夏热冬暖地区ρ值对能效测评结果的影响

Impacts on Building Energy Performance Evaluation for ρ in Hot Summer and Warm Winter Zone

基于PKPM建筑能效测评软件,将夏热冬暖地区某典型的居住建筑作为案例建立能效测评模型,以外围护结构的太阳辐射吸收系数ρ值为影响因素,分析相对节能率η和建筑能效测评星级的影响。计算表明ρ值越高,η值越低,建筑能效测评标识星级越低。

Based on a typical residential building in hot summer and warm winter area zone, the PKPM building energy performance evaluation software was used to establish energy performance evaluation model. The relationship between the peripheral solar radiation absorption coefficient value （p） and the structure of the relative energy saving ratio（q）, the building energy performance certification were analyzed. Calculation results show that the higher the value of p, the lower the value of 7, and the lower the building energy performance certification.
