The high-rise apartment buildings have been constructed in large quantities to provide housing and used to be the popular residential types in Korea. However, it results that a number of problems are provoked such as the deteriorate of comfort and lack of sunshine access. Based on the judicial precedents, the sunshine access right should be guaranteed to enjoy uninterrupted sunlight for more than two hours continually between 9 am. and 3 pm or for more than four hours between 8 am and 4 pm in the winter solstice. The computer simulations are very strong tools to judge that the sunshine access right is infringed or not. This study aims to evaluate the efficiency of two computer simulation programs such as 3Dmax and Lightscape programs broadly used in field areas. For the study, the three dimensional computer models are suggested, and the simulations are performed on the 30 minutes intervals. Also, the simulation results are compared by the results of scaled model experiments.

Recently, the point of view about housing environment in the city has changed from the traditional point of view of the center of housing to the subject of land- utilization-control for interaction of buildings. Right of light is the center of this issue in other words. Also many interests about the beauties of the city have increasing centering around Europe etc. This is to change a city design into the characteristic design from the exiting uniform design. As if reflect this situation, recently we are setting up the night illumination and constructing a building which acted as Land Mark like the Jong-Ro Tower. And Apartment Housing was being built various form deviate from a existing standardized form and skyline. Existing studies about sunshine of Apartment Housing have dealt with just about a standardized Apartment Housing form. So this study analyzed a recently increasing interest for Right of light and change of sunshine environment on Apartment Housing which have a various skyline form.

The articles on building height limitation are very important to form buildings to be. The application of the articles is based on the surface of the building site ground, that is, the definite judgment of ground level should ensure the correctness of building height limitation. This study surveyed the recognition degree of practitioners about the building height limitation regulations by questionnaires, and analyzed its results and compared them to related building laws and letter of reply from the office to practitioners' inquiry on related regulation. The study summarized the results as follows; 1. It is not clear to judge the ground level. Especially in cases of pilotis structure, there would be various interpretations to define its ground level. 2. According to present building regulations, the site would be confused to define by practitioners whether it is stiff or plain. 3. In case of regulation of a right to enjoy sunshine, it is hard to calculate the average horizontal level(ground level) with neighboring sites. 4. If there were a manual with illustrations for judging and calculating the ground level of various cases, civil petitions would be reduced.

My questionaire survey revealed that even those experts that engage in architectural design did not precisely understand much of the regulations concerning ground-level. In terms of restricting the size of the building area, the generous policy of excluding balconies and basements from the calculation of building size actually causes problems. As far as the right to sunshine is concerned, the weighted average ground-level is determined to be the ground-level standard of the neighboring plot when the neighboring plot is a sloping bare ground. When the difference of heights is over 3 meters, it would be appropriate to assess the weighted ground-level standard every 3 meters.

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.

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.
