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
Good Building Design and Construction in the Philippines the weight of the structure. It must be composed of bedrock and must not be landfilled and is away from slopes and river beds. Broken rough rocks and fine sand must be used and must be free from external sediments as it may affect the strength of the concrete mix. Good Building Design and Construction in the Philippines The Good Building Design and Construction in the Philippines is a handbook developed in cooperation with the German Technical Cooperation (GTZ), UNDP Regional Center in Bangkok, and the Secretariat of the United Nations International Strategy for Disaster Reduction.
