TILU building numbers are identified on Figure 7

As identified on Tables 5.9 and 5.10, STC requirements for glass windows can be reduced to 37 or
below provided that alternative ILU layouts are provided.

Currently, no alternative layouts have been made available to replace the Type 4 double units
(Buildings 94, 97, 101, 104, 105, 107, 108, 116 and 118) located near the Cooroy Connection
Road. If double units are provided by combining two mirrored atternative single units, window STC
values of 37 are likely be achieved for these buildings. However, if alternative designs to those
presented in Figure 9 are proposed, an acoustic assessment of these units would be required to
determine the required construction materials.

Table 5.11 presents potential construction materials suitable for achieving the predicted STC
requirements.
