Hi I have a question, what if I already know the R-values of my walls, windows and roof. Is there a way I can put them in and apply them to each element in the model? I want to test if the rooms will get too hot. I am looking at a house, and am worried that inside it will get too hot in summer. I already have the windows and materials they want to use, but to make the simulation as accurate as possible how can I put these in? Thank you 
Hi @Mackenzie22,
When downloading LBT it comes with a folder called samples.
Here you can find a setup for constructions.
