Recently, new detached houses on a small plot in low-rise residential urban area have attracted more public interests than ever before. This study aims to categorize basic types of interior plans in small urban detached houses by analyzing the layouts of the public space(LDK) within them which are popular in Japan. The results of this study may be summarized as follows. Unit floor plans were basically classified as 16 types according to the layout of LDK. Among these, the LDK type in a straight line shows the most at 28.9%. Again, these plans were sub-classified into 38 types by plan composition. The new 'LDKL' (a new term the authors propose to be used) type was observed in cases where K was directly connected to L. This type appears at 9 out of 38 types. In the connection of LDK, the LDK type shows the most at 60.8%; secondly the L-DK type at 29.9%; thereafter the LD-K type at 6.2%; and lastly L-D-K type, the least frequently at 1.0%. The cases of inter-level connection between LDK and the surrounding space were observed in various cases such as the open workplace of the upstairs hallway visually connected with LDK through the void space and as the attic space of the pitched roof visually linked to it.

The purpose of this study was to measure the indoor air quality of small-scale apartments and then proposed a method to improve the indoor air quality of the small-scale apartments by comparing with the result of indoor air quality in the Clean-Healthy House. In case of formaldehyde, a highly volatile organic compound, the concentrations of indoor measured both in small-scale apartments and the Clean Healthy houses did not exceed- the guideline of Korea. The guideline of Korea for acetaldehyde was not available, so the guidelines of Japan and the World Health Organization were used to measure the concentration of acetaldehyde. The study results demonstrated that three out of seven small-scale apartments investigated exceeded the guideline of Japan; and the preliminary research on the Clean-Health Houses was low at about 30-60% of the guideline of Japan. The result of the VOCs measurement showed that toluene, ethylbenzene, and styrene in some small-scale apartments exceeded the guideline of Korea. However, the Clean-Healthy Houses in the previous studies did not exceed the guideline of Korea with regard to all the pollutants. Therefore, this study suggests the application of the construction standards of the Clean-Healthy house in order to improve the indoor air quality of small-scale apartments. In addition, the current study anticipates that improvement of the indoor air quality in the residential environments should be universally applied, not limited to the type and size of the residence.

소형주택은 2009년 완화된 주택법 이후 꾸준히 공급되어져 오고 있다. 이에 본 연구는 소형주택 시공 관련 전문가 집단을 대상으로 설문조사를 실시하여 문제점을 도출하여 개선방안을 제시하고자 하였다. 첫째, 저가수주는 불리한 계약의 주요 원인이며 수주실적관리를 위해 저가수주를 하고 있었다. 저가입찰 및 저가수주는 건설 업체 유지를 위해 계약하게 되고 결국 건축물 안전 환경까지 위협하게 되는 것이다. 또한 적절한 기간의 입찰 및 공사 기간이 주어져야 할 것으로 판단된다. 둘째, 시공 프로세스를 준수하지 못한 사례가 많아, 중소건설업체의 업무 표준화가 필요한 상황이며, 관련 내용을 인지하지 못한 실무자가 많아 정기적인 교육이 필요한 것으로 판단된다. 셋째, 현재 가장 필요한 정책 방향에 대해 저가입찰 지양과 부실업체 시장퇴출이 가장 높게 나타났다. 안전 환경을 위해 저가입찰과 부실업체에 대한 개선이 필요하다고 판단된다. 대부분 소형주택을 짓는 중소건설업체는 업무 여건이 열악하다. 따라서 업무에 대한 표준화와 저가수주 지양으로 소형주택의 안전 환경을 제고해야 할 것이다.

1970년대 이후부터 이룩한 경제성장은 심각한 도시화 현상을 초래하였으며, 인구 증가와 함께 심각한 주택부족 현상을 가져왔다. 이에 정부를 비롯한 민간 건설업체는 도시지역의 주택수요를 충족시키기 위해 아파트를 비롯한 공동주택을 꾸준히 건설하게 되었다. 아파트는 주로 철근콘크리트로 건축되며, 처음에 가졌던 성능을 유지하기 어렵고, 지속적인 노후화 및 주거생활 문화의 변화에 따라 리모델링을 실시하게 된다. 리모델링은 환경문제 및 자원절약이라는 측면에서 재건축 보다 효율적인 방법이기 때문에 건축분야의 커다란 콘텐츠로 자리매김하게 되었다. 그러나, 아파트의 리모델링 공사는 필요에 따라 소규모로 이루어지고 있어 리모델링 공사에 대한 정보가 부족한 실정이며, 특히, 리모델링 공사 후에 발생하는 하자에 대한 정보는 더욱 부족한 실정이다. 따라서 본 논문에서는 아파트 리모델링 공사 후에 발생하는 하자의 발생시기와 원인에 대하여 설문조사를 실시한 후 결과를 분석함으로써, 아파트 리모델링 공사에 대한 정보를 제공함과 동시에 향후 아파트를 비롯한 공동주택의 효과적인 유지관리를 위한 기초적인 데이터를 제시하고자 한다.

This case study is an effort to provide new knowledge on the U.S. elderly public housing focusing on the residents' perceptions of the environmental conditions. For this study, we conducted a survey using written questionnaires and interviews with 20 residents who rent in Columbia, MO. The recorded interview data was used for final analysis; primary findings are as follows: The residents reported relatively high satisfaction on their overall environmental conditions in the two target public housing, built in 1950s. As the most significant problem, residents perceive the lack of storage space for individual units, Partially attributed to space limitations. In addition, bathroom needs varied dramatically among residents based on their health and whether wheelchairs are used. Therefore, it was found that instead of standardized bathrooms, a customizable configuration for the resident's unique physical condition and accessibility must be considered. The residents also addressed their concerns about security for entrance and foyer areas. Due to the small living areas, they wanted to have available outdoor public space for various social activities. Furthermore, they reported the need for small social gathering areas while friends and family members are visiting them, in addition to their small living units, which average 49.8 sq. ft. each.

This study examined the building envelope structure used in small housings near urban area which have not good energy source in relation to the application of passive design for energy saving of small-sized architectural design firms in local cities and aimed to provide the basic materials of future design direction of designers and housing owners by analyzing economy of a project in order to know the amount of energy saving and additional expenses depending on the building envelope pattern. As a result of comparing and examining the energy saving cost from the period of use compared to investment by the thickness of insulating materials based on building envelope pattern for energy saving, it was found that the thicker the insulating materials are, the more energy saving amount is. While the current bead-type insulating materials have short payback period due to low initial investment, extruded insulating materials show the difference of five years compared to bead-type insulation because of its high initial investment.

As the urban regeneration project and the old housing maintenance project are actively progressing in Korea, small-scale building construction is being carried out in downtown areas. Small buildings in the downtown area are constructed on about 4 to 10 floors, and since they are carried out in small units in residential areas, it is difficult to enter large equipment to construct existing piles, and it is more vulnerable to complaints about noise and vibration. in this study, helical piles suitable for urban areas or small sites where it is difficult to enter large equipment, such as noise and vibration. Reliability analysis was performed on the results of the static load tests and dynamic load tests conducted at the LH site and the bearing capacity calculated by the hydrostatic method and the empirical formula (N value). As a result of comparing and analyzing the design formula and the results of static load test and dynamic load tests, the correlation between the design formula of the bored pile (Road bridge design standard) formula using N value and the design formula by the modified Davisson method frequently used by method commonly European helical file practitioners.

This study examines the distributions of daylight illuminance in a small office space under clear and cloudy sky conditions. Three shading conditions using Venetian blinds were applied for the analysis of daylight illuminance. Computer simulations using the Lightscacpe were conducted for the daylight conditions applied to the office space. Results indicate that the illuminance differences between clear and cloudy sky for south-facing conditions were greater than those for north-facing conditions. The differences in December and June were the greatest and smallest, respectively. For the north-facing conditions, the daylight illuminance at 10:00, 12:00 and 14:00 in June and September under the cloudy sky was higher than those under the clear sky conditions. For all daylight conditions, the biggest amount of illuminance reduction occurred when the shading device conditions were changed from the no blind to the 45 degree blinds. As the distance from window increased, the shading effect that occurred when the shading device conditions were changed from the horizontal blind to the 45 degree blinds increased.
