energy usage with increased accuracy, granularity and reliability • Lack of models that fully characterize occupancy behavior with the
Enterprise/Organiza2on that will be housed in the facility/building under design
• Enrichment of exisBng BPS tool with occupancy paZerns & individual user profiling
