Smell the green.. Below is my interview with Annette Osso, the President of Virginia Sustainable Building Network (VSBN). She talks about the huge opportunity for housing. 130 million homes – yes, big M, that is – potentially is available for retrofit. Not only for retrofit, energy efficiency kind of business alone, but also the financing side of it. I have other report available for other green opportunities that I will post it here sometime this week. So check back for updates.
