abstract = {This paper reports on the different engineering, social and financial challenges behind the building and deploying electric energy monitoring and eco-feedback technology in real-world scenarios, which despite being relevant to the research community are seldom reported in the literature. The objectives of this paper are two-fold: First, discuss the technical and social constraints of real-world deployments. This includes, for example, hardware and software requirements, and issues related to security and intrusiveness of the monitoring solutions. Second, identify and understand the costs associated with developing and deploying such systems. These include hardware costs and consumed energy. To this end, we rely on over five years of experience developing and improving a non-intrusive energy monitoring research platform to enable the deployment of long and short-term studies of eco-feedback technology. During this time, two versions of that platform were deployed in 50 homes for periods that lasted between 6 and 18 consecutive months. By iteratively developing and deploying our sensing and eco-feedback infrastructures, we managed to build upon previous findings and lessons learned to understand how to create, deploy, and maintain such systems. Concurrently, we gained insights regarding what are some of the most relevant costs associated with running such experiments.},

abstract = {<p>This paper describes a tangible visualization that explores the link between the impact of energy feedback on household consumers and the resource demand impact on energy production. Specifically, it positions a novel perspective attempting to move beyond the known limitations of current eco-feedback systems and contributes to enhance our understanding of how consumers comprehend energy production. The work is informed by a comprehensive study of an installation that displays the ratio of current power generation sources and the percentage of grid renewables. The paper provides design insights for creating novel eco-feedback visualizations that leverage the balance between user lifestyles and the desire to influence consumption behaviors and practices. Evaluation results show an increase in energy literacy and awareness as well as identifies high consumer preferences towards simple, representative interfaces and ubiquitous immediate feedback. Our study shows potential in terms of future scenarios for eco-feedback in distributed energy micro-generation and other inevitable disruptive changes for the energy utility.</p>},

abstract = {<p>In this paper we present the challenges exposed during the designing, implementing and assessment of a novel eco-feedback system resulting from the intersection of human-computer interaction (HCI), and Digital Art. We explore how a digital art mode of inquiry can contribute to expose existing challenges in eco-feedback technology. Our new art inspired eco-feedback visualization, maps electricity consumption to effects on natural elements of the local natural landscape. The feedback was piloted with eight local families for four weeks. Reactions of the users were assessed through interviews and quantitative measures. Our findings showed that users found the mapping of the eco-feedback to artistic representations of elements of the natural environment somehow compelling, despite lacking of clear quantitative information. In conclusion, the conducted study provide useful findings and insights into future deployment of eco-feedback using artistic visualizations, information visualization and motivating behavior change</p>},
