This page visualises the Irish housing stock characterised by BER Rating. The BER rating is a measure of the energy performance of a building, with ratings ranging from
A1(most efficient) to
G (least efficient). The data is presented through charts showing the frequency of each rating, and the evolution of the national BER status over time. The charts are interactive allowing a filter by location, retrofit type, and dwelling type.
The IBSO uses these classifications:
BER RatingFollows standard rating system Retrofit Type- New Build - A dwelling is considered a new build if it was built on or after the year 2011.

- Requiring Retrofit - A dwelling is considered to require retrofit if it has an EPC rating below B2 and was built before 2011.

- Rural - Any location not within the Urban classification is considered Rural.
