Factor 4
The Factor 4’s main objective is to improve the energy efficiency of social
housing buildings by
30 % in a short term and more in a long term in order to participate to the
reduction of GEG emissions by a factor 4 until 2050 by:
- real retrofitting actions (including upon the use of the building) on buildings
which will still be there in 2030-50
- technical and non technical recommendations (after an analysis of non technical
barriers and a European synthesis), training and dissemination actions, for
encouraging other social owners, public and private owners, public administration
and local authorities to manage actions (financial ones, rules, regulation
(building permit, land planning documents), etc.)
The objective is to define strategic plans and accompanying measures aiming
at the reduction of GEG emissions by a factor 4 from 2050, by creating a permanent
action plan in order to achieve this objective. Factor 4 aims at being a real
actor in the European strategy as regarding GEG.
