  • Supporting Sustainable Living in the Home January 8th, 2010 Johnny Rodgers Dr. Lyn Bartram Dr. Rob Woodbury Human Centered Systems for Sustainable Living
  • Introduction • Master of Science student at SFU’s School of Interactive Arts & Technology • My research aims to make the consumption of residential resources evident to individuals through information visualization in order to support informed decision-making. • Approaches • Information Visualization • Interaction Design • Distributed/Ubiquitous Computing • Informative Art Human Centered Systems for Sustainable Living
  • First Big Project • North House Net-zero solar-powered home that placed 4th overall in the Solar Decathlon 2009 in Washington D.C. • ALIS: Adaptive Living Interface System Integrated control and feedback system Human Centered Systems for Sustainable Living View slide
  • Publications • Bartram, L., and Velikov, K. North House: Developing Intelligent Building Technology and User Interfaces in Energy Independent Domestic Environments. In Proc. of PLEA2009 - 26th Conference on Passive and Low Energy Architecture, Quebec City, Canada, 22-24 June 2009. • Bartram, L., Rodgers, J., and Muise, K. Chasing the Negawatt: Visualization for Sustainable Living. IEEE Computer Graphics & Applications, Spring 2010. • Rodgers, J., Bartram, L., and Muise, K. ALIS: Designing an interactive ecosystem for sustainable living. Submitted to CHI 2010 Work-In-Progress. Other Papers • Rodgers, J. Motivating residential energy conservation: A literature review of psychological and technological factors and techniques. Supervised by Dr. Ellen Balka. • Rodgers, J. Information visualization for grid-tied net-zero energy status awareness. Supervised by Dr. Lyn Bartram. Human Centered Systems for Sustainable Living View slide

  • What does the research tell us? Human Centered Systems for Sustainable Living
  • Literature Review Human Centered Systems for Sustainable Living
  • Decision Science • cognitive biases hinder conservation efforts • difficult to make choices that require short and medium term sacrifices for long term benefits • difficulty reacting to risks that are distant in time and space • “single-action bias” leads to small actions that salve our guilt and limit broader behavioural change (“never underestimate the human capacity for rationalization”) • collective discussion leads to better choices for the environment • elevation of social good over individual benefit • ordering of choices matters: show benefits before costs • need to frame messages in order to resonate with particular audiences • Christian responsibility to “tend and till the garden” • framing carbon fees as “offsets” rather than “taxes” Human Centered Systems for Sustainable Living
  • Behavioural Psychology • antecedent measures (availability of and access to information) not enough by itself to encourage conservation • consequences (feedback, carrots + sticks) • feedback is a good starting point, but again not enough by itself • disincentives (price increases) work better than incentives (rewards for top savers) in long term • intrinsic incentives (pleasure of saving) work better than extrinsic incentives (prizes), as conservation efforts diminish once extrinsic incentives are removed • social influences (commitments, group efforts, models) • relationship to decision science and social norms • combinations of interventions are critical to success in conservation efforts • feedback + public commitment • rewards + group challenges Human Centered Systems for Sustainable Living
  • Research Findings • Combine different motivational techniques in order to amplify the effects of each (such as informational feedback, rewards, and social influences) • Address multiple perspectives on energy conservation by catering to various motivations and mental models • Provide multiple methods of access to the same information • Support in-the-moment, situated decision-making as well as long-term planning (support both tactics and strategy) • Define baselines of energy consumption appropriate to individual circumstances • Account for the time scale during which a given intervention will need to remain relevant Human Centered Systems for Sustainable Living
  • Key Principles • Need to move from a model of expert management to one of aware occupancy • Integrating control and feedback technology into the home requires new techniques and a sensitivity to the unique constraints and affordances of a residential setting • we can’t just import existing techniques wholesale • we can’t “design for cardboard cutouts” • Displays on the wall are going to help residents answer some questions, but not all of them Human Centered Systems for Sustainable Living
  • Key Insights • Interventions need to span several dimensions of time, space, context, attention, and specificity (more on this later) • Emphasizing community interaction through social networking encourages energy conservation • challenges, tips, carpooling information, comparative data • “Ambient” information can help to create awareness and inform in-the-moment decisions • in contrast to the information made available by explicit, task-based tools Human Centered Systems for Sustainable Living
  • Need for a cohesive approach • Hesitancy of residents to adopt more work, more information • More information alone does not solve the problem • we can’t expect people to check their laptop every time they have a question • An interactive ecosystem of elements appears to be a promising approach to increasing awareness in the home • Numerous issues to be resolved concerning aesthetics, ergonomics, visibility, appropriate attentional requirements • Important to clarify control and energy systems that may be unfamiliar to homeowners through thoughtful design Human Centered Systems for Sustainable Living
  • Ongoing Research • Map the dimensions of resource consumption feedback techniques • Apply the motivational factors for resource conservation to the design of feedback systems • Determine guidelines for establishing meaningful resource use baselines for different individuals and different contexts • Explore the appropriate uses of read-only and interactive feedback mechanisms • Explore the design and implementation of information/visualization ecosystems to support sustainable decision-making • How do we know this works? The challenges of field-testing Human Centered Systems for Sustainable Living
  • Current Project • West House Living Lab An energy efficient small footprint laneway home incorporating solar energy production and interactive control and feedback systems (ALIS v2). Currently under construction and active development. • Ambient Canvas (version 2) An informative art display for incorporation into West House to provide light-based feedback on various measures of sustainability. Currently in the design and prototyping phase. Human Centered Systems for Sustainable Living
