R-value (insulation) typical straw bale houses have very thick walls and thus are well insulated. Snow is roughly R-1 per inch. Brick has a very poor insulating ability at a mere R-0.2 per inch; however it does have a relatively good thermal mass. Note that the above examples all use the U.S. (non-SI) definition for R-value. When determining the overall thermal resistance of a building assembly such as a wall or roof, the insulating effect of the surface air film is added to the thermal resistance of the other materials. In practice the above surface values are used for floors, ceilings, and
Construction Research and Innovation Strategy Panel funding with sectors such as aerospace and pharmaceuticals. The Design Task Group's report was turned into a book chapter by the group's chair, Giles Oliver. After chairing the Task Group on Value, Richard Saxon went on to publish "Be Valuable" through the industry body Constructing Excellence, while the Task Group report was used as the source of an academic paper. The Pearce Report "The Social and Economic Value of Construction" (2003) was used for a special issue of the journal "Building Research & Information", edited by Jim Meikle.
