Typology Approach for Building Stock Energy Assessment
During the IEE project TABULA, residential building typologies have been developed for 15 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.
Results in a nutshell
- Building type matrices (D4) for 15 countries, including all partner countries plus two associated partners.
- A webtool for disseminating the building typology concept, including typology information. The MS Excel workbook TABULA.xls is also available for flexible calculation of exemplary and average buildings with different supply systems.
- Evaluations of EPC databases with respect to typological criteria (D7) in 8 countries.
- Elaborated models for the national building stocks (D8) of 7 countries.
- Dissemination to experts, researchers and the EPBD Concerted Action.
- Despite the differences of building traditions and calculation standards in the participating countries TABULA demonstrated how it is possible to exchange and compare information about residential buildings’ shapes, construction elements, supply systems and energy performance in different countries.
- An important precondition was the definition of a "common typology language". A precondition for the acceptance and for the utilisation of the typology concept in the participating countries is the existence of a national approach which is consistent with national traditions and standards.
- This project was able to support decision making processes on the implementation of refurbishment strategies and the implementation of the EPBD at national and regional levels.
In April 2013, the European project EPISCOPE was launchedas a follow-up of the TABULA project. The typology concepts and contents developed during TABULA form an integral part of the new project and are therefore presented at this joint website together with the new EPISCOPE focus of building stock monitoring.
Project duration: 2009 - 2012
