1 Executive Summary

An appropriate lighting scheme for the site has been assessed in order to establish its effects on the surrounding environment and neighbouring properties.

The lighting scheme in this report is to be viewed as a lighting design strategy rather than a detailed design solution. It is recommended that the lighting strategy outlined in this report is adopted including criteria, luminaries, switching methods, lamp types etc. by the developer’s designers when undertaking the full external lighting design of the site.

This lighting scheme ensures that there will be zero illuminance from the proposed lighting scheme at the site boundary. Lighting as proposed will not cause excessive glare to neighbouring residential properties from this site. The majority of the fittings will not be visible to neighbouring domestic properties. Consideration has been given to mitigating the impact on the bats in the area, and in particular their flight paths through the site. Drawing E02 shows that the effect on the night sky will be negligible inside the site and zero outside the site. An adequate level of lighting will be provided for site tasks and amenity in accordance with the Clients Risk Assessment and Method Statements, whilst maintaining a minimal impact on the site surroundings, environment and neighbouring properties. There is no requirement for lighting for security.

2 Introduction

2.1 Scope of External Lighting Report This report has been prepared in order to establish the potential effects of the proposed development’s fixed lighting installation on the bat conservation areas and the site surrounding areas. The report accompanies the planning application for the proposed IBA Facility, hereafter referred to as the ‘site’.

2.2 Objectives The general objective of this report is to assess the impact of a suitable lighting scheme for the proposed IBF Facility on the surrounding area and environment.

Specific objectives of the proposed lighting scheme when fully designed include:

� To limit light pollution and sky glow.

� To limit obtrusive light, spill light / trespass light and glare to neighbouring land and properties.

� To mitigate the effects of the lighting scheme on bats.

� To provide an adequate level of illuminance for the proposed exterior areas, in accordance with the Clients Risk Assessment and Method Statements. The lighting is to be controlled via photocell and time clock, so that it is only switched on during the site opening hours of 7am – 7pm. (The time clock will bring the lighting on at 7am and the photocell will switch it off at dawn, then the photocell will bring the lighting back on at dusk and the time clock will switch it off at 7pm.) The only exception to this is the luminaire lighting the material handling area which will be manually switched on/off from the IBA Processing Plant building as and when it is required, within the site opening hours.

3 Assessment Methodology

An appropriate lighting scheme for the site has been assessed using standard industry software Relux.

Relux is a computer calculation package which utilizes 3D modelling to model the real world output of chosen light fittings. The results from the computer model produce the contour lines detailed on drawing D134633/E01.

The lighting outputs have been calculated with all the luminaries switched on. However, this level of illuminance will only be during the site working hours and will represent the maximum level of illuminance at any time, as the levels will be reduced when the manually switched task lighting over the material handling area is switched off. All external lighting will switched off via a time clock at the end of the site opening period. From these calculations, drawings illustrating the illuminance levels throughout the site and at the boundary have been produced so that the lightings scheme’s impact can be assessed. Refer to Drawing E01 for detail. The calculation model (Lux levels on drawing) does not include the proposed planting / hedgerows / trees, however this is accounted for when assessing and making conclusions about the light spill.

Light trespass has been assessed and the line of sight from neighbouring residential properties has also been considered.

The sky glow impact from the site has been calculated for the ‘worst case scenario’, with all the luminaries switched on. For detail see Drawing E02.

Full calculations have been included in Appendix 5.

4 The Proposed Lighting Scheme

The lighting scheme outlined in this report is to be viewed as a lighting design strategy rather than a detailed design solution.

4.1 General Lighting throughout the site will only be operational during the site opening hours. The site opening hours are 7am – 7pm daily. The operating hours will be 8am – 6pm daily.

All luminaires will utilise High Pressure Sodium lamps to reduce the impact on bats.

4.2 Recommended Lighting Values

Lighting levels have been designed in accordance with the Clients requirements and to mitigate the sites impact on bats. Consideration has been given to CIBSE Lighting Guides, SLL Code for Lighting 2006 – Obtrusive Light Guide, Guidance Notes on Reduction of Light Pollution, and BS 5489. However, the final agreed illuminance levels in which this report is based upon have been decided by the Client following their risk assessment, method statements and consideration of the site H&S strategy.

Recommended Levels

The recommended levels according to SLL Code for Lighting – Obtrusive Light Guide (refer to Annex 2 of this report) are as follows:

� Area Lighting for Lorry Area is 20-30 Lux Maintained Average (horizontal).

� Area Lighting for Loading Area is 50 Lux Maintained Average (horizontal) and 25 Lux Maintained Minimum (horizontal).

The recommended lighting levels according to SLL Code for lighting – General Areas in Outdoor Work Places (refer to Annex 3) are as follows:

� Walkways exclusively for pedestrians are 5 Lux Maintained Average (horizontal).

� Traffic areas for slowly moving vehicles (max 10 km/h) e.g. bicycles, trucks and excavators is 10 Lux Maintained Average (horizontal).

� Pedestrian passages, vehicle turning, loading and unloading points is 30 Lux Maintained Average (horizontal).

� Lighting requirements for safety in medium risk areas is 20 Lux.

� Lighting requirements for safety in high risk areas is 50 Lux.

Agreed Levels for this site

Good uniformity across the defined areas is not achievable due to restrictions placed by the client on the positioning of luminaires. See Appendix 6 for definition of areas.

� Area 1 – This area will be lit using portable task lighting as required, during site operating hours. This report considers the fixed lighting installation only.

� Area 2 – Bat flight path to be unlit.

� Area 3 – Turning circle and Weighbridge to be unlit. Maximum illuminance 3 Lux at ground level due to requirements for bat mitigation.

� Area 4 – Access road to be unlit.

� Area 5 – MRF area, site offices, staff car-parking area to be lit to an average illuminance of 5 Lux across whole area using a combination of low level bollard lighting and building mounted luminaires. Lighting to be concentrated around the front of the buildings, storage containers and car parking spaces so that there is higher levels of illuminance in these areas, and as lower level as possible close to the bat flight path and in the vehicle circulation area, between the buildings, as this route will be lit by vehicle headlights.

� Area 6 – IBA Processing Yard to be illuminated to a minimum average illuminance of 20 Lux.

� Area 7 – Material handling area considered to be a high risk area, to be illuminated to an average illuminance level of 50 Lux.

4.3 Strategy for Minimising Obtrusive Light, Mitigating the Effect on Bats and Reducing the Visual Impact of the Lighting Scheme Careful consideration has been given to reducing obtrusive light during the hours when the site is lit and the visual impact of the lighting scheme during the day, whilst maintaining an adequate level of illuminance for its application on the site. Particular attention has been paid to minimising the presence of the scheme and any intrusion, glare or sky glow produced by the scheme.

There will be no security lighting anywhere on the site; therefore all lighting will be switched off when the site is closed.

Area 2, 3 & 4

To mitigate the impact of the lighting scheme on bats many areas of the site will remain unlit at all times. These include areas 2, 3 & 4. The main access route, turning circle and weighbridge will remain unlit to mitigate the impact on bats; this includes the old workshop that contains the bat roost. Luminaires have been chosen that have good control of light spill so that only the intended areas are lit.

Whitecleave Quarry

Area 5

In Area 5 a combination of low level bollard and building mounted luminaires have been utilised to reduce the impact on bats and so that the bat flight path in that area will remain unlit.

Where ever possible luminaires are to be orientated towards the site, away from the land outside the site to make them less intrusive. This has been particularly considered in Area 5 - the MRF area, site offices, staff car-parking area, ensuring that the majority of luminaires are orientated away from the residential properties. The light sources in this area will not be visible from the residential properties. Luminaires have been chosen that have good light control and cut off angles to reduce light spillage.

Area 6

The IBA Processing Yard shall be lit by a combination of column and building mounted luminaires. The mounting height in this area will be 8 metres. This area is less sensitive to bats which is why column mounted luminaires have been proposed. There is a bat flight path to the left of the yard behind the push walls and proposed hedgerows, this area will not be affected and will remain unlit, as illustrated by drawing E01.

The column mounted luminaires have been chosen to be as inconspicuous as possible. The luminaire, bracket and column shall all be coloured grey. The luminaries will be angled at a maximum of 10º above horizontal which will minimise sky glow whilst providing a wide light distribution at ground level reducing shadows produced from obstructions i.e. lorries, parked for loading. The luminaire itself has 0% upward light ratio, and the beam spread is controlled to within 50º from the vertical when the glass is horizontal. Therefore this would only increase to 60º when the luminaire is adjusted to 10º from the horizontal, which will still produce negligible upward light. It is also fitted with flat glass to reduce the visibility of the light source.

Area 7

A building mounted luminaire will be utilised to light the material handling area, this luminaire will be mounted at 8m at a 30º angle to horizontal, however this luminaire will be manually switched on/off as and when required up to site closing time.

General

The red line on drawing E01 represents 5 Lux and the purple, 1 Lux. The drawing shows that at worst case with all the luminaries switched on, there will be no light spill onto the boundary and that there will be minimal impact on the bat flight paths from the lighting scheme. Where possible it has been proposed that dense shrubs and woodland will be planted to help to shield and screen the lighting scheme. Consideration has been given to reducing the extent of illuminance falling on the building façade to reduce the visual impact of the site and buildings from a distance.

4.4 Strategy for Luminaire Types High Pressure Sodium (SON) lamps shall be utilised throughout the site, as recommended by the ecologists working on the project proposals, to mitigate the impact of the lighting scheme on the bats. The SON lamp will provide a Colour Rendering of approx 20 Ra which is acceptable for the application. Using this type of lamp will provide an energy efficient solution and will be Building Regulations Part L and BREEAM compliant. These luminaries, or equal and approved, have been chosen as they have been designed to be anti light pollution and low glare with good levels of efficiency between 50 – 80% for the chosen lamp types and low upward light ratio. All the luminaries are IP66 rated and impact resistant. See Appendix 4 – Schedule of Luminaries and Details.

4.5 Luminaire Control Strategy A photocell and programmable 7 day time clock are to be used to control the majority of the exterior lighting so that no luminaries will be left on during daylight hours or when the site is closed. The only exception to this is the lighting for the material handling area which will be manually switched on/off from the IBA Processing Plant building as and when it is required up to 7pm.

5 Assessment of the Impact of the Lighting Scheme

Drawing E01 shows the lighting scheme for the site, with the illuminance levels shown throughout the site and at the boundary. The calculation model was prepared using industry standard software, Relux. It shows that adequate levels of lighting have been achieved on the site with minimal effect on the surrounding area. There will be zero illuminance from the proposed lighting scheme at the site boundary. There will be a maximum of 3 Lux measured at any point on the bat flight path, but mostly the path will be completely unlit. And once the proposed site planting / hedgerows are in place the effect on the bats will be further reduced. Cowls and louvre attachments are available for the column mounted fittings as a retro fit item, but these will be unnecessary as long as the final luminaire choices and locations are as calculated.

Drawing E02 illustrates the additional sky glow caused by the lighting scheme. This calculation was provided by a simulation of a measuring reference plane approx 50m above the ground. The results show an average illuminance above the site of 0.43 Lux. This means that when the site is fully lit the sky glow will be approximately equivalent to the light produced by a full moon at 0.3 Lux, which is very low. The sky glow above the surroundings of the site will be negligible.

6 Conclusions

By adopting the lighting strategy including criteria, luminaries, switching methods, lamp types, etc. outlined in this report it can be concluded that:

� There will be minimal impact on bats due to the position of the luminaires and types. Also, due to the times bats emerge and the short hours that the lighting will be on for, there is little overlap between the two.

� There will be zero illuminance from the proposed lighting scheme at the site boundary.

� Lighting as proposed would not cause excessive glare to neighbouring domestic properties from this site.

� The majority of the luminaries will not be visible to neighbouring domestic properties.

� The effect on the night sky will be minimal inside the site and zero outside the site.

� The lighting scheme will be energy efficient utilising luminaires with an efficiency of between 50-80%, combined with energy efficient lighting controls.

� An adequate level of lighting can be provided for site tasks, amenity and security, whilst maintaining a minimal impact on the site surroundings, environment and neighbouring properties.

Lighting Guide LG6 CIBSE 1992. Outdoor Environment.

For the purpose of this report, the definitions given below apply:

Colour Rendering Index (CRI): A scale of the colour appearance of an object under a particular light source compared to its colour appearance under a reference light source. Expressed on a scale of 1 to 100 Ra, where 100 Ra represents the colour rendering of natural daylight i.e. perfect colour.

Illuminance: Illuminance is the quantity of light, or luminous flux, falling on a unit area of a surface. It is designated by the symbol E. The unit is the lux (lx). One lux equals one lumen per square metre (lm/m²).

Light Pollution: The spillage of light into areas where it is not required.

Light Trespass: Light that impacts on a surface outside of the area designed to be lit by a lighting installation.

Disability Glare: Glare which impairs the vision of objects but may not cause discomfort.

Discomfort Glare: Glare causing discomfort which may not impair the ability to see objects.

Photocell: A unit which senses light to control luminaires.

Curfew: The time after which stricter requirements (for the control of obtrusive light) will apply; often a condition of use of lighting applied by a government controlling authority, usually the local government (CIE, 2003).

Environmental Zones: Area where specific activities take place or are planned and where specific requirements for the restriction of obtrusive light are recommended. Zones are indicated by the zone rating (E1… E4) (CIE, 2003).

Obtrusive Light: Spill light which because of quantitative, directional or spectral attributes in a given context, gives rise to annoyance, discomfort, distraction or a reduction in the ability to see essential information (CIE, 2003).

Residential Property: Land upon which a dwelling exists (CIE, 2003).

Sky Glow: The brightening of the night sky caused by artificial lighting resulting from the reflection of radiation (visible and non-visible), scattered from the constituents of the atmosphere (gas molecules, aerosols and particulate matter), in the direction of observation. It comprises two separate components as follows:

(a) Natural sky glow - That part of the sky glow which is attributable to radiation from celestial sources and luminescent processes in the Earth’s upper atmosphere.

(b) Man-made sky glow - That part of the sky glow which is attributable to man-made sources of radiation (e.g. outdoor electric lighting), including radiation that is emitted directly upwards and radiation that is reflected from the surface of the Earth (CIE, 2003).

Spill Light (Stray Light): Light emitted by a lighting installation which falls outside the boundaries of the property for which the lighting installation is designed (CIE, 2003).
