This R markdown file reads in a data file posted on the Oberlin College web site and uses it to calculate various statistics presented in our 2018 Energy and Buildings paper entitled, "Energy Performance of LEED-Certified Buildings from 2015 Chicago Benchmarking Data."本R Markdown文件读取了发布于欧柏林学院（Oberlin College）官网的数据集文件，并基于该文件计算了我们2018年发表在《能源与建筑》（Energy and Buildings）期刊上、题为《基于2015年芝加哥基准数据的LEED认证建筑能源绩效》的论文中所呈现的各项统计数据。
