Program: At an elevation of 7,000 feet, 125 Haus is a 2,400-square-foot residence for German architect Jörg Rügemer’s family of four in Park City, Utah. The three-story house, completed in October 2011 for $282,600, contains three bedrooms, two bathrooms, living and dining spaces, and a studio and garage on the basement level. Rügemer, an architecture professor at the University of Utah since 2006, wanted to employ strict German energy standards to create one of the most energy-efficient residences in Utah.
Solution: Rügemer conducted energy simulations throughout the design phase, adjusting the building configuration, wall systems, and materials to optimize performance. With a façade of stucco and cedar, the house has a double stud wood frame that is insulated with 11 inches of fiberglass. It also contains high-performance windows (U-values between 0.14 and 0.20) that are extremely airtight (0.8 ACH50). The large south-facing windows provide passive solar heat on sunny days. The house is also equipped with a heat recovery ventilator, an on-demand hot water heater, and a direct-vent gas fireplace for cold nights and gloomy days, eliminating the need for a standard furnace.
The architect has continued to monitor energy usage post occupancy; the house is 80 percent more efficient than a standard residential building built to code in the same location. The average monthly energy bill for heating and cooling is $22, totaling $265 per year.
