1.0 INTRODUCTION
This external lighting environmental impact assessment is a desk top exercise to establish the baseline conditions and the likely impact to the surrounding environment of the proposed lighting at the Rushden Site proposed by Monoworld
2.0 LEGAL REQUIREMENTS
This section summarises government policy on the environment with respect to external lighting.
2.1 Statutory Documents
The research paper ‘clean neighbourhoods and environment bill’, bill 11 of 2004-05 suggests under Town and County Planning (assessment of environmental effects) Regulations 1988, developers should submit an assessment of the impact proposed external lighting will have on the environment. While not specifically requiring external lighting schemes to be submitted for approval it does suggest planning authorities have the right to request such information as part of the approval process.
“The Clean Neighbourhoods and Environment Act 2005 has made light pollution a statutory nuisance under the Environmental Protection Act 1990, which came into force on 6th April 2006.”(1)Section 79 of the Environmental Protection Act 1990 (c43) is amended as follows: "artificial light emitted from premises so as to be prejudicial to health or a nuisance." Although this specific act refers to artificial light emitted from a premises it is good practice to ensure any newly installed external street lighting does not emit light on property frontages. Nor should any new installation produce excessive upward light (know as light pollution) or be installed so as to ‘over light’ any street in relation to the external street lighting requirements detailed in the British and European lighting standards.
No prescriptive limits or rules are set for such assessments, but the following guidance documents have been referred to while compiling this assessment and in producing the external street lighting design for this specific project:
- British and European Standards for External Street lighting –
BS5489:2013 - British and European Standards for the lighting out outdoor work
places – BS EN 12464: 2014 - Guidance notes for the reduction of obtrusive light – The Institute of
Lighting Professionals (ILP). - Environmental considerations for exterior lighting – Chartered Institute of
Building Services Engineers (CIBSE).
- Outdoor Environment. Lighting guide 6 – CIBSE.

3.0 SITE LOCATION
The proposed site location Rushden Site, Monoworld:-

4.0 BASELINE CONDITIONS
The following describes the site in relation to existing sources of lighting. Sensitive receptors to light are identified. A review of areas and features of the landscape are also described. The proposed development at the Rushden Site for Monoworld will require an infill lighting system. Using table 12.1 below, it would indicate that the area would be classified as E2 Low District Brightness Areas. Table 12.1: Obtrusive Light Limitations for Exterior Lighting Installations Guidelines and threshold values for the environmental zones published by the ILP provides a guideline on technical limits Notes to table: UWLR (Upward Light Ratio) is the maximum permitted percentage of luminaire flux that goes directly into the sky; Ev is Vertical illuminance in Lux; I is Light Intensity in Candelas; L is Luminance in Candelas per square metre.
5.0 PROPOSED LIGHTING
The proposed lighting scheme will ensure that the neighbouring residences do not have light spillage onto their property as that would be deemed to be unacceptable in line with current guidelines. It is proposed that the lighting impact can be minimised by using accepted methods of lighting control, essentially limiting illuminance and controlling light spill. It is proposed that the external lighting shall be installed on an 8m column. There will also be the requirement for some building mounted LEDs. Generally lighting shall be selected to provide safety and security without polluting the boundary site residents. All luminaires are to have electronic control gear. The lamps specified for this lighting scheme are 15 klm LEDs, these are of a white light source to similarly match what is currently installed All new lighting has been designed in accordance with BS EN 12464: 2014, with the lighting class shown below having been agreed with Monoworld for the type of usage of the site.

Working Area (5.7.1) – Agreed with client Eave = 20 Lux Uo = 0.25 Within the lighting calculations and detailed lighting drawing (MMA12963-001) the spill lighting from the site has been shown using a 1 Lux contour line from the site. This is in accordance with the 1 Lux minimum levels through windows for an environmental zone E2 taken from the ILP obtrusive lighting report: 2011. Should the proposed fittings be assessed as intrusive, it would be possible to fit a rear shields to the WRTL Luma LED unit, however it would need to be a generic shield rather than a manufacturer specific unit. For the flood lighting units a lantern inclination of 60 degrees has been used within the calculation, as it appears the existing floods use a 60 degrees tilt. The proposed WRTL Luma LEDs use a 5 degree lantern inclination and achieve a G4 glare rating. G4 would be deemed as excellent in terms of reducing glare and comparable with what we would expect to see on a trunk road lighting scheme. A flood light would omit far more glare than the units we have specified. Within this design we have only included the proposed forecourt area of the new building and used the existing lighting as contribution only. We have not considered the remainder of the site. This is the area requested by Monoworld. An image of the existing flood lighting unit has been sent to the manufacturer. They have then advised us of the specification currently installed. Monoworld will need to confirm this is correct and matches what is already installed. The manufacturer has stated the existing flood lights are 250w HQI with a colour temperature of 4000k. The match this we have specified neutral white LEDs which are also 4000k colour temperature so the white light colour will match on site. Below is an image of the unit proposed (available side entry and post top): -

6.0 CONCLUSION
Desk top assessments on the proposed site and development indicate (with respect to identified sensitive receptors) that overall surrounding light pollution levels will not be significantly influenced by the proposed development. It is proposed that the lighting impact can be minimised using accepted methods of lighting control, essentially limiting illuminance and controlling light spill. These accepted methods have all been adopted within the proposed lighting design to keep the overall impact of the lighting to a minimum. Due to the specification of the equipments the proposed lighting system with be very energy efficient so the drain on natural resources will also be kept to a minimum. In summary it is our considered opinion that the proposed development will not have any significant negative impact on the immediate environment with respect to lighting pollution or energy usage and that all sensible steps have been taken within the design stage of this lighting scheme to keep the impact to the environment to a minimum.
