University Village Energy Management Information System & Service Design Fall 2008, UC Berkeley

Agenda Project Motivation & Scope Stakeholders, Requirements & Models Prototype: Web Interface Prototype: Free Standing Display Prototype: iPhone Application Future Work 6

Project Scope University Village is a university run "family housing" community of 760 apartments and townhouses in Albany, California. Utility costs are included (hidden) in the rent. An information system is needed to: Give village administrators insights into tenant consumption Allow automation and easier interaction with household appliances Give residents feedback about their consumption Overall Goal: Reduce energy costs

Design Project Where it all started...

Stakeholders Following a bottom-up Energy Management approach, we hoped to put more design emphasis on family and community interests. Tier 1 UC Village Administration, Front Desk and IT Staff Residents Tier 2 UC California Energy Providers (PG&E) Hardware Suppliers Tier 3 State of California Environmental Protection Agencies Energy Conservation Group

Requirements at UC Village Must Have Analyze effectiveness of the system. Classify tenants by usage at the apartment and appliance levels. Make adjusting power consumption in common areas transparent. Lower energy bills. Should Have Improve attractiveness of UC Village for renters Improve public relations Could Have Track and monitor outlier individual units on an on-going basis. Monitor price differences based on peak and off-peak usage.

Requirements of Residents Must Have Feedback on how much energy is being used at multiple levels. Make adjusting power usage transparent. Lower their power consumption/carbon. Should Have Be comfortable. Could Have Allow choices between consuming at peak versus off-peak time.

Business Level Use Cases Make adjustment of the energy consuming appliance's settings as automatic and transparent as possible for the UC Village residents and administration. Provide the UC Village residents and administration with real- time and on-going feedback about their energy consumption. Provide the UC Village residents and administration with improved visibility of the state of their appliances.

System Level Use Case Example Scope: User communicates with a System which in turn communicates with all Appliances in the Apartment of the User.

Service Blueprint

Design Activities User Survey and Diary Competitive Analysis Technology Push Literature Review

Design Requirements  Multi-Platform capability, but Free Standing Display is principal  Overall system awareness of appliances  Disaggregation by user  Personalized visualization  Covering all utilities: energy AND gas, water, and air quality  Predicting usage patterns and use of historic information

Prototype: Mobile Application Mobile application Either alternative to free-standing display or as an extension to one Keep multi-platform focus iPhone works well for implementation of mobile application

Prototype: Mobile Application Justification User survey iPhone app very desirable “Would be really cool” Literature review Free-standing display is important Competitive Analysis No companies focus specifically on mobile applications for energy management Can access energy usage information over the web, alerts over SMS There already exist implementations of free-standing displays such as Wattson and T.E.D. (The Energy Detective) iPhone is very popular

Prototype: Mobile Application Use Scenarios Resident walks out of the house and doesn’t remember if he turned off the lights Checks iPhone to see whether any lights are on If so, then tap on the light to turn it off Coming home from work on a cold winter day, the resident may want the heater turned up to a certain temperature Use the iPhone to adjust temperature to desired level Convenience factor: the resident is lounging on the couch, with a nice cold drink in hand and a warm meal on his lap, then realizes that the light in the kitchen is still on Grabs iPhone from pocket and turns off the light

Prototype: Mobile Application Disadvantages of implementation Not everyone owns an iPhone, despite its widespread popularity It can only be used by one user, namely, the owner of the iPhone Unsuitable for managing dense amounts of information such as setting up and configuring energy management—these operations are intended for a computer
