Hi,
Our project is located in Asia with a tropical climate. When we submitted our calculations for IEQp1: Minimum Indoor Air Quality Performance; the assessor came back with the following comment:
It appears that the calculations may not have been performed for the worst-case conditions. Generally, worst-case conditions are during heating mode;Provide revised Ventilation Rate Procedure calculations for zone air distribution effectiveness, Ez, of 0.8 (for an overhead distribution system in heating mode) and when the VAV system is at minimum flow.
My question is why we need to do calculations during heating mode as we do not use heating during any part of the year.
