Project Summary

The ComEd^® Energy Efficiency Program new construction team partnered with Sunstar to identify energy conservation measures (ECMs) that would meet organizational sustainability design goals and financial payback requirements. As a result, 19 ECMs were incorporated and incentivized through the program.

The Solution

The ComEd team provided energy modeling services, and calculated energy savings and incentives for implementation of the following ECMs:

• High-performance envelope strategies
• Interior and exterior lighting power density reduction
• Fixture-based occupancy controls for lighting in areas not required by code
• High-efficiency equipment installations
• Pressure and CO₂ sensor installations to control mechanical equipment components in the office
• Use of a BAS to modulate systems in warehouse and manufacturing areas
• Process equipment upgrades, including:
  • Switch to water-cooled chillers served by an open cooling tower with heat exchanger and variable speed fans
  • Upgrade to variable-speed, two-stage, water-cooled compressors
  • Addition of variable-frequency drives for pumps
  • Installation of a winter cooler to provide process chilled water during appropriate outdoor conditions

Project Benefits

Sunstar qualified for technical assistance and the project received $397,100* in total incentives from ComEd. The new 302,000 ft2 facility in Schaumburg reduced estimated energy costs by $320,200** annually and earned LEED certification in 2017.
