[TRNSYS-users] Impact of opening windows on interior comfort

[David BRADLEY via TRNSYS-users]

Ismail,

   Thermally speaking, opening a window causes more air flow to come 
into the building. It is quite easy to increase the infiltration into 
the building based on a schedule of 2 hours per day. The problem is to 
know how much air comes into the building as a result of opening a 
window and that is where TRNFLOW (or CONTAM/Type97) are useful. If you 
are trying to avoid using TRNFLOW because it is an add-on then you can 
use Type97 in the standard library (and CONTAM, a freely available 
software tool from NIST). If you are trying to avoid using TRNFLOW 
because of the amount of extra information that you need to enter then I 
am not aware of any simple alternatives in Trnsys17 that amount to much 
more than making a guess as to the air flow rate that comes in through 
the windows.

kind regards,

  David
