Interactive Demand Shifting: in the Context of Emerging Energy Technologies

We are entering a key time period for home energy. While ubiquitous computing takes an increasing space in our daily life, emerging energy technologies including local generation and electric vehicle are leaving the stage of pioneer's users to become more common. This research highlights the potential of new energy behavior supported by digital tools in the context of domestic solar electricity generation

Interactive Demand Shifting in the context of Domestic Micro-Generation

The combination of ubiquitous computing and emerging energy technologies is radically changing the home energy landscape. Domestic micro-generation, dominated by solar photovoltaic, is increasing at a rapid pace. This represents an opportunity for creating and altering energy behaviours. However, these transformations generate new challenges that we call the domestic energy gap: domestic electricity consumption and microgeneration are out of sync. Micro-generation is mainly uncontrollable production relying on weather while domestic energy consumption tends to happen mostly during the evening. This thesis focuses on understanding and supporting new domestic practices in the context of domestic solar electricity generation, looking at ‘Demand-Shifting’. Specifically, we look at how can digital tools leverage Demand-Shifting practices in the context of domestic micro-generation? Relying on a mixed-method approach, we provide a qualitative and quantitative answer with the collaboration of 38 participating households in several field studies including two spanning more than eight months. Through a deep investigation of laundry and electric mobility routines in the context of domestic micro-generation, we emphasised a natural engagement into Demand-Shifting which appeared as a complex and time-consuming task for participants which was not visible when we analysed their quantitative data. We revealed this complexity through Participatory Data Analyses, a method we designed to analyse the data in collaboration with the participating householders. This provided us with a comprehensive view of the relationship between domestic micro-generation and daily routines. Finally, we highlight the need for timely and contextual support through the deployment of interventions in-the-wild. Building on discussions of our findings in perspective of the literature, we propose a conceptual framework to support domestic interactive Demand-Shifting

Participatory Data Analysis: A New Method for Investigating Human Energy Practices

This paper presents a novel data-driven method to investigate the interdependence between technology design and human energy practices. The method – called Participatory Data – makes use of fine-grained energy data collected via smart meters and smart plugs, and behaviour visualisation during home visits to spark self-reflection among householders

Energy Demand Shifting in Residential Households: The Interdependence between Social Practices and Technology Design

Emerging energy technologies, such as smart meters and solar photovoltaic systems (solar PV), are changing our relationship to energy. There is increasing evidence that households with solar PV on their roof tend naturally to shift their energy consumption in time to match their local generation, but what do people actually do to achieve this and how ICT can support them to optimize their consumption? In this paper we present a year-long user study to understand social practices around laundry routines and local energy generation. We highlight four challenges for the next generation of home energy management systems

Understanding and Supporting Emerging Domestic Energy Practices

The current transformation of the domestic energy landscape, including local generation, new consumption and storage, requires rethinking our research approach. This paper reports experiences from two case studies with their implications for future HCI research in the home

Technology probes: experiences with home energy feedback

We discuss our experience in applying a Technology Probe approach to the study of new concepts and technologies at home. We discuss benefits and challenges of using this methodology based on an experiment which aimed to bring solar panel energy feedback into everyday life

Exploring the future of data-driven product design

Connected devices present new opportunities to advance design through data collection in the wild, similar to the way digital services evolve through analytics. However, it is still unclear how live data transmitted by connected devices informs the design of these products, going beyond performance optimisation to support creative practices. Design can be enriched by data captured by connected devices, from usage logs to environmental sensors, and data about the devices and people around them. Through a series of workshops, this paper contributes industry and academia perspectives on the future of data-driven product design. We highlight HCI challenges, issues and implications, including sensemaking and the generation of design insight. We further challenge current notions of data-driven design and envision ways in which future HCI research can develop ways to work with data in the design process in a connected, rich, human manner

FMR1 premutation and full mutation molecular mechanisms related to autism

Fragile X syndrome (FXS) is caused by an expanded CGG repeat (>200 repeats) in the 5′ un-translated portion of the fragile X mental retardation 1 gene (FMR1) leading to a deficiency or absence of the FMR1 protein (FMRP). FMRP is an RNA-binding protein that regulates the translation of a number of other genes that are important for synaptic development and plasticity. Furthermore, many of these genes, when mutated, have been linked to autism in the general population, which may explain the high comorbidity that exists between FXS and autism spectrum disorders (ASD). Additionally, premutation repeat expansions (55 to 200 CGG repeats) may also give rise to ASD through a different molecular mechanism that involves a direct toxic effect of FMR1 mRNA. It is believed that RNA toxicity underlies much of the premutation-related involvement, including developmental concerns like autism, as well as neurodegenerative issues with aging such as the fragile X-associated tremor ataxia syndrome (FXTAS). RNA toxicity can also lead to mitochondrial dysfunction, which is common in older premutation carriers both with and without FXTAS. Many of the problems with cellular dysregulation in both premutation and full mutation neurons also parallel the cellular abnormalities that have been documented in idiopathic autism. Research regarding dysregulation of neurotransmitter systems caused by the lack of FMRP in FXS, including metabotropic glutamate receptor 1/5 (mGluR1/5) pathway and GABA pathways, has led to new targeted treatments for FXS. Preliminary evidence suggests that these new targeted treatments will also be beneficial in non-fragile X forms of autism

Déplacement interactif de la consommation d'électricité dans le contexte de micro-génération domestique

La combinaison de l'internet des objets et des nouvelles technologies liées à l'énergie transforme le paysage de l'énergie dans la maison. Les installations de micro générateurs, dominées par les panneaux solaires photovoltaïques, sont en constante progression. C'est une opportunité pour la création et l'altération des comportements énergétiques. Cependant, ces transformations créent également un nouveau challenge que l'on appelle le « différentiel énergétique » à l'échelle de la maison : la consommation et la génération d'électricité des ménages sont désynchronisées. En effet, la génération locale est majoritairement incontrôlable et dépendante des conditions météorologiques alors que la consommation des ménages à tendance à se concentrer en soirée. Cette thèse vise à comprendre et supporter les pratiques de déplacement des consommations émergentes dans les ménages équipés de panneaux solaires photovoltaïques. En particulier, nous observons « Comment les outils numériques peuvent-ils tirer parti des pratiques de déplacement des consommations dans le contexte de micro génération domestique ? ». Pour adresser cette question nous avons combiné des approches empiriques et d'ingénierie, se renforçant et s'informant mutuellement les unes et les autres pour fournir une solution générale. Cela inclut la collection de données qualitatives et quantitatives, des analyses en collaboration avec les participants, des études longitudinales, des interviews, du co-design, des simulations et des tests en condition réelles. Tout au long de cette thèse, nous avons utilisé une méthodologie centrée sur l'utilisateur à chaque étape pour informer et valider la recherche en collaboration avec 38 ménages. A travers une investigation approfondi des routines telles que faire la lessive et se déplacer en voiture électrique, nous soulignons l'engagement naturel des ménages pour le déplacement des consommations. Cependant, cette activité se révèle complexe et fastidieuse. Nous révélons cette complexité à l'aide d'une analyse de donnée participative, une méthode élaborée afin d'analyser les données en collaboration avec les participants. Nous construisons une compréhension détaillée de la relation entre la génération d'électricité domestique et les routines du quotidien. Enfin, nous soulignons le besoin d'un support contextuel à travers le déploiement d'interventions sur le terrain. En perspective de la littérature, nous proposons un modèle conceptuel pour le support interactif de déplacement des consommations.The combination of ubiquitous computing and emerging energy technologies is radically changing the home energy landscape.
