Seattle Branch Programs Include:

Quarterly Lecture Series meetings highlight pertinent Green Building issues. The series is designed to offer members and potential members a place to network and learn about green building in the Puget Sound area. Agendas include updates on chapter and national business. Presentations with a strong educational focus are given by area green building professionals representing various industries.

Seattle LEED User Group or “SLUG” meetings give LEED Users the opportunity to learn from each other, and featured speakers, in presentation and open discussion of LEED issues. Meetings are currently the 2nd Tuesday of each month at 901 Fifth Avenue, Fifth Floor room, downtown Seattle. These meetings are free for members, with a suggested donation of $5 for non-members.

Eastside LEED User Group (ELUG) meetings focus on supporting knowledge and education of LEED credits and sustainable design and building processes. ELUG meets the third Tuesday of each month at GLY Construction, 200 - 112th Avenue NE, Suite 300, Bellevue, WA 98004 from 7:30-9:30am.

The North Sound LEED User Group (NoLUG) meets the 3rd Wednesday of each month at noon at the Public Utilities District in Everett to talk about LEED, the green building rating system operated by USGBC.

Building Tours: We identify premier examples of Green Building in the Central Puget Sound area and organize informative tours of these venues that showcase some of the best green practices in the region. 

Emerging Professionals is an outreach program to students and recently graduated young professionals wanting to learn more about green building. Please see the chapter website for more information.
