This chapter looks at data from the quarterly release, “Domestic Building Energy Ratings”, published by the CSO and based on data from the Sustainable Energy Authority of Ireland Building Energy Rating (BER) scheme.
The chapter also contains statistics on aspects of Ireland’s Environmental Economy. The data on Environment Taxes and Economy-Wide Material Flow Accounts are compiled by the CSO in accordance with Eurostat requirements set out in Regulation (EU) No. 691/2011.

5.1 shows the general impact of the age of the dwelling on the BER profile. It can be linked with changes to the Building Regulations that require new homes to be more energy efficient. The table includes the latest BER published for each dwelling from January 2009 to June 2015. There has been a dramatic improvement in the BER for domestic dwellings built in recent years. A BER rating of A was given to 40% and a rating of B to 53% of audited dwellings that were constructed during 2010-2015. This is a huge improvement compared with the energy performance of dwellings constructed in 2005-2009 where only 1% received an A rating and 36% a B rating.

The volume of total domestic extraction in 2012 at 77.2 million tonnes decreased by 10.8% compared with a figure of 86.5 million tonnes in 2011. This was mainly driven by the fall in domestic extraction of non-metallic minerals by 15.8% from 40.6 million tonnes in 2011 to 34.2 million tonnes in 2012 and reflects a decrease in construction activity over this period. The remaining components of domestic extraction in 2012 were biomass at 36.7 million tonnes, metallic minerals at 4.2 million tonnes and fossil fuels at 2.1 million tonnes.
Trade exports of materials in 2012 amounted to 16.4 million tonnes compared with 34.7 million tonnes of imports. Fossil Fuels (at 15.0 million tonnes) were the largest import category in 2012.
Total emissions increased from 52.4 million tonnes in 2011 to 52.6 million tonnes in 2012.
