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

Stakeholders

Following a bottom-up Energy Management approach, we hoped to put more design emphasis on family and community interests.

Requirements at UC Village

Must HaveAnalyze 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 HaveImprove attractiveness of UC Village for renters Improve public relations

Could HaveTrack and monitor outlier individual units on an on-going basis.Monitor price differences based on peak and off-peak usage.

Requirements of Residents

Must HaveFeedback 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 HaveAllow 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.

Prototype: Mobile Application

Mobile applicationEither alternative to free-standing display or as an extension to one

Keep multi-platform focus

iPhone works well for implementation of mobile application


JustificationUser survey

iPhone app very desirable “Would be really cool”

Literature reviewFree-standing display is important

Competitive AnalysisNo 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


Use ScenariosResident walks out of the house and doesn’t remember if he turned off the lights

Checks iPhone to see whether any lights are onIf 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


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
