<p>Thank you! I will look at it as soon as I can! My problem, however, was related to the possibility to chose how to calculate Comfort, in Energy Plus idf editor I can select CEN Adaptive Comfort and along with it I can add specific schedules and Internal Gain settings that I couldn't add in Honeybee... so the problem of the sensible heat fraction was only part of the problem ...</p>

<p>Hi Filippo,</p>
<p></p>
<p>I´ve just ended up editing the RunEP simulation component. The line 1046 let´s you define the Sensible heat fraction that is being written in the .idf.</p>
<p>I hope this helps</p>

<p>Hi Mostapha and thank you for your reply,</p>
<p>Yes I need to apply the change globally.</p>
<p>I attach the two different example idf file, the gh and the word file with the comparison of the two files.</p>
<p></p>
<p>I would like to add inside Honeybee the possibility to calculate CEN Adaptive Comfort. At the moment with Honeybee I can only generate an "incomplete" file and then apply the correction through the idf editor. This, for example, makes it impossible to use the discomfort hours…</p>

<p></p>
<p>I would like to add inside Honeybee the possibility to calculate CEN Adaptive Comfort. At the moment with Honeybee I can only generate an "incomplete" file and then apply the correction through the idf editor. This, for example, makes it impossible to use the discomfort hours as a fitness function for an optimisation inside Grasshopper.</p>
<p>What I need:<br/>I need to modify the internal gains section and to add some schedules and output variables.</p>
<p>What's the problem:</p>
<p>Whenever i need additional strings that are not already written by Honeybee I can add them in the Honeybee Run Energy Simulation (for example i need the adaptive comfort CEN outputs and I can have them added using a panel).</p>
<p>For the additional schedules I think it's a bit more complicated because I don't know if I can add more input into the Honeybee Set Energy Plus Zone Schedules to plug in some more Schedules (their name are WorkEFF_SCH - work efficiency, ClothingINS_SCH - clothing insulation and AirVELOCITY_SCH - air velocity), maybe I can add the additional schedules inside the additional strings input along with the additional output variables?</p>
<p>Third and most complicated issue, I need to insert some values mainly inside people internal gain (but also into lights and electric equipment) but I don't know how to do it, if I try to add another "people" internal gain from the additional strings as I have done for the output variables I end up having two people internal gain.</p>
<p>This problem maybe could be resolved by adding the possiblity to block the automatic creation of the internal gains, so if I can stop Honeybee from writing them maybe I can then add them through the additional strings option...</p>
<p></p>
<p>thank you very much!!</p>

<p>Hi Filippo,</p>
<p>Is it something that you need to change globally for all the zones? Can you apply all the changes that you need to an idf file generated by honeybee for a single zone and then send me both the original and the updated idf files?</p>

<p>Hi Mostapha,</p>
<p>I'm back at trying to run an E+ simulation with Honeybee using the adaptive comfort for European coutries (CEN) and I need to customize the people internal gain in order to do this. Any upgrade on the issue? I need to add some additional strings inside the perople internal gain:</p>

<p>Thank you very much Mostapha,<br></br>actually we think that only if we can fully customize the internal gain part we will be able to use honeybee and ladybug to perform professional and research simulation at ease (even in Europe where we have different regulation for example regarding the comfort where the ASHRAE standard is replaced by CEN).</p>

<p>It would be great if honeybee could allow us to do one of the two following options:</p>
<p><br/>1) insert our personal internal gains strings through the additional strings command, with an ovverride on the in-built internal gains of the "runEnergySimulation" command;<br/>2) create a specific command for internal gains (as you have already done for other commands) where various strings can be added to the energy plus file along with their schedules.</p>
<p>this way it would be possible to use the software to model a specific occupancy situation with its internal gains.</p> Hi Filippo,

<p>Hi Filippo,</p>
<p></p>
<p>Do you still need help with this or is it already solved?</p>
<p></p>
<p>When I was putting default values for people inside the component I had the wrong assumption that nobody would ever need to change this one and you and <span>Letizia proofed me wrong. I will be happy to help you get a clean solution for setting up the internal loads. Let me know how can I help.</span></p>
