The effect of natural ventilation on relative humidity and the temperature of the zone

[hoorieh]

HI, actually i modeled a very simple zone and used the add glazing component , and i analysed model with and without natural ventilation( window) to see what is the effect of natural ventilation , but unfortunately all data after giving natural ventilation is the same.

Hi,
I guess you have to insert a number for maximum and minimum of indoor/outdoor temperature.
check the link it would be helpful.

How is natural ventilation determined based on min and max values for both indoor and outdoor temperature?

On the Honeybee Set EP Air Flow component the min and max values for both the indoor and outdoor temperature can be specified to determine if natural ventilation through windows (ventilationType=1) will happen. [image] May I ask whether the natural ventilation will only be activated when both conditions are met or either one of them is met? E.g, suppose we set the natural ventilation temperature range for both indoor and outdoor as the following, and for a given hour the indoor temperature of…
