Key Figures

2011: Start of the project

  • 2,7M budget granted for 75 % by the European Commission.

  • 18 partners and 6 Social national housing organisations managing 103 000 housing units.
  • 200 professionals participating in 3 National workshops and final seminars (Social Housing Organizations, National Housing Associations, Scientific and Research Institutions, Tenants’ Representatives Associations).
  • 3 pre-tested standard energy saving measures per country targeting an immediate energy reduction of 3 to 7,5%.
  • 3 pilot sites per country demonstrated the feasibility and efficiency of well-developed energy saving measures.
  • Promoting low-cost innovations: under 500€/housing unit.


2014: Results and conclusions















  • 84 Factsheets concerning the main energy saving measures implemented in the European Social Housing Stock from 2006 to 2011 concerning the running maintenance and the operating management.
  • 3 tested standard Energy Saving Measures have been implemented in the 6 participating country for a total of 824 dwellings. These measures have impacted the existing energy performance of the buildingswith saving from 5% for low-cost investment concerning maintenance (hydraulic balancing of the systems for example) up to 40% (global refurbishment of the building). Corresponding optimization solutions directly financed by the AFTER budget have completed these measures.
  • The general level of performance is highly satisfying with more than 1811 MWh (398,42 toe/year) saved on the AFTER Pilot Sites. The corresponding amount of energy represents the savings obtained thanks to the optimization solutions of existing energy saving measures. These optimization solutions correspond to approx. 3 to 7% of complementary savings after the implementation of the original Energy Saving Measure.
  • Tenants have been informed on every Pilot Site (more than `1500 of tenants implied!) about the implementation of the optimized ESM.
  • Participating SHOs have included the quantitative objectives of energy reduction in their asset management plans. The outputs of the AFTER optimized measures tested during our monitoring period have been included in larger strategies aimed at reaching the 20-20-20 Energy strategies.
  • More than 200 professionals have participated in the general dissemination activities of the AFTER project. Specials workshops have been organized in the participating countries gathering professionals of the housing sector but also research institutes, tenants representatives, architects, politicians, etc. Around 20 articles have been published concerning the project and its main results in scientific or professional reviews
