Nowadays, architecture in urban areas is dominated by the goal of spanning wide spaces and creating openings large enough to distribute daylight to building interiors. Daylight availability of building in city strongly depends not only on the building's height but also on spaces between buildings. Recently numbers of disputes over the daylight availability are increasing in high density developed areas because residents' demand for pleasant residential environment is getting stronger. Therefore in this study we constructed the three-dimensional information of buildings using LiDAR data connected with digital map and then suggested conclusions by applying it to daylight availability analysis. This study presents an approach to judge accurately the violation of a right to enjoy sunshine by using altitude and azimuths of the sun, simulating three-dimensional urban space precisely, and classifying the total duration of sunshine and the continuous duration of sunshine each householder. We expect that local government performs precisely the confirmation and permission business about urban planning and design by advising this approach.

In this treatise I have advanced a theory to regulate legal problems rationally arising from a right to a view and I have checked some precedents dealing with the temporary injunction, compensation for damage and the demolition of a house(mainly apartment) owing to an infringement of a right to a view. Relating to an infringement of a right to a view, there are more lawsuits which are instituted together with an infringement of a right to enjoy sunshine than lawsuits related only to the right to a view. In the cases of an infringement of a right to a view connects with educational or religious environment, the court made it a decision that the construction is prohibited from constructing more than a certain-story building to protect a right to a view. Plaintiffs won a case their suit in the original judgement regarding a claim for damages owing to an infringement of a right to a view, but the Supreme Court reversed the decision of a lower court. The right to a sky view should not be infringed in case of a dwelling house which is not built for the purpose of business or a view.

This study was carried out to examine the growth condition of Chionanthus retusa, roadside tree in Cheongyechon (CGC) and to investigate the relationship soil characteristics and tree vitality and chlorophyll contents of it. Growth condition of tree (condition of flower, leaves and branch, % of flowering, height, diameter at breast height, width, vitality and chlorophyll contents) and physiochemical relation item (pH, organic matter, K, Mg, Na, Ca, P) were investigated. The result are as follows : 1. The growth condition of flower, leaves and branch in the left side of CGC is better than the right side since the quantity of sunshine of left side of CGC is much more than the right side. 2. The average pH was alkaline. P and organic contents were much lower than the standards. 3. Tree vitality and chlorophyll contents were bad where were high user density and high buildings, such as 1, 2 area near Jong-gak and jongro 3 ga. Among the physiochemical factors of soil which affect tree vitality, K and P were found to be the main factors. Therefore, in order to improve the growth environment of roadside tree in CGC, it is needed to do periodical soil fertilizing and improve physical characteristics of soil such as, permeability and porosity by soil conditioner.

Purpose: As declines in the quality of residential environments occur, such as urban heat island effect, tropical night phenomenon, and violations of right to light and privacy due to urban densification and high rise building, these problems are emerging as social issues. In order to improve these issues, design factors which consider environmental aspects must be selected when planning apartment complexes, and ways to reflect them in the planning phase must be explored. Method: In this study, the analytical hierarchy process(AHP) was used to deduce design factors that considered environmental elements during the planning of apartment complexes. Furthermore, the priority and weight for each evaluation index were assessed. The objective was to propose a guideline for planning apartment complexes by finding the best solution for each evaluation index using complex weight values. Result: Floor area ratio was selected as the most important evaluation criterion in the environmentally conscious evaluation index for apartment complex planning. The shape and placement of skylights were selected as the most important evaluation criteria in the sunshine environment for a pleasant residential environment. Ground surface cover design was selected as the most important criterion in the outdoor thermal environment index for improving the microclimate within cities and apartment complexes. Thus, the results of this study can serve as an investigation guideline that concerns policy and regulations, and as reference data that can be used in planning apartment complexes.

Nowadays, the solar expose right is very important with people's life. Therefore, in calculating the sunshine hours, the point analysis and area analysis methods are used in previous studies. Previous two methods have merits and faults. Therefore, ray-tracing method is used as a alternative. Ray-tracing method is adopted by the software of Autodesk Ecotect which is a widely used program by the architectural company and academic university. In this study first, ray-tracing methodology is studied with how to calculate the overshadowing area and, secondly, the sensitivity of the two major factors, overshadowing accuracy and sky subdivision, is analyzed. With these results, appropriate application of the ray-tracing method is presented.

In case of Korea, immovable property like location, land prise or investment value is more highly estimated than quality of life of residents for performance and value of apartment house, because of limited land area or high density of population. But the high level of life has recently caused the increasing demand in better life. As there is no cases to provide the house in bulk due to the housing market condition, it is necessary to evaluate performance and value of structure, disaster prevention safety, habitability, antiquated condition of building and equipment, maintenance condition and so on that has importantly influence on resident's life quality. So, this study aims to understand the actual condition of environmental performance for the present apartment by comparing the designated apartment, which is ready to have completed in Daegu, with the mixed use residential building, which gained the best grade for green building certification system. Also by analyzing and evaluating a right to enjoy sunshine, floor impact noise etc. and indoor air quality.

As construction project is becoming larger, construction progress and works are more various and complex according to recent Korean construction tendency. The growth of construction induces much pollution on the progress of construction and the problems due to the construction pollution are raised into social problem strongly, because it is increasing the need on the quality of lift and the desire of clean environment. This study aimed to seek far the effective solving plan of the construction popular complaints by surveying the real condition of construction popular complaints and analyzing the cause and tansaction period of popular complaints. For this study, the laws related and popular complaints were analysed focusing on the documents in low district offices of Gwangju from 2000 to 2004. As a result, the types of construction popular complaints were divided into 17 and the causes were as follows in order: crack and subsidence of ground(14.90%), infringement of private life(11.55%), noise(10.80%), infringement of a right to sunshine(10.07%) and breakdown(6.7%). Consequently, it is considered that these complaints are occurred by physical and environmental causes.

This study examined and analyzed uses, transformations, changes of plane and arrangement, and changes of space structure of housing components with traditional folk houses located at Kyideok village, Hanrim-eup, Jeju, and the results of the study can be summarized as follows. First, the exposure of arrangement of folk houses at Kyideok village, Jeju was evenly distributed to the east, the southeast, the northeast and the west in order and it was little different from the use of sunshine conditions by placing the main room on the south in traditional houses of land areas. Second, the space structure of inner room before transformation was divided into seven types. 3-room type was classified into "Sangbang-centered three-room type" and "nanggan-centered three-room type", 4-room type into "four-room type with inner access to warehouse", "four-room type with outer access to warehouse", "kitchen-divided four-room type", "four-room type with two kitchens", "four- room type with nanggan at the right back". Third, according to types of change in arrangement type, the first is new annex addition to existing inner room, the second is the removal of existing annexes including outer room, the third is the extension of inner room size without new construction of annex, the fourth is new construction of annex with new plane form after removal of existing annex, the fifth is no change in arrangement of inner room, outer room, stable, warehouse, etc. Fourth, transformation of space components led to changes of space structure as well as those of plane form. Changes of space structure were divided into reduction type of circulation to specific factors, negligence type without using increased space factor, and addition type having various circulations through the increase of convenience space.

Apartments with a southern exposure are often thought to have advantages in receiving winter sunlights and summer natural ventilation. However, as due-south-apartments increase recently, the consideration for residential environment for households with no southern exposure is necessary. In case of due-south-apartments, residents prefer east-sided apartments than west facing apartments which might receive more hot sunlight in the afternoon; however in case of west-oriented apartments with active ventilation, the interior area is bright until late afternoon without unpleasant heat and has advantage in light environment aspects. This study aims to compare and analyze merits and demerits of air flow and sunlighted environment of buildings through sunshine duration simulation using CFD simulation ad sunlights about southeast-sided and southwest-sided apartments based on general opinions for apartment directions. As results of the interior natural ventilation analysis, as the average air flow speed in southwest-sided apartments was 1m/s faster than that of southeast-sided, it has effects of lowering sensory temperature of residents in summer, and for sunlighted environment, southwest-sided apartments are advantageous for sunlighted area for duration time inside. As a result of the research, the calculation of physical residential environment of apartment residential space should be reached through integrated evaluation of natural ventilation and sunlighted time from placement and facing direction of the buildings considering characteristics and environment of each apartment, not based on general opinions.
