Distributed sensing for indoor environments: comparing measured and simulated indoor airflow data for complex commercial building interiors

Improved monitoring towards understanding of indoor environmental quality (IEQ) and occupant exposures has become critical for commercial buildings, and a principal public health concern during the current pandemic. Here, we tested IEQ patterns within an industrial factory converted to hybrid spaces for offices, labs, and light manufacturing, serviced by a combination of HVAC, radiant slab, and high-volume, low speed (HVLS) fans. Multi-factor sensors measuring air speed alongside temperature, humidity, and carbon dioxide (CO2) were run in parallel with a computational fluid dynamics (CFD) model, examining multiple boundary conditions to investigate opportunities for HVLS fans to improve workplace safety and well-being.
