The purpose of this study is to provide a basic data for energy efficient apartment designs by analyzing electricity and gas usage according to horizontal locations of dwelling units in apartment buildings. The data for this research are collected from J-apartment complex, located at 'Wolbae' district in Daegu City. The data are sorted into several groups according to inner and outer locations, East-West locations, and the size of units. By the performance efficiency analysis, the study derives the result as follows: 1) generally inner units are more efficient than outer units. 2) West units are more efficient than East units. 3) The group that is most efficient in overall energy consumption is West-inner units (Group-D) and the least efficient group is East-outer units (Group-A1). 4) However, as units are getting bigger, inner units consumes more energy than outer units because of the gas usage patterns. The study also established cost analysis that shows the cost differences of usages for 30, 40, 50 years between each group. The result says Inner-outer location with East-West location affects a significant amount of the management costs. In terms of economic and social life of an apartment building, energy design standards need to be tuned and make the least efficient units perform as efficient as the most efficient units to optimize the social life of an apartment building.

In this paper we made energy consumption units of glass curtain wall type apartment and general apartment in Busan metropolitan city and compared energy consumption characteristics by building envelope. The monthly electricity consumption units of general apartment were shown in the range of $1.16{\sim}1.51kWh/m^2{\cdot}mon$ which were indicated higher value in January, February, August and September with little variation. On the other hand, in case of glass curtain wall type apartment, monthly electricity consumption units were represented in the range of $1.91{\sim}7.07kWh/m^2{\cdot}mon$ with significant fluctuations monthly, which were outstandingly high in July, August and September. The monthly city gas consumption units of general apartment were found to be in the range of $1.79{\sim}18.07MJ/m^2{\cdot}mon$, while glass curtain wall type apartment were within $0.94{\sim}19.91MJ/m^2{\cdot}mon$. City gas consumption units from December to March were shown highly in both type apartments. The monthly energy consumption units of general apartment were found to be within $14.23{\sim}30.69MJ/m^2{\cdot}mon$, while glass curtain wall type apartment were within $24.49{\sim}68.9MJ/m^2{\cdot}mon$. Energy consumption units of glass curtain wall type apartment were suggested 4.84 times higher than those of general apartment.

Apartment houses are repidly being assimialated into the Korean lifestyle. Little study of space utilization and specificially built-in storage needs has been implemented into design of these apartment units. The purposes of this study were, first, to ascertain attitudes of a select group of Korean housewives(N=250) living in apartments in Seoul toward closets and built-in storage units, and second, to determine the acceptability of proposed alternative plans which include built-in storage facilities by Korean women(N=31) living in the United States. Overall results reflect that built-in closets and storage are highly prized and additional units required in Korean apartment plans. Of the respondents, about 86% thought portable storage bought at marirage would be phased out if more storage was built into Korean apartmemts. Most Korean housewives would perceive the advantages of built-in storage units, and would prefer differentiated built-in storage units to undifferentiat d ones. Yet attitudes were equally split on the aesthetic value of the elimination of the portable storage. Five Korean apartment plans were drawn to scale then altered through the incorporation of additional built-in storage. These altered plans all received greater then 83% preferences to the existing Korean apartment plans. Additional study needs to be undertaken to address the implementation of additional storage in existing units as well as impact the current space planning concepts related to more built-in storage. Consideration needs to be given to the concerns related to aesthetic value of portable units as part of the study process.

In the summer, the irradiated solar heat gain through the roof has an effect on the thermal environment of the top floor units of apartment houses. This paper investigated the differences of the indoor air temperature and thermal comfort index between the top floor unit and the middle floor unit by measuring them at the sample houses. The purpose of this paper is to provide quantitative data about the irradiated solar heat gain during the summertime through the roof of an apartment house and these data to be the source to reevaluate the appropriate roof insulation efficiency. From this study, we obtained the brief results as follows. Indoor air temperature at the top floor unit is $1.2\sim2.2^{\circ}C$ higher than that of middle floor unit. The evaluation of the indoor thermal comfort index at each sample rooms reveals notable thermal differences between the two units. Top floor units need more cooling load during the summertime compared to middle floor units. Therefore, solutions to reduce solar Heat gain at top floor units to be considered.

This study suggested practical considerations in case of planning Small-Sized Household Units of the Vertical Extension of Aged Apartment along with selecting particular Age-Apartment Complex to plan Small-Sized Household Units. Four parts of consideration; (1) Architectural planning aspects, (2) Resident aspects, (3) Structural aspects, and (4) Facility aspects were thoroughly examined to apply in the remodeling construction period. Proposals for Small-Sized Household Units, in this study, covered two different combinations. One was the combination of six equal units, the other was the combination of eleven different types of household units which reflected resident aspects in plan organizations. Plan organization proposal could be chosen and applied to Vertical Extended units by Local Government, Remodeling Association, or Constructor based on their potential residents' aspect, such as family size, life style, age, amount to income and etc. to fulfill their satisfaction. Furthermore, this study had great significance of the adequately reflecting demand on Small-Sized Household Units in Vertical Extension of Aged Apartment.

The concept of universal design has become an essential requirement for environmental design, due to the growing population of the aged, and the increasing needs of people with disabilities. This study aims to propose a universal design guideline for apartment housing units that can be adapted to both a general household and a household with elderly or disabled individuals. This design process encompasses literary reviews, and includes the measurements of the dimensions and facilities of currently available apartment housing. The three domestic universal guidelines were reviewed, and a universal design checklist for apartment housing units was developed. Afterward, the individual elements and inclusive factors of universal design, for apartment housing units, were collected and examined according to the each functional space within the home. The results and conclusions are as follows: 1) The factors of universal design are diversified by the division of the functional spaces within the home, such as the private space, the work space and the entertaining space. 2) Due to the lack of space and storage, wheelchairs cannot be used in most currently available apartment types; this problem can be resolved by applying flexibility and optional adaptation. The solutions for the above are additional design factors that will enable more convenient usage and elaborate design.

공동주택 화재 발생시 인명피해 최소화 및 재실자의 신속한 대피를 위해서는 화재 발생 사실이 경보음을 통해 전체 세대로 전달되어야 한다. 공동주택의 경우 엘리베이터 실과 같은 공용공간에 경종이 설치되어 있으나, 세대내 공간으로 경보음이 충분히 전달되지 못하는 것으로 알려져 있다. 본 연구에서는 실제 공동주택에서의 주,야간 소음을 측정하여 공동주택 세대 내 소음 발생 실태를 조사하고 세대내 공간으로의 경보음 전달 정도를 분석하였다. 엘리베이터 실에서 발생되는 경보음이 공동주택 내부로 전달되는 경우 방화문 및 방문의 차음성능으로 인해 충분히 전달되지 못하는 것으로 나타났다. 공동주택 내에서 발생되는 각종 소음 레벨을 고려하면 공동주택 외부에서 발생되는 경보음을 청취하여 피난행동을 시작하는 데는 어려움이 있는 것으로 판단된다. 이를 개선하기 위해 공동주택 거실의 월패드와 각 방별로 경보음 발생기를 설치한 경우에 대하여 음향시뮬레이션을 실시하였다. 각 방별로 경보음 발생기를 설치한 경우에서만 배경소음 + 15 dB 기준과 75 dB (A) 기준을 만족하는 것으로 나타났다.

Following the previous ones, this study is intended to explore methods of qualitative assessment on the view from apartment units. It first complemented and analyzed the attributes of landscape elements and then set up questionnaire items based on these attributes to identify the tendencies in apartment inhabitants' recognition of landscape elements, and then conducted a preference assessment on the test cases sampled on the basis of picture and other data collected in the previous studies to identify the characteristics of the preference for the view from apartment units according to landscape elements. Consequently, the following results have been derived. First, the landscape elements seen from apartment units may be classified into a total of sixteen categories, and the overall ratio of natural elements to artificial ones is shown to be approximately one to three. Second, it is also shown that apartment dwellers tend to prefer natural landscape elements over artificial ones, and the preferences for the distance to and location of landscape elements exhibit certain variance depending on the type of the elements. Third, the analysis of the preference for landscape elements has revealed that the types of landscape elements, the make-up and diversity of landscape elements, and the perceived distance to landscape elements as well as the resultant feeling of openness all affect the preference tendencies.

The main sources of the new house syndrome(sometimes it called sick building syndrome) are a concentration of formaldehyde (HCHO) and a concentration of total volatile organic compounds(TVOC). I had field measurements of indoor air quality in the apartment unit at medium-size cities(Y city, C city). I measured indoor air temperature, HCHO concentration in 16 units, TVOC concentration in 6 units and air tightness in 7 units. And I measured outdoor air quality, HCHO concentration and TVOC concentration. Mean concentration of HCHO was $357{\mu}g/m^3$(2006 standard=$120{\mu}g/m^3$), mean concentration of TVOC was $3,092{\mu}g/m^3$ and mean effective air leakage area was 193 cm2. There was a close relation between the indoor air temperature and HCHO concentration, between the indoor air temperature and TVOC concentration. Air tightness also had relation.
