Dear all,

We are working on a Project of a warehouse building, using only natural ventilation to meet the minimum indoor air quality prerequisite. Due to the extension of the building and the exhaust ventilation being in the roof, it is not possible to meet the requirements of the section 4 of ASHRAE Standard 62.1-2010, therefore, we are meeting the requirements of airflow rate (Table 6-1, ASHRAE 62.1-2010) by computational simulation.

That said, we are seeking to meet the prerequisite by an engineered natural ventilation system approved by authority with jurisdiction, with USGBC serving as this authority. Then, we would like to know if someone has done it before and what is the procedure. The documents proving the compliance of ASHRAE’s minimum airflow rate are sent directly in the project submission? If it is sent to USGBC before the submission, how is that made?

Thanks in advance.
