R-value (insulation) as ASHRAE 90.1 and the IECC prescribe U-values. However, R-value is widely used in practice to describe the thermal resistance of insulation products, layers, and most other parts of the building enclosure (walls, floors, roofs). Other areas of the world more commonly use U-value/U-factor for elements of the entire building enclosure including windows, doors, walls, roof, and ground slabs. The SI (metric) unit of R-value is whereas the I-P (inch-pound) unit is For R-values there is no difference between US customary units and imperial units, so the same I-P unit is used in both. Some sources use ″RSI″ when referring
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
