Group – Exterior Energy Use Equipment[LINK]
To facilitate the reporting of exterior consumption (to the building’s heat balance/loads considerations), several objects have been included. The consumption related to these items will appear on meters specific to the items.
Exterior:Lights[LINK]
This descriptive name allows the values of exterior lights consumption to appear in the “normal” output variable list as well as the meters. It cannot be blank nor can it be duplicated by other Exterior:Lights statements.
Field: Schedule Name[LINK]
A schedule will allow the exterior lights consumption to be operationally different, hour to hour as well as seasonally. Fractional values in the basic schedule will be applied to the design level field below.
Field: Design Level[LINK]
This field (in Watts) is typically used to represent the maximum electrical input to exterior lighting fixtures that is then multiplied by a schedule fraction (see previous field). In EnergyPlus, this is slightly more flexible in that the lighting design level could be a “diversity factor” applied to a schedule of real numbers. Note that while the schedule value can vary from hour to hour and seasonally, the design level field is constant for all simulation environments.
Field: Control Option[LINK]
This field is used to determine how the exterior lights are controlled. There are currently two options, ‘ScheduleNameOnly’ and ‘AstronomicalClock.’ If this field is omitted or left blank then the program will default to Schedule Name Only mode. The ‘ScheduleNameOnly’ mode dictates that the exterior lights always follow the schedule named in the field above. The ‘AstronomicalClock’ mode dictates that despite what the schedule indicates, the exterior lights will not run when the sun is up. Using the Astronomical Clock mode makes it simple to model exterior lights that are controlled by a photocell or other controller that ensures that outdoor lights will not run during the daytime. However, the Astronomical Clock control works off of the position of the sun and therefore does not operate exactly like a photocell. During the night, the schedule values are still applied in the usual way.
Field: End-Use Subcategory[LINK]
Allows you to specify a user-defined end-use subcategory, e.g., “Grounds Lights“,”Facade Lights“, etc. A new meter for reporting is created for each unique subcategory (ref: Output:Meter objects). Subcategories are also reported in the ABUPS table. If this field is omitted or blank, the lights will be assigned to the “General” end-use subcategory.

Exterior:Lights,
OutsideLights, !- Name

Output for exterior lights appears in three possible places. It will appear on two meters (Electricity:Facility and ExteriorLights:Electricity) as well as in its own designated value in the standard output file.

Exterior:FuelEquipment[LINK]
This descriptive name allows the values of exterior equipment consumption to appear in the “normal” output variable list as well as the meters. It cannot be blank nor can it be duplicated by other Exterior:FuelEquipment or Exterior:WaterEquipment statements.
Field: Fuel Use Type[LINK]
This field designates the appropriate meter for the exterior fuel equipment. Valid fuel types are: Electricity, NaturalGas, PropaneGas, FuelOil#1, FuelOil#2, Diesel, Gasoline, Coal, Steam, DistrictHeating, DistrictCooling, OtherFuel1 and OtherFuel2. The fuel type triggers the application of consumption amounts to the appropriate energy meters.
Field: Schedule Name[LINK]
A schedule will allow the exterior lights consumption to be operationally different, hour to hour as well as seasonally. Fractional values in the basic schedule will be applied to the design level field below.
Field: Design Level[LINK]
This field (Watts) is typically used to represent the maximum input to exterior fixtures that is then multiplied by a schedule fraction (see previous field). In EnergyPlus, this is slightly more flexible in that the design level could be a “diversity factor” applied to a schedule of real numbers. Note that while the schedule value can vary from hour to hour and seasonally, the design level field is constant for all simulation environments.
Field: End-Use Subcategory[LINK]
Allows you to specify a user-defined end-use subcategory, e.g., “Fountains”, etc. A new meter for reporting is created for each unique subcategory (ref: Output:Meter objects). Subcategories are also reported in the ABUPS table. If this field is omitted or blank, the equipment will be assigned to the “General” end-use subcategory.
IDF Examples:
Exterior:FuelEquipment,OutsideGasEq,Gas,ON,1000;
Exterior:FuelEquipment,OutsideCoalEq,Coal,ON,1000;

Exterior:FuelEquipment,OutsideFuelOil2Eq,FuelOil#2,ON,1000;

Exterior:WaterEquipment[LINK]
This descriptive name allows the values of exterior equipment consumption to appear in the “normal” output variable list as well as the meters. It cannot be blank nor can it be duplicated by other Exterior:FuelEquipment or Exterior:WaterEquipment statements.
Field: FuelUseType[LINK]
For Exterior:WaterEquipment, only “Water” is current allowed for this field.
Field: Schedule Name[LINK]
A schedule will allow the exterior water consumption to be operationally different, hour to hour as well as seasonally. Fractional values in the basic schedule will be applied to the design level field below.
Field: Design Level[LINK]
This field (in m3/s) is typically used to represent the maximum volumetric flow for water fixtures that is then multiplied by a schedule fraction (see previous field). In EnergyPlus, this is slightly more flexible in that the exterior water equipment design level could be a “diversity factor” applied to a schedule of real numbers. Note that while the schedule value can vary from hour to hour and seasonally, the design level field is constant for all simulation environments.
Field: End-Use Subcategory[LINK]
Allows you to specify a user-defined end-use subcategory, e.g., “Landscaping”, etc. A new meter for reporting is created for each unique subcategory (ref: Output:Meter objects). Subcategories are also reported in the ABUPS table. If this field is omitted or blank, the equipment will be assigned to the “General” end-use subcategory.
