Slide 19: Façade insulation assessment
19 5. Façade insulation assessment • AECOM was commissioned by AGL Energy to conduct a façade sound insulation assessment at five residences located at the Coopers Gap Wind Farm site in July 2016 • The residences were of different materials: • wood, tin, concrete, fibro, weatherboard • The QLD Code
Slide 20: Façade level testing

Slide 27: Conclusion
27 5. Conclusion Found the sound insulation indices of five different façade constructions common to the area – estimated wind farm noise attenuation of 8-13 dB(A) for the tested spaces. Estimated internal wind farm noise levels based on modelled data. Internal wind noise expected to range between 1

Slide 29: QLD wind farm state code requirements
29 5. QLD wind farm state code requirements Noise levels at sensitive receptors: • PO11 and PO12 – these state the levels you should not exceed Construction noise: • PO13 – should minimise noise from construction. We recommend a Construction Environment Management Plan (CEMP) should be developed.
Slide 30: QLD Code noise limits

Slide 34: Shadow Flicker Assessment
Shadow Flicker Assessment Rhys Brown AECOM Brisbane Acoustics Team 25 August 2016
Slide 35: What is shadow flicker?
35 6. What is shadow flicker? The rotating blades of wind turbines may cast flickering shadows, depending on the position of the turbine, sun and receptor When the sun is low in the sky, the length of the shadows cast by the turbine increase, increasing the area around the turbine affected by shadow
Slide 36: Should we be concerned?
36 6. Should we be concerned? Some people can consider shadow flicker a nuisance Epileptic seizures can be triggered by light flashes in the range of 5 – 30 Hz Flickering created by turbines is in the range of 0.6 – 1 Hz » Coopers Gap Wind Farm CCC 25 August 2016
Slide 37: Queensland Wind Farm State Code
37 6. Queensland Wind Farm State Code PO4 Development avoids or minimises shadow flicker impacts on existing or approved sensitive land uses. AO4.1 Shadow flicker assessment The modelled blade shadow flicker impact on any existing or approved sensitive land use(s) does not exceed 30 hours per annum
Slide 38: Assessed properties
38 6. Assessed properties Impact of shadow flicker only significant up to a distance of around 10 rotor diameters Beyond this distance shadow is diffused Shadow flicker here analysed at properties within 1.5km of turbine All participating landowners » Coopers Gap Wind Farm CCC 25 August 2016
Slide 39: Modelling shadow flicker
39 6. Modelling shadow flicker Model Inputs: • Terrain • House locations • EIS turbine locations • Bureau of meteorology data 50 Shadow flicker duration can be m very sensitive to location One end of a property may experience none – the other end may exceed Conservative approach taken – maximum valu
Slide 40: Modelling shadow flicker – worst case
40 6. Modelling shadow flicker – worst case Assumes: • Full sun • Sun perpendicular to blades • Blades always spinning Does not account for: • Intervening vegetation • Direction of the wind (and hence the rotor plane of the wind turbine) • Weather (particularly cloud cover) • General visibility (inc
Slide 41: Modelling shadow flicker – accounting for cloud cover
6. Modelling shadow flicker – accounting for 41 cloud cover QLD Planning Guideline accounts for cloud cover and/or scheduling operation. Reduced limit of 10 hours per year shadow flicker. Still does not account for: • Blades not spinning in low wind • Intervening vegetation • Direction of the wind •

Slide 44: Modelling output
6. Modelling output 44 • Shadow flicker experienced at seven properties at Coopers Gap • Exceeding at seven – all participating landowners • With cloud cover – five experience shadow flicker in excess of limits • Conservative estimate – not accounting for many factors that reduce shadow flicker • Ma
