碩士 === 國立臺灣科技大學 === 建築系 === 104 === Individual buildings within university campuses are often occupied by different departments in Taiwan, which has created a great challenge to the energy management task. To assist individual departments within universities in their energy management tasks, this study explores the application of Building Information Modelling in establishing the ‘BIM-based Energy Management Support System’ (BIM-EMSS). The BIM-EMSS consists of five components: (1) sensors installed for each occupant and each equipment, (2) electricity sub-meters (constantly logging lighting, HVAC, and socket electricity consumptions of each room), (3) data warehouse (for storing occupancy status and logged electricity consumption data), (4) BIM models of all rooms within individual departments’ facilities, and (5) energy management console that provide energy managers with energy management functions such as occupancy and equipment status display, energy consumption analyses and energy anomaly detection. Through the energy management console, the energy manager is able to (a) have 3D visualization (BIM model) of each room, in which the occupancy and equipment status detected by the sensors and the electricity consumptions data logged are displayed constantly; (b) to review daily, weekly and monthly energy consumption profiles and compare them against historical energy profiles; and (c) to obtain energy consumption anomaly detection warnings on certain rooms so that energy management corrective actions can be further taken (fault detection and diagnostic logic is employed to analyze the relation between space occupancy pattern with current space equipment setting to indicate an anomaly, such as when appliances turn on without occupancy). The BIM-EMSS was further implemented in a research lab in the Department of Architecture of NTUST in Taiwan and implementation results presented to illustrate how it can be used to assist individual departments within universities in their energy management tasks.
