A report from a non-profit think tank highlights some of the barriers several cities and states have experienced in implementing new building-energy benchmarking and disclosure policies, as well as some suggestions for ways to overcome those barriers.Within the past five years, five cities and two states have adopted policies that require owners of large, commercial buildings to measure their properties' energy consumption and make the data publicly available. The jurisdictions are in New York City, Washington, D.C., Seattle, Austin, Texas, San Francisco and the states of California and Washington.Although the policies are on the books, some of the jurisdictions have

The expressed steel framing for the grand-scale sculptural transit hall of the WTC’s Transportation Hub, designed by architect-engineer Santiago Calatrava to evoke a dove of peace, already has been simplified to keep it from literally flapping its wings. Yet it still is going to be “as challenging a steel project as it gets,” says Dan Payea, vice president of operations for Skanska Koch, a Carteret, N.J.-based division of Skanska Civil

This week, ENR writes the next chapter in its historic coverage of the 16-acre World Trade Center site in Lower Manhattan. More than 100 articles have been filed over the years. The first was in 1958, when “New Face for Lower Manhattan” described the $1-billion plan—delivered to Mayor Robert F. Wagner—that would bring sharp changes to the financial district.We trace the “World Trade Center Over Time” through the pages of ENR since that first story.In the 1960s, ENR wrote about the controversies surrounding the proposed development, including stories about the team, the design, the wind-tunnel tests, construction of the slurry-wall

The hundreds of people cooperating and coping at Ground Zero, many of whom are otherwise fierce competitors, have many reasons for putting up with the added hassles, restrictions and sacrifices.

Fifteen years in the making, the memorial faced challenges—ranging from an extensive approval process to a site on the National Mall made of fill from the Potomac River—before construction could start in late 2009. Two years later, the design-build team, the first use of the delivery system for a memorial on the Mall, will deliver the $120-million vision within walking distance of the spot where Dr. King delivered his

In draft recommendations released on August 11, the Shale Gas Subcommittee of the Secretary of Energy Advisory Board called for industry leadership in improving environmental performance, underpinned by strong regulations and rigorous enforcement of those regulations.The subcommittee was
