The Roswell City Council has approved the installation of solar panels and other energy-saving measures for Mimosa Hall, making the historic house what officials called a “net zero” building in terms of energy use.
The retrofit is expected to cost about $135,000. The city agreed to pay the Friends of Mimosa, the nonprofit organized to help preserve the property and raise funds for it, $35,990 to go toward the roof replacement and solar installation.
The building will get solar panels and a solar thermal system integrated with the roof. The panels will connect to batteries that will store excess solar energy for nighttime and rainy day use.
The city paid $2.95 million last summer to buy Mimosa Hall and its nine-acre site. The house dates to 1840 and had been on the “Places in Peril” list of the Georgia Trust for Historic Preservation. A new roof was needed, and the city budgeted funds for it.
