This study evaluates the capacity of night purging in office buildings to reduce the cooling load. RTS-SAREK is used to estimate the performance of night purging on the steady state. To overcome steady state RTS program limitations, we added unsteady heat transfer equations. When the ACH (Air Change per Hour) increases, the wall temperature decreases in both the steady and unsteady states. The unsteady heat transfer rate is different from the steady transfer rate, which validates the unsteady calculation. When ACH is low, the heat transfer rate increases continuously with time. When ACH becomes higher, the heat transfer rate increases and decreases with time. When ACH is quite high, there exists a large difference in the heat transfer rate between the steady and unsteady calculations, which emphasizes the importance of the unsteady calculation.

This paper introduces the RTS method developed by the ASHRAE. In addition, a load calculation program was developed based on the RTS method and then the calculation logic and procedure are explained in detail. The developed program was designed to allow easy and precise predictions of the building load.

Lots of programs and methods for calculating the maximum and dynamic thermal load of building have been developed and used practically. In this paper we calculated heat load in RTS method and compared them with result using TRNSYS in the same test space.
