This study makes three apartment building complex an object of analyzing representative building types and energy consumption rate of house holds, and effect of outdoor air cooling. Recently created apatrment complex is composed of very various types of building, plan, and orientation etc. But, it is difficult to remark conclusively that these various types of buildings are designed energy-effectively. Because architects are hard to find useful energy design guideline for decision making. By the preceding study, the present condition and problem about this subject is grasped, apartment building types were examined and representative types were extracted. In this study, energy simulation was conducted, and the effect to outdoor air cooling was analyzed about representative types of the subject apartment complex. It is expected that this analysed results will be basic data for the more integrated study. Research consequence can be summarized as follow: 1) Besides solar gain, household layout of building, orientation, and plan etc. effects compositively on energy consumption rate. 2) The effect of ourdoor air cooling in building of tower type can be improved by arranging households appropriately.

This study explores the causes and processes of morphological transformation of apartment complexes in Busan. All apartment complexes built until the year 2016 were selected for statistical analysis, drawing/map examination, field observation, selected expert interviews based on 6 periodical groups: Period I(~1990), Period II(1991~1995), Period III(1996~2000), Period IV(2001~2005), Period V(2006~2010), and Period VI(2011~2016). The research argues for three 'arrangement' types, P1U, L1U and P2U, which have dominated the whole periods occupying 88% of the total 260 complexes. The switch of the leading type represents for morphological transformation of apartment complexes. Four aspects, density(F.A.R.), height(maximum number of floors), deformed-building-type ratio, and building-orientation, have affected the change of 'arrangement' types. Density was the major cause of the arrangement-type switch, from P1U to L1U, on Period II(1991~1995). The morphological change, from type L1U to P2U, on Period V(2006~2010) was caused by height and orientation, and is correlated with the increased number of deformed-type buildings. The first phase morphological change on Period II(1991~1995) was resulted by the supply side of apartment. However, the second phase transformation on Period V(2006~2010) had gone through the complex process including reflection of consumers' demands. The significance of research is to reveal the morphological transformation process of apartment complexes through analytical investigation of the entire apartment data in Busan. The result shows that the major change of urban paysage started to occur from Period V(2006~2010), and the superficial evaluation on apartment 'being monotonous and repetitive' may not be proper at least from the perspective of town plan.

The populations of major cities in Australia are increasing rapidly and facing an acute housing shortage. Traditional apartment procurement techniques involve lengthy lead-times and factory-based, or offsite manufactured (OSM) multi-storey apartment buildings may offer the opportunity to help fulfill the need by significantly reducing build times. Other advantages of OSM may include superior quality, low weight ratios, economies of scale achieved through repetition of prefabricated units, use on infill sites, sustainable design standards and better occupational health and safety. There are also positive labour and training implications, which may help to alleviate an industry-wide shortage of skills through use of semi-skilled labour. Previous uncertainties about the adoption of offsite due to the high capital costs and perception issues were generally based on pre-cast concrete structures, which are quite a different building type in terms of flexibility, construction, delivery and finishes. Identification of drivers and constraints assists in the determination of current industry status, allows for a benchmark to be established and future opportunities and directions for OSM to be determined.

Apartment Buildings have particularity to cluster together, especially, floor is close to resident, it is subject to dissatisfaction about impact noise between up and down floors. However, we require standard for counterplan to reduce the impact noise of floor. In point of fact, it difficult to objective evaluate for performance sound insulation that not physical sound volume but orignal form, means and effect of sound caused to complex noise in apartment house. Unique type of dwelling and structure pattern cause to noise of floor impact which is established by law for standard regulation. It is object to analysis and compare the result of performance sound insulation of upper floor impact and sample construct the subject resilient material of sound insulator

The purpose of this study was to find, through field and questionaire survey, the problems in arrngement of reinforcing bars in wall-slab type apartment buildings. The survey was done in 88 construction sites over the country. The findings from the survey were as followed : (1) reinforcement details were unnecessarily complex in some structural members and could be simplified without sacrificing the safety of the structures; (2) It was found in many cases that drawings of reiforcement failed to show the location of the laps, bent-up positions, and the development length; and (3) it was often found that the workers did not understand the importance of tloerence limits and anchorage in the steel bar arrangement.

With an awareness of the fact that influence of building industry on the environment problems is great, many countries have been endeavoring to construct sustainable and environmentally-friendly buildings. In Korea, the GBCS (Green Building Certification System) has been in force since 2002. Total 6 types of buildings are dealt in the GBCS. Especially, it is expected that the number of apartment complexes, which are the most common type of residences in Korea, applying for GBCS has increased continuously. In this study, we aim to pick out the items requiring improvement for the green apartment complex. Existing 12 certified apartment complexes were selected. GBCS assessment results and actual conditions of design and construction were investigated and analyzed. Total 18 items requiring improvement were picked out in accordance with the average score-to-allotted point ratio. Relevant particulars expected to be helpful for the next design works were also presented.

In Korea, apartment complexes are built according to the social strata for which they are intended to house, thus the buildings tend to separate society both physically and even visually. Because of the sense of social exclusion this has caused the government has conceived a plan to develop a "social-mix" apartment complex master plan. Perhaps the foremost example of this type of plan is the Seoul Eunpyeong New Town. This study examines how resident's perception of the social mix plan has evolved, and also attempts to better understand the effectiveness of the government's attempt at social integration. The result shows that the perception of social-mix housing has improved after residents moved into the Eunpyeong New Town and that people responded positively to the concept of actually mixing residents socially. From the result, we can see that the visually unexposed environmental elements of rental housing and socials exclusion which was felt in the past has been reduced to a certain extent. However, residents living in solid-lot apartments have a negative reaction to social mixing especially when they are in the same building. Therefore, to achieve better social integration in a socially-mixed apartment complex, we need now to change the perception toward socially mixed housing among the residents living in solid-lot apartment buildings.

최근 중국과 튀르키예에서 발생한 지진과 함께 세계 곳곳에서 지진으로 인한 피해가 발생하고 있으며, 그 피해의 정도 또한 매우 심각한 상황이다. 지진 활성단층에 위치한 우리나라도 더 이상 지진의 안전지대가 아니며, 지진에 대한 선제적 대응이 절대적으로 필요한 시점이다. 정부에서는 기존에 지어진 공공건축물에 대한 내진성능평가, 절차, 내진보강 방법 등을 마련하여 내진설계가 미흡한 시설물에 대한 내진보강을 추진하고 있다. 하지만 민간 소유의 아파트는 강제할 방법이 없고, 사전 연구와 가이드라인의 부족으로 국민 안전을 위한 선제적 조치가 매우 미흡한 실정이다. 국내 주거용 건축물의 약 48%가 30년 이상 된 노후 건축물이며, 그 중 공동주택은 80% 이상으로 그 심각성을 뒷받침하고 있다. 본 연구에서는 건축물의 내진설계 기준을 기반으로 지반 유형, 건물의 중요도, 노후도, 층수 등 공동주택의 내진보강을 위한 총 7개의 주요 영향 요인을 도출하고, 내진보강 우선순위를 보다 간결하고 효율적으로 결정할 수 있는 알고리즘을 제안하였다.
