Project Overview: (www.sustainable

The Center for Sustainable Landscapes (CSL) at Phipps Conservatory and Botanical Gardens

was designed to be the first project in the world to simultaneously achieve LEED Platinum,

SITES four-star certification, and The Living Building Challenge. Built on a previously paved-

over city maintenance yard and documented brownfield, the nearly 3-acre site supports a new

24,350-square foot education, research, and administrative building; manages all sanitary waste

and a 10-year storm event on site using a range of green infrastructure strategies; has

successfully reintroduced 150 native plant species; and is designed to be net-zero energy and

water. The CSL is open to the public and its building and landscape performance is being

extensively researched and monitored to inform the design and construction of similar projects

that restore ecosystem services, generate their own energy, and clean and re-use their own

waste water.
