Revit reports load calculations in various forms.
The load classification values are:
For a load classification on a panel
- Total connected load = the sum of all loads attached to the panel (directly or to subpanels) from connectors assigned to that load classification
- Demand Load = the result of the specified demand factor being applied to the sum of all loads attached to the panel (directly or to subpanels) from connectors assigned to that load classification Note: The demand factor is specified in the Load Classifications dialog. See Creating a Load Classification.
For a load classification group on a panel
- Total connected load = the sum of all loads attached to the panel (directly or to subpanels) from connectors specified as part of that load classification group
- Demand Load = the sum of the demand loads for each load classification for connectors specified as part of the load classification group
For all loads on a panel
- Total connected load = the sum of all loads attached to the panel (directly or to subpanels)
- Demand Load = the sum of all demand loads (for all load classifications) on the panel
Example of connected loads and calculations
For Panel C

LC Group Lights
Total Connected Load (Panel C) = (4+5+6+7)
Total Demand Load (Panel C) = DFBob * (4) + DFMary * (5) + DFFrank * (6+7)
- Total Connected Load = 4
- Total Demand Load = DFBob * (4)
- Total Connected Load = 5
- Total Demand = DFMary * (5)
- Total Connected Load = (6+7)
- Total Demand Load = DFFrank * (6+7)
- Total Connected Load = (5+6+7)
- Total Demand Load = (Panel C) = DFBob * (4) + DFMary * (5) + DFFrank * (6+7)
For Panel B

Total Connected Load (Panel B) = (4+5+6+7+8+9+10)
Total Demand Load (Panel B) = DFBob * (4+8) + DFMary * (5+9) + DFFrank * (6+7+10)
- Total Connected Load = (4+8)
- Total Demand Load = DFBob * (4+8)
- Total Connected Load = (5+9)
- Total Demand = DFMary * (5+9)
- Total Connected Load = (6+7+10)
- Total Demand Load = DFFrank * (6+7+10)
- Total Connected Load = (5+6+7+9+10)
- Total Demand Load = (Panel C) = DFBob * (4) + DFMary * (5) + DFFrank * (6+7)
For Panel A

LC Frank
LC Group Lights
Total Connected Load (Panel A) = (1+2+3)
Total Demand Load (Panel A) = DFBob * (1+2) + DFMary * 3
- Total Connected Load = (1+2)
- Total Demand Load = DFBob * (1+2)
- Total Connected Load = 3
- Total Demand = DFMary * (5+9)
- Total Connected Load = 0
- Total Demand Load = 0
- Total Connected Load = 0
- Total Demand Load = 0
For Panel MCB

Total Connected Load (Panel MCB) = (1+2+3+4+5+6+7+8+9+10)
Total Demand Load (Panel MCB) = DFBob * (1+2+4+8) + DFMary * (3+5+9) + DFFrank * (6+7+10)
- Total Connected Load = (1+2+4+8)
- Total Demand Load = DFBob * (1+2+4+8)
- Total Connected Load = (3+5+9)
- Total Demand = DFMary * (3+5+9)
- Total Connected Load = (6+7+10)
- Total Demand Load = DFFrank * (6+7+10)
- Total Connected Load = (5+6+7+9+10)
- Total Demand Load = DFMary * (5+9) + DFFrank * (6+7+10)
Calculations are performed per panel. There are two types of load: Total Connected, and Total Estimated Demand. For each of these types, the desired calculations can be per panel (all loads), per load classification, or per load classification group.
For Total Connected Load on a panel, all loads of the same load classification connected below that panel (to either the panel directly, or to any child or grand-child panels connected up to the panel) are summed.
