Atmospheric noise limits for plant (normal operations):

Overall Plant Criteria

The cumulative atmospheric noise levels(i) from the development, should not exceed thebackground noise level(i) at the nearest noise sensitive premises(i) by greater than 5 dB,during the operating period of the plant

If the cumulative plant noise level includes tonal or intermittent characteristics which drawspecific attention to itself, the plant noise level should not exceed the background noiselevel

Individual Plant Criteria

No single item of plant should exceed 5 dBA above the background noise level at 5metres from an outlet/inlet where directly adjacent to normal walkways, open public orstaff areas, or pedestrian areas

Individual or cumulative plant noise should not result in noise break-back into thisdevelopment or any other commercial which exceeds the internal noise criteria (proposedahead), e.g via windows, roof, floor or other indirect paths

The above criteria can be superseded by local authority by-laws, development/planningconstraints, national policy regulation or guidance

For standby/ emergency use equipment (generators / UPS etc):

The cumulative atmospheric noise levels(i) from this plant, during testing or inemergency, should not exceed the pre-existing background noise levelat the nearestnoise sensitive premises(iii) by greater than 15 dBA (if commercial/industrial) and 10 dBA(if residential), during the operating period of the plant Further it should not exceed noiselevel at the adjacent noise sensitive boundary by more than 65 dBA (if commercialIndustrial), and 55 dBA/45dBA (for residential day/night respectively)

Such plant should cumulatively not result in noise break-back into the development which

The above criteria can be superseded by local authority by-laws, development/planningconstraints, national policy regulation or guidance, or alternative criteria agreed withrelevant parties.

Internal noise limits

The following maximum noise levelsi are proposed for the various areas within thedevelopment

Private office space, meeting rooms,

Emergency operating generators / fan systems See (vii)

Services which pass across ceiling spaces, through internal walls and along risers should

be considered in terms of their ability to degrade internal sound isolation performanceneeds, and methods of closure around or within services would need to be considered ineach specific instance

Proposed vibration isolation/structure-borne noise protection.

As a principle, major plant and associated equipment should be installed with vibrationisolation selected so as to provide at least 95% isolation efficiency between the plant andadjacent structure All such plant should also include a noise stop pad as separation fromthe structure in order to attenuate structure-borne noise

All isolation systems should to be considered in terms of the need to accommodatesuitable seismic restraints / bracing etc Such systems should be in line with all local by-laws and codes, standards for the area including compliance with Australian StandardAS1170.4 earthquake loads Open type mounts are preferred, but may not be possible ifseismic requirements need to be accommodated All restraints that are included shouldnot restrict the isolation efficiency of the system supported Care needs to be taken toensure that any super-structure, e.g for anchor embedment, is in place to accommodatethese needs

Standby generators should include carefully selected isolators provided by the supplierthemselves or sub-contractor: air spring mounts would be typically anticipated

It would be expected that:

Large pumps or pump sets would be located on inertia bases at least 1.5 x the weight ofthe pump/s The bases would be supported on open type spring mounts offering at least

25 mm static deflection, and including a noise stop pad

Large fans would include open type spring mounts offering 25 mm static deflection Theunit as a whole would be located on 10-15 mm rubber/neoprene pads or strips, offering1-2 mm static deflection.

Large pipework within plant rooms or across roofs above staff areas, such as fromstandby generators, chilled water pumps etc should include vibration isolation and anoise stops as appropriate, i.e vibration isolation hangers, with noise stops, to soffitsupported pipework; and resilient brackets around roof supported pipes Large pipeworkshould be vibration isolated for at least 50 pipe diameters, within plant rooms or over thesensitive area for which they pass , whichever is the longer

Air cooled chillers and cooling towers would be isolated from the building structureappropriate to their type and specific location They would at least need to be located on

at least neoprene/rubber pads offering 2-3 mm static deflection

Other fans and system should include proprietary vibration/noise isolation as applicable.General Information

All fan systems should include sufficient space for either in-line attenuation ( e.g at least1.5 m long) and/or lined ductwork for at least 5-10 metres

Space should be included within the superstructure design to accommodate vibrationisolation supports for plant

All noise and vibration control measures, attenuator selections etc should be provided tothe acoustic consultant for comment

All local codes/criteria which differs from that given above, should be confirmed to theacoustic consultant or appropriate party

All noise and vibration control measures, attenuator selections etc should be provided tothe acoustic consultant for comment

All local codes/criteria which differs from that given above, should be confirmed to theacoustic consultant or appropriate party

All local codes/criteria which differs from that given above, should be confirmed to theacoustic consultant or appropriate party

i.Cumulative noise level should be in terms of the LAeq noise parameter (A-weighted equivalent continuous noise level) measured over sample periods of not less than 15 minutes.

ii.The pre-existing background noise level should be in terms of the LA90 (A-weighted noise level exceeded for 90% of the period) The LA90 parameter should be determined from a noise survey of the site prior to the development being undertaken, and undertaken at appropriate locations adjacent to or suitably equivalent to, the noise sensitive locations Sample measurement periods should be no less than 15 minutes, and the total measurement period should encompass the times of plant operations ( i.e 24 hours) A 7 day survey is recommended, but not compulsory.

iii Noise sensitive properties can be residential or commercial or public buildings This should be determined on

a site specific basis.

iv.The maximum noise level should be in terms of the LAeq parameter measured over a sample period of typically 2-3 minutes for continuous operating plant or over the longer period for any plant which includes cyclic changes in noise level It should be measured when the plant is operating normally.

v.The table also provides a noise limit in terms of NR (noise rating criteria) The overriding criteria is proposed

as the dBA parameter, but an excessive exceedance of the NR criteria at any frequency is not desirable.

vi.Where a plant room is likely to have a noise level in excess of 85 dBA and operate continuously during

vii Noise from standby generators and associated equipment should be no more than 10 dB above the noise level in that respective internal area The noise level during the operation of smoke control systems (including smoke spill fans and air pressurization fans ) shall not exceed 65 dBA in occupied spaces or 5 dBA above the ambient noise levels, to a maximum of 80 dBA Noise levels in fire – isolated exits shall not exceed 80 dBA.
