Just adding to Daric?s excellent summary:
Certain state, city, and utility incentive program standards also prescribe unique fractional schedules and/or peak loads (W/ft2) for people and misc loads (based on primary building occupancy type), but sometimes these are wholesale copied/pulled from the same schedule sources Daric cited below. You?ll find the NREL reference building
The last resource that comes to mind is Fishnick - https://fishnick.com/cecplug/ . This is specific to defining kitchen & food service process/equipment loads. Not applicable for every building energy model but on the occasion you need to ?go deep? on kitchens it?s worth perusing.
I hold the opinion these ?standard? schedules are in many cases ?good enough,? certainly for prescribed modeling efforts and new construction (when real-world schedules are not yet knowable), and even for calibrated efforts where model outputs require a quantified degree of certainty/accuracy? I say ?good enough? because these schedules generally fall within a ?reasonable range of realities.? In the similar vein, I would observe that schedules generated by the eQuest wizards (which procedurally ?weight? a similar library of occupancy-specific schedules based on the diversity of space occupancies assigned per shell) again often fall well inside of a probable range of reasonable approximations for interior (people/light/equipment) load scheduling.
If however you wish to go further, as I?d advise in consideration of an ECM critically dependent upon / sensitive to a fractional schedule, then you will want to put more thought into tweaking standard/library schedules, or else building a project-specific schedule from scratch.
I have had a lot of luck (with a sprinkling of misfortune as well) learning to deploy data loggers of various sorts to track real world plug and process loads (among other things). Such measurement data can be converted via with Excel pivots and EMIT to generate fractional schedules directly push-able into calibrated eQuest modeling efforts. Would I recommend it? YES. Even if you only rarely this sort of kit, the experience of exploring ?where the sidewalk ends? for in-depth fractional schedule development is valuable. I found the experience enabled me to realize certain challenges were surmountable that would have seemed intractable otherwise. There?s a story or two in here for another day, but for now I guess I?ll sign off with the following: ?Standard/Library schedules are often good enough, but sometimes are not. Recognizing/Intuiting when the standard is not good enough is a skillset you can accelerate with exposure to deploying loggers and analyzing/utilizing their measurements.?
