Utilizing Local Wood for Economic Benefits in ILC Facilities Building
Explore the economic ripple effect of utilizing local wood in the construction of facilities for the International Linear Collider (ILC) experiment, highlighting the efforts by Shelter Co., Ltd., Iwate University, and the Iwate Prefectural Office in Japan. Discover the sustainable practices, urban forestry concepts, and the integration of wooden architecture in creating a green ILC city. Embrace the importance of locally produced wood, laminated timber production, and smart city initiatives for a more sustainable future.

The Shelter Corporation imagines a world of urban forests - cities formed of timber-framed buildings. In our architectural and urban planning, we study and research our environment and environmental issues. Shelter Co.,Ltd. Examples of Shelter s work: Town hall in Nan-yo city of Yamagata Prefecture 3

Green ILC city concept Green ILC EMS network Supply and demand Heat consumer Green ILC city concept is based on 6 points. Heat supply business adjustment ILC energy center Waste heat tank Chilled water tank Agriculture - The research facilities will be built based on international consensus that pursue sustainability. heat Heat supply Storage HASClay Storage Heat supply - Second, we aim to realize a smart city that is based Green ILC. Industrial park Chilled water Greenhouse - A network of heat users will be built. Hot water - Community facilities for ILC related researchers and engineers, are also based on wooden architecture. CHP Hot water ILC campus - A system to circulate local resources and funds by local companies. Chilled water CHP - We make smart city that can enrich whole area by establishing recycling-base society. http://www.illust-box.jp/db_img/sozai/00006/62464/thumb_20170103222525_586ba6458e80f.png Hospital and/or welfare facility Hot water Energy center Heat consumer area Information/commu -nication

Summary of economical ripple effect Direct expenses Wood (17.9 Billion yen) is 83.7% of Steel (21.4 Billion yen) Economical ripple effect Wood (2.2 Billion yen) is 167% of Steel (1.3 Billion yen) Employer-induced effect Wood (173 person) is 174 % of Steel (100 person) These are the results of following: Locally produced wood Laminated timber production by local companies Construction by local companies
Conclusions Wood + RC can have the same quality with Steel + RC such as strength, required construction period, and etc.. In addition, wooden building is friendly to people. Direct expenses of Wood +RC is 16.3 % cheaper than Steel + RC . The steel price is not stable in Japan, because of the large amount of steel frame will be required in near future in Iwate for the semiconductor companies. Local industries are the main player of this business. The policy of WOOD FIRST is very friendly for the local society because of the economical ripple effect and Increase of employment. Increase in timber demand is increasing the number of unused biomass, which is important for Green ILC strategy
We have been also working to make an urban design for ILC researchers, engineers and their families from all over the world. All houses will be made of local timbers by local companies. Thank you for your attention
