Nidec Leroy-Somer (Nidec Leroy-Somer Holding), the world specialist with a wealth of experience in drive solutions for industrial refrigeration, has for more than 40 years provided refrigeration professionals with its state-of-the-art and energy efficient motors, and speed drives to effectively enhance productivity of industrial refrigeration applications. IE5 synchronous PM motors Nidec Leroy-Somer’s latest development, the Dyneo+ range of IE5 synchronous reluctance permanent magnet (PM) motors, with rare earth free rotor, offer multiple advantages for driving screw compressors, piston compressors, circulation pumps and condensers, be it in terms of energy efficiency, performance or reliability. Companies that use industrial refrigeration equipment have long been aware of the impact that the power consumption of a refrigeration installation can have on both the energy bills and on the environment as a whole. Energy-saving electric motors The cold compressor, at the heart of the system, remains the most energy-hungry element The cold compressor, at the heart of the system, remains the most energy-hungry element, and can represent up to 80% of total power consumption. Electric motors, which are ubiquitous in the cold chain, constitute the main source of potential energy savings. Thanks to its expertise in the design and manufacture of industrial drive systems, Nidec Leroy-Somer offers a wide range of drive solutions at fixed or variable speed, providing significant energy savings on the refrigeration market. Dyneo+ synchronous reluctance PM motor In addition to these complete and well-established ranges for this sector, Nidec Leroy-Somer has just launched its new Dyneo+ synchronous reluctance PM motor, ranging from 11 to 500 kW, for speeds of up to 4500 rpm. Specially designed for variable speed, this motor offers an economic and ecological solution for the requirements of industrial refrigeration. To address the energy transition challenges, the European Parliament recently voted, on 8 October 2020, in favor of a new ambitious climate law targeting 60% reduction of greenhouse gas emissions by 2030, and climate neutrality by 2040. European Commission Regulation (EU) 2019/1781 As part of this approach, the latest Commission Regulation (EU) 2019/1781, applicable to electric motors and variable speed drives, defines and schedules increasingly stringent efficiency levels for machines sold in the European market. Every industry  and in particular, the most energy-intensive ones are affected by these developments, designed to help protect the environment, not least considering that the cost of electricity is likely to climb significantly in the years to come. IE5 Ultra-Premium efficiency level With its IE5 Ultra-Premium efficiency level, Dyneo+ has all it takes to rise to this energy challenge With its IE5 Ultra-Premium efficiency level, Dyneo+ from Nidec Leroy-Somer has all it takes to rise to this energy challenge, offering as it does substantive energy savings in real conditions of use over the course of the cycle, at variable speed and load, as is typical with industrial refrigeration, where needs fluctuate considerably according to season and production level. Thanks to its energy performance, the Dyneo+ solution makes it possible to significantly increase the COP (‘Coefficient of Performance’, expressed by the ratio between refrigeration capacity produced and power consumption) of a refrigeration unit. As well as helping to reduce the carbon footprint, the range offers a TCO (Total Cost of Ownership) among the lowest on the market, and for rapid return on investment, generally in less than one year. Optimization of the number of compressors Dyneo+ motors are designed to operate exclusively with a variable frequency drive, allowing them to adapt to the speed of the machine being run and improve its performance when operating in over speed. This provides the benefit of additional refrigeration capacity for a given device, thereby avoiding having to start up another compressor during a production peak. Moreover, the Dyneo+ solution enables optimization of the number of compressors for a given installation. Delivering precise speed and torque control in sensorless mode, it guarantees constant torque over extensive speed ranges, with no derating or forced ventilation. Based on magnetic synchronous reluctance technology Nidec Leroy-Somer has developed the Dyneo+ range based on the mechanical platform of its IMfinity induction motors, known for their robustness and reliability. The use of proven components makes these new motors extremely robust and long-lived by design, thereby limiting the risk of refrigeration system failure. What is more, Dyneo+ has been designed for ease of installation, simple setup and easy maintenance. Generating low rotor losses, the magnetic synchronous reluctance technology reduces maintenance costs Generating low rotor losses, the magnetic synchronous reluctance technology reduces maintenance costs, in particular by extending the lubrication intervals. Whether compact or IEC interchangeable, with aluminum or cast-iron housing, or in IP55 or IP23 version, these motors are as easy to fit in new machines as they are to retrofit in existing installations as part of an energy optimization project. Connected to Systemiz interactive app Dyneo+ is connected to the Systemiz interactive application, which provides a wide variety of digital services, including instantaneous access to all the product literature, and easy and intuitive drive setup by simply scanning the QR code on the nameplate. With its ‘Made in Europe’ and low carbon footprint credentials, the Dyneo+ motor is eligible for Energy Savings Certificates, also known as White Certificates, generating government aid through the energy savings made. This makes for easy financing, meaning considerably faster return on investment, on top of the accrued energy savings Optimized productivity of industrial refrigeration Environmental compliance, energy performance and top-notch reliability are some of the key features that ensure Dyneo+ motors represent a drive solution that are perfectly suited to the optimized productivity needs of industrial refrigeration processes.

It is important to properly size a water heater to meet the needs of a business or household and ensure optimum efficiency. As a result, Ariston has introduced a comprehensive guide to its portfolio of high-quality vented, unvented and instantaneous electric water heaters, outlining which models are best suited for a range of domestic and light commercial applications throughout the UK. The guide can be found in the new Ariston hot water brochure. Ariston’s water heating guide makes it simple to identify which product is best suited for a project, by cross referencing the types of outlet with the intended levels of use. For example, it identifies that for a single basin with a light level of water usage, the wall-mounted, 5-liter Piccolo would be adequate. Similarly, for heavy use applications looking to feed three wash basins or a kitchen sink, 30-liter capacity Andris Lux or Andris Lux Eco water heaters should be installed. Wash basins For projects involving wash basins, products such as the Andris Lux, Andris Lux Eco and Andris R can be fitted, as can the Piccolo or Aures Slim Multi instantaneous electric water heater. The guide identifies which capacity unit should then be used, depending on light, medium or heavy levels of water use. Similarly, as the number of wash basins increases, the size of the water heater(s) used has to follow suit Similarly, as the number of wash basins increases, the size of the water heater(s) used has to follow suit. So, whereas a 6-liter product could cater for a single basin at medium usage, two basins would require a 10-liter Andris Lux or an Aures Slim Multi instantaneous unit for the same level of use. Larger sinks Although the products already mentioned can feed a kitchen sink if required, once there are multiple sinks being used frequently, units with capacities over 30-liters are recommended. Ariston’s Velis Evo, Velis Evo Wi-Fi and Pro1 Eco models are best suited here, with their respective 45-liter and 50-liter versions suitable for medium use or their larger 80-liter counterparts handling heavy water usage with ease. Showers This requires 45 to 50-liter units so, once again, the Velis Evo Wi-Fi and Pro1 Eco are recommended, moving up to the 80-liter versions, should multiple showers and basins need filling. Additionally, as water usage increases (e.g. in multiple occupancy properties), Ariston recommends using the 80-liter models of these platforms, or using the 100-liter version of the Pro1 Eco for applications where showers and basins will be used in succession. Baths A restaurant could utilize a Pro1 Eco storage water heater in the kitchen to cope with high levels of usage Finally, for applications with a bathtub, either Ariston’s 80-liter Velis Evo Wi-Fi or 100-liter Pro1 Eco are recommended; as the average bath holds 80 liters of water (with at least 75% being hot) a large capacity unit is required - especially if it will be required to supply other outlets, such as a kitchen sink, at the same time as the bathtub. Installers should also note that different models can be combined for different areas of a property or business. For example, a restaurant could utilize a Pro1 Eco storage water heater in the kitchen to cope with high levels of usage, whereas smaller areas with less water demand, such as washrooms, could be fitted with Aures Slim Multi instantaneous water heaters. Similarly, an office could have a small Andris Lux Eco beneath its kitchen sink, while a larger capacity Velis Evo Wi-Fi electric storage water heater supplies its shower and washrooms. electric water heater Victoria Gutierrez, Marketing Manager at Ariston, added: “Choosing the correct electric water heater will undoubtedly result in cost and energy savings for end users; however, the size of electric water heater is determined by how many people are going to be using it, as well as the reheat times and frequency of use. Our new guide simplifies the product selection process so, whatever size or capacity is required, it will be easy to find the water heater in our portfolio best suited for the project in hand.”

The past six months have been busy for those in HVAC as offices are updated and made safe for people to return. In addition to the various standard checks that need to be carried out, more care is being taken in relation to air movement and filtration to prevent the spread of disease. There is evidence that at least some of the COVID-19 virus can remain suspended in the air and infectious for up to 3 hours. While this is not the main form of transmission, it is vitally important, especially as we are seeing a second increase in infections, that all measures are taken to prevent the spread of the disease. Sick building syndrome In addition to the fundamental elements of HVAC in public buildings, the sector should be looking to the future of technological use; whether COVID-19 is completely wiped out or lingers in the population, we may be at risk of more new diseases in the future. Although maintenance is one of the least visible of building services, it has long played an important role in ensuring the health of buildings. Decades ago, the concept of sick building syndrome was first introduced, showing quite how important our environment is to health. Now, we are being reminded of this on a daily basis in ways that have never been under such scrutiny. We are suddenly hyperaware of what we have touched and who else is breathing our air. In many ways, this new awareness of the unseen is a boon for the sector that has so long been behind-the-scenes, but it also puts it to the test. Potentially stagnant pockets There are numerous recommendations from experts on how to increase safety Governmental guidelines have not specifically required that ventilation and air conditioning be increased in the workplace. Yet, there are numerous recommendations from experts on how to increase safety. At the low-tech end of the spectrum, the use of ceiling and table fans to increase movement in potentially stagnant pockets of air has been suggested. At the other end, technologies that have long been growing in popularity, such as remote monitoring, will really come into their own in the coming months. A particular challenge for the industry as workers return to the office under social distancing guidelines will be accessing certain areas for maintenance. For as long as the virus remains in the population, risk assessments for work will be more complex and non-essential jobs will likely be put on hold where possible. Optical remote sensors Intelligent technology and monitoring systems are already driving the market and will play a role in minimizing contact with others when visiting a site. There is already a great range of tools available: wired sensors, wireless sensors, and optical remote sensors. These allow organizations to monitor vibration, temperature, acoustics, and the power of numerous assets remotely and in real-time. Any issues can be addressed as soon as they arise, minimizing the cost and time that an engineer may need to be in the building. Installing these technologies while buildings are still unoccupied or only partially occupied will also reduce the risk of exposure of engineers to the virus and will improve the efficiency and prolong the life of important assets. Whether a second lockdown takes place or not, these tools will protect building services. Motion-Activated air conditioning Other sensor-based features such as motion-activated air conditioning also have great potential Other sensor-based features such as motion-activated air conditioning also have great potential. These can manage the new hygiene anxiety which pervades public places at the moment. In the longer term, they can be a means of building sustainability practices into the workplace, using power only when needed. Internet of Things (IoT) features such as occupancy sensors have long been growing in popularity to create buildings which are more energy-efficient and promote productivity. Many of these features are demonstrating added value during the pandemic. Occupancy sensors, for example, can be used to ensure that buildings do not exceed safe numbers for social distancing. HVAC systems will be integrated ever further into the IoT approach. Some features of virus reduction, however, have posed a challenge for systems. Air conditioning systems Air conditioning systems, for example, can best reduce the risk of viral transmission through increasing the amount of air which is brought in from the outside into the systems. This will reduce the amount of recycled air but will also increase the temperature fluctuations within the buildings. Other recommendations have included reviewing ventilation strategies, increasing ventilation operating times, deep cleaning filters, and replacing filters more often. Cutting corners on anything which reduces the risk of virus spread will only be a greater loss to the client All of these can potentially see an increase in time and cost required by the client at a time where many companies have been stretched financially. Cutting corners on anything which reduces the risk of virus spread will only be a greater loss to the client in the long run if their employees lose time to illness but it still may be a temptation. Strong working partnership FM providers must work closely with clients to understand their individual fears and needs in such turbulent times. For Anabas, we believe demonstrating expertise and experience is a means of reassuring organizations that they are in safe hands. The future of the pandemic is still unpredictable. While its elimination is hopeful, it is still well worth the investment for many organizations to install the tools which minimize the risk of infection of COVID-19 - or any future infections. Clients are looking for certainty in an uncertain world and data-driven insights and real-time monitoring are ideal ways to provide this. However, the reassurance that comes with a strong working partnership will also be more important than ever. Communicating developments and what they mean for the client, as well as assuring them their priorities are understood can set a provider apart.

Across the globe, annual food loss amounts total to approximately 1.3 billion tons of waste and 4.4 gigatons of greenhouse gas (GHG) emissions. To put that in perspective: If food waste were a country, it would rank as the third largest GHG emitting country in the world, surpassed only by the United States and China. The average supermarket, which brings in about $35M in annual revenue, will see $526,590 worth of food waste and 3,600 MWh worth of wasted energy use, where about 2,000 MWh is used for refrigeration—the equivalent of 170 households. SaaS for temperature monitoring Clearly, there is both an economic and sustainability burden to food loss besides the revenue loss and environmental impact. Luckily, this burden can be eased when using Software as a Service (SaaS), like food temperature monitoring. Supermarkets who monitor their food temperatures will improve their margins and overall profitability by selling food at its full price rather than marked down due to over ripening or close to expiration date. This, in turn, will deliver improved customer satisfaction because supermarkets will be able to continue to stock fresh food while minimizing the sale of old and ripened provisions.Supermarkets who monitor their food temperatures will improve their margins and overall profitability There are many benefits of using SaaS to improve supermarket efficiency, which can help to reduce food waste and lower energy costs in countless supermarkets worldwide. Many of the roughly 50,000 food retail locations that utilize electronics controllers use some level of SaaS technology like Alsense Food Retail Services, the newest cloud offering from Danfoss Climate Solutions for supermarkets and food retail applications. Alsense Food Retail Services is a sustainable, scalable, and secure modern platform that delivers tangible data to improve operational and energy efficiency while optimizing the performance of food retail operations. Its technology is engineered to provide supermarkets with actionable insights that allow you to track refrigeration asset performance, respond to alarms, integrate 24/7 monitoring, reduce energy consumption, and more to deliver savings as high as a 40% reduction in food waste and 30% decrease in energy costs. Examples of food loss prevention with Alsense Food Retail Services The sensor in the meat fridge notices a high temperature and submits an alarm to the cloud The alarm is analyzed by the Danfoss Enterprise Service Team (Managed services) The reason for the alarm is determined and a service provider is contacted The service provider is dispatched to the supermarket to fix the issue in the meat fridge to avoid food loss Danfoss’ advanced algorithms detect if the refrigeration systems are running efficiently or if they are over consuming energy Alsense Food Retail Services is a sustainable, scalable, and secure modern platform that delivers tangible data to improve operational and energy efficiency while optimizing the performance of food retail operations aktiv & irma, a supermarket in North Germany, has shown significant savingsWithout SaaS, the store’s ROI will take much longer than if you rely solely on the hardware as part of the Alsense Food Retail Services pilot program. In collaboration with Danfoss, they installed a solar photovoltaic system, storage system, and a charging station for guests. All major assets in the supermarket system are linked through the Alsense Food Retail Services cloud to manage loads and eliminate unnecessary peaks to best use each store’s energy. Regulating energy levels is accomplished through a variety of methods that offer potential savings: Load shifting: As high as 20 kW in additional peak reductions ($1,758.30 potential savings). Compressor curtailment Solar: 112 MWh electricity produced ($16,410.80 savings) Battery: Grid demand reduced by 40 kW ($3,516.60 savings) Peak load shaving: Charging station is throttled if needed to maintain target max peak level in the store. ($2,344.40 potential savings) aktiv & irma saved about 15% in additional energy costs and reduced over 70 tons of CO2 for a total savings of $20,168.80 compared to other supermarkets. For supermarkets that are considering marrying SaaS with their hardware expenditure, the return on investment (ROI) will depend largely on their level of SaaS investment. Without SaaS, the store’s ROI will take much longer than if you rely solely on the hardware. To put it simply, the more robust the SaaS program, the quicker supermarkets will see a return on the overall system investment. Alsense Food Retail Services? A zero-net, even net positive, billable energy supermarket is possible. The prerequisites to make these savings happen are based on energy efficiency, particularly reducing overall consumption and onsite heat and electricity generation and storage. Energy arbitrage services can enable energy bill optimization. Essentially, this means that energy can be stored in a battery and used when prices in the grid are high.Precooling can also be used to cool down cabinets before prices increase Precooling (curtailment) can also be used to cool down cabinets before prices increase. Another option is to turn off compressors for as long as possible when the energy prices are high. This means temperatures will drift upwards, so turn on the compressors before the temperature compromises food quality. Lastly, supermarkets have further potential to balance the grid via fast Frequency Response, peak Load Shifting, and seasonal Buffering. SaaS technology, like Alsense Food Retail Services, is a strong compliment to hardware assets that can help supermarkets achieve higher profitability and food loss and waste reduction. If a supermarket aims to go zero- or positive-net, the solution is to invest in both hardware and SaaS.

The impact of COVID-19 has hit all areas of industry in a variety of different ways; with mass redundancies, restructures and the need for diversification now dominating the headlines. It has also made a lot of people question their own careers and what is important to them; in fact, Google searches for the term ‘career change’ are up more than 500% on this time last year. With more than half of the heating and plumbing industry’s workforce due to retire in the next decade, and so many people considering a career change (either through choice or necessity), is there a window of opportunity for the heating engineering and plumbing industry to attract men and women to the industry? Why is there a need for recruitment in the industry? In 2017, the Gas Safe Register’s ‘Decade in Review’ found that the average age of heating installers was 55, with over half of respondents being this age or older. The report also found that over 50 per cent of engineers are concerned about keeping up with advancing and unfamiliar technology. Over the next decade, this aging With more than half of the heating and plumbing industry’s workforce due to retire in the next decade, and so many people considering a career changeworkforce will begin to reduce their working hours or retire completely. With fewer young people deciding to train as a heating installer, the industry will quickly lose valuable experience as the workforce diminishes. In addition, a survey by the Centre for Ageing Better found that, of 500 employers, only 20% have considered how they will tackle an aging workforce, and 24% have no strategies in place. How can heating installers promote their career path? As of October 2020, the UK unemployment rate has risen to its highest level (4.5%) in over three years. According to the ONS, an estimated 1.5 million people were unemployed between June and August, while redundancies stood at 227,000. Of those now facing unemployment, about 300,000 are aged 16-24. With so many young people out of work, and plenty of adults looking to make the move from an office-based role to one that’s ‘more rewarding’, a career in the trade could be an attractive option. But, how can heating installers market themselves as a prosperous career path to these people? Be positive on social media Social media platforms like Twitter, Facebook, Instagram, and LinkedIn have provided installers with a way to market themselves to customers, share their successes, and connect with others in the industry. This is all great, but often heating installers use social media to vent their frustrations, complain about long hours and feeling tired, or even complaining about customer behaviour. While this is absolutely understandable (we all need to let off steam from time to time), this kind of content should be shared on private accounts only seen by family and friends. It may be worth setting up a second account which can be seen by the public and only share positive content there. This will show followers (who are potential recruits and customers) the more positive aspects of the career. Talk about benefits and progression opportunities When attracting young people to any profession, you need to emphasize the opportunities it offers in terms of progression, potential earnings, and other benefits such as being self-employed and therefore being able to manage your own hours and holidays. Offer an apprenticeship scheme By offering a paid apprenticeship scheme you can attract both young people and older career changers who have financial responsibilities to meet. You know better than any that it takes time to train as a heating installer, as well as a lot of on the job experience, and a paid apprenticeship could make the career a viable option for people with financial commitments. Make it clear to new recruits that they will be supported and mentored throughout their training. Will the Green Homes Grants scheme help the heating industry? Finally, it is important to address the government’s Green Homes Grants scheme which began accepting applications in September and will be open until 31st March 2021. The scheme offers £5,000 vouchers to homeowners in England to cover two-thirds of the cost of energy-saving improvements such as improving insulation and installing renewable heating systems like heat pumps, biomass boilers, and solar thermal panels. In addition to encouraging homeowners to reduce their carbon emissions in line with the government’s target of reaching net-zero emissions by 2050, the scheme Google searches for the term ‘career change’ are up more than 500% on this time last yearis also intended to boost employment. The increased interest and investment in the renewable energy sector could indeed open up more opportunities for the unemployed, but as the scheme is only open until March 2021, this does not seem to be a particularly long-term approach. Homeowners cannot use the grant to install a more efficient gas or oil boiler, so it is unlikely to help the heating industry to attract recruits who will become traditional boiler installers, but it may kickstart the renewable heating industry and encourage existing heating professionals to diversify their skillset. Of course, there is always the possibility that increased awareness of the need to reduce carbon emissions and make our homes more efficient will have a knock-on effect for the boiler installation industry, but only time will tell. Use digital advertising When people are looking for a job, or even when they are just passing the time at home during lockdown, they will usually be online. When you have a job opening or an apprenticeship on offer, be sure to advertize on digital platforms including job posting websites, LinkedIn, search engine and social media advertising. Be open to diversity If the industry is only open to attracting men of a certain age from a certain background, the number of potential recruits reduces rapidly. The heating industry is one of the least diverse, particularly in terms of gender as only 0.4 per cent of Gas Safe registered engineers are female. Heating installers and employers not only need to be willing to hire a more diverse workforce, but they also need to be proactive in their efforts to attract candidates to ensure everyone feels welcome and supported in the industry.

Data is playing an increasingly important role in smart buildings. Analysis of building system data is guiding an expansion of capabilities in the smart building environment, making building systems - including HVAC - more efficient, effective and smarter. The growth of intelligence in the HVAC market was among the more prominent industry trends in 2020. This article will revisit some of the year’s most popular articles on HVACinformed.com that focused on the trend toward more intelligent systems. "I don’t think many would disagree that the most talked about trend in the HVAC market is smart technology,” says Chris Windass of Incentiv Tec in an HVACinformed.com Expert Panel Roundtable article. “Smart technology like mobile apps allow building managers to control HVAC technology from one centralized point. With this smart technology, HVAC will be able to identify and alert building managers when maintenance is needed or assets have failed to operate.” smarter building technology A Johnson Controls survey found that 77% of organizations planned to make investments in energy efficiency and smarter building technology in 2020. “A complete overhaul of legacy systems is not necessary as small investments today can help position a facility to more easily adopt technologies at scale in the future,” says Lisa Brown, Senior National Director of Municipal Infrastructure and Smart Cities at Johnson Controls. More Intelligence in Home Systems Google’s Nest smart thermostat is offering a new capability that will alert homeowners of problems “As a first step, it’s important for building owners to conduct an assessment and establish a strategy that defines a comprehensive set of requirements and prioritizes use-cases and implementations. From there, incremental investments and updates can be made over a realistic timeline.” Smart systems are also a big part of residential HVAC systems. For example, Google’s Nest smart thermostat is offering a new capability that will alert homeowners of problems with the operation of their HVAC systems based on artificial intelligence (AI) algorithms that analyze system performance. The technology will empower Nest Learning thermostats to provide “early warning” of HVAC problems and even direct homeowners to a repair company. Remote Troubleshooting Emerges Sensors are another element of smart buildings. The Internet of Things (IoT) has enabled more sensors of different types to be deployed in more locations throughout the building easier than ever before. The point of installing and using IoT sensors is to gain deeper insight into how buildings are performing, and ensure buildings are healthier, more productive for people to work in, more effective to run and more energy efficient. In-room sensors, such as temperature, air quality and occupancy, work with the IoT to improve building performance. The benefits of IoT sensors are that they are easy to install, both physically and from a commissioning perspective. Remote troubleshooting is another smart capability that is generating interest. CoolAutomation’s Remote HVAC Service Solution enables HVAC service providers to remotely troubleshoot issues by analyzing real-time and historic data trends and analysis. Communicating in Smart Buildings They receive automatic error and anomaly notifications in their office or on their mobile phones They receive automatic error and anomaly notifications in their office or on their mobile phones. “The remote service solution provides the tools that HVAC service providers need to offer remote services to their existing clients while attracting new customers who understand the value of remote service for their business,” says Roy Muchtar, VP of Products at CoolAutomation. Communication is a central aspect of smart building systems, and now there’s a better option: a high-speed wireline communication standard called HD-PLC that is developed specifically for today’s industrial IoT and smart building applications. In 2017, after careful evaluation of various technologies, LonMark International adopted HD-PLC as its new channel standard. smart home standards And last October, the Consumer Technology Association (CTA) approved ANSI/CTA 709.8 LON HD-PLC (High Definition Power Line Communication) as a new standard by the American National Standards Institute (ANSI). Also related to communication, the Zigbee Alliance seeks to promote collaboration in the Internet of Things by creating, evolving, and promoting universal open standards that enable all objects to connect and interact. A quick search also provides a manual, wiring diagram and video training content for that specific unit Their effort took off when Amazon, Apple, Google and the Zigbee Alliance announced an industry working group in December 2019 to take the “best of market” technologies from leading smart home standards, portfolios and ecosystems and to develop a “super spec” that will be open, inclusive and a significant industry shift in the smart home market. The Project Connected Home over IP (CHIP) is looking to unify the environment, under one technology, one certification program and one logo. Training Technicians Using Technology Technology is also helping to fill the skills gap in the HVAC market. The XOi Vision platform helps on-site HVAC technicians in three ways. One is to “capture” images and videos. A technician can take a picture (with a smart phone or tablet), and the system’s machine learning can extract the text from the nameplate of a unit in the field, interpret the type of name plate, and provide full model number, serial number and other information about the unit, which is relayed automatically to the technician in a text message. A quick search also provides a manual, wiring diagram and video training content for that specific unit.

The year 2020 will forever be remembered for the global pandemic that transformed almost every aspect of our lives. COVID-19 impacted the HVAC market, as it did most other business sectors. However, HVAC also rose to a new level of prominence at the center of the pandemic, both as a potential cause of virus spread and as a source of solutions to fight the virus. This article will highlight the intersection of HVAC and COVID-19 based on articles published during 2020 at HVACinformed.com. Impact Of COVID On HVAC In an HVACInformed.com Expert Roundtable Discussion, several industry experts weighed in on the impact of the coronavirus pandemic on the HVAC market. Contractors were either not allowed to or were reluctant to enter people’s homes for sales and installation purposes, resulting in decreased demand and, ultimately, decreased sales. However, during extraordinary times, it was encouraging to see a renewed focus on something the HVAC industry has been delivering for years – comfort. Survey By Air Conditioning Contractors of America (ACCA) A survey by the Air Conditioning Contractors of America (ACCA) gathered insights on the effect the coronavirus pandemic is having on the HVAC industry. The survey in March indicated 65% of respondents expected COVID-19 to translate into long-term business viability concerns; 9% were concerned their businesses may not survive. HVAC industry employees were included among “Essential Critical Infrastructure Workers as designated by the U.S. Department of Homeland Security (DHS). Roles Of Ventilation HVAC technicians and companies have risen to the challenges of social distancing and wearing masks There was increasing awareness of the role of air ventilation in fighting the virus. There has been renewed interest in air filtration, not to mention the benefits of UV-C to mitigate to mitigate germs circulating in the air. Furthermore, HVAC technicians and companies have risen to the challenges of social distancing and wearing masks as they are invited into customers’ homes and businesses during the pandemic. Resources To Maximize HVAC Systems ASHRAE developed resources to help maximize how HVAC systems can have a positive impact as the coronavirus spreads. The society recommends strategies such as dilution ventilation, laminar and other in-room flow regimes, differential room pressurization, personalized ventilation, source capture ventilation, filtration (central or unitary), and ultraviolet germicidal irradiation (UVGI) (upper room, in-room, and in the airstream). Ultraviolet Light 2020 saw an unprecedented surge in demand for germicidal solutions. UV-C light is a short-wavelength, ultraviolet light that kills germs by inactivating a microorganism’s DNA. Although UV-C is effective in killing other varieties of coronaviruses, such as SARS and MERS, scientists do not yet know about the impact of UV-C on COVID-19. The Tennessee Valley Authority (TVA), the power provider in the United States, is offering incentives to businesses and schools to install UV-C germicidal lights to fight germs in indoor air. Role Of HVAC In Virus Spread Whether HVAC could contribute to virus spread was a repeated topic of interest. One theory goes that air conditioning, by removing humidity from the air, may enable infectious droplets to linger longer than they would outdoors or in another space where humidity is higher. More humidity can weigh down viral droplets as they float through the air. Minimize The Spread Of The Virus ASHRAE opposes the advice and asserts that keeping air conditioners on during this time can help control the spread of the virus Does it make sense, therefore, to turn the AC off to minimize the spread of the virus? according to ASHRAE, which officially opposes the advice not to run residential or commercial HVAC systems. In fact, ASHRAE asserts that keeping air conditioners on during this time can help control the spread of the virus. Also related to virus spread, the Centers for Disease Control and Prevention (CDC) reported on a case under the title “COVID-19 Outbreak Associated with Air Conditioning in a Restaurant, Guangzhou, China, 2020.” Research Trends And The Future The need for more research will continue after the pandemic. Broadly speaking, we know that crowded spaces with poor ventilation and/or low humidity levels tend to promote virus spread, that filtration can help to remove the virus, and that measures such as UV-C radiation can help to disinfect indoor air. More study is needed, and more time is needed to complete those studies and expand our base of knowledge on this important subject.  Preventing COVID Panasonic has conducted research that verifies that hydroxyl radicals contained in water can inhibit the novel coronavirus (SARS-CoV-2). The nano-sized electrostatic atomized water particles are generated by applying a high voltage to moisture in the air. Here is a statement from the company, "While Panasonic makes a wide range of products that generate these types of free radicals, none of these products has been tested for efficacy in the inhibition of the SARS-CoV-2 virus on surfaces or in the air.” Innovative approaches to fighting COVID include HVAC-equipped smart, glass-paneled bus stop shelters that that help to prevent pandemic spread in the Seongdong district in northeastern Seoul, South Korea. Ventilation And Air Filtration As schools worked to reopen safely in the midst of a global pandemic, HVAC was at the center of the mission. Adequate ventilation and effective air filtration are critical elements to ensure safe indoor air quality for educational institutions. Many schools are housed in older buildings that may not have been adequately maintained. Transforming them to address the new challenges of minimizing exposure to the novel coronavirus is that much more difficult.

Sustainability and environmental impact are core issues of the HVAC market in 2020 or any year. During the last year, HVACinformed.com has addressed multiple facets of sustainability in some of our most popular articles. This retrospective will highlight some of the sustainability articles published during 2020 at HVACInformed.com. An HVACInformed.com Expert Panel Roundtable commented on various aspects of sustainability, including the responsibility of HVAC manufacturers to develop more sustainable, energy-efficient products that can reduce a building’s reliance on fossil fuels. Energy consumption pattern Honeywell has launched a platform that incorporates newer technology. Combining self-learning algorithms with building automation, Honeywell Forge Energy Optimization is a cloud-based system that analyzes a building’s energy consumption pattern and adjusts its settings. Heat networks, or district heating, are becoming an ever-greater part of the industry’s involvement Pete Mills of Bosch Commercial & Industrial outlines how cities are using ‘heat networks’ to achieve carbon emission targets in the United Kingdom. Heat networks, or district heating, are becoming an ever-greater part of the industry’s involvement in larger-scale schemes. The ability to help the decarbonization of heat both now and in the future has made them an attractive solution to the new-build sector, as well as those undergoing deep renovation works. Centralized heat generator Generally, heat networks are defined as a system of supply pipes with a centralized heat generator (Energy Center) that serves multiple domestic or non-domestic dwellings. These are usually in different buildings, but sometimes within a single large building like an apartment block or a university campus. Some U.S. cities are taking the lead to make building performance standards mandatory, thus providing additional incentive for customers to invest in new, more efficient and climate-friendly HVAC technologies. New York City has deployed its Carbon Mobilization Act, which will cut six million tons of CO2 annually by 2020. Washington D.C. adopted the first Building Energy Performance Standard, which will reduce energy use in buildings by more than 20%, thereby lowering carbon dioxide emissions by a million tons annually. Improving environmental performance Newer buildings tend to be designed to be ‘green’, but what about older existing buildings, which still represent the largest share of environmental impact? There is more work to be done in the retrofit sector; and improving environmental performance of older buildings often involves ‘deep retrofits’ that are costly and impact multiple factors inside a building. In the COVID-19 era, there is also growing concern about needs such as circulating outside air, increasing humidity, and improving filtration systems even as older buildings seek to become greener. The consistent theme is a need to work toward better-designed, more energy efficient and healthier buildings The consistent theme is a need to work toward better-designed, more energy efficient and healthier buildings. The California Air Resources Board (CARB) is moving forward with rulemaking that sets limits and deadlines to decrease the use of refrigerants with global warming potential (GWP) in the commercial refrigeration market and in the residential and commercial stationary air conditioning equipment markets. Air conditioning systems California regulations are widely expected to influence the direction of other states seeking to regulate GWP of refrigerants. The addition of biodiesel lowers the carbon content (and thus the environmental impact) of heating oil. The U.S. Environmental Protection Agency says biodiesel reduces greenhouse gas emissions, including nitrogen oxide. The process of making biodiesel from renewable and organic sources also boosts the environmental profile. The Wyss Institute at Harvard University has developed an evaporative cooling system that uses a specially coated ceramic to cool air without adding humidity. Researchers say the approach can yield more affordable and environmentally friendly air conditioning systems for the future.

The nationwide lockdown in November, which was necessary due to the high number of infections in the second corona wave, has been accompanied by considerable restrictions. It is therefore all the more important to continue to secure the indispensable work in public institutions and especially, teaching in schools. In order to provide a decisive solution to the problem, Viessmann has developed a new air ventilation unit, the Vitovent 200-P. This is a unique hybrid ventilation unit that provides rooms with a continuous supply of fresh air and simultaneously cleans the air. Continuous air circulation Constant air circulation reduces aerosols and supplies closed rooms with fresh outside air again and again, so that pupils and teachers are best protected against the virus and learning performance is improved. "As a 103-year-old family business, we are committed to designing living spaces for generations to come," says Viessmann Co-CEO Maximilian Viessmann. A direct and continuous air circulation is guaranteed with a fresh air supply at floor level “Right now it is crucial that we quickly and pragmatically safeguard our children to maintain a part of their social life and access to education in these challenging times.” Vitovent 200-P uses the so-called displacement ventilation principle: A direct and continuous air circulation is guaranteed with a fresh air supply at floor level which then rises due to heat exchange with the occupants’ bodies. Comfortable learning atmosphere Consequently, used air rises to the top and travels into the units and is cleaned there, before being returned into the room as fresh air at floor level. The permanent supply of fresh air with heat and moisture recovery ensures a comfortable learning atmosphere and good air quality, even without window ventilation. Vitovent 200-P units have already been successfully tested in a pilot project at the Hans-Viessmann Vocational School in Frankenberg, North Hesse. The feedback from students and teachers has been overwhelmingly positive. In particular, it was positively highlighted that the unit runs very quietly and creates a comfortable indoor climate- it was also noted how in the prior absence of frequent ventilation, an additional health risk in winter when outside temperatures are very low, not only did the indoor air dry out excessively, but the schools' energy consumption and CO2 emissions were driven up too. Short term development Viessmann successfully demonstrated that the company was prepared to fulfill its social responsibility The devices can be retrofitted easily and at low cost by replacing a window pane with an isopanel. Thus, they offer the possibility to keep heavily occupied lounges and public facilities open despite a generally high risk of infection. The Viessmann Group together with the Viessmann Foundation announces that it will donate the first 50 Vitovent 200-P air cleaning units worth a six-figure sum to schools and social institutions, and will assume the full cost of installation. The company is thus fulfilling its purpose ‘We create living spaces for generations to come’ to a great extent. Already at the beginning of the outbreak of the pandemic, Viessmann successfully demonstrated that the company was prepared to fulfill its social responsibility and made a tangible contribution to the community through the short term development and provision of respiratory ventilators, mouth and nose masks and disinfectant - all of which are summarized as ‘ViAid’.

Boiler manufacturers Baxi Heating and Worcester Bosch have installed hydrogen burning boilers at ‘HyStreet’, in specially built demonstration houses at DNV GL’s specialist test site at Spadeadam in Northumberland, United Kingdom. The site has been used to complete over 200 tests, researching and proving the safety of converting homes and gas networks to hydrogen. The project is part of H21, a Network Innovation Competition project sponsored by Ofgem. Northern Gas Networks is leading the project with partners Cadent, Scottish Gas Networks, Wales & West Utilities, National Grid, DNV GL and the Health and Safety Executive’s science division. Combi boilers installed H21 is demonstrating how existing natural gas networks can be re-purposed to safely carry 100% hydrogen H21 is demonstrating how existing natural gas networks can be re-purposed to safely carry 100% hydrogen. For the first demonstration, both Worcester Bosch and Baxi Heating have installed combi boilers into the houses on HyStreet. The boilers have been developed as part of the UK Government-funded Hy4Heat program, which is also supporting the development of hydrogen-ready gas cookers, fires and gas meters. As around 85% of UK homes currently rely on natural gas for heating and hot water supply, re-purposing the natural gas grid for use with hydrogen would mean a low disruption option for householders to decarbonize their heating, without the need for extensive changes to their existing system. Tackling carbon emissions due to home heating Tackling carbon emissions resulting from home heating is utterly essential and one of the most difficult challenges in achieving net-zero emissions, given the need to make adaptations in almost every home. A growing library of studies and reports conclude that all viable scenarios for the UK to hit net-zero include hydrogen as a vital component. That is why Government and industry are working on various projects across the United Kingdom. Wide deployment of hydrogen boilers Tim Harwood, Northern Gas Networks’ Project Director for H21, said “Seeing the boilers in situ at Spadeadam is an exciting step in the journey to realizing our goal of a gas network transporting 100% hydrogen to customers. The hydrogen boiler looks and feels just like the natural gas version we all have today and is just as user-friendly, showing that a transition could cause minimal disruption to customers.” Dan Allason, Head of Research and Innovation, at DNV GL’s Spadeadam Research and Testing, said “Eight out of ten homes in the UK use a gas boiler to heat their homes and provide hot water and replacing all gas boilers with electric alternatives could be extremely costly. Both of the boiler manufacturers have developed options with their hydrogen ready prototypes to assist the switch to a lower carbon alternative.” Proof of concept and public acceptability We are delighted to be able to demonstrate this innovative new technology in a real-life setting in the UK" Dan adds, “Having these fitted to the HyStreet demonstration project at Spadeadam gives gravitas to the proof of concept and public acceptability of appliances such as these. The boilers are one of the first important steps.” Karen Boswell, Managing Director of Baxi Heating, said “This is an important step forward on our hydrogen journey and we are delighted to be able to demonstrate this innovative new technology in a real-life setting in the UK.” Zero-carbon alternative to natural gas Carl Arntzen, the Chief Executive Officer of Worcester Bosch commented “It is fantastic to see our prototype hydrogen boiler running successfully at this demonstration site. The boiler has operated seamlessly in its first month of operation and continues to provide both heating and hot water.” Carl adds, “It proves that hydrogen gas has great potential as a zero-carbon alternative to natural gas for heating and hot water in the UK and beyond. These initial tests are incredibly encouraging and will hopefully give key decision makers confidence to deploy hydrogen gas as a fuel for the future.”

New technologies continue to drive change in the HVAC market. HVAC’s image as a mature and stable industry can overshadow the high level of innovation taking place. Meeting environmental challenges and creating more cost-efficient systems are among the forces fueling the change. We asked our Expert Panel Roundtable: What will be the next big product trend in the HVAC market? 

Welcome to our Expert Panel Roundtable, a new feature of HVACInformed.com. We will be asking timely questions about the HVAC market and seeking out experts in the field to provide responses. Our goal is to promote a useful exchange of information on a variety of topics and to create a forum for discussion of important issues facing the industry. Launching this new feature in the middle of a global pandemic made choosing our first question quite easy. We asked our Expert Panel Roundtable: What has been the impact of the coronavirus pandemic on the HVAC market?
