In 2020, the support programs of the Federal Office for Economics and Export Control (BAFA) and the Reconstruction Loan Corporation (KfW), which were increased as part of the climate package, ensured a significant market recovery. At the beginning of 2021, the Federal funding for efficient buildings (BEG) will come into effect, at least in part (individual measures in the grant variant) and will replace the previous programs. Federal funding for efficient buildings (BEG) Most of the funding conditions that have been in effect, until now, will remain in effect. “The BDH welcomes the merging and simplification of the funding framework,” stated BDH (Federation of German Heating Industry) President, Uwe Glock. It is now a matter of permanently securing the financial resources of the BEG in order to give potential modernizers planning security. In connection with the new funding, the BDH (Federation of German Heating Industry) points out that in the event of modernization of existing buildings, not only the heat generators, but also the heat transfer and heat distribution fall under the new funding. These include, for example, replacing radiators or replacing thermostatic valves. Funding includes all components of heating systems The new BAFA funding program, ‘Energy advice for non-residential buildings, facilities and systems’ started on Jan 1, 2021 “A modern heating system consists of several components: heat generation, heat distribution, heat transfer and storage. In order for a heating system to develop its full potential for efficiency, these components must be perfectly coordinated. The funding takes this into account,” said Christian Ludewig, member of the BDH (Federation of German Heating Industry) board. The investment costs and the costs for installation and commissioning, as well as the costs of the necessary environmental measures are eligible. The new BAFA funding program, ‘Energy advice for non-residential buildings, facilities and systems’ started on January 1, 2021. Guidelines for funding programs to be merged In the course of the new funding for non-residential buildings, the guidelines for the programs, including ‘Energy advice in medium-sized companies (EBM)’ and ‘Energy advice for non-residential buildings by municipalities and non-profit organizations (EBK)’ will also be merged. In addition, the contracting orientation advice is added. A comprehensive funding scenario is now also available for industrial modernizers.

An experienced team of HVAC technical specialists is launching a new service to provide design expertise and systems for commercial developments. UnderFloor Climate Management (UFCM), which is a part of the Polypipe group, will work with architects, developers, and contractors to help deliver integrated underfloor heating systems for commercial projects including residential apartment buildings, hotels, student accommodation, and office developments. Commercial heating market The service is headed up by Rachel Smith, UFCM managing director, who has a wealth of experience within the built environment sector. Andrew Coy, who has years of experience in developing heating products and systems for the residential and commercial heating market, joins the team as Commercial Director. UFCM has been developed as a solution to the fast-evolving landscape of the HVAC sector with Net Zero Carbon targets, a move towards more renewable energy sources, and a changing building design process drastically affecting the demands on heating design. These elements will impact the requirements of developers looking to maximize the opportunities of the population growth and fast-evolving skylines across the UK’s major city centers. Renewable heating sources The UFCM team will work with architects, developers, and contractors to advise on project design There is now a concerted move away from legacy heating systems that are offering diminishing performance towards systems compatible with the available smart control technology, renewable heating sources such as ground, and air source heat pumps and the design demands of achieving the most living space for sale on increasingly small building footprints. The UFCM team will work with architects, developers, and contractors to advise on project design and specify the best design solution using a comprehensive range of underfloor heating systems for the project brief. Building heating systems Rachel Smith, Managing Director, UnderFloor Climate Management: “UFCM is here to work with architects and consultants to design and deliver sustainable, usable, and comfortable heating systems for the new generation of residential tall buildings, and large developments that are transforming how we live, work and socialize in UK cities.” “Our team offers technical expertise unrivaled in the industry, tried, and trusted systems and a thorough understanding of commercial construction markets. We are already working with some of the UK’s major developers who see the value and longevity in using new technology and design methods and our team is going to be delivering large building heating systems that are fit for modern living and comfort and the changing face of office work.”

How grooved solutions have been making contractors and engineers reimagine the way they construct risers in vertical buildings? Enter into the right pub, or head to a city’s museum or town hall, and you can often find a picture of how the surrounding area used to look. An image from twenty years ago and the difference isn’t too vast. Fifty years back and there’s a definite change. A picture from over a hundred years ago and it’s practically unrecognizable. And what’s the common theme running through these images? Cities are getting taller. As more people migrated to urban areas, developers saw the need to go higher. But with this comes its own unique set of challenges. How can the safety of ground floor be transferred to, in the most extreme case, level 163? Grooved mechanical pipe joining solutions When it comes to high-rise buildings, there are a number of potential challenges for a piping engineer To find out how grooved mechanical pipe joining solutions are helping developers & engineers go higher, we spoke to Matthew Strohm, Director of Product Development (Piping System Design) at Victaulic. When it comes to high-rise buildings, there are a number of potential challenges that a piping engineer will need to take into consideration, most of which relate to thermal movement and the resulting forces on the building. Other issues such as seismic activity and building creep (the natural movement of a building due to settlement) also need to be taken into account. Compensating for thermal expansion and contraction Specifically related to piping systems and subsequently, pipe joining solutions, is the unique problem of having to compensate for thermal expansion and contraction, while at the same time, accommodating for higher pressure. Change in pipe diameter is not an uncommon concern for engineers, however, providing a solution which could operate at a pressure gauge of 25 bars, or the fluctuating temperature of water, presents its own challenges. It’s with these issues in mind that engineers choose their joining solutions, which is why these are the very criteria we set our Victaulic pipe joining solutions against. Grooved vs. Traditional Pipe Joining For decades, the traditional solutions for joining pipes have been welding, threading or flanging. These are good solutions to choose from, but there is a distinct lack of flexibility in a solution that fuses or flanges system components together. This is where flexible grooved couplings come in. They are solutions that allow controlled linear and angular movement at each joint to accommodate not only for thermal expansion and contraction, but also building sway and creep. So how do flexible grooved couplings manage this? It’s essentially down to the design of their components. The dimensions of the pipe coupling housing key is narrower than the pipe groove, allowing room for movement. Furthermore, the width of the pipe coupling housing allows for pipe end separation, which in turn allows the grooved pipe joint to accommodate movement. Benefits of Grooved couplings There are many benefits of grooved couplings, with space-saving being a key advantage on projects, both large and small There are many benefits of grooved couplings, with space-saving being a key advantage on projects, both large and small. As many project managers and engineers know, saving on space can be the key to unlocking extra value above initial planning. Additionally, grooved couplings are perfectly placed to accommodate for piping movement, whereas welded joints that in their very nature are designed to be fixed in place, need to have an area of space to allow for a welded expansion loop or alternatively, enough space to allow the star-pattern tightening of a flanged flex connector. Saving time, money and labor Besides the savings on space, grooved connections offer contractors savings in three key areas: time, money and labor. The installation-ready design of Victaulic’s grooved couplings allow for an easier installation, meaning a process which might take 30 minutes through a welded solution for instance, can now take just five minutes. As any contractor will testify to, this is valuable time that can be used for other parts of the project. With a reduction in time comes savings in cost and labor. Naturally, less labor is used for the same job and in the case of grooved couplings, less skilled labor is required (in comparison to the high skill level needed for welded joints). It’s these aspects that will ultimately deliver contractors with valuable project savings. Grooved connections offer savings in three key areas: time, money and labor Mechanical riser solutions There are 3 ways to accommodate for thermal movement within risers using a grooved mechanical system: The first method is called top of riser free-floating method and involves installing rigid couplings on the riser and two flexible couplings on the horizontal adjacent piping at the top of the riser, which can reduce the need for riser clamps or other structural during installation and allows the system to move freely within the design tolerances. The second method involves working with grooved expansion loops that help to save up as much as 2/3rd of the size of welded U-shaped expansion loops and avoids forced welded pipe deflection. While welded expansion loops require eight welded joints to assemble, the forces exerted on the joint are far greater than those applied on a grooved expansion loop, and generate greater stress, which ultimately requires larger anchors and guides in order to direct the movement. The third method is working with grooved expansion joints instead of traditional in-line expansion joints, which typically have wear parts and manufacturer-recommended maintenance cycles of five years, which also poses problems due to riser accessibility once the construction is complete. Grooved expansion joints like the Victaulic Style 155 are maintenance-free for the life of the system. Importance of anchors In a system using only flexible joints, risers are installed with anchors at the top and bottom and the piping guided every other length to prevent angular deflection at the joints within the piping run. Anchors distribute the movement forces across the structure and also provide the important task of directing pipe movement. At the pipe anchor location, there will be no differential movement between the piping and the building structure, which forces the pipe to thermally expand or contract from that location. This allows the design engineer to control how and where the movement in a system occurs and to provide the best solution to accommodate that movement. A10 Grooved Riser Anchors upgraded A good manufacturer will always listen to customer demand, especially in an evolving market A good manufacturer will always listen to customer demand, especially in an evolving market. Off the back of strong feedback from contractors, Victaulic recently upgraded its A10 Grooved Riser Anchors to a standard product. With the primary functions of carrying the weights and forces that act downward to the base of the riser and connecting the riser to the rest of the structure, the anchor has been providing sturdy support for some of the tallest buildings around the world. Future trends for high-rise buildings One trend already taking place, and I expect to continue, is contractors bringing riser experts into the project at an earlier stage. It just seems to make logistical sense to operate in this fashion. it’s a more efficient use of time to collaborate early in the process. I believe contractors and engineers will seek assistance from companies such as us to help design blueprints together, working in tandem to produce the right solution. Vertical buildings are on the rise. For generations, people have been moving to urban areas, putting greater demand on housing residents and employees. Through the use of grooved coupling solutions as an alternative to traditional methods, contractors can benefit from greater flexibility, reliability, ease of installation and ultimately and most importantly, speed of the installation process.

Air conditioning has become a huge part of our lives whether we know it or not. Most offices have them so that members of staff can enjoy a regulated working environment without having to shiver or overheat. This often makes the office a nice place to work in and helps staff to stay productive throughout the day, regardless of what is going on with the weather. Commercial air conditioning is something that we often take for granted because we barely realize that it’s there. The only time that we notice it is when it breaks down or it doesn’t function as efficiently as we want it to. Why is it important to regularly maintain an HVAC unit? When an AC unit isn’t looked after in the right way, there can be a number of things that can either go wrong Air conditioning maintenance is something that so many people overlook. This can be for a whole host of reasons, including whether it’s that they are unaware that it needs regular maintenance or they think it’s too costly to take on. These are often the most common reasons that air conditioning units aren’t looked after properly. When an air conditioner unit isn’t looked after in the right way, there can be a number of things that can either go wrong and disable air conditioning or just hinder its ability to do its job. Temperatures With a well looked after, fully functioning commercial air conditioner, you’ll find that the temperatures are very accurate and work as intended. This means that everything within your unit is in top condition and working well. For example, on a hot day, when you set your thermostat to a low temperature, you’ll get exactly that.  Over time you may find that your air conditioning starts to struggle a little. This can be in a few different forms. You may detect that it takes a lot longer for your air conditioning to get up or down to the right temperature. This can be for a whole host of reasons and so keeping it regularly maintained will help to reduce this risk. Cost-effective As mentioned, a poorly maintained air conditioning unit will likely mean that it takes longer to get to the right temperatures or it may not be efficient enough to even reach the temperature you’re after. With that in mind, it can start to cost a lot more to run your HVAC system in this state. Due to the fact that it might take longer to reach your preferred temperature, you could end up paying more as time goes on. If you don’t rectify this problem, you may end up with an air conditioning unit that no longer works enough to be worth running. This will have adverse effects on the working environment and your members of staff. Safety of staff Depending on where you are in the world, heatstroke is also a very dangerous problem One of the biggest concerns for a business owner, the HR department and the individuals themselves, is that the office needs to be suitable to work in. From a health and safety standpoint, employees need to be safe and protected. Often air conditioning maintenance falls under this and is a necessity. Depending on where you are in the world, heatstroke is also a very dangerous problem. Having an inefficient air conditioning unit that can’t keep up with the rising temperatures could potentially put your employees at risk! The same also goes for those in more densely populated cities like London, New York City and even France. The air quality in and around these cities can be awful and so having air conditioning to clean and filter the air before it arrives in your office can make a big difference. Preventative maintenance Preventative maintenance is possibly one of the most important parts of owning any sort of machinery. Whether we’re talking about a car or air conditioning, preventative maintenance is a must. Preventative maintenance is just the act of regular maintenance throughout the lifetime of a product. It often involves changing of parts or fluids, even if they don’t need it in that instant. For example, if you take your car for a service and the engine oil is still sort of okay but will need replacing in 2 months’ time, would you just leave it or get it changed there and then? This type of preventative maintenance is designed to make sure that everything is in top condition and works perfectly all of the time. The biggest problem we face is that people think preventative maintenance isn’t necessary and while, yes your AC system will run without it, it’s likely to cost you so much more in the long run and could end up upsetting your staff too with a drop in temperatures. Employee satisfaction Commercial air conditioning is still a huge part of employee satisfaction Although at the time of writing this, many people are working from home, commercial air conditioning is still a huge part of employee satisfaction. Having an operating office, warehouse, school or indeed home, with air conditioning can help to keep people happy throughout the year. As a business owner, HR or general manager, it’s part of your job to keep employees happy and working in an optimal environment. Without this, employees may start to get fed up with attending an office that’s way too hot to work in. Importance of a regular maintenance plan A regular maintenance plan is going to help you keep your air conditioning system in the best state possible. You‘ll be able to detect faults and malfunctions before they have a direct impact on your commercial air conditioning system and prevent any further damage. Through the utilization of a proper plan, you should find that your system has a longer lifespan than those that don’t and should work more efficiently saving you time, money and the hassle of a broken system. Keeping your staff members happy is also a must and so dedicating some of your budget to air conditioning maintenance might just help you to keep morale and employee satisfaction on the right level.

HVAC systems have never received more widespread attention and media coverage than they have this year. As researchers determined that air transmission was a major factor in the spread of COVID-19, HVAC systems quickly became an area of intense discussion. Much of the news coverage from outlets like the New York Times, NPR, CNBC, or USA Today focused on air filtration. HEPA and MERV have become acronyms that people recognize, and UV Light and Plasma Ionization air purifiers have almost become dinner table topics. The need for discussion and debate about these topics is evident. As we look to resume some resemblance of normal life we need to feel safe sharing spaces with other people. Commercial HVAC Systems At the forefront of all of these discussions regarding air purification, is the massively flawed assumption that we must recirculate a large amount of the air from space to save energy. Most commercial HVAC systems only utilize 20% fresh air. That means that 80% of the air you are breathing in a public space has been on this ride before. The underlying principle here, from a thermodynamic perspective, is sound. I just spent a lot of energy (and $) conditioning this air for human comfort and now you want me to just throw it away?! In the name of all things public health, yes, throw it away! Energy Consumption It takes a large amount of energy to cool, dehumidify, and/or heat air so we humans can enjoy our time indoors in comfort Now before you draft your eloquently worded hate mail, let me take a minute to explain why we think you can just throw away perfectly conditioned air and still maintain a high level of energy consciousness. It’s true that it takes a large amount of energy to cool, dehumidify, and/or heat air so we humans can enjoy our time indoors in comfort. However, it is possible to exhaust ALL of the contaminated air from an occupied space and still conserve a large portion of the energy in that air. This can be done by passing the outside air (fresh air) and the exhaust air through separate heat exchangers where the energy can be transferred without the two air streams physically making contact. From a hygiene perspective, this process is ideal. Hospitals and industrial plants have been using one form or another of this technique for decades. The challenge for wider, commercial, adoption has been packaging restrictions of these systems and in a lot of cases the energy consumption of your supposedly energy-saving equipment. Energy Recovery Technology Cue ACT’s award-winning energy recovery technology, the Pump-Assisted Split Loop Energy Recovery Heat Exchanger. This product recently won the AHR Expo 2021 Innovation Award in the highly competitive Green Building category. The magic of the technology relies on the efficiency of the boiling and condensation process. When harnessed properly, one can exchange huge amounts of energy between two air streams just by circulating a particular fluid from one system to the next. A major benefit of allowing the fluid to boil and condense around the loop is that it allows the system to operate passively, using just the forces of good old fashion gravity. As a fluid boil, a portion of the liquid is converted into vapor which naturally wants to rise. Once that vapor gives off its energy it condenses back into a liquid that naturally wants to fall. If you can provide a source of energy input for boiling and a source of energy removal for condensing you can create a naturally circulating loop that requires absolutely zero electrical energy to operate. Two Separated Air Streams Transferring energy between two separated air streams with the least amount of total energy consumption and no cross-contamination In commercial HVAC systems, the warmer air stream can be the source of energy input and the cooler air stream can be the source of energy removal. As the seasons change, the air that is exhausted from a space flips from being warmer than the outside air (in the winter for instance) to be the colder air stream (in the summer). This means that at some point during the year you lose your gravitational advantage so for the other half of the year when you need to transfer energy in the opposite direction of gravity, ACT’s system uses a fractional horsepower pump (hence the pump-assisted part). The end result is a method of transferring large amounts of energy between two separated air streams with the least amount of total energy consumption, and with no cross-contamination. And because the fluid is circulated between the two air streams (either by gravity or by way of a small pump) this technology is highly geometrically flexible and customizable. With this product, HVAC systems can take in 100% fresh, outside air and throw it all away without having to worry about being wasteful. Improving HVAC Systems Most of the focus and efforts around improving HVAC systems have so far been centered too much on how we make old technology deal with new problems. These kinds of approaches are band-aids, at best, and often result is short-sighted solutions that never really advance the industry as a whole. ACT’s new product helps solve the problems of the new normal while moving the HVAC industry closer to that breath of fresh air we could all use right now.

Attitudes about indoor air quality need to change, especially given the current pandemic that forces people to spend most of their time indoors. But addressing the pandemic through increased ventilation and better indoor air quality can be expensive. For example, the Los Angeles Unified School District, the second-largest in the nation, has spent $6 million on HVAC upgrades and new air filters in response to the pandemic and expects to pay about $1.7 million a month for ongoing inspections and filter replacements. Updating & Improving HVAC Systems Updating HVAC systems to minimize virus spread has been an expensive proposition all around. Some school districts in California report the costs are insurmountable. Sometimes seeking to replace or update an HVAC system opens a can of worms: Electrical systems must be rewired, asbestos must be removed, and/or an expensive roof needs to be replaced. Schools in low-income areas are especially likely to be in poor condition, and unable to afford improvements. Some school districts have used money from the federal CARES Act – a $2 trillion federal economic package passed in March – to make ventilation improvements. Hope remains that additional state and/or federal money will be available, but funding is still likely to be inadequate. Airborne Transmission Study showed that some classrooms had air change rates below 0.5 changes per hour The airborne transmission was initially underplayed as a means of spreading the novel coronavirus. There was more emphasis on the dangers of touch during the early days of the pandemic. However, the airborne (aerosol) spread is now believed to make up about 75% of transmissions. A group of 239 scientists from around the world advocated more action to address aerosol spread in a July 2020 open letter to the World Health Organization (WHO). The concern is a global challenge. For example, a survey of 20 classrooms in the United Kingdom, carried out by National Air Quality Testing Services (NAQTS), revealed very low air change rates that could increase the risk of virus transmission. The study showed that some classrooms had air change rates below 0.5 changes per hour (3 to 5 changes per hour would be desirable). Even small increases in flow rate could reduce the risk of infection significantly. Raising airflows from zero to 100 cu m/hour cuts the risk by up to a third, according to NAQTS. Fresh Air Ventilation & Filtration The Scientific Advisory Group for Emergencies (SAGE) advised the UK Government last fall of a need to ensure undisrupted education for children of all ages. A critical part of keeping children in school is clear guidance and support packages, including better ventilation and air filtration, particularly through winter. The German government advises schools to open their windows for at least five minutes every hour Other countries can learn a lot about the value of opening windows to allow in more fresh air from the Germans. For years, Germans have habitually opened their windows twice a day, even in winter. In fact, “lüften,” or airing a room, is among the cheapest and most effective ways of decreasing the spread of the coronavirus. The German government advises schools to open their windows for at least five minutes every hour; for example, when classes are changing. Improving Indoor Air Quality Airing of rooms is a likely factor in the lower number of coronavirus cases reported in Germany compared to, say, the United Kingdom. In the end, improving indoor air quality involves some combination of letting in more fresh air, upgrading air filtration systems, and installing technologies such as UV light to kill pathogens. However, implementing these measures only mitigates the likelihood of contracting COVID-19. Some risk remains.

During the coronavirus pandemic, UV-C systems have surged from a niche market to mass production capable of meeting historic demand levels. As a result, UV lamp manufacturers, as well as their component providers (e.g., glass suppliers), have struggled to meet the growing demand. Because of UV-C’s historic proven effectiveness, interest in and orders for UV disinfection equipment have increased exponentially during the COVID-19 pandemic. For example, in July, lighting manufacturer Signify (previously Philips Lighting), reported increasing “UV-C light source production capacity by a factor of eight.” The pandemic has settled in the affirmative the question of whether 254 nm germicidal wavelength can inactivate the genetic material in the SARS-CoV-2 virus (that causes COVID-19). acute respiratory syndrome Moreover, when aerosolized, the COVID-19-causing virus is likely to be more susceptible to UV-C damage than other coronaviruses such as SARS-CoV-1 (that led to the 2003 severe acute respiratory syndrome) or MERS-CoV (that caused the 2012 Middle East respiratory syndrome). Delivering doses of SARS-CoV-2 virus vaccine is one of the greatest logistical challenges ever undertaken The Centers for Disease Control and Prevention (CDC) and ASHRAE [American Society of Heating, Refrigerating and Air-Conditioning Engineers] have recommended UV-C as a technology that can “reduce the risk of dissemination of infectious aerosols in buildings and transportation environments.” The need for the technology continues. Delivering billions of doses of the SARS-CoV-2 virus vaccine is one of the greatest logistical challenges ever undertaken. airstream disinfection As of this writing, experts do not agree on the number of vaccinated individuals necessary to outright extinguish the COVID-19 pandemic. “As there is no clear end in sight, there is no foreseeable decline in the demand for the germ-killing and airstream disinfection benefits offered by UV-C,” says Daniel Jones, President, UV Resources, a pioneering company in ultraviolet-C (UV-C) equipment. Specifiers and HVAC contractors should not be deterred from recommending and specifying the proven benefits of UV-C disinfection systems, Jones contends, as the industry is rapidly adapting to what might likely be the “new normal” level of demand. “In other words, we expect commercial and residential demand for UV solutions to remain high due to their ability to efficiently inactivate the SARS-CoV-2 virus,” he says. pharmaceutical processing plants The company reports that disease-defeating UV-C surface and airstream technologies are especially popular with facility managers servicing hospitals and nursing homes, commercial offices, as well as food and pharmaceutical processing plants. Upper-room UV-C fixtures have been a "go-to" technology in the battle against the spread of COVID-19, among restaurants, school and university classrooms, airport screening areas, correctional facilities and community shelters. COVID-19 pandemic has ingrained the need for ongoing infection mitigation systems" Even after the pandemic subsides, demand for UV solutions will continue to remain high as perception of the technology has shifted to a health and safety need, says Jones. “Although the current pace of demand for germicidal UV-C solutions may decrease, the COVID-19 pandemic has forever raised awareness and ingrained the need for ongoing infection mitigation systems,” he comments. indoor air quality Despite nearly eight decades of research and thousands of applications in hospital emergency and operating rooms, urgent-care centers, universities, and first-responder locations, UV-C has previously not been widely leveraged. During the 1990s and 2000s, drug-resistant “superbugs” and hospital-acquired infections renewed interest in UV-C, known to kill virtually any microorganism, including antibiotic-resistant germs. The current pandemic, however, has laid bare the societal health outcomes offered by the proven germ-killing technology. While antibacterial UV-C applications have improved indoor air quality for decades, it was the pandemic that took the technology’s use in the eyes of building managers from energy savings to infection mitigation. air conveyance systems HVAC systems operate better, longer and users are happier when UV-C is installed in air conveyance systems Now, the market is starting to view UV-C along the same lines as air filtration - providing a cleaner, healthier environment which will result in a decrease in absenteeism. Additionally, HVAC systems operate better, longer and users are happier when UV-C is installed in air conveyance systems. Higher demand has produced supply challenges for these products. How can HVAC engineers best navigate equipment/parts supply shortages? Facility engineers and HVAC contractors would be well advised to place orders as early as possible and to accept partial-order shipments, says Jones. This will ensure that HVAC firms have the components/fixtures in-house (or even installed) once the lamps finally arrive. Jones advises specifying engineers who are unfamiliar with UV-C and who are conducting their due diligence should investigate the following points when choosing a supplier: Market Longevity - There are only a handful of companies that have been selling UV-C for HVAC/R for years. EPA Registration - Examine a device manufacturer’s registration with the US Environmental Protection Agency (EPA) as a pesticide device-producing establishment. Industry Credentials - Make sure products meet applicable safety standards and certifications (such as UL/CUL and CSA). Industry Participation - Look for manufacturers that routinely author technical articles, actively serve on regulatory and standards committees, and enjoy a solid industry reputation. surface disinfection system Selection of an air or surface disinfection system is based entirely on the application. UV Resources furnishes the following chart that summarizes the selection factors:

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.

Hawkes Place is a property like no other. Situated in Sevenoaks, Kent, one homeowner has created a truly unique building where every room is connected through home automation devices. Designed and built by Tony Gotts as a personal project, the three-bedroom, one-storey property was the first smart home he had built. The unique design sees each room completely curved, with no square corners in sight. With the entire house automated, including audio, lighting, heating, blinds, and front door access, the property has been built to a high standard to create a truly remarkable home. Controlled entrance system To support the installation, Mr. Gotts called upon the experience of the electrical contractor, Luke Kavanagh of Lake Home, who suggested one single supplier cover all of the home’s automation needs. To transform his property into a smart home, the owner wanted to connect the heating, lighting, blinds, and audio, while also incorporating a controlled entrance system. In addition, each room of the house required its own touch screen control system. Hawkes Place was the first property with which the owner had utilized home automation systems to this extent, and therefore an easy-to-use all-encompassing system was required. Door entry system Every room in the property had at least one element of smart technology installed Electrical contractor, Luke Kavanagh, recommended Legrand’s User Interface range, including its MyHOME Up system, coupled with its Bticino door entry and Nuvo audio systems. “As soon as I understood the brief, I immediately recommended the Legrand suite of smart home products,” Luke comments. “I contacted Chris Janes at Legrand, who drove out to Kent to discuss the different options with the homeowner in person. This was really useful as it enabled the owner to see exactly what was possible for the size of the property.” Every room in the property had at least one element of smart technology installed. Throughout the house, the heating, lights – both inside and outdoor – and blinds are all controlled by the MyHOME Up system, providing the end-user with full control at all times. The accessibility of the house was also enhanced, thanks to the use of a Bticino door entry system. Audio distribution system Additionally, the Legrand Nuvo multi-zone audio distribution system was installed throughout the property. Allowing audio to be managed and controlled in numerous rooms, users can connect music and audio streaming services and play in all areas of the home. For this project, one major advantage is the ability to bring together control of door access, as well as the lighting, heating, and blinds, on mobile phone apps. In addition to this, 7-inch touch screen panels were installed into every room, allowing complete control. For the installer, Legrand’s MyHOME Up system served two key benefits: its ease of installation and the functionality for the end-user. Once connected to the BUS system and the app is installed, the devices will set-up automatically. Intense training courses The app allows the installer to easily access multiple devices when starting up the system Luke comments: “Coming from an electrical background, the simplicity of Legrand’s systems means we are able to support project managers transform properties into smart homes. I don’t have expertise in IT, and I find that other similar systems require technical knowledge in order to complete the installation, which often includes expensive and intense training courses.” One of the key benefits of a MyHOME Up installation is that the innovative app supports the connection of all devices and is easy to control for both the installer and end-user. The app allows the installer to easily access multiple devices when starting up the system, thanks to the self-learning procedure, while the user can then manage their home automation scenes at any time. Confidently creating scenes Luke continues: “The whole installation process was very easy, not just from my point of view but the end user’s as well. The customer has gone from being a smart home novice to confidently creating scenes which improve day-to-day living habits. Since the installation was completed, we have already successfully recommended the system on another three projects.” In addition to installation and account support, Legrand also offers free training courses. The MyHOME Up range can be installed after just one day’s training, and installer Luke Kavanagh utilized this free service before installing the system. Luke adds: “I had previously undertaken a number of Legrand’s training sessions, including a session in Belgium, as well as for MyHOME Up. It is a really good program, and makes the system incredibly easy to install for anyone in the profession.” Creating smart scenes YouGov’s Smart Homes 2018 Report indicated that almost one-quarter of Britons own one or more smart home devices The course explains the role of smart devices in the home, and shows how creating smart scenes and actions can help end-users decrease their energy usage and waste. Free to attend, the training program is ideal for contractors and system integrators and takes place at Legrand’s state-of-the-art training center in Birmingham. Home automation is not new. In fact, YouGov’s Smart Homes 2018 Report indicated that almost one-quarter of Britons own one or more smart home devices, excluding smart meters, while one in ten have two or more. High customer satisfaction While adoption is becoming more common, electrical installers and contractors are tasked with the challenge of understanding this often-complex technology, to enable them to enhance their services to customers. Taking advantage of training from manufacturers, like Legrand, can make the installation much easier, while also providing high customer satisfaction. Luke Kavanagh concludes: “This project is an excellent example of how a simple, slick and extremely efficient home automation system can be installed. The Legrand products are very easy to install and the customers are always left smiling, testing new combinations each day. While not all systems are the same, I would recommend taking advantage of any available training because it not only equips you with the ability to install effortlessly, but it also provides the knowledge to answer any customer questions.”

Thermo King® customer Bottomley Enterprises greens up the holidays for millions of people across the United States each year. For many people, the holidays are simply not complete without a traditional tree, wreath, garland, swag, or some type of tabletop greenery – the fresh evergreen smells are often that final touch that make gatherings with family and friends memorable. And while millions flock to their local box stores for these holiday treasures, the odds are good that the products originated from the Blue Ridge Mountains and were delivered with love by Thermo King Customer Bottomley Enterprises. Producing exceptional quality “Our farm ships to large box retailers, the who’s who of retailers,” said Ken Kaelin, president of Bottomley Enterprises, the transportation arm for Bottomley Evergreens and Farms, which has been producing exceptional quality and service for nearly 30 years. What started out as a small family farming business in the hills of North Carolina has grown to produce a large variety of vegetables – think cabbage, corn, cilantro, collards, sweetcorn, pumpkins, green beans, and more, that feed consumers throughout the U.S. It also became one of the largest suppliers of holiday greenery in the eastern United States. The farming business led to the creation of Bottomley Enterprises in 2004 as founder Mitchell Bottomley fulfilled his dream of owning his own trucking company. While the businesses operate separately, Bottomley Enterprises still hauls the farm’s products. Home-Grown products Bottomley has depended on Thermo King refrigeration units to preserve the quality of the home-grown products From its beginning, Bottomley Enterprises has depended on Thermo King refrigeration units to preserve the quality of the home-grown products it transports. “The company started with just a couple tractors and trailers. Today, we are running a fleet of 70 tractors and 120 refrigerated trailers – all with Thermo King Precedent® S-600 units and a few legacy units that are used at the farm,” said Ken. “That number represents 40 percent growth within the past 15 months alone. Our trucking arm has enjoyed fast growth through our great culture, solid customer base and dedicated employees who understand that service is everything. All of this has really allowed for an exciting evolution for our companies.” Remote setting control Indeed, service is king for the Bottomley businesses, “And that’s a big reason why we have always chosen Thermo King to protect our products,” said Mitchell, who owns the company with his mother, Martha. “We are proud Thermo King users – it’s the only unit we have because we can depend on them. We love our Thermo King units.” The company not only depends on the refrigeration capacity of the units but also the telematics technology built into each unit. “We count on the TracKing® telematics,” said Ken. “The scrutiny of food safety and the ability to have visibility throughout the supply chain is like quenching a thirst for shippers. It helps us keep insurance and liability costs down. It offers remote setting control. It helps us track each load. It’s essential these days.” Keeping products safe Thermo King Central Carolinas also takes care of our reefer service work" Beyond the product is the service Bottomley receives from its home dealer Thermo King Central Carolinas and the entire Thermo King dealer network. “The partnership we get from Ben Cox, our service representative, is outstanding – he really is an extension of our employee team. He helps us manage our equipment and maintenance needs, and he provides our drivers with the product and operational information they need to run the unit efficiently – and keep our products safe.” “Thermo King Central Carolinas also takes care of our reefer service work, ensuring the equipment is tuned up and ready to go – this is wildly helpful to us. And if service is needed when our 120 team drivers are out on the road, we have an entire network to call on – that is added peace of mind,” said Ken. Refrigerated transport business Peace of mind is particularly important this time of year, when so many are depending on a fresh selection of trees and greenery at their local stores so they can decorate their homes with traditional holiday décor. The Bottomley family is poised to continue delivering for the long haul having recently opened a 33,000 square foot new trucking terminal in Mount Airy, North Carolina, that will accommodate many years of growth and create new jobs. “They have built a legacy – in both their farming business and the long-haul refrigerated transport business, and it truly is a pleasure to partner with them and see their continued successful growth,” said Ben.

Tunnel ventilation systems are essential to the infrastructure of tunnels, which serve to connect people around Japan. Panasonic's solution is driven by a complex network of jet fans, electrostatic precipitators that clean the air, large exhaust fans, ventilation towers, and silencers. Together these components ventilate vehicle emissions, limit noise, and ensure a safe exit in case of fire. When driving through tunnels, they've probably seen what looks like a jet engine hanging from the ceiling. These are in fact jet fans, which help direct airflow to an extensive exhaust network. Sensors monitor conditions in tunnels and help save energy while cleaning the air for release. Silencers are used because the exhaust fans are incredibly loud. Tunnel ventilation solutions Safety is paramount as the large jet fans are installed in the tunnel ceilings above cars, thus Panasonic is vigilant in the manufacturing and installation process to ensure no errors. The ability to offer a one-stop solution is one of Panasonic's strengths. As an industry that began in 1964, Panasonic has years of experience, and its people feel an obligation to protect it and the responsibility to evolve it. Infrastructure advances such as Panasonic's comprehensive tunnel ventilation solutions are a major contribution to society. They provide clean air to the community and a safe driving environment, helping drivers feel confident as they cruise through Japan's tunnels.
