Abstract At present, many office buildings in Xinjiang generally use continuous movement of heating and cooling systems, heating and cooling excessively caused the energy waste, the use of intelligent control equipment system can effectively save energy. This paper uses the parametric performance simulation toolset (Ladybug tools) to model the energy consumption of office buildings in four typical climatic regions in Xinjiang. It simulates two methods of intelligent control (ICS) and continuous operation (COS) in different window-to-wall ratio (WWR) the influence of heating and cooling energy consumption load. Considering the additional equipment energy consumption ( ΔE ) of ICS, the control energy saving rate (ƞ) is compared ICS with COS. The results show that in different climate zones and with different WWR, ICS is more energy-efficient at the heating and cooling methods than COS. Moreover, in different climate conditions, office buildings with different WWR have different energy-saving rates. The change of the WWR has a small effect on the η value in the Severe Cold Zone C, and the η value in the Cold Zone A region decreases with the WWR becomes larger. This study further proves that the contribution of intelligently controlled heating and air-conditioning systems of building energy conservation and provides a favourable basis for refined energy development.
