Maintaining IAQ and HVAC During Building Closures

Shelter-in-place orders in states across the country have caused many businesses to cease operations. Until the COVID-19 pandemic is brought under control many facilities will remain empty. While we provide Coronavirus solutions like verification and clearance testing, as well as disinfection services, underlying IAQ and HVAC conditions drastically affect viral spread and return occupancy.  Plus, facilities managers know, an empty building is not a worry-free building. Security and maintenance issues must get addressed. The silver lining in this is that a building shutdown, however temporary, is a good time to perform preventive maintenance and keep indoor air quality at proper levels. Maintaining IAQ and HVAC during building closures is critical to reopening the building for occupancy. Maintenance for HVAC during closures ensures that IAQ issues get resolved and systems get inspected, cleaned, and serviced. The benefits are a safer work environment for occupants when operations resume and a better return on investment on systems equipment and building materials. Opportunity for Preventive Maintenance Preventive maintenance is a plan to prevent problems from occurring. Potential issues could include predictable ...

How HVAC Affects Viruses

With the current COVID-19 Pandemic it more important than ever to understand how HVAC affects viruses and other indoor environmental issues. Indoor air quality is something that many building occupants don’t give much thought to until it impacts their comfort, but IAQ is a critical part of building engineering and maintenance. A building that is not heated or cooled properly or has humidity levels that are not maintained makes it harder for employees to work effectively. Poor IAQ can also affect the health of workers. A well-designed HVAC system that is serviced and maintained with controlled humidity levels limits mold, dust mites, and bacteria throughout the building. More importantly, it limits the spread of viruses. Maintaining Relative Humidity Maintaining relative humidity is an important part of controlling the amount of particulate matter that circulates throughout buildings. Relative humidity (RH) is expressed as a percentage representing the amount of moisture in the air compared to the maximum amount that could be present at a given temperature. Warm air holds more humidity than cold. The EPA recommends a relative ...

Understanding Disinfectants for Emerging Pathogens

Government agencies, medical facilities, educational institutions and other private sector companies, both large and small, are dealing with the effects of the coronavirus pandemic.  Education on how to prevent the spread of viruses in their buildings by understanding disinfectants for emerging pathogens (DEP) is vitally important. As cases spike and mortality rate rises in the U.S., there is encouraging news. The Environmental Protection Agency has released a list of registered disinfectants for use against emerging pathogens that show similar or efficacy higher than needed to eradicate SARS-CoV-2, the virus that causes COVID-19. EPA-Registered Disinfectants The EPA has released a list of disinfectants made by companies that received pre-approval through the agency’s Emerging Viral Pathogen program. The EPA’s guidance for this voluntary program was finalized in 2016. In January of this year, it was triggered in response to the spread of SARS-CoV-2. The program requires manufacturers to submit data to the EPA proving their product’s effectiveness in killing viruses. Once an outbreak occurs, these manufacturers can let the public know about their product’s effectiveness as a disinfectant. The ...

How Poor IAQ Affects Schools

The COVID-19 Pandemic is now inescapable. SO, How IAQ affects schools has never been more important to understand. With in person classroom education in the United States completely shut down, a shift to online learning is underway. Teachers and admin staff are all working from home. However, facility managers, engineers and custodians mostly are all still working to maintain their buildings. Indoor air and environmental quality have been thrust to the forefront of operations. Poor IAQ affects schools on a daily basis, as this article outlines, but those underlying conditions also contribute to a virus’s viability to thrive in the built environment. This is something to keep in mind in conjunction with the points made below.  If fact, with education facilities being closed there has never been a better time to address many of these conditions. We know that poor air quality impacts the health of office workers, but we don’t often think about how it impacts schools. The same loss of productivity, low morale, and absenteeism also occurs in classrooms. The presence of allergens, VOCs, mold, ...
