Frog Hill, a 3,655 s.f. residence in Washington, Connecticut, has achieved certification under the LEED for Homes Program! This was accomplished through exemplary use of environmentally preferable building materials and pest control alternatives, and a design that is predicted to perform 35% better than code based on energy simulation and diagnostic pressure testing of the home after construction. Among the home’s energy-conserving Click to Read More

Connecting Nature to Design

Posted by on 5/18/12 at 02:19pm

What are the Bottom Line Benefits of Biophilic Design? How can our designs more effectively connect with Nature? These are some of the questions being discussed at this year’s AIA Convention by a panel including Jason McLennan, founder and creator of the Living Building Challenge, William Browning, partner of Terrapin Bright Green, and Bob Berkebile, founding principal of BNIM Architects. Read a short article about this panel’s discussion here.

Material Testing

Posted by on 3/28/12 at 03:41pm

About a year ago, Bob and I nailed two samples of Cambia wood siding to a south facing exterior wall of Jamey Garza’s studio compound in Marfa. After a year in the desert sun, through the diurnal fluctuations of temperature, the sample looks almost the same as a year ago. Cambia is a thermally modified wood (domestic and FSC). This treatment improves the dimensional stability and decay resistance of the wood. We plan to use Cambia on the Kruger’s deck and hope it performs the same way! Click to Read More

BEYOND LEED REGENERATIVE DESIGN: A SYMPOSIUM JANUARY 27 + 28, 2012   Friday, January 27, 2012 Beyond LEED Session   Beyond LEED.   EVOLVED.   Following previous discussions with Bob Harris (Lake|Flato) and Bob Berkebile (BNIM), a few questions kept coming to mind: Why aren’t there more living buildings? Why are they NOT being pursued, built and dreamt about? Click to Read More

We performed some energy modeling studies a few years ago to determine what the ideal effective aperture is for each climate we work in. We were surprised to find that because energy codes and window manufacturers are tightening up on glazing solar heat gain performance, code-minimum windows do not allow for passive solar heating benefits. This means that even in northern climates where buildings could benefit from southern heat gain, Click to Read More

The first LEED project of 2012 has arrived! We just received the official word from USGBC that Miller Porch House earned LEED Silver. This is our 12th LEED project to date. Congratulations to the project team, and special thanks to Tenna who did the heavy lifting on the LEED documentation. Click to Read More

Rainwater Calculator

Posted by on 11/28/11 at 11:00am

SIMPLE RAINWATER CALCULATOR to help you estimate how much water you can potentially collect and how much water your design requires (both indoor and outdoor). As you progress through design there are other consultants who will likely provide input such as the landscape architect, irrigation designer, and civil engineer. Click to Read More
