This paper analyses the structure of integrated design of sustainable architecture and proposes improvement of it. Existing Integrated design process(IDP) have some pitfalls of rigid process and fragmentation of each elements. The cognition of ecological system composed of built and fluid environments and inter-relationship between them (environmental indexes) sheds lights on improvements of integrated design. Projects get a wide-range of targets from it and the structural frame of them can be established in detail in order to decide the level and methodology of integration. Taking the whole structure in mind, the process of integration design can be settled. 1) During planning step, overall strategy is developed with the guidance of environmental indexes and design team is set up. 2) During schematic design , integration level and alternatives are developed through design workshops with many verification tools(a feedback design). 3) During design development, the performance of integration systems are optimized with material selection, occupants pattern and seasonal operation schedule. Several design tools have been developed, but their specific target cannot cover a whole integrated design process, so the optimized integration of tools should be investigated as well.

본 논문에서는 안료 첨가량 및 폴리머-결합재비가 칼라 폴리머 시멘트 모르타르의 물성에 미치는 영향에 대해 실험적인 분석을 수행하였다. 주요 평가항목으로는 강도특성, 염화물이온침투저항성, 중성화 저항성, 투수성, 길이변화 및 동결융해저항성 등으로 설정하여 실험을 수행하였다. 실험 결과, 폴리머-결합재 비가 증가함에 따라 칼라 폴리머 시멘트 모르타르의 압축강도, 휨강도, 인장강도 및 부착강도가 증가하는 경향을 보였으며, 투수성, 길이변화, 염화물 이온 침투 등은 감소하는 경향을 보였다. 반면에 안료의 첨가량이 증가함에 따라 칼라 폴리머 시멘트 모르타르의 길이변화 및 강도 등의 역학적 특성과 중성화및 동결융해저항성 등의 내구성은 다소 저하하는 것으로 나타났다. In this study, the effect of the amount of pigment and polymer-binder ratio on the properties of color polymer cement mortar was experimentally investigated. The evaluation factors of experiment were the strength characteristics, chloride ion penetration resistance, carbonation, permeability, length change, and freezing and thawing resistance. As a result, the compressive, flexural, tensile, and bond strength of color polymer cement mortar tended to increase with increasing polymer-binder ratio, and the permeability, length change and chloride ion penetration tended to decrease. As the amount of pigment increased, however, mechanical properties such as strength and length change and durability such as carbonation and freezing and thawing resistance of color polymer cement mortar slightly decreased.

The purpose of this paper is to investigate energy saving and comfort enhancement potentials of a envelope performance improvement and natural ventilation in Korean Traditional Houses. User’s preference to detached house increased recently and comfort and low-energy consumption are the core requirement, so the strategies for both environmental performance should be researched. At first, this paper simulate energy consumption in three envelope performance levels in a typical linear shape house found that the proportion of cooling energy demand is sharply increased in a well-insulated and air-tight envelope and the cooling energy demand could be reduced by natural ventilation. The comparative analysis of energy balance in three types of Hanok shows that linear type recorded the lowest heating energy consumption thanks to the highest solar insolation and it resulted in the highest cooling energy consumption in spite of the largest natural ventilation potential. The enclosed type recorded the lowest natural ventilation potential and the slightly higher cooling energy consumption compared to the semi-enclosed type one. The air change rate in the living room was above 5 ACH and shows the cooling potential in linear and semi-enclosed type Hanok. PMV in all types of Hanok shows the improvement during cooling season. The whole integrated passive cooling strategies including natural ventilation should be researched in the future.

In order to investigate devolatilization characteristics for ashless coal with relatively low ash content and high heating value, an experiment was performed in different bed configurations of TGA and DTF(Drop Tube Furnace) at atmospheric pressure condition. The heating rate was 10℃/min up to 950℃ in TGA, while temperatures varied from 500 to 1300℃ in DTF. A weight loss and particle temperature were obtained to be used for kinetic analysis of the devolatilization. The kinetic parameters including an activation energy and pre-exponential factor for ashless coal were obtained using Coats-Redfern method in TGA and single step method in DTF. Furthermore, the devolatilization kinetics of the ashless coal were compared with the results of different kinds of conventional coal such as sub-bituminous and bituminous.

지역별 단독주택 에너지 절감 리모델링 전략 민감도 분석

이병연(Byungyun Lee),CHEN HAICHAO 한국산학기술학회 2020 한국산학기술학회논문지 Vol.21 No.9

그린 리모델링 전략 수립이 기술 중심적으로 진행되어 현장 상황을 반영한 맞춤형 전략 수립의 필요성이 제기된다. 본 논문은 리모델링 활성화를 위하여 현장에 적합한 리모델링 전략수립 방법론으로 민감도 분석을 통한 기술전략평가와 활용가능성 분석을 목적으로 한다. 30평형 규모 단독주택을 대상으로 에너지플러스엔진과 모드프론티어 최적화기법을 통합하여 활용하여 서울, 대전, 부산지역에 1980년대 이전, 1984년, 2010년 준공기준을 적용한 총 9개 모델대상 최적화 후 민감도 분석을 통한 리모델링 전략 우선순위를 도출하였다. 1980년 이전 모델의 경우 지붕 단열성능강화 전략이 민감도 상위 순위를 갖는 것으로 나타났다. 창호 총일사취득율 기준은 전 지역, 전 준공 시기를 막론하고 다음 상위 민감도를 갖으며, 이는 열관류율 중심 기준에서 총일사취득율 기준을 포함하는 성능 기준으로 확대될 필요가 있음을 보여준다. 대규모 철거공사를 수반하는 창면적비의 조정은 민감도가 낮아 형상 유지 리모델링의 효용을 확인하였다. 사례별 상이한 민감도 결과는 리모델링 전략 수립에서 민감도 분석을 경제성, 시공성 등의 기준 등과 함께 종합적인 리모델링 전략 수립의 가능성을 제시한다. The establishment of a green remodeling strategy is focused on technology, so the necessity of establishing a customized strategy considering the field situation has emerged. This paper examined the technology strategy through sensitivity analysis as a methodology for guiding strategy. For a 90-square-meter detached house, nine models of the construction standards of pre-1980s, 1984, and 2010 in Seoul, Daejeon, and Busan were assessed using the optimization method that combines the energy plus engine and the ModeFrontier. Sensitivity analysis was performed, and the remodeling strategy priority was derived. For pre-1980 models, the strategy for enhancing the roof insulation performance had a significant priority. The SHGC values of the windows were found to have the next highest priority regardless of the region and the time of completion, showing that the performance standard, including the SHGC, needs to be expanded. The possibility of remodeling while maintaining the existing geometry was confirmed because the adjustment of the window wall ratio accompanying large-scale demolition works has low priority. The priorities of technology strategies in each case showed very different patterns, suggesting the possibility of establishing a remodeling strategy by a comprehensive evaluation along with economics and constructability analysis.
