摘要
建筑节能是绿色建筑的重要组成部分,而建筑能耗模拟是进行建筑节能设计的关键技术手段。建筑能耗模拟技术较为复杂,涉及几何建模、能耗计算模型选择、建筑热工参数设置、建筑运行状态描述、设备系统建模等环节。因此,采用标准化方法进行建筑能耗模拟十分必要,能够确保模拟过程的可靠性和模拟结果的准确性。本文比较了英国、美国、加拿大三国的建筑能耗模拟标准化方法,包括能耗模拟软件、气象文件、几何建模、热工分区、围护结构参数、运行时刻表等缺省值。发现尽管核心内容基本相同,但在很多技术细节的规定上存在差异。进一步利用三国能耗模拟标准化方法对同一栋案例建筑进行了能耗模拟分析,发现能耗强度差异达到12%。
Building energy efficiency is an important part of green building, and building energy simulation is the key technical means for building energy saving design. Building energy simulation technology is quite complex, involving geometric modeling, energy calculation model selection, building thermal parameter settings, operation description, equipment system modeling and other aspects. Therefore, it is necessary to use the standard methodologies to simulate the building energy consumption. This paper compares the building energy simulation methods in the United Kingdom, the United States and Canada, including energy simulation software, weather documents, geometric modeling, thermal partitioning, envelope parameters, and operating schedule. It’s found that although the core content is basically the same, there are many differences between the technical details. Then the energy simulation analysis of the same case building is carried out by using the different standard methodologies on building energy simulation, and the difference between energy consumption is found to be 12%.
