Now working on Sense Tecnic support for MEE. See:http://pspi.magic.ubc.ca/code/index.php/p/sts/

Ideas on very simple model for collecting points:

Assumptions

• users will not enter data that gives them less points overall; they should always get positive points for participation.
• anything entered will increase your points because of participation points.
• If the activity entered doesn't contribute to sustainability, you get zero on top of participation.
• weights for points needs to be determined with testing.

Energy - Power

Calculate kWh for the day using automatic sensor, or user input. If there is no user input for the day, then they get the average. Calculate the difference in power use from the previous day, and from the average

If a difference is positive (i.e. used more than previous or average), then the difference is zero to prevent getting negative points

points += weight1 * -differencePrevious;

points += weight2 * -differenceAverage;

weight1 = weight for points given by improving on your previous results. weight2 = weight for points given by beating the average

Weights can be constants for now, but perhaps in the future can also depend on how performance compares to averages?

Transportation

points += walkNoCar * weightWalkNoCar;

points += walkCar * weightWalkCar;

points = walkCar * weightWalkNoCar;

points += walkCar * weightWalkCar;

walkNoCar means that you wouldn't have taken the car anyway, walkCar means you would have taken the car.

Can be similar for biking and transit.

Consumption

points += weight1 * numProductNoPackage;

points += weight2 * numProductRecyclable;

points += weight3 * numRecyclable;

numProductNoPackage, etc. is the number for that day.

Participation

points += weight * numManualEntries

where numManualEntries is the number of entries that day.

Meeting to provide feedback on overall requirements (what I can remember)

- need overall page flow - need to drill down on data that will be collected - need specifics on visualizations needed - Vince wants to rethink aspects of the project to bring it in line with what he wants to do with his masters. E.g. reconsider main visualizations, and social networking aspects. - settled on what data to collect: Energy, Transportation, Consumption and Participation subject to change depending on point processing model.

Ivy to incorporate feedback so far for Thursday. Vince to work on model for generating points. Mike will start prioritizing Sense Tecnic requirements based on this. Vince will also work on aligning project with Masters and taking over lead role.

• Started work on requirements document on the Wiki. Created outline and sample feature.
