Cross laminated timber (CLT), which has higher performances in terms of heat storage and insulation, durability, and workability compared to standard wooden construction materials, is becoming familiar mainly in Europe and the US. The Japanese government has also made a cabinet decision to adopt a policy to establish a building design method using CLT made in Japan.
The practical use of CLT will lead to the development of the Tohoku region, where forestry is one of the prime industries. Accordingly, Panasonic jointly worked with the Fukushima Prefecture CLT Promotion Council and Shibaura Institute of Technology and measured the heat storage and insulation performances and electricity consumption during the use of air conditioners in the CLT experiment building. The energy-saving performance of CLT buildings was also evaluated, and it was verified that comfortable spaces can be created year-round through eco-conscious air-conditioning.
Based on these test results, the first CLT apartment housing in east Japan were completed in Yugawa Village, Fukushima Prefecture this February. A wide variety of Panasonic’s eco-conscious products, systems, and housing equipment were adopted, which enhances environmental efficiency and design aesthetics.
