The Centers for Disease Control and Prevention (CDC) has published guidance for businesses seeking to return to work during the coronavirus pandemic. Guidelines include instructions for businesses to ‘improve central air filtration to MERV-13 or the highest [standard] compatible with the filter rack, and to seal edges of the filter to limit bypass.’ MERV stands for Minimum Efficiency Reporting Value. A MERV-13 rating means a filter is able to catch 90% of particles in the 3-10 micro...

HVAC systems should operate to ensure the comfort of individuals, not based on the temperature in a room. That’s the thinking behind a system devised by researchers that uses thermal cameras to measure the temperatures of faces in a room and adjusts operation of the HVAC system accordingly. Among other things, the scheme shifts the focus away from facilities and toward occupants, who reflect a truer measure of system effectiveness. Researchers at the University of Michigan have developed...
