A research project in the state of Alabama 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 March 2014, and continued through May 2014. During this period, research teams visited 134 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 nearly $1.3 million in potential savings to Alabama homeowners that could result from increased code compliance. 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.

A research project in the State of Arkansas 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 May 2015 and continued through October 2015. During this period, research teams visited 226 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 $300,000 in potential annual savings to Arkansas homeowners that could result from increased code compliance.

A research project in the State of Georgia 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 April 2015 and continued through November 2015. During this period, research teams visited 216 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 $3 million in potential annual savings to Georgia homeowners that could result from increased code compliance.

Pacific Northwest National Laboratory analyzed the relationship between the Residential Energy Services Network (RESNET) Home Energy Rating System (HERS) Index and the traditional simulation-based Performance Path used in the International Energy Conservation Code (IECC). The analysis evaluates, for a single-family residence with various characteristics, the ranges of HERS Index values that would imply compliance with the 2012 IECC Performance Path. Several building characteristics considered likely to result in quantifiable differences in the outcomes of the two approaches, or otherwise believed to be of interest to code developers and policy makers, are considered in the analysis.

A research project in the Commonwealth of Kentucky 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 April 2015 and continued through August 2015. During this period, research teams visited 140 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 $1,200,000 in potential annual savings to Kentucky homeowners that could result from increased code compliance.

A research project in the state of Maryland investigated energy code-related aspects of residential single-family new construction. The study was initiated in January 2015 and continued through July 2015. During this period, research teams visited 207 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 $1.5 million in potential savings to Maryland homeowners that could result from increased code compliance. 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.

A research project in the State of North Carolina 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 January 2015 and continued through September 2015. During this period, research teams visited 249 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 $1.5 million in potential annual savings to North Carolina homeowners that could result from increased code compliance.

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.

A research project in the state of Texas 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; data collection began in March 2015, and continued through October 2015. During this period, research teams visited 133 homes in 30 counties in and around Houston during various stages of construction, resulting in a substantial data set based on observations made directly in the field. Stakeholders in the state agreed that these 30 counties represented the levels of energy codes and enforcement seen across the state. Analysis of the data has led to a better understanding of the energy features present in homes, and, when extrapolated across the entire state, indicates over $16 million in potential annual savings to Texas homeowners that could result from increased code compliance. Public and private entities within the state can use this...
