오피스 빌딩에 적용된 지열히트펌프 시스템의 경제성 평가에 관한 연구

Renewable energy has been getting popular as a natural energy source for green buildings these days. Public building with gross area more than 3000㎡, planned after March 2004, should spend about 5% of total building cost for equipment run by natural energy source according to renewable energy promotion law in Korea. Especially, geothermal heat pump system has been applied many buildings due to high efficiency and low energy cost. But research materials of efficiency measure and economic evaluation of geothermal heat pump system is insufficient. Therefore this research is a basic study for renewable energy resources and the date of this research will attribute to application of geothermal heat pump system in the future.
