Separate Zones based on orientation #66

Closed mostaphaRoudsari closed 9 years ago

mostaphaRoudsari commented 9 years ago

Similar to https://github.com/tt-acm/EnergyAnalysisForDynamo/issues/65 but this time for orientations.

I dig it, @mostaphaRoudsari. One question - How is orientation determined for a zone with multiple exterior faces?

mostaphaRoudsari commented 9 years ago

@bhowes-tt if you do the zoning right, you normally shouldn't end up with zones like that but in can still happen in some cases. My approach in Honeybee is to make a separate list for them and let the user decides what they want to do with them > Zones with faces only to orientation a, Zones with faces only to orientation b, zones with faces to both orientation a and b.

Nice. I've certainly seen some zones coming out of Vasari with multiple faces. If we were doing everything inside of a component, would we just choose the largest face?

Or were you thinking of doing this as a cluster or a sample file? We might already be able to do this with the decompoze zone and surface.vector nodes...

I think they happen in Revit and not Vasari. I might be wrong though.

Selecting the biggest face is tricky. It is hard to know what will happen with that specially in case of auto-zoning that the user doesn't have that much control on the zones. I still like the idea of having them in a separate group and let the user decide about them.

I see them as couple of nodes. It should be easy to do so since as you said we have the methods already. I see them as couple of nodes that let you manage the zones > separate by orientation, separate by level, separate by program, etc. I think they will be all pretty useful. I'm not sure when is the right time to add them but I know that they will be useful.

Now that we have decompose zone maybe this should be separate surfaces based on orientation? Then having zones with multiple walls facing different directions will be already addressed! I will check rest of issues including this one on Monday.

With combination of this node and separate by levels users can do interesting facade studies. Here is an example to change glazing constructions. @arkdanielnielsen I guess you will like this for your studies.

PS1: I found 2 bugs in Vasari zoning playing around with these new set of nodes:

  1. Sometimes it generates window between interior walls.
  2. Some of the floors are wrongly assigned as roof.

PS2: DesignScript's vector.AngleBetween doesn't work as expected so I had to write a private method to handle that for now. I've already reported this.
