The 227,000 sq ft 1970’s office and retail building was comprehensively refurbished in 2012 with a development cost of around £150 million. The redevelopment, designed by Aukett Fitzroy Robinson includes replacing all the building’s glazing and shopfronts to improve energy efficiency and maximise the internal natural lighting. A new roof has been added, and the canopy removed allowing the original award-winning architecture to come back to life. Internally the building has been completely stripped out, the service core and reception areas reconfigured and all plant and machinery replaced.

The property comprises a mixed-use building fully refurbished in  2012, providing basement and  ground floor retail accommodation with office space on the remaining  floors.

The Building Management System (BMS) serves to control and monitor the main HVAC plant and miscellaneous systems within 123 Victoria Street. The Delta based system is an automatic control system, utilising decentralised control with distributed intelligence. Programmable intelligent outstations are located, generally with Control Enclosures (CE) local to the plant they serve. NG Bailey manage and maintain the landlord and tenant services on behalf of Landsec. The BMS system within the building is controlled via the Delta Enteliweb supervisory software. The Delta Enteliweb supervisory software is currently operating on version 4.12 and requires updating to 4.20 including the latest security updates. There are large numbers of BMS controllers that have time limited support by the manufacturer, therefore there is a risk that these unsupported BMS controllers could fail and have a negative impact on the building operation.

The scope required Hive to independently review the existing BMS systems in order to provide a clear and concise insight into the installed systems. The feasibility study provided an overview of the systems with regards to LandSec’s overarching long term Net Zero Plan for its London portfolio.

The feasibility report included the proposed transition path, road map for the upgrade and outline costs, necessary for future service charge budgets. Hive liaised with all parties on-site including the incumbent main contractor, BMS contractor, Tenants and client teams to build a comprehensive picture of the installed control systems.
