Few data centers live in a world of ‘high’ density, a number that is a moving target, but many are moving to high[er] density environments. Owners of higher density data centers often aren’t aware of how many variables factor into cooling their equipment. The result is that they spend too much on shotgun solutions that waste capacity when they would be better served by taking a rifle shot approach. This means understanding the heat dispersion characteristics of each piece of eq...

Hinwil, June 7, 2021, 07:00 a.m. - Due to continuous high customer demand, the Belimo Group expects a substantial increase in sales and profitability for the first half-year of 2021 compared to the previous year period. However, the outlook for the full financial year 2021 remains uncertain. In the first few months of 2021, Belimo recorded consistently high demand in all three market regions. Thus, the Group expects a sales increase of around 10 percent in the first half of 2021 compared to the previous year period. Semiannual Report Due to the gratifying sales development in combination with still reduced travel and marketing expenses and an improved financial result, the result for the first half of 2021 is set to be substantially higher than that achieved in the same period of the previous year. In particular, the COVID-19 pandemic has had an adverse impact on the second quarter of 2020. As a result, comparing figures with the same period of the previous year is of limited use. However, Belimo expects sales growth also in comparison with the first semester of 2019. The Semiannual Report will be published on July 22, 2021.
As part of its new Sustainability Strategy and its ambition to enable a low-carbon society, ABB has committed to partner with its customers and suppliers to reduce their emissions and to achieve carbon neutrality in its own operations by 2030. Ahead of World Environment Day on June 5, ABB announced that it has joined three initiatives led by the international non-profit Climate Group in line with its action plan and focus areas identified to reduce its own emissions: EV 100: ABB commits to electrifying its fleet of more than 10,000 vehicles by 2030. ABB in Sweden, for example, has already started to convert its around 700 company cars to all-electric vehicles, while ABB in the UK announced last year that the company will be transitioning its over 500 company cars to an all-electric fleet by 2025. RE 100: ABB commits to sourcing 100 percent renewable electricity until 2030. In 2020, 32 percent, of all the electricity used by ABB, was either purchased as certified green electricity or generated by the company’s own solar power plants. Since 2020, ABB in Switzerland already sources 100 percent of its power from renewable sources. EP 100: ABB commits to establishing energy efficiency targets and continue deploying energy management systems at the company’s sites. Already today, more than 100 ABB sites are covered by externally certified or self-declared energy management systems. Science Based Targets initiative Furthermore, the company’s own reduction targets have now also received approval by the Science Based Targets initiative (SBTi) confirming that they are in line with the 1.5°C scenario of the Paris Agreement. The SBTi is a partnership between non-governmental organizations CDP, United Nations Global Compact (UNGC), World Resources Institute (WRI) and the World Wide Fund for Nature (WWF). The SBTi defines and promotes best practices in science-based target setting and independently assesses companies’ targets. We believe that the combination of technology and empowered people is key to reducing emissions" ABB has also joined the Business Ambition for 1.5°C Campaign, a global coalition of UN agencies, business and pioneers, led by the UNGC. low-carbon society “At ABB, we want to lead by example across our own operations and the confirmation that our ambitious targets are now scientifically verified is an important milestone for the company,” said Theodor Swedjemark, Chief Communications and Sustainability Officer. “We believe that the combination of technology and empowered people is key to reducing emissions and avoiding the further heating of our planet.” ABB’s Sustainability Strategy has a clear focus on areas with the biggest impact – enabling a low-carbon society by reducing emissions, preserving resources, and promoting social progress underpinned by a strong commitment to integrity and transparency. As part of the strategy and starting in 2021, ABB has also added specific targets related to sustainability into its senior management remuneration.

With ongoing efforts from governments across the globe to reduce carbon emissions and with an ever greater focus on sustainability, it is vital that the HVAC sector does its part in becoming more environmentally conscious. And, while there have been steps to become more sustainable, there is a huge amount that still needs to be done to make sure that many of the targets that have been set are attainable. In buildings, both large and small, industrial heating accounts for roughly two thirds of industrial energy demand and around a fifth of global energy consumption. Figures like this show the need to have efficient and environmentally-friendly HVAC equipment in place to make the crucial steps towards reducing the contributions these systems make to our carbon footprint. High energy consumption in construction sector A 2019 report by The International Environment Agency (IEA) showed that the buildings and construction sectors combined were responsible for over 30% of global energy consumption and nearly 40% of carbon emissions. This is indicative of the steps the sector needs to take to play its role in a more eco-friendly society, some of which are already underway. However, much more needs to be done if the UK is to reach its goal of reaching net zero carbon emissions by 2050. As we envisage what a post-COVID world might look like, businesses and governments are continuing to put sustainability and lower carbon emissions at the forefront of their planning and the HVAC sector is certainly no exception. But with change in the sector a daunting prospect, decision-makers often don’t know where to start. Smart Technology use in HVAC systems Smart HVAC uses sensors that integrate with a building’s automation system With the constant growth and greater deployment of smart technologies within the HVAC sector, this is certainly a way that systems can become more efficient. Smart HVAC uses sensors that integrate with a building’s automation system. These sensors then collect information about conditions throughout the building. Heat waves are now a far more common occurrence in the United Kingdom. The Met Office estimates they are up to 30 times more likely and will be a bi-annual occurrence by 2050. It is important that any uptake in HVAC usage doesn’t lead to a drastic increase in emission generation. This is one of the areas where smart systems will become crucial. Many scientists have been unequivocal in their sentiment that heat waves are a cause of greater emissions and expect temperature records in the UK and Europe to be broken more regularly, so sites will need to be equipped to handle these conditions. Regulating temperature with hand-held devices With wireless systems now much more commonplace, temperatures can be controlled easily from hand-held devices. With these new technologies, those managing the systems can also benefit from remote monitoring and maintenance, reducing the need to travel to the site for yet another environmental incentive. To accompany the smart systems, equipment including smart thermostats can be installed to maximize HVAC efficiency. Other smart systems available to businesses include smart furnaces and air conditioning units that are far easier to operate than their traditional counterparts. Reducing unnecessary ventilation While global temperatures continue to rise, air conditioning usage has increased and has contributed to greater levels of energy usage. A huge amount of needless emissions are generated by unnecessary ventilation, contributing heavily to heat loss and overall energy wastage. Recirculation of air is a traditionally lower energy cost method of retaining heat and keeping emissions low, however, we must be mindful of the risks associated with recirculating air. The risk of circulating diseases is negated somewhat with heat recovery ventilation, which both removes the risk of disease spreading and improves energy consumption. Efficiency performance of new AC units Air conditioning units in particular contribute significantly to a building’s energy consumption Air conditioning units in particular contribute significantly to a building’s energy consumption, equating to 10% of the UK’s electricity consumption and as such it is important that we bear in mind ways to counteract the emissions this creates. Global energy demand for air conditioning units is expected to triple by 2050, as temperatures continue to rise year on year. The efficiency performance of new air conditioning units will be the key, when it comes to ensuring that escalating demand does not equate to greater emissions. Another issue for suppliers and manufacturers to address is differing rates of consumption for AC units in different countries, with units sold in Japan and the EU typically more efficient than those found in China and the US. Modularization Modular HVACs have also become increasingly popular in recent years. Modular HVACs are responsible for heating, cooling and distributing air through an entire building, with their increase in popularity largely down to their greater levels of energy efficiency, cost effectiveness, flexibility and substantial ease of installation and maintenance. Modular HVACs can be tailored specifically for workspaces and they often allow work to be done on the systems without disturbing the workforce, achieved primarily through rooftop placement. Commercial workspaces are larger and often require differing needs to residential properties and can cater to a wide range of the specific requirements of work and commercial spaces. As we strive for lower carbon emissions, it seems that this trend will continue and will become a key area in reducing emissions that HVACs have traditionally generated. System maintenance and training To meet government and industry requirements, many new buildings will require HVAC systems that can be maintained simply in order to perform in a more energy efficient way. Many companies are looking at ways to become climate neutral and significantly reduce their footprint Many companies are looking at ways to become climate neutral and significantly reduce their footprint. Companies are following the likes of German-based company, Wilo Group, who have announced they are committing to sustainable manufacturing by developing a new carbon neutral plant and HQ in the next few years. Lowering carbon footprint As we continue to move towards an ever more environmentally conscious society, it will be of paramount importance for companies, governments and the public to think about ways in which we can lower carbon emissions. Smart technologies will certainly be at the forefront of this, negating many needless journeys and making it easier for industries to adjust settings and tackle issues remotely. Greater levels of training will help equip us with the tools to make sure we are best placed to reduce emissions and be more sustainable as a result. While the steps outlined above do show some progress and measures we can take, there is far more that we can do as a sector to significantly reduce HVAC’s carbon footprint and once we have moved beyond the impact of the COVID-19 pandemic, this will surely be at the front of industry leader minds.
As we continue to grapple with COVID two very clear future objectives have emerged: The need for safer and healthier indoor environments to protect against SARS-CoV-2 and other infectious microbial. Acceleration of UK’s net zero by 2050 plan - 78% reduction by 2035 compared to 1990 levels. Last week a group of world-renowned scientists published a paper entitled ‘A paradigm shift to combat indoor respiratory infection’ affirming the need for improved building ventilation systems to deliver better more effective control of the indoor infectious transmission. This paper proposes increased ventilation rates and the distribution of‘ clean disinfected air’ and the use of ‘ultraviolet devices while avoiding unproven technologies.’ Energy efficiency improvements According to UK GBC, the built environment contributes 40% of the UK’s total carbon footprint Whilst we can all agree with the end game objective it must be noted that ventilation air change increases, which is the primary COVID mitigation, are likely to significantly increase the UK’s carbon emissions when we go back to work. Boris Johnson’s government announced on 20 April 2021 its plans to reduce carbon emissions by 78% by 2035. According to UK GBC, the built environment contributes 40% of the UK’s total carbon footprint and approx 80% of 2050 buildings have already been built. Further, according to the Local Government Association, in order to achieve Net Zero by 2050 close to 28 million buildings will need retrofit energy efficiency improvements which will, in turn, need retrofit ventilation improvements to avoid consequential IAQ and health problems. Quite clearly, the challenge of decarburization of energy and heating and ventilation improvement is in existing property stock space and it is quite simply enormous - at least 1 million per year. Ventilation improvement strategies We have been focused on making buildings more energy-efficient for years by specifying or retrofitting improved insulation characteristics but in many cases, this has resulted in under ventilation and created consequential issues of IAQ and related health problems especially in naturally ventilated buildings which are the predominant strategy for domestic properties. This has created an increased demand for retrofit ventilation improvement strategies such as PIV and since the pandemic and the revelation that the primary transmission route is airborne, this demand has increased further. This has created an increased demand for retrofit ventilation improvement strategies such as PIV Official guidance states the primary mitigation is increased fresh air ventilation air changes with any mechanical recirculation processes turned down significantly or off altogether. At its heart is the logic that increased ventilation air changes beyond current levels will blow the virus away combined with turned off recirculation processes reducing the ability for the virus to spread thus resulting in an overall reduction of the risk of transmission. Increased ventilation rates Whilst fundamentally sound there are a number of consequential issues that must be recognized: Ventilation is a dilution/displacement process. It does not destroy viral emissions, it just blows live emissions around so the risk of transmission can arguably be increased if people are downstream. There are various academic studies that affirm this view such as the University of Oklahoma. Ventilation also provides no protection to surface contaminations. Increased fresh air ventilation rates make buildings significantly less energy efficient. Windows must be opened and left open for naturally ventilated spaces and mechanical systems must be turned up and all heat recovery processes turned off. This also makes buildings colder during colder months which affects occupant comfort, health, and productivity. Increased ventilation rates increase outdoor pollution ingress which can create similar consequential problems of IAQ and cause health problems or worse as the recent ruling by the Coroner in the case of Ella Adoo-Kissi-Debrah shows, whose tragic death was caused by an asthma attack brought on by air pollution. Mechanical HVAC systems This is not surprising considering one of the benefits of HVAC recirculation is heat recovery Evidence from various UK corporates whose buildings incorporate ducted mechanical HVAC systems has shown that energy consumption across their estates whilst following official guidance has not just increased but has skyrocketed especially over the winter months. This is not surprising considering one of the benefits of HVAC recirculation is heat recovery. All of this heat recovery benefit is lost when following the official guidance. Similarly, domestic homeowners and tenants especially whose properties are naturally ventilated would have seen increases in energy costs over the winter if leaving doors and windows open (although many would have chosen not to open windows when they know it will increase costs and make the property colder). Evidence, therefore, shows that from an energy efficiency and carbon footprint perspective we have been going backwards since the pandemic hit which begs the question. How is it going to be possible to meet the 2050 carbon reduction targets? Air disinfection molecules Just as we improved energy efficiency through insulation but created IAQ and health problems we are now improving (apparently) infection control at the expense of energy efficiency. What is needed is a strategy that delivers one AND the other not one at the expense of the other. A strategy that will effectively reduce the risk of infectious transmission in our indoor spaces without penalizing energy efficiency. A strategy that will effectively reduce the risk of infectious transmission in our indoor spaces Active air purification that creates a safe-to-breathe equilibrium concentration of natural air disinfection molecules throughout the indoor space offers a credible, realistic, safe, and affordable solution and is just as easily retrofitted as it is applied to new build. Photohydroionization or PHI is a tried, tested, and proven technology that achieves instant and continuous ‘point of transmission’ elimination of infectious microbials whether in the air or on surfaces. Ingress outdoor pollution PHI also instantly treats any ingress outdoor pollution such as particulates as well as indoor originated pollution such as odors, VOCs and allergens (pet dander, dust mite fecal matter). Developed and patented over 20 years ago in the US with over 5 million installations in over 60 countries around the world, PHI is designed for quick and easy retrofit into new and existing buildings, either integrated into any HVAC supply infrastructure or installed standalone on walls or ceilings. PHI is probably the most scrutinized of all air purification technologies having been subjected to numerous safety and efficacy tests by nationally accredited labs and testing bodies over 2 decades as well as in real-world customer settings such as Lloyds of London. Its SARS-CoV-2 performance credentials are peerless with no equivalent in public health and academic settings, showing 4+ log continuous reductions over a 24 hour period against nebulized emissions every 15 mins throughout a 1,280 ft3 chamber. Ionized hydroperoxide molecules PHI works by mimicking Earth’s atmospheric air cleaning processes indoors PHI works by mimicking Earth’s atmospheric air cleaning processes indoors. It produces an equilibrium concentration of ionized hydroperoxide molecules in similar concentrations to the outside air - 0.01-0.04ppm so is perfectly safe to breathe. These molecules are throughout the indoor environment which breaks down and destroys infectious microbials and other organics such as VOCs, odors, gases on contact before reverting back to harmless water vapor and oxygen afterward. Most importantly PHI is not reliant on air movement to blow the live virus away or toward passive technologies like filters or UV so it does not penalize building energy efficiency. Indeed, PHI allows the continued safe use of HVAC recirculation processes because the equilibrium effect effectively disables the ability for any virus to transmit. PHI is also not behavior dependent and is constantly working in the background regardless of there actions or behaviors of building occupants. In other words, it provides a unique extra layer of protection to building occupants beyond the current mitigations. Improved indoor protections Given the fact that PHI equilibrium can achieve strategic and continuous protections throughout indoor spaces without relying on ventilation air change increases beyond current levels, it could be regarded as a more realistic strategy to achieve the objectives of improved indoor protections against infectious microbials and the 2050 carbon emission reduction targets. PHI could be quickly and easily retrofitted into all existing buildings and indoor spaces Further, PHI could be quickly and easily retrofitted into all existing buildings and indoor spaces and specified for all new builds going forward, thus achieving rapid transformation to safer and healthier indoor environments. Buildings with mechanical HVAC strategies that were meeting the requirements of Part F entering the pandemic i.e. almost every commercial building will not need ventilation air change increases for the purposes of infectious transmission control after PHI has been retrofitted. Naturally ventilated buildings Those that were not should be subject to an HVAC performance audit by a suitably qualified HVAC professional who would recommend improvements or a change to a new strategy. The UK’s 2050 energy efficiency targets will be best served if all of the UK’s approaching 28 million naturally ventilated buildings are retrofitted with energy efficient mechanical ventilation performance improvements. Positive Input Ventilation (PIV) is the go to strategy for these retrofits. Unlike centralized Mechanical Ventilation with Heat Recovery (MVHR), PIV was originally conceived as an affordable retrofit strategy to solve condensation and mold problems without having to open windows. It is quick and easy to install and is one of the most common whole house strategies in the UK with millions of public and private sector installations dating back to the 1980s. Mechanical ventilation performance It will simultaneously improve IAQ helping to create the healthiest indoor environments It delivers predictable and reliable mechanical ventilation performance at virtually no electricity cost, it increases ventilation air change rates without the need to open windows and it offers important energy efficiency benefits - energy recovery from solar gain amounting to approx 500kW per year according to Energy Saving Trust for lofted properties and optimized floor to ceiling heat distribution through destratification which optimizes thermostat controlled energy consumption. To summarize, PHI’s tried, tested, and proven ‘point of transmission’ treatment of viruses and microbials will create the safest indoor environments it is possible to create without penalizing the enormous energy efficiency gains made over recent years which are now being eroded. It will simultaneously improve IAQ helping to create the healthiest indoor environments paving the way for improved health, wellbeing, and productivity at home and in the workplace across our society.
The education field was faced with multiple challenges this past year. Not only did the COVID-19 pandemic bring the necessity of online learning, but it has also brought up necessary changes to physical schools and universities, when reopening time arrives. The health and safety of students, staff, and faculty has become a priority for directors of school operations, who have been working to properly adapt school facilities to this new reality we are facing. Ensuring health and safety of students Besides safety measures like the addition of hand sanitizers, reinforcing the use of masks and social distancing, these professionals were faced with an even bigger and more important issue: ventilation and airflow indoors. School facilities have many unique features that increase the concerns regarding indoor air quality. Occupants are usually very close together, considering that school buildings have four times as many occupants as office buildings for the same amount of floor space (EPA). Variety of pollutant sources According to the WHO, the virus can also spread in poorly ventilated and/or crowded indoor settings Other issues include tight budgets, the presence of a variety of pollutant sources (including specialty classrooms, like art, gyms, and labs), concentrated diesel exhaust exposure due to school buses in the property, and a large amount of heating and ventilation systems that may cause an added strain on maintenance staff. On top of that, schools usually have to worry about child safety issues, concerned parents, and wellbeing of faculty and staff. According to the World Health Organization (WHO), the virus can also spread in poorly ventilated and/or crowded indoor settings, where people tend to spend longer periods of time and aerosols particles tend to be suspended in the air, which leads to the importance of indoor air quality in classrooms. Importance of natural ventilation and HVAC systems Natural ventilation and HVAC systems are the basic methods to bring clean air indoors, however, schools that rely only on these methods of ventilation need to be aware of their potential limitations. HVAC systems, for example, should have regular maintenance checks and filter changes, in cases where the system is less sophisticated, schools need to add new forms of air purification to effectively mitigate airborne pathogens. Studies showing quality of air in US schools Studies have shown that low-standards HVAC ventilation systems may contribute to airborne diseases transmission due to low air exchanges rates, poor maintenance and lack of high-efficiency filters. For this reason, portable air cleaners are becoming more and more popular to create a healthy learning environment. EnviroKlenz, an indoor air quality company, conducted real-life setting studies to show the quality of the air in schools in different areas of the United States. The study measured the amount of particulate matter in classrooms, with and without the use of additional portable filtration systems, which allowed for comparison and analysis of the benefits a portable air cleaner can provide. National EPA standards for indoor particulate matter The study also compared the current data to the national EPA standards for indoor particulate matter (PM), in order to evaluate the performance of the EnviroKlenz Air System Plus. The IAQ meters focused on PM1, which is about 1 micrometer in size (70 times smaller than the diameter of human hair!). The systems ran in operational educational environments, with daily schedules being carried out as usual and results can be seen below. School directors of operations also must pay attention to the different technologies available in portable air cleaners. With the growth of the industry, new emerging technologies have come up, and there’s still lack of third-party testing to prove their efficacy. Other technologies, like carbon filters, do not work against airborne pathogens and may release harmful byproducts back into the environment. EnviroKlenz Air System Plus EnviroKlenz Air System Plus, which utilizes a patented earth mineral technology to capture pathogens, is at 99.9% efficiency The EnviroKlenz Air System Plus, which utilizes a patented earth mineral technology to capture virus, bacteria and other harmful pathogens, is at 99.9% efficiency and is complemented by a medical-grade HEPA filter and UV-C lights, was also tested against a carbon-based air cleaner in a classroom. As shown below, the carbon system struggled to keep consistency, with peaks and valleys throughout the day. Meanwhile, when the EnviroKlenz Air System Plus was turned on, the PM1 levels were steadily low for over 4 consecutive days. Deploying portable air cleaners in classrooms Adding a portable air cleaner to classrooms and common areas will increase air exchange rate and mitigation efforts, but the long-term benefits go beyond the pandemic. Studies have shown that good indoor air and ventilation rates are directly linked with students’ academic achievements and can increase performance. High CO2 levels in a school environment are also associated with lower average annual attendance and worse individual test performance. Other long-term benefits include reducing symptoms of those who suffer from respiratory diseases and creating a favorable environment not only for students, but also for teachers and staff; while bringing a sense of comfort and well-being to parents and the community. Combined benefits of air filtration, ventilation, and purification “When we’re operating more normally, maybe we’ll be able to cut down on some of the traditional flu-peaks that schools have, or cold peaks, that kids just bring into school, by managing the airborne virus and bacteria quality,” said Peter Twadell, Head of School at Birches School in the US, and an EnviroKlenz Customer. School officials need to consider the combined benefits offered by filtration, ventilation, and purification methods to create the healthiest environment possible. Thinking in a pandemic-conscious mindset, air quality has gained the recognition it deserves in creating a proper and healthy learning environment.
Artificial Intelligence (AI) is an emerging tool for a long list of applications, including the ability to analyze and ensure optimum performance of an HVAC system. Emerson’s Sensi Predict smart HVAC solution is an example of how AI can boost the capabilities of HVAC. It has been recognized with a Silver Edison Award in the Innovative Services – AI category. Sensi Predict smart HVAC solution Sensi Predict combines inputs from 10 sensors in an HVAC system and analyzes the performance of heating and cooling systems in real time. Intelligent monitoring alerts home owners and their contractors, when HVAC systems are not operating at full efficiency. The alerts, which can be accessed on a smartphone, can predict and prevent problems, ensure corrective maintenance, lower utility costs, and prolong the life of an HVAC system. Fault detection and diagnostics are a new frontier in HVAC technology, delivering a seamless and simple user experience. Sensi Predict HVAC system configuration Here is how the Sensi Predict system is configured: Sensors monitor the temperature of the air flowing from the HVAC system into the home, and also the return air temperature, coming from the home back into the system. Sensors also monitor temperatures in the liquid and vapor lines in the refrigerant loop, and the indoor and outdoor control lines, communicating back and forth from the thermostat to the outdoor unit. Other sensors monitor the current draw and indoor voltage of indoor units, and current and voltage to the outdoor units. Data from the sensors is used to analyze how well the HVAC is operating, including detailed monthly performance checks, with results issued to the home owner and the contractor. If a warning is detected, an alert will be sent in real time. 24/7 monitoring The 24/7 monitoring is summarized in a personalized home owner portal and monthly performance reports The 24/7 monitoring is summarized in a personalized home owner portal and monthly performance reports that include any alerts, loss of performance, runtime and estimated cost and filter status. Actionable alerts tell when a problem is detected, sent via an email with a straightforward explanation and recommended action. “Our heating and cooling systems are critical to the health and comfort of our families and the environment, yet we have little visibility into how they perform on a day-to-day basis,” said Jamie Froedge, Executive President of Emerson’s Commercial and Residential Solutions business. The Sensi Predict systems seek to provide additional visibility. Sharing real-time system insights The Edison Awards highlight top-tier new product innovation, service development and human-centered design. Named after inventor, Thomas Alva Edison, the awards recognize and honor global innovation. The award to Emerson’s Sensi Predict system recognizes it as a 21st-century solution to the maintenance of home heating, ventilation and air conditioning systems, sharing real-time system insights, in order to help home owners monitor performance and prevent unexpected problems. Maximize system lifetime and minimize energy costs “We are honored to be recognized for this innovative technology that provides both awareness and peace of mind, when it comes to an essential component of the home,” said Jamie Froedge. Sensi Predict also provides benefits related to installation, by validating a quality install and eliminating call backs. Over time, it maximizes system lifetime and minimizes energy costs. service and maintenance information In terms of maintenance, the system provides information to ensure that all contractor truck rolls generate revenue and decrease the average time on site. The 24/7 monitoring limits home visits to only when needed and increases transparency to the customer of suggested repairs and upgrades. Home owners can access the Sensi Predict Homeowner Portal on the official website for detailed information, based on real-time data about how their system is functioning and its performance history, energy usages and costs and predicted maintenance needs.
The term ‘robotics’ refers to technology or machines that substitute or replicate human actions. ‘Human augmentation’ is another term, referring to the use of technology to reduce strain and fatigue as workers perform strenuous tasks over long periods of time. Hilti Group has introduced robots and semi-automated technologies to the construction trades, including HVAC. The role of these technologies in the HVAC market is to increase efficiency and accuracy, reduce costs, and decrease physical strain/injury of HVAC installers on the jobsite. Two Hilti products, Jaibot and the EXO-O1 exoskeleton, can make workers’ lives better by reducing risk on the jobsite, increasing productivity, and improving the quality and consistency of work. Reducing worker fatigue Jaibot is a semi-autonomous mobile, overhead drilling robot. It executes its tasks based on building information modeling (BIM) data. The robot is a cordless and easy-to-use system that does not require expert skills. It locates itself accurately indoors, drills the holes while controlling dust, and finally marks them according to trade. Jaibot provides faster, safer and more accurate execution of digitally coordinated mechanical, electrical and plumbing (MEP) systems on the jobsite. Jaibot performs the ceiling drilling and marking, thus allowing the workforce to focus on installation Jaibot is designed to work with workers, not replace them, by taking on strenuous and repetitive tasks that have been shown to put workers’ health at risk. Guided by a trained operator, Jaibot performs the ceiling drilling and marking, thus allowing the workforce to focus on installation. This makes jobsite teams faster, more productive, reduces worker fatigue and enables them to deliver a constant plannable output, according to Hilti. Required drilling information “One of the few pitfalls the BIM process encounters is getting the digitally coordinated and designed project from the office and out onto the job site,” says Aidan Maguire, Business Unit Manager for Hilti North America’s Measuring, Layout and Robotics technologies. “While traditional methods will take the BIM model and print out paper or utilize 2D blueprints to use to install anchors, the Jaibot works directly from the coordinated digital design or BIM model using a point cloud of the anchor locations. Jaibot can also read the required drilling information such as drilling diameter, drilling depth, trade or system from the BIM model. This allows the semi-autonomous Jaibot to operate directly from the most up-to-date digital model.” The Hilti EXO-O1 is a wearable human augmentation system designed to reduce fatigue and strain. The exoskeleton is designed for workers performing strenuous overhead tasks for long periods of time. Performing overhead work Long-term, the EXO-O1 contributes to prevention of musculoskeletal disorders This system will allow its user to perform the overhead installation of HVAC systems while reducing the injuries and errors that come with the normal fatigue common from this type of work. Hilti’s research shows that users who perform overhead work for more than 60% of their time benefit from up to 47% reduction of load on their shoulders. With decreasing strain and fatigue, the EXO-O1 allows users to remain productive while working safer for longer periods. Long-term, the EXO-O1 contributes to prevention of musculoskeletal disorders. The upfront costs of these systems are designed to be competitive when compared to traditional methods, says Maguire. “The other benefits of the systems such as rework, injuries, and labor costs, while increasing productivity and accuracy all provide extensive and sometimes immeasurable benefits for the systems’ operators,” Maguire adds. Human augmentation systems Human augmentation systems help overcome labor shortages in the HVAC trade in several ways. They are not designed to replace workers but rather to augment the workforce by taking over strenuous and repetitive tasks that have been shown to put workers’ health at risk. The augmentation systems help to reduce absentee days, fill gaps caused by a diminishing qualified workforce, and allow the workforce to focus on more value-adding tasks, thus contributing to higher and more consistent outputs. These systems help construction companies retain the tenured workforce already in place These systems help construction companies retain the tenured workforce already in place and attract new talent to the industry by offering more attractive working conditions and the opportunity to work with state-of-the-art technologies. The cost of a robotic system like Jaibot can be directly compared to other methods of overhead drilling all the way down to a per-point cost. Quicker project delivery These systems have a direct impact on the time and labor required to complete these tasks and can provide value through supplementing the requirement for skilled labor, reducing labor cost, and providing time savings on the critical path of a project to enable quicker project delivery and potentially meeting targeted schedule bonuses. Additionally, while these technologies are relatively new to the construction industry, as the utilization of these systems increases there will be the opportunity to study and quantify the health and safety savings over time. Both the Hilti Jaibot and EXO-O1 exoskeleton are new innovations currently being rolled out across the United States. “As with all innovations, it is often not the technology that drives adoption, but human beings,” says Maguire. Adopting new technologies The key to overcoming this mindset is to closely support the first adopters of this technology" “While we see a clear advantage of deploying mobile robotic or human augmentation solutions for certain tasks and observe an increase in activity in the market, it is hard to predict how long this will take. We envisage that significant progress will be made over the next five years. As the construction industry continues to move towards digitalization, more and more companies will look for technology that gives them an advantage over their competitors, and Jaibot and EXO-O1 will help them do exactly that.” The biggest obstacle for greater deployment is the construction industries’ resistance to change, says Maguire. The phrase ‘because this is how we’ve always done it’ is prevalent in construction. Many construction companies are risk-adverse and prefer to continue to utilize the tried-and-tested methods of the past. “The key to overcoming this mindset is to closely support the first adopters of this technology in order to quantify and provide proof of the many benefits of adopting these new technologies and methods,” says Maguire.
What do customers want from their HVAC company? It’s a challenging question, and the answers reveal a path to a more successful and customer-centric company. There are numerous articles written that offer consumers advice on choosing an HVAC company. In the simplest terms, wouldn’t it be possible to ‘reverse engineer’ that advice to provide a roadmap to guide HVAC companies in how to succeed? Addressing consumer concerns Often, consumers’ concerns surround whether a company is a reputable and/or a well-managed business. Answering questions about basic requirements, such as insurance should be easy. Another element of consumer-oriented advice on choosing an HVAC company is to find one that is qualified to do the job. For example, able to work on the specific type of equipment a consumer has, whether central air conditioning, humidifiers, heating sources, or whatever. From the perspective of the HVAC contractor, this advice points to a need for constant training and updating of skills related to various equipment types. Seeking HVAC specialists Customers may be looking for specialty service, specific to a certain type of equipment or type of installation Consumers are also advised to seek out specialists in the work they need doing, whether a repair, a new installation or related to a specific type of equipment. Contractors must both understand their own strengths and weaknesses and be able to communicate them clearly to put customers at ease. Consumers will also be looking for contractors, who are experienced in repairing the brand or type of system they have. Customers may be looking for specialty service, specific to a certain type of equipment or type of installation. Contractors should constantly evaluate their skills-sets, their strengths and weaknesses, and provide full transparency to enable customers to make the most informed decisions. Better to walk away from a job than to overextend or misrepresent a contractor’s skillset. Such overreach never ends well and can damage a contractor’s broader reputation. HVAC contractors come in all sizes Customers will also be looking to evaluate the size and stability of the HVAC company that they work with. HVAC contractors come in all sizes, of course, and the size of a company does not necessarily reflect on the quality of work. However, stability and a good reputation are essential, especially for a smaller company or one-man shop. Consumers are often advised to ask for references, especially if dealing with a smaller contractor. HVAC businesses can be proactive in this regard by keeping references handy and even collecting customer testimonials to share with prospective customers. Positive reviews a key indicator Online reviews, hopefully all positive, are another element that can help to put prospective customers’ minds at ease. Ideally, if an HVAC contractor is doing a good job, positive reviews, testimonials and references will happen organically. Consumers are often advised to ask for certifications to document an installer’s skillset, so keeping up with the related paperwork will ensure that a customer is comfortable with any contractor’s skill level. Specific HVAC contractor license requirements Specific contractor license requirements vary by state and even at the local level Specific contractor license requirements vary by state and even at the local level. Required license numbers should be displayed on websites and promotional materials, and most states have an online directory listing of licensed contractors. Be attentive to other requirements, too, such as the special EPA certifications required to use refrigerant. Consumers expect their HVAC contractors to guide their buying decision, whether determining the correct size HVAC unit to serve a specific home size, analyzing flow rates, or recommending systems to meet specific needs. Striking a balance between simplicity and technical detail Delivering on these expectations requires a delicate balance between simplicity and technical detail. The customer needs to be comfortable that the installer knows his stuff but does not want to be overwhelmed by arcane technical discussions or puzzling acronyms. Best by far is to keep it simple (and be willing to provide additional detail – described in layman’s terms – if the customer has questions). Membership in local trade associations can provide additional credibility to a contractor, and provide additional sales and networking opportunities, too. Importance of warranties Warranties are another critical issue for consumers. Everyone offers manufacturers’ warranties, but there is an opportunity for HVAC contractors to offer even more, whether an extended warranty, inclusion of labor, as well as parts, work guarantee on repairs, and/or an extended maintenance contract. Availability 24/7 could enable a contractor to take work away from a competitor Customers should be warned that maintenance or repairs performed by an unqualified company may void the manufacturer warranty. Availability in an emergency or on short notice is another way HVAC companies can differentiate themselves among consumers. Availability 24/7 could enable a contractor to take work away from a competitor who is closed for the weekend. Emphasizing on customer services Customer service also requires a personal touch, so an ability to communicate well with potential customers can generate extra business. Emphasize listening skills and make sure customers know they are being heard. In all dealings with customers, be straightforward and honest in order to build long-term trust. To grow a successful HVAC business, prepare proactively to answer the questions customers are most likely to ask.
The YMCA Association of Greater Rochester, New York, is one of the oldest associations in the United States. They currently have fifteen thriving locations built over the last century that range in size from 50,000 to more than 70,000 square feet. While the size and age of the facilities vary, high standards for energy efficiency and indoor air quality (IAQ) are key objectives in the design, construction, and operation of these buildings. "Good indoor air quality is very important" notes Eastside Family YMCA Executive Director Kevin Fitzpatrick. "Our members are quick to note if there is a problem." Indoor air pollution Indoor air quality is a constant challenge at a fitness center. Pollutants are present everywhere. In some respects, the effects of indoor air pollution are heightened in fitness centers because occupants are breathing heavily during workouts and inhaling more air through their mouths; this air forgoes the filters in the nose and travels deeper into the lungs. There is also a risk of mold growth and odor from sweaty garments and towels in the locker room There is also a risk of mold growth and odor from sweaty garments and towels in the locker room, or from moist air emanating from a swimming area. The work to mitigate the odors and air quality hazards associated with any fitness center requires diligence and careful planning. For example, the Eastside Family YMCA, the newest and largest branch in the Rochester Association, opens as early as 5:00 am and closes at 10:30 pm on weekdays. Healthy indoor environment After hours, cleaning crews work to refresh the space while ventilation operates 24/7 to keep the facility fresh and odor free. Even before the day-to-day upkeep of a facility, the managers of these modern fitness centers proactively specified HVAC solutions at the construction or renovation phases to ensure a clean and healthy environment. Exhausting contaminated air and continually replacing it with fresh outside air is an effective method of maintaining a healthy indoor environment. The drawback to high ventilation rates is increased heating and cooling costs to replace the exhausted air. Facilities can marginalize these increased costs, however, by utilizing an energy recovery ventilation (ERV) solution that can reduce outdoor air energy costs up to 80%. Outdoor energy challenges Airxchange wheels have proven reliable in multiple buildings over a number of years" All branches of the Rochester YMCA Association use ERV systems to overcome the outdoor energy challenges presented by Rochester's cold winters and hot, humid summers. According to Christopher Marks, Vice President of Properties, the association leadership team prefers Airxchange for all new installations because of their excellent reliability. "Airxchange wheels have proven reliable in multiple buildings over a number of years. We will specify Airxchange wheels in all buildings that utilize an ERV." Including ERVs in their buildings during construction or renovation allows the HVAC system designers to specify smaller and more efficient heating and cooling units, reducing the upfront cost and enabling the high ventilation rates that provide clean, healthy air. Unitary rooftop system The Eastside facility is an award winning building, recognized by the national YMCA as a ‘Top Ten’ building in the USA. At that facility, the Child Watch, gym, locker rooms and community spaces are all ventilated using energy recovery wheels as part of the commercial unitary rooftop system. "In the eight years since this HVAC system was installed, there have been no maintenance issues, and system reliability has been excellent," adds Fitzpatrick. The robust energy recovery performance of the Airxchange wheels also resulted in them being specified for an upcoming addition to the facility. When the addition is completed, the facility will be a total of 105,000 sq. ft., making it the largest branch in the region. Gas heat exchangers LaBella Associates chose to pretreat incoming outside air with energy recovery According to the principal engineers who designed the addition to the Eastside YMCA, Kathleen VanderZwaag and Casey Bernhard of LaBella Associates, because of the many energy savings measures used on the project, including energy recovery, the facility was awarded rebates from the New York State Energy Research and Development Authority (NYSERDA) that assisted in reducing the up-front costs of the new space. They also note that Labella uses ERVs in any building where repurposing the energy in exhaust air allows them to reduce the size of the heating and cooling units. At the Eastside YMCA, LaBella Associates chose to pretreat incoming outside air with energy recovery in order to raise the temperature of the air on a winter design day, reducing the load of the gas heat exchangers. Enhancing patron experience LaBella has had great success with Airxchange over the last decade and continues to specify their products on new projects in the region. The fresh, clean air that enhances the patron experience is the result of the attention to air quality by the entire Rochester YMCA Association. These buildings are bright, airy, and inviting family destination. The proactive approach to building design and maintenance offers a fine example for any fitness center.

A large manufacturer of steel cables from Detroit, Michigan contacted Wattco with a problem that the cables they manufactured were corroding in their warehouse and needed a solution to prevent this from happening. Steel products that often sat in inventory for long periods of time were more prone to corrosion. Traditionally, light lubricating oil was used to coat the cables, preventing rust from settling in. The cables were exposed to a steam heating tank, containing light oil at ninety-five degrees Fahrenheit. The problem was that the oil had a lower than average viscosity and tended to disappear after a period of time. Oil immersion heaters Oil that has a higher viscosity can solve this problem. It would coat the cables and offer a longer storage life than before Oil that has a higher viscosity can solve this problem. It would coat the cables and offer a longer storage life than before. The trick was to heat it up to 220F, and make the oil more viscous without sacrificing the quality of the cables. Wattco provided 12 immersion heaters, each with 9KW 480V 3PH that had control panels and a redundancy system that prevented downtime. Thermocouples for heater safety Two thermocouples were used – one for temperature control and the other for high limit shutoff to safeguard the heaters. The heaters were also overrated to provide the customer additional power available. 120,000 LBS of cable was able to be treated with oil reaching 210 degrees temperature. Wattco suggested a high limit setting of 275 degrees to avoid overheating. This was easily programmed in the digital temperature controllers. Once we installed the new system, the process was monitored for 6 months and found no additional signs of corrosion. Benefits include: No maintenance costs on process heaters Safety temperature controller that prevents overheating Cables are fully protected from corrosion Electric industrial heaters are fairly inexpensive and last for years

AET Flexible Space has completed a Cat-B fit-out of underfloor air conditioning equipment on the second floor of 8 Waterloo Place for the new incoming tenant, a leading wealth management company. The Edwardian building with a grade II listed Portland Stone façade was fully refurbished in 2008, creating 3,000 sq. m of prime office space in the St James’ area of London, with the second floor becoming the first space to be occupied. CAM-C direct expansion system The system at 8 Waterloo Place is a CAM-C Direct Expansion system with underfloor supply air and underfloor return air, specified by consultant Watkins Payne Partnership after both the client and architect requested no ceiling-based services to allow the decorative plasterwork and featured cornices to be exposed. The AET Flexible Space CAM-C direct expansion system fits this brief perfectly. The Cat-A works were completed in August 2017 and the building was subsequently shortlisted for the 2017 BREEAM Awards, Refurbishment category. Energy efficiency The CAM-C downflow unit supplies conditioned air into the plenum thereby serving as the ventilation zone The CAM-C downflow unit supplies conditioned air into the plenum beneath the raised access floor, which serves as the ventilation zone. This zone is divided into supply and returns air paths using an airtight relocatable baffle and then the CAM receives spent air back at floor level for re-conditioning, allowing the total elimination of services located in the ceiling. Conditioned air is fed into the space using modular, plug and play TU4 Fantile units with the upgraded EC fan option for additional energy efficiency. Additional cooling requirements Working with Sale Service and Maintenance on behalf of the fit-out project lead, Overbury, AET supplied additional fan terminals, return air grilles, and underfloor air segregation baffle to accommodate the additional cooling requirements and cater to the new workspace layouts. The client also opted to install sound attenuator boxes beneath the grilles to minimize noise transfer between the open plan workspace, meeting rooms, and Director’s offices. Remote management User control of the underfloor air conditioning system is enhanced by the addition of fourteen wall-mounted Flextouch controllers, permitting remote temperature and fan speed adjustment of the Fantiles without having to physically access the integrated controller within the unit. The fit-out works reached practical completion and the final result is a fabulous high specification, modern workspace.
AET Flexible Space has completed a major upgrade of the underfloor air conditioning system at a historic building located in the Clerkenwell area of London, The Bond Works building at 77-79 Farringdon Road. The building was originally constructed in 1882 as the London premises of Lincolnshire-based engineering firm, Marshall & Sons, and previously underwent a full redevelopment in 2007 by a group of private investors. The eight-story building is located on a prominent corner position, with floor-to-ceiling glazing ensuring that each floor benefits from optimum natural light. The exposed brick and ironwork grants a contemporary warehouse-style finish to the six extensively refurbished floors. Underfloor air conditioning Underfloor air conditioning was specified and installed for the height-restricted building in 2007, along with other energy-saving design features such as nighttime ice storage. As part of the recent works, AET Flexible Space was successful in its bid to upgrade the existing downflow unit controls and replace all fan terminals on the six refurbished floors with AET Fantiles. Integrated controlling systems With underfloor air conditioning systems, fully conditioned air is fed into the plenum by zonal downflow units (CAM), which are then supplied into the workspace via fan terminal units (Fantile). The Fantile units feature integrated controllers where users can personally adjust fan speed and temperature The Fantile units feature integrated controllers where users can personally adjust fan speed and temperature to suit their own comfort. Systems can be configured with underfloor or high-level return and can easily integrate with passive or other ventilation systems. The existing system at Farringdon Road is the equivalent to an AET CAM-V system, supplying conditioned air via the floor plenum and receiving spent, used air back at a high level for re-conditioning. Upgraded the existing units Working for Twenty1 Construction and new building owners, NFU Mutual, AET engineers upgraded the existing units with AET control boards, associated cabling, new actuators, and filters. 140 TU4-AC Fantiles were supplied for the six floors of speculative Cat-A accommodation with the capacity to add additional terminals for tenant fit-out. The final result is a spectacular, contemporary “cutting edge meets heritage” workspace, blending historic features with new modern services in the heart of the Clerkenwell business district.
