UK: 120 Cannon Street, a landmark office building in the City of London, has been equipped with Toshiba heat recovery VRF air conditioning as part of a major refurbishment project.
The prominent building, located near The Bank of England and owned by the City of London Corporation, has been redesigned to provide 27,575ft2 (2,562m2) of grade A office space, with a comfortable indoor environment provided by Toshiba’s SHRM-e heat recovery VRF air conditioning. The high-efficiency system contributed to the building earning a BREEAM Excellent rating.
Consultant Designer Group specified a total of 10 roof-mounted Toshiba outdoor units, connected to 135 ceiling-mounted slim-duct indoor units for the upper storeys, and a digital inverter condensing unit and hi-wall fan coil unit for the basement. The equipment was installed by contractor London AC Ltd.
Key to satisfying BREEAM’s energy monitoring requirement was the use of Toshiba’s BMS-CT2560U-E touchscreen central controller, used in conjunction with the company’s BMS-IFWH5E energy monitoring interface. The controller enables landlords to manage VRF heating and cooling in multi-tenant buildings, providing schedule programming and full function control of all connected indoor units.
Local indoor climate control is provided for each of the nine upper floors for use by the tenant, with the central controller connected to the building management system for high-level integration and monitoring.
In addition to delivering improved energy efficiency, the project is also designed to enhance the feeling of space, with ductwork and air diffusers serving offices fully exposed.
The refurbishment and upgrading project was carried out for The City of London Corporation by main contractor 8build.
