Wellington School’s aging infrastructure was not designed with energy efficiency in mind. While the school had started modernising with condensing boilers and LED lighting, they needed expert guidance from the team at Zenergi, to uncover further opportunities to reduce energy consumption, costs and carbon emissions.

What you need to know

Zenergi conducted a comprehensive two-day energy audit to evaluate the school’s energy usage and identify cost-effective measures. The exercise aimed to reduce the school’s carbon emissions and operating costs while fostering sustainability.

By generating a project list of measures to strategically address inefficiencies, the school could significantly lower its environmental footprint and save on energy expenses.

What Wellington School thought

The energy audit has been a valuable starting point for our school’s sustainability journey, helping us identify and prioritise energy-saving opportunities. Zenergi’s high-quality report supports our leadership team and serves as a powerful learning tool for pupils, who are eager to engage in implementing new measures.

Why it matters

Wellington School could make an energy saving of 4.7% of current consumption leading to a reduction of £5,185 in energy costs and a carbon reduction of 15.4 tCO2e in exchange for a capital spend of £2,000 – offering a fast return on investment.

Opportunities included those with immediate ROI impact as well as medium to longer term saving benefits.

  • Low-cost and no-cost solutions: Improved heating management, reduced energy wastage and staff/student training.
  • Strategic upgrades: Repairing thermostatic valves and expanding LED lighting upgrades.

What we think

What really set this project apart was how the school involved its eco-committee in the programme. Wellington School recognises the importance of engaging the energy users of the future in the critical need to combat climate change and we were delighted to support the delivery of this message. After sharing the findings of our energy audit within a session to this group, they are now actively looking at current and future initiatives with insight and understanding."
