Dear all, We have a 10-storey office building located in Germany with 1 AHU for each floor. Each AHU serves different zones (office, storage, kitchen etc.). As all AHUs should be included, does it mean that we should submit one 62MZCalc file for each? Or maybe add worksheets in one single file? I am looking forward for your answer. Thanks!

Did you think of showing IEQp1 compliance based on EN 13779 and EN 15251? This may be an easier option.

Jens, thanks for your answer. The fact is that we already submitted this prerequisite to USGBC using one single 62MZCalc file and we got this answer: "It appears that the VRP calculations have been performed for a single multi-zone recirculating system. Note that the VRP calculations must be provided for each mechanical ventilation system separately."
