Ask an insulation contractor, a heating tech, and a window salesperson the best way to warm up a cold room, and you may get three different answers. As a building performance contractor, we take a whole-house perspective to assess the problem's causes and propose the most effective solution. Understanding the "house as a system" also allows us to solve problems like chimney back-drafting that arise from interactions between the building's shell and mechanical systems.

As building scientists, we use a diagnostic approach to problem solving. Experience and observation, coupled with pressure diagnostics, infrared imaging, and combustion analysis, allow us to diagnose and correct the most challenging building performance problems.

The difference between an average house and a high-performance house often comes down to a contractor's willingness to "sweat the small stuff" that the customer never sees like air sealing, insulation, and ductwork.

The core concept is an emphasis on measurable results from performance testing. Performance testing also assures the customer that they have a safe, comfortable, durable, and efficient building when the work is completed.
