Final answer:
For SSc Light Pollution Reduction, building-mounted luminaires should minimize upward light emission to prevent sky glow by using shielding and directing lamps downward. Advances in LED tech and automation have made these goals more achievable. Concerns about light pollution also include impacts on human and wildlife health beyond global warming and energy conservation.
Step-by-step explanation:
For SSc Light Pollution Reduction efforts that concern building-mounted luminaires, the requirement is focused on minimizing the unnecessary upward emission of light that contributes to sky glow. These are measures often embraced by environmentalists and those concerned with global warming because reducing light pollution also conserves energy and mitigates negative impacts on ecosystems. To comply with these requirements, lighting designers must employ strategies such as shielding lamps, angling lights downward, and using lower-intensity bulbs, possibly in conjunction with motion sensors or timers to further reduce light output when not needed.
With the advancement in LED technology and automated lighting, designers have additional tools to achieve these objectives. LEDs can be more easily directed and controlled, allowing for precise application of light and reducing the tendency for light spill. Automated systems can further enhance energy efficiency and light pollution reduction by turning lights off or adjusting their intensity based on real-time conditions.
The concerns about light pollution extend beyond astronomical interests to include various non-astronomical issues. For example, excessive artificial lighting has been linked to disruptions of circadian rhythms in humans and wildlife, which can lead to health issues and biological disruptions. Highlighting these reasons appeals to a broader audience and reinforces the importance of sustainable lighting design practices.
