is there a possibility to enter the occupation planing or the density of occupancy in beopt if not how beopt takes into consideration the occupation ?

There is an equation for number of occupants as a function of the number of bedrooms.

You can modify this equation in the _processOccupants() method in \modeling\sim.py:

occ.num_occupants = 0.63 + 0.92 * unit.num_bedrooms for single family or

occ.num_occupants = 0.87 + 0.59 * unit.num_bedrooms for multifamily

Note that this only adjusts the heat gain of the occupants. Energy use for appliances, hot water use, etc., will still be derived by number of bedrooms.

So, an easy way to change the occupant density is to change the number of bedrooms. However this only has the resolution of five discrete options: 1,2,3,4,5.

is there a schedule of occupation because the occuppants are not always at home and that has an influence on the results. i also want to know how much of the power dissipated per person that beopt takes in the calculations

That can be found in Figure 25 of the House Simulation Protocols document accessible via the BEopt help menu.
