The strategy has three prongs:
- Dormies can see their daily consumption. That's fast feedback. (That link will disappear at the end of the month, so look now!)
- Residents can compare their current consumption to their numbers from the day or year before (click on the name of a hall to see the graphics). That creates an incentive to improve personal (or in-group) performance.
- Residents can compare consumption to others in other halls, to see who is at the top of the league table. That comparison creates in-group vs out-group competition, which is very powerful.
And remember that these students are NOT facing financial incentives to use less water!
Shahram Javey at Aquacue is looking for financial and other types of support. If you like this, email him.
Bottom Line: People will use less water if they know how much they are using and how much relative to "normal" -- aka, their peers. (Oh, and it doesn't hurt to give financial reminders of high and low consumption :)
