XCLUSIONS
Buildings/premises which are inherently noisy and unaffected by noise
from adjacent premises/spaces.
O
BJECTIVE
Improve the noise isolation of normally occupied premises/rooms to
reduce impact of unwanted noise.

None.

REDIT REQUIREMENT
1 credit for demonstrating airborne and impact noise isolation between
rooms, spaces and premises meets the prescribed criteria.
For residential developments only,
1 BONUS credit for demonstrating impact noise isolation between floors
meets the prescribed criteria.
Based on the nature of the building, relaxation should be allowed in
considering the acceptance of this credit. The applicant should provide
full submission of the design and calculation to justify the relaxation.
A
SSESSMENT
As there are number of ways to quantify or classify noise isolation
(insulation) in buildings, the exact performance criteria used to define
both airborne noise isolation and impact noise isolation shall be stated by
the Client. However, for the purposes of assessment account should be
taken of the criteria given below. Where alternative criteria is used the
Client shall provide evidence as to the suitability of the alternative, e.g.
by making reference to authoritative guidance. Likewise, where criteria
appropriate to the type and use of premises/spaces is not stated herein,
the Client shall provide evidence as to the suitability of the criteria
adopted.
Compliance shall be demonstrated by measurement or by detailed
calculations, or both, depending on the Client’s preference.
Measurements shall follow the protocols given in the referenced
standards. Calculations should be done with reference to appropriate
standards.
The Client shall submit details in the form of a report prepared by a
suitably qualified person providing a schedule of the premises and
spaces in the building, the noise isolation criteria adopted, relevant
structural details as they impact on noise isolation, the rooms/premises
subject to field tests or for which detailed calculations have been made,
underlying assumptions, and the results of tests or calculations
demonstrating compliance with the criteria (expressed in parameters that
are consistent with the test and/or calculation methods).
Where it can be demonstrated that airborne noise isolation, as measured
or calculated for the most susceptible spaces/rooms/premises, meets
appropriate performance criteria the credit shall be awarded.
For residential development, where it can demonstrate that impact noise
isolation (insulation) meet appropriate performance criteria in the most
susceptible spaces/ rooms/premises, the BONUS credit shall be
awarded.
