Test for radon
In high risk areas, rough in a vent during construction
RadonColorless, odorless, short-lived radioactive gas that can seep into homes and result in lung cancer risk. Radon and its decay products emit cancer-causing alpha, beta, and gamma particles. is a radioactive gas that occurs naturally in some types of rock, well water, and some stone and concrete. Radon causes lung cancer. It can quickly build to unhealthy levels in insulated buildings with large areas in contact with the ground. A venting system that picks up radon from beneath the basement slab is relatively easy to do during construction, more difficult after the fact. Maps showing radon risk for the U.S. are available on the EPA’s web site. If you are in high-risk area, test the soil before starting construction.
Green points
LEED for HomesLeadership in Energy and Environmental Design. LEED for Homes is the residential green building program from the United States Green Building Council (USGBC). While this program is primarily designed for and applicable to new home projects, major gut rehabs can qualify.
: Following EPA recommendations for radon-resistant construction is a prerequisite in high-risk areas; 1 point for using the techniques in other areas (EQ 9).
NGBSNational Green Building Standard Based on the NAHB Model Green Home Building Guidelines and passed through ANSI. This standard can be applied to both new homes, remodeling projects, and additions.
/ICC-700: Up to 15 points for an active radon system (902.3).
