    For Kildare County Council, ORS has worked on a range of different projects, from fire stations to council buildings to challenging projects such as converting a church in Athy into a municipal library. The former church was converted into a state-of-the-art library and auditorium for the local community as a landmark project jointly funded by Kildare County Council and the Irish Government, with ORS on board as the energy auditor and consultant. It was the first public sector project that was given EXEED Certification by the Sustainable Energy Authority of Ireland.
