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.

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.

A research project in the state of Montana 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 2018; data collection began in June 2018 and continued through September 2018. During this period, the project team visited 125 homes at various stages of construction, resulting in a data set based on observations made directly in the field.

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.

Publication Date:

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.

Publication Date:

A research project in the state of Idaho identified opportunities to reduce homeowner energy costs in residential single-family new construction by increasing compliance with the current state energy code. The study was initiated in January 2018; data collection began in March 2018 and continued through June 2018. During this period, research teams visited 127 homes during various stages of construction, resulting in a collection of data based on observations made directly in the field.

Publication Date:

A research project in the State of Georgia 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.

This report is focused on the analysis of collected data in support of the development of an updated methodology to measure the impact of energy codes on commercial buildings and identify opportunities for savings through increased compliance. The primary goal was to analyze the data collected during the field study and determine the actual energy cost impact of each measure in a non-compliance situation. The energy impact results allowed for ranking the measures to identify which have the highest potential for lost savings.
