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.

Electricity out of hours use

This is HTML content

This chart shows the breakdown of when schools are using electricity - school day open: when the school is open to pupils and staff, school day closed: when the school is closed to pupils and staff overnight, weekends and evenings.

Most schools are unoccupied for about 85% of the year; between 5:00pm and 7:30am on school days, at weekends and during holidays. Focussing on reducing out of hours usage; turning appliances off, installing efficient appliances often provides schools with a cost-efficient way of reducing their overall consumption.

Schools should aim to reduce their out of hours usage below 25% of annual consumption. In comparing schools, it might be helpful for you to look at the 2 additional benchmarks on baseload (out of hours power consumption) that we provide as it might give you more information on a school's out of hours consumption.

This breakdown excludes electricity consumed by storage heaters and solar PV.
