A Passive House in the Big Apple

A Passive House in the Big Apple

A new project is underway in NYC, and while it certainly won't be the city's first modern structure, it is hoping be the first certified Passive House. The mixed use building will be so efficient that the designers boast even without any solar panels, the home will use very little energy.

The ambitious project is the work of New York-based architecture firm, Loadingdock5. To achieve the Passive House certification the building primariliy relies on a lot of insulation, a continuous air seal, solar gain and super efficient windows. The building also benefits from its location — it's an interior lot with adjacent heated walls from the building next door, so has the advantage of having less overall heat loss.

Primary Passive House Design Features:

  • Walls: Load-bearing 8" concrete masonry units with 7" EPS exterior insulation
  • Parapets: Autoclave aerrated concrete blocks to avoid thermal bridging
  • Exterior Finish: EIFS dark grey
  • Interior Finish: CMU painted, all electric installation exposed
  • Roof: 4" concrete on steel deck covered by 8" XPS insulation
  • Windows: Reversible window from Walch in Austria
  • Residence Entry Door: Custom 3" thick wood panel
  • One 1.5 tons Mitsubishi Mini Split Heat Pump ducted indoor unit for heating and cooling demand
  • Zehnder ComfoAir 350 Enery Recovery Ventilator
  • Exterior blinds at the south facade to avoid summer overheating

Loadingdock5 is already working on their second Passive House project, which as a renovation will certaintly be even more challenging.
