ABSTRACT
The Phipps Conservatory and Botanical Gardens’ 24,000-gross-square-foot building was constructed for $11.8 million in 2012. Located on a 2.7-acre site on a 15-acre campus, the Center for Sustainable Landscapes (CSL) provides office, classroom, and library space for the Phipps. Part of the organization’s mission is “to advance sustainability and promote human and environmental well-being through action and research,” and this building was seen as a tool for implementing that mission. Multiple building and site assessment systems were implemented in this project. The CSL was certified as LEED Platinum in 2013, net zero energy in 2014, and as a Living Building in 2015. It is also certified through the SITES and WELL pilot programs. (See Box 8.1 for a project overview.) Box 8.1: Project overview https://www.niso.org/standards/z39-96/ns/oasis-exchange/table">
