Change Environments Not Behaviors: How Active Air Filtration Can Help the UK Come Out of Lockdown Long-Term

According to the latest statistics, Britain now has the highest daily COVID-19 death rate in the World, following an unfortunate record month of fatalities during January 2021. While UK Government is quick to defend this statistic, the fact remains that our country has been crippled by the SARS-CoV-2 virus, and now, as the population battles through yet another lockdown, it seems that the only 'way out’ is through widespread vaccination. impact of COVID-19 Though imperative, this strategy emphasizes the real challenge that Governments across the globe have faced in trying to control this virus; that reducing the transmission or ‘R rate’ is reliant on the behaviors of people. People who have lived with some form of restrictions for too long, people who are frustrated and tired of the impact COVID-19 has had on their businesses, and people who have simply lost trust in Government U-turns and last-minute decisions. What’s more, despite the best efforts of millions to comply with restrictions, the virus itself is one that is hard to contain, particularly with asymptomatic cases unknowingly passing it to others in key locations like supermarkets or via public transport. Regardless of this challenge, there is a solution that doesn’t rely on changing people’s behaviors, but rather in changing the environment in which people live, work and socialize. That solution is the implementation of Active Air Purification Technology. What Is Active Air Purification Technology? Active air purification technology is effective in every cubic cm of indoor air and surface space simultaneously and continuously Most air purification technologies are passive in that they can only have any effect when the air containing the pollutant comes into close proximity or passes through the unit. Examples of this are filtration, UV-C, and various PCO and ionization technologies. In other words, certain operational conditions must be met in order for them to be effective. Active air purification technology is not limited in this way and is effective in every cubic cm of indoor air and surface space simultaneously and continuously. This means pollutants, like viruses and bacteria, are instantly treated no matter where or when in the indoor space they are emitted or exposed which is significant in the context of COVID transmission. Whether required to mitigate microbials, allergens, or dangerous gases and VOCs, active technology offers a unique solution to destroying microbials instantly, offering a safer, cleaner, and more effective approach to air purification in domestic, commercial, and industrial environments. REME Air Purification Technology REME is an active air purification technology developed and patented 15 years ago by RGF Environmental Group, a COVID critical environmental innovator and manufacturer headquartered in the United States. Using no chemicals or harmful substances, REME comprises a number of known air purification technologies and sciences in one product. Its active capability works by producing and maintaining similar concentrations of hydrogen peroxide molecules as those found in the outdoor air and combines a process of bipolar ionization. When coming into contact with microbials, the naturally occurring ionized molecules break them down, destroy them and then revert them back to harmless water vapor and oxygen. The bipolar ionization effect causes other airborne particulates to agglomerate together causing them to become larger and heavier and drop out of their air or get captured in HVAC filters. RGF’s REME air purification technology produces 1 quadrillion ionized hydrogen peroxide molecules every second, quickly and safely killing any airborne virus or bacteria, including SARS-CoV-2 on a continuous basis. Its effectiveness has been verified by nationally accredited independent labs and testing bodies in the US and by other governments in numerous tests over two decades, with results also confirming a 99%+ inactivation for highly infectious viruses and bacteria, such as H1N1 or ‘Swine Flu’, SARS, Norovirus, MRSA and Bird Flu, just to name a few. Vaccinate Environments And People Air purification technology drives down the R rate for good by effectively vaccinating the air in which the virus circulates In understanding exactly how active air purification technology works and its capability to successfully destroy COVID-19, it’s clear that it presents an opportunity to drive down the R rate for good by effectively vaccinating the air in which the virus circulates. This strategy is already working its way through the United States with leading brands, like restaurant chain TGI Friday, installing active air purification technology across all establishments and has also caught the attention of renowned insurance market, Lloyds of London, which has installed the technology across all UK offices to ensure its 5,000 plus staff members can return safely to work. Improving the environment For nearly 12 months the world has been coping with COVID-19, describing it as an ‘unprecedented period’ where there is no clear end. However, in vaccinating both people and the environment in which it lives, the virus can be controlled once and for all. Ultimately, with a crippled economy, in excess of 100,000 deaths and a generation of children impacted by the closure of schools, now is the time to accelerate response and change the environments in which the virus circulates, not just the people.

Green Buildings Or Healthy Occupants? You Don’t Have To Choose Anymore!

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

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