Sorry for the late response, @chriss . These are all good questions and I’ll try to answer the ones @mostapha left to me now:
- Adaptive comfort map recipe asks for a DDY file- I’m not sure why this is, as I don’t need to do sizing? Where would I get such a file? I have an EPW but not DDY.
There’s always a sizing calculation that runs with the DDY file at the start of every EnergyPlus simulation. I realize that your particular building might be completely passive, which begs the question of “what is being sized in this calculation?” The answer may very well be “nothing” if all of your Rooms are unconditioned but we still always ask for the DDY file (just in case) since a lot of people run adaptive comfort simulations with models that include heating systems without cooling systems (which still requires that these heating systems by sized with the DDY criteria). Furthermore, there are occasionally some people who still use the Adaptive model for “mixed mode” buildings, which have a hybrid of natural ventilation and active cooling and these cooling systems still need to sized.
- How do I select EN-15251 instead of ASHRAE? I can see the entry box for this, but not clear what the string should be?
Simply change the comfort-parameters to be the following:
You’ll see that there are actually a lot of parameters that you can adjust on the Adaptive comfort model by using the LB Adaptive Comfort Parameters component. If you only specify the standard (as I did above), all of the other parameters will default to aligning with the standard (eg. the
--prevail-method will change to
RunningMean instead of
- How do I change the neutral offset in the Rhino plugin? I can do this in the LB Adaptive Comfort parameters component within Grasshopper.
See above. One of the comfort-parameters that you can change is
--neutral-offset. So, if you want to change the offset to 2C with the EN15251 model, just use the following comfort parameters:
--standard EN-15251 --neutral-offset 2
- How do I set window opening controls in the Rhino plugin (e.g., open by temperature)? I know how to do this in Grasshopper/Honeybee using the HB Ventilation Control component.
To be honest, I haven’t yet tested the Rhino plugin’s features for assigning natural ventilation but @mingbo can answer any questions that arise here and I see that he put a “Controls” section under the “Room Properties” menu that allows you to specify the temperature setpoints for natural ventilation:
To get the natural ventilation in the model to work, you will also have to set the individual Apertures that are operable to have a checked “Is Operable” property under the “Aperture Properties” menu:
It looks like Mingbo also added a whole menu to adjust the various fluid dynamic properties of the Aperture:
