Bruce Glanville, the Home Performance Professional, is the best home and building makeover expert for homeowners,  contractors and utilities in the Southeast. He was an early pioneer in the field of the effects of building science on good health. He has managed multiple projects that have won LEED and Energy Star Certification. He has tested nearly a thousand homes.

He achieved the first LEED Gold Certifications for Low Income Housing in the US. He ran  a City of Knoxville program which renovated low-income homes and successfully reduced energy costs by 37%.

Since founding On Earth Energy Group in 2006, Bruce has become the “go-to” consultant for those who care about applied building science, from TVA to Oak Ridge National Labs to Glasgow Electric, from government agencies to non-profits, from architects and developers to alternative energy providers.

He helped TVA launch their EnergyRight Solutions (now eScore) program by personally assessing over 300 homes in 10 months. He consulted with Elizabeth Eaton architects on a 30-unit senior citizens housing project which received a LEED Platinum certification.

He completed a baseline and post retrofit verification in Kentucky for the Phase 1 Glasgow Electric Plant Board/TVA Residential Deep Home Energy Retrofit Grant, which achieved an average energy reduction of 39% for the 12 pilot project homes.

Bruce conducted building analyses for DNV/GL by testing and verifying over 400 private homes throughout East Tennessee. These verifications confirmed TVA’s In-Home Energy Evaluation (now eScore) retrofit results.

He provided Green Rater services for 48 successful LEED for Homes certifications for new home construction. This includes the first 7 LEED Gold Low-Income homes in the US.

Bruce lectures on building science and consults with the University of Tennessee Department of Arts and Architecture. In 2014, he served as the President of the Technical Society of Knoxville, TN.

Bruce lives with his wife Melissa, son Thomas and daughter Marena on his family farm in East Tennessee.
