Our time spent in the field, working with HVAC engineers, architects and general contractors has exposed us to the right and wrong ways to approach energy efficiency design for residential and commercial construction. Additionally, our certifications with the Building Performance Institute (BPI) and the Energy Star HERS program provide us with a foundation of basic principles necessary to provide guidance for your next project. Measured performance through the use of diagnostic equipment is the other essential component to a successful design / build. Thermal imaging, heating & cooling modeling and air leakage testing are just some of the methods that we use to verify performance. You cannot reach your energy efficiency goals without the ability to measure efficiency performance.
