최근에 노후화된 도시정비사업으로 토지의 집약적 이용을 위해 아파트 및 공동주택을 초고층 및 고층 아파트 구조물로 재건축 승인함에 따라 인근 주거지역의 일조권 침해에 따른 사회문제로 대두되고 있다. 특히, 교육시설에 있어서의 일조량 침해에 따른 교육환경 여건은 많은 문제점을 내포하고 있다. 따라서, 본 연구에서는 이러한 교육환경 일조량 분석을 위해 Auto $CAD^{(R)}$ 프로그램을 이용하여 교육시설물에 대하여 3차원 모델링으로 구성하였다. 그리고, 시뮬레이션 기법으로 교육시설에 있어서 창과 운동장을 채광기준면으로 설정하여 태양의 움직임에 따른 진태양시의 일조량을 아침 8:00에서 오후 4:00까지1분 단위로 계산하였다. 또한, 아파트 신축공사 전 후의 피해에 따른 교육시설의 일조환경을 수치화하였고 일영투사법에 의해 제작된 영상과 비교하여 교육환경 일조량을 검증할 수 있었다. 향후 이러한 시뮬레이션 기법을 활용하여 교육환경일조량 분석에 효율적으로 사용될 수 있을 것으로 기대된다.

In this study, the observational environment for sunshine duration at Seoul and Daegu Automated Synoptic Observing Systems (ASOSs) was analyzed using a numerical model. In order to analyze the effects of topography and buildings on observational environment for sunshine duration, the model domains including the elevated building and mountainous areas around Seoul and Daegu ASOSs were considered. Three dimensional topography and buildings used as input data for the numerical model were constructed using a geographic information system (GIS) data. Solar azimuth and altitude angles calculated for the analysis period (one-week for each season in 2008) in this study were validated against those by Korea Astronomy and Space Science Institute (KASI). The starting and ending times of sunshine duration observed at ASOSs largely differed from the respective sunrise and sunset times simply calculated using solar angles and information of ASOSs' latitude and longitude, because uneven topography and elevated buildings around ASOSs cut off sunshine duration right after the sunrise and right before the sunset. The model produced the sunshine indices for Seoul and Daegu ASOSs with the time interval of one minute and the period of one week for each season and we compared the hourly averaged indices with those observed at the ASOSs. One week of which the cloudiness is lowest for each season is selected for analysis. Not only the adjacent buildings but also distant buildings and mountain cut off sunshine duration right after the sunrise and right before the sunset. The buildings and topography cutting off sunshine duration were found for each analyzing date. It was suggested that, in order to evaluate the observational environment for sunshine duration, we need to consider even the information of topography and/or building far away from ASOSs. This study also showed that the analyzing method considering the GIS data is very useful for evaluation of observational environment for sunshine duration.

In this study, a numerical model developed for sunshine duration based on GIS data was used. This model considers blocking caused by topography and buildings and it is properly applicable to evaluation of sunshine duration environment in urban areas. The model reasonably well predicted the solar altitude and azimuth angels, compared to those provided by Korea Astronomy and Space Science Institute (KASI). The developed model was applied to evaluation of sunshine duration environment around the Seonleung Park located near a building-congested area in Seoul. The model well reproduced shadow caused by buildings and/or topography in the numerical domain at 09:00 on August 1, 2015. In addition, the model was applied to finding a suitable measurement sites for pyrheliometer around the Seonleung Park. The model was also usefully applied to finding a suitable site for pyrheliometer in an urban area.

본 연구에서는 3차원 지형 지물의 일조 차단 효과를 반영한 일조 모델을 이용하여 도시 지역의 일조 환경을 분석하였다. 기존의 일조 모델은 격자셀 단위로 일조 차단 유무를 판별하기 때문에, 건물이나 지형물 모서리 부분의 일조 유무를 판단 할 때에는 오차가 유발될 수 있었다. 본 연구에서는 기존의 격자셀 단위의 일조 판별 알고리즘을 격자셀의 면 단위로 개선하였다. 개선된 일조 모델과 부산광역시 대연동 일부 지역에 대한 지리정보시스템(Geographic Information System, GIS) 자료를 이용하여 계절별 시간별 일조 환경을 분석하였다. 3차원 지형 자료에 대한 계절별 일조 환경을 분석한 결과, 대상 지역 내에 위치한 아파트 단지, 고층 건물, 지형 등의 영향으로 일조량 변화가 발생하였다.

The existing building code regulates the minimum distance between buildings and the minimum required sunshine hours for winter solstice to ensure the right to light. Especially, the minimum sunshine hours have been guaranteed by the constitution after the right for the people to live in a healthy and comfortable environment was established. However, the existing regulation on the sunshine hours only considers the duration of sunshine hours, but ignores the minimum amount of sunlight. Therefore, the calculated sunshine hours are not coincident with the hours occupants actually feel. Therefore, the purpose of this study is to investigate the effect of solar incident angle on interior illuminance distribution, which will be used to propose a new code on the minimum sunshine hours and levels.

본 연구에서는 하의도 남쪽 연안지역을 대상으로 자연적 및 인공적 지형에 의한 일조차단의 영향을 평가하였다. 지리정보시스템 자료를 이용하여 대상지역의 지형공간자료를 생산하고, 태양의 방위각과 고도각을 기반으로 3차원 일조환경평가 모델링을 수행하였다. 주간시간대에는 대상지역의 약 80~90% 이상의 영역에서 일조가 형성되었으며, 특히 하지(여름철)의 경우가 일조환경이 가장 우수한 것으로 평가되었다. 산악지형에 의한 일조차단의 영향은 일몰에 가까운 늦은 오후 시간대에 북쪽 주거지역에서 나타났다. 성토건설에 따라 형성되는 인공지형의 경우, 이른 오전 시간대에는 남쪽 주거지역의 일조환경에 영향을 미쳤으며, 늦은 오후 시간대에는 염전의 남서쪽 지역에 영향을 미치는 것으로 평가되었다.

The objective of the study is to derive the quantitative result and method from the solar simulation on the traditional architectonic control methods and their effects for the sunshine on Ddeuljip in Northern Area of Kyongsang-Bukdo Province, Korea. The Ddeuljip(rectangular-shaped housing plan having an inner court) has distinctive form to introduce plentiful sunshine deep inside to the house in spite of disadvantageous condition resulted from the structure of traditional housing composition, that is, Ickrang(linkage block connecting buildings). From the research on the Ddeuljip, following results were derived: First, in the plan the sunshine environment was improved by placing the master bedroom on the right diagonally, or projecting it toward the Ickrang when there isn't enough space for the inner court and the Daechung(wooden floored main hall). Second in the elevation specific sunshine control methods were developed by increasing the height of the master bedroom, reducing the eaves of south elevation, or differentiating the height of ceiling structure gradually.

In this study, the numerical model was developed to evaluate the observational environment of sunshine duration and, for evaluating the accuracy and utility of the model, it was verified against the observational data measured at Dae-gu Automated Synoptic Observing System (ASOS) located in an urban area. Three-dimensional topography and building configuration as the surface input data of the model were constructed using a Geographic Information System (GIS) data. First, the accuracy of the computing planetary positions suggested by Paul Schlyter was verified against the data provided by Korea Astronomy and Space Science Institute (KASI) and the results showed that the numerical model predicted the Sun's position (the solar azimuth and altitude angles) quite precisely. Then, this model was applied to reproduce the sunshine duration at the Dae-gu ASOS. The observed and calculated sunshine durations were similar to each other. However, the observed and calculated sunrise (sunset) times were delayed (curtailed), compared to those provided by KASI that considered just the ASOS's position information such as latitude, longitude, and elevation height but did not consider the building and topography information. Further investigation showed that this was caused by not only the topographic characteristic (higher in the east and lower in the west) but also the buildings located in the southeast near the sunrise and the southwest near the sunset. It was found that higher building resolution increased the accuracy of the model. It was concluded that, for the accurate evaluation of the sunshine duration, detailed building and topography information around the observing sites was required and the numerical model developed in this study was successful to predict and/or the sunshine duration of the ASOS located in an urban area.

본 논문은 N시에서 발생하는 B와 W 아파트단지 사이의 일조권 침해 분쟁의 연구에 대한 결과이다. 최근 도심에서 발생하는 일조권에 대한 분쟁은 쾌적한 주거의 질을 확보할려는 주민들의 욕구 중대로 인해 그 문제가 점차 확대되고 있다. 특히 건축당시에는 인지하지 못했던 일조권에 대한 문제가 시간이 지나면서 주거환경에 대한 관심이 높아져 그 분쟁의 수위가 시간이 갈수록 높아지고 있으며, 최근에는 도심에서 발생하는 일조권에 대한 해석이 공동주택 건축시 건축법규에 적합하게 설계 시공하여도 인근 아파트에 일조권에 대한 피해를 주었다면 배상을 해야 한다는 판결이 계속 나오고 있는 실정이다. 따라서 본 연구는 이러한 일조권에 대한 영향 및 피해범위에 대해 사례분석을 통하여 파악해 봄으로써 향후 민원발생시 효율적인 대책수립을 위한 기초적인 자료를 제시하고자 한다.
