475 On-Site: Cornell Tech Details

Deborah Moelis of Handel Architects Shares Designs Of The World’s Tallest Passive House

4The Cornell Tech residential tower project has been widely covered in the media – from The New York Times to The Wall Street Journal,  Treehugger and The Atlantic. But those stories have only scratched the surface. As a company dedicated to providing in-depth information to professionals, we were hungry to dig in and share detailed knowledge.  And Deborah and the team at Handel Architects, in keeping with the spirit of the Passive House movement, have been very forthcoming in sharing their process and opinions with the architectural community.  As Deborah states in the video below, “We are looking to change the way buildings are built… Any New York City Housing project should absolutely be going this route, there is really no question.” We at 475 couldn’t agree more, and we can’t wait to help architects and builders across North America make it happen.

We’re very proud that INTELLO Plus is providing the interior airtightness and vapor control for this project. As we do with many of our customers, 475 worked closely with project team to help create details that solved design problems and worked with the needs of the project.  And from the acknowledgement of Passive House standards in New York City’s building plans, to Mayor de Blasio’s supporting statements at the Cornell Tech groundbreaking ceremony, we’re seeing high hopes for low-energy building design.

Recipe for the Cornell Tech Passive House air barrier

  • INTELLO Plus – Membrane providing continuous interior airtightness and smart vapor control
  • TESCON VANA – For sealing INTELLO Plus membrane seams
  • TESCON PROFIL – For airtight connections around windows and doors
  • CONTEGA SOLIDO SL – For sealing INTELLO Plus connections to masonry and metal
  • ROFLEX gaskets – Quick, easy, and robust airtight EPDM gaskets for around pipes
  • KAFLEX gaskets – EPDM gaskets, similar to ROFLEX for around wire and cable penetrations

As you can see, the above material list is no different than the list we would provide for a tiny house. It’s simply a matter of scale.
