Asia is the largest regional construction market worldwide accounting for some 40% of global construction spending in 2012, and it is forecasted to account for almost one half of global construction spending by 2020. While mid- and high-rise buildings have been dominated by concrete and steel in Asia, climate change, urbanization, sustainable development and world housing needs have created a case for wood as a structural material in buildings. With governments seeking lower carbon building alternatives and renewable materials, there is a growing interest to use mid-rise and tall wood buildings in countries like China, Japan and South Korea.
This workshop will present market opportunities, government policy, research and development, and code and standard work to advance mid-rise and tall wood construction in China, Japan and South Korea.

Canadian Initiatives to Expand the Global Market for Sustainable Wooden Construction
Speaker: Shawn Lawlor
Established in 1974, the Canada Wood Japan Tokyo Office has a proud tradition of collaborating with local researchers, code officials, and industry to advance the use of wood in construction. In recent years, our focus has been to grow the market for wood use in mid-rise, non-residential, and mass-timber applications. This presentation will centre on two innovative R&D initiatives we are conducting to achieve these goals. The first case study will narrate the in-market technical development and promotional initiatives aimed at adapting and commercializing the high-performance Midply shear wall system. The second case study will detail current initiatives aimed at code recognition of NLT floor and roof applications. The presentation will provide timelines from the early stages of market and technical consultations through to code approvals and commercial adoption. The objective of this presentation is to share best practices on how to leverage promising research and multi-jurisdicational partnerships to effectively commercialize building technologies.
Practice of Wood Urbanization in Korea
Speaker : KiCheol Bae
Korea has a long tradition of wood culture and architecture, but is a bit of a latecomer to the contemporary mass-timber building industry. This presentation is about the current trends and future potential of wood construction in Korea. Examples of post-beam glulam structure for a research centre, cross-laminated timber (CLT) for a dormitory, and Ply-Lam CLT for a new type of housing are introduced and discussed. Finally, there will be a discussion on why we need “wood urbanization” and how we practice it in our urban environment.
Introduction of Technical Standard for Multi-Storey and High-Rise Timber Buildings and Application of Wood Construction in China
Speaker: Xuebing Yang
Although China has a long history of using wood in construction, buildings nowadays are primarily built using concrete and steel. While these two materials have proven to be exceptional structural choices and will continue to be important materials in the construction of buildings, climate change and sustainable development have created a case for wood as a structural material in buildings. In this presentation, wood structure–related standards in the Chinese engineering construction standard system will be introduced. The main technical contents of the Chinese national standard “Technical Standard for Multi-story and High Rise Timber Buildings” GB/T 51226 will be presented. In addition, the applications of timber structures in the Chinese construction market and future trends for using wood construction, in particular the multi-storey and high-rise timber structures, will be analyzed.
Chun Ni is a principal research scientist in Building Systems at FPInnovations. He received his bachelor and master degrees from Tongji University in 1985 and 1988, and a Ph.D. degree from University of New Brunswick in 1997. Since joining the organization in 1997, Dr. Ni has undertaken numerous research projects that involve extensive experimental and analytical study of the structural properties of wood members, joints and building systems. He has published more than 160 research papers and reports, and is a member of Canadian Code Committee CSA O86 – Engineering Design in Wood, and the Objective Based Codes for Wood Frame Constructions. He was involved in the amendment of the B.C. Building Code to allow 6-storey wood framed residential buildings and the development of APEGBC technical bulletin for 5- and 6-storey wood framed residential buildings. He also participated in the NEESWood Capstone 6-storey wood framed building shake table tests in Japan in 2009. Since 2000, he has been actively involved in various Chinese codes and standards committee work on wood products and wood building systems. Together with Chinese counterparts, he is one of the key players in developing design provisions for wood-frame construction in the Chinese timber design, construction and inspection codes.
Shawn Lawlor graduated from the University of Ottawa in 1990. Upon graduation, he worked for several years in Japan in education and public relations, subsequently returning to Canada to complete post-graduate studies under Capilano University’s Asia Pacific Management Program. Between 1995 and 2007, Mr. Lawlor pursued a career in Canada’s forest products industry, in progressively senior international marketing and sales management roles with Crestwood International Industries, Doman Western Forest Products, and Tembec Forest Products. In 2007, he joined the Canada Wood Tokyo Office as Managing Director. His key role is to lead a multi-disciplinary team to manage access and trade development initiatives on behalf of Canadian industry and government funding agencies. He has led numerous R&D, technical and promotional initiatives to expand wood use into Japanese mid-rise, large-scale non-residential and mass timber applications. Mr. Lawlor also spearheaded the Canada-Tohoku Reconstruction Project to rebuild wooden public structures in the Tohoku region affected by the 2011 Tsunami. He serves as Vice-Chair of the Osaka Lumber Cooperative Association and sits on a number of Japanese housing industry association committees, including the Japan 2×4 Home Builder Association and the Japan Wood Truss Association.
KiCheol Bae, KIA, LEED AP, is design principal of Innovative Design Studio, Inc. and also adjunct professor at Chung Nam National University in Korea. He has worked on several mass-timber projects in Korea and emphasizes ‘the necessity of urban wooden architecture’ to replace concrete apartments in modern cities, through lectures at WCTE 2016 Vienna and IWCC (International Woodism City Conference) 2017 Nagoya. Currently, he is focusing on studying prefabrication and wood. www.idsgrape.com
