The number of non-domestic BER audits performed in certain months have been adversely impacted by the COVID-19 pandemic. For further information please see the SEAI website.
There was an increase of 21% in the number of non-domestic BER audits reported in quarter two 2022 compared with quarter two 2021
The profile of non-domestic BER audits conducted since 2009 was 2% awarded an "A" rating, 13% a "B" rating, and 33% with a “C” rating
Over one-third (35%) of non-domestic buildings constructed between 2020 and 2022 received an “A” rating compared with 21% of non-domestic buildings constructed during 2015 to 2019
The most energy efficient building types audited during 2009-2022 were Schools and colleges with 34% awarded an “A” rating
The highest proportion of combined “A” and “B” ratings was in County Kildare at 22%
In Dublin city, Dublin 15 had the highest proportion of combined “A” and “B” ratings at 24%
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. Tables 13 and 14 have been updated to include a higher proportion of BER audits with a period of construction.
