Chafyn Grove School, an independent day and boarding preparatory school in Salisbury, has more than halved its annual costs for gas and electricity. Founded in 1879 as an all-boys' school, today, from its 5-hectare site, the school provides education to day, weekly and full-board pupils aged from 3 to 13.
Energy efficiency and better user comfort
Chafyn Grove has an excellent track record. In the past three years its children have won 43 scholarships and awards to senior schools. Ensuring outstanding results, however, has to be underpinned by a comfortable learning environment, something that the school was keen to start improving around five years ago in the knowledge that the latest BMS technology would also help reduce its carbon footprint and introduce greater levels of energy efficiency.
“The main reason for the BMS upgrade was to renew inefficient boiler controls, to give better user comfort and reduce gas usage,” states Toby White, Estates Bursar, Health and Safety Officer at Chafyn Grove School. “We reached out to local company Novac Control Systems and they recommended Priva Blue ID.”
“Previously, we had 10 separate gas meters servicing 10 separate buildings,” explains Mr White. “Since July 2013, six of these have been upgraded with Priva controls. We still have more buildings to upgrade, but they are smaller and use less gas, so the priority is lower.”
Impressive energy savings
The results of the upgrade to date have been extremely impressive, with gas and electricity consumption, and overall energy bills, reduced considerably. With regard to gas, usage has reduced from 6,500 kWh/heating degree days in 2012-13, to 4,400 in 2016-17, a 32% reduction. Indeed, the school is on track to improve this percentage even further in 2017-18.
In terms of combined gas and electricity consumption, Chafyn Grove has witnessed 38% reduction. Perhaps most impressively of all, with respect to financial savings, the school has seen a reduction from £55,000 per annum, to £27,000 in the period from 2013 to 2017.
“Yes, gas, electricity and waste disposal have all been reduced,” concludes Mr White. “The figures speak for themselves; we are very happy.”
