This five-year project aims to model the transport of harmful biological and chemical compounds in urban environment using different modeling techniques, such as computational fluid dynamics and multizone modeling for indoor airflow, Modelica-based modeling for HVAC system and control. The project is led by Lawrence Berkeley National Laboratory and in collaboration with many federal research laboratories and industry partners. In response to the COVID pandemic, our team has investigated various mitigation strategies, including 1) placement of portable air cleaners in a conference room; 2) HVAC operation strategies for office buildings during COVID and their energy consumptions. 

Comparison of the streamlines

Comparison of the streamlines, colored by the local velocity magnitude, coming from the portable air cleaner (PAC) inlet in (a) the fully occupied (F) and (b) the socially distanced (D) room setups for the PAC setting 1BL. (Castellini et al. 2021)
