I am using TRNSYS 18. Currently I am I modeling a building which has a shading effect from external buildings. If I want to add a nearby (adjacent) building that gives shading effect, which component should I use?.
You can use the TRNSYS 3D plugin for Google Sketchup to sketch your building zones, and also to create shading zones. It is not a component per-se, but can be sketched in Google Sketchup.
I have a new TRNSYS course available on Udemy which will teach you all of these skills and a lot more. Check it out here: https://www.udemy.com/learn-trnsys/?couponCode=LEARNTRNSYS_RG
