Normative Building Energy Models for Buildings with Intermittent Air Conditioning System Operation -Applicability and Accuracy

Guang Yang, ，zhengwei Li, ，yingjun Ruan

Abstract: Intermittent air conditioning (AC) system operation is quite common in developing countries, which is featured by turning on/off air conditioning systems to meet dynamic building loads. Due to the inherent uncertainty and vast variation in intermittent AC operation behavior, it is quite challenging to model the energy performance of buildings with this kind of operation. Normative models have the advantages of simplicity and fastness, and can achieve good accuracy when modeling the energy performance of existing buildings. This paper presents a systematic study to evaluate the applicability of normative methods for buildings with intermittent AC operation. In this study, five government office buildings in Qingdao city with different AC operation behavior were chosen as the testing cases. The results show that multiple operation behavior exists in the investigated buildings, and normative methods are less accurate when predicting the energy performance of buildings with intermittent AC operation.
