To conduct virtual simulation control of near zero energy consumption building heating system

monitor and optimize the operation mode of heating system. 169 days heating period of 3 rooms data parameters was collected

set the target value according to the temperature of 23 ℃

and the relative humidity of 60% as the standard

conducts theoretical statistics and data analysis. The results shows that room heating period conversion cost of virtual simulation control system is（15.1 ±1.28） yuan / m~2

about 44% lower than that of central heating; about 9.8% lower than that of existing multi-energy complementary system

and the heating cost of buil

ding was further reduced. Indoor temperature and humidity fluctuate slightly

and PM

mass concentration and φ（CO

） are closer to the material content in the air. The energy saving effect of virtual simulation system is more obvious in near-zero energy consumption building is more obvious

which provides a reference scheme for reducing building energy consumption

realizing controllable heating system and quantitative energy consumption analysis.
