Volume Three Appendix 14 reconfigured or additional antennas installed subject to there being no increase in the overall height of the mast and attached antennas. 3. Antennas mounted on the roof of buildings shall not extend more than 5m above the maximum height of the roof of any existing building. Buildings 4. Any buildings, excluding masts, exhaust flues, antennas and air conditioning equipment shall not exceed a maximum building height of 10 metres. For the avoidance of doubt, building height means the vertical distance between ground level at any point and the highest part of the building immediately above that point. 5. For the avoidance of doubt, building height may be measured by either a rolling height method, or average height of the periphery of the building, whichever is the greater. Except this shall not restrict the maintenance, upgrading and replacement of any existing building where it infringes this condition provided there is no additional exceedance of the standards with this condition. Noise 6. Any new noise generating equipment (excluding any engine alternator required for emergency backup power generation) shall not exceed the following noise limits at a notional boundary 20m from the façade of any dwelling, or the site boundary, whichever is the closer to the dwelling: 7.00 am – 10.00 pm on any day: Leq 55 dBA 10.00 pm – 7.00 am on any day: Leq 45 dBA 7. Where existing site noise already exceeds the levels in condition 5 above, that any new noise generating equipment (excluding any engine alternator required for emergency backup power generation and/or load shedding) shall cumulatively in combination with any other noise generating equipment on the site not result in any increase in existing noise levels received at any other property boundary. A noise assessment may need to be submitted as part of any outline plan (depending on circumstances such as the nature of the noise generating equipment, remoteness of the site, and proximity to boundaries) to confirm the existing noise levels and predicted new noise levels to confirm compliance with this condition. 8. For any new engine alternator required for emergency backup power generation and/or load shedding that exceeds the noise limits is Condition 5 above, that an outline plan shall be required that demonstrates how the equipment and any mitigation is the best practicable option (BPO) to ensure that noise levels do not exceed a reasonable level. Radiofrequency Exposures 9. That all equipment transmitting radio frequency energy shall comply with the limits for public exposure in New Zealand Standard NZS2772.1:1999 at any place where the public has reasonable access. Outline Plans 10. That no outline plan shall be required for any internal building works that do not result in any increases in noise emissions, or for the replacement of any antennas with antennas of similar size provided that there is no overall increase in the overall height of the facility.
