This is study on the glazing performance of the apartment house to predict energy saving rate when the early design stage by calculating heating load. there are various factors of the window type in apartment building to save energy such as window's U-value, SC or SHGC, window wall ration, frame factor, sunshade coefficient and so on. In this study, we analyzed the heating load focused on the U-value, SC and window wall ration using variable heating degree days method for a small and middle size units $59m^2$, $84m^2$, respectively. Each cases were calculated heating load of the real models compared to standard model to predict energy saving rate. From those cases it was drew the conclusion that were window's U-value, SC and window wall ration for the small and middle size units to expect 10% energy saving rate at least.

The basic premise of this study was that the elderly family would be one user type to live in apartment houses. This means that apartment houses should be designed by considering the elderly family as well as general young families. The purpose of this study was to carry out POE of apartment houses by the elderly resident and to suggest the design direction of apartment houses from the elderly's point of view. The subject was 150 elderly residents who lived in apartment houses in Jangyu new urban area, Kyungnam. The individual interview was done for this POE by six interviewers. They asked about how degree they were satisfied with 30 design elements of apartment houses. Those consisted of 8 elements related to outdoor environments, 16 ones to indoor environments, and 6 design evaluative elements for the elderly housing. The conclusions were as followings; 1) In general, the elderly subject was very satisfied with their apartment design. However, more considerations of the design evaluative elements for the elderly were needed in order to be apartment houses for the old generation. 2) Natural facilities such as small parks and walks, and local amenities should be arranged systematically to be used easily by the old residents. 3) The design solutions for reducing noise should be added. 4) The same quality of housing environment should be provided in all sizes of housing units.

As customers are becoming increasingly important in corporate management, there is a growing demand for migration to customer-focused organizational structures. Unlike the manufacturing industry, the construction industry is non-iterative and non-standardized. As a result, a wide variety of materials, human resources, technologies and equipment must be mobilized in complex work activities to complete a structure. Consequently, surprises are bound to occur as such work activities progress. This paper intends to study a strategy that is designed to improve customer services for apartment building units. It aims primarily to focus on cost control and brand management. Housing tenants and industry experts are surveyed to collect input for issue analysis. In addition, the external circumstances and internal capabilities of major builders in Korea are analyzed, and a SWOT analysis is performed regarding market conditions related to customer service. These analysis results are utilized to develop a strategy implementation plan over different time frames, and the operational resources available for such strategy implementation are analyzed in order to forecast its performance. This research will facilitate communication between construction companies in Korea and their customers by proposing a customer service improvement strategy for apartment building units, and is expected to provide resource material for a strategic analysis of efforts to fully incorporate customer requirements

In this study, annual site and primary energy use intensities (EUIs) and CO2 emission intensities (CEIs) per area by end use were estimated based on the measurement data from June 2016 to May 2017 of 50 sample apartment units in Seoul. In addition, estimated site EUIs by end use were compared to the U.S. Residential Energy Consumption Survey (RECS) 2009 data. Site EUIs by end use were found to be in the order of heating > electric appliance > domestic hot water > cooking > lighting > cooling > air movement. In the case of primary EUIs and CEIs by end use, electric appliance was found to be the largest. As results of comparison with the RECS 2009 data, it was found that site EUIs were very similar for heating, domestic hot water and electric appliance, etc., but slightly different for cooling. The number of sample apartment units will continue to increase until 2020 (total number of samples 200) and intensities data by end use will be continuously updated through continuous collection of measurement data.

The purpose of this study was to determine the present condition of sick house syndrome of newly built apartments a mid-sized city. The questionnaire survey was carried out from $19^{th}\;to\;22^{nd}$ of May 2004, with respondents consisting of 160 households living in two apartment complexes of Cheongju. Their residency periods after moving in were within $six{\sim}ten$ months. From the survey results of the respondents, sick house syndrome items revealed high percentages with the highest value of 49.3%. The respondents answered that they knew relatively well about sick house syndrome but they had no knowledge about 'bake-out'. The response percentages of sick house syndrome items in E complex, consisting of $106m^2$ (32 pyeong) size units, were significantly higher than those in A complex, consisting of $76m^2$ (23 pyeong) size units. This result suggests that the pollution levels emitted from interior materials in larger sized apartment units are higher than those in small sized units. The response percentages of sick house syndrome items in houses with fulfilled ventilation which had been ventilated before or after moving in were lower than in houses not ventilated.

This research is carried out to investigate the Condominium Management System of the states of California and Hawaii, and to examine the similarities and the differences between the Korean Apartment Management System and the American Condominium Management System. The research indicates: first, in Korea the management of apartment units is the Commission of the Representatives of the Occupants, while in America the management of condominiums is the Association of Apartment Owners, an organization of condominium owners in America. Second, it is required that apartment developers should submit such a document as the Public Report in America, which explains various matters concerning legal rights on condominium buildings and the outline of the buildings, to the authorities concerned in Korea. It can help the authorities to accumulate management techniques of the apartment complex, which could efficiently be used in practicing and planning city housing policies. Third, each apartment's management company in Korea is bound to make long term plans for maintenance based on the Housing Law. It is, however, difficult to reserve an adequate amount of money for the reserve fund, because its use is decided according to the maintenance rule which has a criterion different from each and every apartment management. Concludingly, an amendment of the Housing Law in Korea is required, in order to reserve at least 50 percent of the estimated sum of maintenance expense in future like Hawaii State in America.
