- Abstract:
- In order to benchmark the energy efficiency standards for residential buildings in China, the Hong Kong building environment assessment method(HK-BEAM)is chosen as the compliance criteria for assessment.The annual energy consumption and the overall thermal transfer value(OTTV)of a baseline residential building prescribed in the Chinese codes and the HK-BEAM are evaluated and compared by the energy budget approach.The results show that in the Chinese codes, the OTTV of the residential building is lower, but the annual energy consumption and the cooling load are higher than those in the HK-BEAM.The annual energy use difference amounts to 13.4%.All the compliance criteria except the ventilation rate and the equipment power in the Chinese codes are set higher than those in the HK-BEAM.However, the compliance criteria of the ventilation rate and the equipment power, especially the ventilation rate, result in much energy consumption, which ultimately induces a high energy budget for residential buildings.
- 为了校验中国的节能标准, 采用能耗预算法, 对中国标准和HK-BEAM中基准建筑的年能耗及建筑总传热数值进行了计算和比较.结果表明, 与HK-BEAM相比, 中国标准中基准建筑的总传热数值偏低, 年能耗和冷负荷偏高, 两标准中的基准建筑年能耗相差13.4%.中国标准中除了通风率和设备功率外, 其他节能标准项都比HK-BEAM标准设定得高.然而, 由于通风率和设备功率2项节能标准(尤其是通风率)会导致建筑耗能较多, 因此中国基准住宅建筑的年能耗预算偏高.
