Roling Passive House

ROLING PASSIVE HOUSE The project is a play on rural development with an assembly of buildings whose distances apart create an entry sequence, outdoor courtyards concealing and revealing views of a lake, and gardens. The home is designed to meet the PHIUS Passive House standard and be near net zero. More coming soon...


PH02:BRK In the fall of 2018, RAd studio led a graduate design studio through all phases of design of a single family residence capable of meeting the high performance energy standard of Passive House Institute United States (PHIUS). The project builds on the research developed in PH01. The team completed a full construction document set, research and documentation, specifications, WUFI energy modeling, THERM modeling, as well as the graphic output presentation materials. The narrow infill site sits between a traditional house to the north and PH01 to the south. Numerous studies in section, plan, and axon were completed to embed the activities of the house in its context as well as to ensure enough access to light and heat gains. Due to the narrowness of the lot and PH01 shading much of the narrow lot’s access to winter solar heat gains, numerous forms and layouts were tested with WUFI energy modeling outcomes. A dormer pops-up on the south, serving as an open lightwell in section for the stairway inside and providing enough heat gain to allow for PHIUS certification. The additive front porch component borrows more from traditional houses in the neighborhood but is articulated as a cantilevering porte cochere […]

PH01:BRK Passive House

PH01:BRK Passive House SDSU DoArch has been awarded a Future Funds grant by the Governor’s Office of Economic Development to integrate curriculum using relevant technologies specified by U.S. Passive House Standards. The initiative is an ongoing, self-sustaining, and collaborative effort led by student design teams. The grant provides for training, research, and monitoring of new and existing Passive Houses.Students are working in collaboration on many aspects involved with the design. In addition to the graduate studio, building workshops, seminars, and technology courses have been offering instruction supporting this project and energy-conscious construction in general.

Urban Infill

URBAN INFILL HOUSE In the historic All Saints neighborhood just south of downtown Sioux Falls, SD, a young family purchased a lot for an urban infill project. The simple massing ties to the neighborhood as does the roof slope and the garage on alley side with a courtyard between house and garage. A survey of the various columns on the houses provided inspiration for the 3 bay, 4 column "Georgian" stacked front porch, translated here into privacy slats with large openings for views of the street and toward downtown. A new column type was added to the neighborhood's pallette with a slender steel I-beam column system. Passive House strategies are used to drastically reduce energy use. The home is framed in oversized ICF and SIP construction to achieve a near airtight structure. A whole house ventilation system provides fresh air throughout the year. The design nearly qualifies for passive house certification and is enery star and net zero ready capable. In addition, the home is designed to age-in-place and be readily adaptable if living is required on one level.
