Over our six years we've had a combination. We do a combination of energy modelling to determine what we believe is going to be the energy savings, and then we actually look at users' consumption data from utilities. Those are the savings that we report. Some of the funders, some of the cities, and some of the utilities have done their own independent studies. I believe Energy Efficiency Alberta is also planning to do that.
