Project Information
- Client:
- City University
- Sector:
- Education
- Duration:
- 14 Months
- Services:
- M&E Services Installation
As a result of this solution, heating in the winter is powered by the CHP system and cooling in the summer is provided by the absorption chiller.
Scope of Works
To deliver this CCHP solution, our team installed an 800kW(c)/950W(h) CHP, 500kW absorption chiller, 1.5mW heat rejection plant and a new 1mW turbo-core electric chiller.
New risers were also installed as well as a new chilled water ring main unit, which serves buildings and integration with the existing 6mW boiler house, LV system cabling to plant, BMS and controls. As a result, heating in the winter is powered by the CHP system and cooling in the summer is provided by the absorption chiller.
Benefits of a CCHP Solution
The benefits of a CCHP solution include:
- On-site, high-efficiency production of electricity and heat
- Reduced fuel and energy costs
- Lower electrical usage during peak summer demand
- Significant reductions in carbon emissions
- Improved Building Energy Performance Certificate ratings
