NC-v4 EQp1:Minimum indoor air quality performance

Mechanically conditioning and natural ventilation

Can a mechanically conditioned space be naturally ventilated? I mean, is this combination allowed by ASHRAE 62.1-2010 and ASHRAE 55-2010?

Hi Gustavo, You shouldn't have a problem here as long as the ventilation meets the requirements of ASHRAE 62.1-2010 Section 6.4 (or is an approved engineered natural ventilation system), and the conditioning systems are able to meet ASHRAE 55. The two standards are really looking at separate performance components. I'd be sure to mark the correct option consistently on the credit forms and provide a section of the systems narrative explaining that the ventilation and conditioning are independent of each other just to make sure it's clear to the reviewer.
