New Tool for COVID-19 Building Risk Assessment & Reduction Guidance

Is your building’s HVAC system helping or hurting the spread of COVID-19 in your building?

The debate is raging: How much is COVID-19 spread through airborne transmission? While this risk was generally thought to be low, 239 scientists are now convinced that airborne transmission is an important pathway for the spread of the Coronavirus (1), especially in indoor environments. If this is true, your building’s HVAC system plays an important role in either controlling or spreading infectious pathogens throughout your building.

Assessing risk and evaluating measures for mitigating the spread of COVID-19 in buildings is daunting for many building owners. That is because today’s buildings and HVAC systems are technically complex and misguided changes can have unintended consequences to the health and comfort of building occupants, and often result in significantly higher operating costs. The best decisions are informed, rooted in reality, and punctuated with perspective.

To help you get on track with your building, Optimized Systems has developed a risk assessment tool that includes explanations of HVAC-related options for reducing COVID-19 infection risks that you may wish to consider. This tool is available to you free and may be accessed at
