Re: [TRNSYS-users] Cp calculation

[David Bradley <bradley@tess-inc.com>]

Stephan,
  Our lives would be so much easier if architects would just make
square buildings, wouldn't they? :-) When faced with similar problems, I
used TNO's CpGenerator but broke the building up into rectangular
sections, treating the other sections as obstructions. I think you will
have to do your building in five sections as follows (in each top view,
the modeled rectangular section is in red and everything in black is
treated as an obstruction.

Dear All,
 
I am looking for a programm to calculate Cp-values on a building facade. I know of CP-CALC+ and TNO?s CP-gen, but both only consider rectangular shaped buildings. The building I have looks like this in cross section:
 
Cross section:
 
level
  5     xx
  4     xx
  3     xx
  2     xx    xx
  1     xx    xx
  0     xxxxxxxx
 
Top view:

Level 0 is a carparking, levels 1-5 are dwellings.
I want to estimate cp-values at the roof of level 0 as some ventilation openings might be situated here. I am interessed in the flow to/from these openings.
 
Does anyone have any suggestions?
 
Met vriendelijke groeten,
