At the upcoming Intelligent Building Conference (IBcon), our work with Banner Thunderbird Medical Center is being featured at the Smart Buildings Best Practice Showcase. Banner Health contracted with ETC Group to implement monitoring-based commissioning (MBCx) at the Banner Thunderbird campus and despite challenges, the project has been a great success. This project achieved an annual energy cost savings of $449,000 with an internal ROI of 194%.

Background: Medical centers (and mission critical, 24-hour facilities) use a lot of energy. After completing numerous energy projects, Banner’s energy management team observed that savings and performance gains eroded over time (drift). They also wanted to increase operational visibility to identify new opportunities while maintaining savings for completed projects.

Solution: ETC Group deployed a custom analytics and fault-detection platform (SkySpark) and provided engineering consulting service and project management throughout a year of measure implementation. This approach streamlined their ability to:

  • Monitor facility performance
  • Discover evidence-based savings opportunities
  • Implement upgrades
  • Verify the performance of upgrades
  • Continue to optimize performance into the future
Challenges: Successes:
Working with legacy controls nomenclature and integration Annual energy cost savings of $449,000 with internal ROI of 194%
Lack of historic test and balance documentation Utilization of custom utility rebate structure to support the project
Lack of sub metering and confusion on loads served by existing metering Partnering with Climatec to deliver desired controls and mechanical solutions
Coordination and communication of numerous action items among implementation teams Banner effectively supported MBCx program with dedicated time from key operator personnel
Verification of weather-dependent measures with time frame for utility rebate purposes ETC Group utilized multi-variable non-linear power regressions for measurement/verification of savings
