夏热冬冷地区公共建筑热工性能评估方法的讨论

Discussion of evaluation method of thermal performance of public buildings in hot summer and cold winter zone

针对《公共建筑节能设计标准》中热工性能评估的个别条款在夏热冬冷地区执行时的疑问,进行了探讨。标准未限定围护结构热工性能强制指标的适用范围,笔者认为不应包括非供暖空调建筑和建筑中的非供暖空调区域;标准规定权衡判断以全年供暖空调能耗为依据,笔者建议供暖空调的设计负荷或全年的累计负荷也可作为权衡判断依据,以简化权衡判断的计算过程。

Discusses some doubts raised in implementing the Design standard for energy efficiency of public buildings as be applied in hot summer and cold winter zone. Application scope of mandatory indexes about thermal performance of building envelopes in the standard is not be limited to heated and air conditioned building and heated and air conditioned area in a building. Trade off option is complex when annual heating and air conditioning energy consumption is the index. Proposes design load or annual accumulated load in place of annual energy consumption to simplify the trade off.
