Dear Bohdan,

If I don't forget any prefactor, this is the definition of the Band energy:

E_band = \sum_{k i s}  weight(k) * occ(e_{k i s}) * e_{k i s}

where k stands for k-point, i for band index, s for spin.
occ is 1 for occupied states and 0 for empty ones (or a smeared function 
for metals).
e_{k i s} is the Kohn-Sham band structure within your favorite 
exchange-correlation approximation.
And weight(k) is the weight of the k-point in the Monkhorst-Pach scheme.

Fabien
