6 RECOMMENDATIONS - BUILDING SHELL AND EXTERNAL GLAZING

Impact from shopping center and loading dock areas have been addressed in a previous noise impact assessment
report (ref: 20191414.3/0607A/R7/OB), dated 6 July 2021). The recommendations in this report are based on the
assumption that the Shopping center achieves compliance as per Mediation Judgement. Further, AL has been
advised by Stockwell that loading dock impacts will be treated utilizing Acoustic Barriers and operational controls
measures as listed in the abovementioned report. On that basis, no fagade upgrades to address Noosa Civic
shopping Centre have been adopted.

6.1. GLAZING
The glazing systems should be selected and installed to meet the noise criteria presented in this report.

Minimum requirements are presented to satisfy only the acoustic requirements for the facade and glazing based
on the current assessment methods. Where other requirements for the fagade and glazing are specified elsewhere
in the glazing specification, the glazing shall be selected to meet all requirements and may result in increased
glass thicknesses over those specified in the acoustic specification but shall in no cases fall below the minimum
thicknesses and requirements set out in this specification.

The design of the window mullions, perimeter seals of openable and fixed glazing, and the installation of the
windows/doors in the building openings shall be selected so that the completed system reduces internal noise
levels to at or below the requirements in the abovementioned report and in any case shall meet or exceed the
minimum acceptable glazing requirements nominated below.

Thicker glazing may be required for structural, safety or other purposes. Where required to use thicker glazing
than that scheduled, this will also be acoustically acceptable.

It is recommended that only window systems having test results indicating compliance with the required ratings
obtained in a certified laboratory be used. The submitted glazing system acoustic performance and thickness
deviations from the requirements in this brief are to be approved by the acoustic consultant.

Refer to Appendix A for Glazing types.

The glazing types and markups are satisfactory and applicable on the condition that the acoustic treatments in
section 8 are fully implemented to achieve compliance with the Mediation Judgement No. 765 of 2020

(dated 3 September 2020),
