If your school’s air conditioning system has a combined cooling capacity of over 12kW, you’re legally required to comply with TM44 regulations.

 

What you need to know

Cheam Fields Primary Academy in Sutton, part of the LEO Academy Trust, has 11 air conditioning units serving classrooms, the kitchen and staff room, server room, office and reception areas. Together, the combined cooling capacity of these units is 60.4 kW. This made compliance with TM44 regulations a must – as well as an opportunity for savings.

Our accredited assessor visited Cheam Fields Primary Academy to carry out an inspection of the air conditioning systems.

The inspection included a detailed review of system performance, identification of faults, and opportunities for energy savings. After the site survey, we produced the compliance certificate and lodged it with the central register.

But we didn’t stop there. Unlike standard TM44 inspections, we provide a supplementary energy report that’s easy to understand and highlights exactly how much money can be saved by implementing recommendations.

What Cheam Fields Primary Academy thought

This is excellent, I was really blown away by the detail and scope of the report. We are pleased to know that, not only are we compliant with the regulation, but that we can reduce our impact on the planet and make some significant annual cost savings too – many of which can be achieved at no cost to ourselves.

Why it matters

Air conditioning systems use chemicals called Hydrofluorocarbons (HFCs), which can be thousands of times more harmful to the environment than carbon dioxide if they leak.

Some HFCs are more than 13,000 times more harmful to the ozone layer, with the most commonly used typically 3,500 times more damaging. Therefore, maintaining compliance with TM44 inspections isn’t just important to avoid penalties, it protects the planet – and can save money too.

What we think

This project shows that compliance can uncover savings and reduce environmental impact. We identified simple, low-cost actions that cut energy use by over 25%. It’s a perfect example of how smart data and small changes can lead to big results.”

What difference it made

The TM44 assessment at Cheam Fields Primary Academy identified several practical no-cost and low cost recommendations for improving the efficiency of the air conditioning systems, including.

  • Correcting time schedules on controllers, saving £779.08 per year.
  • Adjusting temperature set points by 2°C, saving an additional £1,223.43 per year.
  • Identifying that 10 out of 11 units were oversized, with one offering 112% more cooling capacity than needed, with another at 97% and a third at 75%.
