32 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.

33 PRO-ENVIRONMENT OUTDOOR LIGHTING PROJECT SAVING THE ENVIRONMENT AND THE MONEY The Pro-Environment Outdoor Lighting Project (phase II) was initialised in year 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 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 ( kpl) - The control system is renewed and a new control method is defined - The electricity grid and substations are checked and optimized

34 PRO-ENVIRONMENT OUTDOOR LIGHTING PROJECT Street lights were changed into yellow SON in White light is used only in the City centre, new housing fair area Äijälänranta, shopping districts, playgrounds, parks and some pedestrian paths. OLD SITUATION 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! NEW SITUATION 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 (installed and equipped with a lamp).

36 PRO-ENVIRONMENT OUTDOOR LIGHTING PROJECT KUOKKALA BRIDGE NOW NEW SITUATION

37 PRO-ENVIRONMENT OUTDOOR LIGHTING PROJECT KUOKKALA BRIDGE BEFORE KUOKKALA BRIDGE NOW 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.

39 PRO-ENVIRONMENT OUTDOOR LIGHTING PROJECT 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 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:

40 PRO-ENVIRONMENT OUTDOOR LIGHTING PROJECT Energy consumption MWh/a MWh/a Savings are now about 25,1 % Burning hours From to 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 h.

41 PRO-ENVIRONMENT OUTDOOR LIGHTING PROJECT 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 and the energy bill with

42 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.

43 WHAT EVER THE METHOD IS, ACT NOW! THERE S NO REASON TO WAIT.

47 GUERRILLA LIGHTING EVENT Pictures present an example from Jyväskylä (2012), daytime, nighttime and Guerrilla illumination. City of Light Jyväskylä (FIN) Annukka Larsen, 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.
