Window Shades, Blinds, and Awnings | GreenBuildingAdvisor.com
Some excellent ways to reduce solar heat gain without spending a ton of money on new windows.
We use windows to give us views, fresh air, and passive solar heating in the winter, but are there good ways to modify them to prevent too much solar gain in the summer? Yes, and new research from BuildingGreen (my company) and Lawrence Berkeley National Lab (LBNL) tells us which “window attachments” are worth using.

Product Review: Daylighting & Skylights – Daylighting, Skylights – EcoHome Magazine
Homeowners love to let the sun shine in.
But builders and architects know that flooding rooms with natural light—through windows, skylights, solar tubes, light wells, clerestories, and other building-envelope penetrations—can create problems, especially in northern and southern regions where heat loss or heat gain often accompany any increase in glazing. Bringing natural light deep into a home’s interior, whether for new construction or renovation, also can require difficult and costly building efforts but can reap huge rewards in efficiency and comfort if implemented effectively.

Air Leaks or Thermal Loss: What’s Worse? | GreenBuildingAdvisor.com
Beefing up R-values and reducing air leaks are the twin rallying cries of builders focusing on energy efficiency. Regardless of the particulars of the house design, more insulation and fewer air leaks make houses more comfortable, more durable, and less expensive to heat and cool.

A Slow Economy Doesn’t Change the Rules of Bidding – Fine Homebuilding Article
Contractors say that too many homeowners and architects are naive in their reliance on the bid process as the major tool to lower project cost, and that they ignore the negative impact this process can have on the quality of construction, the level of service provided, and the development of the trust needed among all the parties for a successful outcome. If builders see that a bid process is not supported by thorough drawings or structured to ensure that all bidders develop accurate costs, they feel competitive pressure to provide lower bid figures that increase the chances of getting the job rather than finishing it the way the owner intends.

Building with a Shade of Green in North Charleston
The future of construction is focused on a color we’ve all heard a lot about. The Sustain South Carolina 2010 conference is focused on all things green from reusable material to better building practices. Tim Kottyan is the green design manager for Harris Construction. “The core philosophy is doing it right. Doing it sustainable and justifying the cost up front for the savings in the end,” he said. “Green building and changing the environment we live in cannot start with one building. Although it’s a start, this needs to be part of a community effort,” said John Hansen who helped organize the two day event. He says countless jobs will also be created though the green building movement.

Residental LEED Projects Already Surpass Commercial Projects in Total Certifications
Interesting that LEED for Homes is outpacing the commercial version.
I noticed a while back from the USGBC updates that residential certifications were quickly catching up to their commercial counterparts. A USGBC Update from 03.11.10 there are now 5,000 ‘residential’ certifications and 4,890 commercial projects in existence, though there are still slightly more commercial registered projects… amazing growth considering the first LEED-NC system was released over ten years ago while LEED-Homes was only launched in April of 2009…
