Measuring the Baseline Compliance Rate for Residential and Non-Residential Buildings in Illinois Against the 2009 International Energy Conservation Code
The goals of this study were threefold: 1) Provide feedback to the BECP on the implementation of the BECP protocol 2) Develop a preliminary pattern/range of the existing compliance rates of newly constructed residential dwellings and commercial buildings based on jurisdictions in Illinois that have adopted the building energy codes and 3) Identify areas where home performance and codes training and education activities could be improved or refocused. Measurements of a small sample set (10) of commercial buildings were also taken. Due to the insignificance sample size, a commercial compliance rate is not reported here.
