Re: [EnergyPlus_Support] Simulation errors

[Jose Torre-Bueno <jtorrebueno@xxxxxxx>]

I share Jamie's question.  Obviously having a window or door open is equivalent to having a lot of infiltration but how much?  Is there any way to use energy plus to model this?  Otherwise is there any formula or rule of thumb to convert the size of an opening to an infiltration value for a given volume?  In a benign environment like San Diego simply opening the windows could be a valid strategy to control indoor temperature.

I want to know what will happen if i get a hole in the building like a open windows, i guess the indoor envionment will change depending of the weather conditions.

 

Can i do this?

what would be the purpose of simulating a hole?

solar - use a window
air - use ventilation, mixing or infiltration
other???

EnergyPlus can't model holes in surfaces so you should just comment out or remove that one.

HI!
 
Thanks, I have solved this with your help.
 
I guess the problem was that the small one surface was not abble to discribe like Building Surface, so iIhad to make it like a fenestrion surface.
 
Now i get just one error:
 
** Severe  ** FenestrationSurface:Detailed="VOID SPACE SOUTH" has an opaque surface construction; it should have a window construction.
 
This space that i want to simulate is a void space, is like a windows but this one is open.
 
Would you give me some advice to do this.
 
Thanks

Now go fix this surface - VOID SPACE SOUTH:
** Warning ** Floor Tilt=90.0, much less than expected tilt of 180,
for Surface=VOID SPACE SOUTH, in Zone=ZONE_2

Then look at the 3rd vertex for the surface WALL EAST:
** Severe ** Suspected non-planar surface:"WALL EAST", Max "out of
line"=1.02916E-002 at Vertex # 3

Then go make your door or window a rectangle:
** Severe ** Suspected 4-sided but non-rectangular Window, Door or
GlassDoor:
** ~~~ ** Surface=WINDOWS SOUTH, Diagonal1=39.187, Diagonal2=39.245

Get it now?
