Various environmental problems due to rapid industrialization and urbanization have worsened to such an extent that they threaten the environmental restitution of the globe and become a critical international issue. Korean government has presented the concept of green growth as a new state vision for the next 60 years and is making efforts to solve these environmental problems. Daegu Metropolitan City has faced various environmental problems including overpopulation of the city, traffic pollution, household waste accumulation and the green zone problem because of the increase of urbanization over the last few decades. As such urbanization continues, the quality of residential environments is rapidly deteriorating and the intensive use of the land leads to an increase of building area, raising the temperatures of cities. There have therefore been demands for healthy, pleasant and satisfying residential environments and for the improvement of existing residential environments, and this demand has been fully recognized by society. Nevertheless, current residential complex developments concentrate only on raising the efficiency of land use. In related laws of the past (Daegu Metropolitan City, Urban Planning Municipal Ordinance as of October 10, 2003) an attempt was made to impose a standard to segmentalize the building-to-land ratio, floor area ratio and regulations of number of floors vertically. However, these laws have now been abolished and the regulations are being eased. The purpose of this study was to analyze the characteristics of the floating wind before and after the vertical segmentation of residential areas (Daegu Metropolitan City, Urban Planning Municipal Ordinance as of October 10, 2003) by using KLAM_21, a model that enables analysis and prediction of the flow and generation of cold wind. The purpose is also to present a plan to improve the quality of residential areas when developing a building lot and redeveloping housing areas.

It is important to secure green spaces to solve the urban heat island phenomenon, which is among problems resulted by high-density developments in metropolitan areas. However, it is hard to secure such green spaces in established urban areas so Green Rooftop development approaches have recently been highlighted and introduced as a solution to the situation. The present study conducts a simulation on residential areas in urbanized regions to quantitatively evaluate the effects of green rooftop developments through a comparison of changes in the air temperatures before and after relevant development projects. According to the evaluation results, when the green roof top development is conducted in the available areas, the temperature is reduced by 0.14 degree. The extension of green project to the entire building showed the reduction of the temperature by 0.29 degree. Based on these results, it can be concluded that the green rooftop development is a practically solution for reducing the air temperature of urbanized areas.

김대욱(Kim, Dae-Wuk),김중권(Kim, Jung-Kwon),정응호(Jung, Eung-Ho) 한국도시설계학회 2010 도시설계 : 한국도시설계학회지 Vol.11 No.2

본 연구에서는 대구광역시 중구의 국채보상운동기념공원과 2.28기념중앙공원을 대상으로 도시공원의 조성 후 열섬 영향 정도와 미기후환경 변화를 정량적으로 분석하여 과거대비 미기후 측면의 효율성 검증과 도시내 공원의 중요성 및 필요성에 대해 살펴보고 이를 바탕으로 미기후개선을 위한 친환경적 도시공원 계획 및 도시계획 방안 제시를 목적으로 한다. 본 연구에서는 대구광역시 중구에 위치하는 2.28기념중앙공원과 국채보상운동기념공원을 대상으로 3차원 미기후분석프로그램인 ENVI-met을 이용하여 미기후환경(온도, 습도, 바람)의 변화를 분석ㆍ고찰하였다. 2.28공원 및 국채보상기념공원 조성으로 인한 미기후환경 변화를 요약하면, 지점별로 차이가 있지만 기존대비 각각 2.27%, 1.50%의 온도저감효과가 있는 것으로 나타났다. 습도는 기존대비 각각 5.52%, 2.83%의 상승효과가 나타났다. 본 연구는 과거의 미기후환경을 예측하여 공원 조성을 통한 미기후환경의 변화를 정량적으로 분석하였다는데 가장 큰 의의가 있다. 향후 도시계획 이전에 미기후의 변화를 모의하여 계획에 반영한다면 보다 쾌적한 도시조성에 효과를 줄 것이라 판단된다. This study examined the effect of Gukchae-bosang Memorial Park(GBM park) and 2.28 Jung-ang Memorial Park(JAM park) located at Jung-gu, Daegu on heat island phenomenon. The changes in micro-climate environment after the development of urban parks were analyzed quantitatively to evaluate the efficiency of the parks in terms of micro-climate control. The importance and necessity of urban parks are reviewed based on the analysis, and the guidelines for eco-friendly park and town planning are suggested. In this study, the microclimate environment factors of the urban parks, such as temperature, humidity, and wind, were analyzed and examined by ENVI-met -- a three dimensional micro-climate analysis program. The micro-climate environmental changes caused by the urban parks are as follows. The temperature decreasing effects by the parks were 2.27%(JAM park) and 1.50%(GBM park), and the humidity increasing effects were 5.52%(JAM park) and 2.83%(GBM park) respectively. The significance of this study is that the changes of micro-climate environment by urban parks were analyzed quantitatively on the assumption of the past micro-climate environment. It is expected that the simulation of micro-climate changes from the results of this study helps planners develop a better plan to create more pleasant urban environment.

오상학,김대욱,류지원,차재규,정응호,Oh, Sang-Hak,Kim, Dae-Wuk,Ryu, Ji-Won,Cha, Jae-Gyu,Jung, Eung-Ho 한국지리정보학회 2011 한국지리정보학회지 Vol.14 No.2

본 연구에서는 탄소배출 인벤토리 구축에 있어서 지리정보시스템을 활용하여 공간 특성에 따라 분포되고 있는 탄소 배출 규모를 살펴 보고자 하였다. 궁극적으로는 공간대응형 탄소배출 인벤토리를 구축함으로서 온실가스 저감형 도시 공간구조 조성을 위한 기본방향을 제시하고, 친환경적인 녹색 도시로의 변화에 기여하고자 하였다. 지리정보시스템에 입력되는 기초 Data 중 속성정보는 대구광역시 에너지 부문(전력, 도시가스)의 2009년 연간 사용량을 가지고 IPCC 가이드라인에서 제시하고 있는 Tier 1에 대입하여 $CO_2$ 배출량을 추정하였다. 공간정보는 대구광역시 건축물 대장과 지적도를 연계하여 지번에 따라 건축물 용도별로 토지이용 분류를 실시하여 구축하였다. 에너지 부문의 $CO_2$ 배출 인벤토리 구축에 지리정보시스템을 접목함으로서 공간별 $CO_2$ 배출 규모를 파악할 수 있었으며, 토지이용에 따라 $CO_2$ 배출 현황이 각기 상이한 특성을 가지고 있다는 것을 확인할 수 있었다. In this study, $CO_2$ emission quantities by spatial characteristics using GIS were investigated for building a $CO_2$ emission inventory. Eventually, this study provides the guidelines to build the urban spatial structure for reducing greenhouse gas and contributes to the transition to environmental friendly green city. The attribute data for GIS were energy (electricity and gas) usage in the city of Daegu for 2009 and used for Tier 1 as suggested by the IPCC guideline to estimate amount of $CO_2$ emission. The spatial data were built based on land use types categorized by building purposes with connecting building registers to cadastral maps for Daegu city. Spatial $CO_2$ emission quantities could be calculated by combining $CO_2$ emission inventory for energy and GIS. Also, $CO_2$ emission characteristics were different by land use types.

This study aims to improve the thermal comfort level of detached housing area by reducing the impact of thermal environment. The study focused on reducing surface temperature that is generated in buildings and adjacent spaces as a result of sensible heat load and presented a proposal on implementing planting method considering its outdoor condition and structure and composed materials. To perform the study, we utilized 3D-CAD to examine the outdoor condition and structure and composed materials that impact on surface temperature and conducted space design after reflecting climatic elements in simulations. The result is as follows. In reviewing temperature distribution of Heat Island Potential (HIP) of buildings and adjacent spaces, in case where green coverage ratio is increased, there was a $6^{\circ}C$ temperature difference and in regard to changes in the thermal environment in detached housing area, in case where rooftop planting, surface improvement, planting, and overall green coverage ratio is increased, there was a $10^{\circ}C$ temperature difference. In addition, there was difference in temperature in detached housing area following the changes in wind.

본 연구는 대구지역을 대상으로 공간적 지형특성에 따라 실제 바람생성에 영향을 미치는 공간지형적 요소별로 바람생성 기능을 평가하였다. 바람생성 기능에 영향을 미치는 공간지형적 요소가 매우 다양하고 상호영향관계에 있기 때문에 기본적으로 공간특성에 대한 정확한 기초자료의 확보가 매우 중요하다. 그러나 본 연구에서는 관련자료 취득의 어려움으로 인하여 신뢰성 있는 자료의 확보가 매우 제한적이었다. 이에 본 연구에서는 이에 대한 대안으로 위성영상자료의 활용을 시도하였으며, 그 결과는 다음과 같다. 먼저 대구지역의 공간지형적 특성상 바람생성 기능이 높은 지역이 많음을 확인할 수 있었다. 이들 지역은 대부분 시외곽지에 분포하고 있으며, 상대적으로 시가화된 지역에서는 바람생성기능이 극히 열악한 것으로 나타나 공간적 불균형이 매우 크다는 것을 확인할 수 있었다. 그리고 이들 지역이 시가화된 지역과의 공간적으로 연계되는 부분에서는 바람생성 기능이 매우 약화되고 영향범위가 축소됨을 알 수 있었다. 결국 시가화된 지역으로 유입되는 바람길의 효과가 감소되는 결과를 초래하고 있는 것으로 나타났다. 또한 본 연구를 통하여 바람길 생성 평가를 위한 공간자료의 구축수단으로 위성자료의 활용가능성을 확인할 수 있었다. This study has conducted the survey Daegu area on the evaluation of the wind generation by the spatial geograph conditions and according to the elements that practically affecting the generation of the wind. Because the elements affecting the wind generation are very diverse and interrelated, it is very important to secure accurate fundamental datas. For getting these datas, by applying satellite images to the study, more accurate datas were collected and the result of study is summarized as follows First of all, it has been acknowledged that due to the Daegu`s geographic features, there are a lot of areas with high wind generation, but most of these areas have been distributed in the outskirts of the city, where as in the areas wind generation is relatively very low in the urbanized areas, which indicate that the spatial unbalance is very high. And what is more of wind generation in certain areas where places spatially connected to the urbane district, show very low wind generations, and its influenced range become limited. From this fact, it can be estimated that the effects of the wind corridor coming into the urban district will be reduced. And also through this study, it could be verified that there are ample possibility of applying the satellite data as a means of building up the spatial data for evaluation of formation of the wind corridor.
