From Feb. 2006, the ventilating systems with air exchange rate of over 0.7times/hour are installed at the apartment houses (over 100 units). Installation cost and maintenance cost are very important factors for ventilating system because consumers have to pay the expenses of that system. Especially small apartment needs more considerations because small apartment is comparatively the economically weak part. The purpose of this study is to the performance evaluation of the hybrid ventilation system for small apartment houses. Hybrid system 1 consists of natural ventilation system and duct type exhaust diffusers. Hybrid system 2 has natural ventilation system and toilet exhaust system with static pressure fan. Infiltration of test apartment houses with ventilation system is under 0.1 times/hour. Mean air age of hybrid system 1 is 1.52 hours and hybrid system 2 is 1.42 hours. Mean ventilation effectiveness of hybrid system 2(93%) is higher than that of hybrid system 1(81%).

The purpose of this research is to set a standard for deciding competitive marketing prices of new supplying apartment houses and to analyze decision factors in sale price of supplying apartment houses with Analytic Hierarchy Process; the resulted model does not use the method that joins the land cost and the cost of construction together, but the method that compares the sales prices of surrounding apartments. This research tries to set a standard for decision of the prices of newly supplying apartment houses by classifying the determinants into the $1^{st}$ step(4 factors), the $2^{nd}$ step(9 factors), and the $3^{rd}$ step(25 factors). According to the process, the relative importance of decision factors in the sale prices is determined and this should be used as the index of sale prices for newly supplying apartment houses when the houses are provided. In addition, through the $2^{nd}$ step including 9 factors, the comparative model for sale prices is defined and the model is presented to be applied in the real business. Subsequent study additionally considering the factors apart from marketing which tries to find a generalized standard needs to be conducted.

The recent increase in lawsuits and disputes caused by defects in apartment houses has been highlighted as a social issue. To solve this problem, studies were conducted on the type of defects in apartment houses. However, the problem has not been resolved amicably. Accordingly, it was emphasized that it was necessary to lay a groundwork for research on the types of defects by type of construction work in the recently constructed apartment houses and to present countermeasures and preventive measures for defects later. Therefore, this study investigated cases of defects in apartment houses and analyzed types of defects through PMIS and defect reports. The main purpose of the research is to present the causes for major types of defects by identifying the types of defects in apartment houses and to lay the goundwork for the study of countermeasures and preventive measures for each type of defects in the future.

In this study, the CO₂ emission and economic efficiency of high-rise apartment houses were evaluated, and were analyzed as a way to establish database on the evaluation of environment-friendliness of high-rise buildings. To that end, standard of buildings to be evaluated were proposed through analysis of the designing guideline for high-rise apartment houses proposed by Seoul city, and CO₂ emission of the subject buildings were evaluated based on the characteristics of materials admitted into each building and the amounts of energy consumed during lifecycle period. In addition, the initial costs in construction stage and annual costs in operation stage were set as analysis parameters, and along with calculation of direct cost by the consumption of construction materials and energy, the costs of CO₂ emission were evaluated and analyzed. As a result, the CO₂ emission and economic efficiencies of high-rise apartment houses by construction stage and operation stage could be analyzed quantitatively.

This study was intended to suggest that new small-sized apartment houses should be designed and provided on the base of the concept of universal design. This is based on the diversity of each resident, that is, resident of not as a family, but as an individual. On the background of this, this study evaluated the small-sized apartment house in aspects of universal design. The walk-through and the residents' evaluation were carried out by using 60 items related to the principles of universal design. The 18 pyung apartment complex and housing unit in Jangyou new town area was evaluated. Also, 100 residents living in that apartment housing unit were asked to evaluate these 60 items by using 5 point Likert scale. The walk-through with measuring and taking pictures was carried out by researchers. In general, the apartment house was not met the fundamental elements of universal design. Thus, it was not appropriate for the disabled or the elderly to live in. Specially, the door width of bathroom and kitchen balcony was too narrow to pass through. Also, the floor of entrance and bathroom was not flat, so that the wheelchair user cannot enter by alone. The residents evaluated negatively many items related to design, such as shape, color, and material. Therefore, in order to provide the living environments for diverse residents such as the elderly, or the disabled to live together, the new small-sized apartment houses should be designed on the base of the principles of universal design.

This study aims to analyze the current status and characteristics of apartment house unit plans towards spatial differentiation. The 172 house units from 32 housing complexes were selected for this analysis. In this study, factors of residential space plan especially in an apartment house are categorized into general characteristics on floor plan and factors for spatial floor plan. The Primary findings are as follows: (1) General characteristics on floor plan are analyzed based on space organization, area and number of bays. Among apartment houses over 40 pyeong, it seems that differentiation is well applied with various space plans available. (2) A result of an analysis on the factors for spatial floor plan shows that planning a living room with two-open-sides seems to be more common in the tower-shaped apartment blocks which are now on the increase. Moreover, many of them are adopting movable partitions to reflect resident's various demands on space plan. Among all, the extra kitchen in the balcony is planned high portion of 80.4%. And diningroom is positioned on the front side of the residential space along with a livingroom(19.2%). More frequently, dining area tends to face the living room(30.2%) according to the result. Besides dress rooms begin to be placed in each of the bedroom, once planned in one bedroom only while 18.6% of the apartment houses are placing new storages in the entrance to solve lack of storage space due to balcony extension.
