NGBS Green Single-Family Home Certification

The National Green Building Standard (NGBS) provides practices for the design, construction, and certification of new green single-family homes, including:

  • single-family homes

  • townhouses

  • duplexes

Builders seeking NGBS Green certification for their homes have two options. Homes can earn Bronze, Silver, Gold, or Emerald certification, depending on the number of green practices successfully incorporated into its design and construction. This option applies for all versions of the NGBS. Alternatively, homes can earn the Certified level by following the streamlined single-family certification path in the 2020 NGBS. In order to be eligible for the Certified path, homes must successfully incorporate all applicable practices in Chapter 12 of the 2020 NGBS.

Existing single-family homes can also attain one of the four certification levels (Bronze, Silver, Gold, Emerald) when remodeling in compliance with the NGBS.

We serve as the bridge connecting consumers with manufacturers, architects, builders, and designers in order to create healthier homes. 


During her groundbreaking work on Eco Manor—the first LEED gold certified private residence—Wellness Within Your Walls founder Jillian Pritchard Cooke discovered that consumers and professionals both needed accurate information on how to reduce toxins in the interior environment.

A subsequent cancer diagnosis become the catalyst for turning that expertise into a passionate commitment to creating healthier living environments by reducing toxins.  Jillian shared her passion, grew her commitment and brainstormed with family, friends, co-workers and experts in the building and home furnishings industries, and soon Wellness Within Your Walls was born.

WWYW allows us all, whether in our roles as consumers or producers of home products and services, to easily make healthier, responsible choices for all interior environments.
