Today, various activities to save energy are being conducted around the world. Even in our country, carbon reduction policy is being conducted for low carbon green growth and with this movement, effort to replace energy sources by recognizing the problems on environment pollution and resource exhaustion due to the indiscrete usage of fossil fuel is being made. Therefore, active study on renewable energy is in progress as part of effort to replace the energy supply through fossil fuel and solar ray industry has rapidly developed receiving big strength of renewable energy policies. The conclusion of this study measuring the surface temperature change of single crystal and polycrystalline PV module in green roof system and non-green roof system aspect are as follows. There was approximately $4^{\circ}C$ difference in PV module temperature in green roof system and non-green roof system aspect and this has the characteristic to decrease 0.5% when the temperature rises by $1^{\circ}C$ when the front side of the module is $20^{\circ}C$ higher than the surrounding air temperature following the characteristic of solar cells. It can be concluded that PV efficiency will be come better when it is $4^{\circ}C$ lower. Also, in result of temperature measurement of the module back side, there was $5^{\circ}C$ difference of PV module installed on the PV module back side and green roof system side on the 5th, $3^{\circ}C$ on the 4th, $2^{\circ}C$ on the 5th to show decreasing temperature difference as the air temperature dropped, but is judged that there will be higher temperature difference due to the evapotranspiration latent heat effect of green roof system floor side as the temperature rises. Based on this data, it is intended to be used as basic reference to maximize efficiency by applying green roof system and PV system when building non-green roof system flat roof.

인간 활동에 의해 증가된 온실가스로 인하여 지구촌 곳곳에서 기상이변이 속출하고 있으며, 세계적으로 온실가스 배출 감축을 위한 노력을 하고 있다. 여기에 발맞추어 우리나라 또한 녹색성장을 기조로 한 저탄소 사회 실현을 위한 노력을 하고 있으며, 이를 위해서는 녹색생활을 통한 저탄소 소비 패턴 정착이 필요하다. 이에 국민들에게 저탄소 생활로의 변화를 통해 저감되는 온실가스 배출량 정보 제공이 요구되는 바, 본 연구에서는 국내에서 소비되는 식품들 중 수입의 비중이 높은 쇠고기와 포도주를 대상으로 하여 국내외산 쇠고기와 포도주의 푸드 마일리지 및 이산화탄소 배출량을 산정하였고, 수입산과 국내산의 이산화탄소 배출량 산정 결과를 이용하여 수입산을 국내산으로 대체할 경우에 저감 가능한 이산화탄소 배출량을 평가하였다. '07년 기준으로 수입 쇠고기 10%를 국내산으로 대체하면 연간 14,000톤 만큼의 이산화탄소 감축이 가능하며, 일 년 중 하루를 수입 쇠고기 대신 국내산으로 대체했을 때에는 연간 384톤 만큼 감축이 가능한 것으로 나타났다. 같은 방법으로 수입 포도주 10%를 국내산으로 대체하면 연간 1,396톤이 감축되고, 일 년 중 하루를 수입 포도주 대신 국내산으로 대체했을 때에는 연간 38톤의 감축이 가능한 것으로 나타났다. 푸드 마일리지와 같은 정량적 지표를 사용하여 국내산 식품의 수요를 유도함으로써 국민들의 실생활 속에서 자연스럽게 저탄소 생활로의 소비 패턴이 이루어질 수 있을 것이며, 앞으로도 이러한 정량적인 이산화탄소 배출량 DB의 개발과 보급이 필요할 것으로 사료된다.

Recently, Korea parliament legislated the Low Carbon Green Growth Act (April, 2012) and approved a bill (May, 2012) to start carbon emission trading system in 2015. It means that for the first time, government would regulate the amounts of carbon emission in private entities, and private entities should attain predefined emission reduction goals by implementing clean development mechanism (CDM) project or buy the Certified Emission Reductions (CERs) from the trading market to avoid penalty. Under these circumstances, it is not easy for them to determine when or how to implement the CDM project because the governmental energy policies about the level of governmental subsidies, periods for free emission allocation, etc. are still under discussion and the future price of the CERs is quite uncertain. Thus, this study presents a real-option based model to assess the financial viability of the CDM project which switches bunker-C oil to liquefied natural gas (LNG). The proposed model is expected to assist private entities in establishing the investment strategy for CDM project under uncertain government energy policies.
