The U.S. General Services Administration (GSA) has adopted the SITES rating system for its capital construction program.
Green Business Certification Inc.’s SITES is a program for sustainable land development and management and is used by landscape architects, engineers, architects, developers, and policymakers to align land development with innovative sustainable design. SITES certification is for development projects located on sites with or without buildings including national parks, corporate campuses, streetscapes, homes, and more.
GSA is one of the largest and most diversified public real estate organizations in the world with a portfolio of 376.9 million rentable square feet in 8,721 active assets, and more than 144,000 acres of land, including ports of entry and historical properties. The GSA determined that incorporating SITES into the program offers a highly effective and efficient way to ensure environmental performance to meet federal goals on various capital project types.
The rating system provides a metrics-based approach to important concepts like ecosystem services and green infrastructure. The GSA’s decision is incorporated in the 2016 version of Facilities Standards for the Public Buildings Service (P-100), which establishes design standards and criteria for new buildings, infrastructural projects, major and minor alternations, and work in historic structures for the Public Buildings Service (PBS) of the GSA. This document contains both policy and technical criteria used in the programming, design, and documentation of GSA buildings and facilities.
