The Institution of Lighting Professionals (ILP) have partnered with BRE Academy to supply their expertise to tackle the lighting skills gap in industry.
Artificial lighting has transformed the way that we live through reducing dependence on changeable natural light – allowing us to expand the hours we can work and enjoy free time, all year round.
Nevertheless, with artificial light it is about getting the right light, in the right place, at the right time. Without this, developments risk being a source of annoyance to people, and harmful to wildlife, for example, undermining enjoyment of the countryside or detracting from views of the night sky.
This Friday Fives blog post is designed to shine a light on some of the most important considerations and questions you should be asking when assessing a scheme’s light pollution potential.
1. Consider the effect on light levels outside development spaces
Does a new development proposal (or a major change to an existing one) materially alter light levels outside the development and/or have the potential to adversely affect the use or enjoyment of nearby buildings or open spaces?
2. Assess EXISTING lighting at the location
Does an existing lighting installation make the proposed location for development unsuitable? For example, does existing ratification light have a significant effect on the locality, or will users of the proposed development (e.g. hospital) be particularly sensitive to this lighting intrusion.
3. Protected sites or species and effects on wildlife
Does the proposal have a significant impact on a protected site or species, for example, is it located on or adjacent to a European Site of Specific Interest (SSI)? Additionally, are any forms of artificial light with a potentially high impact on wildlife (e.g. white or ultraviolet light) being proposed near to sensitive wildlife receptors or areas, including where that light shines on water?
4. Areas of protected night sky
Is the development in or near a protected area of dark sky or an intrinsically dark landscape where it may be desirable to minimise artificial light sources?
5. Building materials for the proposed development and their interaction with light
Does the proposed development include smooth, reflective building materials, with large horizontal expanses of glass; particularly near water bodies (this in particular may create polarised light pollution that can affect wildlife behaviour)?
These are just some of the factors in ensuring a development is adhering to lighting legislation, and is not providing any nuisance to people and the environment.
The legislation surrounding artificial light and clarity over who is responsible for adhering to lighting procedure within a new development is often not covered extensively and consequently remains a key area where developments fail to meet regulatory requirements.
