What is going “green” worth in Washington home real estate? If you rehab a house to exacting energy and environmental standards, or install a solar-panel array on your roof, does your house command more when you sell?
If you seal up all the energy-leaking areas in your house, install a highly efficient heating and ventilating system, new windows and a long list of other green improvements, will a future buyer pay you a premium price for your efforts? A new study conducted by national appraisal experts says the answer most probably is yes — often tens of thousands of dollars more. Funded by the D.C. Department of Energy and Environment and assisted by the nonprofit Institute for Market Transformation, the study employed a sophisticated “paired sale” analysis of homes sold in the District between February 2013 and June 2015.
