Technology at Work: Energy Management / Performance Management

Energy Management: Knowledge about Power

• Know your Baseload. What can be reduced?

Is Daylighting an option?

Consider the correct Occupancy Control System

Demand-Based Controls are Smart

• CO2 Demand-Controlled Ventilation

Demand-Based Controls are Smart

• Chilled Water System Demand-Based Reset

Optimization Controls minimize kWh consumption in real-time

Retrocommissioning (RCx) finds issues

Continuous Commissioning > RCx

“Hands-off my Operating Rooms!!”

Operating Room Setback Strategies

• ORs typically occupied 10% to 20% of the year • Reduce airflow by 75% when in standby • Temperature, Humidity, Differential Pressure should stay

constant

Performance Management: You CAN’T Measure Energy Savings

• How did my Improvements do? Other Factors?

• IPMVP or FEMP (Federal)

M&V Plans determine Utility Avoidance

• M&V Plan defines savings analysis BEFORE improvements are implemented

– Option A. Retrofit Isolation: Key Parameter

– Option B. Retrofit Isolation: All Parameter

– Option C. Whole Facility/Meter

– Option D. Calibrated Simulation

• Savings Report quantifies the

avoided energy use

Energy Benchmarking: You can’t manage what you don’t measure

1. Compare against Past Performance

2. Compare against Industry Average (Peer Group)

3. Compare against Best in Class

4. Compare against Best Practices

• ENERGY STAR’s Portfolio Manager

• EUI (Energy Use Index) = total consumption/ft2

• other proprietary formats
