Nation’s Oldest Net Zero Home in the Works

CodeWatcher Roswell Georgia

A home in Roswell, Ga., is on track to become the first 1840s solar-powered, net zero energy house in the country.

A historic home could become a model for retrofitting important old buildings to make them lighter on the planet and less expensive for municipalities to maintain.

According to an article in the Atlanta Business Journal, The City of Roswell purchased Mimosa Hall, initially built around 1840, as well as its nine acres of gardens and woods last August for $2.95 million and now the Friends of Mimosa Hall and Gardens organization is proposing to make the historic building the oldest “net zero” building in the United States.

Sustainable features include the installation of thin solar panels and Sonnen batteries to store excess energy.

The article says:

In all, the renovation will cost about $135,000, but du Boise said she expects that about half of the total cost will be paid for by federal incentives, credits, donated and discounted services and products.

Du Boise predicted the improvement costs would pay for themselves within one or two years thanks to the energy savings.

“We want to keep and maintain all the energy that we generate,” said Gibson, adding that Mimosa Hall would remain on the power grid. “The city would still have an energy bill – about $30 a month.”

The project is important because new building science and advancements in PV technology and other alternative energy solutions means energy-intensive older buildings can shrink their environmental footprint as well as new buildings.
