COVID has us all wondering what’s in the air we’re breathing and recognizing that what we breathe matters. Now more than ever, with our clients mostly indoors, they depend on us to come to the table with the knowledge and expertise to explain IAQ  risks and make design decisions skillfully. This seminar will provide two key perspectives. First, a clear overview of the design principles for healthy indoor air and how to manage exposure risk to various indoor pollutants, including particles, chemicals, and microbes. Second, we will share the results of a quantitative model of transmission risk (Wells-Riley) for COVID and offer actionable insight into the relative impact of various actions that occur as part of a layered risk reduction strategy. 

Vaccines may be the light at the end of the tunnel, but we still need to be on our game. 

Let’s start the year smart and end the pandemic healthy!
