Summary of the findings of the 2003 Residential New Construction Baseline Study conducted by Itron, Inc. under Pacific Gas & Electric (PG&E) management.1 KEMA-Xenergy conducted the on-site surveys. The RNC baseline study investigates energy efficiency in newly constructed single family homes throughout California. The study’s primary purpose is to provide information to residential new construction (RNC) program managers across the state, thereby allowing them to assess and address the effect of recent energy code changes on these programs.

These analyses evaluate the cost-effectiveness of the prescriptive path of the 2015 edition of the International Energy Conservation Code (IECC), relative to the 2012 and 2009 IECC for all 50 states and the District of Columbia. The analysis covers one- and two-family dwelling units, town-homes, and low-rise multifamily residential buildings covered by the residential provisions of the 2015 IECC.
