  • 본 연구에서는 국내에서 가장 일반적인 유형의 주택으로서 3인 가구가 거주하는 공급면적 $117.69m^2$의 일반형 아파트를 측정 주택으로 선정하여 실증 측정을 진행하였다. 황사 발생이 포함된 3일 측정기간 동안 미세먼지 변화 특성을 관찰하여 분석하였다. 관측된 미세먼지($PM_{10}$)를 상대적으로 큰 먼지($PM_{10-2.5}$)와 초미세먼지($PM_{2.5}$)로 나누어 대기와 실내의 먼지의 농도변화를 분석하였다. 연구 결과로 재실자의 활동이 없는 외출이나 취침 기간에는 주택의 침기 특성을 확인할 수 있었다. 미세먼지 중 상대적으로 큰 $PM_{10-2.5}$ 크기 입자는 외기의 풍속이 5 m/s까지 증가하여 침기량이 증가해도 대기 농도 대비 실내 농도비가 7% 이하인 반면, $PM_{2.5}$의 경우 외기 속도가 5 m/s까지 증가하면 50% 이상으로 증가하였다. 황사가 심한 대기 상태에도 본 연구의 측정 주택의 경우 실내 $PM_{10-2.5}$는 시평균$15{\mu}g/m^3$로 대기 농도의 5% 수준으로 일상 조건과 비슷했다. 재실자의 활동이 있는 경우에는 미세먼지 중 초미세먼지를 제외한 상대적으로 큰 먼지는 자연환기와 실내 사람의 움직임과 같은 행동 영향이 지배적이었다. 실내 $PM_{10-2.5}$ 농도는 대기 농도가 낮은 경우에는 대기 농도의 약 50%를 차지하는 경우도 있었다. 재실자의 활동 중, 초미세먼지의 발생이 클 것으로 예상되는 굽기나 튀기기가 포함된 조리나 실내 흡연이 없었기 때문에, 재실자가 없는 경우와 마찬가지로 초미세먼지는 실내 농도가 실외 농도의 추이에 따라 함께 변동하는 양상을 보였다. 외부공기가 침기에 의해 창틈, 문틈으로 유입되는 과정에서 초미세먼지는 약 30~40% 정도가 제거되고 실내로 많은 비율이 유입되기 때문에 실외 초미세먼지의 실내에 대한 영향이 컸다. 본 연구의 분석 데이터는 측정이 이루어진 대표 주택에 해당하는 것으로, 새로 지어진 기밀 성능이 높은 신축 아파트나 침기가 상대적으로 클 것으로 예상되는 오래된 단독주택에서는 다른 특성이 나타날 것으로 예상되므로, 이에 대한 추가적인 연구가 필요하다고 생각된다.

  • It has applied the design method of face to face dimension, an MC (Modular Coordination) design method, at design steps of an apartment house for standardization of architecture. But It has been still using center line size. A construction limit isn't specific on these center line size, and dead space occurs with excessive gaps as size matching isn't performed well between structural sieve and parts. And above all, measurement before construction isn't to expect standardization, and to increase custom-made furniture. We investigate manufacture of a preferential domestic system kitchen and construction state, and we derive from a problem in viewpoints of standardization for this. And we utilized a reference plane, and we present construction document and design plan in order to solve these problems. And we analyze an effect got by application of the assembly basis aspect that we presented, and we can raise efficiency of standardization of housing and construction industry, and we light ultimately up.

  • 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.

  • Today, our lifestyle and residential culture has been changed have been changed by interchange with various countries in various sides. In order to become an internationally recognized residential environment designer in this environment, we must understand the housing viewpoint of residents in a country first. Therefore, this study was intended to obtain useful material for residential environment design of both countries by comparing the housing viewpoint between Chinese students studying in Korea and Korean students. A questionnaire was conducted on 205 Korean students and 193 Chinese students (Korean race) from Y University in random sampling basis. The result is as follows. First, both Korea and China have a higher ratio of apartments in both current and previous types of house. But, both Korea and China have similar ratios between detached house and apartment for a desired type of house at the time of moving in. Second, Korean and Chinese university students consider and as the most important functions of residence, and Chinese university students consider more functions of residence than Korean students. Third, both Korean and Chinese consider a living room as the most important space among housing spaces, but Chinese consider a private room more importantly than Korean. Fourth, overall satisfaction rate of Korean students for current houses was average, and most Chinese students were generally satisfied with their houses.

  • The new apartments has been rapidly built through the outskirts of Cheong-ju city since the latter half of 1980's. So, the population decreased in Seong-an dong and Jung-ang dong which are located in traditional urban area of Cheong-ju. Also, residential areas became obsolete and residential buildings happened to be vacant and empty. For urban rehabilitation, the city authorities will construct the high-rise complex housings with stores in the traditional urban area. We have doubts about whether the rapid change of new housing construction is right or not. Therefore, It is necessary to give a correct diagnosis of the present state from urban atrophy, keeping this area sustainable with traditionality and locality. This study is to examine and analysis in detail distribution patterns and habitable floor area by house types in Seong-an dong and Jung-ang dong which are located in traditional urban area of Cheong-ju. The result are as follows; the residential buildings as the 2,680 houses(including detached and apartment houses) and the 804 shop houses are distributed with 3,484(67%) of the whole 5,183 buildings and form 28percent of the whole floor areas. A distribution and area ratio of houses to shop houses is irrespectively about 76 : 24percent. The average floor area is represented with $66m^2$/household and $28.5m^2$/person. It shows that a hollowing out of urban area has caused the surplus of residential buildings and floor areas.

  • Indoor air quality can be affected by indoor sources, ventilation, decay and outdoor levels. Although technologies exist to measure these factors, direct measurements are often difficult. The purpose of this study was to develop an alternative method to characterize indoor environmental factors by multiple indoor and outdoor measurements. Using a mass balance model and regression analysis, penetration factor (ventilation rate divided by the sum of ventilation rate and deposition constant) and source strength factor (source strength divided by the sum of ventilation rate and deposition constant) were calculated using multiple indoor and outdoor measurements. Subsequently, the ventilation rate and $NO_2$ generation rate were estimated. Mean of ventilation rate was 1.41 ACH in houses, assuming a residential N02 deposition constant of 0.94 $hr^{-1}$. Mean generation rate of $NO_2$ was 16.5 ppbv/hr. According to house characterization, inside smoking and family number were higher $NO_2$ generation rates, and apartment was higher than single-family house. In conclusion, indoor environmental factors were effectively characterized by this method using multiple indoor and outdoor measurements.

  • In this study, a dwelling type of Korea and Japan was compared, and consumption rate of domestic timber and its usage was also investigated. In Korea, dwelling type of apartment which constructed by iron and steel-concrete is main shared, but a detached house which is shared at 60% of dwelling type of Japan is mainly constructed by timber. And the rate of the consumption of domestic wood in Japan is 73%. In Japan, there is an effort to substitute imported wood to domestic timber through the promotion of using of domestic timber. Whereas the needs on using of domestic timber gradually emerged. So, the legal about sustainable use of wood is approved by the National Assembly on May 2012. There is not active movement in the aspect of using of domestic timber yet. These causes to the geographical and environmental characteristics, but industry, policy, and the difference of recognize on domestic timber utilization is thought to do greater influence. Hence, it is recommended to make a portfolio of both balanced domestic timber usage and the change of awareness of people by referring to the example of Japan.

  • In the energy consumption of buildings in Korea, the housing sector accounts for 53% of a total energy consumption. Although the researches of energy consumption on the new detached houses and apartment houses have been conducted numerous times, the researches of energy consumption characteristics on the existing detached houses are lack of studies. Thus in this study, the actual condition of energy consumption characteristics on the existing detached houses in Daegu city was examined, and then energy consumption unit and green house gas emission unit was compiled to present a fundamental data for an effective way of reducing energy consumption and greenhouse gas emission in the buildings. The results showed that the energy consumption for heating in the existing detached house was greater than other energy consumption and the heating energy sources were city gas and fuel oil. As the fuel oil consumption got larger, the energy consumption unit and greenhouse gas emission unit became bigger. Based on these results, it will be able to develop a plan for reducing energy and greenhouse gas emission in the existing detached houses in the future.
