[clarified] about EnergyPlus output variables in HB

A couple of questions about output variable setting in HB:

1. how to specify a particular output variable in HB? (seems the HB_generate_EP_output component have a few, although sufficient, options)

2. how to specify Output:Meter variables, such as Electricity:Building, InteriorLights:Electricity, InteriorEquipment:Electricity, that are used to calculate Plug Loads?

3. What if I want to get the following output variables?

- Zone Total Internal Total Heating Energy/Rate (which is total internal gains)

- Zone Windows Total Heat Gain Energy/Rate and Zone Windows Total Heat Loss Energy/Rate for calculation of net window gains

Thanks!

Hi, Chris,

It seems the ColorZones component can visualize floor-normalized data for otherZoneData in Read EP Results now. However, the 3D Chart component is not responding to the normalized data, and it still shows the non-floor-normalized data for otherZoneData variables.

Does this means the 3D Chart component needs code revision to cope with this kind of scenario?

Thanks!

Grasshoppe,

I forgot to change the name of the data in the Ladybug header when you set the floor normalizing boolean on the result reader to 'True'. Also, I was not actually dividing the values by the floor area inside the component. I have fixed this in the attached file and on the github.

To clarify, there are two places where you can floor-normalize the incoming data mostly for control over whether you want more display options or more speed. If all that you care about is energy intensity, you might as well normalize it on import and, that way, all processing of the data after it will be fast (including coloring of zones). If you want the option to either normalize it later or not, you should import the data as-is (not normalized) and, that way, you keep the option to normalize it later.
