Objectives

The TABULA WebTool has been developed within the framework of the Intelligent Energy Europe projects TABULA and EPISCOPE.
The objective is to disseminate the general idea of national residential building typologies to building experts from European countries and to give them an understanding of the concrete implementation according to the TABULA concept www.episcope.eu/building-typology:

  • The division of residential building stocks in size and age classes;
  • Data of exemplary buildings: visual appearance, commonly found construction elements and corresponding U-values;
  • Data of exemplary heat supply systems: commonly found system types and their energy performance indicators;
  • Typical values for the energy consumption by energy carriers;
  • For old buildings: energy saving measures on two quality levels and their impact on the energy consumption;
  • For new buildings: examples for realisation on three energy performance levels: minimum requirements, improved and ambitious or NZEB standard (assumed or announced level of Nearly Zero-Energy Buildings).
  • Standard reference calculation procedure based on an agreed data format, user conditions and national climatic data;
  • Calibration of the standard calculation procedure to the typical level of measured consumption.

Section "Building Typologies" – Principles and Functions in a Nutshell

  • According to the TABULA concept a national residential building stock is divided in size and age classes. The resulting grid is called "building type matrix". Each element of this main matrix is a "generic building type" (indicated by the building type code suffix "Gen"). In principle, each residential building of a national stock can be assigned to one generic building type of the national building type matrix. Information about frequencies of buildings per building type can be found at the "Country Pages" of the EPISCOPE website.
  • Further divisions in sub-types have been created in some countries to consider special building appearances or construction principles (indicated by the code suffix being different from "Gen").
  • The TABULA WebTool assigns to each of the building types one exemplary building. Similar buildings (with regard to appearance and structure) can commonly be found in the countries. The exemplary building represents one possible occurrence within a wide range of each property and cannot be seen as representative in a statistical sense.
  • In some cases datasets of exemplary building have not yet been assigned to building types (even though pictures are already existing). The building pictures are displayed only in a wash-out manner and there is no energy performance calculation.
  • The energy performance is calculated by use of the TABULA reference calculation procedure (www.episcope.eu/fileadmin/tabula/public/docs/report/TABULA_CommonCalculationMethod.pdf). In the standard mode the charts of the webtool are displaying the calculation results calibrated to the typical level of measured consumption. By changing the settings of the tool it is possible to switch to the standard calculation (not adapted). If for a country calibration factors are not available (even not on an expert estimation basis) adaptation factors averaged for the other countries are used.
  • In the programme settings also the energy carrier assessment (non-renewable and total primary energy factors, carbon dioxide emission factors, energy prices) can be switched from European standard values to national values. The national values have been provided by the responsible partners. The European primary energy factors are based on prEN 15603:2013, Table A.8; the CO2 emission factors have been derived from EN 15603:2006, Annex E."
