AFTER project ends

On May 2014, the AFTER project has officially ended.

Please find included a direct access to the Publishable Report of the AFTER project.

This Publishable Report offers a complete overview on the project including a description of its scientific methodology, feedback on the energy savingĀ  measures tested on Pilot Sites and a general presentations of the main results and outputs concerning our Pilot Sites.

Comment on performance

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.

All the Factsheets include:

  • A general presentation of the measure from a technical point of view but also present some features regarding its maintenance aspects, and the tenants’ awareness that may be linked to the measure.
  • “tips” presented as a checklist to guarantee the good implementation of the measure.
  • A data collection proposing feedback regarding measures already implemented by the Social Housing Organizations of the AFTER project (costs for investments, number of dwellings concerned, normalized energy savings).

The Factsheets have been gathered in a catalogue in order to improve their readability and to provide a more consolidated package of innovations. You can find this report on the website: Overview of 84 best practices concerning the management and maintenance of the European housing stock

The Overview of 84 best practices concerning the management and maintenance of the European housing stock provides both quantitative and qualitative information about the main energy saving measures concerning the maintenance and the management of the social housing stock.

A particular effort has been carried out regarding the qualitative and pedagogical content for this report. When the quantitative information was missing, scientific partners have provided percentage extracted from the existing scientific literature. This overview is promoting the energy saving measures both from a practitioners’ point of view and also for a larger public concerned by energy savings.

The overview covers the following topics:

  • Operating management
  • Running maintenance
  • Replacement of the heating, domestic hot water and ventilation systems
  • Recently refurbished buildings
  • Recent low-energy buildings.

The experiences reported –of course- presents best practices with a high qualitative feedback.

The general range for performance is the following one:

  • Operating management: from 5% to 20% of savings regarding the former performance of the building.
  • Running maintenance: from 3% to 7,5% of savings regarding the former performance of the building.
  • Replacement of systems: from 10% to 45% of savings regarding the former performance of the building.
  • Refurbishments: from 25 to 80% of savings regarding the former performance of the building (depending on the types of refurbishment implemented).
  • Recent low-energy buildings: up to 75% of savings regarding the national standards concerning the performance expected for buildings.

The investments listed in the report present a large panorama of investments from less than 500 EUR/dwelling (maintenance and operating measures) to several millions of EUR for large refurbishment or very efficient new constructions.


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 buildings 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. These optimization solutions have been identified thanks to a direct collaboration between the Scientific partners of the project and the participating Social Housing Organizations.

These optimization solutions have led to additional energy savings from 1,6% to 21% after the implementation of the original energy saving measures.

The reports concerning our testing phase on Pilot Sites can be found on the Publications part of the website. There is one Saving energy through maintenance and management in… per country

Every Pilot Sites has shown the feasibility of the measures and their efficiency. In order to improve this transferability, general models for integrating the standard energy saving measures in the Social Housing Organizations’ routines have been created by the AFTER participants in the report: from the AFTER Pilot Sites to running routines for the European SHOs

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.

These results correspond to low-energy measures aiming at improving the results for already existing energy saving measures.

As a matter of fact if we report the total amount of energy saved thanks to the optimizations to a general performance we obtain a total amount of 5691,71. Toe/year. This amount is corresponding to higher investment that the AFTER measures will optimize (such as refurbishment, new low energy constructions, etc.).

Partners have particularly focused on the transferability conditions for every single measure in order to provide a more pragmatic state-of-the-art on how to implement a measure.


Tips and risks include aspects linked with tenants.

The CLCV – partner representative of the tenants has been involved in the general proofreading of the document.

Tenants have been informed on every Pilot Site (more than `1500 of tenants implied!) about the implementation of the optimized ESM.

Due to the technical aspects of some ESMs the tenants have not been involved in every process. Questionnaires have nevertheless been sent regarding the general satisfaction and behavioural aspects of the living in the Pilot Sites.

The measures directly impacting the tenants’ behaviours have been completed with an awareness process.

The part of the tenants’ behaviours in the general energy savings for an energy saving measure is very hard to assess precisely.

It is difficult to quantify the part of the kWh saved directly depending through tenants’ behaviours.

One general lesson may be that 1/3 of the tenants are pro-active stakeholders, 1/3 can be motivated with a particular effort concerning awareness and 1/3 is not interested in energy saving behaviours.  


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 ncluded in larger strategies aimed at reaching the 20-20-20 Energy strategies.

In order to achieve this goal, the planned forthcoming interventions of the participating SHO are detailed are detailed with their cost is and energy reductions objectives.

All the outputs concerning this part of the project are included in the report: Implementing strategies in the AFTER Social Housing Companies to reach Energy-2020 objectives.

The asset management plans show different strategies between the partners.

The economic context and the institutional position of the SHO is determining its possibility to anticipate its investment. Nevertheless, this deliverable provide interesting outputs regarding the efforts implemented in order to join the objectives of the Europe 20-20-20 strategy.


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

A Dissemination report presenting and detailing all these activities in available on the Publications part of the website.

The dissemination strategy of the AFTER project is success.

The project has been presented in some important national events in every country such as Home Fairs, National Congress for the Housing Sector, regional Congress on Energy Savings, etc.

Some partnerships have been implemented with other European projects tackling the same type of topics (ELIH-Med, BECA, ERHIN, SHELTER, etc.).
