Interested parties have until Jan. 14 to take advantage of the first of two public comment periods on the draft update of the popular Leadership in Energy and Environmental Design (LEED) green-building rating system. The U.S. Green Building Council hopes to release the revised system in November 2012, after an August 2012 ballot. The proposed system builds on LEED 2009, which includes the alignment and weighting of credits for certification, says USGBC. The upcoming version also develops the LEED 2009 framework that allows credits to be applied to specific building types. The draft increases emphasis on integrated process and building
The nation’s biggest landlord, the U.S. General Services Administration, is requiring LEED Gold certification as a minimum in all new federal building construction and substantial renovation projects. GSA is updating its facilities standards by the end of the year to enable the projects to meet the LEED Gold requirement—the second-to-the-highest of four certification levels of the Leadership in Energy and Environmental Design green-building rating system. For projects currently under design that were funded before fiscal 2010, GSA is requiring LEED Gold where possible, after evaluating budget and schedule constraints. For leased properties, GSA is keeping its current requirement for LEED

Related Links: International Living Building Institute Construction is scheduled to begin in about a year and be finished 18 months later on a planned 70 to 100-ft-tall net-zero-energy use building in Portland that would, if completed, rank as the tallest net-zero-energy-use building in the U.S. The team for the $40-million Oregon Sustainability Center, which includes SERA Architects, GBD Architects and general contractor Skanska USA, is beginning a 12-week feasibility phase. Design should start in February. The seven-to-nine-story structure would be the tallest ever proposed
By starting work in late November on a $200-million upgrade of its central transmission system, Vancouver is making its first significant investment in the city’s power grid in 30 years. The project includes construction of an oversized three-story substation to meet future capacity needs and a tunnel beneath one of the city’s major waterways.

Marcel Reghelini, BC Hydro senior project manager, says the work is happening in Mount Pleasant, a fast-growing neighborhood no longer adequately served by three aging substations. “We’re putting in a
As the Federal Railroad Administration pursues regulations regarding inspection of concrete railroad ties, the Massachusetts Bay Transportation Authority last month launched a $91-million project to replace 147,000 concrete ties that began failing in just 10 years. Photo: Courtesy VHB Thousands of precast concrete ties began to fail in just 10 years. In 1997, the MBTA chose concrete over timber ties because Rocla Concrete Tie Inc., a Denver-based precast-concrete manufacturer, claimed they had a 50-year life span compared to 30 years for timber ties. But in 2007, several thousand ties began cracking and crumbling, disrupting train service on the 61-mile Old
David Jones grew up watching the massive Browns Ferry nuclear units being built near his home in Athens, Ala. The son of a pipefitter who worked at the plants, Jones knew as a youngster that he wanted to build nuclear plants for the Tennessee Valley Authority. Thirty years after earning a degree in civil engineering, Jones is heading a team that is building the first nuclear plant in the United States in more than 20 years. “It’s a dream come true for me,” says Jones, vice president of Southern Co.’s two new nuclear units at Plant Vogtle, which is located
While the demand for new large nuclear reactors may have fallen in the United States in response to the recession, interest in smaller, cheaper, scalable nuclear reactors is on the rise.

Southern California Edison plans to install 250 megawatts of solar-power generating capacity in California’s southern and central valleys over the next four years. Another 250 MW could be secured through contracts with independent providers as part of the utility’s $875-million initiative.

The first 50 MW is expected to be online by the end of this year. By the end of this year, SCE expects to have the first 50 MW of capacity online or in the final stage
Developers of two new nuclear reactors in Bay City, Texas, have replaced Irving, Texas-based Fluor Corp. with Baton Rouge, La.-based The Shaw Group as partners in an engineering procurement and construction consortium with Toshiba America Nuclear Energy Corp. Nuclear Innovation North America LLC, a company created by Princeton, N.J.-based NRG Energy Inc. and Toshiba Corp., made the announcement on Nov. 29. Nuclear Innovation plans to expand the South Texas Project nuclear facility with two Advanced Boiling Water Reactors that can supply 2,700 MW of power; it is the first site to use that reactor design. The project is expected to
Administration officials have put the brakes on future oil and gas leasing development in certain areas of the Outer Continental Shelf through 2017, modifying a Dept. of Interior proposal for the OCS leasing program released in March. Interior Secretary Ken Salazar said on Dec. 1 that the updated strategy calls for agency officials to focus their efforts on planning areas that already have leases for potential future development. Consequently, the area in the Eastern Gulf of Mexico that remains under a congressional moratorium, as well as the Mid and South Atlantic planning areas, are no longer under consideration for further
