4 Project Details 118 units of affordable, workforce housing (for incomes at or below 60% AMI) Development team includes Newport Partners, Landon Group, LHB (architects) and Precipitate (architects) Two apartment buildings with 59 units each Same number and mix of unit types in each building: 50% 1-bedroom, 50% 2-bedroom and 3-bedroom One of the two building will be conventional construction The other building will have Passive House elements

5 What does Passive House mean? Let s break that down: Passive

11 Passive Principles Minimize Loss/Gain Continuous Insulation Air-Tight Construction Proper location and durability of air barrier and vapor retarder High Performance Windows/Doors Optimize solar gain and shading Minimize overheating in winter Balanced Ventilation (ERV) Minimized Space Conditioning

13 Passive building comprises a set of design principles used to attain a quantifiable and rigorous level of energy efficiency within a specific quantifiable comfort level. Maximize your gains, minimize your losses.

14 A passive building is designed and built in accordance with five building-science principles: Employs continuous insulation throughout its entire envelope without any thermal bridging. Uses a building envelope that is extremely airtight, preventing infiltration of outside air and loss of conditioned air. Employs high-performance windows (typically triple-paned) and doors. Uses some form of balanced heat- and moisture-recovery ventilation and a minimal space conditioning system. Manages solar gain to exploit the sun's energy for heating purposes in the heating season and to minimize overheating during the cooling season.

15 Passive building principles can be applied to all building typologies from single-family homes to multifamily apartment buildings, offices, and skyscrapers. Passive design strategy carefully models and balances a comprehensive set of factors including heat emissions from appliances and occupants to keep the building at comfortable and consistent indoor temperatures throughout the heating and cooling seasons.

16 So where is the Hook & Ladder Passive House project?

17 It s in MINN-uh-SO-da

18 Here are our counties. We ve got a bunch of em.

19 The Hook & Ladder project is in the 7- county metro area, which includes the Twin Cities of Minneapolis (the largest city in the state) and St. Paul (the state capitol).

20 This shows the major regions of the City of Minneapolis. The Hook & Ladder project is in Northeast Minneapolis (shaded in yellow)

21 Northeast Minneapolis is a gathering place for the City s artists and art-related businesses

27 Hook and Ladder s site plan includes both private and public open space. The southern portion of the site features green space set back from the buildings and adjacent to a public trail. Place-making components will be incorporated, including public art, landscaping, and seating. An open space in the middle of the site will serve the apartment residents. The building interior will include exhibit space for artists residing at Hook and Ladder. Tenant common space will include an exercise room, management office and both indoor and outdoor gathering spaces. Hook and Ladder will incorporate sustainable, energy-efficient building techniques far beyond conventional affordable housing. One of the two new buildings will be designed to achieve Passive House (PH) certification. The buildings will be nearly identical in floor plans, unit mix and tenant population. This will provide a long-term, side-by-side analysis of the cost benefits of PH.

37 Brownfield Grants What is a brownfield? The term brownfield site means real property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant. --Section 101 of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (42 U.S.C. 9601)

47 Passive Principles Minimize Loss/Gain Continuous Insulation Air-Tight Construction Proper location and durability of air barrier and vapor retarder High Performance Windows/Doors Optimize solar gain and shading Minimize overheating in winter Balanced Ventilation (ERV) Minimized Space Conditioning

48 Massing Minimizing surface area minimizes opportunity for heat transfer However, a narrower building will have better access to daylight and opportunity for solar control

49 Orientation Control how the sun interacts with your building Generally, a building with an east-west axis (+/- 15 ) allows for control of southern sun and minimizes east and west sun exposure north

50 Air-Tight Construction Top strategy for reducing energy consumption, but difficult to achieve Blower door tests before insulating aid in finding gaps PHI pa PHIUS cfm/sf 50 pa Holtkamp Heating & A/C, Inc. DOE site

51 Windows Size+Placement Glazing used for solar gain should be located on south, with less glazing to north, east, and west

52 Windows - Shading High summer sun is blocked from entering Lower winter sun enters windows, where it warms the space Sun must be stopped before it hits glazing interior blinds are not as effective summer winter

53 Windows Type Minimize U-Value (comfort vs. heat loss) Maximize Solar Heat Gain Coefficient on South

54 Energy Recovery Ventilation (ERV) Airtightness requires ventilation even when outside conditions are not ideal ERVs transfer heat to or from makeup air depending on the season Minimize space conditioning Michelle Penn, AIA Authenticity, LLC
