LEED the Way with Revit

So you’re working on a renovation project and going for LEED certification, congratulations! You’ll eventually need to calculate total surface areas for various elements in your design and compare them between what is being reused, demolished, and new for material reuse credits.
Here are a couple of Revit tricks to gather these calculated values and display them in a nice and easy to read set of schedules. You will need to create separate schedules for New, Demo and Existing for proper comparisons.
First create a new text shared parameter named something to the effect of “LEEDScheduleFilter” and bind it to all categories in your model. This parameter will be the target of any schedule and view filtering for each of our required conditions. This parameter also allows us to filter out specific elements that exist in the facility model but are not part of the renovation scope (very important).

Bind this new parameter to all categories in your model.

Some families may need to be modified to schedule calculated facial areas and volumes (doors, casework, etc.).




Now that this parameter is accessible as an instance parameter to all categories in the model, we can begin to enter filtering data for the categories that we need to calculate surface areas for.

I typically setup a few working views so I can visualize the data that I am entering into my elements by using filters. Create a new view and name it something like “LEED Surface Areas Level 1” and set it to “Hidden Line.” Then in Visibility Graphics, create filters in the Filters tab for:
·         Included Walls Exterior
·         Included Walls Interior (Area X 2)
·         Included Casework
·         Included Doors
·         Included Ceilings


Apply these filters to the view and set a color for each of them so you can tell which elements have “qualified data” applied to them. Setup your schedules to use the same filtering rules as your filter views.


As you know, LEED


Here are some fairly self explanatory images for setting up your schedules:
