Module 16 Case Studies in Performance-Period Administration

This case study presents a detailed analysis of performance period administration and the enforcement of Energy Conservation Measures (ECM) within a healthcare facility. Covering a variety of clinics, including pediatric, internal medicine, surgical, and others, the study illustrates the implementation costs, financing, and guaranteed savings from energy efficiency projects. Key challenges and resolutions, such as control system recalibrations and the importance of sound measurement and verification practices, highlight critical lessons learned for future projects.

  1. Module 16Case Studies in Performance-Period Administration Enforcing ECM Performance Requirements — Healthcare Facility

  2. Example • Site: Health-Care facility • Primary Care Clinic • Pediatric Clinic • Internal Medicine Clinic • Surgical Clinic • Physical Therapy • Optometry Clinic • Occupational Medicine Clinic • Public Health and Education Center with pathology, radiology, and pharmacy services • Dental Clinic

  3. Project Economics • $1,326,000 Implementation Price • $260,000 Pre-Performance-Period Payment • $186,000 Finance Procurement Price • $1,252,000 Total Amount Financed • $188,300 Estimated First-Year Savings • $170,100 Annual Savings Guaranteed • $95,000 Construction-Period Savings (paid with first-year payment) • 17-year term

  4. ESPC Scope of Work • HVAC Modifications • Chiller and Cooling Tower Replacement • HVAC Controls • Energy Management Control System • Lighting Upgrades • T12 to T8 Relamping • Submetering • Install water meter so building can be changed from billing /SF to metered billing • Natural Gas and Electric Meter Existing

  5. Economics

  6. M&V Approach • Chiller and Cooling Tower Replacement • Option C • Energy Management Control System • Option C • Lighting Retrofit • Option C • Submetering • Option A

  7. First-Year M&V Report

  8. A Closer Look

  9. Problem • DDC control system night setback not able to return areas to normal operating conditions. • Agency overrides night setback to continuous operation. • Higher than predicted run hours. • ESCO takes $15,500 annual credit for override.

  10. Resolution • Recommissioning of the system • Re-evaluation of thermostat location • Recalibration of thermostat and sensors • Verify setpoint temperatures • Review sequence of operations • Verify AHU discharge temp controls operating • Check outside air sensor operation • Install humidity sensor in occupied space • ESCO responsible to return areas to conditions established in DO RFP by the start of next occupied period.

  11. Lessons Learned • Sound M&V plan provides basis for evaluation • Government review of annual report identifies shortfall • Detailed DO RFP provides sound backup to M&V plan • Working together can provide workable solution
