The hidden costs of school energy inefficiency

Cost-cutting measures at school often focus on salaries and supplies - overlooking a significant cost.

When discussing the operational costs of schools, we often focus on visible expenses such as salaries and supplies. However, one significant cost is often overlooked - energy inefficiency. In many buildings, including schools, energy consumption continues even when the premises are unoccupied. This wasteful practice is a direct consequence of budget cuts that have led to a reduction in the quality of personnel managing our educational facilities. But what if we could change this? What if our buildings could intelligently manage energy use, automatically switching off on non-school days or reducing consumption once the school day ends? This is not a far-fetched idea; it is a reality that is unfolding now.

The benefits of energy efficiency in schools

Investing in energy efficiency measures in schools can lead to significant benefits. Schools that have invested in energy efficiency measures are seeing substantial savings within the first year, equating to almost 100 tonnes of CO2 equivalent (CO2e). These savings not only translate into financial benefits but also contribute to reducing our environmental impact. The money saved from energy efficiency measures can be allocated towards other important aspects of education, such as hiring quality teachers, improving air handling systems for better cognitive performance, or investing in educational resources.

To put the impact of these savings into perspective, 100 tonnes of CO2e is equivalent to approximately 4,545 trees needed to remove that amount of CO2 from the atmosphere. This represents a land area of approximately 0.045 square kilometers. When considering the bigger picture, with approximately 32,000 schools in the UK, if each of these schools could reduce their CO2e by 100 tonnes, we would see a total reduction of 3,200,000 tonnes. This would require approximately 145 million trees planted over an area of about 1,455 square kilometers, which is roughly 4.66% of the UK's total woodland area.

Financial savings through energy efficiency

In addition to the environmental benefits, investing in energy efficiency measures can also result in substantial financial savings for schools. If each school could save £50,000 per year through energy efficiency measures, the total savings would amount to a staggering £1.6 billion per year. This significant amount could be reinvested into our education system, improving the quality of education and the school environment for our children.

The impact of energy efficiency in schools

Energy efficiency measures in schools not only result in financial savings but also have a positive impact on the overall learning environment. By reducing energy wastage, schools can create a more comfortable and conducive atmosphere for students and teachers. Temperature control systems can be optimized to ensure the right level of warmth during school hours, while minimizing energy consumption during non-school hours. This not only contributes to a better learning experience but also promotes sustainability and responsible energy use among students.

The role of technology in energy efficiency

Advancements in technology, such as artificial intelligence (AI) and smart building management systems, play a crucial role in optimizing energy efficiency in schools. These systems can intelligently monitor and control energy usage, automatically adjusting settings based on occupancy and usage patterns. For example, lights and HVAC systems can be programmed to turn off when classrooms are unoccupied or adjust temperature settings based on occupancy levels. This level of automation ensures that energy is not wasted when it is not needed, resulting in significant savings and reduced environmental impact.

Case studies: realising the benefits

Several schools have already embraced energy efficiency measures via Novacene and are reaping benefits. For example, East Renfrewshire Council identified energy savings in many of its schools, including an annual reduction of 100 tonnes of CO2e per school. Reinvesting these significant savings creates opportunities for schools to: hire additional teaching staff, reduce class sizes and provide a better learning experience for students. Similarly, any school can adjust lighting and HVAC settings, resulting in a minimum of 20% reduction in energy consumption and savings. These success stories showcase the tangible benefits of investing in energy efficiency measures in schools.

Government Initiatives and Support

Recognising the importance of energy efficiency in schools, the government has implemented various initiatives and support programs. These programs provide funding and resources to help schools implement energy efficiency measures and reduce their carbon footprint. Schools can access grants, subsidies, and expert guidance to identify areas for improvement and implement energy-saving solutions. By taking advantage of these initiatives, schools can not only save money but also contribute to the national goal of reducing carbon emissions and promoting sustainability.


The hidden costs of energy inefficiency in schools go beyond financial implications. They have a significant impact on the environment and the overall quality of education. By investing in energy-efficient buildings and implementing smart energy management systems, schools can reduce their carbon footprint, save money, and create a better learning environment for students. Government initiatives and support further facilitate the adoption of energy efficiency measures in schools.

It is time to prioritise these investments and ensure a sustainable future for our children. Let us invest in energy efficiency today for a brighter tomorrow.
