My contractor wants glass areas / open areas from all of the Windows in our project. When I go to the Instance Properties there is no Area Value as there would be for a Wall, for example. I am trying to edit the family for the window and I added the Area parameter, but it isnt calculating any area. How would I do something like this?

I would suggest to create a shared parameter in the window family. Area parameter should be able to achieve by width x height and use "area" as a shared parameter (fill in the value in the formula)

once you are back in the project, you should be able to schedule the area from the window schedule.

use the value as well as the wall area to do your cals.

It will be a bit of manual process anyway since Revit doesn't automatic calculate that

You might need to set up extra parameter for the walls to tell which side of the wall area/window area to be calculated.

You also have an option to do calculated values through schedules, but that means all of your window paramters will need to be schedulable in the first place.  What is glass area exactly; from the inside faces of frames?  If so, then a height*width parameter may not be sufficient, depending on how precise your values need to be.

If you are able to schedule frames, then calculating the totals in the schedule will work well, especially if you have multiple frame widths, and/or multiple window families.  If you have to add a shared paramter to each window file (say you have 8-10 loaded into the project) this can be a little time consuming.  Calculating totals through schedules can save this time but only if all window family are consistently built (e.g. paramter names, paramter assignment, etc.)

pchans suggesstion and mine will, in principle, accomplish the same thing.  This is just another tool you have at your disposal.

Rough opening of the window is fine for glass area. 

I found a discussion that helped me solve this here:

I am just struggling with the Family Properties 'Types'

Okay I add a Parameter, I get that... and there are both Family and Shared parameters... Obviously I need a Shared parameter for the area values to appear in schedules. When Shared Parameter is selected... the window is all greyed out but the 'Select' button. Now I am trying to find a Shared Parameter File... and this is where I am completely lost and opens a whole new world for me in Revit. What is a Shared Parameter File? Where do I find them? How do I make them? The discussion link that helped me out included one in the zipped file. Which is great and all but I want to know how you go through the process of making one for future use. I open the one provided from the AUGI discussion and its a bunch of text and generate text and was thinking... how do that?

When you are lost, look in your HELP first:>  Setting Up Shared Parameter Files  simply search <parameter> and start learning.

I was struggling with this and found this link (above) in which I added a comment too. Let's see if 2014 answers our questions.

If you have the same window over and over you could calc the area for one window and multiply by how many windows you have
