The residential building sector consumes a large amount of energy and is recognized as a high potential area where urban energy consumption and carbon emission can be reduced. To reduce the residential energy consumption, relevant policies and measures have been formulated in different places. However, due to the lack of adequate information in the process of policy formulation, the effectiveness of most energy-saving policies for residential buildings seems to be unsatisfactory. Although previous studies have analyzed the energy consumption for a single building or for the whole construction industry at the national level, few of them investigated the life-cycle energy consumption of residential buildings at the city level. Since municipal governments are the key implementers for the reduction of urban energy consumption, a city-level analysis on the energy consumption of residential buildings is highly needed for the policy making. To fill the research gap, this paper develops a life-cycle dynamic simulation model to fully reveal the characteristics of energy consumption of residential buildings at the city level. This easy-to-use model is validated by a case study of Beijing, which demonstrates its applicability and capability to help analyze multiple indicators of residential energy consumption and the dynamic trends of these indicators for municipal governments. Furthermore, the model can be used under the condition of limited input data, and can provide the situation analysis and simulation results of energy consumption of urban residential buildings for facilitating the policy making by municipal governments.
住宅建筑部门消耗大量能源，被认为是城市能源消耗和碳排放减少的高潜力领域。为了减少住宅能源消耗，不同地方都制定了相关政策和措施。然而，由于在政策制定过程中缺乏足够的信息，大多数住宅节能政策的效果似乎并不理想。尽管之前的研究已经分析了单个建筑或整个建筑行业的能源消耗，但很少有研究在城市层面上调查住宅建筑的生命周期能源消耗。由于市政府是减少城市能源消耗的关键执行者，因此非常需要对住宅建筑的能源消耗进行城市层面的分析，以制定政策。为了填补研究空白，本文开发了一个生命周期动态模拟模型，以充分揭示城市层面住宅建筑能源消耗的特点。该模型通过对北京市的案例研究进行了验证，证明了其适用性和能力，可帮助分析住宅能源消耗的多个指标及其动态趋势，为市政府提供决策支持。此外，该模型可以在输入数据有限的情况下使用，并能够为市政府提供城市住宅建筑能源消耗的情况分析和模拟结果，以促进政策制定。
