125 Haus
Located at an elevation of 7,000 feet in Park City, 125 Haus is a 2,400 SF three-bedroom plus studio single-family residence for a family of four. Goal was to design and develop a project for a highly energy-efficient, sustainable residential case study that would be priced at market rate, at the same time providing high-end contemporary, multifunctional spaces for the family of four. Employing an integrated planning process, 125 Haus was designed to the strict German Passive House standard. To optimize design and predict the building’s energy performance, PHPP Passive House Planning Package and 3rd party DOE EnergyPlus energy simulations were conducted during the design phase. The results were used to adapt the building to its specific site conditions, to test different design configurations, wall systems and components, and to optimize performance with regard to efficiency and costs. Verified by 26 months of Post-Occupancy monitoring, 125 Haus is more than 80% energy-efficient than a comparable build to code-standard residence in a similar location. Annual heating and cooling bills for natural gas and electricity add up to $265, or $22/month, which was achieved through means of passive design only (no renewable systems are installed in the building to this point).
