This is great news, proving that it’s cost-effective to make existing buildings more energy efficient. The expected payback time is only three years -after that, it’s all icing (and reduced energy use, emissions, etc.) Buildings are the greatest users of energy in the US – everyone can do their part by adding insulation, sealing cracks, replacing old windows, etc. You don’t need to put $30,000 in solar panels on your roof to make a difference.
