Matias,
  Modeling natural ventilation isn't a very easy task - you need to link 
the building thermal model in TRNSYS with an airflow model using either 
COMIS 3.2, CONTAM (Type97) or TRNFlow. Each of those represents an 
airflow model of the building that determines the amount of ambient air 
that will flow into the building due to wind pressure and buoyancy 
(temperature and height difference) effects. You would presumably also 
have to write a model of a set of windows that open and close between 
your 5 and 21 C temperature set points. You might begin by looking at 
Type97's mathematical description and at the CONTAM example that is 
provided with TRNSYS.
Kind regards,
 David
