A Study on the Characteristics of Construction Wastes Generated from Demolition of Buildings in the Housing Environment Amelioration District

손병훈,홍원화 대한건축학회 2013 Architectural research Vol.15 No.1

The amount of construction waste increased to 176,447 ton/day in 2008 from 28,400 ton/day in 2000,.a 6-fold increase in just 10 years. Such dramatic increase in the waste of concrete, asphalt concrete, wood and metals was due to demolition of old buildings as well as a great number of building redevelopment projects and hurried city industrialization. Many buildings targeted for demolition today were built in line with the government policy to provide affordable housing to citizens in the shortest time possible and consequently, said buildings underwent rapid deterioration and required periodic repairs and reconstruction. Based on the above, we predict that construction waste will continue to increase for the foreseeable future. In particular, due to limited availability of suitable space to construct apartments and residential buildings in the city, old buildings are being torn down to make space for new development, further increasing construction waste. In light of that, efforts to recycle as well as reduce generated waste are urgently required.

Today, many industrialized nations are limiting development that are harmful to society as da whole and are formulating policies to counter the environmental problems. Korea in following such trend, began discussion to reduce the greenhouse gas emissions to 5% below 1990 levels by 2008-2012, as the Kyoto protocol became a legally binding treaty on 16, February 2005.In Korea, it has constructed many apartments and buildings since 1960's~1970's. Recently reconstruction of buildings increases to reform housing condition. About 300,000 ton of construction waste is produced everyday in domestic construction site. Occurrence amount is increasing continuously. Construction waste has little harmfulness, and it could be used as circulation aggregate after proper treatment. However, recycling rate is very low due to current work process and the cost involved in the recycljng.Accordingly, in this study, we will offer basic data for other measurements on the occurrence of construction waste by types and processing method when demolishing buildings.

화재 위험요소의 도출을 위한 노후건축지구의 공간구성 특성분석

손병훈,강경하,류정림,노승준 한국건축시공학회 2022 한국건축시공학회지 Vol.22 No.1

The proportion of buildings over 30 years old in Korea has increased, from 29.0% in 2005 to 37.8% in2019. These old buildings were built during a time in which there was a lack of building-related safetystandards in areas such as fire safety performance. Worse, during their years of use, many such oldbuildings have had illegal changes and extensions made, making them more vulnerable in terms ofsafety. Fire safety investigations are being conducted to prevent large-scale disasters in multi-usebuildings, but no investigation has been conducted at the regional district level, where small-scale oldbuildings are concentrated. Therefore, to identify fire risk factors in the old building district where oldbuildings are concentrated, the composition characteristics of the buildings were first analyzed. Toexamine the spatial characteristics of old building districts in order to derive fire risk factors, theresults of this analysis based on the structure, use, roof type, and year of approval for use are as follows. It was found through our analysis that as of the date of approval for the use of the building, the mainstructure of the building has the greatest impact. 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 노후건축물이 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.

The number of old buildings older than 30 years in Korea continues to increase from 29.9% in 2005 to 38.8% in 2020. Considering the growing urban regeneration projects, urban maintenance projects, the suppression of urban expansion, and the lack of idle land in the city, the dismantling of old buildings is expected to increase further in the future. As major accidents at building dismantling sites continue to occur, related agencies are also strengthening safety management of building dismantling works. While physical safety management such as collapse and fall is strengthened, there is a relative lack of interest in the health of workers at dismantling sites due to environmental hazards. Since relevant laws stipulate that construction waste should be separated and discharged, old buildings need to be considered for environmental hazards such as fine dust, floating bacteria, and floating molds when dismantling. In this study, we intend to find important safety management elements in the management of building dismantling sites, measure environmental factors harmful to dismantling workers, and present basic data for the management of dismantling sites in the future. "Safety management" was the highest priority, followed by "dust," "vibration," "noise," "bacteria," and "smell." The perception of the importance of "physical damage prevention" with workers working on dismantling and managers managing the site came out similar, but the perception of "work efficiency" and "health disorder prevention" through environmental hazard management showed different priorities. In the process of dismantling, floating bacteria and floating mold were collected, cultured, and measured the concentration in the indoor air. The measurement was measured by dividing it into pre-dismantling and during dismantling.

Review: Condensation and Evaporation Characteristics of Low GWP Refrigerants in Plate Heat Exchangers

손병훈,전승원,Yong-Chan Kim,Yong Tae Kang 대한설비공학회 2016 International Journal of Air-Conditioning and Refr Vol.24 No.2

In this paper, condensation and evaporation characteristics of low global warming potential (GWP) refrigerants such as R-1234yf and R-1234ze series are reviewed. This review focuses on heat transfer and pressure drop in plate heat exchangers. Mass flux is considered as an important factor while saturation temperature is not for condensation and evaporation process in plate heat exchangers. The dryout phenomenon occurs occasionally and gives greatly harmful impact on evaporation heat transfer. It is found that R-1234yf and R-1234ze(E) give slightly lower heat transfer performance than R-134a for both condensation and evaporation processes. Generally, low GWP refrigerants presented in this review give lower heat transfer coefficient and higher frictional pressure drop than the conventional refrigerants. Nevertheless, R-1234ze(Z) gives superior heat transfer performance than other refrigerants in condensation. R-32 gives remarkable performance in evaporation, but it gives relatively high GWP compared to other low GWP refrigerants.

The proportion of old buildings over 30 years old increased from 29.0% in 2005 to 37.8% in 2019. These old buildings were created during the absence of building-related safety standards such as fire safety performance. In the process of use, illegal changes and extensions were made, making them more vulnerable to safety. In the 1st Basic Plan for Fire Safety Policy, among the 12-Key Tasks, one is to ensure the safety of residential living spaces. Fire safety investigations are being conducted to prevent large-scale disasters such as multi-use buildings, but no investigation has been conducted at the regional district level where small-scale old buildings are concentrated. Therefore, in order to derive fire risk factors in the old building district where old buildings are concentrated, the composition characteristics of the buildings were first analyzed.
