1. Introduction The method of utilization of waste heat from ILC depends on the temperature and magnitude of waste heat from each sub-system of ILC. We have investigated heat supply service and the related engineering by studying various facilities whose conditions are similar with ILC in regional characteristics. Based on the investigation and its result, we propose: A heat energy management service, Supplying attractive environment to agriculture corporation, A preceding model of utilization of waste heat for facility agriculture. 2

3. Possibility of heat supply service (continued) 3.1 Agricultural complex Study of utilization of waste heat energy for agriculture based on interview with experts Since agricultural land area per farmer of Japan is very small, large scale facility agriculture using waste heat from ILC must be operated with a corporation. One possible business model is to complete the facility by the corporation and lease with full turn key contract. Government model project: Policy of the Japanese government is also facing the large scale facility agriculture (same as above). The unit area of the government model project is 4 ha. Consider agricultural production and sales together Fuel fee accounts for 30% of selling price Therefore, the stable and low cost heat energy is very efficient. 6
