Energy-Efficient Garage Doors

Posted on February 12, 2010 by Martin Holladay, GBA Advisor in Musings of an Energy Nerd

If you’re shopping for a garage door, the door’s energy performance may not matter — especially if you don’t heat your garage. However, there are a few reasons why you might be looking for a well-insulated, draft-free garage door:

Get Ready for a Green Building Ordinance

Posted on February 11, 2010 by Michael Chandler, GBA Advisor in Green Building Blog

A few years ago, I — along with Michele Myers (the "God-Mutha uv Green") and representatives from county government, planning and inspections staff, architects, remodelers, production builders, commercial builders, utilities, lawyers and business leaders — got together at the behest of our local planning board to work on developing a green building ordinance for our county.

The Construction Process – Part 1: Building Assessment

Posted on February 10, 2010 by Peter Yost in Green Communities

Amy and I are going to tackle the construction/renovation process, broken down into six components:

1. Building Assessment
2. Contractor Selection
3. Project Scoping
4. Project Documentation
5. Implementation/Construction
6. Commissioning/Homeowner Education

Keep in mind that each of these will be presented from the green building context we laid out in our last blog: emphasis on overall resource efficiency, process not just products, and maintaining if not improving the health and safety of occupants.

It’s OK to Skimp On Insulation, Icynene Says

Posted on February 5, 2010 by Martin Holladay, GBA Advisor in Musings of an Energy Nerd

While energy experts often advise builders to exceed minimum code requirements for insulation, Icynene Incorporated, a manufacturer of open-cell spray polyurethane foam, is swimming against the tide. Surprisingly, Icynene is trying to convince builders to install less insulation than the code requires.

Will Solar Panel Mounts Cause Roof Leaks?
