Northwestern Medicine, Multiple Facilities

Chicago, IL

Northwestern Medicine campus, exterior


GBA provided retro-commissioning services for multiple downtown Chicago facilities on the Northwestern Medicine campus. The four projects, completed over a three-year period, totaled about 4.2 million square feet. Facilities ranged from 362,800 square feet to 2.2 million square feet, with verified annual savings ranging from $45,673 to $206,557 a year. Projects were supported by retro-commissioning incentives from electrical utility ComEd.



Cost savings identified by GBA at four Northwestern Medicine buildings totaled $324,464/year for electricity and $87,377/year for natural gas. The largest single annual savings identified was $206,557/year (electricity and natural gas combined) at the largest facility retro-commissioned: the Feinberg/Galter Pavilion. Common implemented RCx measures included economizer optimization; supply air temperature reset; demand-based supply/return static pressure reset; condenser water temperature reset; equipment scheduling (night temperature and airflow setbacks); and minimum outside air balancing. In every case, paybacks for implemented measures were less than 1.3 years; most were less than six months.
