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
数组,万岁!图片由NREL而造成l Renewable Energy Laboratory in Colorado. Thanks to its arrays of photovoltaic cells with a total production capacity of 973 kW, the nation's largest net-zero energy-use building produced as much energy as it used on June 22. National Renewable Energy Laboratory researchers in the Dept. of Energy's 220,000-sq-ft Research Support Facility expect the Golden, Colo., building to achieve NZEU for the month of July, assuming the sun continues to shine. DOE's Jeffrey M. Baker, the facility's visionary and ENR's 2011 Award of Excellence winner, reports the year-old building is performing as designed (ENR
As they sift through debris from one of the deadliest tornadoes in U.S. history, designers, builders and inspectors in Joplin, Mo., are evaluating the condition of the structures that survived the May 22 disaster and learning more about those that did not. Courtesy Thornton Tomasetti KILLING FLOOR An EF5 tornado cut a mile-wide swath through the heart of Joplin, Mo., leaving more than 150 people dead. The Reston, Va.-based American Society of Civil Engineers sent a technical assessment team to Joplin to evaluate the extent of the damage and determine whether modifications to ASCE standards are warranted.ASCE also plans to
More than four years after an EF5 tornado flattened Greensburg, Kan., and killed 11 of its 1,500 residents, business and home owners continue to rebuild in a fashion that embraces sustainable design, if not more stringent building codes.

Further, if the rebuilding received financial assistance from the Federal Emergency Management Agency,
MARTELLY Fifteen months after an earthquake devastated Haiti's capital, the country's newly elected president, Michel Martelly, says he recognizes that he and his nation face a major rebuilding task.马特利(Martelly)在4月20日与华盛顿特区希拉里·克林顿(Hillary Clinton)举行的会议上发表讲话,他通过口译员说:“显然,我面前面临着巨大的挑战,但我打算与他们见面。”他补充说:“重建过程非常缓慢。”前艺人马特利(Martelly
One night in early March as well as the next day before dawn, the Dept. of Energy’s Jeffrey M. Baker wasn’t pleased when he noticed lights still burning on two floors of his pet project: the National Renewable Energy Laboratory’s new, ultra-green office building in Golden, Colo. “The cleaning staff probably left them on,” said Baker, who oversees the lab.

Constructing any major hospital is a challenge, but building a 320-bed state-of-the-art teaching hospital for $16 million in the highlands of Haiti is fraught with difficulties. Yet the aid group Partners in Health (PIH) is doing just that, using funds that come not from the government or the United Nations but from donations collected by the Boston-based group, which has worked for 23 years to boost the capacity of Haiti’s public health sector. The materials, services and cash contributions are coming from private companies and organizations, especially from companies in the U.S. construction sector. The hospital, which will have six
Haselden Construction and architect RNL put almost everything on the line for the Energy Dept.’s Research Support Facility in Golden, Colo. The firm-fixed-price contract, at $64 million, was risky, says Byron Haselden, even after terms were sweetened to include a $2-million incentive award fee and the contract adjusted so the team did not have to commit to a price in its proposal.

数以百计的屋顶在东北倒塌a series of winter storms swept through the region from just before Christmas until the week after Groundhog Day, with minimal thawing in between. The accumulated loads proved more than many commercial flat-roof systems could handle. Photo: Courtesy Town Of Nottingham, N.H. Roof of Nottingham, N.H., town garage proved no match for series of winter storms. Injuries were minimal, but as the tally of structural failures mounted, some began to wonder whether it is time to re-examine building codes if the region is entering a climate-change cycle that will trigger increased precipitation
