I am curious about the function of the "Outdoor Air Flow Rate Fraction Schedule" under "DesignSpecification:OutdoorAir" of space type. (I use OS 1.13)
The inputoutput reference file shows that this field will defines how outdoor air requirements change over time. However, I test a few models with different schedules but results didn't show any difference. What is the function of "Outdoor Air Flow Rate Fraction Schedule"? What output will it affect?
