Case Study: Kings College London, New Hunts House

Whole site BMS upgrade and optimisation

Environment

Kings College London, New Hunts House includes a library covering all aspects of biomedical science along with central offices and scientific support laboratories located near Guy’s Hospital in London.

 

New Hunts House contains Biological Services in a multi-disciplinary core research facility providing services and advice to research scientists and clinicians carrying out animal research. The facility provides state-of-the-art support for any projects involving genome editing and has a successful track record in the creation of transgenic animals. It also provides a general mouse embryology service for the cryopreservation and re-derivation of lines.

 

A critical building containing a vast Building Management System controlling all HVAC plant and monitoring systems throughout the various floors of the building.

Identification

The building management system at New Hunts House is comprised of numerous bespoke BMS mechanical control panels situated throughout the building. Many of these control panels are located within the roof plant room serving mechanical plant across the floors. The existing control panels housed various Building Management System controllers of obsolete Siemens manufacture which were utilised to control and monitor heating, ventilation, air conditioning and general mechanical and electrical plant.

 

The obsolete Siemens manufacturer controllers were due to be upgraded as part of life cycle upgrade works to ensure dependence on the BMS system for future development of the site. The vast scale of the site meant that maintaining the old obsolete control system through resourcing spare parts was proving difficult. This, coupled with other Kings College London buildings being of Trend BMS control system, meant that this site would be changed to Trend to ensure uniformity across their estate with the vision of merging the Building Management System to a central location.

Solution

A vast number of Siemens controllers were identified across the site, many contained within 19 bespoke building management control panels. A total of 20 No. main outstations and 334 No. remote FCU controllers were replaced as part of Trend upgrade works.

The critical nature of the site meant that the vast upgrade works were scheduled in stages and carefully planned around minimal downtime. Many of the upgrade works took place out-of-hours to reduce disruption.

 

The New Trend IQ4 variation controllers were installed within each of the main control panels, carefully sequenced and staged to create as little impact as possible. Many of the new Trend controllers were positioned on new pre-wired back plates, installed in replacement over the existing ones to ensure a reduced level of downtime of the BMS system and mechanical plant serving critical areas.

 

New BACnet MSTP network cabling was installed throughout the 5 floors of the building to replace the existing Siemens with Trend IQECO fan coil unit controllers. A phased changeover of the FCU controllers was carefully scheduled with the building occupants to ensure the movement of equipment during high-level working.

 

Once all physical Siemens controllers were replaced with Trend IQ4 variants, a new centralised PC supervisor was installed containing the latest IQVision software for control, monitoring, and changes by the facilities maintenance team.

 

The whole site upgrade has improved the visibility and functionality of the mechanical and electrical plant installed throughout the building. Centralised graphical representations and alarm management ensure full control and monitoring of the site for both maintenance staff and KCL personnel.
