Here are 10 of the most common ways analytics has been implemented to improve energy efficiency, occupant comfort, or reduce maintenance time.
1. Identify broken dampers and valves as they break.
2. Automatically calculate the energy and cost impact of broken equipment, such an outside air damper stuck open.
3. Prioritize the current operational issues based on their relative cost impact.
4. Identify unnecessary periods of simultaneous heating and cooling.
5. Identify sensors drifting out of calibration.
6. Compare current facility operation to the “typical” day, week, or month during similar weather.
7. Compare energy use of one building to other buildings across a campus, accounting for size and other factors, with real-time granular data (15-minute intervals instead of traditional monthly utility data).
8. Compare similar equipment, such as chillers or boilers within a plant, to determine which is most efficient.
9. Analyze current energy spend and predict future energy spend.
10. Analyze occupant comfort data to pinpoint trouble areas.
