Closure methods used to seal metal ductwork shall be put in in accordance with the manufacturer's installation directions.

Thus, the ventilation rates in pure air flow rely upon the size and distribution of the openings in the constructing envelope and on the magnitude of the driving forces , which are the stack effect and wind pressure. The stack effect is determined by the peak of the building and the temperature difference between indoor and outdoor air. Wind pressure is determined by wind speed and course. If the indoor surroundings is conditioned, the power used to warmth, cool, humidify or dehumidify the air flow air may be significant.
