경제적인 측면이나 친환경적인 측면의 사유로 인해, 노후 건축물을 대상으로 그린리모델링 사업이 활발하게 진행되고 있다. 한편, 그린리모델링 사업을 추진하는 과정에서, 기존에는 설계자 및 엔지니어의 주관적 경험 및 지식에 기반하여 그린리모델링 계획이 개발되어 왔고, 이로 인해 경제성 등의 측면에서 효율적인 의사결정이 부족했다. 이에 본 연구에서는 노후 건축물의 속성을 분석하고 이에 따른 적정 리모델링 계획을 제안할 수 있는 온톨로지 기반 그린리모델링 의사결정 지원 모델을 구축하였다. 개발된 모델에서는 건축물의 기본 속성을 입력하면 온톨로지를 통한 웹검색을 기반으로 패시브 액티브 요소로 구성된 적정 리모델링 계획을 제공할 수 있다. 연구를 통해 개발된 결과물을 활용하면, 리모델링 사례의 증가에 따른 웹기반의 메타 데이터 검색을 통해 보다 객관적인 적정 리모델링 대안에 대한 의사결정 지원이 가능할 것으로 기대된다.

우리나라 정부에서는 저탄소 녹색성장 추진에 따라 기존 건축물의 그린리모델링 사업을 시행하고 있다. 하지만 그린리모델링 관련 현행 법규 및 제도에서는 그린리모델링의 범위와 그 내용을 명확하게 규정하고 있지 않다. 또한, 민간 참여를 위한 사업시행 유도책이 미비하여 민간의 그린리모델링 사업시행이 원활하지 않은 실정이다. 이에 본 연구에서는 실질적인 적용성을 고려한 그린 리모델링 사업시행 유도를 위한 조세혜택 부여 방안을 제시하였다. 또한, 제시한 대안을 2014년 그린리모델링 시범사업 사례에 적용하여 그 효과를 정량적으로 분석하였다. 이는 추후 그린리모델링 활성화를 위한 조세 감면혜택 제도 개선 연구의 기초자료로 활용 가능할 것으로 예측된다.

This study is intended to set a greenhouse gas emission scenario based on green remodeling pilot project (Annex building of Seoul Customs Office) using LEAP model, a long-term energy plan analysis model, to calculate the energy saving and greenhouse gas emission till year 2035 as well as to analyze the effect of electric power saving cost. Total 4 scenarios were made, Baseline scenario, assuming the past trend is to be maintained in the future, green remodeling scenario, reflecting actual green remodeling project of Seoul Customs Office, behavior improvement and renewable energy supply, and Total scenario. According to the analysis result, the energy demand in 2035 of Baseline scenario was 6.1% decreased from base year 2013, that of green remodeling scenario was 17.5%, that of behavior improvement and renewable energy supply scenario was 21.1% and that of total scenario was 27.3%. The greenhouse emission of base year 2013 was $878.2tCO_2eq$, and it was expected $826.3tCO_2eq$, approx. 5.9% reduced, in 2035 by Baseline scenario. the cumulative greenhouse gas emission saving of the analyzing period were $-26.5tCO_2eq$ by green remodeling scenario, $2.8k\;tCO_2eq$ by behavior improvement and renewable energy supply scenario, and $2.0k\;tCO_2eq$ by total scenario. In addition the effect of electricity saving cost through energy saving has been estimated, and it was approx. 634 million won by green remodeling scenario and appro. 726 million won by behavior improvement and renewable energy supply scenario. So it is analyzed that of behavior improvement and renewable energy supply scenario would be approx. 12.7% higher than that of green remodeling scenario.

Due to a waste of energy in korea, about 525,000 which are 75 percent of total buildings are at least 15 years old buildings that need remodeling. There are two current remodeling systems. One is a remodeling system to reduce a waste of resources from the reconstruction. The other is a green-remodeling system aimed to energy savings and reducing environmental costs. This study is to analyze quantitatively these current systems with respect to the cost-benefit caused by the life cycle and suggests the political and institutional implications through the interpretation of the results. For a quantitative analysis, we analyzed reducing maintenance costs and rent benefits with simulation by using opportunity costs, construction costs, plan costs and supervision costs as expense variables and using the reduced floor area ratio, institutional incentives, energy, water resources and certified emission reduction(CER) as benefit variables. As a result of the empirical study, the green-modeling was more beneficial in the field of environment such as the energy savings, however, the final benefits of remodeling which has no green building certification costs but more floor area ratio incentives were more economical. The green-remodeling system focused on reducing environmental costs and energy savings needs a equatable institutional incentive system.

Purpose: In case of existing building, A lot of attempts are being made like changing thermal system or using high efficiency products to decrease energy load and increase energy efficiency. However, (1) Absence of systemed database of green-remodeling technology and products. (2) Absence of comparative analysis system and qualitative/quantitative evaluation method of energy performance and energy reduction cost. (3) Existing remodeling was very hard to access for non-experts. So, in this paper, the authors developed data base for green-remodeling(Impact Table A, Impact Table B) and optimum combination dedication tool for user convenience. Accordingly, purpose of this paper validate usefulness of Impact Table and optimum alternative dedication tool. Method: For validate the usefulness of Impact Table and optimum combination dedication tool, the authors selected five test model office buildings.

To receive financial support for the Green Remodeling, applicants must submit an energy simulation report. However, many of the applicants are not green remodeling specialist and energy simulation services are too expensive for them. For this reason, this study was to develop an energy simulation program to enhance green remodeling for the non-specialist such as housewives. Firstly, to enhance understanding and accessibility improvement energy simulation, simulation process was designed four steps and reducing input data. Specifically, input data was reduced by categorizing the following for the area, plan type, hot water load, electricity load, statistical inference. And then, to accurately verify the calculation result, the heat and hot water demand were derived and compared with ECO2 and Energy # program. Lastly, the calculation shows that there is a difference of 4% for the heat load and 15% to 33% for the hot water load respectively.

The purpose of this research is to evaluate the health performance of existing buildings which completed green remodeling using the WELL Building Standard developed by Delos in the USA. The features and the level of improvement in health were examined and the results were as follows. As a result of comprehensive evaluation of the health performance of the target building, the health performance after green remodeling improvement was improved by 17.3% compared to before green remodeling. As a result of applying the alternatives for improving health performance, improvements were 22.9% by Alternative 1, 28.8% by Alternative 2, and 28.7% by Alternative 3. If the improvement ratio with respect to the construction cost were compared, Alternative 1 was the best followed by Alternative 2. Finally, the cost effectiveness of improving health performance against construction cost were best in the order of self-closing door installation, airtight seal, and pest inspections.
