The best time to ensure a home's performance is before it is built. We work to bring residential design services to developers, builders and architects via programs and certification processes such as ENERGY STAR® Qualified Homes, LEED for Homes and Earth Advantage. We help ensure that home designs reflect appropriate technological and design advances and best practices—ultimately creating homes that use energy and resources wisely.

Bringing high performance to your design
We are energy-efficiency experts, with years of experience bringing better efficiency to single and multi-family homes. Our technical support staff has detailed knowledge of all aspects of energy efficiency, enabling you to use the superior design techniques when designing new residential construction. And our training expertise enables us to transfer key knowledge and techniques to you—quickly and easily.

Green and healthy focus
In New England, CSG offers both LEED for Homes and Earth Advantage certifications. A truly green home offers more efficient performance in terms of energy, water, and natural resources compared with a conventionally built home. It also creates less waste, and is healthier and more comfortable for the occupants. Benefits include lower monthly operating costs, reduced greenhouse gas and other emissions, and fewer indoor toxins such as volatile organic compounds, mold and mildew.
