Interior Space and Exhibition Design Green Light Forest Ecology Exhibition by HUANG YU-JUNG Green Light Forest is an ecology exhibition designed for a forest park visitor center at 2000 meters elevation in Wulong, Chongqing, China. The interior covers about 900 square meters on two floors, inside a triangular building shaped after the mountains. A zigzag ribbon form, drawn from a local legend, flows through the space in four colors. Each color marks one theme: forest formation, habitat, geology and environmental protection. Exhibition elements hang from the ceiling to keep the floor open. Laser projection, LED screens and sensors allow the content to change.
