The economic evaluation of installing renewable energy system into public buildings in Sinseo Innovation City, Daegu
According to an increasing demand of political support and development on renewable energy as a solution for the energy problem in Korea, the government has established a goal to raise renewable energy supply from 2.27％ to 5％ until 2011. Especially in the case of public building in which energy use is in great demand, it would bring the great advantages to develop and utilize the photovoltaic system as sources of electric power energy and geothermal heat pump system as sources of thermal energy. On the occasion of the photovoltaic system, solar module can be used as an architectural material so that it can reduce construction cost and it is possible to make buildings own power supply. As for geothermal heat pump system, it can be used infinitely as long as the solar energy exists and operation cost is cheap and yearly efficiency is stable. However, we need to make a plan to reduce early investment expanses of these two systems and to expand a diffusion rate as we develop a competitive domestic technology level. So in this study, we are going to perform evaluation of economical efficiency according to installing the photovoltaic systems and the geothermal heat pump systems in the public buildings which will be built up in Sinseo innovation city, Daegu. As a first step, we will investigate present installation condition of these two systems and based upon that, will seek efficient introduction program of renewable energy systems that can be applied in the public buildings.
