| Summary/Abstract |
Nowadays, in Europe, the main challenge is not only the construction of new high performing buildings, but also the promotion of proper retrofit actions on existing buildings. In the on-going transition towards low carbon cities, tools to support local municipalities are fundamental.

| Summary/Abstract |
Retrofit actions applied to the existent building stock aim at increasing the energy performance, considering the optimal trade-off between energy savings and costs, according to the Directive 2010/31/EU. To select effective refurbishment measures and to quantify the energy saving potentials of the existent building stock, the analysis should be performed on "reference buildings".
This article presents a methodology for the identification of reference buildings, according to the IEE-TABULA project (2009-12) aimed at creating a harmonised structure for "European Building Typologies". Among the possible applications of the building typology, this work focuses on the potentialities of energy savings and CO2 emission reductions for the European residential building stock. In particular, the Italian approach to model the energy balance of a subset of the national building stock is described; the results show the enormous potentialities of energy savings even with basic energy retrofit actions. Cost analyses were not in the scope of the project, but the results of this study are the basis for further investigations aimed at assessing the cost effectiveness of sets of measures. In this regard, the TABULA building-types are being applied by the Italian government for calculating cost-optimal levels of energy performance, complying with the Directive 2010/31/EU objectives.
