Performance comes home for Steve Thomas.

Describes the energy efficient retrofit of a residential building following a home performance assessment. Home performance contractors were able to save the owner 40% in annual heating costs with an insulation upgrade, a heating and hot water system replacement and air sealing in the 200 year old house. As part of a promotion exercise for the new Home Performance with Energy Star initiative in New York, the house was the demonstration site for a TV and video production. It went through rigorous testing that included blower door diagnostics, an infrared thermal scan, combustion safety tests and computer modelling. The test's results determined the home's potential energy savings and were used to help size the new heating system.
