Green buildings are designed and built in such a way that they have a reduced impact on the environment.

• Energy efficiency - Buildings and homes use as little energy as possible, relying on renewable energy when feasible.
• Resource efficiency - Renewable and recycled resources are used for construction materials. Landscaping and constructive use of natural light conserves resources. Water conservation products and practices are incorporated.
• High indoor air quality - Ventilation systems, less toxic building materials, and low VOC emission furnishings and finishes contribute to a healthier indoor environment.

Several local builders use green building techniques such as air sealing, advanced framing methods, exterior foam sheeting, ductless heat pumps, and mono forms for building foundations.

Radon gas

Radon is a colorless, odorless gas that occurs naturally in decaying rock. Clark County has been designated as a high radon potential zone, but that does not mean that you have radon in your home. One house can test safe and the house next door can test high due to the structure of the rock formations in the ground below each house.

Since 2006 new homes and additions have been required to have a passive radon vent installed. Houses built before that date most likely have no radon vents. In the effort to tighten homes to save energy this may cause radon to be trapped inside. Radon is the second leading cause of lung cancer.

Testing is the only way to find out if your home contains radon. To find a test kit, contact your local hardware store, home improvement center, or go online. You can also contact a radon mitigation company in your area to test and advise you about radon levels in your home.
