I am doning a new project, and using natural ventilation for one of the rooms. I do read carefully the requirements of IEQP1, but the LEED Guide does not require outdoor air quality test if using natural ventilation. But my colleague thinks that IEQP1 shall meet with the requirements of sections 4 through 7 of ASHRAE 62.1-2007, so outdoor air quality needs to meet with requirements of Table 4-1 (ASHRAE 62.1-2007), and need to take outdoor air quality test. Is Any one clear about whether needs to do outdoor air quality test if using natrual ventilation?

For a naturally ventilated space, you don't have to meet sections 4–7, as discussed in the credit language for IEQp1.

Hi Tristan, Thanks.
After talking with my colleague, for the next project we will ask for local air quality first, If the air quality is poorer than Table 4-1 (ASHRAE 62.1-2007), then suggesting using mechanical ventilation with filters for the comfort and well-being of occpants. If the air quality is good, then it is good way to use natural ventilation.
