The September 2022 report by R-Zero Systems Inc. addresses the pressing need for enhanced indoor air quality (IAQ) management amid persistent concerns about respiratory viruses post-pandemic and the associated challenges faced by organizations in meeting these new ventilation requirements. It elucidates why most Heating Ventilation Air Conditioning (HVAC) systems were not originally designed to comply with the updated IAQ standards and why existing HVAC upgrades often fall short. Introducing a proven and cost-effective technology known as upper-room ultraviolet germicidal irradiation (UR-UVGI), the report highlights its capability to meet the standards at a fraction of the cost. Notably, several agencies, including the US EPA and ASHRAE, have recommended the adoption of this technology for effective IAQ management.
