出身背景最近，在能源供应有限的时代，越来越需要更准确地预测我们建筑的能耗。原因是，建筑业主和设计师已经开始评估拥有和运营建筑的生命周期成本以及第一成本，以便在建筑和机械备选方案之间进行有效的比较。建筑的首个成本不再是经济评估的唯一因素。现在，建筑物消耗的未来能源是决定建筑物在初始施工期间进入何种环境控制系统的一个重要决定因素。建筑物未来能源使用的详细分析对设计过程的重要性，与建筑设计师每天使用的任何其他分析工具一样，不仅从经济可行性的角度，而且从可能适用于所有未来建筑物的能源标准的角度来看。 这些考虑因素推动了rel的研究！明确了建筑能耗分析的方法，从而发展了这种天气模拟模型。引文:华盛顿州西雅图ASHRAE学报第82卷第2部分研讨会

Background. Recently, in times of limited energy supplies, there has been a growing need to predict more accurately the energy consumption in our buildings. The reason for this is that building owners and designers have begun to evaluate the life-cycle costs of owning and operating buildings as well as the first costs in order to make valid comparisons between architectural & mechanical alternatives. No longer is the first cost of a building the only factor in an economic evaluation. The future energy that a building consumes is now a streng determinant in deciding what environmental control systems go into the building during its initial construction. A detailed analysis of buildings' future energy uses is becoming as crucial to the design process as any of the other analytical-tools which are in every day use by building designers not only from an economic feasibility viewpoint but also from the viewpoint of energy standards which may be imposed on all future buildings. These considerations are what has given impetus to the conduct of research into rel!fining the methods of building energy analysis, and thus to the development of this weather simulation model.
