One of the most important design aspects to the owners was a copious amount of wall space upon which they could display their art collection.
Bohan and Mulligan both have environmentally oriented jobs, working for the Environmental Protection Agency and in Environmental Law respectively. “We got into the lines of work that we did because we have a very strong environmental ethic and wanted to carry it through all aspects of our life,” says Mulligan.They tasked Hine’s firm with the goal of building a house that “did not leave a carbon footprint,” and HMH Architecture+Interiors came through. This achievement includes a 10 kW solar intake system on the roof, floor-to-ceiling south-facing windows and a tight construction. In addition, they aimed to minimalize north-facing windows and incorporated overhangs to limit exposure to western sunlight.
Energy modeling prior to construction required the house to be built with fewer windows than initially intended. However, because of this and the other design features, the house produces 140 percent of its energy every year. Xcel has a program for eco-friendly houses that produce more energy than they use; there is an option to sell back that excess energy at the end of the year or allow it to roll over to pay off future years.
In addition to the eco-friendly nature of the house, there were many other design features important to Bohan and Mulligan. Highest among them was the family’s extensive art collection. “This was a tension in construction,
