FAQs about EQp1 :

A building has fan-assisted ventilation and no mechanical cooling system. Does this qualify as natural ventilation?

What options are available to mechanically ventilated projects outside the U.S. to meet this prerequisite?

NC-v4 EQp1:Minimum indoor air quality performance

jet fans

Table 6.4 of ASHRAE 60.1-2010 states that parking garages that don't have walls that are at least 50% open to the outside shall have mechanical air extraction (exhaust ventilation). Can jet fans be used instead of a ducted extraction system (ductwork)? Best Regards

Hallo Francesco, Is your parking located in a basement or above grade? If your parking is above grade, what is the percentage open to the outside that you could have? One more question: where are you planning to locate the jet fans? If all your walls have no openings and you install jet fans, they will only move the air but they will not introduce outside air. It will not be accepted.

Thank you. And if the project team will develope a simulation (e.g. CFD) that demonstrates that the ventilation rate is higher than the rate requested by Table 6.4 of ASHRAE 60.1-2010?
