SJB Floodlighting Limited The Robins Birches Walk Galleywood Chelmsford Essex CM2 8TZ

Tel 01245 287911 Contact Brian Blunden Email [email protected]

NICEIC No. 501167/000 – Approved Contractor (Street and Exterior Lighting Installations & Maintenance of Electrical Installations) 1.1 This document sets out the design of floodlighting for the proposed Two Five-A-

Side Pitches, Triple Tennis/MUGA Area and All Weather 7-A-Side Pitch.

Floodlighting of the Pitches detailed are generally in accordance with the Guidance Document produced by Sport England, in conjunction with the Sports and Play Contractors Association – with an illumination level of 200 LUX for recreational use.

Institution of Lighting Engineers (ILE) guidance notes for the Reduction of Obtrusive Light, 2005

1.2 Lighting calculation have been processed using accredited computer software

design and supplied by Philips Lighting (CalcuLux Area 7.5.0)

1.3 The scheme has been designed to minimise as far as possible unacceptable light intrusion beyond the boundary of the site.

1.4 The following every day illuminance level may help to provide a perspective on

the values given in this document.

Moonlight - 0.5 to 1 Lux

Residential Road Lighting - 5 Lux

Commercial Office Lighting - 500 to 1000 Lux

Overcast Day - 5000 Lux

Televised Football - 800 to 1500 Lux

2.0 Existing Lighting and Local Environment in the Vicinity of the New Pitch

2.1 The nearest light source to the new pitch would be the new school, internally lighting

from windows and external security lighting. The surrounding roads have street lights. 2.2 The area has not specifically been designated, however we have used as a guide an

area of low ambient light and would fit in to the definition in the ILE Guide (copy attached) as an Environment area E2 ‘Area of Low District Brightness’

2.3 The following obtrusive light limitations would then apply:

Sky Glow (upward wasted light ratio) - 2.5%

Lighting into windows before curfew - 5 Lux

Source intensity before curfew - 7.5 kilo-candelas (7500cd)

The angle of peak intensity from each floodlight should be kept below 700

The front glazed panel of the floodlight should be kept as near horizontal as possible


Page 6

3.0 Extent of Illumination Requirements 3.1 The extent of illumination required is determined by the :-

‘Floodlighting of the All Weather and Multi Use Games Area (MUGA’s) would be in accordance with the details in the ‘Guidance Document produced by Sport England, in conjunction with the Sports and Play Contractors Association’ for a recreation level of light.

3.2 MUGA

Minimum maintained average illuminance on horizontal plane to the principle Play Area of the pitch - 200 Lux

Uniformity ratio (minimum to average illuminance) - 0.60

Maintenance factor 0.80

Glare Rating < 50

Colour rendering factor - ≥ 65

Colour temperature (K) - ≥ 4000 3.2 All Weather (5-A-Side & 7-A-Side Pitches)

Minimum maintained average illuminance on horizontal plane to the principle Play Area of the Football pitches - 200 Lux

Uniformity ratio (minimum to average illuminance - 0.60

4.0 Description of the Scheme 4.1 General

All Weather 5-A-Side Pitches The scheme proposed comprises 4 No. Lighting columns, located outside of the perimeter fence of the Pitch. The height of the columns is nominally 10 metres above the court surface, together with 2 No. Columns that serve the adjacent MUGA’s. The columns would carry a total of Eight floodlights (Four per Pitch) to illuminate the pitches as detailed on the attached computer print Ref 9235e. MUGA & All Weather 7-A-Side Pitch The scheme proposed comprises 6 No. Lighting columns, located outside of the perimeter fence of the Pitches. The height of the columns is nominally 10 metres above the court surface. The columns would carry a total of Eight floodlights (Four per Pitch) to illuminate the Pitches as detailed on the attached computer print Ref 9235e.

4.2 Description of the data included in the computer print Ref 9235e.

Page 2/16 is a Table of Contents.

Page 3/16 shows a 3D Project Views indicating the floodlight aiming grids and layout of the Pitch, together with the slope of the surrounding land.

Pages 4/16 & 5/16 detail a Summary of Data used to calculate the results. We would point out that a Maintenance Factor has been used to model the resultant illumination levels throughout the life of the system – this is to comply with the requirements of the Sport England and gives ‘Maintained Values’. It should be noted that all calculation are based on an area without obstruction from trees etc., (worst case situation).

Page 6/16 details the horizontal illuminance level across the MUGA 1 (Triple Tennis/Basketball MUGA) in a graphical table format (maintained Average - 215 Lux, Min/Ave Uniformity 0.61 Min/Ave). Page 7/16 details the horizontal illuminance level across the MUGA 2 (All Weather 7-A-Side Pitch) in a graphical table format (maintained Average - 241 Lux, Min/Ave Uniformity 0.61 Min/Ave). Page 8/16 details the horizontal illuminance level across the 5-A-Side 1 in a graphical table format (maintained Average - 227 Lux, Min/Ave Uniformity 0.69 Min/Ave). Page 9/16 details the horizontal illuminance level across the 5-A-Side 2 in a graphical table format (maintained Average - 239 Lux, Min/Ave Uniformity 0.68 Min/Ave).


Page 8

Page 10/16 details the horizontal illuminance Spillage (footprint) over an extended area with all floodlights illuminated in an ISO contour format at 5 Lux (the Grid of the area includes for the slope of the ground).

Pages 11/16 to 14/16 detail the vertical illuminance over an extended area with all floodlights illuminated when viewed in the major compass directions. The values are shown at 1.5 metres above the ground level (eye level). These contours have been combined and superimposed onto the attached drawing No. 2009-235-03 to show the combined 5 Lux contour.

Page 15/16 details the characteristics of the floodlights proposed.

Page 16/16 details the column positions; floodlight mounting height (Z), aiming points and aiming angles.

4.3 Upward Waste Light Ratio

The proposed floodlight sits in a close to ‘flat glass’ Orientation, (ie the glass is parallel to the ground). Page 5/16 indicates Upward Waste Light Ratio (ULR) for each switching mode as 0.00 this indicates NO direct light is emitted above horizontal. The ILE requirement for an E2 environmental zone should be less than 2.5% – therefore the proposed scheme complies with ILE E2 Requirements.

4.4 Obtrusive Light Calculations Pages 6/16 & 7/16 indicate the maximum source intensity (cd) at the observer positions indicated on Drawing No. 2009-235-03. OB 1 Aa 4558cd (4.558kcd)

OB 2 Bb 1196cd (1.196kcd) OB 3 Cc 5854cd (5.854kcd) OB 4 Dd 6289cd (6.289kcd) The ILE requirement for an E2 environmental zone is that no value should exceed 7500cd (7.5kcd) – therefore the proposed scheme complies with ILE E2 Requirements.

4.4 Mast Height The mast height has been calculated to reduce the potential visual impact to the surrounding area and confirm to the requirement of the afore-mentioned guides from consideration of the angle at which the floodlights are to be aimed.


Page 9

A column height 10metre above the pitches would be used to be within the guidelines and allow the floodlights to be mounted in a close to ‘flat glass’ orientation.

The proposed floodlight has a maximum peak intensity angle of 620. The maximum Tilt angle of the proposed floodlights is ≤690, therefore the glass of the floodlight would be elevated a maximum of 7.50 above parallel with the pitch surface. The is less than the maximum peak intensity angle of 700 stated in the ILE guide - therefore the proposed scheme complies with this requirement of the Standard.

4.5 Masts

Mast would be steel, tapering to the top. The finish would be hot dipped galvanized unpainted. They would incorporate a base compartment housing the floodlight control gear, local electrical isolating and protection equipment. These masts would have a hinged arrangement to facilitate maintenance and lamp changing of the ground. Lowering orientation of the masts would be set-up to suit the fence arrangement of the pitch (ie lowering parallel along the fence). A fix crossarm arrangement would support the floodlights at the top of the masts. Once correctly positioned all floodlights they would be securely clamped to prevent movement. Foundations for the columns would be cast in-situ concrete of adequate mass and formulation to suit the ground conditions and loads imposed by the column and floodlights under design wind conditions for the location of the site.

4.6 Floodlights

The floodlight selected has been specifically developed by Philips Lighting for this type of application. It embodies very close control of the asymmetric light beam, precise optics for accurate aiming and minimising spill. The calculations have been based on the Philips MVP 507 ‘Optivision’ floodlight using 1 & 2kW MHN-TD (metal halide) lamps in Medium Beam Project as detailed on pages 4/16 & 16/16 of the computer plot 9235e.

4.7 Controls It is envisaged that a timing control be provided to ensure that the floodlights are not used after an agreed time. Switching arrangement would be incorporated to enable each pitch to switched separately.

The nominal values shown in this report are the result of precision calculations, based upon precisely positioned luminaires in a fixed relationship to each other and to the area under examination. In practice the values may vary due to tolerances on luminaires, luminaire positioning, reflection properties and electrical supply.
