MinnePHit Passive House Retrofit, Brazelton Residence – Minneapolis, MN (USA) (Passive House project database ID 2069) http://www.passivhausprojekte.de/#d_2069 Technical drawings in this document are not drawn to scale. 1 ABSTRACT



1.1 Data of Building The MinnePHit Passive House Retrofit is a single-family home located in Minneapolis, Minnesota (USA) that was gut & retrofit to the (at the time) new EnerPHit standard. Based on the Passive House Institute’s EnerPHit moniker & its Minneapolis locale, the clients coined this project the MinnePHit house. The final design included demolition and reconstruction of a small part of the footprint, a small addition, many different wall sections, a fully updated and upgraded building envelope, and new interior finishes throughout. Construction was completed in 2011-2012. The project is North America’s first certified EnerPHit project & the first certified Passive House Retrofit in a very cold climate in the world. Special features Working with the structure of the existing house Fully updated home fits within historic neighborhood fabric Earth-friendly interior and exterior finishes throughout Automated continuous ventilation system with over 90% efficiency Successfully fit complex client program into small amount of space Year of construction 2011-2012 U-value exterior wall (avg.) 0,11 W/(m²K) U-value basement slab 0,17 W/(m²K) U-value roof 0,073 W/(m²K) U-value window 0,77 W/(m²K) Effective heat recovery 89%

PHPP annual heating demand 27 kWh/(m²a)

1.2 Brief Description The MinnePHit House is a 5-bedroom, 3-bath, 185m2 home that began as a 3-bedroom, 2-bath, 128m2 home in Minneapolis MN. Commissioned by a private client, this home is the first certified Passive House EnerPHit in a very cold climate on the planet. It sits on an urban lot in an established neighborhood, near parks and trails and the historic Minnehaha Falls. With solid structural underpinnings but significant performance and size challenges for a family of five and two large dogs, the existing home was a prime candidate for a Passive House EnerPHit pilot. It demonstrates the amazing potential of high-efficiency retrofit design for existing homes in a cold climate. Find more about this project at http://testudio.com/projects/minnephit-house/.

3 BUILDING SECTIONS

S-N Building Section @ Retrofit S-N Section @ Addition N-S Section @ Entry

E-W Building Section @ Stair The building envelope of the MinnePHit house is more diverse than most in effort to work seamlessly between new and existing assemblies. The basement slab was removed to insulate underneath a new concrete slab with rigid EPS foam. South and West below-grade exterior walls were excavated and insulated with rigid EPS applied to the exterior and closed cell spray foam from the interior for air barrier, while North and East below-grade walls received closed cell spray foam from the interior only for both insulation and air barrier, as excavation at these walls was not feasible. All new and existing above-grade exterior walls received new sheathing and i-joist framing added to the outside with dense-packed cellulose insulation, and the home has a completely new roof truss package that was meticulously air-sealed and insulated with loose-fill cellulose. New durable fiber-cement siding and Passive House windows complete the exterior package, and the result is a continuously air-sealed and insulated envelope that provides an efficient and comfortable interior in a cold climate year-round.

The building envelope of the MinnePHit house comprises a combination of existing and new assemblies. Connection details at interior walls and floors do not present a protrusion of the airtightness or insulation layers. Above grade walls, typical All existing 2x4 walls are insulated with batt insulation. OSB sheathing is added to the existing sheathing, which is taped at seams and transition details to provide the air barrier. 9 ¼” [235mm] I-Joists are fastened to the existing studs. The newly created cavities are dense packed with cellulose providing an overall R-Value of 44 [Usi =0.128 W/(m2K)]. Permeable fiberboard sheathing allows for drying potential to the outside. The new fiber cement board siding is mounted to furring strips (ventilated rainscreen) and gives the house a durable new façade that fits well with the historic original house and surrounding neighborhood. Below grade walls, typical 6” [152mm] of EPS is added to the outside of the existing 11 5/8” CMU walls where accessible (South and West sides). On the inside 2” [51mm] of closed cell spray foam provide the air barrier. On the North and East sides excavation is not possible, thus 4 ½” closed cell spray foam on the inside provide the air barrier and insulation in these areas. The below grade walls offer an R-value from 32 [Usi =0.176 W/(m2K)] to 41 [Usi =0.138 W/(m2K)]. Basement stair wall Due to space restrictions at interior and inability to excavate at exterior, the below grade wall adjacent basement stair is insulated to the inside with Vacuum Insulated Panels glued to the block wall, taped at seams to provide the air barrier and covered with drywall. The R-value for this assembly is 26.9 [Usi =0.211 W/(m2K] and is factored into the typical below grade average above. Slab The existing slab was removed and ground excavated to the bottom of the footing. A new 4” concrete slab sits over 6” [152mm] of EPS insulation and two layers of 6 mil polyethylene membrane—taped at seams and transition details, which provide the air barrier. The new slab offers an R-value of 26 [Usi =0.219 W/(m2K)]. Footing Existing footings are insulated with rigid EPS to the exterior where excavation occurred, and new footings have rigid EPS at interior and exterior as well as underneath. Roof The existing roof was removed. The new roof is a cold roof finished with asphalt roofing. The 2nd story ceiling is insulated with 22” [559mm] of loose fill cellulose providing an R-value of 76 [Usi =0.074 W/(m2K]. The underside of the trusses is sheathed with OSB taped at seams and transition details providing the air barrier. A suspended ceiling houses lighting and the ventilation ducts.

6 DESCRIPTION OF THE AIRTIGHTNESS LAYER; INCLUDING TEST RESULTS Two layers of polyethylene membrane, which are sealed and taped at connections and protrusions, provide the airtightness of the basement slab. Below grade exterior walls’ airtightness is achieved with between 2-1/2” and 4-1/2” of closed cell spray foam insulation applied to the interior side. Above-grade exterior walls both new and existing are clad in a layer of OSB sheathing, taped at seams and transition details, which provides the airtightness. The underside of the new roof trusses is clad with OSB taped at seams and transition details, again providing the air barrier. Windows and doors are sealed with tape. Protrusions are caulked and foamed. The Energy Conservatory with the help of the Tectite software using the prescribed DIN EN 13829 protocol performed the pressure test. The building averaged 195 CFM50, for depressurization and 197 CFM50 for pressurization for an average of 196 CFM50 or 0.65 ACH50.

7 VENTILATION LAYOUT The ventilation system in the MinnePHit House revolves around a Paul Novus 300 HRV from Zehnder. It provides balanced ventilation with a rated heat recovery rate of 93%. An electric resistance pre-heater keeps the ventilator frost-free. The duct system is home run. Outside air is supplied to living spaces and bedrooms, exhaust air returned from the kitchen, baths, and mechanical space. Adjustable diffusors are used to control air volumes. A common wall in the center of the home is used to keep vertical runs and overall duct lengths short. The ventilation machine is installed in the Workout / Mechanical room in the basement level adjacent the common wall that runs through all levels. Air intake and exhaust pipes connect straight through the wall. Basement level ventilation plan

Zehnder Paul Novus 300 HRV Zehnder ComfoDuct insulated exhaust

Zehnder ComfoTube supply and return ducts The ventilation system was laid out by TE Studio and commissioned by Zehnder. The ventilation machine offers a summer bypass to maximize passive cooling when available. Central Unit: Zehnder Paul Novus 300 Type: HRV Specific Values: 93% heat recovery/ 0.24Wh/m3 electric efficiency



8 HEATING STRATEGY The heat load for the home (approx. 4 kW) is delivered by an existing natural gas boiler connected to hydronic in-floor heat and the domestic hot water (DHW) system. It’s efficiency is rated at 84%. The roof is engineered to receive a Solar thermal or PV system at a later date to further reduce the primary energy demand. The DHW system is home run.

11 DESIGN OVERVIEW The building was designed from the outset to solve programmatic and spatial challenges while meeting EnerPHit criteria. The first PHPP was completed during schematics as a tool to explore the bounds of the retrofit and present potential opportunities to the clients, and was subsequently kept current with design evolutions. The construction methods were selected specifically with airtightness in mind, as the local building industry does not have a lot of experience with airtight buildings, especially in a retrofit application. Fenestration and glazing were fine-tuned using the PHPP. In an effort to deliver a holistic and sustainable design, specifications were guided by their impact to indoor environmental quality and occupant health, water conservation, resource efficiency, site and community impact as well as comfort and energy performance. The home was designed by Dipl.-Ing. Tim Delhey Eian of TE Studio, Ltd. with the help of Barbara Schmidt of Studio BStyle (interior design). 11.1 Technical Design The technical systems were designed by Dipl.-Ing. Tim Delhey Eian of TE Studio, Ltd. 11.2 PHPP Modeling & Calculation The PHPP modeling was done by Dipl.-Ing. Tim Delhey Eian of TE Studio, Ltd. The Passive House Institute of Darmstadt, Germany certified the building. Wolfgang Feist of the Passive House Institute in Darmstadt issued the EnerPHit certificate on 10 January 2013. 11.3 Structural Engineering Eric Bunkers, P.E. of Mattson Macdonald Young provided structural engineering for the project.
