Calculating Window Wall Ratio (WWR) for a project

Window to wall area ratio (WWR) is an important metric for all architectural projects that put an emphasis on sustainability. Deriving this information from a Revit model using native tools like schedules is surprisingly difficult. The following blog post outlines our firm’s attempt at garnering this information from our projects using Dynamo and Excel. We are happy to share it with anyone interested in testing this tool. Read more about this.

Download the Dynamo, Excel and instruction files from here.


Those who have tried this tool, or will try it, we will appreciate receiving feedback about improving it, or about your general user experience.


It isn’t really relevant to me- but thanks for sharing !
