Outline of Final Research Achievements	Compatible of the energy saving effect and the economic effect were simulated by using Input-Output Analysis in case of the room air-conditioning which belonged to a main home electronics. It is assumed that the energy consumption in case of using the existence model and replacing it with the excellent model the energy conservation performance becomes equivalent in the energy consumption of the whole life cycle.The power consumption, price and market life cycle (MLC) of the room air-conditioning were employed as parameters. The necessary energy saving performance was calculated based on 20,000 yen to 20,000 yen basis and on one year to one year basis of a market life cycle of the air conditioner. As a result, the product of high-price and environmentally-friendly had a lot of energy saving effects compared with the product of low-price and high environmental load.
