How Schools Waste Heating Energy (and How to Fix It)
INTRO
Most schools waste a significant amount of energy through heating systems running when buildings are unoccupied, poorly configured schedules and limited visibility across sites. By identifying these inefficiencies and improving control, schools can typically reduce energy consumption by 15–30% without impacting comfort.
THE BIGGEST SOURCE OF ENERGY WASTE IN SCHOOLS
The largest contributor to wasted energy in schools is heating.
Heating often accounts for the majority of a school’s energy spend, yet it is frequently:
Running outside of school hours
Not aligned to actual occupancy
Controlled manually or inconsistently
Applied uniformly across all areas
This results in large amounts of unnecessary energy use that often goes unnoticed.
TYPICAL HEATING WASTE IN SCHOOLS
15–30% potential energy reduction
Heating is the largest driver of energy spend
Waste often occurs outside occupied hours
Issues can be identified within weeks
5 COMMON WAYS SCHOOLS WASTE HEATING ENERGY
1. Heating Empty Classrooms
Heating systems often operate on fixed schedules rather than real occupancy.
This leads to classrooms being heated:
Early in the morning before use
Late into the evening
During weekends
2. Out-of-Hours and Holiday Usage
Many schools continue heating buildings during:
School holidays
Half terms
Weekends
Without central visibility, these issues can persist for long periods.
3. Poorly Configured Heating Controls
Legacy systems or poorly set controls can result in:
Overheating
Inconsistent temperatures
Heating running longer than required
4. Lack of Visibility Across Buildings
Multi-site schools and MATs often lack a clear view of:
Which buildings are consuming the most energy
When heating is running unnecessarily
Where inefficiencies exist
5. Heating All Areas Equally
Not all spaces are used the same way.
However, many systems:
Heat all rooms to the same level
Ignore occupancy patterns
Fail to adapt to usage
SUPPORTING CIF FUNDING APPLICATIONS
Energenie Solutions helps schools build stronger CIF applications by providing:
Clear evidence of energy waste and inefficiency
Quantified savings potential

HOW TO REDUCE HEATING ENERGY IN SCHOOLS
Reducing heating waste does not require replacing entire systems. It requires better visibility and smarter control.
Step 1: Monitor Building Performance
Track key data points including:
Temperature
Energy usage
Occupancy
Environmental conditions
Step 2: Identify Waste
Use data to uncover:
Out-of-hours heating
Overheated spaces
Inefficient schedules
Step 3: Optimise Heating Control
Adjust systems to:
Align heating with occupancy
Reduce runtime
Eliminate unnecessary usage
Step 4: Measure and Improve
Continuously track:
Energy savings
Performance improvements
Carbon impact

FAQ
What is the biggest cause of heating waste in schools?
Out-of-hours heating is typically the largest contributor, including evenings, weekends and holidays.
Can schools reduce energy costs without replacing systems?
Yes. Many savings come from improving control and visibility rather than full system replacement.
How quickly can savings be identified?
In many cases, inefficiencies can be identified within weeks of monitoring.
Does this work across multiple school sites?
Yes. Multi-site visibility is one of the key benefits of using a centralised system.
How much energy do schools typically waste?
Studies suggest schools can waste 15–25% of energy due to inefficiencies such as poor scheduling and lack of control.
What is the biggest source of energy waste in schools?
The biggest source is typically heating running outside of occupied hours, including evenings, weekends and holidays.
