许多公用事业和政府计划存在，以促进住宅建筑的能源效率（EE）。虽然计划成功地降低了每平方英尺的能源使用强度（EUI），但就减少总能源消耗而言，它们并不一定促进节约。使用统计分析和数据挖掘技术，我们研究了家庭规模，电力和天然气EUI之间的关系，邻里水平的社会经济属性之间类似的洛杉矶县（LAC）的130万单户住宅。我们观察到，在1900年至2010年建造的房屋中，按建筑年份计算的房屋面积中位数的增长速度超过了EUI下降的60%。从这些观察到的趋势得出的蒙特-卡罗抽样程序的结果表明，过去的历史能源节约在LAC内，由于国家规定的EE政策，可以等效地通过限制新建房屋的规模增长来实现。这些研究结果具有重大意义的设计未来的节能政策在不断增长的城市地区。
Many utility and government programs exist to promote energy efficiency (EE) in residential buildings. While programs have succeeded in reducing per square foot energy usage intensity (EUI), they do not necessarily promote conservation, in terms of reduced total energy consumption. Using statistical analysis and data mining techniques, we examined relationships between home size, electricity and natural gas EUIs, and neighborhood level socio-economic attributes among similar to 1.3 million single-family homes in Los Angeles County (LAC). We observed that among homes constructed between 1900 and 2010, the growth in median home size by construction vintage year has outpaced combined EUI reductions by 60%. Results of a Monte-Carlo sampling procedure derived from these observed trends indicate that past historical energy savings within LAC, attributable to state mandated EE policies, could have been equivalently achieved by constraining growth in the size of newly constructed homes. These findings have significant implications for the design of future energy conservation policies within growing urban areas.
