Weatherization Assistant 8.9
This is the latest version of the Weatherization Assistant software. Version 18.104.22.168 has added two measures to NEAT: a door replacement measure (with infiltration considerations) and a cool roof measure. The modeling of the heat pump water heater measure has been improved. The Input Summary and Data Collection forms have been updated. Significant additional improvements and corrections in both NEAT and MHEA are included. See the Update History
for a more detailed listing of these changes. Use of the optional Geographical Information System
(GIS) to map client's residences requires an additional download and installation of two files. Click on the links below to download the latest release of Version 8.6 and associated materials for this version:
