I am not quite sure on the wording regarding natural ventilation and the Europe ACP.
The online Ref.Guide states
"Projects in Europe may use Arbeitsstaettenrichtlinie ASR 5 as a local equivalent to ASHRAE Standard 62.1-2010, natural ventilation procedure."
The requirements regarding natural ventilation call (besides others) to meet the requirements of ASHRAE 62.1 section 4 or a local equivalent. As the ASR 5 is a replacement for section 6.4 in ASHRAE 62.1, does this mean it is replacing section 4 as well?
