Hi,'How can I calculate total area of windows in the exterior walls divided by total net area of outside of exterior walls? I get a result only by using the one windows and wall area but it's the inside of the wall which is not what I want. When dividing window ara by wall aoutside face area I get no result (property as number and available for all...)

Hi Mats,

Can you copy your code or the part of the code that is not working?
The one below seems to work fine for me (Data Type: Number).
Code: Select all
{Property:Wall/Area of the Windows} / {Property:Wall/Gross Surface Area of the Wall on the Outside Face}
