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
Office of the Australian Building and Construction Commissioner Office of the Australian Building and Construction Commissioner The Office of the Australian Building and Construction Commissioner (ABCC) (2005–2012) was an independent, statutory authority, responsible for monitoring and promoting workplace relations in the Australian building and construction industry. The ABCC provided education, investigated workplace complaints and enforced compliance with national workplace laws in the industry. The ABCC did this by: The ABCC was abolished on 31 May 2012, and many of its functions were taken on by a new independent, specialist agency called Fair Work Building & Construction. The Royal Commission into the Building and Construction Industry was established in
