Habitat for Humanity, which provides shelter for 2 million people, is now not only affordable but, in Nashville, it's environmentally sound too.
Ralph Knauss of Habitat for Humanity of Greater Nashville told CBN News that his crews are constructing "greener" homes to help homeowners save money on their utility bills.
He explained that behind each "brick foundation there's a 2-inch foam insulation area" which provides extra insulation in the cooler months.
His builders also use Energy Star appliances and low-flow fixtures that allow less water to travel through the opening while providing the same adequate water pressure.
Knauss said the extra guidelines and meticulous building processes are worth it despite the fact that going green costs several thousand extra per home because Habitat's homeowners are the true beneficiaries.
Habitat Homeowner, Casey Greer, said her energy-efficient Habitat home saves her hundreds of dollars a month on electricity.
She used to pay $350 a month for electricity and now only pays around $56.
Greer said the savings have given her stability and security since she lost her job shortly after she and her two daughters moved in.
Last year, Habitat for Humanity built close to 5,000 homes and it is the sixth largest residential builder in the nation.
The organization keeps its costs low through low overhead thanks to volunteer hours, contributions and interest-free mortgages.
The Nashville chapter hopes their initiative to go green will soon spread nationwide.
