What factors are relevant when considering possible ecological impacts of lighting? Use of modern white light sources that filter out blue or ultraviolet light may mitigate these effects, as well as offering superior directional control. Where plans are being prepared under the transitional arrangements set out in Annex 1 to the revised National Planning Policy Framework, the policies in the previous version of the framework published in 2012 will continue to apply, as will any previous guidance which has been superseded since the new framework was published in July 2018.

Consideration can also be given to whether the proposed lighting is purely for decorative purposes as opposed to being needed for functional reasons such as security. Glare is the uncomfortable brightness of a light source due to the excessive contrast between bright and dark areas in the field of view. As there are many buildings scattered in Hong Kong, artificial lighting is omnipresent. For example, large differences in adjacent lit areas can mask activity in shadow and cause areas of high contrast or glare. For more information view the help. The following is a list of common artificial light nuisances that amount to pollution if they are not well positioned or maintained properly: 1.

The use of lighting only when the light is required can have a number of benefits, including minimising light pollution, reducing energy consumption, reducing harm to wildlife and improving people’s ability to enjoy the night sky: Paragraph: 004 Reference ID: 31-004-20191101. Bright artificial light on coastlines may deter females from coming ashore to lay their eggs. Excessive groupings of light that are bright and confusing, commonly found in over-lit cities and inhabited areas. Light that is directed downwards to minimize light pollution is called shielded lights (or full cut-off). Lighting could also be dimmed to minimise its visual impact at times of reduced need or increased sensitivity. What factors can be considered when assessing whether a development proposal might have implications for light pollution? Lighting schemes could be turned off when not needed (‘part-night lighting’) to reduce any potential adverse effects - e.g. a hospital) may be particularly sensitive to light intrusion from the existing light source. Light pollution is defined as “the inappropriate or excessive use of artificial light” so as to cause a nuisance to the surrounding environment. Light pollution has been, traditionally, seen as concentrating near or within high population areas, due to the high use of nighttime lights along streets, public areas, residences, and businesses. The ability of some building materials to polarise light may cause insects, birds and other wildlife to mistake the material for water. Travel terminals such as airports and harbours 2. Is the development in or near a protected area of dark sky or an intrinsically dark landscape where new lighting would be conspicuously out of keeping with local nocturnal light levels, making it desirable to minimise or avoid new lighting? Lighting near or above the horizontal is usually to be avoided to reduce glare and sky glow (the brightening of the night sky). Light pollution can mean visible light disruptions from flooding of too much man-made light (as in the example of the city lights); it can also mean a lack of light – again, city lights take away a form of natural illumination and replace it with an artificial means; and it can also mean changes to light … All content is available under the Open Government Licence v3.0, except where otherwise stated, Ministry of Housing, Communities & Local Government.

In particular, some types of premises (including prisons, harbour premises, airports and transport depots where high levels of light may be required for safety and security reasons) are exempt from the statutory nuisance regime for artificial light, so it is even more important to get the lighting design for these premises right at the outset. Light pollution is a term that usually refers to outdoor artificial light that is considered excessive or obtrusive, described by the Campaign for Dark Skies as ‘artificial light which shines where it is neither wanted, nor needed’.. What causes light pollution is not only the street lights that are always on at night but also lights that people keep on at their homes. More lighting does not necessarily mean better lighting.

Impacts on sensitive ecological receptors throughout the year, or at particular times (eg during bird migrations) may be mitigated by the design of the lighting or by turning it off or down at sensitive times. Schemes designed for those more likely to be older or visually impaired may require higher levels of light and enhanced contrast, together with more control, as the negative effects of glare also increase with age. Some examples of causes of light pollution that we find in cities and urban centers are: She is a sustainability expert and author whose work has been published by the New York Times and National Geographic, among others. when driving vehicles), health impacts arising from impaired sleep, cause annoyance to people, compromise an existing dark landscape and/or adversely affect natural systems (e.g. We’ll send you a link to a feedback form. previous version of the framework published in 2012, setting appropriate conditions at the planning stage, consideration of bats in lighting projects, Handbook for scoping projects: environmental impact assessment, Artificial light nuisances: how councils deal with complaints, Open space, sports and recreation facilities, public rights of way and local green space, Coronavirus (COVID-19): guidance and support, Transparency and freedom of information releases, the artificial light has a significant effect on the locality; and/or.

Does the proposed development include smooth, reflective building materials, including large horizontal expanses of glass, particularly near water bodies? Examples of light pollution As is logical, light pollution is mainly located in urban centers and in illuminated roads, since they are spaces where human presence is greater and, consequently, also artificial lighting. Paragraph: 003 Reference ID: 31-003-20191101.

It is particularly a problem if you leave in, or near, a city or town. Impacts on other activities that rely on low levels of light such as astronomy may also be a consideration, but will need to be considered in terms of both their severity and alongside the wider benefits of the development. Before our nights were drenched with light, people relied on other strategies to navigate their worlds; the moon and stars were valued for their practical luminosity, people knew their neighborhoods and homes intimately, senses were more finely tuned since sight was hampered. In combination with optical good practice aimed at limiting light pollution, efficient lamp and luminaire selection are important considerations to minimise energy use and associated carbon emissions. The Clean Neighbourhoods and Environment Act 2005 makes "exterior light emitted from premises so as to be prejudicial to health or a nuisance" a criminal offence. It has the potential to become what is termed ‘light pollution’ or ‘obtrusive light’, and not all modern lighting is suitable in all locations. Light pollution is caused by poorly designed or unnecessary light shining wastefully where it is not needed… and it is increasing. The following questions indicate matters that may need to be considered in relation to managing the effects of light pollution: Does an existing lighting installation make the proposed location for a development unsuitable, or suitable only with appropriate mitigation? The impact the problem has on wildlife is especially disturbing – well it's all disturbing. The specific nature of any consideration will depend on the features of any protected site or presence of any protected species. Demonstrating Light Pollution and Shielding This demonstration will illustrate the effects of lighting on our view of the night sky and how shielding can reduce light pollution while at the same time making the lighting more effective. If you’d like an email alert when changes are made to planning guidance please subscribe.
