Night purge ventilation modelling (scripted profile)
Download PDF Version of Answer
Modelling night purge ventilation is traditionally difficult in VE since it is possible to set the windows to open/air to flow after a certain time of day subject to the space air temperature threshold condition but you then can not easily specify to keep these open through the night after they have opened.
Scripted profiles now offers a route that this can be configured more accurately to how this is operated in reality. See the attached PDF for an example of how this is done and download the script here (unzip to find the txt file as referenced in the PDF instruction).
More detail on Scripted Profiles can be found on the IES Online Help site.
