Analyse your school energy use - when is your school occupied?

What you did

We have noticed that our energy consumption is very high at lunch time. This is unusually as most children are playing outside, so internal energy use should be reduced. Tomorrow, we are going to conduct a spot check around school to find out where energy is being used unnecessarily. 

We have also noticed that energy use is high in the hours following the school's closure. We believe that this is due to the cleaners' activities, such as using the vacuum. We have decided that we need to promote a 'tidy school' ethos amongst our classmates. This is because if we all take greater responsibility to keep our school clean, especially the carpets, the cleaners will not need to use the vacuum for quite as long.

Today we have also reviewed our Energy Reduction Action Plan. We feel that the points on our action plan are strong, though the action plan is clearly not yet having the desired effect as our energy use continues to remain high. We believe that we need to remind our classmates about this action plan and draw their attention to it. It is clearly displayed in each classroom, though we need to make sure that people are being reminded of it. We also need to promote it in a more positive way. For example, we need to help our classmates realise that it can save us money, meaning that there will be more money to spend on the things that we enjoy in school. 

Activity description

 
Contrary to popular opinion, teachers don't live in school.  Find out a bit more about when and how your school is occupied to understand when and how energy is being used in your school.  

Energy Sparks charts show your schools' energy consumption when the school is open (green) and closed (blue) on school days.
School A
School B

For good energy management, you want most of your energy use to be when the school is open.  Compare the following graphs showing the electricity use in two schools.   Which school is using most electricity in the early morning?  What time does the electricity use shoot up?  Can you think of a reason for this?  Is anyone in the school at this time?

 


School C
School D

Now look at School E.  When is most electricity being used?  Do you think this is anything to do with the school being occupied?
School E


This is the recent electricity data for your school:

We do not have enough data at the moment to display this chart
How did we calculate these figures?
 

We set open and closed times as a default but you can change this for your school when logged in as an Admin to your Energy Sparks account. Go to Manage School - Edit School times.  Design a questionnaire for staff to answer so that you can understand better what happens at the start and end of the school day.  You may want to ask the following questions: 

  • When do you arrive?
  • What appliances/ equipment do you switch on? (include lights, kettles, photocopiers, projectors, whiteboards, computers, printers, heaters/air con)
  • What time do you leave?

This is a very good opportunity for staff to think through their arrival and departure routines.  Do they need to be switching on equipment so early or turning it off so late?



Explanations
School C either has cleaners coming in very early in the morning or the electrical heating system warming up the school.
School D is a good representation of when school staff are coming in.
School E may have a late evening event taking place.  To understand more we would look at the graphs for the next few days.  If this pattern repeats we would want to investigate the timings of the electrical heating system or ask the Caretaker or an Energy Sparks auditor for more help understanding what is happening.
