Indoor Air Quality Enhancements
Over the past few months the hot topic for the world is the coronavirus and indoor air quality. From this heightened interest, many building owners and property managers have been asking what can be done to improve the air quality in their offices and business environments. To help address this, we are providing this summarized outline.
While there is currently nothing specific being called out as able to prevent the spread of the coronavirus, there are a variety of things that can be done to improve the indoor air quality of any environment. From the recent reiteration of ASHRAE 62.2.2019’s “Position Document on Airborne Infectious Diseases,” we have developed the following summary.
Four Key Ventilation Areas to Enhance Air Quality
# 1 – Dilution of Pollutants through an Increase in Fresh Air
This recommendation speaks to the current “fresh air %” provided to the space from the building’s ventilation equipment, and suggestions of what can be done to increase it for the sake of internal air quality.
# 2 – Decrease of Pollutants through Better Filtration of Recirculated Air
The quality and capability of your HVAC filters is something that can be improved by adopting a more frequent filter change policy and looking into your current filters “MERV” rating for potential improvement.
# 3 – Lessening of Susceptibility through Control of Humidity Range
The quality of air is influenced by the % of relative humidity in the space. The ideal range of humidity for a controlled environment is 30% to 50%. Too dry and mucous membranes in the nose and throat dry out, making us more susceptible to colds and respiratory illness. Too moist of an environment is conducive to mold spores, dust mites, and pollen which also promote respiratory issues, allergies, and asthma.
# 4 – Decrease of Pollutants through Improvement of Air through UV/Ionization
If airborne microbial bacteria, virus, and mold are of major concern, there are several levels of ultraviolet light solutions that can be applied to better the air quality of your ventilation. The levels are:
- “Coil mount UV Lighting” - Evaporator coil and condensate pan irradiation *
- “Duct/Airstream mount UV Lighting” – Air irradiation through UV *
- “Photo Catalytic Oxidation” – Air irradiation through UV & natural chemistry *
- “Bipolar Ionization” – Air purification through distribution of negative Ionized molecules *
* Please note: Each of these recommendations have application pros and cons which need to be considered as you select the best course of action for your needs.
