DAX: Calculate Percentages

I have a data model similar to the below:

Building Occupier Area
building 1 occupier1 10000
building 1 occupier 2 15000
building 2 occupier 3 10000
building 3 occupier 4 10000
building 3 occupier 5 20000

So essentially, any building can have one or more occupiers. What I am wanting to work out is the percentage each occupier has for the building they occupy. So in the above example, occupier 1 has 10000 sqft of an 25000 sqft building, so they occupy 40% of building 1. How can I calculate that across the entire dataset.

Need Help

Hi s_mccafferty ,

Here we can create a measure to work on it.

Measure =
VAR oc =
    CALCULATE ( SUM ( Table1[area] ) )
VAR al =
    CALCULATE ( SUM ( Table1[area] ), ALL ( Table1 ), VALUES ( Table1[Building] ) )
RETURN
    DIVIDE ( oc, al )
