Mechanical and electrical upgrades included the installation of the following:
- LED lighting system with occupancy and daylight control
- 4 kWp Solar PV system
- time controls on water heaters
- new high-efficiency gas boilers, insulation of pipework and new building management system
About the programme
This energy upgrade was delivered through the Pathfinder programme in collaboration with the Department of Education. This programme is paving the way for a national programme for the energy retrofit of schools built before 2008.
The Schools Energy Retrofit Pathfinder programme is funded by the Department of Education and Department of the Environment, Climate and Communications. The programme is administered by the Planning and Building Unit in the Department of Education with their delivery partner Limerick Clare ETB. and the Sustainable Energy Authority of Ireland.
