Back to School: Top 5 Energy Efficiency Measures for Schools and Colleges

As schools and colleges return for a new academic year, there’s a renewed opportunity to rethink how energy is used across the campus. Rising energy costs and the drive towards Net Zero mean education providers need to look carefully at efficiency measures—not only to reduce carbon footprints but also to create healthier, more engaging learning environments for staff and students.

Here are five practical steps that schools and colleges can take this year:

1. Smarter Heating and Cooling

Heating often makes up the largest share of a school’s energy bill. Installing smart controls, zoning classrooms, and setting realistic temperature targets (around 19–20°C in classrooms) can reduce waste without compromising comfort. Adding insulation to older buildings and maintaining boilers or heat pumps ensures they run efficiently throughout the year.

Carbon impact: Lower fuel consumption directly reduces Scope 1 emissions.
Student benefit: More consistent, comfortable learning spaces.

2. LED Lighting and Controls

Lighting can account for 20–30% of school electricity use. Replacing fluorescent tubes with LED lights cuts electricity use by up to 50%. Adding motion sensors, daylight controls, and timed systems ensures lights aren’t left on in empty rooms or corridors.

Carbon impact: Reduces Scope 2 electricity-related emissions.
Student benefit: Better quality lighting improves concentration and wellbeing.

3. Renewable Energy On-Site

Solar PV panels are increasingly affordable and can generate electricity directly on campus. Even partial coverage on roofs can make a noticeable difference, especially when combined with battery storage. Some schools are even using renewables as teaching tools, integrating real-time energy dashboards into science and geography classes.

Carbon impact: Cuts grid electricity demand and Scope 2 emissions.
Student benefit: Builds awareness of sustainability and offers hands-on learning opportunities.

4. Behaviour and Awareness Campaigns

Technology alone won’t deliver results. Schools that run regular energy awareness campaigns—“Switch It Off” challenges, classroom energy monitors, or student “eco teams”—see real changes in behaviour. When staff and students feel ownership of sustainability, savings are bigger and longer-lasting.

Carbon impact: Multiplies the effect of physical measures across all energy use.
Student benefit: Teaches responsibility, teamwork, and climate literacy.

5. Greener Transport Choices

Encouraging walking, cycling, public transport, and car-sharing reduces transport-related emissions. Providing secure cycle storage and even charging hubs for e-bikes makes active travel safer and more practical. This also reduces congestion around school gates, making drop-off and pick-up safer for students.

Carbon impact: Reduces Scope 3 commuting-related emissions.
Student benefit: Healthier, more active lifestyles and cleaner air around schools.

Final Thought

Schools and colleges are more than just places of education—they’re hubs of community influence. By taking visible, practical steps to reduce energy use and carbon emissions, they set an example for future generations and create a better daily experience for staff and students alike.

The start of a new academic year is the perfect time to make small changes that add up to big impacts.
