Doing LEED SSc8? Light pollution reduction in a nutshell.
by
The following is a video that we recorded at our booth at the 2009 Greenbuild conference, when we transformed BuildingGreen's booth into the "Ask LEEDuser" experience, including talks on specific credits from LEEDuser's "guest experts"--the top LEED minds on specific LEED credits.

Green Building Myth #2: It's All About Materials
by
Last week I wrote about one of the common myths of green building: that it has to cost more to build green. This week, I'll tackle another myth: that green building is mostly about materials.
Knoll Provides FSC Wood as a Standard Feature
by
We've been writing about the Forest Stewardship Council (FSC) in Environmental Building News since the organization was created in 1993. We've watched as FSC pushed the mainstream forest products industry toward more responsible forestry practices even as that industry fought to prevent or slow the adoption of the U.S. Green Building Council's LEED Rating system because it awarded points for use of FSC-certified wood exclusively.
Green Building Myth #1: Does Green Building Have to Cost More?
by
| Even if a small house has lower levels of insulation than a larger house, it's likely to cost less to heat. 1. R-19 walls, R-30 ceilings, double-low-e (U=0.36) vinyl windows, R-4.4 doors, infiltration of .50 ACH, and R-6 ducts in attic; 2. R-13 walls, R-19 attic, insulated glass vinyl windows, R-2.1 doors, infiltration of .50 ACH, and uninsulated ducts; 3. Natural gas at $0.50 per therm; 4. Electricity at $0.10 per kWh. |
Having written about green building for more than twenty years now, I've encountered lots of misperceptions.

Cree's Par 38 LED Lamp a Winner (but expensive)
by
Back in 1990, when I built a new garage and office space at my home in Dummerston, Vermont (where BuildingGreen started out), I installed two sections of Lightolier lighting track with dual switching for use of whatever screw-in lamps I wanted to use in can-type fixtures as well as exposed sockets. During the twenty years since, this has been my little testing laboratory for state-of-the-art energy-saving lamps.
Ground-Source Heat Pumps
by
Despite being highly efficient at turning kilowatt-hours of electricity into heat or chilled air, ground-source heat pumps have a significant drawback and usually aren't the best heating system choice.
Exciting Developments at Marvin Windows

Wandering around the trade show at Better Buildings, my attention was caught by several cut-away window corners at the Marvin Windows & Doors booth.
Home Wind Power

The 30% federal tax credit for residential wind turbines (with no upper limit) opens the door to scams, which could tarnish the reputation of the wind energy industry
