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
Royal Commission into the Building and Construction Industry of the Australian Building and Construction Commissioner (ABCC). The role of the ABCC was to monitor and promote appropriate standards of conduct throughout the building and construction industry. The ABCC operated between 2005 and 2012. The Commission's own estimate of its expenditures, as at the date of publishing its report, was that it had spent approximately 60 million. This figure makes this Royal Commission one of the most expensive in Australia's history.
