Gold Star for Energy Savings!

A new boiler, roof insulation and double-glazing and has helped Wren House Nursery School in Eastbourne reduce energy bills by £515 per year.

The nursery received a free energy audit through the Energy Efficient East Sussex programme, after which they were awarded a grant of £1,000 towards the new boiler. The programme is funded by East Sussex County Council and the EU, to help local businesses improve profitability and reduce their carbon footprint.

OutsideSoon after the audit, the flat roof of the nursery was badly damaged during stormy weather. Owner Richard Winton explained, “We looked for the opportunity in a bad situation. Installing a new roof allowed us to increase insulation levels, and whilst the nursery was closed it was a sensible time to upgrade the windows.”

The Carbon Trust state that a building can typically can lose 22% of its heat through an uninsulated roof. Insulating to a u-value of 0.18 W/m2/K, as per modern building standards, has reduced energy usage at the nursery by over 3,000 kWh per year.

Double glazing has saved an additional 1,675 kWh, from both reducing direct heat loss through the glass and eliminating draughts. Whilst the initial outlay required means that payback period for double-glazing through energy cost savings alone is relatively lengthy, the measure provides a number of additional benefits, including improved sound proofing and security.

Wren-House-Nursery-BoilerBuilding fabric improved, Wren House Nursery School upgraded their heating system to further reduce gas consumption. Replacing their ageing 65% efficient boiler with a modern 90% condensing model has reduced annual gas usage by 3,700 kWh, saving £190 per year.

Richard is pleased with the upgrades, “It’s been great to have been able to lower energy costs, whilst at the same time improve the building for the nursery users and reduce our carbon footprint.”

Energy Efficient East Sussex helped SMEs reduce annual greenhouse gas emissions by over 150 tonnes. It was delivered by the Sustainable Business Partnership CIC.
