Saving Energy In Schools
Okehampton College - Devon
What is Okehampton College doing to minimise energy losses in energy transformations?
• BTEC Level 2 Applied Science
• Energy and Our Universe
• Task 4

Building Management System

Steps Being Taken
• Ask people to use less energy / be less wasteful.
• 3,000 efficient lights (T5 conversions) fitted.
• Increased levels of insulation.
• More efficient gas boilers fitted
• Moved radiators about .
• Installation of renewable energy systems.
• Smart metering / better diagnostics.
• Formation of staff/student energy groups.
5
People – behaviour change
• People make the most difference
T5 Fluorescent tubes – 3,000 fitted
6
T5 lights produce more light and less heat meaning that less electricity is needed to produce the required light.
More efficient – they use 50% less electricity but produce 20% more light than conventional fluorescent tubes.
Increased insulation
• Cavity wall and loft insulation added.
• This contains trapped air which reduces heat loss.
• Less energy is then needed to heat the building.
7
More efficient boilers
• More efficient central heating boilers fitted meaning that a higher % of heat gets delivered to the building instead of going up the chimney.
• Flow temperature compensation – as the building warms up the temperature of the water in the radiators drops. This stops the rooms being overheated which saves gas.
• Both of these measures result in less gas being burnt so leading to less atmospheric emissions.
8
Move Radiators
• Take radiators out of the hot rooms and put them in the cold rooms.
• Evens out the heat demand – stops people letting excess heat out of the window.
9
Renewable Energy Systems
• Solar PV & soon wind turbines (small scale).
• Generation of your own electricity makes you use it more wisely and less fossil fuel energy is needed – an environmental benefit.

Monitoring what we use…

Does it Work….• Annual savings of around £25,000 on electricity already.
• Within a year additional measures should eliminate the electricity bill.
• Gas consumption should fall sharply in the next year due to smart metering and more efficient boilers.
• The energy bill was £120,000 but soon it could be just £30,000
• But people using energy wisely makes the most difference.
• 1 person wasting 1p an hour will waste £100 in a year.
• 100 people doing this will waste £10,000 in a year.
