School Comparison Tool

This tool allows you to compare the energy performance of a number of schools within a Local Authority group or across the whole of Energy Sparks. The aim is to allow you to identify the best and worst performing schools to provide examples of best practice and to identify the schools needing the most support to improve their energy management.

Change in annual CO2 emissions since last year

This is HTML content

This benchmark compares the change in annual CO2 emissions between the last two years. All CO2 is expressed in kg (kilograms).

School name CO2 (previous year) CO2 (last year) Change in annual CO2
Saltford C of E Primary School 87,100
Aspire Academy 26,500 21,800 -18%
IKB Academy 16,200 10,800 -33%
Wellsway School 117,000 72,500 -38%
Sir Bernard Lovell Academy 127,000 72,100 -43%

Breakdown of CO2 emissions change since last year

This is HTML content

This chart provides a breakdown of the change in CO2 emissions between electricity, gas and solar PV, and allows you to see which has increased and decreased.

Generally an increase in solar PV production between last year and the year before, would lead to a reduction in CO2 emissions in the chart below, as the more electricity is produced by a school's solar PV panels the less CO2 a school emits overall.

The solar PV CO2 columns in the table below are emissions the school saves from consuming electricity produced by its solar panels, and the benefit to the national grid from exporting surplus electricity. It's negative because it reduces the school's overall carbon emissions. The solar CO2 is calculated as the output of the panels times the carbon intensity of the national grid at the time of the output (half hour periods). So for example a reduction in CO2 offset by the school's panels from one year to the next doesn't necessarily imply a loss of performance of the panels but potentially a decarbonisation of the grid. As the grid decarbonises solar PV will gradually have a lower impact on reducing a school's carbon emissions, but conversely the school's carbon emissions from grid consumption will be lower.
