The Sustainable Sites Initiative led by the partners developed the rating system out of four years of work by dozens of the country’s leading sustainability experts, scientists and design professionals, as well as public input from hundreds of individuals and dozens of organizations, to create this missing link in green design. The announcement took place at the U.S. Botanic Garden in Washington.
“While carbon-neutral performance remains the holy grail for green buildings, sustainable landscapes move beyond a do-no-harm approach,” said Nancy Somerville, executive vice president and CEO of ASLA. “Landscapes sequester carbon, clean the air and water, increase energy efficiency, restore habitats and ultimately give back through significant economic, social and environmental benefits never fully measured until now.”
“We are facing unprecedented environmental challenges such as water scarcity and climate change that require fundamental changes in the way that we interact with the land," said Susan Rieff, executive director of the Lady Bird Johnson Wildflower Center. “This voluntary rating system and guidelines cover all aspects of working with outdoor spaces of all sizes, and provide information for designing landscapes that go beyond beauty to actually improving ecosystem health and the health of communities for generations to come."
“Landscapes can give back,” said Holly H. Shimizu, executive director of the United States Botanic Garden. “We believe that as these guidelines become widely used, not only will they be as transformative to the landscape industry as LEED was to buildings, but more than that, they will allow built landscapes to be regenerative like natural landscapes, and assist in mitigating some of the most pressing environmental issues we face today. We need to acknowledge our landscapes’ value, treasure them and cultivate them sustainably and responsibly. The need is urgent, the time is now and these guidelines, when used correctly, are the tools.”
The rating system works on a 250-point scale, with levels of achievement for obtaining 40, 50, 60 or 80 percent of available points, recognized with one through four stars, respectively. If prerequisites are met, points are awarded through the 51 credits covering areas such as the use of greenfields, brownfields or greyfields; materials; soils and vegetation; construction and maintenance. These credits can apply to projects ranging from corporate campuses, transportation corridors, public parks and single-family residences. The rating system is part of two new reports issued from the Initiative, “The Case for Sustainable Landscapes and Guidelines” and “Performance Benchmarks 2009,” both available for download at www.sustainablesites.org.
To test the rating system, the Sustainable Sites Initiative opened a call for pilot projects in conjunction with the release of the rating system. Any type of designed landscape is eligible, so long as the project size is at least 2,000 square feet. The call will remain open until Feb. 15, 2010, and the initiative will work with and oversee the projects during the two-year process. More information about the pilot projects is available at www.sustainablesites.org/pilot.

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.
When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...
Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur
What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...
The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.
Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
