Ilyas, Standards vary widely from country to country (and even state/province to state/province) depending on the extent (or existence) of energy codes. In the US ASHRAE standard 90.1 gives recommended limits for lighting wattage in commercial buildings. Some areas adopt this standard as an energy code and those limits become required limits. Corridors are recommended to be lit with no more than 5.4 W/m2. Offices are recommended to be lit no more than 11.8 W/m2. No recommendation is given for a limit to equipment gains or occupancy gains because these are too dependent on the use of the room. Typically, though, it is safe to assume 16.1 to 21.5 W/m2 for plug load gains. ASHRAE publishes gains from occupants performing various tasks. TRNBuild shows some of these values in the occupancy gains screen if you click to view the tables.
Residential numbers are more difficult to track down. A program in the US called Building America has some useful data. I do not know what resources are available for the European context although I would be quite surprised if they were not more extensive than what is available in the US. kind regards, David
