  • As time passes, the aging of the plant building, the building's energy performance degradation than the initial plan does not express a situation could arise. This year, the certification of buildings certified in 2009 has expired for measures such as the situation required. In this study, management of national and international green building certification and re-certification was compared in two ways. First, the evaluation of green building certification system management assessments were compared. Second, the green building certification system for the re-certification analysis. As a result, G-SEED was not reflected life-cycle of building in management assessment and the commissioning of G-SEED is the UK and the U.S and other concepts of evaluation. In addition, the re-certification system is insufficient about substantial energy consumption of buildings. In this study, the revised the management assessments in conjunction with the re-certification system to manage the building is proposed to improve. In addition, the current evaluation of the existing building certification "existing building" and "building the first certified" as it is more efficient to separate the information into assessment was judged. Green building certification system to meet the purpose of management and operation, and disposal phases of the building to promote energy conservation and sustainability in order to the management a systematic and detailed evaluation and re-certification system developed for the revision of the specific items required and future research want to continue.

  • We aim to use public data different from the remote BEMS energy diagnostics technology and already established and then switch the conventional operation environment to a big-data-based integrated management environment to operate and build a building energy management environment of maximized efficiency. In Step 1, various network management environments of the system integrated with a big data platform and the BEMS management system are used to collect logs created in various types of data by means of the big data platform. In Step 2, the collected data are stored in the HDFS (Hadoop Distributed File System) to manage the data in real time about internal and external changes on the basis of integration analysis, for example, relations and interrelation for automatic efficient management.

  • This paper presents an automated computer vision-based system to update BIM data by leveraging multi-modal visual data collected from existing buildings under inspection. Currently, visual inspections are conducted for building envelopes or mechanical systems, and auditors analyze energy-related contextual information to examine if their performance is maintained as expected by the design. By translating 3D surface thermal profiles into energy performance metrics such as actual R-values at point-level and by mapping such properties to the associated BIM elements using XML Document Object Model (DOM), the proposed method shortens the energy performance modeling gap between the architectural information in the as-designed BIM and the as-is building condition, which improve the reliability of building energy analysis. Several case studies were conducted to experimentally evaluate their impact on BIM-based energy analysis to calculate energy load. The experimental results on existing buildings show that (1) the point-level thermography-based thermal resistance measurement can be automatically matched with the associated BIM elements; and (2) their corresponding thermal properties are automatically updated in gbXML schema. This paper provides practitioners with insight to uncover the fundamentals of how multi-modal visual data can be used to improve the accuracy of building energy modeling for retrofit analysis. Open research challenges and lessons learned from real-world case studies are discussed in detail.

  • With the enactment of the "Framework Act on Carbon Neutrality and Green Growth to Cope with Climate Crisis," various sector-specific plans are being implemented to achieve carbon neutrality. School facilities are mandatory buildings for the "Zero Energy Building Certification" and are the buildings that account for the highest proportion among public institution buildings. Therefore, they play a major role in achieving carbon neutrality in the construction sector. This study analyzed the recent energy use trends and zero energy levels in varied ways to promote the spread of building energy management systems and to provide basic data for efficient operation management and investigated the effectiveness and user opinions of the Building Energy Management System (BEMS) applied to school facilities.

  • For the effective energy management, this study proposed BIM(Building Information Modeling)-based Data Mining Model(B-DMM). To conduct this, BIM-based data mining researches were surveyed then the use-cases and scenarios related to the energy management were analyzed. By using this results, B-DMM for supporting the decision making related the energy management was proposed. The output will be used as a decision making tool for managing a building energy.

  • Conservation of energy and fuel is the trend in smart building design. Radio Frequency Integrated Circuit (RFIC) technology is often used in temperature sensing and signal transmission to manage indoor temperature, but it is rarely applied to the shell of the building. Heat retention and poor insulation in building shells are the largest causes of high energy consumption by indoor air conditioning. Through combining RFIC technology with temperature sensors, this study will develop smart temperature information material that can be embedded in concrete. In addition to accurately evaluating the effectiveness of shell insulation material, the already-designed Building Physiology Information System can monitor long-term temperature changes, leading to smarter building health management.

  • Now, in Korea, the performances of the building service equipment relay on the individual superintendent's share for the assessment of performance, fault detection, deterioration diagnosis of the building service equipment. As the result, very different quality of the performance or the durability of equipment is being obtained with his skill and effort and it is also not easy to assess that quality. This finally lead to the waste of labor force and the operating cost due to the high-cost, low-efficiency system. How to construct the N-BMS was considered to save energy, resource and to conserve performance of building service equipment. The FEMIS, facility, energy/environmental management & information system, for building service offer management process integrated with BAS, FMS and EMS and so on.
