A school estate running on a third of the lighting energy it used

A public school has the same estate problem as an independent one and less room to solve it. Classrooms, halls, admin blocks, sports facilities and external lighting all age together, and the funding to replace them arrives in increments that are too small to do the job properly.

That produces the pattern every school knows: lamp-for-lamp replacement, year after year, on fittings that were inefficient when they were installed. Each replacement is affordable and none of them changes the electricity account.

Meanwhile the school pays for the inefficiency every month, out of the same budget that funds everything else it does.

The estate was converted as a whole rather than in the increments the maintenance budget would have allowed, which is the decision that made the difference. A full-facility conversion captures the long-hours areas that an incremental programme never reaches, because incremental replacement follows failures and failures happen where fittings are switched most, not where they run longest.

At an estimated 18-month payback, the conversion is funded by the saving inside two academic years. From year three the reduction is money the school keeps.

The released demand of an estimated 41 kVA is capacity available for anything the school adds later, from a computer facility to sports lighting, without a supply upgrade application.
