the prescott passive house by studio 804all images courtesy studio 804

he prescott passive house by studio 804 is the product of eight months of research, experimentation,design, and construction by the architecture studios sixteen graduate students at the universityof kansas. located in kansas city, kansas, the single-family home is designed to both LEED platinumand passive house standards.

he house acts as a prototype for the region, as it aims at being the first certified passive housein the state of kansas, and one of only a handful in the country. to obtain its goal of a 90%reduction in heating and cooling energy demand, the house uses low cost passive strategiessuch as louvers, thermal mass, high performance windows, super insulation, southern orientation,

and an air tight building envelope. an energy recovery ventilator works in conjunction with thesestrategies to temper fresh intake air with energy from the exhaust air, providing constant freshair year round.

louver detail

he 1,700 square foot, three bedroom, two bath residence bestows many amenities withina small ecological footprint. despite its modest size, the open floor plan creates a spacious interior.a double height living room connects the main floor with the upper level, where the master bedroom is located. the stacked master bathroom and main floor bathroom are flooded withnatural light through an internal two-story frosted glass wall across from the expansive southernglazing. overlooking the living room and southern array of windows is the flexible loft space.on the main level, the living room is connected to the kitchen and dining spaces with an exposedconcrete thermal mass floor, while a change in overhead height articulates the different spaces.hese living areas are located just off of the 400 sf deck, which lends uninhibited views of he prescott neighborhood and the kansas city skyline while doubly functioning as the carport roof.

at the west end of the main level are two additional bedrooms with views to the surroundingdouble width lot. while remote controlled operable skylights create the only break in the northernenvelope of the house, operable glazing stretches the entire length of the southern side to encouragenatural ventilation. this impressive faade is protected by louvers optimally angled to allow winter heat gain yet block sunlight from penetrating the house in the summer. downstairs, a full walkoutbasement provides ample storage as well as a finished flex room located directly off of the carport.

the front of the house

a 16 inch thick insulated wall assembly and a 22 inch thick insulated roof assembly providehe basis for a home that seeks a 90% reduction in heating and cooling energy. the airtight

assembly nearly eliminates nearly all heat transfer through the building envel ope, kee ping all heatgained from the high performance glazing within the house. the energy recovery ventilator and thermal masses seek to further maintain a constant interior temperature, reducing nearly allneed for additional tempering support. outside, clotheslines discourage the use of an electricclothes dryer, one of the most inefficient of the otherwise energy star rated appliances.in the spirit of the age-old japanese shou-sugi-ban tradition, the exterior of the prescott passivehouse is clad in a charred douglas fir rainsc reen. this low-maintenance assembly yields a UVprotected dark black fini sh to the house. re cycle d paper w indowsills and countertops,bamb oo fl ooring, and concrete thermal ma ss floo r comple me nt the clean white interior wallsand ceiling.
