6.2.3 Requirements
This section specifies requirements for indoor environmental quality includ-
ing indoor air quality, environmental tobacco smoke control, outdoor air
delivery monitoring, thermal comfort, building entrances, acoustic control,
day lighting and low-emitting materials. A typical building should comply
with the indoor air quality requirements as outlined in international codes
and standards (ASHRAE Standard 62.1) and ISO 16818.
6.2.4 Minimum Ventilation Rates
1. The ventilation rate procedure outlined in ASHRAE Standard 62.1
is recommended as a tool to design each mechanical ventilation
system in the building.
2. The zone-level design outdoor airflow rates in all occupiable spaces
shall be greater than or equal to the airflow calculated using the ven-
tilation rate procedure.
6.2.5 Outdoor Air Delivery Monitoring
6.2.5.1 Spaces Ventilated by Mechanical Systems
For variable air volume supply systems, a permanently mounted, direct
total outdoor airflow measurement device shall be provided that is capable
