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.
