The last 18 months have seen an acceleration in digitalization across many aspects of work and home life. Home spaces have become workspaces, and commercial buildings have had to adapt to changed use and lower occupancy rates. Coupled with this, there is a growing need to dramatically reduce carbon emissions from buildings - according to the International Energy Agency (IEA), the buildings and construction sectors combined are responsible for over 30 percent of global energy consumption, and nearly 40 percent of carbon emissions. Installing separate systems This means that demand for a smarter approach to heating, ventilation and air conditioning (HVAC) management is crucial for building managers, who need to ensure that their properties can adapt to changed use, respond to the wellbeing of their occupants, and run efficiently to keep emissions as low as possible. Armed with this data, facility managers can take proactive steps to improve usage Of course, architects and developers have been installing separate systems to control HVAC for decades which have given building managers greater control and access to different areas of a site. However, with digitalization comes the addition of web-based platforms to allow these verticals to integrate seamlessly with each other, providing data on how efficiently and effectively a building operates through a single view application. Armed with this data, facility managers can take proactive steps to improve usage, which will see properties proactively react to the environmental and personal needs of their occupants. Centrally controlled lighting Many commercial buildings will already have a certain element of smart technology installed – from centrally controlled lighting and HVAC systems to remote management of security and energy management systems. However, it is often the case that these multiple applications are managed in silo. This means facilities managers don’t have a consolidated view of their data. In addition, not all managers will be using the data these devices produce to take steps to reduce the carbon footprint of their properties. Embracing smart technology – and a central control platform - gives building managers access to instant data on how their HVAC assets are performing in one place. This insight can be used to gain a thorough understanding of how the different systems in the building interact, and the external factors that may impact them. Effective building controls By using this data, operators can implement effective building controls to manage efficiencies By using this data, operators can implement effective building controls to manage efficiencies, identify maintenance issues, ensure the wellbeing of occupants, and inform future investment priorities. So, for example, if a building is now being used in a different way due to changed occupancy, the data will show the manager what needs to be done to ensure it is operating as efficiently as possible. We know that there will be increased demand for more flexible spaces as companies move towards remote or hybrid working models. It is likely that we will visit our offices less for day-to-day work and use them more as hubs to meet and collaborate. The ability to turn a traditional ‘bricks and mortar’ building into an agile asset that can learn and adapt to its surroundings will become increasingly important. Smart HVAC management Smart offices will become independently intelligent, learning how occupants use the space and services, adjusting lighting, HVAC and other systems to maximize health and comfort. Smart HVAC management will create a trend for ‘healthier’ buildings that will have a positive impact in terms of improved quality of life and wellbeing of occupants, ultimately resulting in higher productivity levels. In short, there has never been a better time to adopt smart HVAC technologies. Intelligent buildings that would have been unimaginable a few decades ago are now a reality. As buildings become smarter, they can learn how occupants use the space and services and proactively adjust lighting, HVAC and other systems to improve use, cut emissions and reduce energy consumption.
As 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.
The air quality of our indoor spaces has seen renewed interest in the past 18-months as a strong relationship emerges between the quality or flow of air and the spread of coronavirus. In the rush to get workers back into their physical workplaces, we have seen a surge of office buildings improving and reconfiguring their HVAC systems to better protect employees from COVID, even monitoring systems that provide building occupants a real-time view of air quality throughout the building. Better air quality has not only become beneficial for workplaces during the pandemic, however, there are also many other reasons to improve HVAC systems. COVID has simply made better air quality necessary for companies, rather than a nice-to-have. Honeywell Survey 60% said they are more likely to invest in indoor air quality optimization technology A June survey by Honeywell questioned 1,554 facility managers around the world on the impact of COVID-19, with 75% confirming that the pandemic has caused them to permanently rethink how their buildings operate. Within the results, nearly 60% said they are more likely to invest in indoor air quality optimization technology. Another study compiled by 39 scientists from 14 countries and published in the journal ‘Science’ has demanded universal recognition that infections can be prevented by improving air ventilation systems in buildings. While a survey of 436 human resources managers in the US, conducted by Pollfish on behalf of Omni CleanAir, found that nearly every business surveyed took steps to improve air quality during the pandemic. Pollfish Omni CleanAir Survey The Pollfish – Omni CleanAir survey found that 73% of surveyed organizations had upgraded existing HVAC systems to support improved filtration, namely the introduction of MERV13 filtration, while 63% reported the installation of medical-grade filtration such as HEPA into their central HVAC systems. A further half of respondents said their organizations had introduced portable HEPA filtration machines, while 42% had deployed ultraviolet germicidal irradiation (UVGI) and 38% had deployed air ionization technologies. After years of relatively minimal improvements to air quality in workplaces, the pandemic has driven buildings to follow official guidance on best practices for clean air. Combining Filters and Air Cleaners According to ASHRAE, using combinations of filters and air cleaners that achieve MERV 13 or better levels of performance for air recirculated by HVAC systems is a core recommendation for reducing exposure to airborne infectious diseases. Meanwhile, public health information during the pandemic has made a clear distinction between the rate of transmission between indoor and outdoor air-quality environments. This has prompted commercial building designers to bring more of the outdoor air into the building through ventilation systems and new architectural design approaches. Authority Comment “Dozens of the world’s top experts in how diseases spread have called for big improvements to the air in buildings and there is now a recognition by the WHO and the CDC that coronavirus can spread through the air. However, cleaner air won’t just fight the COVID pandemic, it will also minimize the risk of catching flu and other respiratory infections that cost the US alone more than $50 billion a year,” said Phillip Dowds, the founder and director of OKTO. “Businesses are annually being hit with the costs associated with sick leave and loss of productivity due to poor air quality and ventilation systems, viruses, flu symptoms, asthma, chest infections, etc.” Varying Air Quality Conditions Workplace air quality is not just about reducing sickness eitherVarious studies have long proven a link between air quality and absenteeism. A 2002 study by Milton DK. et al., compared employee absenteeism in offices with varying air quality conditions. They found that short-term sick leave was 35% lower in offices ventilated by an outdoor air supply rate of 24 l/s compared to buildings with rates of 12 l/s. This staggering statistic may support Dowds “$50 billion a year” in losses claim and suggests that companies should have been investing much more significantly in air quality technology long before the pandemic. Employees not being able to work due to sickness is a huge drain on companies but workplace air quality is not just about reducing sickness either. Air Quality Better air quality also improves the overall health, wellness, and comfort of employees, thereby increasing their ability to concentrate and making them more productive. Several studies have found that high levels of carbon dioxide (CO2), or low levels of oxygen, in offices make us drowsy, affecting our concentration and decision-making abilities. Traditional building regulations have brought about well-insulated office spaces, reducing temperature fluctuations but also reducing the fresh air circulation. Typical outdoor CO2 concentrations hover around 380 parts per million (ppm), while within offices CO2 concentrations were found to be as high as several thousand ppm. All organizations desire greater employee productivity and, therefore, all companies should seek better air quality. Cost-Effective All companies also want to reduce their costs, and while capital investments in better HVAC systems can be expensive, the operational cost reductions from smarter HVAC usually pay off in the long run. Combined with sensors and analytics, HVAC systems can better understand and react to the actual use of spaces in buildings to find new efficiencies, namely by not heating, cooling, and ventilating unused areas of the building. A layer of artificial intelligence applied to HVAC control can go further by using prediction and advanced analytics to find even greater efficiencies as well as better integrating with other systems to meet overall building objectives. AI Commercial Building Report “The quality of the air as a determinant of occupant health, wellbeing and satisfaction is steadily gaining greater recognition. Several of the more sophisticated offerings in this domain tie into building management and HVAC systems together, and are using AI to balance air quality, energy efficiency, and comfort priorities and determine optimal control systems,” explains the recent AI in commercial buildings report. COVID-19 has forced companies to invest in technology that can improve air quality “Others integrate with predictive analytics solutions, providing improved insight into systems maintenance requirements. A number of the solutions also use occupancy data to help drive optimized ventilation and airflow conditions depending on current levels of occupation in a building.” COVID-19 The COVID-19 pandemic has forced companies to invest in technology that can improve air quality in their workplaces, through regulation and public pressure to better protect employees. However, once the smoke clears on this global crisis, office buildings around the world will find their workers are more resilient to many kinds of sickness, reducing absenteeism, and more productive when they are at work, due to the cognitive benefits of cleaner air. Many of the smart technologies required to improve air quality will also drive cost reductions and open the door to other smart systems such as occupancy and space analytics. While challenging almost every business in the world, the COVID-19 pandemic can also breathe new life into the smart workplace.
Sustainability and environmental impact are core issues of the HVAC market in 2020 or any year. During the last year, HVACinformed.com has addressed multiple facets of sustainability in some of our most popular articles. This retrospective will highlight some of the sustainability articles published during 2020 at HVACInformed.com. An HVACInformed.com Expert Panel Roundtable commented on various aspects of sustainability, including the responsibility of HVAC manufacturers to develop more sustainable, energy-efficient products that can reduce a building’s reliance on fossil fuels. Energy consumption pattern Honeywell has launched a platform that incorporates newer technology. Combining self-learning algorithms with building automation, Honeywell Forge Energy Optimization is a cloud-based system that analyzes a building’s energy consumption pattern and adjusts its settings. Heat networks, or district heating, are becoming an ever-greater part of the industry’s involvement Pete Mills of Bosch Commercial & Industrial outlines how cities are using ‘heat networks’ to achieve carbon emission targets in the United Kingdom. Heat networks, or district heating, are becoming an ever-greater part of the industry’s involvement in larger-scale schemes. The ability to help the decarbonization of heat both now and in the future has made them an attractive solution to the new-build sector, as well as those undergoing deep renovation works. Centralized heat generator Generally, heat networks are defined as a system of supply pipes with a centralized heat generator (Energy Center) that serves multiple domestic or non-domestic dwellings. These are usually in different buildings, but sometimes within a single large building like an apartment block or a university campus. Some U.S. cities are taking the lead to make building performance standards mandatory, thus providing additional incentive for customers to invest in new, more efficient and climate-friendly HVAC technologies. New York City has deployed its Carbon Mobilization Act, which will cut six million tons of CO2 annually by 2020. Washington D.C. adopted the first Building Energy Performance Standard, which will reduce energy use in buildings by more than 20%, thereby lowering carbon dioxide emissions by a million tons annually. Improving environmental performance Newer buildings tend to be designed to be ‘green’, but what about older existing buildings, which still represent the largest share of environmental impact? There is more work to be done in the retrofit sector; and improving environmental performance of older buildings often involves ‘deep retrofits’ that are costly and impact multiple factors inside a building. In the COVID-19 era, there is also growing concern about needs such as circulating outside air, increasing humidity, and improving filtration systems even as older buildings seek to become greener. The consistent theme is a need to work toward better-designed, more energy efficient and healthier buildings The consistent theme is a need to work toward better-designed, more energy efficient and healthier buildings. The California Air Resources Board (CARB) is moving forward with rulemaking that sets limits and deadlines to decrease the use of refrigerants with global warming potential (GWP) in the commercial refrigeration market and in the residential and commercial stationary air conditioning equipment markets. Air conditioning systems California regulations are widely expected to influence the direction of other states seeking to regulate GWP of refrigerants. The addition of biodiesel lowers the carbon content (and thus the environmental impact) of heating oil. The U.S. Environmental Protection Agency says biodiesel reduces greenhouse gas emissions, including nitrogen oxide. The process of making biodiesel from renewable and organic sources also boosts the environmental profile. The Wyss Institute at Harvard University has developed an evaporative cooling system that uses a specially coated ceramic to cool air without adding humidity. Researchers say the approach can yield more affordable and environmentally friendly air conditioning systems for the future.
Honeywell has announced expanding its holistic Healthy Buildings Air Quality offering to help improve and measure commercial building indoor air quality (IAQ) with the introduction of Honeywell Electronic Air Cleaners (EACs) with UV Systems and a new line of indoor air quality (IAQ) sensors. Honeywell Electronic Air Cleaners Honeywell EACs with UV help remove impurities from the air as well as provide filtration and disinfection, without significantly impeding air flow. The new IAQ sensors include Honeywell's Particulate Matter Sensor PM 2.5, Total Volatile Organic Compound (TVOC) Sensor and All-in-One IAQ Sensor. Air quality is essential to a healthy building. It can impact occupant health and productivity, energy efficiency and real estate value. The quality of air is affected by the presence of pollutants in the indoor environment that may cause harm. Facilitating cleaner and safer buildings Building owners are looking for ways to create safer, cleaner air to instill occupant confidence" When IAQ is poor, occupants can experience a drop in productivity as well as adverse health effects such as asthma and bronchitis. The concentration of some pollutants can be two to five times higher indoors than typical outdoor concentrations. "More people are paying attention to air quality and the importance of creating healthier environments in the spaces we use for work, school, entertainment and travel," said Manish Sharma, Vice President and Chief Technology Officer, Honeywell Building Technologies, adding "Building owners are looking for ways to create safer, cleaner air to instill occupant confidence as well as attract future commercial tenants." Sensing technology aids in enhancing IAQ Manish added "We're talking to hundreds of customers who are navigating these concerns right now and working with them to update their building systems to better protect occupants. It doesn't always have to be a complicated process of ripping out old equipment and starting from scratch. It can be a straight-forward HVAC upgrade with modifications that address specific concerns and minimize potential side effects.” He further stated, “Sensing technology is an important tool to identify opportunities for adjustments, only when you can measure particles can you properly control them. Adding a system like Honeywell's can improve a building's air quality by filtering particulates and reducing contaminants." Boosting indoor air flow and quality Honeywell EACs use an electric charge to help remove solid and liquid impurities from the air without impeding air flow. The UV System emits ultraviolet light to damage the DNA structure of certain microbes at the cellular level and inactivate various viral, bacterial and fungal organisms – thus providing filtration and disinfection in one system. Ideal for retrofits, property upgrades and new construction alike, Honeywell EACs with UV Systems can be installed inside a commercial HVAC system, without the need to remove old equipment and install a new system entirely. Honeywell EACs can help save energy, while providing a better heat exchange and can pay for itself with the savings. Enhancing IAQ without changing HVAC infrastructure Honeywell IAQ sensors help owners better determine a building's environmental state and air quality status The new Honeywell IAQ sensors help building owners better determine a building's environmental state and air quality status and allow them to take corrective actions through the building management system (BMS) without a need to rip and replace existing sensors. It is possible to add new sensors to existing temperature, humidity and CO2 sensors currently in place within the building or deploy new All-in-one IAQ sensors to cover multiple sensing requirements in one device. Healthy Buildings solutions Honeywell EACs with UV Systems and new IAQ sensors are the latest in a suite of offerings from the company that focus on creating healthier buildings. Honeywell recently announced upgrades to the Pro-Watch and MAXPRO Network Video Recorders and Video Management Systems solutions, which use analytics and artificial intelligence to identify if building occupants are complying with guidelines around social distancing and wearing masks. Honeywell's Healthy Buildings solution help building owners improve the health of their building environments, operate more cleanly and safely, comply with social distancing policies, and help reassure occupants that it is safe to return to the workplace. These Honeywell solutions are part of a comprehensive effort among Honeywell's businesses to come together to quickly develop solutions that are helping important sectors of the global economy recover.
