What you did

The Ecoclub have investigated the spend on Gas when the school is closed, last year Oasis Immingham spent £17,289 on Gas when the school has been closed. The community clubs have also contributed to the gas usage over the Winter months. Site staff and the line manager for Ecoclub have been emailed to see if there are ways that we can reduce this for next year. The amount spent on closed school days has been discussed with the Regional Area Director and the schools ALT team to discuss ways to reduce this for next year. The Ecoclub will be monitoring ways in which it can be reduced and how much is being spent. The Ecoclub have created posters to encourage the school switch off on holidays and weekends to reduce this 

Activity description

Do you know how many hours your school is open in one year?  How about how many hours it's closed and empty?

For most schools the opening hours, even including teacher's prep time and maintenance staff working before and after school, barely reach 2000 hours.  The hours when your school is closed however number almost 7000 hours.  If your school is being heated for all of that time, your school will be wasting a lot of energy!

Background information

  1. Gas is the most common energy source for heating in schools, although some schools use electricity or oil for heating. A gas boiler works by burning gas to heat up water, which is then pumped around the school to heat up the radiators.

  2. This pie chart shows you how much gas your school uses at different times. For most schools there should be no gas use in the school holidays. The only reason gas might be used is to protect the pipes from freezing in very cold weather. 
  3. By getting rid of holiday gas use at your school, how much could you save?

  4. The red bars on this chart show the gas used during holiday weeks. In which holidays is the most gas used? Does your school remember to turn off the heating in some holidays but not in others?

What can you do?

  1. Talk to the school caretaker or head teacher about turning the heating and hot water off during the school holidays. You could write them a letter telling them how much the school could save if it turned off its heating and hot water in the  holidays.
  2. If someone is working in the school in the holidays it is usually more efficient just to heat that room with a fan heater or other small electric heater than the whole school.
  3. Sometimes the caretaker is concerned about the school getting too cold and the pipes freezing. This is a very rare event, and because most school boilers can be programmed to automatically turn on in very cold weather (called 'frost protection') it is unnecessary to leave the boiler on all holiday. If the school boiler doesn't have automatic 'frost protection' then the thermostat (that tells the heating when to come on) should be turned down as low as possible to 8°C - this will save 70% of the gas compared with leaving the thermostat at 20°C.
