This unassuming home located in Whitefish, Montana has the performance characteristics of a top of the line sports car. The double-stud exterior walls, triple pane glazing, insulation and mechanical system allow this building to out run anything in the neighborhood. The custom home was one of ten homes in a pilot study program through Northwest Energy Efficiency Alliance (NEEA). It was monitored for energy usage, humidity and the quality of indoor air for a period of two years after completion. A few interesting components in the construction of the home include: drain-waste heat recovery, heat recovery ventilation, super insulated building envelope and carefully chosen sustainable finishes.
