We retro-commissioned the University of Pittsburgh Medical Center's (UPMC) 520-bed Shadyside Hospital. After investigating operations and equipment through observation, functional testing, and diagnostic monitoring, we recommended and implemented seven energy-reduction strategies:

  • Water-side testing, adjusting, and balancing (TAB)
  • Terminal unit scheduling
  • Air handing unit (AHU) scheduling and control optimization
  • Air system variable frequency drive (VFD) installation
  • Hot water system VFD installation and controls reprogramming
  • Chilled water system optimization
  • Operating room unoccupied mode scheduling

2,373,000 kWh

annual electrical energy savings

190,190 therms

annual gas savings

$264,5620

total annual savings

Following construction, we scheduled a measurement and verification (M&V) period to track energy savings and developed a real-time building layout for performance evaluation.
