Based on the common DATAMINE data structure and the experiences of typological classification the TABULA project was launched in 2009. The idea was to make an agreed systematic approach to classify building stocks according to their energy related properties.
During the IEE project TABULA residential building typologies have been developed for 13 European countries. Each national typology consists of a classification scheme grouping buildings according to their size, age and further parameters and a set of exemplary buildings representing the building types. They have been published by the project partners in national “Building Typology Brochures”, written in their respective languages. As a common element all brochures contain double page “Building Display Sheets” for all example buildings on which energy related features and the effects of refurbishment measures are illustrated graphically.
To exchange information on the European level the “TABULA WebTool” provides an online calculation of the exemplary buildings from all countries, displaying their energy related features and the possible energy savings by implementing refurbishment measures. Basis of the TABULA WebTool is a simple and transparent reference procedure for calculating the energy need, the energy use by energyware and the energyware assessment (primary energy, carbon dioxide, costs).
Apart from the reference calculation used for cross-country comparison a calibration of the calculated energy use to the typical levels of actual consumption is foreseen – with the intention to enable a realistic assessment of energyware and heating costs savings. Based on the residential building typologies building stock models have been created for seven countries which enable a projection of the actual national building stock consumption and the energy saving potentials.
