Over the past decade, a number of studies have been conducted that demonstrate the market case of energy-efficient homes and apartments. These studies have shown sale and re-sale price premiums ranging from 2% to 8% in most markets for rated, energy-efficient homes, including ENERGY STAR certified homes.
In the largest national study to date, economists from the government-backed enterprise Freddie Mac found a 2.7% average sales price premium for rated energy-efficient single-family homes, with more efficient homes selling for a 3-5% premium compared to less efficient rated homes (2013-2017).

Several other local/regional studies have also been published linking energy efficiency to higher market valuations, including:
- ENERGY STAR certified homes in Maryland sold from 2012-2015 were found to have a 2-5% sales price premium. Source
- In Austin-Round Rock, TX, ENERGY STAR certified homes sold from 2009-2016 had an average price premium of 6%. Source
- In specific markets in Oregon, Idaho, and Washington, price premiums for ENERGY STAR and other certified energy-efficient homes of up to 8% were found in a 2015 study. Source
- A 2013 study of certified homes in California found an average sales premium of 2.1%. Source
