Energy Code Field Studies

The U.S. Department of Energy (DOE) Building Energy Codes Program is conducting a series of research studies investigating energy code implementation in residential and commercial buildings. The goal of the study is to help document baseline practices, target areas for improvement, and quantify related savings potential. This information is intended to assist states in measuring energy code compliance and to identify areas of focus for future education & training initiatives.

Single-family Residential Buildings

Objective: Determine whether an investment in energy code education & training programs can produce a significant, measurable change in residential energy savings.

The study is comprised of three phases:

  1. Pre-Study: A baseline study to identify the energy use in typical single-family residential buildings in a given state and opportunities for improving energy efficiency
  2. Education & Training: Education, training & outreach activities targeting issues identified through the baseline study
  3. Post-Study: A second study to identify the change in energy use following the education & training activities

Through the project, DOE plans to establish a sufficient data set to represent statewide construction trends and detect significant changes in energy use resulting from education & training activities.

Participating States

The following states were selected to participate in the study (original DOE funding opportunity announcement):

STATE LEAD ORGANIZATION
Alabama Institute for Market Transformation (IMT)
Arkansas Southeast Energy Efficiency Alliance (SEEA)
Georgia Southeast Energy Efficiency Alliance (SEEA)
Kentucky Midwest Energy Efficiency Alliance (MEEA)
Maryland Maryland Energy Administration (MEA)
North Carolina Appalachian State University
Pennsylvania Performance Systems Development
Texas National Association of State Energy Officials (NASEO)

Several additional states have also initiated their own studies based on the DOE Methodology:

  • Delaware
  • Michigan
  • Missouri
  • Nebraska
  • Tennessee
  • Virginia
  • West Virginia

Methodology

Highlights from the updated methodology:

  • Results to be based on an energy metric and reported at the state-level
  • Focuses on individual code requirements within new single-family homes
  • Data confidentiality built into the experiment—no personal data will be shared
  • Designed around a single site-visit prioritizing key items
  • Designed with statistically significant results in mind

A detailed description of the study methodology is available below under Project Team Resources. Updated guidance will also be published upon completion of the study.

Multifamily Residential Energy Code Field Study

Objective: Measure the impact of energy codes on multifamily buildings and identify opportunities for savings through increased compliance.

Activities:

  • Identify and resolve challenges that are unique to multifamily construction
  • Update and tailor the residential methodology to accommodate multifamily buildings
  • Construct a representative data set across four target states {WA, OR, MN & IL}
  • Provide recommendations as to how multifamily buildings can be better represented through energy code training and other compliance-improvement programs

Impact: Compliance with building energy codes is key to ensuring intended savings to U.S. home and business owners. This project will develop an approach to accurately and affordably assess energy code compliance in multifamily buildings, as well as the savings available through increased compliance. This information is vital to utilities and others supporting compliance-improvement programs, providing the certainty they need to invest in increased efficiency through building code compliance. By developing the business case for energy efficiency, state and local governments will have additional tools to allocate their limited resources more wisely and effectively, thereby reducing energy bills and energy-related pollution.
