What data will be required at the state level? The local?
A vast array of data on household characteristics, both housing and demographic, weatherization measures applied, energy bills from before and after weatherization, client education, audit procedures, and crew training, to name just a few, will be gathered as part of the evaluation. The purpose is to both to assess program results and to understand the underlying causes of differing levels of performance.
Those interested in a fuller understanding of the scope and scale of the questions are advised to examine the National Evaluation Plan on the ORNL web site:
