Abstract: This study compared fixed Cooling Seasonal Performance Factors (CSPF), calculated with a general outdoor temperature distribution, to those calculated considering specific climates and Room Air Conditioners (RAC) usage. The results indicate that tailoring CSPF calculation to such conditions is a key to better communicating RAC efficiencies to stakeholders. Additionally, using Building Performance Simulation was proved as an innovative approach within this scope since it may tailor CSPF calculation to specific hours in which indoor conditions are more likely to demand cooling use. This practice also highlighted equipment-related outcomes that static evaluations could not detect.
