Analyse your school energy use - heating timings

10 Investigating energy usage KS1, KS2, KS3, KS4, KS5

Activity summary


One of the easiest ways to save your school money and reduce its carbon footprint is to make sure you're only heating the school when it needs to be warm!  There is no need to heat schools on weekends or holidays if no one is in!

Have a look at the following two graphs of Energy Sparks school's gas consumption and see if you can answer the following questions.

Graph A.  L High School
L High School gas consumption

A1. When do you think people are in the school buildings?
A2. At what time(s) is gas consumption high (over £6)
A3. What is the boiler doing when the school is closed?
A4. Are there any questions you need to ask other people about this data (think about who is using the school and when)?
A5. Do you think this boiler is working effectively?  Why or why not?


Graph B.  SP Primary School

SP Primary School gas consumption



B1. When do you think people are in the school buildings?
B2. At what time(s) is gas consumption high (over £6)
B3. What is the boiler doing when the school is closed?
B4. Are there any questions you need to ask other people about this data (think about who is using the school and when)?
B5. Do you think this boiler is working effectively?  Why or why not?


C1. Which school has a better heating management system?  
C2. If you were an Energy Analyst, what recommendations would you make for L High school.  
C3. Could you make any recommendations for SP Primary School?


* Degree days (the black line) is a measure of how much the boiler has to work to maintain a suitable temperature.  It's a bit like a reverse temperature.  The lower the degree day reading, the warmer the temperature at that time.
