美国绿色建筑委员会和绿色成矿ding Certification Institute have released an improved version of the green-building rating system, which standardizes language across all categories and overhauls the LEED-accredited professional system, turning it into a tiered program. The current release includes LEED 2009, LEED Online Version 3 and a new certification process based on ISO standards. It also updates all the LEED categories at once, including those for new construction, schools, core and shell, commercial interiors and existing buildings. LEED Online V3, the implementation tool, has been retooled to be faster, more responsive and stable. USGBC has seen
The U.S. Army Corps of Engineers has started staged award of a $500-million-plus contract for construction of the Gulf Intracoastal Waterway West Closure Complex in southeast Louisiana. It is expected to be the largest and most complex piece of the Greater New Orleans Hurricane and Storm Damage Risk Reduction System. Included are extensive flood-wall systems, a 20,000-cu-ft-per-second pump station and two sector gates of about 225 ft and 75 ft in width, all built next to a federally designated “nationally significant” wetland, says Kevin Wagner, Corps senior project manager.

The U.S. Army Corps of Engineers and the Port Authority of New York and New Jersey have released a draft plan for the restoration of the Hudson-Raritan Estuary that they hope will lead to a more coordinated effort to remediate the heavily polluted area. Released on April 14, the two-volume Comprehensive Restoration Plan (CRP) provides a framework for restoring the estuary. Corps officials say the plan represents a consensus view of how the estuary—roughly defined as the waters and wetlands within a 25-mile radius of the Statue of Liberty—should be restored. Sources say the plan, the result of a 1999
The Interior Dept. is maintaining its aggressive pace in committing economic-stimulus funds for construction and maintenance projects around the country. Interior’s National Park Service on April 22 released a $750-million list of projects to be funded under the stimulus measure, the American Recovery and Reinvestment Act. The roster contains 766 projects, including work on a wide range of buildings, monuments, trails and water and sewer lines. Plan includes $30.5 million for repairs to the Lincoln Memorial reflecting pool. Interior Secretary Ken Salazar followed up the park news on April 25 by rolling out the $500-million stimulus plan for the Bureau
Scheduled water deliveries from the Colorado River will be short 60% to 90% of the time by mid-century if human-caused climate change continues to reduce precipitation in the basin, say state researchers at Scripps Institution of Oceanography at the University of California, San Diego. “The situation is horrible,” says Tim Barnett, Scripps research marine physicist. “We’re using all the water that is there, and there is going to be less of it.” Coincidentally, on May 15, scientists at the National Center for Atmospheric Research (NCAR), Boulder, Colo., will publish a report with similar findings from a study of major rivers

The amount of federal economic-stimulus work continues to grow, with the April 15 announcements that the Interior Dept.’s Bureau of Reclamation has committed $1 billion to projects throughout the West and that the Environmental Protection Agency is dividing $600 million among Superfund projects at 50 sites.

BuRec included about 30 large projects and an unspecified number of smaller ones that it plans to finance through the stimulus, the title of which is the American Recovery and Reinvestment Act (ARRA). California will receive the largest share at $260 million.
Six coastal states will receive nearly $500 million from the U.S. Interior Dept. to help them alleviate environmental impacts of oil-and-gas development, the agency said on April 20. Louisiana tops the list with $121 million, followed by Alaska at $37.5 million, Texas at $35.6 million, Mississippi at $23.8 million, Alabama at $19.7 million and California at $5 million. The agency will distribute the funds in fiscal 2009 and 2010, the final two years of the Coastal Impact Assistance Program, which Congress created in 2005 for states adjacent to oil-and-gas production on the Outer Continental Shelf. Lawmakers authorized the agency to
虽然uncertain exactly how the U.S. will address climate change, it is clear that any regulations aimed at reducing the nation’s carbon footprint will impact construction—for better and for worse. Potential winners are those companies that build powerplants, transmission lines and install energy-efficiency measures. Firms that are leaders in sustainable building and design are also well positioned to profit from carbon regulations. Potential losers, however, will not be as clear until legislation to regulate carbon is finalized. “There are ways that it can have benefits and drawbacks,” says Calli Schmidt, spokesperson for the National Association of Home Builders.
Last week, Webcor Builders and Climate Earth announced a partnership to create the first database of greenhouse-gas emissions from the construction supply chain. The idea is to measure and catalog carbon footprints created when producing building materials, from glass and drywall to steel and concrete. Webcor says the goal is to establish a consistent means for the construction industry to measure the carbon equivalent of its products. Climate Earth will quantify greenhouse gases that are generated, including during mining, manufacturing and transporting. Data from Webcor’s construction projects and Climate Earth’s Enterprise Carbon Accounting system will quantify the emissions in units
