Live Session from ASHRAE Virtual Conference

Effects of Building Ventilation on SARS CoV 2 Transmission, a Preliminary Study by Yuguo Li

The once-in-a-century Covid-19 pandemics continues to spread. Implementing an appropriate level of intervention has not been easy, as the relative importance of different transmission routes is unknown. One important question related to HVAC is whether the new coronavirus SARS-CoV-2 can be transmitted by the airborne route.

ASHRAE Journal Podcast
'If you were waiting for the opportune moment, this is it.'
Epidemic Task Force Chair William Bahnfleth, Ph.D., P.E., Presidential/Fellow ASHRAE, and Jason DeGraw, Ph.D., Member ASHRAE, discuss the task force’s guidance, including its Core Recommendations, and how the COVID-19 pandemic could create long-lasting change in the HVAC&R industry.

Air Quality in schools: At the intersection of technology and equity
Anisa Heming and Corey Metzger of the U.S. Green Building Council and ASHRAE discuss a new report on schools’ efforts around the country to protect against COVID-19 by improving indoor air quality. Like so much else about schools, air quality comes down to resources, in this case, for infrastructure and maintenance. Also, there has been no central source of reliable information for district administrators. While COVID-19 has drawn our attention to air circulation and ventilation, there are other reasons to be concerned about air quality. Not only are there other airborne pathogens, but studies show that learning improves with better indoor air quality.

IREM: From the Front Lines
HVAC Operations
Wade Conlan of the ASHRAE Epidemic Task Force discusses best practices around HVAC operations including air filtration, potential supply chain issues and best practices for reopening.
