My name is Jon Haehnel and I have been testing and inspecting residential and commercial buildings for the last 7 years. My business, Zero By Degrees LLC is located in Fairlee, VT. You may have seen me as a guest consultant on the program “The Green Makeover: A Video Guide to Greening Up Your Business” shown on public television. Between my testing experience, the training classes I teach, and my background as a high school physics teacher I know how to take the complexity of building envelope theory and break it down into simple blocks of knowledge. I have found in my work that there are a lot of people out there, like you, that want to save money and conserve our natural resources, but it takes insider knowledge to make the best choices. I have distilled that insider knowledge down to the critical points that you can learn and use quickly.
