The world has recognized the shortage of energy resources. New and renewable energy development is the focus of much research and investment, and the world is trying to reduce carbon emissions. In November 2009, the Korean government announce a greenhouse gas emission reduction target of 30% by 2020. In this study, an underground heat exchanger was installed on the underside of the smart deep tunnel. The heat energy was calculated using the TOE conversion table from the Korea energy management corporation. Moreover, It is proposed to install heat exchanger in smart deep tunnel through reduction of carbon dioxide emissions and analyzing economic effects of carbon dioxide emissions reductions.

As cases of unexpected environment catastrophes drastically increased because average temperature of Earth is increased by accumulated greenhouse gases in atmosphere due to the excessive use of fossil energy, it is necessary to decrease the greenhouse gas emission in urban planning aspect. However, current researches on urban planning and design method for carbon neutrality in national level is still in early stage. This study suggested absorption method for unavoidable outbreak of carbon dioxide by deducting planning factors and estimate of absorption according to the CO2 absorption objective.

These days it still writes on maintenance list by paper regarding safety inspection of bridge structures or saves data to be computerized. However this system occurs many problems regarding less data reliability, inefficiency system and subjective evaluation in bridge structures. This paper suggests smart bridge maintenance using NFC which is objective and high precision and tries to study that any body who takes a simple training can use this system simplified.

산업의 발전과 소득의 증대는 국민들의 삶의 질 향상을 한층 더 요구하게 되어 보다 안전한 생활을 영위하고자 하는 욕구가 증대되고 있으며, 지난 2011년 3월 일본의 쓰나미 사건 이후 재해에 대한 많은 관심을 가지게 되었다. 뿐만 아니라 기후 환경의 급속한 변화로 환경을 보호하고자 하는 노력들이 계속되고 있으며 국내에서도 지난 2008년 국가비전으로 제시된 청정에너지와 녹색기술을 통해 에너지자립을 이루겠다는 녹색성장 기본법이 발효됨으로 각 분야에서의 친환경에 관한 필요가 증대되고 있다. 터널은 그 특성상 터널 내 재난 발생 시 효과적인 초기대응이 어렵고 인명피해 발생이 불가피하며, 오염물질의 제거가 어렵다. 따라서 터널이용자들이 재난발생시 용이하고 신속하게 대응할 수 있는 방재 시스템과 효과적이고 친환경적인 환경조성, 환기계획은 매우 중요한 요소이다. 본 논문에서는 기존터널에 부재되었던 친환경적인 요소를 부합한 신개념 Organic Green Tunnel 시스템을 제시하고자 한다.
