Subject: December Contractor Update - Merry Christmas!
Below are; Some metrics, Competing for results, and a much better way of managing data:
You also may know that I feel this program needs to move toward a new competitive metric - one of published ability to deliver savings projected. This will do for our industry what MPG ratings did to the auto industry, it will create incentive to excel around a metric that benefits the consumer and adds credibility to our promises. It will allow us to market based upon truth and accountability, not smoke, mirrors and hope. Sell to reason, not fickle emotion.
Tracking before and after energy would be ideal but right now there is an access problem to energy consumption data "after" improvements. Until we can solve this, do we have anything that might indicate what results to expect by contractor? Well, we do have access to "reported energy use before" and "modeled energy use before".
Certainly someone who uses 1000 therms who has a model showing they use 2000 therms will save 40% is not likely to see 800 therms savings.
Do No Harm. To roll out a ranking or registry without contractor understanding of what is coming is likely to cause harm, so providing this interim step information in a format indicating what will eventually be public information provides opportunity to adjust behavior and policies ahead of time. Forewarned is forearmed.
Below is a representation of the data available, and an idea of what a realization ranking might look like. Those closest to the line have the models that most closely represent consumption of the homes they audit, and those further to the left tend to overstate consumption: (might need Chrome to view)
There is a lot that can be done here, for example these numbers could be run quarterly to show who is improving and who is sliding. You can't manage what you don't measure, and this should be managed. Nick Taylor is working on making these numbers so people can dig in and understand how to improve results.
