XCLUSIONS
Residential and similar buildings without central air conditioning.
O
BJECTIVE
Ensure that a minimum quality and quantity of outdoor air is supplied to
spaces in the project in order to support the well-being and comfort of
occupants.
R
EQUIREMENT
Demonstrate that the project is in compliance with the minimum
requirements of ASHRAE 62.1-2007 [1] in respect of Outdoor Air Quality;
and Minimum Ventilation Rate.
A
SSESSMENT
The Client shall provide evidence in the form of a report prepared by a
suitably qualified person detailing the outdoor ventilation performance.
The report shall include:
1. Confirmation that the outdoor air pollutants Carbon monoxide (CO),
Nitrogen dioxide (NO
2
), Ozone (O
3
) and Respirable Suspended
Particulates (RSP) conform to the IAQ Certification Scheme Good
Air Quality level.
2. Completion of Table H-2 of ASHRAE Standard 62.1-2007
demonstrating compliance with the minimum ventilation rate(s)
provided.
B
ACKGROUND
The purpose of this prerequisite is to provide the minimum outdoor air
ventilation for the control of odours, that is, the supply, distribution and
control of ventilation to maintain carbon dioxide (CO
2
) levels within the
design targets in normally occupied spaces, and the control of indoor
pollutants such as TVOC’s, formaldehyde, etc.
The assessment for building follows requirements of ASHRAE
62.1:2007. The standard includes significant requirements other than
outdoor air rates, such as requirements for equipment to reduce the
potential for microbial growth, air cleaning requirements, and start-up
and commissioning requirements. All of these requirements must be met
to comply with this prerequisite.
