REDIT REQUIREMENT
A. Specifications
For each of the materials categories (A1 to A5), one credit is achieved
when compliance is demonstrated through submission of the requisite
documentation.
Alternative:
B. Measurement
For each of the categories of contaminants (B1 to B5) one credit is
achieved if measured concentrations obtained through appropriate
measurements comply with the Good Class requirements in the IAQ
Certification Scheme
[1].
A
SSESSMENT
Criteria
Two alternative methods are available to demonstrate compliance: A.
by design, whereby indoor contaminant sources are reduced through
selection of materials, or B. through measurement of contaminants
upon completion of the project.
A. Design Approach
A1. Adhesives and Sealants
Where adhesives, sealants and sealant primers are used in the
project interiors, the VOC content limits should less than the
maximum limit given in Annex 6 of “A Guide to the Air Pollution
Control (Volatile Organic Compounds) Regulation” issued by
Environmental Protection Department [
2].
A2. Paints, Coatings and Finishes
Where paints, coatings and finishes are used in the project interiors,
the VOC content limits should less than 50g per litre.
A3. Wood and Laminates
i.
Composite wood and fibre products shall not contain any
added urea - formaldehyde resins;
ii.
Adhesives used to fabricate assemblies shall not contain any
added urea - formaldehyde.
