We aim to realize "Vision 2050: Japan Shines, Forest Circular Economy" promoted by the Platinum Forest Industry Initiative. We will disseminate ideas and initiatives to promote biomass chemistry, realize woody and lumbery communities, and encourage innovation in the forestry industry in order to fully utilize forest resources to decarbonize the economy, strengthen economic security, and create local communities.
In recent years, against the backdrop of efforts to achieve a decarbonized society, the expansion of ESG investing, and growing interest in well-being, interest in wooden offices and commercial facilities has been rapidly increasing. At the same time, information on leading examples, technologies, and policies regarding the actual progress of wooden construction in non-residential buildings is scattered across various media, making it difficult to gain a systematic understanding of the field.
In this 23-page document, the “Platinum Forest Industry Initiative—Wooden City Subcommittee” of the Platinum Vision Network (a general incorporated association) has compiled four leading case studies of wooden office and commercial buildings, along with the concepts, technologies, and institutional trends related to wooden cities. Please use this document as a resource for planning and proposing timber-frame construction projects, gathering information, and staying abreast of the latest trends in non-residential timber-frame construction.
We have systematically organized information that is useful for practical work in wood-frame construction.
・Leading Examples of Wooden Office and Commercial Buildings
・Technologies and construction methods used in wood-frame construction
・The Concept and Future Vision of a Wooden City
・Overview of Programs and Subsidies to Promote Wooden Construction
・Latest Trends in Wooden Construction
We will highlight cutting-edge projects involving wooden office and commercial buildings, introducing their distinctive features, the technologies used, and key evaluation points.
