Dear, I have one more question, please. In ASHRAE 62.1-2010 section 6.4.1 there is an explantion about floor area to be ventilated. I didn't understand how calculate the area if there is only the number of distance. For example, to Single Side Opening the floor area to be ventilated would be 2H*(opening width)? Thanks,

This is saying that only the space within a distance of 2H from the openings can be considered to be naturally ventilated. H is the floor to ceiling height. If you have an 8 ft. ceiling, and a wall with openings, only the space within 16' of those openings can be considered ventilated from those openings. Spaces deeper than that would not comply with the natural ventilation.
