Due to the scale of the project a phased approach was essential. In addition, continuous monitoring of the improving performance allowed each new phase to build upon proven results.
Phase 1: a new Energy Centre with a 3.4MWe CHP, two 12MW gasfired MTHW boilers and a “supplementary” 12 MW waste-heat boiler. Our architect designed the RIBA award-winning Energy Centre building and NIFES used 3-D modelling to co-ordinate the installations. Phase 1 also included a new DH network for the main campus (£18m).
Phase 2: extended the DH networks and developed an intelligent heating system with optimised controls for maximum energy savings. (£4m)
Phase 3: comprised two further 2MWe CHPs added within a Listed Building. (£8m)
The district heating installation, powered by new efficient boilers and correctly sized CHPs, has enabled the University of Liverpool to make substantial operating and economic efficiencies. In addition to reduced costs for maintaining heating plant they now achieve energy savings of over £1m each year and have cut annual emissions by more than 6,000 tCO2.
