Abstract: Our research evaluated a comprehensive set of key performance indicators (KPIs) for passive or low-energy building technologies (hereinafter, “strategies”) for pre1980 medium office buildings in Phoenix (AZ) and Chicago (IL). The strategies included cool roofs and cool walls to reduce solar heat gain, natural ventilation to remove excessive indoor heat, and ceiling fans to allow the cooling set point to be increased. Using EnergyPlus and Python scripts, we assessed major KPIs for buildings with and without mechanical cooling. The analysis offered how each strategy can save energy in cooled buildings and help occupants of uncooled or inadequately cooled buildings adapt to increasingly frequent extreme heat events.
