Commissioning and Retro-Commissioning

Building commissioning is the process of confirming and documenting that your building systems are functioning according to criteria set forth in the project documents to satisfy the owner’s operational needs. Commissioning of an existing building, also known as retro-commissioning, is a systematic process for investigating, analyzing, and optimizing the performance of building systems by improving their operation and maintenance to ensure continued performance over time.

AEA has been diagnosing, specifying, and providing quality assurance and verification for central plant upgrades in multifamily and commercial properties for many years. Our energy engineers can provide the critical link between the owner, design team, mechanical engineer, and construction team. A formal commissioning process is meant to ensure that the building operates as the owners and occupants intend it to.

Commissioning of an existing building, known as retro-commissioning, may be offered as part of a comprehensive energy audit, to enhance operations and maintenance and to meet changing demands of a building’s occupants. Following a formal commissioning process during a retrofit or new construction project provides the owner with many valuable benefits.

Many municipalities  have passed ordinances requiring buildings of certain size or type to undergo periodic retro-commissioning as part of a broader set of energy efficiency tracking and planning steps

AEA is uniquely qualified to provide commissioning services either as a third-party or as part of the design/specification team. Contact us to discuss your building’s needs at
