노후 공공건축물의 현장 조사 결과에 따른 에너지효율등급 평가 결과 분석
배민정(Bae Minjung),안호상(Ahn Hosang),강재식(Kang Jaesik) 한국태양에너지학회 2023 한국태양에너지학회 논문집 Vol.43 No.6
The building energy efficiency grade of old buildings in Korea is rated according to criteria of building energy performance calculated by the ECO2 energy simulation program. To evaluate this performance, ECO2 input data are required, which influence both the intermediate decision process and final calculation results. However, the required input data collection of old buildings for ECO2 simulation is not as simple as expected, and is more difficult than that for new buildings because of many unrecorded changes and updates after the original construction. In these aspects, certification assessment documents for old public buildings are not suitable for preparing input data for ECO2 and usually do not reflect the actual status and condition of buildings from either passive or active perspectives. Therefore, in this study, an ECO2 building energy simulation was performed for 41 old public buildings to examine how input data differences from on-site audits can induce differences in both the simulation process and results. The error range of the primary energy consumption for grades extended from 0 to 231.9 ㎾h/㎡․ yr, depending on whether on-site audit results are considered or not. Because of the long operation period of old public buildings, the initial design plan and current operation status have changed significantly, and our suggestion is that the confirmation step for collecting input data for old public buildings must be a prerequisite and an essential aspect for on-site investigation based on ECO2 simulation.

Recently, the incidence of disaster in buildings is increasing due to insufficient crime and fire prevention and carelessness buildings maintenance. That is why establishment of preventive disaster system against a disaster on buildings is more critical. This study aims for the development of preventive disaster management system for public facilities utilizing thermal imaging camera in order to preventively provide against disasters including building collapse, fire, and facility deterioration. The preventive disaster management system is composed of inspection request, inspection management, and inspection history module for preventive disaster, which is developed in Web-base system considering the usability of users, database compatibility, and real-time information exchange. Based on the inspection history information of preventive disaster that can be obtained by utilizing the preventive disaster management system, the result of this study, preventive disaster in terms of deterioration of natural disaster, and an effect minimizing damages through quick action would be expected.

BIM 역설계를 활용한 노후 공공건축물 리모델링 건축 계획 방향 연구
조준영(Jo, Jun-Young),이명식(Lee, Myung sik) 대한건축학회 2022 대한건축학회 학술발표대회 논문집 Vol.42 No.1
Currently, in the case of domestic remodeling projects for buildings that are more than 20 years old, investment in private facilities is active due to economic advantages. However, public facilities lack in this field due to a limited budget. In order to perform optimal remodeling within this limited budget, it is necessary to introduce BIM reverse engineering. Therefore, this study establishes an effective plan and design through the analysis of definition and process of BIM reverse engineering technology and introduces BIM reverse engineering to enable optimal remodeling and planning for areas with severe dilapidation due to aging to contribute to user comfort, usability, durability and economic feasibility and at the same time induce rational maintenance process.
