Association of perceptions of artificial light-at-night, light-emitting device usage and environmental noise
Espey, Brian (2022)Exposure to artificial light-at-night (ALAN) is increasing globally, and there are concerns around how ALAN may impact sleep, psychological and physical health. However, there is a lack of evidence in the literature on how ... -
Direct measurement of the contribution of street lighting to satellite observations of nighttime light emissions from urban areas
Espey, Brian (2021)Nighttime light emissions are increasing in most countries worldwide, but which types of lighting are responsible for the increase remains unknown. Also unknown is what fraction of outdoor light emissions and associated ... -
Empirical Modelling of Public Lighting Emission Functions
Espey, Brian (2021)Study of light at night has increased in recent decades due to the recognition of its impact on the environment, potential health concerns, as well as both the financial and carbon cost of energy waste. The advent of more ... -
Night: The Other Side of the Enivronmental Coin
