The building sector contributes about 25.2% on greenhouse gas emissions in our country. Especially, this building sector would be more important in terms of emission amount and reduction potentials based on the expert`s opinions. The purpose of this study is to make the benchmark(BM) indicator of greenhouse gas of several types of buildings. Benchmark indicator could be important baseline for allocation of carbon reduction, and helpful for policy makers in central and regional governmental agencies. For this study, the basic data is from the National Building Energy Management System, which integrated the energy data(electricity, gas, steam etc) and building data of all buildings in our country. We`ve considered the types of building and construction year to make a unit for BM. The regional scope is limited on Seoul city, because of data handling problem. As a result of this study, we`ve developed the 36 types of BM on Seoul city, and try to calculate the reduction potentials on GangNam-Gu and GwanAk-Gu in efficient way.

본 연구에서는 지표이용도 특성이 반영된 고해상도 기상예측모델 도시캐노피모형(WRF-UCM)의 수치모의 실험을 통해 도심과 전원 지역 기상변수 및 에너지수지 변화 경향에 대하여 분석하였다. UCM을 적용하지 않은 WRF 모의 결과를 규준실험으로 설정하였으며, 거칠기 길이 변화와 인공열 고려에 따라 총 4가지 실험을 비교하여 분석하였다. UCM을 적용한 실험에서 거칠기 길이의 수정 전과 후의 기온과 풍속의 변화가 크게 나타나지 않았으나, 인공열을 고려한 UCM의 모의 기온과 풍속은 고려하기 전보다 크게 차이가 나타났다. 모의 실험 간의 차이는 전원 지역보다 도시지역에서 더 크게 나타났다. 자동기상관측(AWS) 기온 관측 자료에 대하여 UCM에 인공열을 고려한 결과의 평방근오차(RMSE)가 가장 적었다. 또한, 차세대도 시농림융합기상사업단의 중랑 에너지수지관측소지점의 현열플럭스 관측자료에 대한 검증 수치는 인공열을 고려하여 UCM을 적용한 실험의 RMSE와 BIAS 값이 가장 낮았다. 인공열을 고려한 UCM 적용이 도심의 현열플럭스 모의 향상에 영향을 주었다. 또한, UCM을 적용한 후 도시 지역 잠열플럭스의 변화 모의를 분석할 수 있었으며, 도심과 전원 지역 모두 UCM 적용후에 관측 값과 더 가까운 검증 수치를 나타냈다. 결과적으로 WRF 모델에 UCM의 적용이 지표플럭스 모의 향상에 기여하는 것으로 나타났다. In this study, the high-resolution numerical simulation results considering landuse characteristics are analyzed by using single layer Urban Canopy Model (UCM) in Weather Research Forecast (WRF). For this, the impact of urban parameters such as roughness length and anthropogenic heat in UCM is analyzed. These values are adjusted to Seoul metropolitan area in Korea. The results of assessment are verified against observation from surface and flux tower. Forecast system equipped with UCM shows an overall improvement in the simulations of meteorological parameters, especially temperature at 2 m, surface sensible and latent heat flux. Major contribution of UCM is appreciably found in urban area rather than non-urban. The non-urban area is indirectly affected. In simulated latent heat flux, applying UCM is possible to simulate the change similarly with observations on urban area. Anthropogenic heat employed in UCM shows the most realistic results in terms of temperature and surface heat flux, indicating thermodynamic treatment of UCM could enhance the skills of high resolution forecast model in urban and non-urban area.

This paper investigates financial risk tolerance of potential individual investor. It is easy to secure a sufficient sample number of potential investors and to identify efficient and appropriate investment risk tolerence for potential financial consumers, and analyze the correlation between investment experience and investment intention. Empirical results are as follows. First, there is difference between their own financial risk tolerance perceived by potential investors and financial institutions. Second, the potential investor's asset management experience have a positive (+) effect on the profit-driven tendency among financial risk tolerance, but negative (-) on the safe investment tendency or the aggressive investment tendency. Third, the experience of collecting investment-related information and the indirect investment experience has a negative (-) effect on the profit-driven tendency, while it has a positive (+) effect on the safe investment tendency and the aggressive investment tendency. Fourth, it was confirmed that most of potential individual investors have a risk-neutral tendency, as they had a positive (+) effect on the investment intention in financial assets such as stocks.
