C2 SmartPlay Muuratsalo


Muuratsalo leisure sport field lighting control

The Muuratsalo leisure sport field in Jyväskylä was originally illuminated with four 400 W HQL floodlights placed on two different masts. The annual energy consumption of field lighting was 3699 kWh.

The lighting was improved by installing four masts on the field, each with two 252 W LED floodlights. The lighting was directed to brighten only when necessary with C2 SmartPlay solution, i.e. in practice when the user brightens the field lights when entering the field by pressing a push button. At other times, the lighting is on at 10% lighting power.

When the lighting was controlled to brighten only when there were users in the field, the annual energy consumption for lighting in the field was reduced by 90% from 3692 kWh to 368 kWh.
