Confidence

• Large scale trials undertaken (Bedford 2,000 pieces)

• Other large scale installations monitored (Lancashire 7,000 pieces)

• Key supply chain partner – open access to performance data

• Defect rate comparisons and early failure data reviews

• Access to R and D Data

Confidence – is it the best solution?

• Evaluation of alternatives :

– Total cost of ownership

– Carbon impact

– Reliability / failure rates

– Sustainability

Central Management & Control System

• 33 transmitter stations

• Long range, high capacity, low

power

• Combined monitoring and control

nodes.

• Group / individual switching and

dimming control

• Flexibility control - 0-10V & DALI

compatible

• Energy harvesting capacity

• Provides active control for

individual lighting columns

• Future proofs the lighting network

• Negates outage detection cycle

• Facilitates variable lighting levels,

trimming, energy metering

• Constant light output (MF

harvesting)

Lighting Case Study

Lighting Case Study

(1) Original Lighting Situation

• Originally 7 Lighting Points

• 7 x 80W MBFU luminaires

• Not to EN standards

• Total Power Consumed

= 658 Watts (e.g. 7 x 94W)

13

(2) Pre-PFI Proposed Design

• S3 / S4 standard

• Maintained lighting levels

• Schreder Sapphire 70W

SON

• 11 lighting points

(4 additional).

• 11 x 79W = 869W

• 32% power increase

(3) Amey PFI Design

• Compliant S4 / S5

• 7 lighting points

• Connection costs minimised

– value engineering

• Total Power = 270W

• 658W – 270W = 388W

saved

• 59% saving vs. original

scheme

14

Energy Comparison

Type Lighting Points Total

Mercury Installation 7 658 W

Sodium Installation 11 869 W

LED Solution 7 270 W

LED Saving = 59% against original MBFU solution.

LED Saving = 69% against typical SON.

* Without Dimming

Outcomes

• Compliant to standards

• Better quality lighting

• Reduced energy and carbon emissions

• Reduced maintenance – outages / detection /

vehicle journeys / replacement lamps and

components

• Reduced total cost of ownership

Conclusions and Summary

• Carbon savings exceed UK Government targets for

2035 In line with Birmingham’s Energy Needs.

• Facilitating Birmingham’s Sustainability Ambitions.

• Helping Birmingham on the journey…to being a

“World Class” Global City….through innovation,

ambition and culture
