Commitment to Excellence  


Cornerstone Inc - A Certified Green Builder


Cornerstone Inc. is a proud builder of ENERGY STAR labeled homes, NAHB GREEN Built homes, & Inland Northwest BUILT GREEN homes. 

This means your Cornerstone home is less expensive to operate, healthier, and built with quality.

ENERGY STAR Homes                                                                                    

ENERGY STAR qualified products and practices help you save money and reduce greenhouse gas emissions by meeting strict energy efficiency guidelines set by the U.S. Environmental Protection Agency and U.S. Department of Energy. The ENERGY STAR label also designates superior energy performance in homes and buildings.

ENERGY STAR homes are as much as 30% more energy efficient than homes simply built to code standards. The benefits of an ENERGY STAR home are many.

Enhanced Comfort

Enjoy a home with even temperatures throughout - warmer in winter, cooler in summer - and free from drafts. Tightly-sealed ductwork, high-performance windows and properly installed insulation all contribute to making your new home more energy efficient.

Healthier Indoor Air

Performance-tested ductwork helps keep the air inside your home clean by reducing the possibility of drawing unwanted air from your home's attic, basement, crawl spaces, and garage. This reduces the amount of dust in your house, so you don't have to dust as often and the air you breathe is cleaner.


ENERGY STAR homes cost less to own and live in than homes just built to the building code. Monthly energy bill savings typically outweigh any incremental mortgage costs of ENERGY STAR and get better with time. For every dollar the utility company raises the cost of energy, an Energy Star home owner only sees close to 70% of this. This is truly leveraging your investment. These homes keep more money in your wallet and offer the potential for higher resale value, making an ENERGY STAR home a good investment and a smart choice.

Peace of Mind

Relax knowing your home has been inspected and certified by an independent third party to meet ENERGY STAR's standards. Simplify the numerous energy efficiency choices in the new home buying process by choosing one that has earned the trusted ENERGY STAR label.

Better Future

Choose a home that uses less energy, and you'll help contribute to a healthier environment and a better future for your family and friends. Each ENERGY STAR home keeps 8,513 pounds of Carbon Dioxide out of the atmosphere each year. 


NAHB Green Homes & Inland Northwest Built Green Homes                    

The NAHB Green Building program (Idaho) and the Inland Northwest Green Built program (Washington) are regional  programs that take the green built process one step further than ENERGY STAR label homes to certify that your home is built to their green home standards.  Cornerstone is a certified member of both programs.
