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 Australian Naval Reserve and conservation and arts organisations." The Commissioner was appointed to investigate certain matters in relation to the building and construction industry. Those matters were defined in the Letters Patent as follows: The powers of Royal Commissions in Australia are set out in the enabling legislation, the . Royal Commissions, appointed pursuant to the "Royal Commissions Act" or otherwise, have powers to issue a summons to a person to appear before the Commission at a hearing to give evidence or to produce documents specified in the summons; require witnesses to take an oath or give an affirmation; and
