Abstract:

Throughout history, wood as a building material has been used extensively thousands years ago. It is considered the second known building material after stone; thus, it is recognized as an ancient building resource material. However, wood as a natural rigid material of plant origin has been substituted and associated with man-made common rigid materials in the building construction such as steel and concrete that are characterized with higher carbon emissions and lower sustainability. But with the rise of environmental stewardship in response to the high carbon emissions in cities, sustainable material usage in buildings has reached spotlights. Wood or timber is recently revitalized in contemporary construction as a sustainable built material for being highly renewable and nontoxic and having low embodied energy feature, even though it has been recently used in skyscrapers. In addition, stakeholders are encouraged to integrate timber in all various building types and to reinvest the sustainable material in construction for its recognized insulation, durability, flexibility, affordability, and aesthetic nature, not to ignore the benefits of wood to the building occupants in enhancing their emotional and physical connection with their occupied spaces. This work is intended to compose a significant achievement in educating architects to look at subjects normally ignored and to consider the use of organic material such as wood (timber) in meaningful ways. It focuses on enriching the knowledge base of sustainable wood and lumber in new and existing buildings by highlighting the advantages and disadvantages of timber material usage; it also aims at encouraging the sustainable experience of timber and broadens its usability and functionality in the industry. In this book chapter, local and global existing building cases are reviewed and assessed for the integration of timber as a construction material in the structure, skeleton, interior, and façade of these buildings. The advances and drawbacks of timber usage in construction are highlighted through the assessment of cases. Finally, a comparative analysis that emphasizes the sustainability of timber as a building material in different case studies is provided. Further, life cycle analysis of timber usage in buildings is to be studied.
