Ltd.10.26689/jera.v9i7.13620ArticleResearch on the Operation Status Evaluation and Energy-Saving Control Measures of Electrical Engineering Facilities and Equipment in Office Buildingshttps://artdesignp.com/journal/JERA/9/7/10.26689/jera.v9i7.13620WuHuichang2025972025-12-31This research focuses on office building electrical engineering facilities. It elaborates on evaluating their operation status using key performance indicators, real-time monitoring, and analyzing baseline energy usage. Energy inefficiency hotspots are identified. The hybrid fuzzy-AHP and dynamic weighting are used in assessment. Prototype validation, comparative analysis are carried out. Energy-saving measures like VFDs and predictive lighting are proposed, along with economic and carbon-emission-related evaluations.
