After months of development, LEEDuser (which is powered by BuildingGreen.com) has added direct support of LEED for New Construction version 2.2 (LEED-NC v2.2). That means that you can access support to all LEED-NC v2.2 credits using LEEDuser's credit browser, and through our directory of LEED credits. For every credit in the LEED-NC v2.2 system, you can read our quick overview page with a diagram view of the credit, use our "Getting It Done" checklist of steps to earn the credit, view the verbatim

Continuing a trend of more efficient LED lights, Philips this week unveiled its LED replacement to the 60-watt light bulb.

LEDs are light-emitting diodes. Many experts look to LEDs as the future of lighting. Unlike compact fluorescent lamps (CFLs), metal halide, and induction lamps, LEDs do not contain mercury, which is a toxic metal and disposal concern.

Fiber optics, that miracle of modern communications, can also be used to deliver natural light to spaces deep in a building. Last week I focused on tubular skylights, which provide a great way to bring daylighting into home offices, hallways, bathrooms, and other spaces.

Welcome to our new blog dedicated to the issues of water, water efficiency, and water policy.

When we talk about the environment and environmentally responsible building, it’s almost always energy that takes the spotlight, with water pretty far down the list. But it’s not hard to see just how much of a back seat driver water can be:

Following John Manville's switch to a non-formaldehyde acrylic binder in 2002 and Knauf's 2009 introduction of its EcoBatt fiberglass insulation made with biobased binder instead of phenol formaldehyde, CertainTeed has introduced its own answer to the green fiberglass insulation trend.

The company began shipping Sustainable Insulation? on a limited basis in California and western Canada at the beginning of March this year and will expand the distribution over time.
