Please remember that these numbers are also effected by human habit assumptions as well as 'optimal' manufacturers conditions when generating the initial performance ratings. Predictive modeling is a wonderful combination of art and science, with levels of granularity behaving much in the same way as the diminishing point of returns. Hi Ray,

The final model will take into account all items we have chosen as a whole. We have to figure out what to plug into the final model somehow and this method makes good sense to me. I can't answer the energy star appliance question. Certainly there is a range of energy consumption especially when you are looking at a range of fridge sizes for example. I did give them an itemized list of what I was considering for the home so maybe they took that into account.

Don't you want whole house system modeling done before you make a decision? To ensure that all the individual parts make a greater whole? And since there is variation in the energy star appliances, is the value assuming the minimum? “Each item does not take the other improvements into account, so ultimately the savings for each line item will be less in the final energy model that takes into account all improvements.”
