This paper describes the simulation results of a fabric heat storage system. The effects of operating method of the air-conditioning unit, internal heat generation and building thermal specification on the fabric heat storage system were examined in order to evaluate the total system performance. From the first stage of simulation study, the outlet air temperature of 12℃ with the combination of cooling storage hours of 5 hours for July and August and 3 hours for June and September was considered as the standard operating condition of the air-conditioning unit. From the simulation results using the standard condition, it was found that the peak cut ratio was 30% and the increased cooling coil load was 10% for the fabric heat storage system compared with the usual air-conditioning system. For the comparison of the effects of three levels of internal heat generation, the increased amounts of the electric consumption were 17%, 10% and 8% for small, middle and large levels respectively, while the reduced amounts of the daytime electric consumption were 37%, 29% and 22% for small, middle and large levels respectively. The building thermal specification and the window area showed only small effects on the system performance.
