The second in our series of green infrastructure tours. This time Sonja O'Claire joined the ASCE SF Chapter's Sustainability Committee on a tour of the California Academy of Sciences ("The Academy"). Known as the "greenest musuem in the world," The Academy is an exhibit in-and-of itself for all things related to sustainable design. Tour attendees went behind-the-scenes to learn about the unique design elements The Academy employs to lower its impact on its environment.
