliver the training. The other related issues, such as where training would be delivered and who funds it can be more easily addressed. After all, the Chancellor has protected UK businesses at the drop of a hat in the midst of a pandemic, and the country has, in short time, created a hugely efficient mass-vaccination program; proving that anything is possible. Reducing carbon emissions Steve Baker, has warned of public anger if all implications of the Government’s plans are not explained Currently discussions in Whitehall include such ideas as homeowners being required to install ‘green’ heating before they can sell their property, or levying a surcharge on gas boilers to subsidize production of heat pumps: although no firm decision has yet been taken. It is reported that former Conservative minister, Steve Baker, has warned of public anger if all implications of the Government’s plans are not explained fully to homeowners, which is why I and others will add our voices to the many questions that really need to be answered. That doesn’t mean we in industry are not fully supportive of the Government’s aspirations. The public too appears to be broadly behind this move to reduce carbon emissions, particularly as gas boilers account for a percentage of CO2 produced annually; therefore it is an important area to focus upon if ‘net zero’ carbon emissions by 2050 are to be achieved. Newly trained engineers Roughly 85% of UK homes currently rely on gas for heating, which is around 25 million homes, so the scale of the change required is immense. Even if the UK had the qualified engineers to start from day one, which it doesn’t, the targets are ambitious to say the least. It is my view that investment in training has to be at the heart of the Government’s planning. That could be delivered on the job, in the classroom, or, as has become the norm during lockdown, via online platforms such as Teams, Zoom or Skype. So if the will is there and the resources are in place to fund training, the method is the easier part of the process. What’s less certain is whether the army of re-skilled and newly trained engineers can be deployed quickly enough to achieve the target set. The clock is ticking...

Interfacing with HVAC products is increasingly complex. The tiny 1-inch LCD display included on systems does not lend itself to complicated functions. Keeping the HVAC user interface simple limits control options to on/off, mode change or choosing a temperature. Thermostat controls company COTHERM has developed a smartphone app that can be used to control complex functions such as product settings during installation, programming or providing technical information about an HVAC product. Near field communication (NFC) relays information from the smartphone app to the HVAC equipment. Conventional HVAC equipment “NFC technology can be leveraged by heating, ventilation and air conditioning (HVAC) manufacturers so that installers can adjust the settings for radiators, as well as water or space heaters, via a mobile phone,” says Alain Maillard, Marketing Director of COTHERM. NFC is a contactless technology that enables transfer of short messages between a smartphone and an object. The technology is widely used and is already popular for uses such as contactless payment The technology is widely used and is already popular for uses such as contactless payment, access control and transportation. The large color screen display of a smartphone and the familiarity of app usage provides a strong tool for user interface and is much more user-friendly than conventional LED or LCD displays with keypads that commonly equip conventional HVAC equipment. This is particularly evident for advanced settings that need a lot of menu navigation like programming. Using NFC technology NFC provides a remote user interface using a smartphone to facilitate the configuration or setting of the product. In effect, the smartphone becomes the user interface of the product, and there is no need to use a complex display with a keyboard. The approach also does not require complex IT installation or pairing as would be required with other technologies like Bluetooth or Wifi. Because communication is based on proximity, data exchange is safe, and you do not need a password or login to connect. The Electric Radiator is COTHERM’s first equipment to use NFC technology, and the first market introduction is in France. The first company to introduce the technology is ‘Univ’R Chauffage’ for the 2021 winter season. For an installer, simplicity is key. Permanent communication link The actual appliance is simplified to include only the most commonly used functions The NFC approach provides time savings for installation as it does not require a login/password of a local network. And it is error free: An app can have a pre-defined setting package that is impossible using a native LCD+ keyboard on traditional equipment. For the user, the actual appliance is simplified to include only the most commonly used functions. There is no pairing or setting, ensuring simplicity. And the system is hacker-free as it requires a proximity exchange and works without the cloud. Data exchange is only activated while the smartphone is close to the radiator; there is no need for a permanent communication link. As a consequence, there are no waves pollution and no energy consumption that may be due to maintaining permanent communication. For appliance manufacturers, the cost-effective solution is innovative and easy to use. Limited support is needed as there is no installation (except downloading an app from the store). Industrial HVAC products The approach also enables a contactless customization of the appliance at the end of the production line in the factory with no power supply on the appliance because NFC is energy harvesting. The approach can be used for industrial HVAC products as well as residential appliances. NFC provides cost advantages, eliminating the need for a high-end display on an appliance. Some sensitive technical data or setting may be reserved for a technician only Information is also addressable: A filter can be set with data from the appliance accessible by profile. Some sensitive technical data or setting may be reserved for a technician only or for use at the factory. In the HVAC application as implemented, the controller of the appliance is used as the NFC tag and the smartphone is used as a reader/writer terminal with color display. The controller of the appliance includes an NFC antenna and a small, dedicated NFC controller with memory. Providing additional benefits On the other hand, the smartphone can be iOS or Android and needs to have the COTHERM NFC App downloaded. NFC is available on iPhone from iPhone 7 and on Android; all smartphones with NFC are compatible. NFC technology provides additional benefits, too, including: Traceability and storage of historical data. Easy setting of Wi-Fi or Bluetooth configuration when combined with NFC. Preset of the appliances or any equipment at the factory, including enabling or disabling. Functions or changing settings to enable customization based on distribution channel for brand. Directly points to the correct app on the store for download when using the smartphone for the first time. Self-launch of the app when the smartphone is close to the NFC tag. Further expansion is planned in Europe. The combination of the technology has received an innovation reward as a European funding project Touch & Heat by DIGIFED Europe program (Horizon H2020). Partners in the DIGIFED program are IoTize, a French startup, and Lucht LHZ, a German manufacturer of Electric Radiator. Product introduction in other European countries is planned for 2022. HVAC equipment such as water heaters or heat pump water heater controllers are the next target for the technology.

The COVID-19 pandemic has changed the way the world lives, escalating the need to prioritize health and safety where we live, work, learn and play. As organizations around the world respond to the pandemic, the International WELL Building Institute (IWBI) has leveraged its expertise to help. Impact of building surroundings IWBI is a public benefit corporation focused on deploying “people-first places” to advance a global culture of health. The community has adopted the WELL Building Standard, which is the anchor in an ecosystem of certifications and ratings focused on creating and benchmarking health and well-being in built environments. IWBI understands that companies have realized the importance of feeling safe inside and the importance of mental health — and how building surroundings impact that. WELL Building Standard (WELL) IWBI is focused on the ways that buildings, and organizations, can improve comfort and enhance health and well-being IWBI is focused on the ways that buildings, communities, and organizations, and everything in them, can improve comfort, drive better choices and generally enhance health and well-being. The work is global, covering 2.5 billion square feet of real estate in nearly 100 countries as of June 2021. The WELL Building Standard (WELL) is a vehicle for buildings and organizations to deliver more thoughtful and intentional places that enhance human health and well-being, according to IWBI. It’s the standard for buildings, interior places, and communities seeking to implement, validate and measure features that support and advance human health and well-being, leading to official certification. Measures to become WELL Certified A building becomes WELL Certified (WELL Building) following the adoption of features from the WELL Building Standard, achieving a threshold based on measures that are validated by a third party.  These measures include building performance and their impact on people’s health and well-being. HVAC is a key element of WELL buildings. The primary purpose of HVAC systems is usually to improve the environmental conditions for the building users. Introducing outdoor air combats the buildup of carbon dioxide and volatile organic compounds, which at high levels can lead to sick building syndrome. Particle filters can remove much of the pollution from traffic or forest fires before it is introduced indoors. Problems with HVAC But HVAC systems can create their own problems. For example, cooling coils and drain pans can become a habitat for mold growth if not properly maintained. The WELL Building Standard addresses issues related to air quality and HVAC systems with a holistic approach, with adaptable strategies covering air, thermal comfort, and material. WELL Certification The WELL Building Standard includes strategies in 10 WELL Concept areas, from HVAC systems to architectural details  The WELL Building Standard is a global framework for creating and certifying places that advance health and well-being. It includes strategies in 10 WELL Concept areas, covering topics ranging from HVAC systems to architectural details to human resource programs. WELL Certification is granted following a third-party review that these requirements have been met in a process that involves both submissions of documentation and on-site testing and inspection. Organizations can also enroll groups of projects in the WELL Portfolio, enabling them to document and celebrate their incremental progress in WELL feature achievement and employ the strategies at scale. Professional engagement Stakeholder engagement, including engagement by professionals in the HVAC space, has always been a key part of the development of WELL. For example, there was a 6-month public comment period to solicit feedback on the WELL v2 pilot before its graduation in 2020. Also, just before completing WELL v2, a Task Force on COVID-19 and Other Respiratory Diseases sought to identify any additions that could be added in light of the pandemic. There is also a network of more than 230 experts who participate in 14 IWBI advisories. Within this, there is an advisory for each of the 10 WELL Concepts, including 35 advisors in the Air and Thermal Comfort advisories. Challenges The most important challenge IWBI faces is the same one facing all others: Recovery from the COVID-19 pandemic and the ticking clock of climate change — and all that goes along with it. “As we continue to combat COVID-19, we recognize that feeling comfortable and safe inside is more important than ever,” says Nathan Stodola, Chief Engineer at the International WELL Building Institute (IWBI). “The pandemic has taught us the importance of air quality in preventing the spread of disease. This is a critical moment to keep the public informed on the latest scientific findings and best practices.” Adding a human element to buildings IWBI is working toward a future where buildings are designed with people — the human element — in mind" “We have also learned the value and importance of mental health, and how much employees want their employers to know that,” Stodola adds. “And IWBI is working toward a future where buildings are designed with people — the human element — in mind. There is an interconnectedness to all of this, and that’s how IWBI is working to serve the needs of the public.” WELL Health-Safety Rating In response to a rising need in the wake of COVID-19, IWBI introduced the WELL Health-Safety Rating for Facility Operations and Management in June 2020, a third-party validated tool designed to build confidence in the safety of a building. The WELL Health-Safety Rating provides an efficient and effective opportunity to guide, validate, recognize and scale the efforts of owners and operators on critical health and safety issues. Strategies undertaken Specific to the HVAC arena, many strategies that have come to light in the pandemic have been part of WELL since its inception, including sufficient ventilation rates, operable windows, awareness of mental health needs, and proper ergonomic design of workstations. But the Task Force on COVID-19 and Other Respiratory Infections also identified changes that have been implemented in the program, such as treating or eliminating recirculated ventilation air or allowing virtual training courses rather than requiring in-person classes. Most strategies in WELL are “evergreen:” They will continue to have benefits to building users even after the risk of COVID-19 diminishes, says IWBI.  Programs and resources IWBI offers several education programs and resources, as well as professional credential courses, for people in the architecture, engineering, construction, and design industries--and beyond. IWBI offers a training program for schools to educate people on how to maintain a healthy and safe school environment The WELL Accredited Professional (AP) program is designed for those looking to gain skills to help inform WELL projects to further advance human health and well-being in buildings and communities IWBI also offers a training program for schools to educate people on how to maintain a healthy and safe school environment. Focus on health and well-being WELL buildings are not just about design and construction, but also about how to operate space and create policies that change people’s behavior for advanced health and well-being, says IWBI. For instance, the Nourishment Concept is about providing access to healthy food, and biophilia features can help improve people’s mental health. Caters to all markets and budgets Additionally, people tend to think that WELL buildings are expensive or only for the luxury market. WELL applies to all types of places and can be implemented with various budget sizes based on individual projects’ health and well-being needs. Air and Thermal Comfort concepts The HVAC requirements in WELL are dependent on the facilities team in addition to the design team. People need buildings to provide places to live and work, and buildings need people to care for their systems. There are several features in the Air and Thermal Comfort concepts related to the ongoing measurement of conditions within the space and maintenance of the ventilation system.

It’s shaping up to be a long, hot summer for HVAC contractors and their customers. Disruptions in the nationwide supply chain that began during the COVID-19 pandemic still have not been resolved. Shutdowns last summer played havoc with the supply of parts, and suppliers are still playing catch up, as raw materials remain scarce. Furthermore, prices are going up among some components and key raw materials. Waiting times for parts can run into weeks or even months. Supply shortages of HVAC equipment Summer weather increases the demand for HVAC equipment, especially in hotter climates. A spike in air conditioner demand is generally welcomed by most contractors, but supply shortages make it difficult to deliver on customer needs. Managing a backlog of impatient customers is a new challenge for many HVAC companies. The shortages impact materials, such as steel, aluminum, copper and plastics, whose costs are expected to rise in coming months. Among metals, the price hikes could be 20 to 30%, while prices of plastics could almost triple. Copper futures recently reached an all-time high, and steel price indexes are also at record levels. Shortages of electrical components Shortages have been reported of copper and electrical components, such as motors and compressors Shortages have been reported of copper and electrical components, such as motors and compressors, which are specific to the units that use them. There is also a shortage of microchips that are components in high-efficiency systems and furnaces, and resins used in the evaporator coil pans are scarce. Some HVAC supply firms have had difficulty obtaining evaporator coils used in air conditioners. Specialty items such as control boards have a wait time of up to two to three weeks, or longer. Shortages projected till end of 2021 The shortages are projected to continue until the end of 2021. Even as small shipments trickle in, they are often sold quickly. The situation is unfamiliar to the HVAC trade, which has traditionally not had issues with equipment availability. Shortages in the HVAC market are a reflection of broader supply and cost challenges of the construction market. Prices for goods used in residential construction have increased almost 10% over the past 12 months, according to the U.S. Bureau of Labor Statistics. Higher transportation costs impact supply chain Higher transportation costs are impacting both the supply chain and HVAC contractors. Personnel shortages continue to plague many HVAC companies, too, and a technician shortage is also contributing to longer wait times in some areas. A scarcity of labor has been a 20-year challenge for the HVAC industry, but it is reaching new levels as days go by. Order in advance and stockpiling equipment Alternatively, HVAC contractors may seek to switch brands to help ease availability issues One approach contractors are taking to the problem is to order equipment in advance and stockpile it for when they need it. One Denver contractor reportedly ordered almost a million dollars of equipment in advance. Alternatively, HVAC contractors may seek to switch brands to help ease availability issues. Identifying a manufacturer that has stock available can ease the inconvenience of customers having to wait for new equipment. need for regular HVAC maintenance Another approach is to educate homeowners about the importance of maintenance, such as changing filters, which can avoid a need for larger repairs involving equipment that is in short supply. Maintenance service is doable because it doesn’t require new equipment, replacements or add-ons that can be hard to come by. Unfortunately, among consumers, maintenance may have been delayed or ignored during the pandemic, which is aggravating the urgency of the current situation.

Located in Worcester Massachusetts, Doherty Memorial High School is typical of many schools designed in the 1960’s. With two classroom wings joined together by hallways and anchored by an auditorium and gymnasium, the red brick school is home to approximately 1500 students. After 40 years, the school needed to replace the original hot water boilers and unit ventilators serving the upper and lower classroom wings. To design their new heating and ventilating system, the school enlisted the services of Shooshanian Engineering (SEi), Boston, Massachusetts. Outdoor air ventilation The original system design incorporated two gas fired hot water boilers sized to provide individual classroom unit ventilators with enough heating capacity to condition both the return and outdoor air loads. Rooftop exhaust fans pulled room air from each class-room to complete the ventilation process. ERVs recycle energy from building exhaust air to efficiently precondition outdoor air ventilation As recommended by the EPA and DOE, SEi evaluated the use of Energy Recovery Ventilation (ERV) as part of the new design. ERVs recycle energy from building exhaust air to efficiently precondition outdoor air ventilation, thereby reducing annual operating costs and boiler size requirements. After evaluating several ERV strategies, including fixed plate and run around loop, SEi determined that an ERV incorporating Airxchange rotary energy recovery wheels provided the best value. Estimates of installation and operating costs were evaluated for two designs: one with ERV and one without. As expected, the ERV based design provided the lowest operating cost. Capital equipment savings However, SEi was pleasantly surprised to discover the ERV based design, incorporating a smaller boiler and less expensive fan coil units, also provided the lowest installed cost. The capital equipment savings, made possible by incorporating Energy Recovery Ventilation in the design, more than offset the added cost of the ERV’s resulting in an instant payback. Installation included thirteen rooftop ERV units, each supplying from 1200 to 4600 cfm of ventilation air along with a single boiler to replace the two original boilers. Existing exhaust ducts provided exhaust air to the ERVs while new ductwork was added to deliver fresh outdoor air to each classroom. The design called for removal of the outdoor air intakes in the walls and installation of fan coil units in place of unit ventilators. Automated Logic software Performance of the new system is monitored using Automated Logic software Performance of the new system is monitored using Automated Logic software. The new system has received positive comments from teachers who expressed appreciation for the added fresh air and the ability of the classrooms to come up to temperature quickly at the beginning of the school day. “Even at the coldest temperatures the comfort of the supply air is amazing,” said Jeffrey Lassey, Director of Facilities with Worcester Public Schools. “You can feel the class-room come up to temperature much faster than with the old unit ventilators, and with the ERV system, we’ve reduced our energy costs considerably,” he added. Reduction in energy use over a 20 year period is expected to save approximately 3400 tons of CO2 emissions and $625,540 at current energy prices. Reducing energy consumption “Selecting the ERVs was a good shift away from unit ventilators, since it significantly reduces our energy consumption. This is particularly important because the cost of energy is heading nowhere but up.” - Jeffrey Lassey, Director of Facilities Worcester Public Schools. NSTAR, the local gas utility serving the city of Worcester, provides incentives for installation of energy efficient equipment through an energy rebate program funded by its commercial customer base. For the installation of an ERV based system and reduced boiler size, Doherty Memorial High School was awarded a $32,000 rebate from NSTAR. “Make sure to select Energy Recovery Ventilation from the outset in the design process in order to take full advantage of utility rebates slated for energy efficiency.” - Tom Angelo, NSTAR.
