The Energy Impacts of COVID-19 HVAC Mitigation Strategies

What is the energy impact of major HVAC system operation guidance to reduce transmission of COVID-19 inside buildings across the U.S. commercial building stock? Speakers discussed the energy implications of (1) 100% outdoor air ventilation rates, (2) installing MERV-13 filters or better, (3) disabling demand control ventilation, and (4) HVAC flushing mode operation. Analysis of these measures using ComStock providedĀ a national view of the energy implications for various commercial building types in all U.S. climate zones.
