There is some recognition that Decoration Wood-based Flooring Board in Korea is a material that inhibits the heat transfer from the substrate to the room. There is a lack of substantial research literature on the surface heat transfer and condition of Decoration Wood-based Flooring Board, which is insufficient to deal with false perceptions. In this study, the purpose of this study is to analyze the surface heat transfer characteristics of Decoration Wood-based Flooring Board and to obtain basic data to cope with recognition.

The present study was to develop a dry PFB method similar to the existing gypsum board construction method in order to apply the existing wet PFB method that uses fire-resistant adhesive. It was found that the existing wet method can produce concrete compressive strength of 80MPa and fire resistance of 3 hours with 30mm PF boards. The goal of development in this study was fire resistance of 3 hours through dry construction of 15mm fire-resistant boards. 1. Improved PF board was prepared by adding inorganic fiber to existing board and using aggregate with grain size of 3mm or less. Molding was done at temperature higher than that for existing PF board molding. While wet curing is used for existing PF boards, this study used dry curing in order to enhance heat insulation performance. 2. According to the results of fire resistance test, when the dry PF method was applied, the temperature of the main reinforcing bar was 116℃ in 15mm, 103.8℃ in 20mm, and 94℃ in 25mm, and these results satisfied the current standards for fire resistance control presented by the Ministry of Land, Transport and Maritime Affairs. When a 3-hour fire resistance test was performed and the external properties of the specimen were examined, the outermost gypsum board hardly remained and internal PF board maintained its form without thermal strain.

최근 기후변화로 인해 전 세계적인 지구온난화 피해가 심각해지면서 주요원인인 온실가스에 대한 배출 규제가 확대되고 있다. 그 중 온실가스 배출량의 약 25%를 차지하는 건물분야에 대해 정부에서는 2020년까지 BAU 대비 26.9%까지 감축하겠다는 목표를 발표하였다. 이를 달성하기 위해 건물부문의 에너지 수요를 원천적으로 저감하는 녹색건축물 활성화 방안을 추진하고 있다. 하지만 녹색건축물 활성화의 상세 이행계획 수립 및 관리, 그리고 시행에 따른 효과를 분석하기 위해서는 건물 에너지 사용량에 대한 데이터 및 관련 통계 자료가 필수적이다. 이를 위해 정부는 전국 680만동의 건물에서 사용되는 에너지 정보를 통합 관리할 수 있는 국가 건물에너지 통합관리시스템을 구축하였다. 하지만 현재 구축된 국가 건물에너지 통합관리시스템의 Database는 건축물대장 정보와 공급기관의 에너지정보를 매칭해서 사용하기 때문에 수동으로 작업이 이루어지고 있으며, 이로 인해 많은 문제들이 발생한다. 따라서 Database의 신뢰성을 확보하기 위해서는 지속적인 고도화 작업이 이루어져야 한다. 본 과제는 현재 가동 중인 국가 건물에너지 통합관리시스템의 Database를 분석하여, 시스템의 한계 및 개선방안 도출하고, 이를 통해 데이터의 신뢰성 확보 및 활용성을 증대 시키고자 하였다. 구축된 Database 분석 결과 건축물 정보와 에너지정보가 매칭된 유효데이터는 평균 85.6%이고, 미매칭된 데이터는 평균 14.4%로 나타났다. 미매칭된 데이터는 다시 건물 특성에 따른 미매칭 유형을 분석하였으며, 그 결과 건축물 정보가 없는 경우가 전체의 58.2%에 달했다. 따라서 향후 신규 구축 data의 매칭 작업 용이성 및 현재 Database에 대한 정확성 확보하기 위해서는 건축물 정보와 에너지정보 간의 주소 표준화 및 속성정보 체계를 마련할 필요가 있다. 또한 비도시지역 및 영세한 주거지역에서 사용비중이 높은 석유류 에너지원 및 향후 발전 가능성 및 활용 가능성이 높은 신재생 에너지와 같이 다른 에너지원에 대한 정보를 포함시킬 수 있도록 시스템 구축이 필요할 것으로 사료된다.

In this study, as part of securing related data, water droplets were dropped on the upper part of the wooden board for flooring in an environment such as floor heating, and the degree of absorption according to the surface temperature change was tested. The test results showed that the contact angle of the surface was low (25℃→40℃) or the droplet was absorbed into the small plate and disappeared. The contact angle of the OSB and MDF was decreased within 30 minutes, but the surface water droplet was maintained longer than the plywood. This is because the surface is coated with hydrophobicity unlike the plywood, but moisture absorption in the cross section after the second processing will not be prevented and it will lead to defect occurrence problem.

In this study, fire resistance test according to KS F 2257-8: 2015 was carried out to compare fire resistance for wall consisted of gypsum boards with two types of drywall with gypsum boards which is based to lightweight studs. As a result, it was found that the fire resistance of the wall constructed with 12.5 mm of general gypsum board was 16 minutes higher than that of the wall constructed 9.5 mm in accordance with integrity and was 9 minutes higher than that of the wall(9.5 mm) depending on insulation. If the wall with the gypsum board 12.5 mm is constructed, it can be confirmed that the fire resistance is improved by about 43%.

Sick-building syndrome occurs when indoor air is polluted with harmful volatile organic compounds such as formaldehyde which are contained in furniture or new building materials. In this study, formaldehyde-shielding chitosangel sheet was developed and its performance was evaluated. Chitosan and agar were dissolved in acetic acid solution. The optimal concentrations of chitosan, acetic acid and agar were 3, 3, and 2.5 %(w/w). Formaldehyde was spreaded on gypsum board and then wall paper was attached on it by using glue. When chitosan-gel sheet was attached on this control board, the amount of formaldehyde released from the board was decreased by 63% than in control board. On the other hand, decrease in formaldehyde releasing was only 32% when liquid solution of chitosan was spreaded on the control board. This result clearly indicates that chitosan-gel sheet removes formaldehyde more effectively than liqud solution of chitosan. Furthermore, this type of sheet is more applicable to new building than spraying type.
