Two old homes with new energy-efficient technology were unveiled Wednesday in Las Vegas.
The two homes are owned by the city of Las Vegas and have been retrofitted with energy-saving upgrades. The effort is part of the Department of Energy’s Building America Retrofit Alliance and a program by the Nevada Energy Star Partners-GREEN Alliance. One home reduced its energy use by at least 50 percent.
"It was an energy hog home which gave us a lot of opportunity to improve it. It leaked every bit of air-conditioning air that we put into it,” President of Nevada Energy Star Partners-GREEN Alliance Annette Bubak said. “We added foam insulation up against the roof line so it was like a cocoon.”
