This document presents a methodology for assessing baseline energy efficiency in new single-family residential buildings and quantifying related savings potential.
Beginning in 2014, the U.S. Department Energy (DOE) funded a series of multi-year residential energy code field studies to explore energy savings opportunities from enhanced code compliance. This report presents the final results across the three phases to assess whether the education and training activities successfully improved code compliance to achieve significant changes in energy use.
The purpose of this report is to document findings and final results from the Texas field study, including a summary of key trends observed in the field, their impact on energy efficiency, and whether the selected education and training activities resulted in a measurable change in statewide energy use.
The purpose of this report is to document findings and final results from the Pennsylvania field study, including a summary of key trends observed in the field, their impact on energy efficiency, and whether the selected education and training activities resulted in a measurable change in statewide energy use.
The purpose of this report is to document findings and final results from the North Carolina field study, including a summary of key trends observed in the field, their impact on energy efficiency, and whether the selected education and training activities resulted in a measurable change in statewide energy use.
The purpose of this report is to document findings and final results from the Maryland field study, including a summary of key trends observed in the field, their impact on energy efficiency, and whether the selected education and training activities resulted in a measurable change in statewide energy use.
The purpose of this report is to document findings and final results from the Kentucky field study, including a summary of key trends observed in the field, their impact on energy efficiency, and whether the selected education and training activities resulted in a measurable change in statewide energy use.
The purpose of this report is to document findings and final results from the Georgia field study, including a summary of key trends observed in the field, their impact on energy efficiency, and whether the selected education and training activities resulted in a measurable change in statewide energy use.
The purpose of this report is to document findings and final results from the Alabama field study, including a summary of key trends observed in the field, their impact on energy efficiency, and whether the selected education and training activities resulted in a measurable change in statewide energy use.

The available presentation slides focus on the residential provisions of the 2021 International Energy Conservation Code. The materials for this course were developed the DOE Building Energy Codes Program, and may be used for in-person training purposes.
The data (in this file or on this page) represents the data collected as DOE’s Residential Field Study[1] as of June 2016. Data is provided Microsoft Excel for 8 states – AL, KY, MD, NC, PA, TX, AR and GA. Additional states using DOE’s field study methodology, may be added in the future as data collection and analysis is completed.
This data file was reformatted and revised May 28, 2019, and again July 17, 2019.

The U.S. Department of Energy has provided funding for states to conduct residential field studies, with the purpose of identifying opportunities for energy code training & education in new construction. The participation of builders and local building departments is crucial in supporting this important activity. This Fact Sheet summarizes this field study.
Summary of the full technical brief which provides requirements for demand-responsive thermostats and water heaters that could be incorporated into model residential energy codes. It provides background on the benefits of these devices, impacts on the cost of construction, and model code language that can be plugged into the IECC or adapted into other energy codes.
Presentation slides from a 12/7/15 webinar that provided an overview of the U.S. Department of Energy Building Energy Codes residential field study, including methodology, sampling and current status. Data gathered across 10 states were reviewed, followed by a summary of initial findings that can inform future education & training activities. The potential savings associated with these activities were also be presented, which are of interest to government agencies, utilities and other entities.
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.
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.
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.
In early 2017, the Nebraska Energy Office expressed interest in evaluating the construction of new single-family homes in Nebraska using the US Department of Energy’s (DOE) low-rise residential evaluation methodology.1 As part of that methodology, Pacific Northwest National Laboratory (PNNL) was directed by DOE to analyze the data collected in Nebraska. This memorandum provides and discusses the results of PNNL’s analysis.
