Workshop Guide 09:00 Welcome 09:10 Block I: The European Housing Stock – Overview and Typological Assessment 09:10 Oliver Rapf – Buildings Performance Institute Europe (BPIE) – Belgium
”European Buildings under the Microscope“ Buildings present one of the highest energy saving potentials. Improving energy efficiency of buildings can substantially contribute to Europe’s 2020 strategy and 2050 roadmap targets. The transformation of the existing building stock is a complex process requiring an understanding on the current status of the building stock. Based on an extensive survey carried out across the EU, BPIE shows that significant efforts are required to close current data gaps and harmonize monitoring, reporting and evaluation. The data collected is used in a model which develops renovation scenarios assuming different renovation depth and speed pathways and achieve the same overall target: to renovate all the existing stock by 2050.
Oliver Rapf is the Executive Director of The Buildings Performance Institute Europe (BPIE). Before joining BPIE, Oliver Rapf was Head of the Climate Business Engagement unit of WWF International, managing strategy and partnership development with the private sector. Leading an international team, he advised multinational companies on climate change. Oliver’s experience in buildings efficiency goes back to the late 1990s when he was a project leader for several deep renovation projects on behalf of WWF in cooperation with housing companies across Germany. Other roles include the position of deputy Head of WWF’s European Climate Change and Energy Policy Unit. Oliver participated in UNFCCC negotiations and was the leader of the German NGO coalition at international climate change negotiations.
09:45 Tobias Loga – Institute for Housing and Environment (IWU) – Germany
”National building typologies: basis for energy consultancy and building stock models – the TABULA project“
A national building typology on the basis of the TABULA concept provides a basis for energy consultancy and for building stock models. It is created by classifying the building portfolio according to certain energy‐related parameters and assigning an example building to each building type. A further step is the creation of "average buildings" as representatives, on condition that the necessary statistical information is available. A common reference calculation procedure facilitates the cross‐border exchange of information about the energy performance of typical buildings and particular refurbishment strategies.
1989 to 1991 energy consultancy in an architectural office; since 1992 scientist at IWU – Institut Wohnen und Umwelt GmbH (Institute for Housing and Environment), Darmstadt, Germany. The fields of expertise of Tobias Loga are: design of energy efficient buildings, development of tools for calculating energy balances and for energy advice, concepts and implementation of energy performance certificates, simplifications for energy performance calculations, building typologies.

11:35 Marjana Sijanec Zavrl – Building and Civil Engineering Institute (ZRMK) – Slovenia Early attempts to assemble Slovenian building typology have been made in the past with only two size types (single family houses and apartment building) and without the contribution of building systems. TABULA approach brought a new concept to the building typology. By defining typology subtypes it was possible to describe buildings not only in their original state but also in present modernized state, thus enabling us to model national energy balance and saving scenarios. Based on this typology, a new TABULA‐based software for quick energy saving calculations for residential buildings was developed.

12:05 Nele Renders – Flemish Institute of Technological Research (VITO) – Belgium
”Realistic saving potentials? The correlation of calculated and actual measured energy use“
The correlation of calculated and actual measured energy use: evaluation of an energy advice and consequences for building stock assessment. The theoretical energy consumption tends to be much higher than the actual energy use due to occupant behaviour, especially for older buildings. In order to present realistic energy savings, we add a correction factor to the theoretical energy estimations. These correction factors are derived from statistical analysis of the Energy Advice Procedure databases of Belgian dwellings. We applied the factors in our two approaches to model the energy use of dwellings, namely in the typical and the representative housing approach.
Nele Renders graduated in 2005 as Bio‐Engineer in the Environmental Technologies at the Katholieke Universiteit Leuven. That year, she started working at VITO or the Flemish Institute of Technological Research. She is involved in the estimation of the energy and emission projections for different regional levels: federal, regional or city level. In this context, she is responsible for the residential and service sector. Within this scope, she developed the Flemish Environmental Costing Model for the building sector. Moreover, in the European study “Assessment and improvement of methodologies used for greenhouse gas projections“ she set up tiered guidelines for the building sector. In addition to modeling, she evaluated the REU‐reports (Rational Energy Use) of the Flemish administrators of the distribution network.

13:50 Maria Amtmann – Austrian Energy Agency (AEA) – Austria ”Definition of average buildings – Statistical information from the Austrian EPC database ‐ Use for the building stock model Austria“
The development of a building typology could be accomplished by combination of available data information out of an EPC database, literature sources and national statistics. Average values taken out of literature were used to select one typical building for each typology out of the EPC database. As "representative" apply buildings which in terms of their U‐value, gross floor area, space heating and domestic hot water systems represent average buildings. Thus, the 28 national model buildings for the national brochure and the 140 model buildings for the webtool are finally represented by real, existing “average” buildings.

”Characterisation of dwellings in the UK – determining the potential for enhanced energy efficiency“
The housing stock in England is among the oldest in Europe. Much of this is in poor condition with low levels of energy efficiency. Characterisation of the English housing stock must consider the dwelling condition, size, built form and presence of existing measures to allow the assessment of the potential for improving energy efficiency. The comprehensive data from the English Housing Survey allows the development of relevant typologies and quantify the likely effects of energy efficiency improvements.
John joined BRE in 1998 to lead the energy efficiency modelling work for housing. He now manages the Housing Stock Performance Group where he is responsible for energy modelling, energy statistics, housing stock modelling and social research.
