Barbican Estate Set New Heating Control. Following the completion of an option appraisal for the City of London Corporation carried by Concero, the Barbican Estate is set to have a new state of the art BMS (Building Management System) installed. The new BMS will control the estate wide under floor heating system and will replace the current Cyclo control arrangement. The BMS will also offer scope for expansion allowing for further control and monitoring of the heating system enabling energy efficiencies to be gained. Concero were instrumental in drafting the technical specification and assisting in the contract procurement.
