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...

description 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 have considerable potential as sustainable materials over other alternatives such as steel and concrete. The aim of this investigation was to compare the environment impact, energy consumption, and life cycle cost (LCC) of diferent wood-based materials in identical single-story residential buildings. The materials compared are laminated veneer lumber (LVL) and glued laminated timber (GLT).
