Wayne Turett’s Dream House

1024 768 The Turett Collaborative

A few years ago I started to see more information on Passive Houses in a number of architectural journals. The concept was simple, design a house that was very well insulated and sealed allowing very little infiltration that would reduce the demand for heating and cooling. That was the way I understood it. Perhaps I oversimplified it in my mind.  Unlike LEED, which takes many other factors in consideration, Passive House was a much more simple recipe for a very efficient house. In this journal, I will attempt to tell you my experiences as I realize a long held dream of building my own Passive House to live in. A little background: my wife, Jessica and I purchased a property in Greenport, on the North Fork of eastern Long Island, a couple of years ago with the purpose of building…

Passive House Construction and Tapes

1024 768 The Turett Collaborative

Tapes have become an essential component in building today, especially with Passive House projects. Since Passive House standards require an airtight building envelope, not using tapes is not an option. Every Passive House project utilizes something called the ‘Air Barrier’ which uses one or many layers of sheathing and tapes on the structure to prevent inefficient air leaks. Tapes seal the air barrier and help to stop air leakage so that Passive House projects can stay airtight and energy efficient. It is essential to include a line item for tape in construction estimates for Passive House projects.  Many different types of tapes are used in the construction of the Greenport Passive House by Turett. Zip Tape to tape all seams of the Zip Sheathing, Aluminum faced tape to seal the polyisocyanurate insulation seams, Blueskin Butyl flashing tape in the window…

Estimating Passive House Construction Costs

700 1024 The Turett Collaborative

Passive House projects have slightly different materials used in the construction, therefore costs are not always the same as conventional housing projects. In the Greenport Passive House, the air barrier is achieved using Zip Sheathing and Zip tape. Exterior insulation of polyisocyanurate (4″ walls, 6″ roof) and 1″ wood furring is attached to the Zip Sheathing using long structural screws. This is unique to Passive House projects because the insulation used tends to be thicker than on a conventional house. In the end, over 5,000 screws were used to attach furring and insulation to the outside of the vapor barrier sheathing. The screws alone cost over $6,000. Installing insulation over the air barrier. Furring strips attached over the insulation. Over 5,000 screws were used in this project. Installing the cedar shiplap siding Shiplap cedar siding installation shot.

Greenport Passive House Update

768 1024 The Turett Collaborative

The Turett Collaborative is currently in the process of building a Passive House residence in Greenport, New York. Passive House buildings (also known in Europe as Passivhaus) adhere to design principles that prioritize energy efficiency in a building, reducing its ecological footprint. Passive House structures are very low energy buildings. They require little energy for space heating or cooling. Passive Houses employ continuous insulation throughout the entire building envelope. In the slideshow you can see how much insulation a Passive House Needs. The insulation on the Greenport Passive House will be over 4″ thick! The building envelope for a Passive House is as airtight as possible, preventing further loss of conditioned air. High-performance windows and doors further reduce heat or cooling losses. Solar positioning can be utilized for a Passive House’s heating needs during cooler seasons. By working with a…
