for setting out sustainable energy retrofitting policies
Factor 4 Programme of actions towards a factor 4 in existing social housings in Europe
Description and objectives
The Factor 4 project is focussing on social housing retrofitting for improving the energy efficiency and the use of renewable energy in order to participate to the reduction of greenhouse gas emmissions by a factor 4 before 2050. Its objective is to help socal owners to optimise their retrofitting programmes for their whole building stock and to set up strategies towards energy efficiency and the factor 4. The Factor 4 approach is based on the Lyfe Cycle Energy Cost (LCEC) analysis
Factor 4, Programme of actions towards Factor 4 in existing social housings in Europe
Factor 4 is a SAVE project partly funded by the EUROPEAN COMMISSION – Intelligent Energy – Executive Agency for Competitiveness and Innovation (EACI) - (Grant agreement EIE/05/076/S12.419636)
The Factor 4 project
The Factor 4 project follows the Sustainable Development World Strategy, the Kyoto protocol and the European energy policy which is to reduce by a factor 4 energy consumption in European countries before 2050.
It is focussed on social housing retrofitting for improving energy efficiency and facilitating the use of renewable energy, in order to participate to the reduction of greenhouse gas emission (GEG) by a factor 4 before 2050.
The Factor 4 project aims at:
The Factor 4 project’s objective is to help social owners to set up sustainable energy retrofitting strategies for their whole building stock taking into account energy savings and the reduction of greenhouse effect gas (GEG) emissions towards a factor 4 according to the European policy which is to cut by 4 GEG emissions before 2050.
The life cycle energy cost analysis allows to set out these sustainable strategies because it allows to deal together with energy savings, the reduction of GEG emissions and socio economic issues such as the pay back return for social owners and the reduction of charges for tenants.
The Factor 4 approach for setting sustainable strategies for energy retrofitting of social housing building stocks and at territorial scales
The Factor 4 approach allows to reach the factor 4 levell (note 1)and to identify the necessary technical and economic means.
The Factor 4 approach is for various actors:
The Factor 4 approach is focussed on a life cycle energy cost (LCEC) analysis and made of the 3 following phases:
List of deliverables and newsletters to download
There are deliverables for each step of the Factor 4 approachThe first step on the housing sector and on the building typology
The second step with the building analysis:
Sustainable Energy Europe, a European campaign to raise awareness and change the landscape of energy" et " Energie durable pour l'Europe, campagne européenne de sensibilisation pour changer le paysage climatique
The Final conference was the 2nd of June 2008 in Paris at MEEDDAT, the French ministry of Ecology, Energy, Sustainable Development and Land Planning. It was supported by PUCA, a public administration in charge of research in Urban, Construction and Architecture.
180 participants were registered and more than 150 participated:
A book gathering the slides has been distributed to the participants and can be download. It contents:
- the front and last pages (cover),
- 1. the main issues of housing energy retrofitting in Europe
- 2. Life Cycle Cost analysis
- 3. The ASCOT model
- 4. The VROM model
- 5. The BREA model
- 6. The SEC model
- 7. The life Cycle Cost analysis for a neighbourhood analysis and a building stock strategy (with the Factor 4 / SEC model), for new housing (without pictures) and the last presentations (on standards…)
The SEC model is regularly improved and is usable since 2009 for single houses and for private ones. The users (social owners, local authorities, local energy agencies, etc.) are gathered in users groups in order to share results and experience on the one hand and to allow a regular updating of the model (price evolution, new technologies, etc.). »
