TABULA building typologies in 20 European countries—Making energy-related features of residential building stocks comparable

The concerted TABULA typology concept includes structural information and datasets of housing stocks from 20 European countries. It is being used for showcasing the effect of energy saving measures, for cross-country comparisons of building and supply system features as well as for setting-up housing stock models. [Display omitted] •A concerted concept of residential building typologies has been developed.•The concept has been implemented in 20 European countries.•A common calculation method is used including a calibration to typical consumption.•Cross-country comparisons were performed for 600 residential buildings.•Average buildings have been used as simplified building stock models. In the framework of the international projects TABULA and EPISCOPE residential building typologies have been created in 20 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 these building types. U-values of different age bands and energy expenditure factors of heat generators of these buildings are being compared. In addition, synthetical average buildings have been defined which are statistically representative for specific age and size bands and enable projections of the energy performance to the total housing stocks. Based on the common data structure the energy performance of the average buildings is calculated in a standardised way to form simplified housing stock models. In the context of inhomogeneous building stocks of European countries the results allow an understanding of the average and variation of parameters like U-values, supply system performances or final energy.
