Though green-building experts and construction lawyers laud the good intentions of the U.S. Green Building Council about its popular Leadership in Energy and Environmental Design green-building rating system, many have serious concerns about at least one new requirement in the latest version of LEED, which went into effect on July 1. The requirement, a “precondition” of certification for all buildings under LEED Version 3, says owners must commit to sharing building energy and water-usage data for at least five years after a new building is occupied or an existing building is certified. Another change sending shudders down the spine of

While the owner of the 2.6-million-sq-ft Empire State Building gears up for a $500-million renovation, designed to cut energy costs by 38% and be a model for other green office-building retrofits, a construction firm that recently moved into its green ESB offices is releasing hard data on the 24,000-sq-ft retrofit. Skanska USA Building, which moved into its 32nd-floor space in November, reports it has reduced its energy bill by 46% over its smaller, previous offices elsewhere.

Architect Ellerbe Becket, Kansas City, has been retained by Nets owner and Atlantic Yards developer Bruce Ratner, of Forest City Ratner Cos., to come up with a new design for the long-delayed and controversial Atlantic Yards basketball and entertainment arena in Brooklyn, N.Y. Ellerbe Becket replaces Gehry Partners. Other key designers, New York City-based structural engineer Thornton-Tomasetti, and mechanical-electrical-plumbing engineer, WSP Flack + Kurtz, will remain on the project. Forest City Ratner says it hopes to unveil new images of the arena, named Barclays Center, in late June and that it intends to break ground later this year in anticipation
High-wire acts and heavy props, used to build the gravity-defying steel “bird cage” on concrete stilts that frames the tallest little theater in Texas, stole the show from myriad balancing acts that combined into a command performance at the Dallas Center for the Performing Arts.
The Appellate Division of the New York state court ruled four to zero to uphold the state’s right to use eminent domain to build the Atlantic Yards megadevelopment in Brooklyn, N.Y. Developer Forest City Ratner Cos. (FCRC), New York City, says it plans to break this year, with the intent that the Nets will play basketball in the planned arena, named Barclays Center, in the 2011-12 season. In 2006, the developer was aiming to move have the Nets into the arena by the 2009-2010 NBA season. According to FCRC, this is the 23rd consecutive ruling in favor of the megadevelopment,
Architects are calling the third version of the popular green-building rating system, Leadership in Energy and Environmental Design, a significant improvement over earlier releases. LEED 2009, which covers new construction, schools, core and shell, commercial interiors and existing buildings, “is a step forward,” says Greg Mella, a principal of SmithGroup, Washington, D.C., and a member of the American Institute of Architects committee on the environment. Under LEED 2009, rolled out late last month by the U.S. Green Building Council, credits are standardized on a 100-point scale. Credits also have been reweighted. Mella deems that important because it recognizes the connection
Some American Institute of Architects’ 2008 model contract documents for integrated project delivery are being challenged by at least one prominent lawyer who also is an architect and general counsel for a major A/E firm. The documents create a limited-liability company called a single-purpose entity (SPE). Do not use these model documents without “competent legal counsel review,” because they are “flawed,” says Bill Quatman, managing director for Burns & McDonnell Engineering Co., Kansas City. The single-purpose-entity agreement sets up a limited-liability company that contracts for design and construction. Under the SPE model, the owner has three managers, controlling the board.
On April 30 at its national convention in San Francisco, the American Institute of Architects released replacement construction manager documents and an updated version of AIA Contracts Documents software. The CM documents cover CM as advisor and CM as constructor. The CM documents replace those released in 2007 and 2008. They include dispute resolution check box that enables parties to select the method of binding dispute resolution. They incorporate the concept of an initial decision maker fill point where the owner and contractor may identify a third neutral party IDM other than the architect. The documents include digital data provisions
On April 27, the U.S. Green Building Council and the Green Building Certification Institute released LEED Version 3. The latest version of the green building rating system, in the works for more than three years, "sets the stage for the growth and improvement of the whole LEED program for the next several years," says Mike Optiz, USGBC's vice president for LEED implementation. The current release includes LEED 2009, LEED Online Version 3 and a new certification process based on ISO standards, administered by the GBCI. It also updates all the LEED categories at once. These include LEED for new construction,
