The History of Superinsulated Houses in North America

Slides from a PowerPoint presentation

Posted on Oct 10 2010 by Martin Holladay

Several readers have requested a copy of a presentation on “The History of Superinsulated Houses in North America.” I have made this presentation at three conferences:

  • at the Fourth Annual North American Passive HouseA residential building construction standard requiring very low levels of air leakage, very high levels of insulation, and windows with a very low U-factor. Developed in the early 1990s by Bo Adamson and Wolfgang Feist, the standard is now promoted by the Passivhaus Institut in Darmstadt, Germany. To meet the standard, a home must have an infiltration rate no greater than 0.60 AC/H @ 50 pascals, a maximum annual heating energy use of 15 kWh per square meter (4,755 Btu per square foot), a maximum annual cooling energy use of 15 kWh per square meter (1.39 kWh per square foot), and maximum source energy use for all purposes of 120 kWh per square meter (11.1 kWh per square foot). The standard recommends, but does not require, a maximum design heating load of 10 W per square meter and windows with a maximum U-factor of 0.14. The Passivhaus standard was developed for buildings in central and northern Europe; efforts are underway to clarify the best techniques to achieve the standard for buildings in hot climates. Conference in Urbana, Illinois (October 16, 2009);
  • at the 14th Annual Westford Symposium on Building Science (August 3, 2010); and
  • at the annual meeting of the British Columbia Building EnvelopeExterior components of a house that provide protection from colder (and warmer) outdoor temperatures and precipitation; includes the house foundation, framed exterior walls, roof or ceiling, and insulation, and air sealing materials. Council in Vancouver (September 22, 2010).

  1. The Superinsulated Retrofit Book

I thought you would get a kick out of this . . .

I recently went to the main branch of my county library. Although they had over a dozen books on passive solar design, a lengthy catalog search for "superinsulation" resulted in ZERO entries.

So I had to use the interlibrary loan process to order "The Superinsulated Home Book," by Nisson and Dutt. The lady at the help desk, although very competent, spent quite a bit of time trying to find the closest copy. It was in a university library, several hours away!

The library trip left me questioning how passive solar triumphed in terms of exposure and press, while superinsulation withered? Was the debate resolved too late? Was it because it happened at the end of the economic recession, or at the beginning of Reaganomics? ;-)


Anyway, thanks for dispelling some of the myths and misinformation out there!

I'm glad you were able to find The Superinsulated House Book through inter-library loan. (I noticed that the price of used copies is rising -- Amazon is now advertising used copies for $48.)

Among those following the solar versus superinsulation debate, I believe that the debate was resolved in favor of superinsulation by the early 1980s. But those interested in the topic were always a small minority of U.S. builders.

Through the late 1980s and the 1990s, the torch of superinsulation was carried by members of EEBA (originally the Energy Efficient Builders Association, now the Energy and Environmental Building Association) and by subscribers to Energy Design Update. In Europe, the torch was picked up by Dr. Wolfgang Feist and his Passivhaus builders.

Among those who cared, the necessary specifications for a superinsulated house were well known. The only problem was, few people cared.

Do you have contact information for Brian Marshall and Robert Argue?

Sorry, I don't. You might check with some Canadian experts like Harold Orr or Rob Dumont -- perhaps they can help you.

Robert Argue Info

Hi Martin,

A couple of years ago, I met Robert Argue. At the time, he lived near Perth Ontario and was working for an environmental protection organization called ecoPerth.
