Home buyers are now looking for homes that are energy efficient and green. Having documented proof, from a third party verifier, gives you the credibility that ensures you have taken the extra steps to make your homes energy efficient and green. Your home buyers will enjoy the comfortable, energy efficient and green home. This can give your home buyer a peace of mind, and can reduce your warranty call backs. As a builder, you are creating a reputation for quality and energy efficiency. CGE is accredited to perform testing and certification for several energy efficiency and green programs.

ENERGY STAR Rated Homes -

To earn the ENERGY STAR, a home must meet strict guidelines for energy efficiency set by the U.S. Environmental Protection Agency. These homes are at least 15% more energy efficient than homes built to the 2004 International Residential Code (IRC), and include additional energy-saving features that typically make them 20–30% more efficient than standard homes.

DOE's Builders Challenge -

As a participant in the Builders Challenge, you can take advantage of the use of the EnergySmart Home Scale (E-Scale), as well as marketing and technical resources provided through the initiative. In addition, a design competition will make high performance home plans more readily available and annual awards will recognize and reward participation.

The image below is a representation of what we have found in current building construction. Which can cause problems within the building envelop leading to potential customer call backs. Choosing either a building program or implementing your own third party inspected quality assurance program, CGE can help.

These IR images where taken with an outside temperature of approx 35F, with the sun heating the external wall.  The insulation was not installed to manufacture's specifications, and the air seal installation left gaps in the bottom plate and wall stud. This could lead to potential air infiltration problems and customer call backs. This is the type of workmanship we are typically finding on jobsites.
