This report from the European Project TABULA gives an overview of existing typology concepts in 24 European countries. Different approaches for building classification according to size and age have been examined. In many cases typical buildings are used as showcase examples to demonstrate the energy savings which can be achieved by implementation of refurbishment measures. In other cases typological criteria are used to assess a building's energy performance in a simplified way, for example in the framework of energy advice or energy certificate issuing. Sets of typical buildings in combination with statistical data are also used in order to model the energy performance of a total building stock on regional or national level. Based on the existing experiences conclusions are drawn with respect to the different application fields and target groups. A concept has been developed which allows the creation of regional / national building typologies in a harmonised way: these models enable an application on national level by use of national definitions (energy certificate, statistics). A conversion procedure is defined in each case which is used to transfer the building typology into the common typology data structure.
The study examines the experiences with building typologies in the European countries. The objective is to learn how to structure the variety of energy-related features of existing buildings. As a result of the enquiry it can be stated that there are a lot of different activities which are based on typological criteria. Some of them are concentrating on providing information material and conducting energy advice. On the other hand, building types are used for a better understanding of the energy performance of building portfolios on different levels: from the strategic planning of housing companies up to the evaluation of national policies and measures in the building sector.
On the basis of these experiences a common approach for building typologies has been developed. The core elements of this harmonised approach are a classification systematic, a structure for building and supply system data and a coherent energy balance method. Furthermore a uniform classification of statistical data enables a concerted approach for designing national building stock models.
Finally, a concise itinerary is described which allows experts to develop step by step a national or regional building typology which are compatible with the common TABULA approach.
