Utility Peak Demand Summary
Utility Peak Demand Summary
The Utility Peak Demand Summary report provides you with a monthly profile of the peak demand for each fuel type utilized on a project. The report breaks the monthly peak demand down to usage type categories including Heating, Cooling, Interior Lighting, Exterior Lighting, Interior Receptacles, Exterior Equipment, Fans, Pumps, Heat Rejection, Humidification, Heat Recovery, Water Systems, Refrigeration, and Generators. This report also provides when the monthly peak occurs. The graph depicts the tabular data, with colors noted in the legend.
In the example below, the peak electric demand of the small building is 18 kW in January and 43.7 kW in July. In July, 28.5 kW of the 43.7 kW was due to cooling equipment. The peak kW does not account for high amp draw upon motor start up; this means the engine intrinsically assumes all devices have soft starts.
Summary of each category:
|
Heating:
|
|
All heating equipment including consumers associated with their equipment libraries. For example, electric heating coils, electric boilers, boiler parasitic loads. This does not include fans or pumps defined separately in the loop.
|
|
Cooling:
|
|
All cooling equipment including consumers associated with their equipment libraries. For example, DX cooling coil and its crankcase heater, air cooled piece of equipment and its condenser fan, water cooled chiller, cooling mode of operation for a heat pump. This does not include fans or pumps defined separately in the loop.

|
Interior Lighting:
|
|
Interior lighting defined in the internal load properties on the Create Building tab.
|
|
Exterior Lighting:
|
|
Exterior lighting defined in the Create Site tab.
|
|
Interior Equipment:
|
|
Miscellaneous equipment defined in the internal load properties on the Create Building tab.
|
|
Exterior Equipment:
|
|
Exterior Fuel Equipment from the Power-Using Objects toolbar on the Create Site tab.
|
|
Fans:
|
|
All fans (supply, return, OA, exhaust) but does not include condenser fans.
|
|
Pumps:
|
|
All pumps in loops defined in Create Plants.
|
|
Heat Rejection:
|
|
This includes both the condenser fan and the basin heater for condenser loops defined in Create Plants.
|
|
Humidification:
|
|
Humidifiers defined in Create Systems.
|
|
Heat Recovery:
|
|
Energy consumption associated with airside energy recovery devices. This is not the amount of energy recovered. This does not include waterside heat recovery.
|
|
Water Systems:
|
|
Exterior Water Equipment from the Power-Using Objects toolbar on the Create Site tab.
|
|
Refrigeration:
|
|
Not used.
|
|
Generators:
|
|
This is the fuel used by Internal Combustion Engine and Combustion Turbine from the Power-Generating Objects toolbar on the Create Site tab. This is the fuel consumed, not the generator power.
|
|
Electricity Produced:
|
|
This is the total energy produced by all generators on the Create Site tab.
