Economic and environmental life cycle perspectives on two engineered wood products: comparison of LVL and GLT construction materials

The embodied carbon of building materials and the energy consumed during construction have a signifcant impact on the environmental credentials of buildings. The structural systems of a building present opportunities to reduce environmental emissions and energy. In this regard, mass timber materials...
