The State of Utah recently purchased an E-60bx thermal camera for my use in energy efficiency training and studies. Using a thermal camera for building diagnostics identifies many areas where energy efficiency can be improved. "The cheapest, cleanest, most sustainable energy is energy conserved"
This is an organization in Massachusetts that helps homeowners and businesses lower their energy costs and consumption. We bought a hundred year old house a little over a year ago and had them do an energy audit. For a small fee, they performed various tests on our home's energy efficiency and made several retrofit solutions for no additional charge - new CFL bulbs throughout the house, low-flow aerators and shower head, and various draft sealing measures. As a result of the audit we were able to secure a 0% loan for a new high efficiency furnace and tankless hot water heater.
