Design Goals in a Nutshell (1) Provide energy data:•Near real time feedback (~10 seconds)•Floor-level granularity

(2) Improve student “energy literacy”• Increase knowledge, improve attitudes, change behavior

Achieve (1) and (2) via behavioral change motivators:•Personalized information (individual, floor, dorm...)•Public commitments •Achievable goals•Social reinforcement•Constant, contextual feedback•Financial incentives

Basic issues with current sites

Lack of real-time feedback•Energy data updated once per week or less.

Incentives not tied to data•Commitments not related to energy data

Energy data feedback not contextual•Global dashboard

(12)

How can we do better? Provide localized, near-real time energy data•Updates every ~10 seconds•Floor by floor metering

Provide highly contextualized information•The system is initialized with users and their locations-maile@hawaii.edu + Frears Hall #402

Commitments and data tied together•Login to specify commitments, these are now associated with a dorm location and energy usage.

(13)

How can we do better? Support energy literacy improvement•Provide incentives for watching videos and passing simple quizzes about energy.-Points for dorm-Badges for individuals

Connect local to global•Provide commitments/data about university, city, state, nation as well as dorm.-HECO grid carbon data in real-time

Support reusability, extensibility, external involvement•Open source licensing•Service oriented architecture•Mix and match components•Multiple display modes (webapp, kiosk, iPhone, etc.)
