Re: [TRNSYS-users] several outdoor temperatures

["Diego A. Arias" <daarias@wisc.edu>]

The building model only allows for defining one outdoor temperature 
(ambient temperature).  This information is used by Type56 to set the 
temperature of the out walls and the temperature of the infiltration 
air.  Regarding the out wall temperature, you cannot set different 
temperatures.  But, you might find useful that Type56 uses two methods 
to take into account the air that is entering the building: ventilation 
and infiltration.  Infiltration is defined as the ambient air entering 
the zones, and Ventilation is the air entering from heating or cooling 
equipment.  You can set different ventilation schemes into the zones, 
and therefore you can specify their corresponding temperature and 
humidity.  If you do this, you will be able to set different airflow 
conditions, but you won't have the actual conduction through the walls.
Thank you very much for your input.  We have added your comments for a 
future enhancement of the building model.
Best regards,

Diego
