As Statista research predicts the smart home sector will grow by 15.06% each year to a projected market volume of 9.249bn by 2025, a polymer specialist has upgraded its smart temperature control system to satisfy growing demand. To meet this demand amid the boom across residential, commercial, and mixed-use buildings, the latest upgrades to the NEA SMART 2.0 have been made to help contractors and developers deliver efficiency on each project. As building use and occupant habits change over time, the device also gives continued flexibility and adaptability to contractors and consultants to future-proof developments while the smart home market grows, as Franz Huelle, Head of Technical at REHAU Building Solutions, explains. Changing building requirements Franz says, “As we see offices and shops being converted into homes and flexible working spaces, the way we use buildings is changing more than ever, and with that so are occupant temperature requirements.” Futureproofing buildings in terms of efficiency and environmental credentials must be prioritized" “In the wake of sustainability and renewable energy targets and changes in legislation, futureproofing buildings in terms of efficiency and environmental credentials must be prioritized no matter the building type.” “With the latest upgrades to NEA SMART 2.0, we are looking to assist contractors and consultants with ensuring all buildings meet efficiency requirements no matter the use while satisfying the growing demand for smart controls long into the future.” NEA SMART 2.0 Regulates temperatures Suitable for new build and retrofitting for up to 60 rooms, the NEA SMART 2.0 uses an intelligent algorithm to regulate temperature and improve efficiency. Data learned from occupant habits, in addition to remote sensors installed indoors and outside for weather compensation, allows the system to reach the desired end-user temperature without excessive demand on the energy source. Optimizing efficiency To further help with efficiency demand, an optimized start feature has now been integrated. This begins to heat or cool ahead of the programmed time to reach the desired temperature in a controlled way to make sure the space is comfortable for occupants at the right time without excessive energy usage. A manual and automatic boost function is also available should the desired temperature need to be reached sooner. Reduced energy usage and cost savings The upgrades provide with an easy to install and flexible system that lowers energy costs in a variety of buildings" Franz added, “Energy efficiency and driving down running costs are key requirements of all end users, residential or commercial, and developments in government legislation are only going to increase this priority." "Consultants and contractors are now required to deliver buildings that facilitate this need for efficiency and sustainability long into the future.” “These upgrades will hopefully provide them with an easy to install and flexible system that lowers energy costs in a variety of building types. The smart home market is constantly growing, and we are optimistic that with these additional features, the NEA SMART 2.0 will continue to satisfy the growing demand for this technology long into the future.”

The latest round of financing from the UK Government’s Green Heat Network Fund (GHNF) will be key to ensuring that low-carbon district heating schemes are delivered from 2022, according to polymer pipework specialist, REHAU. Green Heat Network Fund (GHNF) The Green Heat Network Fund (GHNF) is the latest funding scheme, launched by the government’s Department for Business, Energy & Industrial Strategy, building upon 2018’s Heat Networks Investment Project (HNIP). As part of this latest funding tranche, the GHNF has pledged an additional £270 million investment in low-carbon technology, on top of the £165 million already provided by the HNIP. Steve Richmond, the Head of Marketing and Technical at REHAU Building Solutions, said “It is no secret that COVID-19 has impacted the decarbonization of the UK heating sector. The pandemic has left budgets strained for many, so investing in a new heating system simply hasn’t been a priority.” Low-carbon district heating schemes The heating sector currently accounts for as much as 21% of the nation’s emissions in total For this reason, schemes such as the Green Heat Network Fund will be key to putting low-carbon progress back on track post-pandemic. The heating sector currently accounts for as much as 21% of the nation’s emissions in total, so increasing uptake of heat pumps and district heating networks will be key to achieving net-zero by 2050. This development coincides with the launch of the CP1 Heat Networks Code of Practice, by The Chartered Institution of Building Services Engineers and The Association for Decentralised Energy. The publication advocates a maximum flow temperature of 70 °C for district heating networks, making them better suited to fourth-generation heating schemes. Polymer district heating networks Polymer district heating networks, using low-carbon technology, such as heat pumps and waste heat recovery systems, are one of the most effective ways to reduce reliance on traditional gas boilers. Low-carbon networks are the only form of network supported by the GHNF, so it is important contractors and consultants consider the recommendations in the CP1 guidance to deliver suitable installations. Steve Richmond concludes by stating, “The launch of schemes, such as the Green Heat Network Fund and regulations, such as CP1, will be critical to driving the uptake of low-carbon technology in England and Wales. Coupled with comprehensive training from specialists, such as REHAU, this demand will be a major factor in ensuring heat network installations is suitable for end users in a low-carbon future.”

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.

Over the last decades heating, ventilation, and air-conditioning systems became significantly more energy efficient. This is immensely important as they are one of the largest energy-consuming loads in commercial and residential buildings. Smooth performance of the systems requires careful installation, thorough cleaning, and regular maintenance. Running an HVAC system (energy) efficiently is challenging because of constantly changing variables: people entering and leaving a building, changing temperatures and seasons which affect the heating, cooling, and air quality immensely. Research by the European Commission found that buildings are responsible for 40% of all European energy consumption. Emission reduction goals This has a significant environmental impact and will become more expensive over the next centuries while countries work on their net-zero and emission reduction goals. How can the HVAC industry, in cooperation with the green tech sector, ensure less energy consumption and fewer CO2 emissions? Are any other energy-saving options available? Energy-focused digital twins can be used for the planning, operation, and optimization of systems Following, three data-driven solutions for more energy efficiency in buildings are presented. To understand and operate a technical system it is necessary to have a precise understanding of the system’s parameters and boundaries. HVAC systems are installed in buildings. Buildings, although varying in size, purpose, and layout, can be described by a set of parameters called a digital twin. Energy-focused digital twins can be used for the planning, operation, and optimization of systems. Machine learning algorithms In HVAC applications, a digital twin can be used to design and operate equipment more precisely. It helps to detect defects quicker or even before a failure appears. This saves maintenance costs and reduces potential downtimes. The biggest potential of energy-focused digital twins might be the possibility to use those data sets to train machine learning algorithms. This allows the use of artificial intelligence to optimize HVAC systems. It can raise the energy efficiency of these systems and significantly reduce costs and CO2 emissions. Machine learning offers the HVAC industry immense possibilities. Tracking energy usage on building and room level generates a valuable data set that can be used to operate HVAC systems more energy efficient. Tracking room utilization AI can also consider the exact number of people present in the building when regulating the temperature One example of the use of AI to achieve more energy efficiency is temperature control in buildings. No matter what time of day or night, nor outside temperature or season, the AI algorithm can optimize the temperature in the building according to those variables. AI can also consider the exact number of people present in the building when regulating the temperature. This is important as the number of people and their body heat change the room temperature significantly. The system reacts to all variables by heating more or cooling down further. While it is possible to count people while entering and leaving a building, it is also possible to track their room utilization. The algorithm can not only notice the changing temperatures in rooms caused by body heat. Overall energy consumption It is also able to track where the lights are turned on and off and at what times. Possible reoccurring patterns in those actions can be identified by the algorithm. All this information can be considered when adapting building and room temperature. Tracking people’s actions gives AI detailed information to incorporate into the optimization processes to achieve more energy efficiency. In the same manner, air quality and humidity can be optimized. Especially in commercial buildings, the ventilation is often running too high Especially in commercial buildings, the ventilation is often running too high. Over ventilation is a large waste of energy. If fewer people are in the building it should be lowered to reduce the overall energy consumption. Especially in a work environment, both temperature and ventilation are of high importance, as it has a direct impact on the productivity of most people. Smart control system A smart control system will process all available data on the energy usage in a building and adjust the HVAC system accordingly, in real-time. The more information it can gather for a longer period, the better the system becomes. This saves energy, emits less CO2 and reduces costs. A manual adjustment will never be as efficient, as the number of variables is too large. Additionally, AI can identify any irregularities occurring in the HVAC system and alert the responsible person. Predictive maintenance ensures less downtime. Voltage optimization based on a building’s energy consumption data is a solution that can also enhance energy efficiency in buildings. It can be applied to reduce costs, electrical energy consumption and CO2 emissions. Optimizing the voltage level in real-time means reducing it to a lower level, based on the consumption of the building. Highest savings level The CE certification shows that fluctuations of voltage can be tolerated by a device Electrical energy is supplied to buildings by grid operators. They are supposed to supply 230 V. However, a constant voltage level cannot be guaranteed. The voltage fluctuates. Therefore, all electronic devices must be able to work within those fluctuations. They allow a range of plus and minus 10%, which is compulsory by law. The CE certification shows that fluctuations of voltage can be tolerated by a device. 10% of 230 V allows the reduction of the voltage level to a minimum level of 207 V. At this level, all devices in buildings are guaranteed to run smoothly. Every volt above 207 V can thus be considered more than necessary for the devices to work properly. This means, that at the highest savings level, all devices still work within their specifications. Lower electricity costs But with a lower voltage, the energy consumption is lower. Consuming less energy results in a reduced carbon footprint and lower electricity costs. The advancement of technology and availability of higher resolution data already allows building managers to look at optimizing HVAC systems for better energy efficiency, especially in newer buildings where those systems are installed right away. Consuming less energy results in a reduced carbon footprint and lower electricity costs This provides less energy consumption and less CO2 emissions. As buildings and their HVAC systems are consuming large amounts of energy which emits tons of CO2 every year, enhancing the energy efficiency in buildings becomes crucial on the way to net-zero. Energy-Saving solutions HVAC systems must work with the highest energy efficiency possible, considering that the weather extremes we are experiencing all over the world (colder winters and hotter summers) will increase the demand for them, if not make them indispensable. But these solutions are not only available for new buildings. Existing buildings can also be retrofit by their owners and operators to take advantage of the emerging data-driven trends in the green tech industry. Energy-saving solutions like voltage optimization can significantly reduce buildings’ carbon footprints. Combing several different data-driven energy-saving solutions will reduce the carbon emissions in the building sector significantly.

‘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.

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
