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 regulate the conduct of industrial relations on construction projects funded by government, through the medium of contract rather than legislation. In July 1997 the (then) Department of Employment, Workplace Relations and Small Business formed a 'Workplace Reform Group' targeting four industries for reform: the meat processing industry, the coal mining industry, the building and construction industry and the waterfront industry. The Workplace Relations Act and the Trade Practices Act 1974 were to provide the legal tools to deliver reform. The 1998 waterfront dispute was a reflection of the focus placed on these important industries. At about the time that the
