Instituting energy efficiency measures in public sector buildings could save the taxpayer up to €100m in two to three years, according a report by Dublin Friends of the Earth (DFOE).

The ‘Through the Roof’ report shows that only one in five public buildings in Ireland have Display Energy Certificates (DECs).  Public buildings with a floor area greater than 1,000m2 are legally required to have a DEC since 1 January 2009. This equates to approximately 5,000 public buildings in Ireland.
