Single-family Residential Buildings
Objective: Determine whether an investment in energy code education & training programs can produce a significant, measurable change in energy savings for single-family residential buildings.
The study is comprised of three phases:
- 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
- Education & Training: Education, training & outreach activities targeting issues identified through the baseline study
- 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):
Several additional states have also initiated their own studies based on the DOE Methodology (study results are available where linked):
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

Multifamily Residential Buildings
Objective: Validate the impact of building energy codes in low-rise multifamily buildings and identify opportunities for increased energy that can be addressed through workforce education & training programs.
Activities
- Develop a field-based methodology which can be implemented in low-rise multifamily buildings
- Identify and resolve challenges that are unique to multifamily construction
- Construct an empirical data set across four target states {WA, OR, MN & IL}
- Examine envelope air tightness testing protocols and challenges in the multifamily sector
- Provide recommendations as to how multifamily buildings can be better represented through energy code training and other compliance-improvement programs
