Inquiry

Can projects use the natural ventilation prescriptive dimensional requirements written in 62.1-2010, instead of those in ASHRAE 62.1-2007? This would allow some spaces to comply with the requirements where they may otherwise not if 62.1-2007 is applied. If so, are we required to comply with the standard as a whole? Applying the standard as whole would have serious implications for new construction or existing projects attempting to comply with the Natural Ventilation Procedure because in some instances mechanical ventilation systems would have to be installed to meet the prerequisite.
