Alternative:
B. Measurement Approach
The objective of sampling is to ensure that the interior spaces will not
suffer undue contamination from indoor sources or infiltration from
outdoor sources. Where it can be demonstrated that identified
pollutants (B1 to B5 as stated below) are complied with the Good
Class requirement prescribed in the IAQ Certification Scheme,
credit(s) shall be achieved.
B1. Total Volatile Organic Compounds (TVOCs)
B2. Formaldehyde (HCHO)
B3. Products of Combustion:
i) Carbon Monoxide (CO)
ii) Nitrogen Dioxide (NO
2
)
B4. Respirable Suspended Particulate (RSP, PM
10
)
B5. Ozone
Measurements shall take place during normally occupied period.
Documentation
Credit(s) shall be achieved when the Applicant provides the
documentation stated below, to demonstrate compliance:
A. Design Approach
i.

emissions rates for materials in classes A2 and A4, the
permitted emissions limit for each of the materials as
specified in referenced documents, and details of the source
data (e.g. manufacturer data sheets);
ii.
Specifications for the materials/components as they appear in
construction documents;
iii.
Confirmation of compliance with the relevant
standard/emissions criteria.
B. Measurement Approach
i.
The method statement of IAQ measurement;
ii.
Measurement report issued by an HKAS accredited IAQ
Certificate Issuing Body with measurement methodology,
