4 1. Executive Summary 1.1 Background Fonterra Ltd (Fonterra) is applying for consent to expand its Studholme Manufacturing Plant located at Studholme, Canterbury. The development would see the addition of two new 30 tonnes/hour dryers, boilers, additional dry goods storage, roading and tanker parking and associated ancillary facilities. Fonterra has requested Aurecon New Zealand Ltd (Aurecon) to design the lighting for the proposed development, and provide technical documentation to form part of the resource consent application. This report details the proposed lighting design for the site. The report covers the design compliance for the following areas of lighting Site access at the intersection of State Highway 1 and Molloys Road, Proposed railway siding, and, Internal lighting of the site roads & pedestrian walkways. Relevant lighting standards applied include those of the NZTA, AS/NZS 4282, AS/NZS , Clause F6 of the New Zealand Building Code and the KiwiRail Standards. 1.2 Site access (SH1/Molloys Road) Multiple lighting simulations in the AGI32 software were performed in order to determine the design compliance of the lighting at the proposed site access at the intersection of State Highway 1 and Molloys Road. The lighting requirements of NZTA for the SH1 intersection of a maximum spill light of 10 lux 3m inside the property boundary are met. 1.3 Railway siding An average horizontal lux of 3 and uniformity of 0.25 as required under KiwiRail standards for rail sidings is met. Light spill from the siding area is less than 3 lux at the boundary which is within the limits of AS/NZS 4282 for residential/commercial areas (25 lux at 5m beyond the boundary). 1.4 Internal lighting Fonterra requirements for lighting of the internal roads & pedestrian walkways are met. Light spill from the site is less than 3 lux at the property boundary which is within the limits of AS/NZS 4282 for residential/commercial areas (25 lux at 5m beyond the boundary). 1.5 Light spill Light spill from the site at the boundary is less 3 lux. This is significantly less than AS/NZS4282 limits of 25 lux at 5m beyond the boundary for residential/commercial areas. Based on the information above it can be concluded that the effects of light spill on neighbouring properties can be considered no more than minor.

6 3. State Highway 1 Intersection Modification 3.1 General Design The proposed configuration of the proposed State Highway 1, Molloys Road and Site Access road and intersection is a channelized four-way intersection. The following design assumptions were made whilst designing the lighting for the intersection: 1. An intersection of three roads exists. 2. Channelization of converging/ diverging traffic streams is present. 3. Radii of less than 100m exists. 4. State Highway 1 is a motorway and therefore classified as V3 as per AS/NZ The CREE LEDWAY series E T3M 120 LED 525mA 4300k was selected a as the primary luminaire and complies with the minimum luminaire requirements as specified by AS/NZ The road surface is assumed to be NZR2 with a surface reflection value of (Qo) of According to AS/NZ clause all intersections with channelization require an illuminance based lighting design. The design parameters for a V3 carriageway are highlighted in red in Table 1 AS/NZS and are shown below: Table 1. Table 2.2 from AS/NZS Table 2. AGI 32 Calculation summary of the lighting levels at the intersection Above is a table summarizing the results of the road lighting simulation modelled in AGI32. As can be seen the values for road surface satisfy the requirements of Table 2.2. above of AS/NZS The average value is higher than the minimum value of 7.5 required for point horizontal illuminance. The horizontal illuminance uniformity (Ue1) is 5.66 which is less than 8 and therefore satisfies the requirements of AS Revision C Page 3

7 All the surrounding verges have Eph values greater than 3.5 and Ue1 values less than 8 therefore satisfying the lighting requirement for verges of AS Design Assumption 1: Road Intersection The configuration of State Highway 1, Molloys Road and Site Access road and is an intersection with channelization. The illuminance based requirements are also specified by AS/NZS and are shown below: These design rules are best illustrated by a diagram also from AS/NZS and is shown below: Revision C Page 4

8 Figure 2: figure 3.8 from AS/NZS As can be seen in figure 2 (above), the dark grey shaded area represents values of Eph and Uei taken from table 2.2. For V3 roads, these values are 7.5 and 8 respectively. The light great area represents 0.5 x Eph, which is Figure 3: Road lighting 10m demarcation lines from the curve Above is a diagram taken from the lighting design with isolines and LPD points satisfying the requirements of AS/NZ discussed above. Revision C Page 5

9 3.3 Design Assumption 2: Channelization AS/NZ clause requires an illuminance based design for sections of road with channelization: There are separate requirements for converging and diverging traffic streams: Again these lighting requirements are best visualized by the diagram representing the above taken from AS/NZ Revision C Page 6

10 Figure 4: AS/NZ channelization road lighting requirements The convergence and divergence areas of the intersection are shown below: Figure 5: Convergence and divergence zones of the SH1 Intersection As can be seen in figure 4, the dark grey shaded area represents values of Eph and Uei taken from table 2.2. For V3 roads, these values are 7.5 and 8 respectively. The light great area represents 0.5 x Eph, again this is Revision C Page 7

11 Figure 6: Example showing a divergence zone in the AGI 32 model Above is an example diagram taken from the lighting design with isolines and lighting LPD points meeting the design requirements of Eph and Uei discussed above highlighting a modelled area of convergence for street lighting. 3.4 Design Assumption 3: radii For a road with curvature radius less than 100m, an illuminance based calculation shall be performed as per AS/NZ clause a The illuminance requirements for radii less than 100m are also specified by AS/NZ clause and are shown below: Revision C Page 8

12 and is illustrated by the following figure 7: Figure 7: Revision C Page 9

13 As can be seen below, all of the intersecting channelized roads have radii less than 100m. As can be seen in figure 7, the dark grey shaded area represents values of Eph and Uei taken from table 2.2. For V3 roads, these values are 7.5 and 8 respectively. The light great area represents 0.5 x Eph, again this is Below is a diagram taken from the lighting design with isolines and lighting LPD points meeting the design requirements of Eph and Uei discussed above for street curves with radii of less than 100m. Note that on the diagram the blue lines indicate the end of curve segment to be modelled. Figure 8: Lighting curve segments less than 100m radius Revision C Page 10

14 3.5 Spill lighting The following measure shall be undertaken to control spill lighting during the detailed design phase: Luminaires shall be off the approved NZTA M30 list. The mounting height shall be limited to 10m. The lighting columns shall meet NZTA M26. Where lighting spillage occurs, the tilt angle shall be adjusted accordingly, to a maximum of 10. Revision C Page 11

15 4. Railway Siding 4.1 General Design Luminaires used included: - Thorn Area1 150W HST-MF L ANT A/S - Thorn Area 2 250W HST-MF L ANT A/S6 The result is that the average light level off lux is much higher than the minimum required by KiwiRail for a siding. As is demonstrated in the tables below: Below is the table taken from the AGI32 lighting simulation. Note that the Max value, is much higher than that of the recommended. Table 3. AGI 32 Calculation summary for the Kiwirail Siding.. However since Fonterra requires the rail and pavement load out areas next to the sidings to be well lit, the difference in lighting levels between that of the loading area and that of the KiwiRail siding corridor would be significant, noticeable and not provide uniform lighting between the loading and rail areas. It is therefore Aurecon s recommendation to maintain a high lux level over the rail corridor. Revision C Page 12

16 4.2 Spill Lighting A major design concern was that the new lighting for the loading area may cause obtrusive lighting effects to any neighbouring properties. Since the proposed site location is not near any residential properties (the Bleeker dwelling is approximately 470m from the loading area), as per NZ standards, lighting spillage effects are not a design concern. However, Aurecon produced simulations to model obtrusive effects on the neighbouring surrounds. The simulation determined the average lux level in the vertical plane 5m away from the property border. The result was 5 lux. AS4282 Table 2.2: Control of the obtrusive effects of outdoor lighting at 5m away from the border property, requires 25 lux or below for residential/commercial areas. Therefore the proposed railway siding lighting layout complies with AS/NZ standards. Figure 9: KiwiRail siding light spillage model. Revision C Page 13

17 5. Site Internal Lighting 5.1 Service Dryer Towers The Service Dryer Towers are not to be lit above 12m. An AGI32 simulation was performed to model the impact of the surrounding road lighting on the towers. The following results were observed. Figure 10: Light levels of the dryer towers. At a height of 10 m, the lux level is 13.3 as a result of the surrounding road lighting. Higher than 10 m the lux level quickly drops off to 1.3 lux. For reference 3 lux is the brightness of the moon on a clear night. Therefore these lighting levels are acceptable. Revision C Page 14

18 5.1 External Staircases The external stair cases of the Darfield site were used as reference for the design. Figure 11: External staircases of the Darfield site No lighting standards exist for external staircases. However as a guide, the following standards were used. Table 4. Lighting standards used to determine a suitable lux level for the external staircases. Standard AS/NZ :2005: Table 2.7 P6: Values of light technical parameters for public activity areas AS/NZ :2008: Table D1 : Recommendations for circulation spaces and other areas: Stairs (internal) New Zealand Building Code, Clause F6 Visibility in Escape Routes Third Edition Average Horizontal illuminance (Eh) 21 lux 80 lux (internal building lighting) 1 lux (at every change in level in an escape route) An AGI 32 simulation was performed on a typical segment of the staircase using Thorn Leopard 1250 LED2 E3 Ops. Thorn Leopards have an emergency light function. The following Results were observed. Revision C Page 15

19 Figure 12: AGI32 Typical of the Studholme site external staircase. As can be observed in figure 12, the average light levels at the staircase landings are 39 lux and lux respectively. Furthermore, the light level drops off on the stairs themselves with 22.7, and 7.07 lux. These light levels are above the minimum requirement for category P lighting of 21 lux, with the exception of the individual stairs which was expected. In addition the light level of around 32 lux is much higher than the required level in an emergency of 1 lux, which is the primary function of the staircases and thus is an acceptable lighting solution. These lights will be controlled via movement sensors so will only activate when the stairs are in use, which at night would most likely be an emergency situation. 5.2 Internal Roads & Pedestrian Walkways Spill lighting In order to minimize light pollution and glare, with few exceptions, the majority of the luminaires were modelled and shall be installed with a tilt angle of 0. In addition the luminaires were selected with optics that minimize spill lighting. Finally, care was taken in design to orient the luminaire faces themselves away from areas where spill lighting might be an issue The effects of lighting in the tanker parking, truck wash and milk reception areas was modelled to determine the overall effects of the lighting on nearby State Highway 1. The tree line in front of the tanker parking, truck wash and milk reception areas was set at a height of 7m. The effect of the tree line completely eliminates the spill lighting onto State Highway 1. This is shown in figure 13 below. Revision C Page 16

20 Figure 13: Note the 3 lux isoline does not exceed the tree line. Eliminating the spill lighting from the adjacent areas onto State Highway 1. At no point on the site does the road & pedestrian lighting leave the site boundary at a lighting level higher than 3 lux. For reference 3 lux is the brightness of the moon on a clear night. Please refer to the drawing set sheet 103 through to sheet 116 which confirms the 3 lux requirement. The green isolines on the drawing set represent 3 lux. Figure 14: Sample from the AGI32 road lighting simulation depicting the sites northern boundary. Note the purple line, the site boundary, is a distance from the green Isoline, which represents the 3 lux level and thus spill lighting is averted in all cases. Revision C Page 17
