Retro-commissioning, also referred to as recommissioning, reduces energy use and cost in buildings by identifying opportunities to optimize the HVAC system. When properly executed, retro-commissioning reduces annual energy use by 5–10%, and sometimes up to 20%, with limited expense exposure and negligible disruption. Furthermore, many utilities offer retro-commissioning incentive programs that help underwrite project costs leading to outstanding ROI.
Although not as common as energy audits, retro-commissioning is a well-established and worthwhile service suitable for almost every building. Even buildings where energy audits or assessments have been performed recently may be excellent candidates for retro-commissioning. The energy engineers at Sieben Energy Associates have earned a strong reputation for delivering results. Our portfolio of retro-commissioning projects comprises over 55 million square feet and has generated over 50 million kWh of annual electricity savings and over 1 million therms of annual natural gas savings for our valued clients.
