There is a great deal of innovation in the use of wood inconstruction, from impressive modern buildings to new constructionproducts that reduce build times and improve building performance.As a renewable resource with proven low embodied energy, wood isboth an environmentally responsible and a highly practical choiceas a construction material. However, forest managementpractices vary throughout the world: some are highly effective indelivering a sustainable, long term supply of timber; whereasothers are less so, and could result in forest depletion andsignificant environmental degradation. Against thisbackground, a number of certification schemes have been developedthat seek to ensure that all timber is harvested from sources thatare at least legally-sourced, and at best, sustainablymanaged.
Sustainable Use of Wood in Construction explains how andwhy wood may be grown sustainably, and how this versatile materialcan be specified and - most importantly - sourced, foruse in the construction industry. It explains the modern regulatoryframework within Europe that seeks to eliminate the use ofillegally-harvested wood, and it shows how to ensure that everyonewho sells or uses wood for construction is following the rules.Finally, the book explains how, at the end of its first use inconstruction, wood can be recycled, by reprocessing into anotherwood-based construction material, or by using it as biomass.
