[Pw_forum] highest occupied state

Dear users,
I would like to calculate the highest occupied state energy of a
nano-structure with respect to the vacuum level.

I took vacuum about 20A, if I increase the vacuum the total energy and gap
do not change but the highest occupied and the lowest occupied states will
be shifted up with a same amount.
I can't understand the meaning of this energy shift,
how can I calculate these energy respect to the vacuum level?

I really appreciate your help in advance.
