The Livermore family of Gloucester, Massachussetts, were tired of living in an outdated, costly to run home.
Now they have renovated their 1970s house into a home that produces more energy than it uses.
It's the first remodeled in the state to achieve Net Zero, and one of a growing number across the country.
“Our main goal was to lower our energy bills and take responsibility for our carbon footprint.” said John Livermore, founder of Healthy Home Healthy Planet. “We now produce more energy than we need and we’ve improved our quality of life. It’s a model any homeowner can use.”
Homes that produce more than they consume are called Net Positive Energy Homes. In the first year after the renovation, the home generated 86% more electricity than it used, resulting in a net profit. Completed on a budget of $60,000 the project’s return on investment (ROI), including the value of all the non-energy benefits, was over 10% — surpassing recent stock market returns.
The Livermore renovation demonstrates that homeowners can be power producers. With 2.8 million homes in Massachusetts, and 134 million homes nationally, there is abundant opportunity to make a positive difference. “With the huge untapped potential for deep energy savings in existing residential buildings, the Livermore house project presents a viable model on a moderate budget,” said energy engineer, Marc Rosenbaum, P.E.
