The Encerticus project has finished with successful results and has achieved the main objectives set up at the beginning of the project. The focal point lies in the impact analysis of the ICT solutions that have been developed and operated by the participating pilot sites. These solutions were aimed at User Awareness Services (UAS) and Management Services (MS).
The Manresa pilot site (Spain) services, with 44 dwellings involved, provided a monthly energy report about the energy use to the household together with a mobile app, called “Controla Energia” providing online energy use feedback to the tenants. The global savings achieved are 7% in electricity, 2% in water and 1% in thermal energy.
The UAS and MS in the Prato pilot site (Italy) consists of a real time electricity display, web-based service, human coaching and monthly energy reports that were provided to 15 households. The achieved savings are 10% in electricity.
In Marseille, the French experience has had the most innovative contribution with the “Jeko” game. Based on the nudge theory, “Jeko” (in French “J’économise”) involved 15 households in the task of reducing the energy use. The energy savings in the pilot site are 10% in electricity and 2% in thermal energy.
The analysis also revealed that the achievement of savings also depends on the initial situation of the pilot sites. When tenants already consumed very little energy/resources during the baseline period, the potential for the achievement of savings is very low. This applies, for example, to the experimental group of Manresa where it was very difficult to achieve further savings. That is why it can be interpreted as being quite successful if the experimental groups actually had a better performance, even though they had a lower baseline consumption than the control group.
Furthermore, for social housing tenants it is especially difficult to achieve meaningful savings as their incomes are low and they have limited capital to replace old electrical appliances with energy efficient ones that would have a bigger impact on consumption.
