E-street project report

EXCECUTIVE SUMMARY
The Project Report will give an introduction into the work of the E-Street Project. The project is
supported by the EU-IEE Save programme and has been carried out for the period of 30 months from
January 2006 until July 2008.
The partners, 13 organisations from 12 European countries are all presently involved with street lighting.
The outstanding expertise of the team was utilized into a very successful work performed all over
Europe.

Intelligent street lighting

The phrase Intelligent street lighting includes a total system with dimmable luminaires, advanced
lighting control solutions, communication systems and administrative tools. The solution focuses on low
energy consumption and high functional standard. It also, in most contexts, automatically declines the
maintenance costs for the operator in combination with increased safety for the street user.
In most cases Intelligent street lighting in its practical design is identical to Adaptive lighting . Anyway
one should distinguish between the two descriptions, remembering that Adaptive lighting only describes
the performance of the light on the road, while Intelligent streetlighting also includes the more
operational elements, back office software solutions and both energy and labour cost saving potentials.
Streets or roads equipped with such a solution will dynamically adapt the street lighting performance
according to the actual needs for the given period/time of the road. Typically it will lead to lowered
lumen output from the lamp during good conditions, when low traffic volumes or low average speed
appears in combination with non-foggy weather. This will also be the case if the surface is covered with
snow.

Market potential

The market for intelligent streelighting is huge. Based on the existing installations within Europe, the
project have identified an annual saving potential of 38 TWh electricity by retrofit old installations with
adaptive lighting. 38 TWh saved electricity represents as much as 63.7 % of present annual consumption
for streetlighting purposes within the community.

Outcome Highlights

The main outcome of the project may be highlighted into four main results as outlined below. Hopefully,
and in line with the strategy of the project, the really MAIN result will only be seen in the future, when
the market for intelligent streetlighting starts to increase dramatically. Then the expert input to the
industry, the developed standards, the financial schemes and marketing effort will be judged as
valuable contribution to the development within the field.

Financing schemes and models

The energy performance contract (EPC) model is modified for streelighting purposes. A calculation
model is developed. Based on previous experience from other TPF markets, the Berliner Energie Agentur
was subcontracted for the work. Together with Investitionsbank Schleswig-Holstein, who has a lot of
experience with the financing of energy efficient investments in their region, the project developed an
adapted contract model for public lighting based on intelligent streetlight solutions.
The contract model incorporates the baseline and relevant contract model into a complete package of
turn key solution for the investor. Beside the contract the WP also developed a calculation model for
refurbishment projects. The model calculates both the investment, the cost savings and financing costs
incurred and outlines the cash flow analysis of the tentative project.

CONCLUSIONS

The project activities have been performed for more then 30 months. Over this period, all the
partners have been active involved in studying, monitoring, writing and giving presentations
about intelligent streetlighting all over Europe.
This report tries to summarise over a limited number of pages the most distinguish outcome of
this work. The project is supported by EU-programme IEE according to contract no IEE/05-157.
