The document discusses retro-commissioning efforts at a facility with 4.9 million gross square feet across 41 buildings ranging in age from 1910 to present. It involved gathering building data, calculating heat loads, assessing deficiencies, documenting equipment, and prioritizing work. Previous retro-commissioning projects resulted in $380,000 annual savings over 3 years for one building and $5 million annual savings in FY05 with $26 million in total savings from FY92 to FY05 for the organization. The retro-commissioning addressed issues like aging equipment, space use changes, budget pressures, and knowledge gaps.
