According to this section, a local survey is needed to document the local air quality. But even the GBCI refers to the ventilation rate procedure when we ask for clarification, and the form/uploads do not require a outside air quality measurement. Does anyone know why section 4 is mentioned in the prerequisite if the rate procedure is required?

Gerrit.Jan, there is no upload for the ASHRAE-compliance, but in the form of IEQp1 the "Ventilations Systems Designer" needs to sign this compliance with his initials.
We are currently discussing this issue for- and backwards: Does anyone have experiences with section 4 "Outdoor Air Quality" in LEED projects outside the US? If the air analyses and classifications required by ASHRAE are not available in a country - would that exclude the project from certification?

4.1 Requires a site classification: "attainment" or "non-attainment".
The standard does not require any classification for confomance, it simply requires it to be classified. Areas with no EPA compliance status designation shall be considered "attainment" areas. This must surely count for all international areas.
4.2 Requires a general visual and smell observation site survey during normal building occupation times.
4.3 Requires a short report on 4.2 and 4.1.
This section should in no way hamper certification. It should only clarify things like that it was observed in the planning not to go pointing the outdoor air grill in the direction of car exhaust gas, etc.

We found out that air quality measurements are available on the internet, not specific for our location, but at a representative location nearby. For our project(s) in Amsterdam, it appears that all levels are fine. This is a good starting point, no additional filter types are needed in the existing ventilation system. A visual and smell survey is expected to be performed within a few days by our engineers, but we do not expect problems by that.

Jean:
ASHRAE 62.1-2007 ch. 4.1 says
"IN THE UNITED STATES, areas with no EPA compliance status designation shall be considered "attainment" areas ".
To me this sounds like "outside the US the attainment for each pollutant shown in Table 4-1 has to be determined (e.g. by measurement)."
Since the CI-Reference Guide IEQp1 ch. 4 recommends to evaluate the planned location of the project PRIOR TO leasing or acquistion, this i.m.o. can lead to a failure of the prerequisite!
Any opinions on that?

My interpretation of a recommendation is that it is not a requirement. The mail goal is of this part of the prerequisite to provide a descent level of indoor air quality to the building occupants. The prescribed survey of the actual air quality is a good method to detemermine adjustments if needed, and to confirm that the AHU's are equiped with right components. The reference to the ASHRAE standards is always focused on the US situation, and abroad situations should always try to find a workaround (as good as possible). Does anyone have experience in using a alternative compliance path or the "special circumstances" option on this prerequisite?
