LIGHTING ASSESSMENT
EXECUTIVE SUMMARY
Brentwood Group have been appointed to complete a Lighting Assessment to support a full planning
application for the extension of an existing Warehouse Distribution Centre at Bridgend, South Wales.
The site is existing and lies to the south of Bridgend on Waterton Industrial Estate and falls under
the administrative boundaries of the Bridgend County Borough Council.
The planning application is for the extension of the existing Warehouse on site together with the
expansion of the associated Cark Park and Lorry Park.
A lighting assessment has been undertaken to identify the conditions of the current site including
details of screening, topography, vegetation, buildings/structures and potential sources of existing
artificial lighting. The purpose of this is to identify vulnerable areas which may be affected by
obtrusive light; and to assess the potential effects on those areas from the new artificial lighting
proposed for the development.
The site location is on the outskirts of Bridgend and it has been assessed that the site and its
surroundings can be categorised within ILP Environmental Zone E3. This category applies to well
inhabited rural and urban settlements, small town centres of suburban locations. An Ecology Report
has been developed identifying that protected wildlife exists to the East of the site as such the
lighting must been designed to limit lighting to only the areas that require it.
Based on the Ecology Report The Lighting Strategy for the site has sought to minimise levels of
lighting through designing to the relevant British Standard; minimise the effects of obtrusive light on
existing and future vulnerable areas; and meet the obtrusive light limitation for exterior lighting
specified for ILP Environmental Zone E1.
The lighting assessment has identified the limited effects of obtrusive light on vulnerable areas, and
where needed has set out mitigation measures to further reduce those effects and meet the
requirements of ILP Environmental Zone E1 limits.
Based on this assessment and subject to the incorporation of the recommendations set out in this
report, it is considered that obtrusive lighting from the proposed Lighting Strategy does not pose a
constraint to the proposed development.

INTRODUCTION
2.1 Background
Brentwood Group were appointed to complete a Lighting Assessment in support of the full planning
application to Bridgend County Borough Council. The planning application is for the extension to the
existing LIDL Warehouse facility and expansion of the existing car and Lorry Parking areas.
2.2 Application Site
The existing LIDL Warehouse is located to the south of the town of Bridgend on Waterton Industrial
Estate. The site is on the southern edge of this Industrial Estate. A private rail track borders the
southern edge of the site with fields beyond. Open fields and woodland border the north eastern
and eastern side of the site. A car retail garage is located adjacent to the site on the north western
side of the site.
A plan showing the site is detailed below.

2.3 Proposed Development
The existing Warehouse facility is to be extended on the southern side of the building and in some
places up to the boundary of the site. The extension will be the same width and height of the existing
building.
In addition to the above the existing Car and Lorry Park are to be expanded and are likely to double
the size of the existing arrangement. It is understood that the expansion of the parking areas will
have the largest impact on the local ecology and wildlife.
2.4 Purpose of this Report
This report details the lighting strategy and a further assessment identifying the potential effects
from obtrusive light that may arise from the scheme which has been designed for the proposed
development
The Lighting Assessment will:
• Identify potential existing obtrusive light within and around the development site;
• Establish the minimum operational lighting required to safely and securely operate the
proposed development;
• Describe potential effects on vulnerable areas as a result of obtrusive light from the proposed
development.
• Set out details of the lighting strategy which includes measures to minimise obtrusive light
following completion.

POLICY CONTEXT
The policy context relevant to the assessment of obtrusive light is summarised in this section, a
detailed overview of the policy context is provided in Appendix A.
3.1 Clean Neighbourhoods and Environment Act
The Clean Neighbourhoods and Environment Act 2005 (CNEA) amended Section 79 of the
Environmental Protection Act 1990 by extending the statutory nuisance regime to include light
nuisance, by stating the following:
“(fb)…artificial light emitted from premises so as to be prejudicial to health or a nuisance…”
“Subsection (1)(fb) does not apply to artificial light emitted from - (a) an airport; (b) harbour premises;
(c) railway premises, not being relevant separate railway premises; (d) tramway premises; (e) a bus
station and any associated facilities; (f) a public service vehicle operating centre; (g) a goods vehicle
operating centre; (h) a lighthouse; (i) a prison.”
Artificial light can be considered to be a statutory nuisance unless it is from exempt premises.
3.2 National Policy
National Planning Policy Framework and Guidance
The Government’s over-arching advice regarding the operation of the planning system is set out in
the National Planning Policy Framework.
Paragraph 125 of the National Planning Policy Framework (NPPF) states;
“By encouraging good design, planning policies and decisions should limit the impact of light
pollution from artificial light on local amenity, intrinsically dark landscapes and nature conservation”.
The Government’s Planning Practice Guidance (2014) web-based resource presents specific
guidance on light pollution (obtrusive light).

GUIDANCE
4.1 Obtrusive Light
Guidance on obtrusive light is set out within the following guidance documents, further detail is
provided in Appendix A:
• Commission Internationale De L’Eclairage (CIE) 150:2003
• CIE 126-1997. Guidelines for Minimising Sky Glow
• The Institution of Lighting Professionals (ILP) Guidance Notes for the Reduction of
Obtrusive Light, 2011
• ILP Professional Lighting Guide 04: Guidance on Undertaking Environmental Lighting

METHODOLOGY
This section provides an outline of methods and procedures undertaken in producing the lighting
assessment including how the baseline lighting conditions were determined, and the assessment
process undertaken.
5.1 Desk Based Information
A desktop review of the site and surrounding area has been undertaken to identify areas which are
light sensitive and to establish the appropriate ILP Environmental Zone classification for the
Application Site as defined by the ILP’s Guidance Notes for Obtrusive Light (2011).
The following sources of publicly available information were reviewed: -
• Ordnance Survey mapping and aerial photography (2016);
• Google Street View (2015); and
• Defra Multi-Agency Geographic Information for the Countryside (MAGIC) Map Application
(2016).
The desk-based information enables a framework to be established for the assessment,
unfortunately the aerial photography and Google Street View may not be up to date and therefore
cannot be relied on as being definitive.
5.2 Sensitive Receptors
Sensitive receptors within and immediately around the Application Site have been identified
considering the recommendations in ILP Guide 04 (2013) and drawing on an Ecological Constraints
Assessment undertaken for the Application Site.
5.3 ILP Environmental Zone
The ILP have established Environmental Zones for exterior lighting based on the existing external
ambient lighting levels in the area (see Table 5-1).
The ILP Environmental Zone classification for the Application Site has been determined based on
professional judgement.
The ILP Environmental Zone classification determines the obtrusive light limitations for exterior
lighting installations for that area. The specification of the limits for each ILP Environmental Zone
are reproduced from the ILP guide (2011) in Appendix B.

5.4 Assessment
A qualitative assessment has been completed to establish the possible effects of obtrusive light that
may arise from the proposed development. This includes the consideration of potential adverse
effects of the following three components of obtrusive light (as expressed in Figure 3-1):
• Sky glow – the brightening of the night sky above areas with large amounts of artificial light
which may be reflected from illuminated surfaces or come from direct upward lighting
installations
• Glare – the brightness of a light source which is uncomfortable when viewed against a dark
background. This is mostly experienced when light sources are not covered by a shield or
directed by a suitable lens / reflector set up.
• Light intrusion – when light affects areas beyond the boundary of the area which is to be lit.
This is also known as ‘spill’ or ‘trespass’ and may cause nuisance or disturbance to sensitive
receptors.

Table 5-2: Diagrammatic Representation of Types of Obtrusive Light (ILP, 2011)
A Lighting Strategy has been developed. (see Appendix E) this provides a quantitative analysis with
suitable calculations in order to determine the light levels from the proposed design for sky glow,
glare and light intrusion. The Lighting Strategy has been developed in order to meet the specified
limitations of the relevant ILP Environmental Zone.

EXISTING CONDITIONS
6.1 The Application Site
The Application Site comprises the existing LIDL Warehouse with tarmac car parks and lorry parks.
The site is access from a single entry point from an un-named road off the A48 Cowbridge Road.
The Warehouse is shielded from the road by the trees and shrubs surrounding the site on the east,
south and western sides. A Ford Retail garage is located on the northern side and the site entrance
is to the left hand side of this garage and the Warehouse is located behind this garage.
A Ford Production facility is the next facility to the east of the site and a small wooded area separates
to two sites. A rail line connecting the ford facility to the main rail line exists to the south of the site
with fields the other side of this line. The A48 main road passes the western side of the site with
fields on the opposite side of this road.
The existing building is an existing operational LIDL warehouse with regular traffic including cars
and lorries visiting the site daily. The site is operational 24hrs a day.
6.2 The Application Site Surroundings
The site exists on the Waterton Industrial Estate which also includes the Ford Production Facility
and other retail, industrial and commercial premises. The Bridgend Industrial Estate exists further
to the north of the site. Farmland is predominant to the south and west of the site.
6.3 Sensitive Receptors
Existing sensitive receptors have been identified in the assessment of the Application Site and
surrounding area and are detailed in Table 6-1 below. As the site is existing the future receptors will
be the same as the existing.
Table 6-1: Existing
Receptor Description
Existing local
residents (off-site)
There are no residential properties immediately adjacent to the site.
The nearest residential properties are located within the village of
Corntown approximately 0.5km from the site. Due to the landscape
topology it is not possible to view the site from these properties.
Motorist, cyclists,
equestrian &
pedestrians
Users of roads either adjacent to the Application Site or with views of
it, including the following:
The A48 runs to the west of the site. The main entrance to the site is
off an unnamed road which leads from this road into the Waterton
Industrial Estate.

Railway An existing single rail line exists to the south of the site and this
appears to be associated with the Ford Motor factory adjacent.
Heritage There are no designated heritage assets within the Application Site or
surroundings which are anticipated to be affected by obtrusive light.
Ecology Artificial lighting can be very damaging to nocturnal wildlife. At
Waterton Industrial Park this is likely to have potential to affect bats,
dormouse, hedgehog, owls etc. The lighting needs to avoid
unnecessary light spilling into areas of retained or mitigation habitat,
and wildlife friendly planting.
The number of roosting bats on or near to the Application site was
unknown at the time this report was written. Bats are known to be
sensitive to intensity and intrusion of the light into habitats past the
borders of the intentionally lit area. Any form of obtrusive light has the
potential to cause disturbances to light-sensitive and nocturnal
species.
6.4 ILP Environmental Zone
The Application Site and its surroundings have been identified from maps as a suburban area. As it
has been identified that the lighting may affect the local wildlife it has been thought that the site will
be categorised as ILP Environmental Zone E3 as set out in ILP Guidance Notes for the Reduction
of Obtrusive Light GN01:2011 (see Appendix A).

LIGHTING REQUIREMENTS AND STRATEGY
7.1 Operational Lighting Requirements
Operational lighting is required for the proposed scheme to allow safe use of the development once
it is occupied. The primary use of the lighting will be to illuminate footpaths between the various
buildings and outdoor areas that will be used for socialising.
It is the intention to have the main car park and all service areas below ground. Consideration has
been given to the entrance to these areas to ensure that adequate lighting is provided for safe
access.
7.2 Lighting Strategy
Design Objectives
The key design objective for the Lighting Strategy has been for luminaires and the design specified
to seek to achieve the limitations set for obtrusive lighting for ILP Environmental Zone E3. The
limitations for exterior lighting for each ILP Environmental Zone are provided in Appendix A.
Other general design objectives that have been considered and incorporated in the Lighting Strategy
to restrict obtrusive light affecting sensitive receptors are summarised in Table 5-1, along with how
the Lighting Strategy addresses each objective.
Proposed Lighting Strategy
The Lighting Strategy has been mindful of the minimum lighting levels required to meet the following
standards and guidance documents and also to ensure that it is sympathetic with the specifications
set out for the ILP Environmental Zone specified.
• BS EN 5489-1:2013 Code of Practice for the design of road lighting – Part 1: Lighting of
roads and public amenity areas
• CIBSE (2016) Lighting Guide 06: The Outdoor Environment
The Lighting Strategy provides a location plan for the luminaires throughout the site and a summary
of the lux levels across the site. The design set out has been tested using computational modelling
to understand whether it meets the lighting specifications for ILP Environmental Zone E3.

Table 7-1: Design Objectives and Lighting Strategy specification
Design Objective Lighting Strategy specification
Lighting should be directed away (or
controlled) from all the sensitive
receptors identified in Section 6.3 to
prevent obtrusive light (glare or
intrusion) adversely affecting them.
The Lighting Strategy has been developed specifically
to illuminate parking areas, vehicle access routes,
loading bays etc while avoiding obtrusive light to other
areas of the site.
Target: Light Intrusion limit (lux) into windows for ILP
Environmental Zone E1 is 0 lux pre-curfew and 0 lux
post-curfew.
Based on the type of luminaires chosen and their
positioning around site it is not anticipated that Light
Intrusion will cause a problem.
Target: Luminaire intensity limit (candelas) for ILP
Environmental Zone E1 is 2,500 candelas pre-curfew
and 0 candelas post-curfew.
A number of test co-ordinates were selected to
measure luminous intensity; all co-ordinates are well
below the pre-curfew and pot curfew limits.
Minimising light break-out above the
horizontal using ‘full cut-off’ lighting
systems where required. This is
achieved through ensuring the
lighting units are correctly placed
and by placing them at a height
such that they can be directed
downwards rather than horizontally.
Target: Sky Glow ULR limit (max %) for ILP
Environmental Zone E2 is 0%.
Luminaires to be used throughout the site will be
column mounted floodlights with the source lamp
recessed into the body of the luminaire facing down
ensuring 0% upward light output. The maximum height
of the low-level luminaire will be 1150mm. Height of
wall mounted luminaires to typically 2500mm.

The manufacturer stated has been used for the
purpose of the calculation. Other manufacturers offer
similar products and the final product to be used will be
confirmed once the final design has been completed.
Lighting should be designed to
avoid reflectance from buildings and
plant – so external lighting should
be mounted onto buildings or on
lighting stands and directed to the
area where it is needed rather than
facing building facades.
Building Luminance is not relevant in this case as we
are not directly illuminating the building and lighting
designed is suitable controlled to prevent light spilling
onto buildings.

POTENTIAL EFFECTS AND MITIGATION
8.1 Introduction
This section assesses the potential effects of the operational phase Lighting Strategy proposed for
the development as described in Section 7, on the sensitive receptors that are identified in Section
6. It sets out measures to mitigate any potential effects from the operational lighting.
8.2 Operational Lighting
Existing Local Residents
There are no properties immediately adjacent to the site. The nearest residential properties are
located within the village of Corntown approximately 0.5km from the site. Due to the landscape
topology it is not possible to view the site from these properties.
The ‘Dark Sky’ type of luminaires chosen dictates that there will be no discernible sky glow viewable
from the local villages. The limits of ILP Environmental Zone E3 will be met and it is anticipated that
there will be no effects of obtrusive light in the form of sky glow.
Motorists, Cyclists, Equestrians and Pedestrians
The A48 roads is used by motorists, cyclists and pedestrians and runs to the West of the site. The
main entrance to the site is off this road. These users are particularly sensitive to glare effects from
obtrusive light.
Views of the Application Site are screened by existing vegetation, therefore it is anticipated that
there will be no effects from intrusion or glare from the proposed development on users of these
roads.
The ‘Dark Sky’ type of luminaires chosen dictates that there will be no discernible sky glow viewable.
The limits of ILP Environmental Zone E3 will be met and it is anticipated that there will be no effects
of obtrusive light, glare or sky glow from the proposed development on motorists, cyclists,
equestrians and pedestrians.
Ecological Receptors
Artificial lighting can be very damaging to nocturnal wildlife. At Waterton Industrial Park this is likely
to have potential to affect bats, dormouse, hedgehog, owls etc. The lighting plan produced ensures
that a safe working environment exists at the warehouse facility, but light is controlled and directed
to avoid unnecessary light spilling into areas of retained or mitigation habitat, and wildlife friendly
planting.
The ‘Dark Sky’ type of luminaires chosen dictates that there will be no discernible sky glow viewable.
The limits of ILP Environmental Zone E3 will be met and it is anticipated that there will be no effects
of obtrusive light, glare or sky glow from the proposed development on the local ecology

Future Residents (of the development)
As the site is existing and already has lighting around the perimeter of the building the effects on
the future residents will be minimal.

MITIGATION MEASURES
9.1 Operation
The general design principles that have been incorporated into the Lighting Strategy in order to
mitigate adverse effects of obtrusive light have included:
• Orientation – lighting units have been chosen so that no light is released above the
horizontal. This involves use of a suitable luminaire, positioned at a height that is great
enough to allow light to be directed downwards.
• Placement – lighting should be located away from sensitive receptors wherever possible.
• Reflectance – any high intensity lighting should be installed onto buildings or columns and
directed to the area where the light is required, rather than facing a building façade which
may be reflective and result in sky glow.
As set out in Table 5-1 the Lighting Strategy presently meets the required pre-curfew limitations of
ILP Environmental Zone E3.
Achieving levels within the acceptable limits for ILP Environmental Zone E3 will maintain the ‘low
district brightness’ for the Application Site and thus minimising the possible effects of obtrusive light.

CONCLUSION
The lighting assessment has identified the baseline conditions of the current Application Site
including details of screening, topography, vegetation, buildings/structures and potential sources of
existing artificial lighting. In the context of the existing lighting conditions, it was established that as
the Application Site is located within a suburban area it can be categorised within ILP Environmental
Zone E3.
Potential sensitive receptors that may be affected by obtrusive light have been identified and include
existing and new residents; ecological receptors; and users of road etc.
The Lighting Strategy for the Warehouse site has sought to minimise levels of lighting through
designing to the relevant British Standard; minimise the effects of obtrusive light on existing and
future sensitive receptors; and meet the obtrusive light limitation for exterior lighting specified for ILP
Environmental Zone E3.
The lighting assessment has identified limited effects of obtrusive light on sensitive receptors.
Based on this assessment and subject to the incorporation of the recommendations set out in this
report, it is considered that obtrusive lighting from the proposed Lighting Strategy does not pose a
constraint to the proposed development.

(1) Upward Light Ratio Some lighting schemes will require the deliberate and careful use of
upward light – e.g. ground recessed luminaires, ground mounted
floodlights, festive lighting – to which these limits cannot apply. However,
care should always be taken to minimise any upward waste light by the
proper application of suitably directional luminaires and light controlling
attachments.

(2) Light Intrusion (into
Windows)
These values are suggested maxima and need to take account of
existing light intrusion at the point of measurement. In the case of road
lighting on public highways where building facades are adjacent to the lit
highway, these levels may not be obtainable. In such cases where a
specific complaint has been received, the Highway Authority should
endeavour to reduce the light intrusion into the window down to the post
curfew value by fitting a shield, replacing the luminaire, or by varying the
lighting level.
(3) Luminaire Intensity This applies to each source in the potentially obtrusive direction, outside
of the area being lit. The figures given are for general guidance only and
for some sports lighting applications with limited mounting heights, may
be difficult to achieve.
(4) Building Luminance This should be limited to avoid over lighting and related to the general
district brightness. In this reference building luminance is applicable to
buildings directly illuminated as a night-time feature as against the
illumination of a building caused by spill light from adjacent luminaires or
luminaires fixed to the building but used to light an adjacent area.
