I'm attempting to model a school in eQuest and my fan energy seems much too low. In searching for the source of the low fan energy I noticed that the input screen in eQuest for AHU fan static pressure lists "Static in WG" for units, while the SV-A output report lists the units for the AHU fan in "IN-WATER."

What throws me is that the value in both is exactly the same: that is, I've entered a fan static pressue of 0.4 inches hg in eQuest, and the static pressure value which appears in the SV-A report in inches water is also 0.4.

Has anyone encountered this oddity? Anyone aware of what the source might be? I don't yet have a good grasp of how the unit conversions work between eQuest and DOE...

"WG" stands for water gauge, which is synonymous with inches of water. It is not "hg" or mercury.

Wowsers one of the dumbest mistakes of all time. Thanks a lot in any case!
