In recent years, CLT (Cross Laminated Timber) has attracted attention as domestic forestry revitalization and reduction of LCCO2 of buildings are required. Hokkaido Larch accounts for 30% of the planted forests in Hokkaido. For that reason, CLT buildings using Hokkaido Larch are important for the utilization of forest resources and reduction of LCCO2 in Hokkaido. In this report, we report on the result of examining the thermal performance which has a big influence on energy reduction during operation.
