Research on Performance-Based Design of Residential Energy Saving Based on Solar Energy Utilization

以提高居住建筑辐射热利用效果与质量为目标导向,应用正交试验和敏感性分析,在DesignBuilder软件模型上,采用“性能反馈循环”的技术工作思路,细化分析、比较建筑师可控的平面布局、立面窗墙比、围护结构等设计要素中的能耗敏感因子。在太阳辐射资源富集条件下,探索了便于建筑师操作的住宅节能性能化设计方法,将建筑节能的技术过程转换为具体的设计方法,建立了能耗模拟计算与方案设计推敲间的互馈关系。研究表明,在太阳能富集地区,合理的能耗敏感因子搭配可实现住宅能耗降低30%以上,具有良好的节能潜力。

Aiming at improving the utilization effect and quality of radiant heat in residential buildings,this paper applying orthogonal experiment and sensitivity analysis,,and adopts the technical working idea of“performance feedback cycle”was adopted in the Designbuilder software model to refine and compare the energy consumption sensitive factors in design elements controllable by architects such as plane layout,facade window wall ratio and enclosure structure controlled by architects.Under the condition of abundant solar radiation resources,the performance-based design method of residential energy conservation convenient for architects was explored.the technical process of building energy conservation was transformed into a specific design method,and the mutual feed relationship between energy consumption simulation calculation and scheme design was established.The research showed that in solar energy rich areas,a reasonable combination of energy consumption sensitive factors could reduce residential energy consumption by more than 30%,which had good energy-saving potential.
