Hi everyone!

I'm having a trouble with calculations for this credit. I don't understand whether the outdoor air volume of 4 267 140 l/m2 (14,000 ft3/ft2) is needed to be delivered for the whole project's area or do I need to count how much air is need to be supplied per each single room taking into account this space ventilation system capacity and area? On one hand, the Reference Guide (Equation 4) tells to use Air handler capacity which would suggest that the equation is prepared for an entire building, but Examples 1-4 make me wonder if that's true since it divides a projects into 3 different spaces. The way of calculating really affects the length of flush out needed.

Thank you in advance,

Kasia
