Soil is potentially suitale alternatives for use in many environments because many of the conventional materials have been encountered to be shortage due to excessive use by human. However soil without any modifications has been found to be unsuitable for building construction materials. Soil with reinforcement are naturally an answer to these alternatives. Through recent studies about fiber mixed soil, it has been shown that. fiber is a good material to be applied to the building wall. In this study, engineering properties of fiber mixed soil are collectively shown and ideas about use of fiber mixed soil are proposed in addition to the use for building wall,.

As Construction and Demolition (C&D) debris increases every year, systems have been adopted to compel the use of recycled aggregate made from C&D debris, and the use of recycled aggregate in the construction field has increased. But environmental problems linked to the alkalinity of recycled aggregate have occurred, and a study on approaches to lower the alkalinity of recycled aggregate is needed. It was certified by this study that a large amount of recycled aggregate could be carbonated in the C&D debris midterm-treatment field. As a result, the density and the water absorption of recycled aggregate after carbonation reaction was improved, and pH of recycled aggregate was lowered from over 11 to 9.4. X-ray Diffraction (XRD), Scanning Electron Microscope (SEM), Energy Dispersive Spectroscopy (EDS), and Thermogravimetry/Differential Thermal Analysis (TG/DTA) methods also indicated the carbonation of recycled aggregate.

In this study multi-zone modeling program CONTAM 2.4 which is developed by NIST is used for modeling the air disinfection system which is consist of dilution, filtration, ultra violet germicidal irradiation (UVGI) for removing the indoor microorganism such as bacteria and fungus. Developed models those protect occupants against indoor microorganism generated in our daily life are enable to use for immune building simulation tool. Also, results indicate that those models are enable to compute the real situation that is almost impossible of carrying out experiment and identify the disinfection rate with highly reliance. Results also suggest that engineers will use these models as a design tool for the immune building system.

Nowadays, a source of all water, which has been spent by a lot of people, is the rainwater The rainwater is directly relating human being' life. According to how to use rainwater. human being' life is abundant or poor. Due to the lack of underground filtration quantity, the water circulation of the city is discontinued and the underground ecosystem is destroyed. This study suggest that the unused underground space of building and temporary structure can be used into rainwater storage tank in the facility to use rainwater. Moreover, in this study, while the building is constructed, It is showed that the water used in construction can be replaced in the rainwater.

The issue of sustainability has been prevailed not only in building industry but also all other industries. It has been raised that the concept of sustainability should take into account for the design of multi-use high-rise apartments. In this study, the present situation and trends of the multi-use high-rise apartment construction have been reviewed. The definition of sustainable design of high-rise apartment has been clarified so as to perceive the related design elements through the literature survey. Finally this study has derived the sustainable design elements of high-rise apartment unit plans through the comparative analysis of sustainable design guidelines, environmentally friendly building accreditation systems and literature survey in and abroad.

Apartment houses maintenance like remodeling in at issue and the importance is getting higher. On this study, we analyzed a variety of the influence factor affected building's maintenance expenses. circumstance influence factor about maintenance expenses is classified into region(big city, small and medium city), (area of high snowfall), (downpour region), (earthquake region), location(waterfront, inland province), using condition(mixed use, single use), frequency of use(kindergarten, middle school, high school), architecture method(reconstruction, construction).

Tall building has some controversial aspects with low carbon city, but it is still a sensible choice for the metropolitan city. This paper aims to develop holistic urban design strategies to minimize impacts on the environment, increase energy efficiency and improve the quality of living in tall building communities by utilizing tall building characteristics. It puts forward the concept of integrated tall building-low carbon community design from the perspective of urban design, and summarizes five core strategies: Temporal state based on energy use, Complementary energy use state based on functions, Spatial state based on regional environment features, Transportation state based on low-carbon lifestyle and Waste utilization state based on tall building characteristics. It also applies the strategies to a practical project. The results show that the proposed urban design strategies are available approaches to mitigate the side effects of tall building on low carbon city.

Indoor air quality (IAQ) is recognized as a byproduct of industrialization that took place in the 20th century. The great attention to IAQ has been gained since 1980s, and led to numerous research studies that have mainly made in the developed countries. As the development of residential environment in Korea enters in the process of qualitative growth, IAQ has viewed as one of the core issues in the society, and research in relation to IAQ has been implemented until now in the fields of engineering and medical science. It is widely known that the sources and effects of indoor air pollution have been various, and IAQ research with multidisciplinary approaches is required. Nevertheless, few research embedded into a socio-behavioral approach to identifying interventive measures of residents and analyzing their choices is made. The purpose of this study is to examine the use of an interactive measure of residents in apartments that is air purification with phytoncide available in the market, and to investigate their self-reported effects of the air purifying substance on sick building syndrome symptoms. This study utilizes a field experiment design with pre-test and post-test, and the experiment is conducted in a natural field setting. A total of 87 test subjects from 32 households with already sick building syndrome are drawn via internet, and the participation is solely voluntary. The participants receive and use the air purifying substance, and are asked to use it continuously for two weeks and identify their self-reported symptoms of before- and after-use. The research findings indicate that air purification using phytoncide is effective to alleviate their symptoms in relation to sick building syndrome. Also it is noted that the participants report that the use of the air purification causes the positive impacts on their daily life. Further research is needed that compares the group with only humidifier and evaluates the mid-term and long-term use of the air purification and its effects.

30년 이상 된 노후 건축물의 비율은 2005년 29.0%에서 2019년 37.8%로 증가하였다. 이러한 노후 건축물은 화재 안전 성능 등 건축 관련 안전기준이 부재했던 시기에 조성된 건축물이다. 사용 과정에서 불법적인 변경과 증축이 이뤄져 안전에 더욱 취약해졌을 것으로 예상된다. 다중이용건축물 등 대형재난을 막기 위해 소방 안전 조사가 이뤄지고 있지만 대규모 노후 건축물이 밀집한 지역구 차원에서는 조사가 이뤄지지 않고 있다. 따라서 노후 건축물이 밀집한 노후 건축지구에서 화재 위험 요인을 도출하기 위해 우선 건축물의 구성 특성을 분석하였다. 화재 위험 요소 도출을 위한 노후 건축지구의 공간적 특성을 살펴보기 위하여 건축물 구조, 용도, 지붕형태, 사용승인연도를 기준으로 분석한 결과, 건축물 사용승인일을 기준으로 건축물의 주구조가 가장 큰 영향이 있었으며, 건축물 주구조를 기준으로 주거환경개선지구의 경우 지붕형태, 그 외 지역은 건축물의 주구조가 가장 큰 영향이 있는 것으로 나타났다.
