["Purpose"]
[]
["This model calculates the indoor relative humidity, when outside conditions, home air exchange rates,"]
["and indoor moisture generation rates are known.  It is useful for showing how humidity levels are related"]
["to air exchange rates and to how much moisture is released in a home."]
[]
["Notes on the Model"]
[]
["One general note:  all cells that are colored yellow are inputs to the model and can be changed"]
["by the user.  All other cells contain formulae, and should not be altered by the user."]
[]
["This model assumes that the air pressure is one atmosphere, the typical pressure at sea level."]
[]
["The inputs to the model are explained in more detail in the cell notes.  A cell note is designated"]
["by a red triangle in the upper right corner of the cell.  You can see the note by hovering your mouse"]
["pointer over the cell, if you are using Excel 95 or 97.  If you are using Excel 5, you need to select the"]
["cell and then press Shift-F2 (hold the Shift key down while pressing F2)."]
