This section gives a more detailed analysis of how your school’s gas consumption has changed recently. It can be particularly useful if trying to investigate a change in gas consumption or monitoring the impact of action taken in the school.
The following sections provide more background and analysis on your gas baseload

In a school with a heating system that is working well (good boiler, good pipework for heat distribution, large enough radiators, and reasonable insulation), you might expect the heating to turn on at about 6am, and peak for the next 2 hours while the school is being heated up, and then gradually reduce during the day. In most schools the heat generated by electrical equipment and 30 pupils in a classroom would suggest classrooms need very little additional heating from the school's boiler, once the pupils arrive.
If the boiler has 'optimal start control' configured, you might notice the start time of the boiler changing automatically ‐ from perhaps 6:30am in milder weather to earlier e.g. 4:30pm in colder weather. In very cold weather you might notice the heating coming on 'at random' - this is most likely frost protection - the boiler turning the heating system on to stop the school's pipework freezing.
The chart automatically uses the seven most recently available days. Use the explore buttons above the chart to compare alternative days. You can click on the legend to add or remove lines from the graph to make it clearer.
You can use this type of chart to understand how the school's gas use varies throughout the week.
Degree days are the inverse of temperature. The higher the degree days the lower the temperature. See a more detailed explanation. If the heating boiler is working well at your school, degree days should track the gas usage quite closely.
