Our client had set ambitious energy and carbon reduction targets for their site. To assist with achieving these targets, Prochem were engaged to identify and deliver energy and carbon reduction projects which included the upgrade of the chilled water plant. The project was delivered through the SEAI EXEED (Excellence in Energy Efficient Design) process where we undertook the role of EED Expert and coordinated the successful drawdown of an EXEED Grant.
The chiller upgrade project achieved a number of key goals including:
- Energy in-use reduction.
- Reduced carbon generation.
- Transition to low GWP refrigerant.
- Improved system redundancy and robustness.
- Introduction of heat recovery from the chilled water plant which reduced the client’s reliance on gas fired boilers.
- Upgrade of the existing CHW distribution system to improve energy efficiency.
A dominant aspect of this project was the restraint of no down time of chilled water supply to production during site operations. The constructability aspect of the project was a particularly challenging aspect of the project delivery and detailed planning and scheduling was carried out by Prochem in advance. Offsite construction was utilised where possible to minimise site construction impacts and improve schedule timelines. A collaborative approach between Prochem, the Client and the Contractor Team was key to the successful handover of the utility system on time with no manufacturing impact.
