Every construction company should consider the apartment price when building apartment houses because the sales price has a great impact on the rate of apartment sales. Here, the average apartment price and characteristics of an apartment complex are factors that determine the sales price. However, the existing apartment pricing method fails to properly reflect the weight of each factor. Therefore, the study investigates factors that impact the apartment price and importance of each factor. It examines the apartment pricing method taking into account of the weight.

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.

This study focuses on the fact that the Korean traditional design application appears as one of the trends for a planning technique to express an apartment as a healthy, clean and environment-friendly dwelling recently. Focusing on this, this study tries to apply the characteristic of Han-Ok to an apartment unit plan more compositively beyond the fragmentary design application of existing preceding researches. To do this, the space organization, residential space and housing design elements of Han-Ok are deducted through preceding researches and case studies and proposes a plan by applying this to the apartment plan with a floor plan of about $132m^2$(40 pyeong). The apartment unit plan containing the characteristic of Han-Ok proposed in this study is planned based on the floor plan of about $132m^2$(40 pyeong) which is distributed the most in the city of Seoul. It has an advantage in terms that it can be individually applied not only when a construction firm progresses business anew carrying the banner for a Korean-style apartment but also an existing residents can apply through remodelling. Meanwhile, it has a limit that the diversified space sense and the advantage of an airy Han-Ok cannot be applied to many parts of the design due to the characteristic of an apartment of diverse height change. If a measure to secure constructability and economic feasibility while reflecting diverse differences of floor-level of an apartment can be prepared in follow-up researches, much more various advantages of Han-Ok can be put into the apartment design.

The existing most studies on the apartment sales prices have been limited to relatively small size apartment complexes and have not categorized the apartment complexes based on the number of households. Some of them uses the apartment-related indices such as regional value estimates, sales unit price, and view right values. In the case of Seoul Metropolitan Area, the size of apartment complex has been growing to the level of large complex over more than 1,000 households through new town development, redevelopment and reconstruction. People prefers to choose a large scale complex instead of small complex based on their perception that a large scale apartment complex provides more conveniences in living. The result of this analysis revealed that the variables chosen as important determinants of the hedonic price model for large scale apartment complexes were square meters of apartment unit, rent/price ratio, number of bays, distance to the nearest subway station, and heating system method. This means that the sales price of apartment unit will be higher as the square meters of apartment unit increase, as the rent/price ratio decreases, as the distance to the nearest subway station increases, and as the number of bays increase.

More than 50% of the existing buildings in Korea are over 15 years old. Therefore it is necessary to be held reconstruction or remodeling deteriorated buildings more efficiently. Especially, since remodeling project reserves existing structures, it requires less period of project and construction period compare to reconstruction. It is possible to minimize uncertainty in communication between participants and able to manage information and construct efficiently in remodeling projects. This paper is first step of integrated BIM-based whole lifecyle management of apartment remodeling process. It suggests 3D laser scanner specification factors and site constraint factors for mapping between two groups. Therefore it will contribute to develop mapping algorithm of two groups and find optimal combination for apartment remodeling.

This paper describes the simple payback period analysis of small co-generation system based on the existing apartment and building data. First, We investigate apartment and building data more than $2000[m^2]$ using Ministry of Construction & Transportation's computer system. And then we calculate the latent amount of small co-generation system considering gas company and CHP. Second, we classify the latent amount of small co-generation system into office, hospital, hotel, department store, complex building and apartment. Finally, we perform the simple payback period analysis for small co-generation system. The results show the simple payback period of small co-generation system is less then 10 years.

The purpose of this study is to suggest the improved methods for cost sharing in apartment remodeling projects. Case studies on apartment remodeling projects with different plan type were analyzed and compared. Cost sharing estimated by 'proportional rate method' shows similar results estimated by 'return on investment method' in case of similar area ratio of existing plan to remodeling plan. Otherwise cost sharing estimated by 'proportional rate method' shows great differences comparing the results estimated by 'return on investment method'. Although return on 'proportional rate method' is widely used, it is not proper to estimate cost sharing when each householder's contribution for the project varies, such as considerable differences area ratio of existing plan to remodeling plan. Improved cost sharing method is needed taking into account project contribution and characteristics.

Lately construction industry tends to prefer remodeling of existing buildings rather than new construction or reconstruction of buildings due to strengthening of several restriction related to real estates along with prolonged depression. And also, remodeling of building costs less and creates less wastes compared to reconstruction and so it is more profitable in financial and environmental view. However remodeling is process of creating new environment with existing building. Therefor remodeling must follow the procedure realizing problem and fix the problem based on through investigation on existing building and users requirement must be faithfully reflected. Specially in case of apartment houses, since vagueness on ownership and management authority on common parts exists. Hereupon, in this study we are to present the procedure of analyzing apartment house remodeling method through user requirement by approaching to several considerable factors in user request side.

This study aims at examining the actual conditions of lighting environment and the consciousness and responses of residents with the living room of apartment house, grasping the problems of existing lighting methods, offering the lighting environment design standard in harmony with the various demands of residents, functions of living room space, life in living room and interior decoration and then pursuing the comfortable living environment. As the scope and methods of research for these, existing research methods are examined through the consideration of preceding researches and the basic outline of this research is constructed. Questionnaire survey is conducted with six apartment complexes including Kumho district, Munhung district, Sangmu district, Unnam district, Ilkok district and Chumdan district, the problems and improvements of lighting environment conditions are examined, conception and selection of lighting equipment design image are made, lighting equipment design of living room is suggested and the expected effects of lighting equipment ordering method are arranged as follows. As a result of examining and analyzing the lighting environment of living room in existing apartment houses, it is known that the conditions of existing lighting environment considered uniform lighting plan for functional sides of each room which didn't consider the various living behaviors and preference of residents and while the degree of interior decoration design is actually positive. Accordingly it seems that the lighting equipment ordering which considers the various preferences of residents is applied as the means for comfortable lighting environment, the interior environmental mood will be greatly improved.
