Ecobuild 2014: How do we solve a problem like light pollution?

Pete Lummis

Understanding

and tackling

light pollution

“Lighting itself is not a problem;

it only becomes a problem where

it is excessive;

poorly designed,

badly installed

or poorly maintained.”

Supplementary Planning Guidance

External Artificial Lighting

Obtrusive light

(light pollution)

Sky glow

Glare

Light intrusion

Local Plan to 2036 1 LP2036 - Managing Development

Draft Policy MD 13

A sustainable development proposal will be

acceptable where a high standard of amenity is

provided for existing and future users of both the

proposed development and surroundings.

The design and access statement will demonstrate

how the proposed development addresses:..

d) the effects of overshadowing and the need for artificial light; The potential for adverse impacts of air pollution, obtrusive light* and the contamination of

land, groundwater or surface water;

*Obtrusive lightLight pollution that includes the brightening of the night sky (sky glow), uncomfortably bright light (glare) and light spilled beyond the area being lit (light intrusion).

Sky glow =

reflected

Direct

Upward Light

Poorly designed light source

giving direct upward light

Glare =

viewed

source

intensity

Light

intrusion

Tackling light pollution

1. Education

a) Understanding the equipment

Floodlights

Symmetrical Floodlight

Asymmetrical Floodlight

Double-asymmetrical

Floodlight


1. Education

b)Specifying the equipment

Type of luminaire

Type of lamp and lumen output


1. Education

c) Designing the lighting scheme

Type of luminaire

Type of lamp and lumen output

Lighting levels

Iso-Lux Contour levels showing spill light down to 1 lux


1. Education

d) Installing the equipment

Type of luminaire – aiming angle

Mounting Height


2. Planning Process

Check design is appropriate,

condition and install as per design


3. Public awareness
