Eco n' Home or how to reduce energy consumption in Household (ECO N' HOME)

Download PDFDownload PDF
Eco n’ Home aimed at exploring an innovative approach to reducing the energy consumption of households, by setting up a practical service for households that provides advice and identifies possible improvements in their day-to-day energy consumption. It consists of a home energy diagnosis that enables the advisor to report energy consumption and draw up a list of recommendations of behaviour changes and technical improvement solutions in the main fields of heating, electricity and transport. The experimentation of the service has taken 18 months. The main objective of the project was thus to create an available and reproducible tool for reducing domestic energy consumption, which could be used all over Europe and is based on a common methodology easily transferable to all parties interested in using this tool. In the long term the service could be also of use in the implementation of “white certificates”. The ultimate objective of Eco n’ Home is to achieve changes in behaviour that are sustained beyond the lifetime of the project and in the long-term.


  • Target reduction of CO2 emissions (1 ton per household per year) and energy consumption (10 to 20%) per household followed through behavioural changes, replacement and/or reconditioning of energy systems, appliances, regulation systems, and building envelope.
  • Communication activities to the public on the results of the project through the Eco n’Home website ( that has a section to count CO2 saved and kWh savings.
  • Dissemination of the project through informative papers (flyer, project guide), organisation of events to communicate on the project implementation with energy agencies, public and private organizations, public authorities (European conferences, workshops, meetings).
  • Setting-up of a methodology and common tools : Online database for the follow up of the participants and result of the project (kWh savings and CO2 saved), reports on diagnosis and energy-saving action plan, evaluation report of the action made.
  • Eco n'Home service as a possible tool for the implementation of “white certificates” and for the European Commission to apply to directive on “Energy efficiency and energy services”.

Lessons learned

  • Handling such an experimental initiative based on common practice of the 10 partners taking part in the project, is not a simple and straight-forward exercise. It is almost impossible to define one common methodology in detail, which each partner would have to apply. Rather, the point of developing a service like Eco n’Home is to build on existing experiences and tools of the different partners, but finding a consensus on common output.
  • We discovered as a consortium that there are limitations to how much data you can collect in one visit, and so, therefore, a trade-off has to be made between time and the amount and quality of data collected. Account should also be made of the assumptions made by some tools and software, for example regarding lifestyle patterns and behaviour.
  • The Eco n’Home initiative could be replicated by local authorities and energy agencies, and should be recognised at national and European levels as being an interesting tool for complying with the energy and climate policies. The Eco n’Home project guide, website and on-line tools should be used by organisations wishing to replicate the initiative, and organisations can contact the project partners for advice.
