Software HERS-ST v4.5 and HERS-ST v4.5 Lite (release date June 2011)
HERS-ST 4.5 Lite downloads quickly (39 MB as compared to 268 MB) and is the same as the full version except that it does not contain the GIS shape files for all the States. The shape files are not necessary for using HERS-ST unless you want to see the county, city and water delineations in the GIS element of the software.
Please note that the Office of Asset Management and the HERS-ST Program Manager do not support customized versions of the HERS-ST software. Only software downloaded from this website or received from the HERS-ST Program Manager will receive free, full technical support from the Office of Asset Management and its contractors.
