The International Association of Lighting Designers' (IALD) participation at Greenbuild 2006, the largest green building conference in the United States, was a positive return on investment based on the response given by visitors to the association's tabletop exhibit. Greenbuild, the annual conference of the U.S. Green Building Council (USGBC), marks the second exposition, in recent history, at which the IALD has exhibited outside of the traditional lighting industry venues.
