ADOPTED NOISE LIMITS

Based on the above and the fact that all of the closest residential are apartment buildings, the noise
limits which have been adopted in this report, for immediately outside a residential apartment, are as
described by Condition 81 of the Noosa Council approval for steady state noise and, for time varying
noise sources, as follows:

Steady State Noise Source

•    daytime (0700 to 1900 hours):                          45 dB(A) LAeq,adj,T;
•    evening (1900 to 2200 hours):                          39 dB(A) LAe,adj,T;
•    night-time (2200 hours to midnight):                   36 dB(A) LAeq,adj,T.

Time Varying Noise Source

•    daytime (0700 to 1800 hours):                          45 + 5 = 50 dB(A) LAeq,adj,T;
•    evening (1800m to 2200 hours):                         39 + 5 = 44 dB(A) LAe,adj,T;
•    night-time (2200 hours to midnight):                   36 + 5 = 41 dB(A) LAeq,adj,T.


PLANT AND EQUIPMENT

For the Facilities Building all of the plant and equipment is located on the roof plant deck. On the
western side of the plant deck a Sonic Series 100 acoustic louvre has been installed with an insertion
loss of:
     • 63 Hz:             -
     • 125 Hz:            4 dB;
     • 250 Hz:            5 dB;
     • 500 Hz:            8 dB;
     • 1000 Hz:           12 dB;
     • 2000 Hz:           16 dB;
     • 4000 Hz:           15 dB.

All sides of the roof top plant deck has differing height masonry nib walls, ranging from 800 mm to 1600
mm high.

The plant and equipment located on the plant deck is as follows:

     •    kitchen exhaust fan;
     •    Daikin RXYQ8AYM;
     •    Daikin RXYQ16AYM (gymnasium);
     •    Daikin RXYMQ4AV4A (two of);
     •    Glacier GC 301-B-2.7 (two of);
     •    MINT HUCE22-1M;
     •    MINT HUCE-1L.

In addition to the above there will be an additional four air-conditioning units located on the roof of the
pizza bar (near the pizza oven), which service the dining area when it is enclosed. These air-
conditioning units are Daikin model number RZAV140CV1 with a sound power level of 75 dB(A) LWA
each for normal mode and 71 dB(A) LWA for the night quiet mode. The separation distance of these four
air-conditioning units to the closest residential – Block 3 – and the quieter night-time mode will ensure
that the noise of these additional air-conditioning units, in conjunction with all other plant and equipment,
will comply with the daytime, evening and night-time noise limits, for their associated hours of operation
(up to midnight).
