Korean government decided to give a subsidy for renewable energy system of green home. This policy will make an appeal to consumers. But For success of this policy, Economic benefit of consumer is essential. In this study, benefit and cost is seperated to consumer part and government part, respectively. consumer's benefit is energy saving and asset value increment. Consumer's cost is real input money except government's subsidy. Government's benefit is consist of energy import reduction, carbon discharge reduction and new production increment, As a result, the government subsidy will not so enough to activate the green home. PV system for the korean general apartment has the payback period of 19 years. So, For the dissemination of renewable energy of green home, more strong subsidy policy and more economic technoloy development is requested.

그룹홈에 거주하는 청소년들의 그룹홈 체험의 의미를 탐색하였다. 연구참여자들은 가족유대의 신화가 깨어진 경험을 통해 그룹홈 입소를 하였다. 그룹홈에서 또래들과의 다양한 상호작용을 통해서 자신들의 삶의 경험에 대해 새로운 해석을 하고 있다. 본 연구를 통해 그룹홈 청소년의 체험은 부대낌을 통해 정을 다지고 신뢰하게 되며 '보살핌'을 통해서 성장하는 과정에서 타인을 식구로 선택하며 버거운 '자립'의 과제를 풀려고 고심하고 있음이 드러났다. 연구의 결과로 그룹홈에 관련된 정책 및 실천이 그룹홈 거주 주체인 청소년들의 성장을 원조할 수 있도록 기초 자료를 제공하였다.

In respond to the global energy crisis and climate change, there have been many ongoing national efforts to develop a sustainable housing prototype followed by "2 million Green Home Project" in Korea. More than 50% of nation's population are currently living in apartment housing thus the country is seriously in need of developing green apartment prototype. In this research, we focused on energy-conservative green apartment design prototype that have both passive components and active systems explored in a systemic design approach. After selecting an existing basic apartment unit, we analyzed and compared statistical data with the simulated annual energy consumption to match these two data sets for validating simulation accuracy performed with TRNSYS package. We performed energy simulations with different passive design factors such as varied insulation thickness, window types and infiltration rates as well as the active design factors including boilers and lighting fixtures to analyze their impacts on the energy performance of the housing unit using TRNSYS software. As a result, we acquired significant energy reduction effect with explored design strategies but the life cycle cost analysis for the final design guidline would need to be performed. In this study, we focused on a systematic comparative energy analysis based on TRNSYS that can improve the design of a green apartment housing.
