This building on the campus of Mills College in Oakland, California includes intensive laboratory facilities, offices and classrooms. Designed by EHDD Architecture, architects and Rumsey Engineers, mechanical engineers, it has achieved a LEED Platinum rating. It is 90 percent more energy efficient than a typical lab in the Bay Area, and 45 percent more energy efficient than required by California's Title 24.
The building's innovative HVAC system provides 100% outside air (no recirculated air) for the whole building, including offices and classrooms, eliminates wasteful reheat in the office spaces and features variable flow exhaust. The laboratories are cooled with indirect and direct evaporative cooling systems, which cost less than a conventional laboratory HVAC system. Offices and classrooms use a combination of natural ventilation and a radiant floor system for heating and cooling.
The building's plumbing design uses low water strategies including ultra low flush toilets, waterless urinals, and sensor-controlled faucets. A unique rainwater collection system incorporates an exterior sculpture, which is exposed and visible to students for teaching purposes. Rainwater collected through the system is used to flush toilets.
