CSO statistical publication, , 11am

Key Findings

  • Of the non-domestic buildings audited for a Building Energy Rating (BER) since 2009, 3% received an A rating, 14% a B rating, and 33% a C rating (See Figure 3 and Table 3).

  • A ratings were awarded to 44% of non-domestic buildings constructed between 2020 and 2024, a higher proportion than for construction periods 2015-2019 (21%) and 2010-2014 (6%) (See Figure 2 and Table 13).

  • The number of audits reported in January to March (Q1) 2024 was 16% more than in Q1 2023 (See Figure 1 and Table A).

  • The most energy efficient building types audited from 2009-2024 were Schools & Colleges, with 46% receiving an A rating (See Figure 4 and Table 3).

  • The highest proportion of A ratings by county was in County Kildare (5%), while  County Kilkenny, County Sligo, and Limerick City had the highest proportions of G rated buildings at 16% each (See Table 4).

Statistician's Comment

The Central Statistics Office (CSO) has today (18 April 2024) released Non-Domestic Building Energy Ratings for Quarter 1 (Q1) 2024.

Commenting on the release, Kevin Hunt, Statistician in the Climate and Energy Division, said: "The number of non-domestic Building Energy Rating (BER) audits reported in January to March (Q1) 2024 was 1,271. This was 16% higher than the 1,098 audits reported in Q1 2023. In total there were 75,342 non-domestic BER audits reported for the period 2009 to 2024 (See Table 1). This figure includes multiple audits for some buildings.

Including only the most recent audit for each building, 73,860 non-domestic buildings have received a BER since 2009 (See Table 2). Of these, 3% received an A rating in their most recent audit, 14% a B rating, and 33% a C rating (See Figure 3 and Table 3).

Period of Construction

BER audits have been conducted for 2,313 non-domestic buildings constructed between 2020 and 2024. A ratings were given to 44% of these buildings, compared with 21% of the 1,654 BERs received by buildings constructed from 2015 to 2019, and 6% of those built from 2010 to 2014 (See Table 13).

Building Type

The most energy efficient non-domestic building types audited during 2009-2024 were Schools & Colleges, with 46% receiving an A rating. The second most energy efficient buildings were Nursing Residential Homes & Hostels, with 13% rated A. The least energy efficient building types, defined by the highest proportion of G ratings, were Workshops & Maintenance Depots (23%) (See Figure 4 and Table 3).

Local Area Analysis

The highest proportion of A ratings by county was in County Kildare (5%). County Kilkenny, County Sligo, and Limerick City had the highest proportions of G rated buildings at 16% each (See Table 4). Among Dublin postal districts, the highest proportion of A ratings were in Dublin 20 (8%) and Dublin 16 (6%), while the highest proportion of G ratings was 17% for each of Dublin 3, Dublin 5, Dublin 6W, and Dublin 8 (See Table 5).

Floor Area

The average floor area for all audited non-domestic buildings was 710 square metres. The building type with the largest average floor area was Hotels (3,166 square metres) while the smallest was Restaurants & Public Houses (287 square metres) (See Table 10)."

Editor's Note

BER certificates expire after 10 years unless a new audit has been undertaken. This means that certificates from more than 10 years ago have expired if they were not updated. The CSO has included these expired certificates in this release in order to have a more representative analysis of energy efficiency in the non-domestic sector. Provisional BER certificates for buildings that are incomplete or not yet constructed have been excluded from this release. This exclusion also applies to new Shell and Core Buildings, which are rated and sold as bare structures before being fully fitted.
