Santa Monica will host the Sixth Annual AltBuild Expo this weekend to display the best of green building practices and design.

AltBuild, which stands for the Alternative Building Materials & Design Expo, will include speakers and noted exhibitors within the green community. The Expo is a much-anticipated event that brings together members of the building community, including architects, designers, contractors, retail buyers, government representatives and the general public to learn more about the new frontier of sustainable building.

The first day, Friday, May 8, is devoted to professionals within the design, architecture and construction communities. They can attend seminars on sustainable landscaping and institutional architecture.

Saturday, May 9, is open to the public. Saturday’s workshops will feature sustainable design, green residential remodeling and issues surrounding new technologies in green building.

“The stars seem aligned for the 2009 AltBuild show,” said Brenden McEneaney, green building program advisor for the City of Santa Monica. “Contractors are looking to differentiate their services in a slow economy, homeowners are looking to tighten their belts by reducing utility bills and developers are looking for ways to increase values in a depressed market.”

Special features include food from the Jackson Café, Livingreen & Book Signings, demonstrations and bike valet. Hands-on mini classes will be going on throughout the event for composting, changing out sprinkler heads and more.

Admission to AltBuild is free. For seminar and speaker schedules, event hours and general information, visit the Web site as www.altbuildexpo.com.
