The current policy of the OPW with regards to energy criteria for new buildings is to specify a maximum energy performance target of 120kWh/m2 year for standard office accommodation. This target would be considered best practice for this type of building. Other types of building would require individual targets dependant on function and purpose. In the present leased market it is not practical to set a similar type of target and so buildings acquired by lease or existing buildings that are being purchased are not set such an energy target.
As part of the National Climate Change Strategy, the OPW is committed to converting a number of the heating systems in existing buildings to Biomass. This programme of work is underway and is due for completion before the next heating season. Although this is not specifically an energy efficiency measure it will reduce the carbon footprint.
Energy efficiency is considered in the refurbishment of existing accommodation and where economically practical improvements are incorporated into the works to maximise energy performance.
An essential part of the OPW's Staff Energy Awareness Campaign, which is currently underway, is a preliminary energy audit in each of the targeted buildings. It is anticipated that these energy audits will identify areas for improvement in the energy performance in certain buildings and improvement works will be considered when these audits have been completed.
