These analyses evaluate the cost-effectiveness of the prescriptive path of the 2018 edition of the International Energy Conservation Code (IECC), relative to the 2015 IECC with amendments for all 50 states and the District of Columbia. The analysis covers one- and two-family dwelling units, townhouses, and low-rise multifamily residential buildings covered by the residential provisions of the 2018 IECC.
These analyses evaluate the cost-effectiveness of the prescriptive path of the 2009 and 2012 editions of the International Energy Conservation Code (IECC), relative to the 2006 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 2009 and 2012 IECC.

From August 1997 to September 1999, one hundred new Arkansas homes were evaluated in two areas in the state where there was significant building activity in order to determine the energy performance of current building practices. One of the positive findings was that homes are now being built significantly tighter than a few years ago. Homes built in the early to in.id 1990's were experiencing an average of 0.5 natural air changes per hour (NACH), an acceptable level considered normal for new construction Only 24 homes in this evaluation had leakage rates exceeding 0.4 NACH; the majority of homes (58 percent) had leakage rates of 0.35 and under.
A research project in the State of Arkansas investigated the energy code-related aspects of unoccupied, newly constructed, single family homes across the state. The study followed a DOE-prescribed methodology, which allowed the project team to build an empirical data set based on observations made directly in the field.
PNNL evaluated the cost effectiveness of the changes in the prescriptive and mandatory residential provisions of the 2021 edition of the IECC, compared to those in the prior edition, the 2018 IECC.
