2019-07-16 12:01:31 -0500 marked best answer How to normalize experimental data to a performance curve?

Are there any examples of taking curve fitted experiment data for a DX coil and creating the normalized cooling capacity curve in energyplus? We are trying to do that as part of a research project, but we've clearly done something wrong since the simulation results are way off the experimental data.

Is the curve normalization procedure in any of the energyplus documentation? I was having trouble finding out how to do it.

Also, an example of normalizing a cooling capacity curve from real data would be awesome!

2019-06-19 12:37:12 -0500 marked best answer How to use a Heating Coil to condition Outdoor Air before the Air Mixer?

I want to use a heating coil to heat the outdoor air prior to the outdoor air mixing with the airloop return air in the mixing box. The heating coil would be more efficient since the outdoor air is colder than the mixed outdoor air and airloop return air. However, I can't figure out how to place the heating coil since I only know how to place a heating coil in the airloop, not between the outdoor air node and outdoor air mixer. Any idea on how to do this?

I noticed that TDV is reported in the HTML file in the circled cell, but I would much rather prefer the output to be in a csv file since I already have code to parse those files and collected data from several different simulations.

2019-05-15 10:05:09 -0500 marked best answer Does DaylightingDevice:Shelf causing unenclosed zone output inaccurate results?

Simulating DaylightingDeviceShelf.idf from the Energyplus 9.0 Examples Files, with an Output:Diagnostics,DisplayExtrawarnings object added, creates a warning

* Warning * CalculateZoneVolume: The Zone="DAYLIT ZONE" is not fully enclosed. To be fully enclosed, each edge of a surface must also be an edge on one other surface.

The Warning continues saying the zone volume calculation is done by

* ~~~ * The zone volume was calculated using the floor area times ceiling height method where the floor and ceiling are the same except for the z-coordinates.

Granted, the proper way to specify a light shelf in energyplus is unusual, but it shouldn't create this warning.


What I really care about though is if this will or will not output accurate results. Is there any way to find out?

I know this is very easy in an openstudio measure, but how do I delete an object from the idf file using an energyplus measure?

Also, is there any documentation for writing energyplus measures similar to the openstudio documentation?
