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.

Quality of thermostatic control

This is HTML content

Energy Sparks calculates how good a school's thermostatic control is by calculating a measure called 'R2'. The heating consumption of a school should be linearly proportional to the outside temperature, the colder it is the more energy is required to keep the school warm. The 'R2' is a measure of how well correlated this heating consumption is with outside temperature - the closer to 1.0 the better the control. Any value above 0.8 is good. If a school has a value below 0.5 it suggests the thermostatic control is very poor and there is a limited relationship between the temperature and the heating used to keep the school warm.

There can be many reasons for this control being poor:

Poor thermostat control can make a school an uncomfortable place to inhabit and expensive to run. It also means a school will see less benefit in installing insulation if the heating consumption has little relationship to outside temperature and therefore heat loss.

If a school's thermostatic control is poor and want to improve it, please contact Energy Sparks and we would be happy to provide further advice.
