About the Project

Buildings account for around 40% of EU energy requirements.

In the last five years, Social Housing Organizations have played an exemplary role in improving
the energy efficiency of the housing sector
. They have anticipated forthcoming national legislation and have punctually experimented with the construction of low-energy buildings and innovative energy refurbishment.

The objective of the AFTER project was to promote and continue this effort especially in light of the obstacles and challenges presented by the current economic situation.


The AFTER project aimed to enable participating and non-participating Social Housing Institutions and Organizations all over Europe to improve the energy efficiency of their housing stock with cost optimal solutions. Its goal was to promote and develop existing European knowledge in the areas of energy saving strategies and encourage their implementation by companies in the housing sector.

AFTER asserted the importance of establishing energy efficiency as a major goal,  even after construction of the building. The project promoted measures adapted to a variety of investments and situations. A special emphasis was placed on the important contributions of operation maintenance and management in the energy performance of buildings.

“About the Project”: Facts and Figures


AFTER associated retrospective analysis, short-term proposals and long-term investment strategies.

The project implemented a step-by-step integrated process that can be broken down as follows :

  • Performance assessment of technical solutions experimented over the last five years(performance, cost-optimal effectiveness, tenants’ opinion, etc…).
  • Definition of new optimum economic, technical and social standards and measures focusing on the management and maintenance of buildings as well as the eco-empowerment of tenants.
  • Testing and final assessment of new energy saving measures on sites focusing on their future generalization.

Social Housing Organizations in 6 different countries (Czech Republic, Denmark, France, Germany, Italy, and Slovenia) and their partners -including National Housing Associations, Scientific Committee and National Tenants Associations-  cooperated to promote the most efficient and adaptable solutions.

This diversity of the different AFTER stakeholders created a better collaboration between all of the actors in the social housing sector with the shared goal of improving and consolidating their energy efficiency.
