Minimum IAQ Performance

Comply with minimu requirements of ASHRAE 62.1
Prereq Intent
Establish minimum indoor air quality performance to enhance indoor air quality in the OCCUPANT SPACE, thus contributing to the comfort and wellbeing of the occupants.
Meet the minimum requirements of the voluntary consensus standard _________ Ventilation for Acceptable Indoor Air Qaulity Mechanical ventilation systems shall perform according to the __________.

ASHRAE 62.1-2004

Ventilation Rate Procedure

___________ must comply with ASHRAE 62.1-2004 Section 5.1

Naturally ventilated
Modify or maintain existing building outside air ventilation distribution system to supply at least the outdoor air ventilation rate required by____________.
ASHRAE 62.1-2004
If the project cannot meet the outside air requirements of ASHRAE 62.1-2004, it must document the space and system constraints that make it not possible, and complete and engineering assessment of the system’s maximum cu.ft. per minute capablity toward meeting the requiremetns of ASHRAE 62.1-2004 and achieve those levels with and absolute minimum of :
10 cfm per person.
For existing buildings that cannot meet ASHRAE 62.1-2004 the enigneer must:
certify a letter that they have in hand and will deliver to the client, photgraphs/specs or cut-sheets of mechanical equipment as built Mechanical plans, or single line drawings as0builts of the space constrained aspects in system.
