ASHRAE specifies that the Ventilation Rate Procedure or the IAQ Procedure can be used to ensure that mechanical ventilation systems meet ventilation requirements in ASHRAE 62.1 (Section 6.1). The intent of the Minimum Indoor Air Quality Performance prerequisite is to meet ASHRAE 62.1. However, LEED specifies that the prescriptive Ventilation Rate Procedure must be used to show prerequisite compliance. Is the performance-based IAQ Precedure considered an acceptable compliance path to meet IEQ Prerequisite 1?
