Like Iconic Screen Roles and the Hollywood Sign, Our Buildings Have Withstood the Test of Time. When we think of icons, we conjure up images of people, places and things that withstand the test of time, symbolizing our beliefs, culture and community. Greenbuild 2016 celebrates the icons of our movement. Those who are working in the trenches today, and those who are in line to take up the banner and lead the way into the future. Plan now to join us for an epic celebration at Greenbuild 2016: Iconic Green in Los Angeles, California.
