Comparative analysis of indoor air quality in offices with different ventilation mechanisms and simulation of ventilation process utilizing system dynamics tool.

ABSTRACT: Keeping COVID-19 pandemic in perspective, good indoor air quality (IAQ) and adequate ventilation are imperative to minimize risk of virus spread, besides other poor IAQ related risks. Thus, present study is focused on evaluation and comparison of ventilation rates (VRs) in office buildings with different ventilation mechanisms. Two-season (summer and winter) data of indoor CO₂ was collected, and VRs were calculated adopting three methods i.e., transient mass balance, steady-state and decay method, and were then input in system dynamics-based (SD) model for finding best method for the calculation of VRs. In the last part, simulations were used to calculate the optimum VRs to keep indoor CO₂ levels below recommended limits. Results showed statistical difference (p < 0.0
