Dark Sky Overlay

The Dark Sky Overlay Code from the Queensland Government is a regulatory framework aimed at preserving and protecting the natural darkness of the night sky. This overlay code seeks to minimise light pollution and its adverse effects on astronomical observations, wildlife behaviour, human health, and the overall quality of the night-time environment.

Key components of the Dark Sky Overlay Code may include:

  1. Lighting Restrictions: The code typically imposes restrictions on the types of lighting fixtures permitted in designated dark sky areas, requiring the use of fully shielded fixtures that direct light downward and minimize upward glare.
  2. Lighting Intensity Limits: There may be limits on the intensity or illumination of outdoor lighting to ensure that artificial illumination does not overpower the natural brightness of the night sky.
  3. Curfew Hours: Some dark sky overlay codes may establish curfew hours during which outdoor lighting must be reduced or turned off altogether to allow for optimal stargazing and nocturnal wildlife activities.
  4. Education and Outreach: The code may include provisions for public education and outreach efforts to raise awareness about the importance of dark skies and the impacts of light pollution.

WAVES Testing, Research and Consulting can provide valuable assistance with various aspects of development application preparation, lighting design guidance, and review, as well as conducting light audits and artificial light at night (ALAN) surveys to ensure compliance with the Dark Sky Overlay Code:

  1. Development Application Preparation: WAVES assists developers in preparing development applications that adhere to the requirements of the Dark Sky Overlay Code. We can evaluate proposed lighting plans and recommend strategies for minimising light pollution while meeting project objectives.
  2. Lighting Design Guidance: WAVES offers expert guidance on designing lighting systems that comply with dark sky regulations. This may involve recommending appropriate fixture types, light levels, light colour, and placement to minimize glare and avoid upward spill light.
  3. Review and Compliance: WAVES reviews lighting designs and development plans to ensure they meet the standards outlined in the Dark Sky Overlay Code. We can provide feedback and recommendations for adjustments to achieve compliance with the regulations.
  4. Light Audits: WAVES conduct on-site light audits to assess existing lighting conditions and identify sources of light pollution. We can measure light levels and quality, and provide recommendations for retrofitting or replacing fixtures to reduce light pollution and preserve the integrity of the night sky.

By leveraging our expertise in light measurement and design, WAVES Testing, Research and Consulting helps developers navigate the complexities of dark sky regulations and ensure that their projects contribute to the preservation of natural darkness and the enjoyment of the night sky for present and future generations, without blowing out budgets.
