What have we learnt (early outcomes)

What is BLISS ?

BLISS is a European research & test project to reduce street lighting energy consumption in different

The Key Aims of the BLISS Project

Reduce energy consumption and achieve significant reductions in CO

Evaluate the impact on crime, accident and socio economic acceptability

Foster trans-national collaboration & engagement

Seeking optimum cost / benefit solution

Develop a best practice guide

Qualitative Proposition

Testing Colour RecognitionParticipants were asked to recognise colours on an underground map when standing between two light columns for different lighting.

Testing Facial Recognition

Participants were asked to recognise a photo of the Queen from the opposite side of the road.

Testing Facial Recognition Participants were asked to identify:- 3 demographic categories

- 3 facial expressions - & distinguish features from 4m away

Revised visual acuity tests – Professional groupDeveloped with Eindhoven University for combined colour and facial recognition testing and

including obstacle recognition

Adequate, friendly Consultant

(70W SON lamps)

Very bright on pavement. Very safe

(Stela LED)

Cold. Car park lighting.

Neighbourhood Manager(Stela LED)

Not impressed. Uniformity very poor. Zebra effect. Engineer (60W CPO lamps)

Very good vision. Very safe. Best street so far.

(60W CPO lamps)

Very bright, can see everything. Safe!

(SpeedStar Eco LED)

Outcome is Shared with Pan European Learning

Design Manual is key output

Pilot on small scale point to best solutions

• Peter Kay principle “It’s the future”

• Insights

• Prototype & trialling

• Innovation (in Transforming Services)

• Opportunities to work strategically

• European Funds for co-operation and learning

• Keep it simple

• Human Centred Design


Conclusions

• White light is choice of public

• Same energy use with white light can feel a lot better

• Listening does work

• Can provide lower lighting and people still happier

• Develop strategy to increase satisfaction, reduce carbon


Conclusions

• Significant Street Lighting Improvements

• Significant Energy & Carbon Reductions

• Innovation Compulsory

• The Future isn’t what it used to be

• Changing Services : Changing the World
