The Sonoran Green Expo 2010 is being held this Saturday, Oct. 23, at M3 Architects, 2051 W. Sunset at River and La Cholla in the Northwest.
A number of vendors are displaying their green ideas and products, and the show is free and open to the public. During the day, there are public sustainability workshops, as well as a keynote presentation by Jerry Yudelson, author of "Dry Run: Preventing the Next Urban Water Crisis." Yudelson speaks at noon Saturday.
A sustainable home tour, hosted by the U.S. Green Building Council's Southern Arizona branch, runs from 1 to 5 p.m. The tour, priced at $20 per person, has stops at no fewer than three green-built homes.
The U.S. Green Building Council's Arizona chapter was one of the first state chapters in America when it was certified in 2002. A separate Southern Arizona branch was formed in 2007. It advocates for "sustainability in the built and social environment," and seeks involvement of businesses, organizations and institutions, a release said.
