If air conditioning systems leak, the refrigerants can be thousands of times more harmful to the ozone layer than carbon dioxide. That’s why staying on top of TM44 Air Conditioning Inspections is so important – not just for compliance but for cutting costs and reducing your impact on the planet.

What you need to know

Westbrook Lane Primary School in Leeds relied on three split air conditioning systems to cool critical areas such as the library, IT room, and a classroom. With rising electricity prices, the school needed a cost-effective solution to evaluate its energy use while ensuring compliance with TM44 Air Conditioning regulations.

What Westbrook Lane Primary School thought

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."

Westbrook Lane Primary School

Why it matters

Zenergi carried out a comprehensive TM44 inspection, evaluating the school’s 26.8kW combined cooling capacity to ensure full compliance. One of our accredited assessors reviewed all aspects of the air conditioning systems, including cooling plants, terminal points, system controls and maintenance practices.

Following the inspection, we went beyond compliance by delivering a detailed energy efficiency report. This report highlighted 25 tailored recommendations, providing the school with clear, actionable steps to:

  • Optimise system performance
  • Reduce unnecessary energy consumption
  • Lower operating costs

What we think

Westbrook Lane Primary School’s inspection uncovered 25 actionable recommendations to improve system efficiency. By acting on the largest opportunity alone, the school could save 50% on annual operating costs while dramatically reducing its environmental impact."
