Cooling load calculations for hotel rooms

When performing cooling load calculations of an hotel room, do I consider the toilet as part of the area being cooled as it is at negative pressure with respect to the room and cooled air will flow from the room into the toilet. Or should I perform and the load of the room separately and add losses from the room through the partition wall.

The toilet area is part of the area being cooled, so you need to consider it. You will need to account for the air lost in the restroom. Any air the bathroom fan pulls out, comes in from somewhere, and it has to be conditioned/accounted for.

Or should I perform and the load of the room separately and add losses from the room through the partition wall.
I'm not sure what you are asking here. To get a good load calculation, you will have to account for all the gains/losses for the whole room.

i meant losses to the toilet through the partition wall, If I am considering the cooled area to include the toilet , I would not consider the partition wall separating the toilet and the room because I am assuming the toilet and room are at the same temperature.

Ordinarily, I wouldn't either, unless the bathroom is a separate, unique source of heat/cold, or something unusual. In this case, the bathroom fan air needs to be accounted for, and the volume in the bathroom should be included.

The toilet and room are in the same envelope.
