In this study, Urban Climate Simulation was performed by 3-Dimensional Urban Canopy Model. The characteristics of urban climate was analyzed combining land coverage, building size, heat production from the air conditioning and topographic conditions as physical variables which affects urban climate characteristics. The results are as follows. (1)The aspects of the urban climatal change is derived to be related to the combination of the building coverage ratio, building height and shading area. (2)Whole heat generation was influenced by the convective sensible heat at the lower building height and by the artificial heat generation at the higher one over 20-story building influence to some extent of the building coverage ratio. The effect of the altitude is not more considerable than the other variables as below 1℃ of the air temperature. (3)When the water coverage 100% was made up, maximum temperature was declined by 5.5℃, wind velocity by 0.6m/s, convective sensible heat by 400W/㎡ and the evaporative latent heat was increased by 370 W/㎡ compared to when artificial coverage 100% was formed. These simulation results constructed as DB which shows urban quantitative thermal characters by the urban physical structure can be quantitative base for suggesting combinations of the building and urban planning features at the point of the desirable urban thermal environment.

In this study, Urban Climate Simulation was performed by :3-Dimensional Urban Canopy Model. The characteristics of urban climate were analyzed combining artificial land coverage, building size, heat production from the air conditioning and topographic conditions as physical variables which affects urban climate characteristics. The results are as follows. (1) The aspects of the urban clinmtal change is derived to be related to the combination of the building coverage ratio, building height and shading area. According to the building height, the highest temperature was increased by 2.1℃ from 2-story to 5-story building and the absolute humidity by 2.1g/㎏ maximum and the wind velocity by 1.0m/s was decreased from 2-story to 20-story building. (2) Whole heat generation was influenced by the convective sensible heat at the lower building height and by the artificial heat generation at the higher one over 20-story building influence to some extent of the building coverage ratio. The effect of the altitude is not more considerable than the other variables as below 1℃ of the air temperature. In the last, deriving the combination of building coverage and building height is needed to obtain effectiveness of the urban built environment planning at the point of the urban climate. These simulation results need to be constructed as DB which shows urban quantitative thermal characters by the urban physical structure. These can be quantitative base for suggesting combinations of the building and urban planning features at the point of thc desirable urban thermal environment as well as analyzing urban climate phenomenon.

This study aimed at framing alternative urban planning scenarios reflecting urban planning factors, performing urban climate simulation and evaluating eco-friendly and low energy characteristics of each scenario on the viewpoint of urban temperature and energy savings on the costal city including Haeundae District in Busan. The results are as follows. 1)The fact that urban higher temperature is approximately 2.5 times higher in the building constructed area than whole urban area was represented severe higher temperature phenomenon in the built-up area. While water scenario, ground greening, and soil scenario could be expected peek air temperature alleviating effect in order, air-conditioning temperature control scenario didn't affect alleviating urban higher temperature. Especially water scenario had significant effect(maximum 2.5℃) on lowering air temperature. 2)Building greening and water scenario were turned to be positive effect on urban air-conditioning energy savings but air-conditioning temperature control scenario showed linear increase of air-conditioning energy. This fact implies that building greening and water covered area constitutions had positive effect on urban energy savings but inducing air-conditioning load decrease through energy savings countermeasures can be an significant effect on energy savings. 3)Lower air temperature and energy savings characteristics could be classified with ①greening scenario for energy savings scenario, ②ground greening scenario, water scenario, and soil scenario for lower air temperature and energy savings scenario, and ③air-conditioning temperature setting scenario for energy increase scenario.

저탄소 녹색도시계획을 위한 환경·에너지계획정보 DB 구축방안

This study suggested the concept and the methodology of ‘E-GIS(Energy & Environment-Geographic Information System) DB‘ which is planning information on the side of urban planning and managing energy and environmental information systematically for realizing Low Carbon and Green Growth. A case study was executed on Residential Development District in Gwangmyeong and Siheung in Korea. The results are as follows. 1)E-GIS DB consists of 2 parts. E-GIS DB Part1 is integrated by urban environmental geographic information per each mesh unit including building complex planning information, land use planning and topology. E-GIS DB Part1 is input variable of urban climate simulation system. E-GIS DB Part2 is constructed by giving feedback of urban climate factors and cooling energy consumption drawn by urban climate calculation into E-GIS DB Part1. 2)Method of E-GIS DB construction this study suggested is on the target of the urban planning stage differently from existing city. Since building and land coverage planning is less fixed on the urban planning stage than the one of the existing city, building factors like use and sizes need to be extracted by approaching in the concept of ‘building complex’ in a urban block not a individual building and land cover information was obtainable by extracting natural land use like greenery or water areas from urban use plan regarding the situation after replacing original land cover with planned facilities. 3)From the case study, it was deduced that some adjustment is needed on building planning for the daytime high temperature and on land cover planning for the nighttime one, and that cooling energy use plan needs to be adjusted mainly on commercial area.
