An overview of the cognitive and biological effects of city nighttime illumination including a London case study.
Current scientific research demonstrates how critical the effects of city nighttime illumination are upon cognitive and biological health – which needs to be adequately acknowledged, understood and addressed by conscious cities and the plans they develop.
Historic Urban Settings, LED Illumination and its Impact on Nighttime Perception, Visual Appearance, and Cultural Heritage Identity.
Many cities, towns and villages around the world have adopted new Lighting Emitting Diode (LED) technology in order to save energy, operational and maintenance costs. While energy-efficient, these light sources have a critical effect on the appearance of historic sites at night – and the technology has unique properties and numerous inherent drawbacks that present challenges to decision makers as well as inexperienced lighting professionals.
