城市越来越多地采用能源政策，通过数据透明度减少信息不对称和知识差距，包括能源披露和对现有建筑的强制性审计要求。虽然这种审计给建筑物业主带来了不小的成本，但他们的能源使用影响没有得到经验上的评估。在这里，我们使用2011至2016年间约4,000栋建筑的详细审计和能源数据，研究了大规模强制性审计政策-纽约市第87号地方法-对建筑能源使用的影响。在这一特定的政策背景下，遵守年是随机分配的，这为探索审计效果提供了一个独特的机会，而不存在自愿审计政策研究中发现的自我选择偏见。我们发现，多户住宅建筑的能耗降低了约-2.5%，写字楼的能耗降低了约4.9%。结果表明，强制审计本身不足以激励人们按照实现全市碳减排目标所需的规模投资于能源效率。尽管越来越多的城市正在考虑强制建筑能源审计，但它们对建筑能源使用的影响尚不清楚。使用来自纽约的数据，Kontokosta等人。估计当地第87号法律规定的建筑物能源审计对减少能源使用的贡献程度。
Cities are increasingly adopting energy policies that reduce information asymmetries and knowledge gaps through data transparency, including energy disclosure and mandatory audit requirements for existing buildings. Although such audits impose non-trivial costs on building owners, their energy use impacts have not been empirically evaluated. Here we examine the effect of a large-scale mandatory audit policy-New York City's Local Law 87-on building energy use, using detailed audit and energy data between 2011 and 2016 for approximately 4,000 buildings. This specific policy context, in which the compliance year is randomly assigned, provides a unique opportunity to explore the audit effect without the self-selection bias found in studies of voluntary audit policies. We find energy use reductions of approximately -2.5% for multifamily residential buildings and -4.9% for office buildings. The results suggest that mandatory audits, by themselves, create an insufficient incentive to invest in energy efficiency at the scale needed to meet citywide carbon-reduction goals.Although more cities are considering mandatory building energy audits, their effect on energy use in buildings is not clear. Using data from New York, Kontokosta et al. estimate the extent to which Local Law 87 mandating building energy audits has contributed to a decrease in energy use.
