If you get an error message like the one below on the screen and the values appear to be correct on the floor and garage screens, try this work around: Go to the garage screen and reenter the garage width. This correctly resets the area of the garage and you should be able to run the calculation. Make sure to save the file. This bug is in EnergyGauge USA version 4.0.01. Our development team will try to include a fix in the next release. Update: This is fixed in version 5 which has been released. If you receive this error, please update your software.
If you check this and you still receive the error please contact us right away and attach the project file in question to your ticket so that we can help resolve this for you.
