The California Academy of Sciences is a natural history museum and tourist destination that houses more than 46 million specimens of diverse species, including plants, animals, fossils, minerals, anthropological objects, microscopic samples, and many other collections used for research and education. The museum building was constructed in 2008 by the renowned Italian architect Renzo Piano, using concrete, steel, glass, and thermal insulators—many of which were sourced from recycled materials of the former building. Environmental sensitivity and minimizing damage to natural habitats, along with the use of natural light, pleasant airflow, solar panels, a green roof, and rainwater collection are among the defining features of this landmark. The new Academy was built on the site of the previous structure, adjacent to Golden Gate Park in California, since the old Academy had suffered severe damage during the Loma Prieta earthquake in San Francisco.

On October 17, 1989, a 7.1 magnitude earthquake struck Northern California. In total, more than 18,000 housing units and several thousand other structures were significantly damaged. Nearly one thousand of these buildings were completely destroyed by the earthquake itself, and an additional 500 were demolished afterward. The California Academy of Sciences is one of the oldest natural history museums in the United States and the oldest scientific institution founded west of the Mississippi River. Established in 1853, it has played a vital role in scientific discovery and research, valued both by the public and by the academic community. After 136 years, and following the devastation caused by the earthquake, the Academy initially planned to restore and rehabilitate damaged sections, including the aquarium. However, broad community support and generous philanthropic contributions encouraged the institution to reconsider its vision, ultimately leading to a complete redesign and reconstruction of the complex.

The Academy’s leadership recognized that this redevelopment project offered a unique opportunity to fulfill its mission of advancing environmental sustainability. Designing an eco-friendly building integrated with diverse exhibitions became a way to respond to contemporary environmental concerns while inviting visitors to understand, appreciate, and protect nature. Renzo Piano, the distinguished Italian architect, was chosen to design the new building—an architecture that would embody both sustainability and innovation. The central feature of Piano’s design was a living roof, whose rolling hills echoed the natural landscape surrounding the museum. Additionally, two three-story domes, each measuring 27.5 meters in diameter, were designed to house the Rainforest Exhibit and the Planetarium. Although this ambitious architectural approach significantly increased construction costs, its bold and sustainable design attracted additional investors and ultimately expanded the scope of the project.
