Since korea must get 5.2% reduction of green gas emission and insecurity of economic impact is on the increase due to unstable oil market, the demands of energy saving techniques are increasing. In this paper, we investigate necessity of development of enormous energy used cleanroom energy saving techniques furthermore we also investigate the adoption of dependability management system to develop the energy saving cleanroom development process.

  This study is provide information in the development of energy conservation technologies by means of technological demand survey covering energy market and industrial field among energy-related technologies.   For this purpose, we check both the present

This study is to provide information in the development of energy conservation technologies by means of technological demand survey covering energy market and industrial field among energy-related technologies. For this purpose, we check both the present state of energy technologies and trends of social change in Korea, and then combine social needs with major, bottleneck, and essential technologies required for the future. The range of this study covers the field of industry, kiln, furnace, metal, building, transport, and electricity. For case study, valid 120 companies among the 500 companies selected randomly in the energy data-base of Korea institute of energy research (KIER) are considered.

Diffusions of energy conservation technology are very important class in our country that resources and energy are lacking, and development, transfer, diffusions etc.. of energy conservation technology can speak as one method that can improve country competitive power along with company competitive power. But, in the case of our country, present condition grasping about energy conservation technology passing․induction did not consist. This research grasp present condition about energy conservation technology passing․induction of our country and present direction for energy conservation technology activation, for which connected company into question investigation enforce and behaved frequency analysis and crossing analysis etc.
