Abstract:
The new David Brower Center in Berkeley, CA, named after one of the preeminent environmentalists of the twentieth century, incorporates many features of sustainable design in the structural, mechanical, electrical, plumbing, and lighting systems and is expected to be certified LEED® Platinum. In this highly seismic region, a major aspect of sustainable construction is continued functionality of the structure after the occurrence of a large earthquake. To protect the building, the structure integrates a unique combination of post-tensioned concrete walls and frames that improve performance, limit damage, and make efficient use of construction materials. This system protects the investment in energy and materials and is a key component of the project’s "green" construction goals. Specialized concrete mixtures, with large volumes of portland cement replaced with slag cement, were also integrated into the design to reduce the embodied energy and carbon footprint of the structure.
