The Center for Neighborhood Technology (CNT) conducted a post-occupancy study of 25 LEED commercial projects in Illinois and just published the first round of results from their research. The Regional Green Building Case Study Project is one of the first post-occupancy studies to measure energy performance, greenhouse gases emissions, water use, transportation effects, construction and occupancy costs, health benefits, and occupancy comfort on a regional scale. Although CNT found that some LEED projects perform better than others, they also determined that investing in energy efficiency pays off.
The visitor center at the Bernheim Arboretum in Clairmont, Kentucky, which was completed in 2005, continues to garner attention. In 2007, it was awarded LEED Platinum certification. Most recently, the visitor center has received the EPA's prestigious Lifecycle Building Challenge Award. This is the third year that the EPA has held the challenge where entrants are judged on their building's ability to minimize waste, reduce energy consumption, and be disassembled for material reuse. The visitor center took an award in the Building–Professional Built category and an Outstanding Achievement Award for Best Greenhouse Gas Reduction.
It's time to follow up on a project a cool project, the Zero Energy Idea House, that we mentioned at ground breaking in July 2008. Located at Bass Cove near Bellevue, Washington, the 1,630 square-foot, two-bedroom Zero Energy Idea House was designed by Clinkston Brunner Architects and built by Shirey Contracting. Overlooking Lake Sammamish, the home is planted into the hill as a demonstration of energy efficiency — the goal is to show that it generates as much energy as it uses.
Since we first mentioned Stillwater Dwellings in March, the new company has been extremely busy. Not only have they lined up plans to build green prefabs in Portland (Or.), Santa Barbara (Ca.), and Healdsburg (Ca.), but they’ve recently completed their first prefab home in Bend, Oregon. The company was kind enough to send us a few photos of the inside and outside, and the modern home is just stunning.
We've seen all kinds of LEED Platinum homes — manufactured, prefab, traditional, and modern — but this is the first LEED Platinum log home that we've seen. It's likely the first LEED Platinum log home in the country. The home was designed by Eric Hughes of Image Design LLC, and built by Hybrid Homes LLC out of Muskegon, Michigan. Located on 6060 Longbridge Road in Pentwater, Michigan, the green log home features a number of green elements:
