Department of Public Expenditure and Reform
Lighting is not metered separately in the vast majority of public buildings. For this reason it is only possible to provide an estimate for the amount spent on lighting. The OPW is responsible for buildings occupied by central Government Departments and some state agencies. The total annual energy expenditure in these buildings is estimated at €32M. Approximately 65% of this is on electricity. It is estimated that lighting accounts for 40%-50% of electricity in office and similar type buildings. Based on these assumptions, the estimated expenditure on lighting in OPW buildings is €8.3M - €10.4M. There are no figures available for the cost of lighting in the wider public sector.
