Abstract

Building energy code compliance is the critical link between the efficiency specified in energy codes and actual energy savings. A research project aiming to identify opportunities to reduce energy consumption in residential single-family new construction by increasing compliance with the building energy code was conducted in several states of the United State. The study was comprised of three phases; (1) a baseline study to document typical practice and identify opportunities for improvement based on empirical data gathered from the field; (2) an education and training phase targeting the opportunities identified, and; (3) a post-study to assess whether a reduction in average statewide energy use could be detected following the education and training phase. We proposed a novel methodology, based on large scale building energy simulation inferred by limited field data, to assess performance of a large population of homes. This methodology addresses two issues that impact existing methodologies: a lack of energy performance metrics and the cost of field surveys. This paper presents the methodology, and findings and results of this study. Overall, the training and education play a recognizable role in improving compliance with building energy codes.
