No, it is for the whole building. However, because we share the building, it has to be done on a floor basis. The Department is reliant on a shared heating system for the Government Buildings complex which is managed by the Houses of the Oireachtas. The current system uses a mix of gas and zero-emissions wood pellets. Heating costs are apportioned by floor area within the Government Buildings complex. At present the Department's energy use is effectively merged in with that of a number of other public bodies in the complex with no sub-metering of actual usage by individual Departments and operations. The energy costs are estimated for the coming year taking into account the previous expenditure.
