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
Green building and wood SNS-activated state have a negative effect on the body’s physiological and psychological health. The study supports wood’s value as a tool in evidence-based design (EBD) – a growing field that seeks to promote health and other positive outcomes such as increased productivity and well-being based on scientifically credible evidence. So far, EBD has focused largely on healthcare and, in particular, patient recovery. Green building seeks to avoid wasting energy, water and materials during construction. Design and building professionals can reduce construction waste through design optimization, using right-sized framing members, for example, or pre-manufactured and engineered components. The wood industry reduces
