In 1978, California adopted building codes designed to reduce the energy used for temperature control. Using a rich dataset of hourly electricity consumption for 158, 112 houses in Sacramento, we estimate that the average house built just after 1978 uses 8% to 13% less electricity for cooling than a similar house built just before 1978. Comparing the estimated savings to the policy's projected cost, our results suggest the policy passes a cost-benefit test. In settings where market failures prevent energy costs from being completely passed through to home prices, building codes can serve as a costeffective tool for improving energy efficiency.

住宅建筑规范确实节能：来自每小时智能电表数据的证据

1978 年，加利福尼亚州采用了旨在减少用于温度控制的能源的建筑规范。使用萨克拉门托 158、112 所房屋每小时耗电量的丰富数据集，我们估计 1978 年之后建造的平均房屋用于冷却的电力比 1978 年之前建造的类似房屋少 8% 至 13%。保单的预计成本，我们的结果表明该保单通过了成本效益测试。在市场失灵阻止能源成本完全转嫁给房价的情况下，建筑规范可以作为提高能源效率的具有成本效益的工具。
