# Energy simulation without geometry

Hi all,

I want to do preliminary calculation how much energy will be consumed just inputting following parameter

- Lighting Power Density [W/m2]
- Small power [W/m2]
- Zone area [m2]
- Schedule

Since the HVAC consumption is not critical in this project, we want to skip the procedure to construct the geometry and just input area information to get preliminary result.

Are there any example file or page I can refer to how to do that?

Why is a simulation necessary? You can do it with Excel.
