Net Zero Water - Bullitt Center Case Study

As our current water systems face more and more challenges, we need to learn better ways to manage our water use. Nature is by far the best engineer for us to model. And the Bullitt Center, the greenest commercial office building in the world, is the other. This video describes the Bullitt Center’s net zero water system which is designed to mimic the functions of nature. The building harvests all its water from the rain and once the water is utilized it’s cleaned and returned back to the natural system. A fascinating story of high tech meets old nature.
