What is the TABULA project all about?

The aim of the Intelligent Energy Europe TABULA project (2009-2012) is to create a building typology in each of the member states participating in the project. In the case of Ireland, the building typology aims to identify the most common residential building types and to provide relevant building energy information for each type that will be of use to home owners and building professionals alike.

Information on TABULA is being made available to energy consultants and the general public via two key channels, namely through (1) the TABULA building typology webtool and (2) brochures for each participating country giving an overview of the energy performance of typical buildings and the possible energy savings by refurbishment measures.

An overview of the all national building typologies in TABULA is initially provided by the “Building Type Matrix” that forms the presentation format of the TABULA webtool. In the Irish Matrix only the most relevant three size classes have been developed as indicated in the image below. The generic types (with the most common features) of single family houses, terraced/semi detached houses and apartment blocks are presented on the first page of the building type matrix as shown below.

The second page of the Matrix shows a more detailed breakdown of the construction types in the specific age bands. Special attention has been given to the houses built before 1978, where 7 different wall construction types have been distinguished. In the remaining age bands, one extra wall construction type has been added in addition to the generic wall type from the first page.

More information is available on the “country pages” section of the TABULA website:

TABULA Typology Brochures

Individual brochures have been prepared for the 30 Irish dwelling types (29 house types and one apartment type) within the Irish typology in the form of double sided A4 sheets showing BER analysis for each type using the Irish DEAP method. All 30 individual brochures have also been compiled into one National Irish Typology brochure. You can find the Irish brochure at that link

TABULA Webtool

While the brochures provide BER information based on the Irish national Building Energy Rating (BER) method known as DEAP, the TABULA webtool provides analysis of all dwellings within the typology based on a common EU methodology. Thus, all the building of all partner countries can be analysed and demonstrated using a common calculation engine.

The TABULA webtool is available at
