State-level analysis results behind the DOE Status of State Energy Code Adoption Map for residential buildings.

A research project in the state of Tennessee 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 September 2017 and continued through July 2018.  Analysis of the data has led to a better understanding of the energy features present in homes and indicates over $2.5 million in potential annual savings to Tennessee homeowners that could result from increased code compliance.

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.

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.

A research project in the Commonwealth of Virginia 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 August 2017 and continued through May 2018. During this period, research teams visited 138 homes during various stages of construction, resulting in a substantial data set based on observations made directly in the field.
