Abstract

A methodology for operational schedules optimisation is introduced to reduce energy demand by exploiting monitored occupancy patterns for dynamic thermal model calibration. Significant periods of low occupancy were identified on a case study building to leverage with proactive operational strategies to reduce energy demand. These strategies involve the closure of specific building zones during these periods to optimise resource utilisation. Up to 6% annual energy savings was estimated, highlighting the effectiveness of zone closures. The study’s replicable data-driven framework can be scaled and extended to other buildings, with potential for widespread energy efficiency enhancements and cost reductions across similar type buildings. The research enhances the understanding of the relationship between occupancy and energy demand, while offering adaptable recommendations for more energy efficient and sustainable building operations.
