Williams Dinning Hall Retrocommissioning

Retrocommissioningis the process of the commissioning an existing building. This process seeks to improve how building equipment and systems function together. Depending on the age of the building, retrocommissioning can often resolve problems that have occurred during design or construction, or address problems that have developed throughout the building's life. Overall, retrocommissioning improves a building's operations and maintenance in efforts to enhance the overall building performance.

Williams Dinning Hall's retrocommissioning is projected to save 360,273kwh, and 20,086 therms annually. These savings will result in a annual utility savings of $33,668 as seen below.
