It is really hard to make a Museum environmentally sustainable because museums have such stringent climate control needs. But check out what Huffington Post said about this kids museum in SF:
The Exploratorium is an interactive science museum that also demonstrates innovation and sustainability in its design and construction. The building takes advantage of the historic pier shed’s natural lighting and the 800-foot-long roof provided room for a 1.3 megawatt photovoltaic array. The water of the bay is used for cooling and heating. Materials were used that are both sustainable and durable enough to withstand a harsh maritime climate. The project is certified LEED Platinum and is close to reaching its goal of being the country’s largest Net Zero energy museum and an industry model for what is possible in contemporary museums.
