A primary goal of this public-private partnership was to create more jobs within Clark County’s building community. The Clark County commissioners adopted the National Green Building Standard as a voluntary code to help residential builders obtain a uniform set of green guidelines to help customers seeking more efficient and healthy homes. Learn why green building is better!

We invite you to explore the planet and discover ways to improve the indoor air quality of your home, reduce your energy expenses and protect your investment!
