How can I plot monthly consumption and demand data?

 Results Visualization with monthly data

In EnergyPlus and Simergy there exists a large range of output variables and output meters. All of which can be either defined in the output requests set template or added to the InjectIDF.idf file.

Typical electricity or gas meters at the facility and building level are as follows:

Electricity:Facility	Electricity:Building
	Electricity:HVAC
	Electricity:Plant

 

To better understand which meter sums up other meters, you can refer to the “eplusout.mtd” file that contains all relevant meters for each specific run.

More specific electricity meters are:

Electricity:Facility	Electricity:Building	InteriorEquipment:Electricity
		InteriorLights:Electricity
	Electricity:HVAC	Fans:Electricity
		HeatRecovery:Electricity
		Humidifier:Electricity
		Coils:Heating:Electricity
		Coils:Cooling:Electricity
	Electricity:Plant	Pumps:Electricity
		Cooling:Electricity
		Heating:Electricity
		HeatRejection:Electricity
		Refrigeration:Electricity
		WaterSystems:Electricity
		Cogeneration:Electricity
		WaterHeater:WaterSystems:Electricity
		WaterSystems:Electricity
	ExteriorEquipment:Electricity
	ExteriorLighting:Electricity

 

 

 

Some example for gas meters are:

Gas:Facility	Gas:Building	InteriorEquipment:Gas
	Gas:HVAC	Heating:Gas
		Cooling:Gas
	Gas:Plant	Boilers:Heating:Gas
		Cogeneration:Gas
		Refrigeration:Gas
		WaterHeater:WaterSystems:Gas
		WaterSystems:Gass
	ExteriorEquipment:Gas

 

In order to output electric demand the following variables can be added:

Facility Total Electric Demand Power	Facility Total Building Electric Demand Power
	Facility Total HVAC Electric Demand Power

Similar to before the first variable is the sum of the other two (building and HVAC).

 In Simergy Version 4.0, a new output request set template is available that contains all mentioned meters and variables (Electric/gas consumption and demand).

                                                                                                    Templates workspace – Sample output request set template

 

This template contains one or more output request sets which are also editable, so the user can add or remove meters and output variables. We recommend leaving the Frequency of reporting at its default “hourly” value. The interval is very easily adjusted in the Results Visualization workspace.

 

 

                                                                                                 Library workspace – Sample output request set

Once you assign the output request set to a simulation configuration in the simulation workspace, the variables and meters get added to the IDF file on export. After a successful simulation run they are accessible via the Result Visualization workspace. Below are two bar chart examples showing total electrical demand and total electricity on a monthly interval as well as electrical and gas consumption.
