Dave Keefe, Energy Consultant with the Vermont Energy Investment Corporation, has spent the last 30 years working as both a contractor and teacher to make homes perform better. He has provided more than 1000 technical training sessions to both professionals and homeowners, including building science, energy codes, home energy ratings, low-income weatherization, diagnostic techniques, and installation methods. Dave is known as a personable and effective trainer, and in 2011 was named by ACI Inc as one of “the 25 most instrumental people in building the home performance industry”. He can also brew (according to Andy) “a fairly decent smoked porter”.
