In this application, however, the decision was driven by the ease of installation- and the experience of the Mill Creek Net zero home. I used this discussion as a basis for our choice: http://greenedmonton.ca/mcnzh-foundation-wallsShafraazhttps://www.blogger.com/profile/12680723864772294621noreply@blogger.comtag:blogger.com,1999:blog-4533703094188189176.post-42429785755595044882010-12-02T12:55:27.868-07:002010-12-02T12:55:27.868-07:00The Oak Ridges National Laboratory, in the U.S., a...The Oak Ridges National Laboratory, in the U.S., assessed the most beneficial location for insulation in a concrete wall. They concluded that all the insulation should be placed on the exterior. It keeps the thermal mass of the wall warmer.

The conclusion was that placing all of the insulation on the exterior kept the thermal mass of the concrete warmer and drier.
