目前普遍的建筑节能工作过于重视空调能耗,分析空调能耗时又过于重视空调负荷,而分析空调负荷时又过于重视围护结构的优化。从而,照明、设备、被动式策略等其他节能的重要因素往往被忽视。建筑设计的各阶段中,最初的方案阶段是节能潜力较大但却较容易被忽视的阶段。因为在该阶段缺乏建模的输入条件,模拟分析难度相对较大。同时,目前的节能规范局限在围护结构和系统设备的参数限定上,而评价标准局限于“条目罗列式”的评价方法。这些方式提升了可操作性,但很多情况下无法正确地引导节能设计。鉴于以上分析,笔者提出一种新的建筑节能设计方法,该方法着眼于实现最小的建筑整体能量需求,立足在建筑方案设计阶段,开发一个“预测优化”的程序,合理地对建筑方案设计进行模拟辅助设计优化。 The current widespread energy-saving construction work places too much emphasis on energy consumption of air-conditioning, air-conditioning analysis of energy consumption is too much emphasis on air-conditioning load, and analysis of air-conditioning load too much emphasis on the optimization of the envelope structure. Thus, important factors such as lighting, equipment, passive strategies and other energy savings are often overlooked. Of the various phases of architectural design, the initial program phase was a phase that had a large but potentially negligible potential for energy savings. Because of the lack of modeling input conditions at this stage, simulation analysis is relatively difficult. At the same time, the current energy conservation standards are limited to the parameters of the envelope and system equipment, and the evaluation criteria are limited to the evaluation method of “item list”. These ways improve the operability, but in many cases can not guide the energy-saving design correctly. In view of the above analysis, the author proposes a new design method of building energy efficiency, which focuses on the realization of the minimum energy demand for the whole building. Based on the design stage of the building program, the author develops a “forecast optimization” program, Design simulation-aided design optimization.
