There were 430 non-domestic Building Energy Rating (BER) audits reported in quarter two 2020 compared with 1,095 in quarter two 2019 (see Table A, Table 1 and Figure 1). This is a decrease of 61% (see Information Note). April 2020 was 65% lower than April 2019. May 2020 was 75% below May 2019. There was a decrease in June 2020 when the number of completed non-domestic BER audits was 38% below the number in June 2019.

Building Energy Ratings (BER) audits were conducted for 1,623 non-domestic buildings constructed between 2015 and 2020 (see Table 13). Over one fifth (21%) of these buildings received an “A” rating compared with 8% of non-domestic buildings constructed during 2010 to 2014 (see Figure 4). In contrast, 97% of domestic dwellings constructed between 2015-2020 received an "A" rating (separate CSO release). 

There were 60,513 non-domestic BER audits conducted in the period 2009 to 2020 (see Table 1). The profile of non-domestic BER audits conducted since 2009 was 1% awarded an "A" rating, 14% a "B" rating, and 34% with a “C” rating (see Table 3).

The most energy efficient building types audited during 2009-2020 were Schools and colleges with 25% awarded an “A” rating (see Table 3). The second most energy efficient buildings were Nursing residential homes and hostels with 8% rated “A”. The least energy efficient building types, defined by a “G” rating, were Workshops and maintenance depots (23%) followed by Other Buildings (20%) (see Figure 3).

The highest proportion of combined “A” and “B” ratings was in County Carlow at 21% (see Table 4). Kilkenny had the highest proportion of “G” rated buildings at 18% (see Table 4).

In Dublin city, Dublin 15 had the highest proportion of combined “A” and “B” ratings at 26% followed by 20% for Dublin 18 (see Table 5). The highest proportion of “G” ratings was 17% in Dublin 5, Dublin 6W and Dublin 8 (see Table 5).

The average floor area of all audited non-domestic dwellings was 681 square metres (see Table 10). This average size varied from 3,261 square metres for hotels to 296 square metres for Restaurants and public houses.

BER certificates expire after ten years unless a new audit has been undertaken. This means that many of the 2009 certificates expired in 2019. The CSO has included these expired certificates in this release. The period of construction is not yet available for audits undertaken in 2020. This information will be added to the next statistical release.
