The Weatherization Assistant is an energy audit software tool developed for the DOE Weatherization Assistance Program by the Oak Ridge National Laboratory.

In addition, Version 8 of the Weatherization Assistant provides expanded optional capabilities that are useful in implementing and administering weatherization programs, including agency-related contact information, client data intake, recording of health and safety issues, recording of diagnostic measurements, work orders, status tracking, simplified cost accounting, inventory control, report generation, site mapping, and digital photo storage.
