Note: (a) the metal has already been considered for recycling. (b) From a life-cycle perspective, the renewability of the building material must be considered when calculating building material consumption and CO2 emissions. The building materials associated with renewability include reinforced steel, steel, architectural glass, aluminum extrusion, and wood. Although architectural glass and wood can be totally or partially recycled, recycled glass generally cannot be used again for construction. Wood also cannot be used directly in construction without further processing. Therefore, there is no need to consider the recycling and reuse of glass and wood. |
