Building infiltration class

In the calculation of thermal loads Revit MEP offers us the possibility of regulating the flow due to infiltration. This rate with respect is regulated in three steps:

loose = 1,38 m³/h x m² – (0,076 CFM/Sq x ft)

medium = 0,69 m³/h x m² – (0,038 CFM/Sq x ft)

tight = 0,34 m³/h x m² – (0,019 CFM/Sq x ft)

none = 0 m³/h x m² – (0 CFM/Sq x ft)

It is important to remember that the surface on which Revit calculates wall surface is in contact with the outside. Here’s a video showing the comments:
