Design to Reduce Energy Use In the Home

  1. 1. DESIGNTOREDUCEENERGYUSEINTHEHOMEImproving the Consumer-Facing Strategyand Innovating the System User InterfaceDesignManagement + InteractionDesign
  3. 3. Current statelimitations of PowcoCustomer-facingStrategyDesignManagement
  4. 4. PROBLEMS Dependence on consumer to moder- ate home energy usage.OUT THERE Existing incentives are not enough to catalyze change. General lack of consumer awareness of energy supply limits and POWCO strategic goals.DesignManagement
  5. 5. COMMUNICATION POWCO wants to communicate a complex message. “We want you to use less, but we are capable of providing.” Ambiguous, ineffective service brand messaging. Large, unmet challenges in shaping communication. Obtusely communicated incentives and promotions. No active feedback loops (conversations). Lack of tailored/targetted consumer messaging.DesignManagement
  6. 6. TECHNICAL Power companies require the customer to do the vast majority of the legwork Site energy calculators are hard to use, ineffective Until recently with the implementation of smart meters, there was no feedback as to the user’s energy consumption until the monthly bill arrived.DesignManagement
  7. 7. RAISE AWARENESS How do customer feel about interacting with the power company? Do they think it works? Why? Do they think it is broken? How? What is their experience from the first phone call to paying the final bill?What would get them excited?
  8. 8. Ideas fora proposedsolutionDesignManagement
  9. 9. RAISEAWARENESSSolutions It isn’t just the service, it is how that service makes the customer feel. Free home energy diagnostic with account setup for residences. Use real numbers to shock them or make them feel their choices really do matter Send energy saving tips via the web, email, or textDesignManagement
  10. 10. INCENTIVES Credit Union or COOP approach Rebates, Point/Reward Systems Community-Based. Challenges/Competitions/Partnerships Tailored Incentives for Generational/Demographic Groups. Upgrading Older Homes/AppliancesDesignManagement

  12. 12. CONVENIENCE Associate new behavior with an existing routine Less work for customer Easy to understand Convenient features such as auto bill pay, local weather,efficiency modeDesignManagement
  13. 13. USER CENTEREDIntroduce ownership User is in control of total home energy profile. User can create settings and goals around personal preferences. Mobile app options for greater flexibility, controlDesignManagement
  14. 14. FEEDBACK Give user frequent feedback about the consequences of their actions. Detailed energy usage Real-time savings/loss Understand consequences and make better choices Introduce or increase present gains Choice bracketing - daily vs yearly totals Tips for saving energyDesignManagement
  15. 15. Powco reaching out to customers Educational institutions are important partners. Develop better customer relationships TEAMWORKDesignManagement
  16. 16. MARKETINGMESSAGE Communicate specific goals Social networking Possible message “Save Energy: For your home and yourself”DesignManagement
  17. 17. BENEFITSFor the power company Improved customer and community relationships Decreased strain on existing facilities Poised to usher in new, sustainable technologiesDesignManagement
  18. 18. BENEFITSFor the consumer Ownership of home energy usage Greater savings Sense of responsibility—home own- ership, energy usage, conserving re- sourcesDesignManagement
  19. 19. BENEFITSFor the environment Less energy waste Reduce carbon footprint Explore renewable energy sourcesDesignManagement

  46. 46. SCENARIOSGEN-Y: AMY&JAKEJake and Amy are college students living inan old drafty house.Amy comes home from her eveningwaitressing job, sits down at the kitchentable and counts her tips. After shediscovers that she barely has enoughmoney to buy groceries for herself for theweek, she tries to take her mind off ofthings by opening the mail.”The electric bill is $149! What are thoseboys doing in this house? What can I do?"

  56. 56. “I have a couple of Energy Star rated appliances,but I don’t really know why they are good. I like theidea of being efficient, but honestly, I just wantedthe rebates.”
  57. 57. “We love Christmas lights, andI think they don’t use a lot ofelectricity, so we leave them onall day.”“We set the goal to change thetemperature on the thermostat byNovember 1st and the same forJune 1st, but sometimes it is sodifficult...”“Yeah, we use those lightbulbs but you know I don’t likethe color..” They agree on almost everthing related to the energy. They use a programmable thermostat that is on from 6:00 and 8:00p.m. Summer is 68 and in winter it is 75. InteractionDesign
  58. 58. HOME People make an effort to look good in front of others.INTERVIEWS: Most wanted to conserve energy but didn’tWHATWE know that much about what to do.LEARNED Homeowners often think of efficiency in terms of big projects, rather than daily practices. Thermostat control can be an area of frustration among members of a household. People do not have a very clear understanding of how their energy bill is calculated. Most people are more interested in saving money, than they are in being green.
