Landscape Rating System Publicly Available

Today, Green Business Certification Inc. (GBCI) announced its acquisition of the SITES rating system, the most comprehensive program and toolkit for developing sustainable landscapes.

SITES was developed through a collaborative, interdisciplinary effort of the Lady Bird Johnson Wildflower Center at The University of Texas at Austin, the American Society of Landscape Architects (ASLA), and the United States Botanic Garden.

The rating system can be applied to development projects located on any landscape with or without a building. The Wildflower Center and ASLA will help GBCI create and implement SITES credentialing and certification offerings, and will provide training for projects interested in applying SITES at corporate campuses, streetscapes, homes, and other  landscapes. 

“Landscapes knit together the fabric of our communities,” said Rick Fedrizzi, CEO, GBCI. “And sustainable landscapes are critical in their ability to reduce water demand, filter and reduce storm water runoff, provide wildlife habitat, reduce energy consumption, improve air quality, improve human health, and increase outdoor recreation opportunities. SITES is an important addition to our toolkit, and GBCI appreciates this opportunity to support this additional contribution to healthy, thriving communities and neighborhoods.”

GBCI is a non-profit organization that provides third party certification and credentialing services for the widely used LEED (Leadership in Energy and Environmental Design) standard and several other standards. 

“It is exciting to see years of work developing and field testing SITES culminate with the availability of this rating system,” said Fritz Steiner, FASLA, dean of the School of Architecture at The University of Texas at Austin. “The depth and breadth of approaches that were implemented by pilot projects demonstrates how valuable SITES can become for revolutionizing our relationships with built landscapes.”

“Landscape architects and members of all the related design and planning fields know that the issues addressed in SITES are increasingly important to creating livable and resilient communities,” said Nancy C. Somerville, executive vice president and CEO of the American Society of Landscape Architects (ASLA). “GBCI will take SITES to the next level and ensure its future growth and influence, and ASLA is pleased to provide continued education and communications support.”

“SITES is a powerful tool for enhancing built landscapes precisely because it puts ecosystem services, the benefits humans derive from functional ecosystems, front and center,” said Ari Novy, executive director of the United States Botanic Garden. “This approach will help maximize our collective ability to create sustainable and healthy communities. Making SITES available through GBCI will be a great boon for the quality and resilience of our built landscapes.”

The SITES rating system uses progressive industry standards for landscape design and incorporates additional recommendations from technical experts in the fields of soil science, botany and horticulture, hydrology, materials, and human health and well-being. Some of the credits for sustainable landscape performance have been developed in alignment with similar credits in the U.S. Green Building Council’s LEED rating system, the world’s most widely used green building program. 

SITES, originally modeled after LEED, includes best practices in landscape architecture, ecological restoration and related fields, and knowledge gained through peer-reviewed literature, case-study precedents and projects registered in the SITES pilot program.

“Adding SITES to GBCI’s rapidly growing list of certification systems and credentials it supports not only expands GBCI’s capabilities, but it also helps us to further our mission to enact global sustainable change,” said Mahesh Ramanujam, President, GBCI.

SITES was under development for seven years at the Wildflower Center under the guidance of the original program collaborators. It draws on the experience gained from a two-year pilot program involving more than 100 projects. Forty-six of these pilot projects have achieved certification, including landscape projects at corporate headquarters, national and city parks, academic campuses and private homes.

Interested project teams can visit www.sustainablesites.org for more information and to register their projects and access the SITES v2: Rating System For Sustainable Land Design and Development, a guide that provides best practices, performance benchmarks and tools for creating ecologically resilient landscapes, and rewards successful projects through certification.
