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.

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
