Centre for Advanced Photonics and Electrics

To unify its building management systems and advance its sustainability objectives, the University of Cambridge’s Estates Division embarked on a significant upgrade at the Centre for Advanced Photonics & Electrics building. Managed by CPS Building Services, this initiative focused on replacing an outdated Honeywell BMS with a TREND system to align with the rest of the estate and introducing new, more efficient climate control equipment.

The previous VRF system, which had served various rooms across the ground and first floors for around 18 years, was replaced as part of this project. The new installations included thirteen new two-pipe split air conditioning systems, replacing older units on a like-for-like basis. This change was aimed at reducing energy consumption and carbon emissions. CPS made every effort to retain much of the existing infrastructure-such as VRF pipework, ductwork, electrical cabling, and condensate systems-to ensure continuity and minimise the environmental impact of the upgrades.

The transition to a TREND BMS was strategically chosen to standardise technology across the university, facilitating easier system management and better integration with existing infrastructures. All equipment removal and disposal were conducted in strict compliance with F-gas regulations, underscoring CPS’s commitment to environmentally responsible practices. To minimise campus disruption, particularly during busy times, the replacement of external condensers was managed through crane operations scheduled over a weekend. Completing the project ahead of the tight schedule further minimised disruption.
CPS is proud to have delivered these upgrades with high standards of environmental care and minimal disruption.
