Hello good morming, I would like to discuss the following example: If the simulation result on building level is, that the end use of lighting is >10% and the end use of user equipment (computers e.g.) is also >10% but I have more than 10 offices in the building with floor lamps (so the end energy use for the two end use types together for each office would be <10%).
- Would it be allowed to meter lighting and user eqipment per office together (so I would have 1 meter for each office which meters the electricity used for the working task)?
- Floor Lamps have a plug. Do they count as lighting or as receptacle eqipment?
Background of my question is, that the seperate metering of the receptacles for floor lamps and the receptacles for user equipment is really cost prohibitive. All offices have the same schedule, the same equipment. The HVAC eqipment will be definitely metered seperately.

In the manual it reads that "End uses can e.g. be grouped by occupancy type" since it allows building operators and energy managers to seperately monitor different space types and account for different energy use patterns. Here we have one space type, one timetable, same Equipment and same energy use pattern...

1. Each end use must be separately metered.
2. Plug in lighting is lighting, not plug load. So when metering lighting and plug loads you would need to estimate some sort of adjustment to both values to account for your plug in lighting. Since it is such a small item I think you would not have to meter it separately but you should be able to account for it when gathering data post-occupancy.
