Basic sector classification and regional input output tables were applied to analyze investments in construction and operation of an energy conserving office building (3 776 m^2) and a conventional office building, in order to obtain influences upon various industrial sectors and final consumption of raw materials. Consumption of raw materials for construction of an energy conserving building is same as that of a conventional office building, however the final demand for secondary product sectors is larger. Investment in energy sectors due to operation of the energy conserving building is 33 % compared with the conventional office building and the final consumption of raw materials, 45 % , because of influences due to investment in service sectors for building maintenance. Regional input output tables estimate the influences upon various industrial sectors in various areas. Assuming that construction site is Kanto, Chubu or Kinki area, 60-70 % of the final demand due to the construction is supplied in the construction site, however Hokkaido, Shikoku or Okinawa, between 30 and 50 %. The energy conserving building which is provided with higher technology facilities tends to concentrate the final demand in Kanto area, especially concerning sectors of metal and electrical products.
