The purpose of this study is to classify defects of the residential building by analyzing the defect specified by prequalification of residential building reconstruction and to suggest the solution of the problem which can be arisen during each stage of plan, construction and maintenance. By sorting the main defects which is specified by pre-qualification of residential building reconstruction for three years from August 2006 to August 2009 into 4 catagories and analyzing the cause of the defects, we draw the way of maintenance to prevent the defects and make pleasant residential environment. The reason for the frequent defects from residential building is mainly deterioration. It occured on the finishing more than on the structure, which means that residents can find defects easier on the finishing than the structure and clear the demand for repair. The result of analyzing of pre-qualification of residential building reconstruction is that the defects mostly caused small, masonry constructed and lower apartment. The apartment which is not into legal right for maintenance naturally have more defects than the others. In conclusion, it is necessary to establish a law of obligation duty of the maintenance of small apartment.

To make a prediction for a change of residential environment caused by the building code in Seoul which includes loosening the distance between multi-residential buildings, proposals of the four main building arrangements by analyzing examples were selected and then, amount of daylight and view efficiency were analyzed and presented through computer simulation for the proposals. In the result of the analysis, there was a difference among the arrangements but, when the distance between buildings was applied 0.8H as the least, residential environment like daylight and view efficiency per unit significantly decreased in quality. Particularly, for the middle stories(6-15) and the high stories(16~24), when the distance between buildings decreased from the current measurement, 1.0H, to 0.8H, the analysis indicated that 28% of daylight and 7% of view efficiency were reduced. In the building arrangements, an order of the best residential environment was followed in this sequence; balanced arrangement of flat type as the best, combined arrangement between L-shape and tower types, balanced arrangement of tower type, combined arrangement between flat and Y-shape types, grid arrangement of flat type, and combined arrangement between Y-shape and tower types as the least.

The Korean government plans to introduce the building energy performance standard which regulates the annual energy consumption of buildings. This paper aimed to set up the reference building from database based on the building design trends for non-residential buildings. We surveyed the design data of 435 non-residential buildings which were granted building permission from 2007 to 2011. And we conducted estimation on the heating & cooling load and the energy consumption of the reference building using ECO2 program. From results, the reference building of non-residential buildings was office building which had a total 7 floors and $20,838m^2$ gross floor area. And it suggests the design reference data of building envelope, HAVC, heat source equipment and lighting system for the reference building. The total annual energy use of the reference building was $151.9kWh/m^2yr$.

The purpose of this study is to analyze architectural plans of lower part of super tall mixed-use residential building for understanding its functions for urban. The area of this research are limited to super tall mixed-use residential building which were built in Seoul, Kyoung-gi area, and new towns. For this purpose, theories for super tall mixed-use residential building and non-housing parts were researched, and characteristics of selected cases for field research were analyzed by studying drawing materials. The research focused on scale, type of building, included programs for public spaces, and characteristics of location. As a result, every cases were designed as 'outdoor transition zone-centered type', and for urban function, non-housing facilities were condensed to increase convenience. In addition, ratio of non-housing part were incresesed with public spaces design for residents, and various programs were inserted.

The fire in Ulsan in 2020 was a 33-story residential and commercial complex with about 90 injuries and more than 10 billion won in property damage, and considering the recent increase in high-rise residential and commercial complexes, the risk of similar fires is high. As can be seen through the residential and commercial complex fire case in Ulsan, life-based fire safety standards need to be established to minimize casualties. Therefore, the purpose of this study is to draw improvements for the development of human safety standards for high-rise residential facilities in the future through comparison with the Korean Building Act, Firefighting-rellated Acts and the U.S. NFPA 101.

The purpose of this research was to analyze the correlation of residential satisfaction and the size of housing unit in apartment housing through the case study of 1,619 samples of 36 housing estates. The contents of this research consisted of two main parts. The first part was to identify the differences of residential satisfaction of dwellers, based on the size of housing unit, in apartment housing. The second part was to analyze the characteristics of residential environment, which might have an influence on the differences of residential satisfaction. the findings of this study were that the residential satisfaction of dwellers was proportional to the size of housing unit except $39m^2$ under housing unit, and the size of housing unit was not proportional to the residential satisfaction of outdoor openness exactly, but the size of housing unit was proportional to increase of the distance between building and building, and decrease of the building surface coverage ratio to outdoor area. This research will contribute to the establishment of the site planning methods which increase residential satisfaction in apartment housing, while promoting the quality of residential environment in Korea.

In addressing the goal for sustainability in the construction industry, the very materials used for construction and the methods utilized to implement said materials must be analyzed. Specifically, some traditional residential construction materials consist of wood, steel, and concrete. Because these materials vary in their levels of sustainability, there is a need to develop and explore new or other materials that can be used for residential construction. The primary purpose of this paper is to provide a review of interlocking earthen masonry units (IEMU) as an alternative option for residential building construction. This is in an effort to explore the variables impacting their existing and potential applications as sustainable materials and a method for residential building construction. IEMU's are then examined under the triple bottom line (TBL) sustainability framework which includes analyzing the environmental, economic, and social sustainability of IEMU's. The findings of this review may lead to further progression in the development of a framework for evaluating U.S. stakeholder adoption of IEMU's and potential implementation in U.S. residential construction.

Residential Buildings should provide high-quality, comfortable environments to support the activities of their occupants. The indoor environment of residential buildings, which includes thermal, lighting, acoustic, and indoor air quality, has a significant impact on health and quality of life. The comfortable living environment in residential buildings result from appropriately combining these environmental quality factors, and the performance of building systems must be compatible with the activities of the occupants. The objective of this research is to investigate and analyze the relationship between physical environmental conditions and occupant responses for improving environmental quality (EQ) in apartment buildings with four different building orientations (i.e. E, W, S, N) in two different seasons (i.e. winter and summer). The occupant survey was conducted in actual apartment buildings. The Physical environmental conditions in apartment buildings differed substantially depending on space, outdoor weather conditions and building orientations. Each space within the same apartment building had different environmental conditions. Combinations of unbalanced physical environmental conditions in apartment building decrease occupants' satisfactions and their perceptions of overall residential quality. Occupants' satisfaction and their responses to physical characteristics of their residential environment is related to thermal, lighting, acoustic, and indoor air conditions in their buildings. The result from this research will help designers and researchers to identify problems and develop solutions for improving environmental quality from the occupants' point of view.
