The city realized the great potential of lighting during the Lighting Master plan
process in 1999-2000. These inventions were listed:
There’s was no night-time architecture.
Safe and comfortable cityscape is done by illuminating the space.
Road lighting techniques are not valid in the city centre.
Luminaire glare should be avoided.
Darkness is a possibility, not a problem!

City of Light -project is highly appreciated by the public. Urban Lighting Research and interview survey in 2009:
71 % I’m proud of my home town because they invest on good lighting. 90 % I like when architecture, art, bridges, trees, etc. are illuminated.
83 % Several illuminations support city imago as a modern and trendy city. 9 % Lighting of the city has gone way too far already.

PRO-ENVIRONMENT OUTDOOR
LIGHTING PROJECT
Aiming at: Saving
40 %
of the energy used by the outdoor
lighting system, to enhance the illumination and cut the
maintenance costs.
Light in the City event in Tartu
May 7th to 9th 2014
SAVING THE ENVIRONMENT AND THE MONEY
The Pro-Environment Outdoor Lighting Project (phase II) was initialised in year 2009. The aim is to save
40 % from the outdoor lighting energy
consumption
.
Concurrently the illumination on the streets is enhanced and the amout of light pollution is decreased.The saving will be
6 000 000 kWh/a
which is equal to yearly energy consumption of 300 family houses. In euros thetotal saving is one million
per year.HOW IS THIS DONE?
- 50% of the old street luminaires are replaced (14 500 kpl)
- The control system is renewed and a new control method is defined - The electricity grid and substations are checked and optimized
Light in the City event in Tartu
May 7th to 9th 2014
Old luminaires used 125W mercury, and were replaced in the end of the 90’s with 110W HPS replacement lamp.
Old luminaires consume 127 % more energy!
Replacing old ones into new non-glary
luminaires with 50W HPS create the biggest saving. Poles are not changed.
The price for a luminaire of this type varies 150-185 € (installed and equipped with a lamp).
PRO-ENVIRONMENT OUTDOOR LIGHTING PROJECT
Street lights were changed into yellow SON in 1998-2002.
White light is used only in the City centre, new housing fair area Äijälänranta, shopping districts, playgrounds, parks and some pedestrian paths.

Light in the City event in Tartu
May 7th to 9th 2014
Kuokkala bridge, built in 1989, is one of the most remarkable landmarks of city of Jyväskylä.
The energy consumption of the pole lighting was high because the old luminaires used 100W sodium (total 200 luminaires) and the illumination level was over the lighting class. Also due to the maintenance problems it was decided to refurbish the lighting.
Luminaires were changed in 09/2013. Replacing old spheres into new luminaires created 76 % saving in energy consumption. Poles were not changed. Sphere has a warm 28 W LED light module inside. Payback time for the installation is 11 years.

CONTROLLING THE LIGHTS
Intelligent lighting control system by C2 Smartlight Ltd. from Jyväskylä.
Switch off/on times are now accurate and the system allows different control methods.
PRO-ENVIRONMENT OUTDOOR LIGHTING PROJECT
Control system by:
Model for controlling
- Summer switch off for 50 days - Accurate switch off/on times - Dimming and partial switch off’s - Some parks switched off for the night
Fully operational in 2013 and visible in the savings after year 2014.
FEEDBACK FROM THE PUBLIC
Light controls was tested in autumn 2010 and the feedback from the public was quite clear: half of the people didn’t notice any change, some people had
noticed the new lighting being non-glary and almost all supported the project’s energy saving aspect. (Phone survey for 852 persons)
Light in the City event in Tartu
May 7th to 9th 2014
Energy consumption
2013 11 344 MWh/a 2005 14 656 MWh/a
Savings are now about 25,1 % Burning hours
From 3 900 to 3 600 h/a with accurate switch off/on times and summer switch off.
Temporary night switch off’s will cut 800 hours more, so in year 2014 lighting is on only for 2 800 h.

May 7th to 9th 2014
FINANCIALLY PROFITABLE PROJECT
- Total cost 5 million €.
- Energy subsidy from the Ministry of Employment and Economy (25-30%). - Pay-back time 5 years (calculatory).
- Pioneer financing model: Project financed with leasing contracts and later on with savings. No need for large fundings.
- Almost a million euros are saved yearly because the maintenance costs have decreased 360 000 € and the energy bill with 600 000 €.
Light in the City event in Tartu
May 7th to 9th 2014
FOR THE SAKE OF THE ENVIRONMENT
- Savings equal to
1665 tons of CO2-emissions
. That equals to driving a car
around the globe 272 times
(if that would make any sense).
- New lighting is more accurately aimed to its target, not towards the night sky.

GUERRILLA LIGHTING EVENT
During the event, a group of people “occupy” the city's streets with powerful, hand-held torches according to a carefully conceived plan. Participants are instructed on their role in the performance, and on the night, they proceed with hand-held lights, colour filters and rush lights to illuminate one site at a time, and only for a moment.
In each case, a horn is sounded and the building briefly illuminated. During that time, the spectacle is photographed and documented, and the pictures provided to the media immediately afterwards.
