Westbrook Lane Primary school in Leeds has three split air conditioning systems that serve its library, IT room, and a classroom. The school engaged Zenergi to evaluate its need to comply with TM44 Air Conditioning Inspections.
The survey identified 25 recommendations for improving the efficiency of the air conditioning systems.
The annual operational cost of the air conditioning system is £6,952, with the largest recommendation offering a saving of £3,476 (50%).
This case study demonstrates that even small air conditioning systems can offer significant financial savings.
Did you know? The refrigerant in all air conditioning systems is thousands of times more damaging to the ozone layer than Carbon Dioxide should it leak. This is why it is vitally important to maintain compliance with TM44.
Schools with air conditioning systems with an effective rated output of more than 12kW are legally required to ensure compliance with TM44 Air Conditioning Inspections. This includes systems consisting of individual units which are less than 12kW but whose combined effective rated output is more than 12kW.
A TM44 regulation inspection is where an accredited assessor is appointed to carry out an inspection of the air conditioning system. The assessment will review the efficiency of the system, check for faults, and provide advice on how to make it more efficient to reduce the costs involved in running it. Following the inspection, a full report will be provided detailing findings, faults, and recommendations. Inspections are required every five years to remain compliant.
The combined cooling capacity of the air conditioning system at Westbrook Lane Primary is 26.8kW which is over the 12kW qualification threshold required for legal compliance with TM44 regulations.
Following a comprehensive site survey, the compliance certificate and report were produced and lodged onto the central register. The survey assessed key questions set when inspecting the cooling plants, terminal points, system controls and maintenance. For Westbrook Lane Primary, this resulted in 25 recommendations for improving efficiency of the air conditioning systems.
The format and the method of presentation of the report is standard and set by the government. However, we believe that the output from the compliance report should go a lot further by providing customers with more valuable data. This is why our TM44 inspection service provides a supplementary energy report to provide the savings available for each of the recommendations identified in the report. The information is provided in a much more reader-friendly way so that it is easy to understand how much money each recommendation could save.
Key data for Westbrook Primary:
With the price of electricity increasing, any saving is vital to the school budget. Your energy report certainly provided us with clarity on how much our Air Conditioning systems cost us to run and where we can invest to make savings. Thank you.

Glenmorangie sought a focused solution to improve energy efficiency and reduce costs. By working closely with the team at Zenergi, the strategic building optimisation resulted in a 59% reduction in electricity consumption and a 52% reduction in gas usage.
Danes Educational Trust selected Zenergi as its trusted carbon reduction partner, securing £166,000 in grant funding for heat decarbonisation and energy efficiency upgrades.
Leigh Academies Trust adopted Zenergi’s Zen Flex Bespoke product to take advantage of market movements by purchasing a volume of energy up front, while also trading on the day-ahead market to spread the risk of the volatile markets.
Zenergi’s services for PR Associates keep schools up to date with energy compliance, as well as driving energy efficiency to reduce costs and carbon emissions.
Zenergi supports Shropshire Council’s vision to stabilise and progressively reduce its environmental footprint., with the provision of Display Energy Certificates, which it has carried out for the Council for over 10 years.
Zenergi carried out the delivery of commercial Energy Performance Certificates for 52 properties in Reading to meet compliance with the Minimum Energy Efficiency Standards.
School Business Professionals are increasingly challenged to balance shrinking budgets and escalating operating costs. However, energy is an area that offers opportunities to protect school budgets through a competitive tender process that proactively secures prices that take advantage of low wholesale market positions where possible.
We started working with Windmill Care when we successfully negotiated good tariffs for gas and electricity contracts for the group’s three care homes. But, before they went live, Windmill Care’s incumbent supplier identified a billing issue.
