During the life of a building many changes are often made to a BMS to accommodate staff comfort or operational changes to the building itself. These changes may simply involve setpoint changes, changes to operating times, or even changes to the software strategy itself. Often these changes lead to inefficient plant operation. E2’s recommissioning service returns the BMS to its originally intended operation, extending the useful life of a BMS system and ensuring the building runs at the most economic level. For example, our recommissioning project of the Cylon BMS at Microsoft resulted in over 30% savings.

E2 can advise whether a recommissioning exercise is suitable for your building, or whether a full upgrade is needed.
