In Korea, multi-housing in one of the most common types of residential space due to its easy management and convenience. In particular, south-facing plate-type(一) multi-housing has attracted a great deal of public interest because it consumes less energy compared with other types of multi-housing, making it advantageous from an energy-saving perspective. Although there have been many studies on the annual energy consumption of multi-housing in relation to building shape and area of window, there have not been sufficient research on the annual energy consumption of multi-housing in relation to individual units of the multi-housing. The purpose of this study is to propose a strategy for reducing energy consumption in plate-type(一) multi-housing, taking the units with the lowest energy consumption as the standard. The result, Standard Models's energy load was as 4000 ~ 5600kWh, and Passive Houses's energy load was less than Stand Models at the 1600kWh.

In research on housing welfare policy, there has been little interest in middle-aged households compared with young or elderly households. The purpose of this study was to explore influences on the housing satisfaction of middle-aged renter households using microdata from the Korea Housing Survey 2021. A statistical analysis of data was performed on a total of 2,709,152 middle-aged (aged between 40 and 64 years) Jeonse (lumpsum housing lease) renters and monthly renters with deposits, living in private rental housing units. The major findings were as follows. Firstly, there were significant differences in housing unit satisfaction and residential environment satisfaction among renter groups by age and rental type. Early-middle-aged Jeonse renters displayed the highest satisfaction with both housing units and the residential environment, while semielderly monthly renters with deposits displayed the lowest satisfaction. Secondly, living in aged structures or in apartment units exerted the strongest influences on housing satisfaction, which implies the need for residential area regeneration programs that consider the situation of rental households. Thirdly, living in Incheon and Gyeonggi-do was found to have a negative influence on housing satisfaction. Fourthly, upward filtering on tenure types or lease renewal of the current house did not necessarily have a positive influence on the housing satisfaction of middle-aged renters. Based on the findings, suggestions were made to improve the housing situation of middle-aged renter households.

Although the term royal floors is broadly used in high-rise housing, it is hard to find any clear scholarly definition of this term or any in-depth study exploring people's perceptions of it. This study reviewed ongoing discussions about concepts and definitions regarding royal floors, collected opinions from high-rise housing residents and realtors about the term, and compared the opinions of these two groups. First, the statistically analyzed results verified five main factors affecting people's perceptions of royal floors: locational characteristics (i.e., daylight, view, orientation), 2) price characteristics (i.e., premium, price increase level, number of houses on urgent sale), 3) best location of apartment building (i.e., location within a neighborhood, unit size), 4) architectural characteristics of apartment complex (i.e., size of complex, housing type, size options of units), and 5) personal characteristics of respondents (i.e., personal concepts of the meaning of housing, lifestyles). Results from the analysis showed that realtors perceived strong relationships between royal floors and 1) locational and 2) price characteristic factors, while residents perceived strong relationships between royal floors and personal preference as well as three factors from the five identified above: 1) locational, 2) price, and 4) architectural characteristics. Third, in defining royal floors in a building, the past rule of 1/4 is no longer effective. Instead, the rule of 1/n has become more prevalent (i.e., 1/6 to 1/8). Fourth, royal floors can be defined as the 15th to 25th floors in a 30-story high-rise housing structure based on the agreement of 50% of residents and 70% of realtors.

최근 공동주택의 유지관리를 위한 인건비, 에너지비가 급속하게 증가하고 있다. 이에 따라 설계단계에서 이 비용을 절감할 수 있는 기법의 필요성이 제기되고 있다. 공동주택에 있어서는 대부분의 경우 세대당 동일한 내외벽, 창호 등이 반복적으로 사용되므로 단위평면의 LCC 최적화가 전체 건물의 LCC 최적화에 있어서 가장 중요하다. 이를 위하여 본 연구에서는 LCC 비용항목 중 공동주택의 물리적 시스템에 탄력성있게 변화하는 LCC 비용항목을 파악하였고, 초기건축비, 보수교체비, 에너지비를 종합적으로 최적화시킬 수 있도록 LCC 부위단가 개념을 도입하여 공동주택 적정치수 산정방법을 제시하였다. 여기에서 보수교체비산정은 보수교체비용 최소화에 의한 최적 보수교체주기법에 근거하였으며, 에너지 소비량 추정은 DOE-2에 의한 동적 에너지 부하량을 추정하여 LCC 부위단가 개념에 접목하였다. 보수교체비 최적화 기법과 동적에너지 분석에 의한 LCC 부위단가 개념은 기존의 개념과는 다른 독창적인 개념이다.

Before occupation of an apartment housing, the builders are required to inform the test result of IAQ to the public. However, there is no simplified method to predict IAQ before measurement of pollutant concentration. In this study, a simplified way of predicting IAQ based on the distribution of indoor pollutant concentration is proposed. 7 different cases of air change rate have been simulated through CFD analysis to get the distribution ratio of each pollutant material and then simplified functions were used with CRIAQ1 values derived from CFD simulation to evaluate by comparing the influence of each material in the indoor pollutant concentration. Again, a lot of efforts which can improve the indoor air quality have been performed. Materials used in indoor space are labeled with their pollutant emission level. Installation of ventilation system in residential buildings will be regulated by a building codes sooner or later. But it is important to understand the fact that layout of walls, location or size of openings will influence the indoor air flow and pollutant concentration. And location of emitting material influences to indoor air pollutants distribution. But until now there is few recognition and consideration of these factors. Therefore, in this paper the effects of these factors is proved and some kind of guideline is made for designers after a comparison of typical apartment floor plan and a new type plan with their average pollutant concentration and its distribution of each room. CFD(Computational Fluid Dynamics) program was used to show the indoor air flow and pollutant concentration distribution. For this purpose, a typical $100m^2$ apartment floor plan was chosen as a case study model and several alternatives were reviewed to improve the IAQ performance. The simulation took place in the condition of natural ventilation through windows.

지속가능한 발전을 추구하는 최근의 추세에서 해체산업은 자원의 재활용이나 재생측면에서 중요성이 더욱 커져가고 있다. 주택건립 및 기존주택현황을 고려할 때 해체시장의 규모는 계속 증가될 것으로 예측되고 있다. 따라서 지속가능한 발전을 위해서는 해체폐기단계에서 발생하는 건설폐기물을 정확히 예측하고 관리하는 것이 필요 하다. 그러나 국내에는 이러한 폐기물을 예측하기 위한 모델의 개발이 미흡하고, 또 이를 적절히 관리하기 위한 시스템의 개발도 이루어지지 못하고 있다. 따라서 본 연구에서는 공동주택 및 단독주택 등의 건설폐기물의 발생을 예측하기 위해 원단위를 개발하였다. 본 원단위는 공동주택의 도면을 실측 분석하여 원단위를 산정한 후 시뮬레이션을 실시하여 회귀분석 모형을 개발하였다. 또한 이의 활용성을 높이기 위해 전산시스템을 개발하였다. 본 모형의 적절성을 파악하기 위해 사례분석을 실시하였다. 본 회귀모형은 공동주택의 바닥면적 및 세대수를 근거로 22개 폐기물을 비교적 쉽게 산출할 수 있는 장점을 갖고 있다. 본 모형은 국내에서 광범위하게 이루어지고 있는 재개발, 재건축 등에서 발생 가능한 폐기물을 정확하고 쉽게 산출할 수 있는 장점을 갖고 있는 것으로 파악되었다. 해체물량의 정확한 산정과 예측은 건설폐기물관리에 많은 도움을 줄 수 있을 것으로 기대한다.

급속한 경제성장과 더불어 복지 및 생활여건의 개선에 따라 재개발 $\cdot$ 재건축이 크게 증가하고 있으며, 또한 변화하는 사회 환경에 맞추어 건설공사의 규모 또한 점차 대형화 되어가고 있는 추세이다. 따라서 이러한 재개발 재건축 등의 활성화로 인하여 도심지 해체공사가 증가함에 따라 건설폐기물의 발생량이 대폭 증가하고 있다. 따라서 건설폐기물의 적정관리는 매우 중요한 사항이 되어 가고 있으나, 발생 폐기물을 정확히 예측하기 위한 연구가 부족하였다. 따라서 본 연구에서는 공통주택의 해체물량을 정확히 예측학 수 있는 건설폐기물 원단위 산정 기준을 제시한다. 이것은 해체공사 시 발생 가능한 건설폐기물을 손쉽고 정확히 예측할 수 있으며, 이것은 국가 폐기물 정책에 매우 중요한 자료로 활용될 수 있을 것이다.

The purpose of this study was to contribute to planning and developing various new apartment unit plans of the future through examining the differences on the spatial behavioral patterns and the post-occupancy evaluation between DK-front type and DK-rear type. 245 households which were included 79 DK-front types and 166 DK-rear types, were collected and analyzed at Masan and Gimhae cities in Kyungnam area. The result is as follows: 1) The analysis of the spatial behavioral patterns revealed that Anbang was the room for the couple independent from guests and children. Living room was the family's room for every activity, used more frequently DK-front types than DK-rear types. The family lift cycles of households, the visual unification between Living room and DK, the closed figures of DK in DK-front types have been influenced for the activities of Living room. 2) In the post-occupancy evaluation, DK-front types were positive in the lighting of DK area and its connection with Living room, while negative in the proximity from entrance to DK, cooking convenience, and the proximity between rooms. It was explained clearly through the reasons of the rejection of DK-front types from now.
