I’m proud of my home town because they invest on good lighting.
I like when architecture, art, bridges, trees, etc. are illuminated.

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
PRO-ENVIRONMENT OUTDOOR LIGHTING PROJECT
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 the total 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

Street lights were changed into yellow SON in 1998-2002.
OLD SITUATION
area Äijälänranta, shopping districts, playgrounds, parks and
some pedestrian paths.
NEW SITUATION
Old luminaires used 125W mercury, and were
replaced in the end of the 90’s with 110W HPS
replacement lamp.
Replacing old ones into new non-glary
luminaires with 50W HPS create the biggest
saving. Poles are not changed.
Old luminaires consume 127 % more energy!
The price for a luminaire of this type varies 150185 € (installed and equipped with a lamp).

KUOKKALA BRIDGE BEFORE
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.
KUOKKALA BRIDGE NOW
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.
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)
Control system by:

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.

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 €.

PRO-ENVIRONMENT OUTDOOR LIGHTING PROJECT
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.

Pictures present an example from Jyväskylä (2012),
daytime, nighttime and Guerrilla illumination.
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.
