How Westbrook Lane Primary School halved air conditioning system costs.

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.

The challenge

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.

Our solution

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

The results

The inspection identified significant opportunities for improvement, including:

• Cost savings: Halved operational costs, equating to £3,476 annually
• Efficiency gains: Enhanced Energy Efficiency Ratio (EER) of the system
• Compliance secured: TM44 certification registered and documented

More than just a legal requirement

For schools operating within tight budgets, cutting unnecessary energy costs isn’t just practical—it’s essential. Beyond the financial savings, improving air conditioning system efficiency also helps:

• Reduce carbon footprint: Decrease harmful refrigerant emissions
• Supports sustainability goals: Fosters a more environmentally-friendly approach to energy use
• Educates future generations: Leading by example, and demonstrating the importance of sustainability

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.

Here’s how Zenergi’s TM44 Inspection service made an impact:

• Identified £3,476 in annual savings from the largest opportunities
• Delivered 25 tailored recommendations for improving energy efficiency
• Simplified the path to compliance with clear, actionable reporting
• Included a supplementary energy report summarising all potential savings

Our TM44 Air Conditioning Inspection service delivers actionable results.

Westbrook Lane Primary School’s story proves that even small air conditioning systems can yield big savings. But halving operational costs isn’t just a win for your budget, it’s another small step towards a more sustainable future.
