The past 12 months have been a challenge for businesses and that’s putting it mildly. Facilities directors prepare for many contingencies in a given year, but a global pandemic was not high on the list. Indoor air quality and the safety of building occupants are always a priority, however. That said, as we pass the historic milestone of the COVID-19 shutdown, it’s a good time to look back and ask, is your COVID HVAC strategy keeping up?
What We’ve Learned About SARS-CoV-2
The science has only become clearer over the past year: the SARS-CoV-2, or coronavirus, is transmitted, at least in part, through aerosol transmission. The virus attaches to the tiny droplets of water expelled by coughing and sneezing. These droplets then remain in the air for hours at a time. Some land on hard surfaces where they transfer by touch.
To combat the spread of the coronavirus, building managers put social distancing and handwashing guidelines into effect. A change to building traffic patterns and increased disinfecting also began. The addition of air purifiers in nursing homes, gyms, spas, retail shops, and the classrooms of schools and universities also increased. All of these things are just a part of building COVID strategies.
In addition, ASHRAE’s Epidemic Task Force (ETF) updated their recommendations on reducing airborne infections. As far as HVAC system operation, ASHRAE recommends maintaining temperature and humidity design set points. As well, buildings must provide a clean air supply to match occupancy, flush spaces between periods of occupancy, and limit the re-entry of contaminated air. These updated recommendations should inform the COVID HVAC strategy of businesses. However, one thing that has remained consistent is the emphasis on increasing ventilation. In other words, a greater amount of outside air brought into the indoor environment lowers the number of contaminants in the air. There are some simple methods and systems building managers can employ to maintain proper ventilation and keep their COVID-19 HVAC strategy on track.
3 Ways to Keep Your COVID-19 HVAC Strategy on Track
First, using a combination of methods and programs, Pure Air Control Services helps building managers meet their IAQ goals. Second, these methods assist building managers with their COVID-19 HVAC strategy while meeting any codes and standards that may apply. Finally, they also have cost-saving benefits by keeping energy costs low.
1. HVAC Hygiene Assessment
Our HVAC Hygiene Assessment helps facilities directors understand the impact of their HVAC system on IAQ. The assessment includes a visual inspection of the air handling unit, evaporator coils, drain pan, blower, and ductwork. Our EDLab tests collected samples for the presence of bacteria, viruses, fungi, and other pathogens. Once completed, a detailed report helps building managers adjust the COVID HVAC strategy.
2. PURE-Steam AHU Disinfection & Cleaning
Another important part of a COVID-19 HVAC strategy is PURE-Steam HVAC coil cleaning. This method uses high-temperature steam to clean and restore the air handling unit to near factory specification. The process removes viruses, bacteria, mold, and allergens by pushing them through the evaporator coil. Plus, the PURE-Steam method helps keep the HVAC system in top running condition so it improves indoor air quality. This steam cleaning program is certified by the Green Clean Institute so you can trust that it is energy efficient.
3. Environmentally Engineered PURE-Duct Cleaning
The PURE-Duct hygiene duct cleaning process gets inside the ductwork using high-pressure air turbulence to dislodge built-up dust and debris. Next, loose particles get collected using an industrial-strength vacuum system with a HEPA filter.
