Load Calculations
 
 
 

Revit MEP reports load calculations in various forms.

The load classification values are:

For a load classification on a panel

For a load classification group on a panel

For all loads on a panel

Example of connected loads and calculations

For Panel C

LC Bob

LC Mary

LC Frank

LC Group Lights

Total Connected Load (Panel C) = (4+5+6+7)

Total Demand Load (Panel C) = DFBob * (4) + DFMary * (5) + DFFrank * (6+7)

For Panel B

LC Bob

LC Mary

LC Frank

LC Group Lights

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)

For Panel A

LC Bob

LC Mary

LC Frank

LC Group Lights

Total Connected Load (Panel A) = (1+2+3)

Total Demand Load (Panel A) = DFBob * (1+2) + DFMary * 3

For Panel MCB

LC Bob

LC Mary

LC Frank

LC Group Lights

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)

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.
