algorithmic modeling for Rhino
I want to know the EP output variables used to calculate the output on the Read EP Results and Read EP Surface Results components.
May I ask if the following list is correct?
May I also ask what the EP output variables are to calculate outdoorAirEnergy?
Thank you very much!
Output variables on the Read EP Results component:
[1] totalThermalEnergy
=
cooling
+
heating
[2] thermalEnergyBalance
=
cooling (-)
and
heating (+)
[3] cooling
=
Zone Ideal Loads Supply Air Total Cooling Energy [J](Hourly)
=
Zone Ideal Loads Supply Air Sensible Cooling Energy [J](Hourly)
+
Zone Ideal Loads Supply Air Latent Cooling Energy [J](Hourly)
[4] heating
=
Zone Ideal Loads Supply Air Total Heating Energy [J](Hourly)
=
Zone Ideal Loads Supply Air Sensible Heating Energy [J](Hourly)
+
Zone Ideal Loads Supply Air Latent Heating Energy [J](Hourly)
[5] electricLight
=
Zone Lights Electric Energy [J](Hourly)
[6] electricEquip
=
Electric Equipment Electric Energy [J](Hourly)
[7] peopleGains
=
Zone People Total Heating Energy [J](Hourly)
[8] totalSolarGain
=
Zone Windows Total Transmitted Solar Radiation Energy
[9] infiltrationEnergy
=
Zone Infiltration Total Heat Gain Energy (+)
and
Zone Infiltration Total Heat Loss Energy (-)
[10] outdoorAirEnergy
= ???
[11] natVentEnergy
=
Zone Ventilation Total Heat Gain Energy (+)
and
Zone Ventilation Total Heat Loss Energy (-)
[12] operativeTemperature
=
Zone Operative Temperature
[13] airTemperature
=
Zone Mean Air Temperature
[14] meanRadTemperature
=
Zone Mean Radiant Temperature
[15] relativeHumidity
=
Zone Air Relative Humidity
[16] airFlowVolume
=
[infiltrationFlow] Zone Infiltration Standard Density Volume Flow Rate
+
[natVentFlow] Zone Ventilation Standard Density Volume Flow Rate
+
[mechSysAirFlow] Zone Mechanical Ventilation Standard Density Volume Flow Rate
+
[earthTubeFlow] Earth Tube Air Flow Volume
[17] airHeatGainRate
=
[surfaceAirGain] Zone Air Heat Balance Surface Convection Rate
+
[systemAirGain] Zone Air Heat Balance System Air Transfer Rate
Output variables on the Read EP Surface Results component:
[1] surfaceIndoorTemp
=
Surface Inside Face Temperature
[2] surfaceOutdoorTemp
=
Surface Outside Face Temperature
[3] surfaceEnergyFlow
=
[opaqueEnergyFlow] Surface Average Face Conduction Heat Transfer Energy
+
[glazEnergyFlow] Surface Window Heat Gain Energy
[4] opaqueEnergyFlow
=
Surface Average Face Conduction Heat Transfer Energy
[5] glazEnergyFlow
=
Surface Window Heat Gain Energy
[6] windowTotalSolarEnergy
=
Surface Window Transmitted Solar Radiation Energy
[7] windowBeamEnergy
=
Surface Window Transmitted Beam Solar Radiation Energy
[8] windowDiffEnergy
=
Surface Window Transmitted Diffuse Solar Radiation Energy
[9] windowTransmissivity
=
Surface Window System Solar Transmittance

Did you get this list by looking at the code in the Honeybee_Read EP Surface Result?
If so its correct.
Grasshope,
For a detailed explanation of outdoor air, see our other discussion:
http://www.grasshopper3d.com/group/ladybug/forum/topic/show?id=2985...
For almost everything else, you correct. There's only a few corrections:
[3] surfaceEnergyFlow
=
[opaqueEnergyFlow] Surface Average Face Conduction Heat Transfer Energy
+
[glazEnergyFlow] Surface Window Heat Gain Energy
-
[glazEnergyFlow] Surface Window Heat Loss Energy
[4] opaqueEnergyFlow
=
Surface Average Face Conduction Heat Transfer Energy
[5] glazEnergyFlow
=
Surface Window Heat Gain Energy
-
Surface Window Heat Loss Energy
Let me know if you have any feedback about the outputs that I thought were useful and how I combine some of them.
