Collective awareness platforms offer innovative ways to engage citizens in becoming aware of and contributing solutions to sustainability challenges, such as climate change, water scarcity, or extreme weather events. Although such platforms have been successful in engaging citizens to contribute and self-organize during or directly after emergency situations, it has proven rather hard to motivate citizens to participate in preparing their local communities to address sustainability challenges whose effects are likely to be felt in the future and which they have not experienced yet. In this paper, we discuss the development, implementation, and assessment of a gamification model for a collective awareness platform for water-related sustainability challenges. The model is designed to address the motivational drivers of different user types and uses visualization elements to support gamified interaction in a way that relates otherwise intangible, abstract issues to more immediate (short-term), tangible objectives. The model was empirically validated with 507 users through a series of online experiments. The results confirmed a positive motivational effect in a large majority of participants and the suitability of the model to address different user types and various water-related sustainability issues. The findings will inform the design of gamification models for collective awareness platforms in sustainability-related domains.

Stimulating households to save energy with behaviour change support systems is a challenge and an opportunity to support efforts towards more sustainable energy consumption. The approaches developed so far, often either; do not consider the underlying behaviour change process in a systematic way, or do not provide a systematic linking of design elements to findings from behaviour change literature and the design of persuasive systems. This paper discusses the design and evaluation of a holistic socio-technical behaviour change system for energy saving that combines insights from behavioural theories and the persuasive system design in a systematic way. The findings from these two streams of research are combined into an integrated socio-technical model for informing the design of a behaviour change system for energy saving, which is then implemented in a concrete system design. The developed system combines smart meter data with interactive visualisations of energy consumption and energy saving impact, gamified incentive mechanisms, energy saving recommendations and attention triggers. The system design distinguishes between a version with non-personalized energy saving tips and a version with personalized recommendations that are deployed and evaluated separately. In this paper, we present the design and evaluation results of the non-personalized system in a real-world pilot. Obtained results indicate reduced energy consumption compared to a control group and a positive change in energy knowledge in the treatment group using the system, as well as positive user feedback about the suitability of the designed system to encourage energy saving.

Under H2020 program, the European Commission (EC) is investing in projects that aim to develop IT tools that are attractive for its users and therefore leading to a long-term behavior change for energy savings. Four of such funded projects are: BENEFFICE, enCOMPASS, MOBISTYLE and UtilitEE. To ensure exploitation and further uptake of the project results, EC provides Support Services for Exploitation of Research Results (SSERR). Through this support, a workshop was held at the Sustainable Places Conference 2019 to present the business value proposition of the above mentioned H2020 projects. This paper presents the outcomes of the workshop on how to pitch the research projects. Conclusive remarks were given to provide projects partners further recommendations on how to exploit the results to key actors (such as investors and business partners).
