The Weatherization Assistant is a suite of four audit tools developed by the Oak Ridge National Laboratory to specifically help states and local weatherization agencies implement the US Department of Energy Weatherization Assistance Program, although it can be used by utilities and other home energy professionals.

• The National Energy Audit Tool (NEAT) – For site-built, single-family homes.

• The Manufactured Home Energy Audit (MHEA) – For mobile homes.

• The Multifamily Tool for Energy Audits (MulTEA) – For multifamily buildings.

• The Health and Safety Audit – For single-family homes (including mobile homes) and individual dwelling units in low-rise multifamily buildings that are being weatherized.

There are currently two versions of the Weatherization Assistant: a computer-based application that provides access to NEAT and MHEA, and a web-based application that provides access to MulTEA and the Health and Safety Audit.
