气候变化引起了许多研究人员和实践者的关注，他们关注如何应对实现低碳建筑和城市以及未来发展所面临的挑战。然而，很少有研究探讨了正交试验设计（OED）方法的应用，以优化建筑设计的最低碳排放的建筑运营能耗。本文旨在利用OED理论，提出一种以建筑运行能耗碳排放最低为目标的建筑围护结构优化设计方法。首先，根据建筑传热学的基本原理，分析了建筑能耗计算的方法，包括基于稳态传热理论的简化算法和基于非稳态传热理论的动态模拟方法。对建筑能耗影响因素的分类进行了研究和探讨。基于OED的基本概念和原理，以江苏省南通市某公共建筑为例，进行了OED视角下的案例研究。选取了影响建筑运行能耗的6个因素：外墙类型、窗框类型、玻璃类型、屋顶类型、楼板类型和遮阳类型。最后根据全年累计负荷的指标确定最优方案的选择。最后利用天正建筑能耗软件计算了最佳案例的运营能耗。该研究将为建筑围护结构设计提供一种新的优化方法，使建筑运行能耗的碳排放最低。
Climate change has drawn the attention of many researchers and practitioners to focus on the methods to address the challenges in achieving low-carbon buildings and cities and in future developments. Nevertheless, few studies have explored the application of orthogonal experimental design (OED) method to optimize building design for the lowest carbon emissions of building operational energy consumption. This paper aims at developing a new optimization method to building envelope design for the lowest carbon emissions of building operational energy consumption using OED. Firstly, according to the basic principles of the building heat transfer, the method of building’s energy consumption calculation is analyzed, which includes the simplified algorithm based on steady-state heat transfer theory and the dynamic simulation based on the unsteady heat transfer theory. The classification of the building energy consumption influencing factors are then investigated and discussed. Furthermore, based on the basic concept and principle of OED, a case study from the perspective of OED has been conducted, which involves a public building in Nantong, Jiangsu province. Six influence factors of building envelope to building operational energy consumption are selected as follows: exterior wall type, window frame type, glass type, roof type, floor type, and shading type. Selection of optimal case is then determined by the index that is based on the year-round accumulative total load. In the end, Tianzheng Building Energy Consumption Software is used to calculate the optimal case operational energy consumption. The research would provide a new optimization method for building envelope design to the lowest carbon emissions of building operational energy consumption.
