algorithmic modeling for Rhino

integrating integrated daylight and energy sim with Nat vent, light shelf, etc.

I am working with the integrated daylight and energy simulation plus light shelf and Nat Vent, and Galapagos. I have some technical questions, mostly about how the HBcomponents work. I find combining the daylighting and energy sim with Nat Vent create many complex questions.
Daylighting :
1. Adding shading to energy AND daylight simulation: Can I add HBconext to Honeybee_run daylight simulation HBobject input ?
Looking at the results it seems like daylight simulation doesn't recognize HBcontext, or maybe the difference is minute. Am I doing this correctly? Is there a possible error due to redundancy ? (meaning I am introducing the HBcontext twice, one time to the Honeybee_run daylight simulation AND energy simulation)
2. One of the component, Honeybee_Read annual result 1 keeps failing and says that ''1. Solution exception:index out of range: 0." I read here input needs to be internalize data but maybe there is a better solution?
Shading :
I want to study life cycle perspective of 
A) Optimal ratio of fixed vs dynamic louvers for economic implementation, 
B) Assess whether it makes more sense for the dynamic louvers to functions as light shelvs or the fixed ones for economic reasons 
C) Simulate dynamic/fixed hybrid louver system schedule, and show it in a manner similiar to lighting schedule.
For this I would need to simulate the effect of dynamic and-or fixed shades in reducing annual lighting cost while reducing cumulative heat gain.
3_How to introduce Dynamic shading schedule for custom shades? Is this done with EPtranschedule input of the HB EP context component? I would like to keep the louvers branched so that it is possible to assign different modes i.e. fixed or dynamic
Light Shelf: 
4_Is the lighting schedule effected by light shelves introduced in the annual daylighting simulation?
5_Does energy simulation take account of additional heat gain from light shelvs ?
6_When I use Honeybee_createHBSrfs with Honeybee_radiance Mirror material, it crashes rhino. The geometry input is not branched. Any report similar crashes?
Nat Vent:
I want to design to combine passivhaus principles with Natural ventilation.
My goal to simulate the energy performance of passivhaus house like building system with Bouyancy driven Nat Vent design which maximizing the percentage of the year Nat Vent takes care of ventilation and cooling, and in cloud days heat exchanger with fans kicks in.
using a trombe roof that heats air and using a vertical shaft that recirculate air, want to minimize the use of fans, Ducts, Heating etc. and I want to use the HB Set_Air flow component to evaluate such system if I can.
while I have heard that bouncy driven system may only be reserved for tall buildings, I still would to simulate the effectiveness for mid rizes and podium- types. I am skeptical whether there will be enough pressure difference for effective ventilation of 1.5ms so I would like to test.
 
How to set up models to evaluate bouyancy driven ventilation : 
7 About HB Set_Air Flow, with Natural ventilation, If I use the HB Set_air the honeyzone output is null. I am not sure why, no error messages.
8_ When using the HB Set Air component to include Nat Vent with bouyancy,
does the result of reduced temperature to take effect into the cooling/equipment/ventilation schedule of the Honeybee_set Energy plus zone schedules?
Additionally I want to incorporate Nat vent analysis with the light shelf, since both would effect indoor temperature. 
A wish list: as if it were all this has been not.
9_I wish there is something like a deconstruct honeybee zone component that basically breaks down all the options (mechanically ventilated or not) that is associated with the honeybee zones so that it is easy to document all the properties in text.
