According to ASHRAE 62.1 - 2010 User's Manual, example 6-AF, the requirement associated with controls that guarantee that the openeings remain open during occupancy can be met with an administrative policy. Does this mean that the provision of ASHRAE 62.1 -2010 (section 6.4 exception b.1), "controls that prevent the openings from being closed during periods of expected occupancy", can be complied with a mandatory administrative procedure / policy ?
