Software/Versions Affected:

In the two installations dated  5/18/2005 and 8/26/2005, MEC Zones 18 and 19, used in some of the very extreme heating climates in the United States, will cause an error in the simulation, because some of the constructions with high insulation values have not been defined in the program, in particular, R21 and R28 frame and concrete block walls, and R49 ceilings. The current installation downloadable on the web, dated 9/20/2005, fixes this problem with a corrected file. If you have a previous installation of RESFEN5, download this zip file, which contains the corrected file, NFRC900.LIB, dated 9/20/2005. After downloading the zip file onto your computer, unzip the file into the C:\Program Files\LBNL\RESFEN5\Data directory (assuming you installed RESFEN5 in the default directory) — you can overwrite the old file of the same name. The date of the corrected RESFEN5Windows.dat file is 9/20/2005.
