Document type: Reports and Studies
Publication Date: May 2017
Page Focus: Residential

A research project in the Commonwealth of Pennsylvania identified opportunities to reduce homeowner utility bills in residential single-family new construction by increasing compliance with the state energy code. The study was initiated in October 2014 and continued through July 2015. During this period, research teams visited 171 homes during various stages of construction, resulting in a substantial data set based on observations made directly in the field. Analysis of the data has led to a better understanding of the energy features present in homes, and indicates over $2.7 million in potential annual savings to Pennsylvania homeowners that could result from increased compliance with the 2009 International Energy Conservation Code (and equivalent compliance options). Public and private entities within the state can use this information to justify and catalyze future investments in energy code training and related energy efficiency programs.

Pacific Northwest National Laboratory (PNNL) conducted a series of cost effectiveness analyses for the U.S. Department of Energy (DOE), covering the 2009 and 2012 editions of the International Energy Conservation Code (IECC) for new single and multifamily homes. The evaluations were performed against a 2006 IECC baseline, taking state-specific code amendments into consideration. These reports outline the results of these analyses, including a National Cost Analysis and Cost Analyses for selected states.
