The atrium has a revolving door, which revolves once every 30 minutes, and the swing door opens for 30 minutes every 8 hours for shift change. My question is how to simulate the revolving door and swing door in eQuest? I noticed that ASHRAE 90.1-2010 mentioned the infiltration from these two types of doors is 1.0 cfm/ft2 tested at a pressure of at least 1.57 pounds per square foot (psf), but I do not quite understand what this means and how to use this number in my model. If any one has an idea, please give the comments.
