NC-v4 EQp1:Minimum indoor air quality performance

Zone Air Distribution Effectiveness

In the office the air (cold in summer, warm in winter) is both wall supplied and ceiling supplied. The air is exhausted from the WCs. From the offices the air passes through the doors and through a corridor. Which value is appropriate for the Zone Air Distribution Effectiveness? Best Regards

Buongiorno! Your worst case scenario is heating mode with warm air supplied from the ceiling. Therefore, your Ez will be 0.8.

Hi Gustavo, in addition to the question of R2M Solution Srl I was wondering if it is appropriate to use Ez = 1,0 if the air is ceiling supplied (heating mode) and will be exhausted / passes through undercuts in the doors to the exhaust AHU in the WCs. My understanding is that the mode 'ceiling supply of warm air and floor return' can be used for this case? Thank you!
