Which system must have data logging capabilities and be connected to central monitoring?

The answer, which indicates that all meters must have data logging capabilities and be connected to central monitoring, is correct because effective building management requires comprehensive oversight of various resource usage, including energy and water.

All meters, whether they are energy, water, or other utility meters, play a crucial role in tracking usage patterns and identifying inefficiencies. By having data logging capabilities, these meters can continuously record usage data over time, which aids in making informed decisions regarding resource management. Connectivity to a central monitoring system allows for real-time analysis, alerts for unusual consumption patterns, and historical data review, which is crucial for making strategic improvements.

This integration is fundamental to achieving sustainability goals outlined in the Estidama Pearl Building Rating System (PBRS), as it enables building operators to optimize performance and ensure compliance with efficiency standards.
