comfort. If you
don’t provide it,
someone else will.

Rememberwhathappenedwith Indoor Air Quality (IAQ) services such as duct clean- ing? Even though HVACR
contractors are clearly the most knowledgeable providers of duct maintenance,
it wasn’t long before any business with
a vacuum system started offering duct
cleaning when consumers realized what
lurked inside their vents. Now energy
optimization is on the minds of commercial and residential customers.
If heating-cooling-and-ventilation contractors don’t respond, other businesses will.
In an effort to answer the many questions and concerns that our readers have
about building performance contracting and home performance contracting,
HVACR Business has invited several experts to contribute articles on these topics in 2012. This is the first of several articles that will be packaged and archived
together on HVACRBusiness.com.
In this article, Bill Spohn, CEO
and co-owner, Tru Tech Tools; and Jim
Bergmann, CTO and co-owner, Tru Tech
Tools, respond to some common questions that contractors have about building performance contracting and home
What is building performance
Building performance contracting
(BPC) — in its simplest sense — means
performing standard service and contracting work (construction, insulation,
windows, HVAC, electrical/lighting,
etc.) in existing and new buildings while
planning and coordinating how all of
these components and systems will interact with each other throughout all
stages of the job, and ultimately, while in
systems — their customers save on energy
costs as they enjoy increased comfort and improved IAQ. Additionally,
this approach is based on
science and precision measurement, so both contractors and
customers can have confidence in

issues in new construction.
