At the GreenBuild 2015 conference in Washington, D.C., Jamie Statter, vice president of strategic partnerships for the U.S. Green Building Council (USGBC) and the Green Business Certification Inc (GBCI), its credentialing arm, announced that Sustainable Sites Initiative (SITES) certification is now available for landscape projects worldwide. Also, some form of SITES credential, a “SITES AP,” will become available at some point in the future. Speaking to landscape architects and designers, she said “you will be able to differentiate yourself as a SITES professional in the marketplace.”
SITES was developed over 10 years by the American Society of Landscape Architects (ASLA), the Lady Bird Wildflower Center at the University of Texas at Austin, and U.S. Botanic Garden. In the past few years, hundreds of projects sought certification under the SITES pilot program; 46 projects achieved some level of certification. In 2015, GBCI announced that it would acquire SITES and now certify projects under SITES v2. Already more than 15 projects, including two iconic international projects, have registered for certification under SITES, and many more are expected in coming months.
Statter said that “parks and green spaces are now more important than ever,” and they can only be improved through the use of SITES in their design, construction, and operations. She also thinks that SITES will be beneficial with mixed-use developments with a landscape component and parking lots.
SITES has a number of key goals: it will “help create regenerative systems and foster resiliency; mitigate climate change and increase future resource supply; transform the marketplace for landscape-related products and services; and improve human health and well-being.” Jose Alminana, FASLA, a principal at Andropogon Associates and a leader in the development of the SITES rating system, concurred, saying that SITES is a useful tool for helping clients and designers “stitch together systems to improve a landscape’s ability to absorb change.”
SITES is based on a different logic than LEED, GBCI’s rating system for buildings: its approach is based in living systems. He said once a building, which is a static system, has been created it begins to deteriorate. But once a landscape, an ever-evolving living system, has been installed, it only begins to take off. “Landscapes can be regenerative.”
Given landscape architects and designers must not only design for people but also all sorts of other wildlife, a system-based approach is critical. “There are forms of life that have co-developed together. With landscapes, it’s not a set of individual elements. You can’t have plants without soils.”
SITES can also have broader impacts on the design process and marketplace. Statter said “projects will now need integrated design teams from the get-go. SITES is a tool for involving landscape architects and designers much earlier on in the design process.”
Alminana added that SITES will only increase the “transactional power” of landscape architects and designers. With SITES, they will now know the “carbon impact of all the materials they source. They can then demand that things are done in a low-carbon way.”
And once the U.S. and other countries move to a regulatory environment that taxes carbon, “landscapes will become invaluable.” When carbon becomes money, “it will be critical to actually monitor the systems in our landscapes.”
U.S. and international landscape architects and designers are encouraged to seek certification for their projects. SITES v2 uses LEED’s four-level certification system: certified, silver, gold, platinum. The rating system is free and the reference guide is available for a fee. Alminana said the “reference guide took over 10 years to develop. Everyone should get one and have fun with it.”
