Grasshopper

algorithmic modeling for Rhino

Hello,

Actually there are two questions:

1.

I'm trying to set up a file to do a simple HVAC simulation. When I only have one Brep as a test, the file runs fine. But once I increased the number of Breps, problems emerge:

- createHBZones component stopped making closed volumes

- or, if I bypass that and directly use the HB zones created in 'Glazing based on ratio', the setEPNatVent gave me an Error saying '1. Solution exception:Cannot create instances of Brep because it has no public constructors'

Did I do something wrong? I don't know if it's a problem with the way I set up the zones or not.

2.

The second question is not about EPNatVent but the difference between 'Export to Open Studio' and 'Run Energy Simulation'? I have both in my file but somehow Export to Open Studio won't run while the other one does. Any particular reason why they operate differently? They seem to run with the same inputs...?

I do know that Open Studio by default does not run CSV schedules, but I imported the new Github, so that should be fine. Also, Run Energy Simulation cannot simulate HVAC other than Ideal Air Load. But I'm trying to run it with Chilled beams, so I'm hoping Open Studio would work.

Thanks in advance!!

Katherine
