The Exploratorium

Challenge

The Exploratorium, a world-renowned science museum located on Piers 15 and 17 in San Francisco’s historic Wharf area, aimed to achieve Net Zero energy consumption without sacrificing function and aesthetics. The challenge was to design a facility that could push the limits of green building while accommodating high public usage and meeting stringent egress criteria set forth by the Port Authority and State Historical Society.

Solution

The project involved innovative energy systems such as a bay water cooling system, radiant heating and cooling, and a 1,300 KW PV rooftop system. Extensive use of daylighting was implemented, which is unusual for a museum, and the overall lighting power density was maintained at 0.78 watts per square foot, including all building-mounted exhibit lighting loads. The lighting systems were controlled through fully programmable breakers, occupancy sensors, daylight sensors, and low voltage control stations. Exterior lighting systems included custom pole bases that also served as utilities for power and data, and low glare, full cutoff luminaires addressed light pollution and trespass.

Outcome

The Exploratorium successfully achieved Net Zero energy consumption while maintaining its function and aesthetics. The facility received the 2016 AIA COTE Top Ten Award and LEED Platinum Certification. The innovative lighting design and energy systems have significantly enhanced the user experience, making the museum a beacon of sustainability and education.
