The LEED Gold Student Union at Los Angeles City College is a multi-story landmark celebrating diversity and community; a flagship facility that is sustainable, timeless and celebratory of the campus Hollywood history and legacy. The program supports these goals by including an extensive range of services, organizations and multi-use interior and exterior spaces for student and community activities and interaction. The building is highly energy efficient— using its concrete structure as thermal mass which combined with night flushing minimizes the use of the HVAC system. It takes great advantage of functional daylighting by employing large north facing glass walls, shaded south windows, and extensive skylights.
