Commercial Passive House Retrofit Tour in Brooklyn

On Sunday, November 11, tour a commercial Passive House retrofit of a 7000 SF
warehouse for the Hatzolah Central non-profit ambulance dispatch
service. See the project under construction as the ventilation system
and windows and doors are being installed. It’s conveniently located
near the 18 Ave F stop on McDonald Ave and 47th Street. The address is
1950 47th Street and I will be giving tours from 1:00-3:00. Coffee and
donuts courtesy of Zola Windows.

Gregory Duncan Architect is the acoustical and Passive House consultant on this project.

Passive House Tours November 10 and 11

Gregory Duncan Architect is proud to have three Passive House projects open for tours as part of the International Passive House Days on November 10 and 11.

Saturday, Nov 10:

Brooklyn, NY: Haus 96, the first condo building in the United States to be retrofit with Passive House components and methodology.

Sunday, Nov 11:

Westport, CT: Retrofit of a derelict, energy-guzzling single-family house designed in the International Style in the 1930’s by a disciple of Frank Lloyd Wright. “Their effort continues the spirit of technical innovation embodied by the original design,” according to the Westport Historic District Commission, which gave the house a Preservation Award.

Brooklyn, NY: Commercial retrofit of a 7000 SF warehouse for the Hatzolah Central non-profit ambulance dispatch service. See the project under construction as the Passive House windows and doors are being installed.

See the New York Passive House site for more tour information.

Tour Multifamily Passive House in Brooklyn

Haus 96, the first multifamily Passive House retrofit building in Brooklyn, will be open for guided tours on Saturday, November 10, 2012. This project proves that historic preservation, comfort, healthy indoor air, and dramatically reduced energy costs are compatible.

Duncan Architect performed the energy modeling for this project for architect Ken Levenson. Building science geeks may appreciate the following data:

  • Heat Demand 27 kWh/m²a
  • Cooling Demand 5 kWh/m²a
  • Primary (Source) Energy Demand 111 kWh/m²a
  • Airtightness 1.98 ACH50

Tour Energy-Efficient Home in Westport, Connecticut

On Sunday, November 11, 2012, there will be an opportunity for a guided tour of the Bauhaus Residence in Westport, Connecticut. Designed in 1934 by a disciple of Frank Lloyd Wright, the home was in dire need of renovation in 2011. The cast-in-place concrete structure is a striking example of the International Style in rural New England. Unfortunately the original concrete walls required a tremendous amount of energy to keep warm in the winter. In order to increase the energy efficiency and comfort of the house, architect Ken Levenson clad the entire building in ten inches of Foamglas insulation. With a passive solar hot water heating system, triple-glazed European windows, and an energy recovery ventilator, the award-winning project is going for Passive House retrofit (EnerPHit) certification. Gregory Duncan Architect performed the energy modeling and thermal bridge calculations required for certification.
