The designated use of the space may alter or modify the general occupancy requirements but the requirements are there. The code does however provide some exceptions related to the openness of the mezzanine provided certain conditions. forth in the International Mechanical Code. I wrote a multi-part explanation of the Manual D process last year, explaining how the available static pressure, total effective length, and friction rate determine the duct sizes you need to use to get the right air flow. Such mezzanines do not need to contribute to either the building area or number of stories as regulated by Section 503.1, when determining how big or tall a building can be. (speaking from personal experience).

Equipment platforms in buildings shall not be considered as a portion of the floor below. ), The good news for whole-house ventilation afficionados is that the airtightness requirements in the 2015 and 2018 IECC eliminate that sweet spot. The maximum air leakage allowed in IECC climate zones 1 and 2 is 5 ACH50 and in climate zones 3 through 8 is 3 ACH50. But there are a couple of other critical steps that have to follow.
