It seem very low, real consumption depends what is being done in that office - maybe if the desks are big, and each one has nothing more than one chrome book style laptop and a very small reading lamp, and telephones are powered separately, or of it is a hot desk facility where half of them are unoccupied.
Even if that is true, if every third desk needs a printer copier or shredder and a few folk want twin monitors you could easily exceed that. Sitting here at home. I have two of these dell monitors at 75 watts each, and about 100W of dell laptop and its powered docking station, a dect phone and cradle at 12W or so and my installation is very modest compared to my wife as an senior accountant who has more screens, a dedicated laser printer, and a network hub.
Do not allow any further diversity, and in your shoes, I'd query if it is really correct.
Lighting on the desk surface will be perhaps 300 lux if work is only done on computer, rising to more like 500 where there are paper documents to be read as well. Relating that to circuits and watts will depend on lighting fitting types and locations.
