Evergreen Sustainable Development Standard


About Evergreen 

The Evergreen Sustainable Development Standard (ESDS), now in Version 3.0, is a green building performance standard required of all affordable housing projects receiving capital funds from the Washington State Housing Trust Fund.

Green building improves the economics of managing affordable housing, promotes environmental quality, and enhances quality of life for residents. 

The Evergreen Sustainable Development Standard (ESDS) was developed in compliance with the law and contains criteria that safeguard health and safety, increase durability, promote sustainable living, preserve the environment, and increase energy and water efficiency. In addition to complying with all mandatory provisions, new construction projects must achieve 50 points from the optional criteria, while rehabilitation projects must achieve 40 points from the optional criteria.

As the body of sustainable building practices improves over time, it necessitates updates to ESDS. To determine which Version of ESDS your project must comply with, please review the table below.
