Retro-Commissioning

Retro-commissioning, also known as existing building commissioning, is a process that improves the energy efficiency of building operations. This solution is ideal for buildings that have never been commissioned as well as for those that have not been commissioned within the past five years or so. Retro-commissioning analyzes building systems, equipment, and operations in search of low-cost and no-cost improvements. After the energy reduction measures are implemented, the SEA commissioning team measures and verifies the success of the solutions.

Buildings that benefit from retro-commissioning may have issues such as high utility bills, excessive levels of maintenance, or comfort control problems. Both retro-commissioning and energy audits provide valuable feedback on how to make a building more efficient. Retro-commissioning is more extensive, however, because SEA not only recommends measures, but also confirms that the installation of new equipment and modifications to existing equipment are completed correctly. SEA's engineering team will monitor energy usage closely both before and after installation.

ComEd Retro-Commissioning Incentive Program

Eligible facilities in the ComEd service territory of northern Illinois may qualify for free retro-commissioning services from SEA. This is a great opportunity to optimize building performance and reduce energy expenditures for years to come. The only cost to participants is a nominal expense for the implementation of measures recommended during the process; the simple payback for these low-cost measures is typically less than one year. As an active Service Provider for this program, we have successfully reduced energy usage and expenses for a wide variety of building types, from hotels and office towers to hospitals and data centers.
