Hello,

I have built a model with one ground floor and a basement. The ground floor is larger than the basement, therefore it has two parts. One part is adjacent to the basement and another part is in contact with the ground.

However, every time i check the floor area of the ground floor, it only includes the floor area that is adjacent to the basement and exclude the area that is in contact with the ground. Therefore, the ground floor area used for simulation is smaller than the actual area, which I think may cause a big difference in simulation since the internal load, EUI are calculated based on the floor area. In addition, it is not allowed for us to manually input the floor area of the ground floor.

Could anyone tell me how to solve this problem? Thanks!

How are you checking the floor area of your ground floor?

There are 2 types of floors in the VE... Internal floor/ceiling and Ground/exposed floor. Your ground floor will have floor area in each of these categories and I'm fairly certain this is what you are seeing.

What I'm not sure of is where you are looking that is displaying only the internal floor/ceiling area. In terms of internal loads & the simulation, I can assure you that the entire area of the geometry you have drawn is used. Whether the floor touches the ground or an adjacent space may change the category that identifies the floor, but any W/ft2 or people/ft2 gains are still applied to the total area.
