Whether it’s regulatory pressure or voluntary incentives, there are many external forces that affect green building practices. Here we collect info on everything from local codes to award programs to the internal policies of the federal government.
Conserving water goes beyond building design and technology. Water use is governed by federal, state, and local policies, from maximum flow requirements to pricing structures that encourage or discourage conservation.
Nanotechnology takes advantage of the novel properties that particles can exhibit at a billionth of a meter in size. Those properties are being used in building materials, where they can improve thermal performance and the effectiveness of photovoltaics, among many possibilities. The field has little regulation, however, despite significant health and environmental concerns.
With several announcements at the 2006 Greenbuild conference in Denver, the U.S. Green Building Council signaled that it would use its LEED Rating System to reduce greenhouse gas emissions, by tightening LEED requirements and by increasing the number of buildings designed to LEED standards.
Searching for reliable, energy-efficient exit signs, EBN's Alex Wilson explains why photoluminescent exit signs, one of the newest "energy-saving" devices, are one of the worst from a total-energy-use standpoint. The article reviews current technology, including LED and electroluminescent exit signs, and offers recommendations.
Many businesses and homeowners are choosing to buy green power, including renewable energy credits (RECs). This article examines the environmental benefits of green power, including on-site renewables, what REC buyers should know about their purchases, and investing in energy conservation.
Analytical chemistry tools, used together with product testing chambers, are making it possible to "see" product emissions in new ways. Editor Nadav Malin discusses the science behind product emissions testing, the different product certification standards, and what's ahead for this growing field.
Following the recent phaseout of CCA, the dominant wood preservative of the last 30 years, the treated wood industry is in major transition. Some current wood treatment technologies present familiar environmental problems, while less-toxic alternatives are just entering the market.
