As the recession grinds on, some consultants are finding an emerging outlet by updating older buildings from power hogs into green stewards. The trend is attracting a fresh round of eco-savvy tenants. Chicago is home to two large projects, examples of advancing efforts to green up existing buildings. In early December, 172 buildings nationwide were certified under the U.S. Green Building Council’s LEED for Existing Buildings Rating System, a program created in 2004. More than 2,000 other buildings are seeking to obtain such certification, according to the Washington, D.C.-based group. Photo: Merchandise Mart Properties Inc. The 79-year-old Mart’s green makeover
The Tennessee Valley Authority has had a second leak at an impoundment at a coal-fired powerplant, this time from a gypsum pond at its Widows Creek Fossil Plant in northeast Alabama. The incident prompted Sen. Barbara Boxer (D-Calif.) to announce on Jan. 13 that she plans to seek federal regulation of coal-ash ponds across the U.S. Shifting gypsum dislodged the cap covering a 30-in. pipe once used to drain water from the gypsum pond into an adjacent settling pond, says John Moulton, a TVA spokesman. Once the cap came off, water in the gypsum pond flowed into the settling pond,
Every fall, during low-water time on the Mississippi River, a crew of about 300 men and women turns out to resume one of the longest-running and most important construction projects of the U.S. Army Corps of Engineers—the placement of articulated concrete mattresses along the levees to prevent scour and protect communities.

A public-private partnership in the San Francisco Bay Area plans to build a $1-billion network of electric-car charging stations, while in Portland, Ore., a utility and two private firms already are erecting electric vehicle battery-charging stations in a cluster of nearby cities.

Ted Kulongoski (D) to supply electric vehicles to the state’s fleet in 2010. Nissan also committed to work with the state, in partnership with utility Portland General
Dropping demand for gasoline has taken a chunk out of last year’s super-high prices, and refiners are shifting capital expenditures accordingly. Prices for gasoline rose 7.1¢ on Jan. 5 to $1.68 per gallon but were still down 46% overall since a year ago, reports the federal Energy Information Administration. On-highway diesel prices fell 3.6¢, to $2.29, a 32% drop since 2008 and the lowest in years. Despite the winter price rollback for both fuels, diesel is “the growth fuel, globally,” says Allen Schaeffer, executive director of Washington, D.C.-based Diesel Technology Forum. As such, ExxonMobil Corp. and others are boosting output
A group of engineers and scientists will host a conference this spring to push for development of design criteria for storm-surge barriers to protect New York City. Global warming, rising sea levels and more frequent and violent storms mean the city inevitably will face a devastating hurricane, says conference organizer Douglas Hill, a consulting engineer and adjunct lecturer at the School of Marine and Atmospheric Sciences at Stony Brook University, Stony Brook, N.Y. Hill is working with the American Society of Civil Engineers N.Y. Metropolitan Section’s Infrastructure Group and the New York Academy of Sciences, as well as with municipal
The U.S. Army Corps of Engineers has released for public comment its proposal for the Gulf Intracoastal Waterway West Closure Complex, a surge protection project that will include a 20,000- to 25,000-cu-ft-per-second capacity pump station, the largest in the nation. The GIWW Closure Complex will likely be the largest component of the Greater New Orleans Hurricane and Storm Damage Risk Reduction System. Located just south of New Orleans on the west bank of the Mississippi River, it is intended to reduce risk from a storm event with an intensity that has a 1% chance of occurring in any given year.
A proposal by a North Carolina artist is laying the foundation for what may become the largest in-situ residential soil-lead remediation project in the country. Artist Mel Chin’s work often brings site-specific art to unlikely places, including destroyed homes and landfills. He has worked with scientists in the past to create gardens of hyperaccumulators—plants that draw heavy metals from soil. Now he is attracting academic, engineering and social resources to ask Congress for $300 million to address soil-lead contamination in New Orleans.

States must now certify that their building codes meet tougher energy-efficiency requirements under a new determination by the U.S. Dept. of Energy. DOE says it has established the latest standard from the American National Standards Institute/American Society of Heating, Refrigerating and Air-Conditioning Engineers, Standard 90.1-2004, as the commercial building reference standard for state building energy codes.
The U.S. Court of Appeals for the D.C. Circuit has reinstated the Bush administration’s Clean Air Interstate Rule (CAIR) until the Environmental Protection Agency develops a new clean-air program for powerplants. The court struck down the rule, which had been touted as the centerpiece of the administration’s air quality program, on July 11, saying it had “fundamental flaws.” But the court decided to revisit the issue after EPA, Environmental Defense Fund and several states asked for the rule to be reinstated. In its Dec. 24 ruling, the court concluded that despite “relative flaws” of CAIR, allowing the rule to remain
