The use of timber construction products and their environmental impacts is growing in Europe. This paper examines the LCA approach adopted in the European CEN/TC350 standards, which are expected to improve the comparability and availability of Environmental Product Declarations (EPDs). The embodied energy and carbon (EE and EC) of timber products is discussed quantitatively, with a case study of the Forte building illustrating the significance of End-of-Life (EoL) impacts. The relative importance of timber in the context of all construction materials is analysed using a new LCA tool, Butterfly. The tool calculates EE and EC at each life cycle stage, and results show that timber products are likely to account for the bulk of the EoL impacts for a typical UK domestic building.
Some innovative and structurally efficient uses of massive wood panels, such as cross-laminated timber (CLT), will result in hollow structural sections. Light-weight wood construction as well as heavy timber assemblies using dropped ceilings or raised fl...
The U.S. edition of the CLT Handbook is a 572-page guide and is the definitive handbook on cross-laminated timber (CLT), covering manufacturing, structural design, connections, fire and environmental performance and the lifting and handling of CLT elements.
