De Anza College Media and Learning Center

This 52,000-square-foot, state-of-the-art academic building is located on the main campus of De Anza College. The project features teaching labs and classrooms, distance learning facilities, a television studio, and two 100-seat lecture halls. WSP provided MEP engineering and high-performance design by built ecology on the project, which earned LEED Platinum certification.

Achieving LEED Platinum

To achieve the high levels of sustainability necessary for a LEED Platinum certification, the WSP USA team implemented a number of innovative features. Natural lighting is used to significantly reduce the energy from artificial lighting in the classrooms and atrium. The design incorporates an innovative buoyancy ventilation system to provide heating, cooling and ventilation in classrooms and offices. 100% outside air is supplied via downdraft shafts into a raised floor and hot air is passively displaced upwards and out through a central atrium.

The design takes advantage of Cupertino’s relatively mild climate, with external temperatures frequently around the air supply temperature of 65F. Solar thermal evacuated tube collectors are used to provide 40% of the heating hot water demand. The optimized building orientation and external shading control heat gain to reduce cooling energy.
