The project

The King’s School WitneyA school campus expansion project, intially proposed to provide additional space so that both upper and lower school pupils could be accommodated at the same campus. The scope of the project also included the provision of further facilities for students and the local community.

The Challenge

To provide a means of energy generation, for project compliance with building regulations, that would keep project costs to a minimum and enable the capital outlay to be recouped quickly.

Summary of site demand

Annual electricity demand……………………………………………..64,518 kWh
Electricity price………………………………………………………………7.7 p/kWh
Annual heat and DHW demand……………………………………….195,851 kWh
Gas price…………………………………………………………………..3.537 p/kWh

The solution

Supplied and installed one 15kWe/30kWth LoadTracker CHP unit supplying 73% of site heating and hot water demand and 61% of site electrical demand. System design needed to incorporate a heatpump supplying 25% of heating.

Features

  • case-study-gun-wharf-image6LoadTracker automatically modulates electrical output, which minimizes unnecessary grid electricity consumption.
  • Long service intervals (8,000 hours or 2 years).
  • Provides on-site energy generation through the development of a new CHP distribution network.

Benefits

  • Carbon Footprint Savings
  • Cost Savings

Carbon footprint savings

22 tonnes of CO2 emissions could be reduced by installing a CHP system relative to a conventional mains supply/ gas boiler system.
This is an equivalent 27% reduction of CO2 emissions.

Cost Savings

The use of LoadTracker CHP would result in annual savings of £3,094 relative to a conventional mains supply/ boiler system.
This is equivalent to saving 22% on energy bills.
