Hi all, I’m working on a project where I need to calculate floor areas that fall within 30ft of the exterior walls but only the areas that have views/sightlines to the exterior wall. For some context, this is part of a study for a building pursuing Living Building Challenge certification and we are trying to understand our compliance with the views and daylight requirements.
So far, I’ve been geometrically constructing these viewsheds with filled regions and using these regions to see 1) where they overlap rooms and 2) how much floor area of those rooms falls within the viewshed taking into consideration opaque walls that obscure views. These “partial room” areas along with the rooms falling fully within the viewshed possessing unobstructed views gets me the total floor area in compliance.
Has anyone used Dynamo to streamline this process in the past? I’m trying to think of a good approach to generate and update these fixed-distance viewsheds as the plans continue to develop, either having Dynamo generate the filled region for me to manually pull area numbers or to have it calculate and populate a room parameter with the area falling within the viewshed. Attached is a sample of the filled region approach I’ve been using with the 30’ viewsheds shown in blue.
Any help would be appreciated - thanks!
