Green Building Design successfully delivered there placement of a major cooling system at the Trinity Centre, Cambridge SciencePark. The project involved removing a failed 25-year-old rooftop package chiller and installing a newer, energy-efficient replacement unit to maintain comfort for occupants and visitors.
The existing plant had reached end of life and was no longer able to provide cooling to the building’s air handling and fan coil unit systems. With tenants set to remain in the building for a further three to five years, restoring reliable air conditioning was a priority.
A number of replacement cooling solutions were considered, with costs and installation impacts carefully reviewed. During this process, a high-quality 18-month-old chiller unit from a neighbouring building on the Science Park became available. Following detailed suitability checks, the decision was made to repurpose and install this unit at the Trinity Centre.
The works, carried out during June and July 2025, involved safely removing the chiller from its previous location and integrating it into the Trinity Centre’s existing plant systems. The project was completed successfully, and the new installation is now fully operational, delivering effective cooling across the building.
Key Features
- Removal of failed 25-year-old rooftop chiller unit.
- Identification and suitability testing of an alternative chiller sourced from a neighbouring building.
- Installation of an 18-month-old package chiller, repurposed to provide an energy-efficient replacement solution.
- Careful planning and execution to minimise disruption to tenants and maintain building occupation during works.
- Integration of the new chiller with the existing AHU and FCU systems to restore full cooling capacity.
The Trinity Centre project is another example of GreenBuilding Design’s commitment to delivering sustainable, cost-effective retrofit solutions that extend the life of building assets while supporting occupant comfort and operational efficiency.
