WOODRISE is sponsored by the International Association for Building and Housing Industry, and is an international event once every two years that brings together industry stakeholders for the development of middle- and high-rise wooden buildings. Events such as conferences and exhibitions “WOODRISE 2021 KYOTO” were held in Kyoto from October 15th to 17th last year, but due to the spread of the new coronavirus infection, programs such as B to B meetings could not be held this time.

In the lecture, it is necessary for the entire industry to make efforts to achieve the national goal of “increasing the amount of domestic timber used for construction materials, etc. by 8 million m³ compared to 2019 (* 1) by 2030”. Regarding construction costs, he stated that it is important not only to make efforts to reduce costs for businesses, but also to create economic value for wooden buildings, such as subsidy systems and CO2 emission rights transactions.

As a specific example, Obayashi Corporation’s high-rise pure wooden fireproof building “Port Plus® Obayashi Yokohama Training Institute” was built in Yokohama City, and at the same time it realized a carbon offset equivalent to 3,350 tons (* 2) and at the same time subsidized (* 3). ) And raised funds with ESG bonds, and contributed to the improvement of economic value and corporate value.
