Reducing Your HVAC Carbon Footprint: How The Sector Can Become More Sustainable In The Journey To Net Zero
Reducing Your HVAC Carbon Footprint: How The Sector Can Become More Sustainable In The Journey To Net Zero

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.

2021 Technology Trends In The HVAC Industry
2021 Technology Trends In The HVAC Industry

As we look back at 2020, we are all reflecting on the year that was, and what we have learned from it. In the HVAC space, the year provided us with opportunities for growth and change, as we adjusted to our “new normal.” Here’s a look at some of the HVAC trends we see happening now taking hold as we head into 2021. Advancements and applications in indoor air quality - especially in HVAC space (SF / MF / CRE) 2020 was filled with starts and stops with regards to innovation. Covid-19 halted work in some facilities altogether earlier in the year. The pandemic has brought with it a re-energized interest in the air quality around us, especially in the public sector. There has been a newfound imperative in creating indoor air quality solutions that ensure that air is circulated, sanitized and purified to reduce the likelihood of the spread of sickness. This is a massive issue and 2021 will see growing efforts in these areas and the increased introduction of systems that will purify air quality. HVAC building systems Continued push toward energy efficiency (mainly SF but also CRE) Energy efficiency will be an ongoing issue into the foreseeable future. Once we have looked back at 2020’s carbon emission reductions (because fewer people were flying and driving) there will be no turning back. The same can be said for HVAC. Increased efficiency will continue to be an ongoing pursuit in 2021 and beyond. On average, HVAC appliances consume 48% of a household’s total energy usage. The latest generation of smart thermostats that use the newer 410A refrigerant have brought about reduced energy consumption by up to 35% optimizing how HVAC building systems are operated (reducing the possibility of leaving the AC on too long, and when it’s not necessary to use). convenience and energy savings Increase in supply chain management / platform services HVAC services such as those that collect and manage data including HVAC unit age, efficiency and condition at the property and portfolio level will continue to see increased adoption. These convenience and energy savings they provide is being seen in the multi-family and commercial space, especially with some building owners having been grounded by the pandemic in 2020. New construction had a role in expanding interest in HVAC asset tagging and helping it gain traction in the industry The data gathered by these services can be used in the future to predict HVAC system failures with significant accuracy before they happen. The convenience and potential cost savings acquired by implementing these services will continue to push their popularity into 2021. Additionally, it is interesting to note that new construction in 2020 had a role in expanding interest in HVAC asset tagging and helping it gain traction in the industry. Cataloguing HVAC assets ensures the follow up and guarantees that warranty registration holds and can help track future maintenance during a hold. At the time of sale, the current owner can present true data of the maintenance of these systems, which can increase the current value of the property and can also be used as a tool in negotiation. performing regular maintenance Remote monitoring can be the end to end solution that completes the action behind the alert (CRE mainly) Remote monitoring will continue to see adoption in 2021. Service providers will continue to rely less and less on clients identifying and reporting a problem a heating/cooling issue. The complaint from the tenant may come in some hours after the problem actually starts, and then by the time they get a service request completed, several hours more. And by the time the contractor is on the scene, it is likely more time has elapsed. Remote monitoring also results in regular maintenance, extending the lifetime of a HVAC system. By proactively performing regular maintenance, the overall costs of maintaining a system can be reduced by 40 percent, in addition to ensuring that units are always using the least amount of energy necessary. seamless customer experience Consolidation of HVAC services and equipment - the way people buy - turnkey integrated services One stop shopping for HVAC services and equipment gained popularity in 2020 One stop shopping for HVAC services and equipment gained popularity in 2020 and we will continue to see increased traction in 2021. There are many reasons why developers what to buy equipment directly from the manufacturer, such as convenience, working with a supplier because of its reputation, cost and guarantees on product and services. As more developers buy equipment directly, these manufacturers are responding by helping out with mechanical drawings. This process cuts down the supply chain, allows certainty that correct equipment is quoted, and saves money. The HVAC industry is also turning the corner in becoming more proactive in remediating failing assets and contractors are redoubling their efforts to provide a seamless customer experience increasing customer satisfaction for multi-family communities as well as other means of optimization of services that positively impact tenants, helping increase retention. HVAC providers that can manage the entire process from installation, to job request to invoicing, even reporting and tracking for each job, will be increasingly in demand in 2021.

Inverter Maintenance For Aircon Engineers
Inverter Maintenance For Aircon Engineers

Inverter driven air conditioning is more energy efficient, cheaper to operate and more profitable to install than its non-inverter driven equivalent. Here Neil Ballinger, head of EMEA at automation parts supplier EU Automation, explains how HVAC engineers can maintain the inverters in their customer’s aircon units. Do you remember cross country at school? It was exhausting; miles of seemingly pointless jogging and sprinting and, if the teacher was not looking, walking. If you were unlucky enough to be born before modern safeguarding measures were introduced, it probably also meant getting lost in the nearest woods.Why isn’t every installation an inverter driven unit, instead of the traditional single stage or dual stage models? My PE teacher, who seemed particularly vicious at the time, but in retrospect just knew about sports science than most, used to make us do something called fartlek as well. This meant long distance runs, incorporating elements of speed training by mixing up sprints with jogs and walks. The worst bit was starting to run again after a walk. That is exactly how the motor in your customer’s air conditioner feel if the units you fit are not inverter controlled. The motor has to act just like a runner doing fartlek — it sprints continuously, operating at full speed until the thermostat tells it the room is cool, then it stops. When the room gets warm, it starts again, powers immediately up to full speed and repeats the process indefinitely. Just like a teenage cross-country runner, it is the starting and stopping that is the tough bit. Furthermore, the unit probably doesn’t have to run at full speed to keep the room at the correct temperature, if the motor were inverter controlled it would speed up and slow down as the temperature fluctuates. Why isn’t all aircon inverter driven? We all know that inverter driven aircon is better than its non-inverter driven cousins. It can provide heating as well as cooling and the lifetime cost of use is less for the customer — because their energy bills stay low. The cost of installation is also higher because it is a more complex job, so it works out better for the contractor. It’s a win-win. The research firm Technavio even lists it as one of the key technologies driving growth in the HVAC market in its annual reports every year. So, the only question is, why isn’t every installation an inverter driven unit, instead of the traditional single stage or dual stage models?When contractors contact EU Automation to buy automation parts, for the units they maintain, they have given us another reason: maintenance Cost is a factor, but when contractors contact EU Automation to buy replacement motors and inverters, and other automation parts, for the units they maintain, they have given us another reason: maintenance. As HVAC engineers, we are not necessarily specialists in power electronics, and this makes inverter maintenance daunting. Microcontrollers and IGBTs (Insulated Gate Bipolar Transistors) are not beyond us by any means, but they can be intimidating. Personally, I would back an electrical or heating engineer over an electronics specialist in a problem-solving contest all day long; but that doesn’t solve the problem at hand. Furthermore, while we are experts in air conditioning brands, and know our Daikins and Grees from our Mitsubishis and Fujitsus, we don’t necessarily have contacts at the inverter manufacturers. Amtech, Danfoss, Vacon and Yaskawa are all names we know, but the local dealer for any of them is probably not in your phone book. This is especially true if the unit you need is from a first-generation inverter driven aircon unit and well over a decade old. While we are experts in air conditioning brands, and know our Daikins and Grees from our Mitsubishis and Fujitsus, we don’t necessarily have contacts at the inverter manufacturers Maintenance techniques While inverter maintenance can be daunting, it isn’t difficult. The tools you will need most often are nothing more than a rag and a spanner, while the more esoteric kit is stuff you probably carry anyway, a laptop, vacuum and a Fluke meter. Before you start, remember that while we tend to refer to an inverter as an inverter, the manufacturers themselves, and many of the sources of information online, often refer to them as VSDs (Variable Speed Drives), VFDs (Variable Frequency Drives) or just plain old drives. As a result, when you are searching online for a video to explain something, it’s worth using all three of those terms, alongside the inverter manufacturer’s name and the problem to make sure you get the right result.While inverter maintenance can be daunting, it isn’t difficult When you do move on to maintenance, step one is simple; make sure that the unit is free of dust. This is as easy as vacuuming the heatsink with an ESD (Electrostatic Discharge) vacuum cleaner when you perform routine maintenance or investigate a problem. While you are checking for build up of dust and daily grime, check the filters. They will probably have to be replaced during annual maintenance, but high use might mean they need to be replaced more often. The control panel itself should be well ventilated and free of dust as well, if it isn’t it can overheat, which is the number one cause of inverter damage and the most common reason contractors contact us for replacement units. Before you put your vacuum and duster away, you should make sure that the inverter unit’s location is clean and as sheltered from the elements as possible. Because it’s normally situated on a roof, it’s not going to be perfect, but the units are designed to take a limited battering. That doesn’t mean it’s okay for them to be covered in leaves, surrounded by rubbish or immediately beneath the guttering outlet though! Before you put your vacuum and duster away, you should make sure that the inverter unit’s location is clean and as sheltered from the elements as possible Get out the spanner Once you’ve finished these steps, you are done with dusting for now, it’s time to get out your screwdriver and your spanner. Step one is to make sure the fans on the inverter are operating normally, without noise and with nothing blocking their rotation. The fan keeps the internal components running effectively, just as it does on PC, and if its function is impaired the capacitors will overheat and the inverter will fail.When you install or maintain an inverter on an air conditioning system, it is a sensible precaution to back up the drive parameters to your laptop The next job is to grab your spanner and make sure the power terminals are on tight. Loose connections cause arcing, overheating and even melting of components and are easily checked during any kind of maintenance and repair. While we are still in the realms of the work your apprentice can do with their eyes closed, you should also make sure that the inverter’s removable LCD control pad is stored sensibly and not continually attached to the drive. If it remains attached, there is a chance the display will stay on permanently, which means that when you need it to diagnose a problem, it will probably already be burnt out. Break out the laptop When you install or maintain an inverter on an air conditioning system, it is a sensible precaution to back up the drive parameters to your laptop. It takes minutes and is normally done by using the removable LCD control. In fact, it’s often as simple as selecting ‘PARs’ and then ‘BACKUP’ from the menu. If you struggle, there are lots of videos on YouTube, like this one, which explain the process for each drive. As a result, if the inverter ever does need replacing, you can whip out your backed up parameters and order a new or refurbished one easily, before reloading the parameters to the replacement and getting up and running in no time. Your customers will think you are a power electronics genius, as well as a HVAC expert, and they will be loyal for life; especially of you save them on a hot day! If you follow these simple measures, you will find that the inverters in your customer’s air conditioning units last much longer and no motors will have to run the equivalent of a cross country, thanks to a lack of inverter control.

Aircuity Shares An Insight On Beyond COVID-19 To The Vast Benefits Of Cleaner Workplace Air
Aircuity Shares An Insight On Beyond COVID-19 To The Vast Benefits Of Cleaner Workplace Air

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.

2020 Rewind: Highlighting Sustainability In The Age Of Climate Change
2020 Rewind: Highlighting Sustainability In The Age Of Climate Change

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 Unveils Honeywell Electronic Air Cleaners With UV Systems And New Line Of IAQ Sensors
Honeywell Unveils Honeywell Electronic Air Cleaners With UV Systems And New Line Of IAQ Sensors

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.
