On the Edge

UNDER NORMAL CIRCUMSTANCES, it would be hard to imagine a home on this site, high atop a cliff, surrounded by breathtaking views. But neither this home, known as the Zero Energy Idea House, nor its
architect, are of the average variety.

“It’s self-evident that this design is saying ‘I’m a different kind of house,’” says architect David Clinkston. “That was the intention—that you see the green roofs, PV panels, solar hot water panels and vertical axis windmill. These are all visible from the road. A ‘green wall’ at the main entrance (to reduce afternoon solar gain) is another clue that all is not ‘normal’ with this house.” The wall is a galvanized steel grid that will provide privacy when vines grow over it.

Not every aspect of the home’s infrastructure is obvious, of course. The structural  insulated panel (SIP) structure sits atop concrete grade beams that thrust back into the steep slope, and the below-grade wall at the back of the house was poured into ICFs.

The house is heated with a Warmboard radiant floor system—wood panels coated with reflective aluminum.

“That aluminum skin is thick,” Clinkston says. “with grooves that direct the heat exactly where you want it.”

The architect took the owner’s interest in “seeing the bones” of the home seriously, specifying a steel frame as the carriage for the SIPs.

2013 Green Home of the Year Awards
Educational Ecohome - Bozeman, Mont.

This unusual project home in Montana is being monitored to test various energy-saving strategies.

DUBBED THE REHAU® Montana ecosmart house, this project earned a HERS rating of 33—an essential feature for a 6,786-square-foot floorplan hoping to be taken seriously as a “green” project. The ecohome is being evaluated and studied by the Montana State University Creative Research Lab

(MSU CRLab).

The building envelope is built of both insulated concrete forms (ICFs) and structural insulated panels

(SIPs). The house features geothermal heat exchange and radiant cooling panels—along with solar thermal. For research purposes “the house design includes overlapping, interactive technologies [to monitor and in some cases, adjust] heating and cooling, fresh air intake and ventilation, insulation and the building envelope.”

An Internet-accessible HVAC-control system prioritizes based on likely performance, “choosing the greenest available energy first.” The radiant system and solar panels also extend to snow and ice melting.

In 2014, the homeowners will move in. Data collection, comparison and analysis will continue for several months, in order to verify conclusions reached during the research phase.
