Portland, Oregon - The Center for Health and Healing at Oregon Health and Science University in Portland, Oregon, is the first medical center to achieve a Platinum rating in the U.S. Green Building Council’s LEED Rating System. The 16-story, 400,000-ft2 (37,000-m2) building features a chilled beam and displacement ventilation system, a membrane bioreactor for treating sewage, rainwater harvesting, and a 6,000-ft2 (560-m2), glass-skinned Trombe wall for storing thermal energy.

Making Carpet Environmentally Friendly
September 14, 2007 03:31 PM - Tristan Roberts, BuildingGreen

Few building products are as ubiquitous as carpets and rugs, which cover 70% of U.S. floors, according to the Carpet and Rug Institute, the industry’s trade association. That ubiquity has come with some notoriety, as carpet has been on the front lines of several environmental skirmishes. Emissions of volatile organic compounds (VOCs) and other potentially toxic components from carpets have been widely recognized as an indoor air quality problem. The estimated five billion pounds (2 billion kg) of carpet that is discarded every year in the U.S. has been targeted by government agencies and environmental groups as an unacceptably big chunk of the solid waste stream.

Curbing Key Chemicals Could Beat Kyoto Climate Goals

OSLO (Reuters) - Curbs on chemicals that damage the ozone layer could have a side-effect of reducing far more greenhouse gases than the main U.N. plan for confronting climate change, the U.N. Environment Programme (UNEP) said on Thursday. About 191 governments will meet in Montreal from September 17 to 21 to seek ways to speed up freezing on production and phasing out ozone-depleting HCFC gases, widely used in fridges and air conditioners, that also trap heat in the atmosphere. "If governments accept accelerated action on HCFCs, we can look forward to not only a faster recovery of the ozone layer, but a further important contribution to the climate change challenge," Achim Steiner, head of UNEP, said in a statement.

WASHINGTON - A new report details plans to move the U.S. House of Representatives to carbon-neutral operation by the end of 2008, to reduce energy consumption in House facilities by 50% from 2006 levels by 2017, and to “make House operations a model of sustainability.” The initiative, headed by Speaker Nancy Pelosi (D—CA) and Majority Leader Steny Hoyer (D—MD), calls for the House to achieve carbon neutrality by purchasing electricity from renewable sources, purchasing carbon offsets on the Chicago Climate Exchange, and switching the fuel for the Capitol power plant from coal to natural gas.

Light-Emitting Diodes: Chasing White Light

Light-emitting diodes (LEDs) use semi-conducting materials to turn electricity into light; electrons jump from one material to another, emitting photons as they travel. Different semiconductor materials create different colors of light: most white LEDs use indium gallium nitride (InGaN), which actually emits blue light. The blue light excites a phosphor coating on the lens of the diode, creating a yellow light that mixes with the blue and makes it look white to the human eye. Manufacturers also use closely placed red, green, and blue LEDs to deliver white light.

Torrington, Wyoming - Heartland BioComposites, of Torrington, Wyoming, has commercialized a new breed of composite wood using annually renewable wheat straw rather than wood flour, and has introduced its first product, a privacy fence. The company purchases regional wheat straw and compounds it with post-consumer high-density polyethylene (HDPE). The raw materials, which include 50—60% straw, 35—45% plastic, and less than 5% proprietary additives (described by the company as “non-hazardous and organic”), are mixed, heated, extruded, and cut to length.
