Case Study: Retro-Commissioning
Utility tracking and benchmarking provides valuable insights into building performance while also uncovering opportunities to improve performance and reduce operating costs.
200 W. Adams
200 W. Adams, a highly efficient and all-electric commercial office property, realized notable annual energy savings largely through equipment programming changes. With a $15k investment in retro-commissioning, the property achieved $32k in verified annual energy savings, the equivalent of a 7% reduction in total house energy use.
420 E. Ohio
420 E. Ohio, a multifamily property built in 1991, also achieved significant energy savings through a rigorous retro-commissioning effort aligned with the property’s LEED certification. The property implemented five energy efficiency measures which resulted in verified annual electricity savings of $20k. With a net investment of $23k, retro-commissioning resulted in a 1.2 year payback.
