    Why Choose CSG?

  • Program experience—We know how to introduce, manage, and monitor large-scale new construction programs that transform the marketplace for improved new construction practices—and increase the value of homes. We help energy program administrators reach the building professionals who can make energy efficiency part of their construction practices.

  • Comprehensive building performance testing—We test all aspects of a home-insulation levels, air leakage, duct leakage and room-by-room airflow testing, mechanical ventilation needs, and carbon monoxide testing.
