HLS North Hall achieves LEED Gold certification

first_imgOriginally built in 1960 as a hotel, Harvard Law School’s (HLS) North Hall has recently earned LEED Gold certification through the LEED for Commercial Interiors (LEED-CI) version 3.0 rating system for its conversion into a 112 room dormitory for students at Harvard Law School. North Hall is Harvard University’s 44th LEED certification and the third project to achieve LEED certification at HLS.The efficiency strategies implemented during this renovation highlight both HLS’ and Harvard’s commitment to greenhouse gas reduction and achieving the University-wide goal of reducing emissions 30% below 2006 levels by 2016, inclusive of growth. This project is particuarly impressive because despite being a life safety project, the project team recognized the opportunity to streamline processes by implementing energy conservation measures and capitalizing on other sustainability measures while the project was being designed and constructed.An energy recovery system that pre-treats fresh air with conditioned exhaust is expected to save HLS approximately $50,000 and reduce emissions by 159 MTCDE annually. Common areas in the building such as the entry lobby, laundry room, and kitchens feature high efficiency LED lighting. Early analysis of the existing lighting determined that in many instances too much artificial lighting was being provided. For certain fixtures the design team was able to cut lighting demand in half simply by replacing two-lamp fixtures with one-lamp replacements. These lighting improvements in aggregate are expected to reduce the electrical demand by more than 40% when compared to the already rigorous ASHRAE 90.1-2007 standard.More than 96% of the interior elements such as ceilings, flooring, and wall partitions were able to be retained, and over 11 tons of furnishings and electronics were salvaged for use in other projects on campus. An impressive construction waste recycling rate of 95% was achieved.For more information on the project and its sustainability features, check out the North Hall Renovations case study on the Green Building Resource website.last_img read more

Some H2N2 virus samples lost in transit

first_img A team was en route a warehouse in Mexico yesterday to find and destroy a sample that had just been located, Stohr said. April 19, 2005 (CIDRAP News) – What began as a routine attempt to measure laboratories’ testing proficiency has become a mission to track missing shipments of potentially lethal influenza viruses in Mexico, South Korea, and Lebanon. In South Korea, investigators were puzzling over conflicting accounts. Officials at three labs said they had never received shipments made last year, but the shipper had signatures showing they had been delivered, Stohr said. Canadian researchers discovered in March that the virus they had been sent was the same that emerged in 1957, prompting the call for the samples to be destroyed immediately. All three countries have made progress in tracing the missing shipments, and total destruction of the samples remains possible, Klaus Stohr, the influenza program chief for the World Health Organization (WHO), told the Associated Press (AP) from Geneva yesterday. In Lebanon, the shipper of a missing sample had released the virus to another shipper for local delivery, but it never arrived at the lab, Stohr told the AP. People were trying to locate the test kit and destroy the sample. The virus in question, influenza A(H2N2), was responsible for the flu pandemic of 1957-58, which killed an estimated 1 million to 4 million people. Samples of the pandemic virus had inadvertently been sent to 3,747 labs in 18 countries for a routine assessment that usually relies on more benign flu strains. All but about 75 labs that received the samples are in the United States, according to earlier reports. Fourteen labs are in Canada and 61 are in other countries. Most laboratories quickly complied with the WHO request on April 12 to destroy the samples. Labs in the United States had destroyed 98% of their samples as of yesterday, the AP reported. The College of American Pathologists paid a private company, Meridian Bioscience Inc. of Cincinnati, to prepare and send the samples. Why Meridian used the H2N2 virus has not yet been fully explained. Labs use such test kits to check their ability to identify viruses.last_img read more
