Arvalee Special school caters for children aged 3 to 19 years with moderate and severe learning difficulties. The single-storey, purpose built school is made up of four distinct pods which house specialist facilities including sensory therapy rooms and courtyards, hygiene and hoisting facilities, and specialist teaching areas for art, technology, design and home economics.
This school caters for the special educational needs of pupils in the Omagh and surrounding areas. It is the first of a planned six schools which will eventually comprise the “Lisanelly Shared Educational Campus.”
Heating to all the classroom areas uses embedded UFH with each manifold having its own dedicated BMS control panel. Communal areas such as Dining Room and Multi-Function/Sports Hall have dedicated air handling units in addition to UFH to enable fast temperature reaction times. Heat is generated by Viessmann Vitrotronic oil fired run and standby boilers which incorporate flue gas to hot water heat exchangers for optimum heat recovery. When natural gas becomes available the boilers can readily be converted to run on this medium. All circulating pumps are duty/standby arrangement and incorporate VSD drive mechanisms.
Water supplies, with the exception of WC’s, are provided by a 3 stage boosted water pump supplied by a potable water tank located in the boilerhouse. Water supplies to WC’s site wide is provided from a rainwater harvesting tank located externally underground. In the event of low water levels within this tank an automatic mains water top up system is installed.
All WC’s and WHB’s site wide are fitted with solenoid valves which operate on an occupancy PIR sensor. Thermostatic mixing valves are fitted to all WHB’s and sinks throughout the school. Flow limiting devices have also been fitted at all hot, cold and mains water outlets to minimise water usage. Air conditioning has been fitted in all resource communal areas to maximise pupil comfort and each classroom has been fitted with heat recovery ventilation systems.
LPG gas has been installed to cater for Kitchen and Home Economics requirements each incorporating gas proving and isolation facilities. Future availability of natural gas has been catered for, both internally and externally, by sizing pipework for such eventuality.
“State of the Art” BMS control systems have been installed site wide with emphasis placed on “ease of use” for the end user.
The project was a “BREEAM” Excellent.
Jonathan Gray, the principal said “It’s a lovely, state-of-the art building, and we are all absolutely thrilled to get into it. It’s just wonderful to get the school up and running for the children in the Omagh area. We’re very pleased with it.”
