Kungsleden, Sweden

Overview:

Kungsleden switch 3 more car parks to LED

PROJECT: Reducing energy consumption by 20% by 2020

The Brief-

The property owner, Kungsleden are upgrading another 3 garages in the three properties Vipan, Verkmastaren and Varblomman, to LED lighting. Kungsleden has set a long-term goal of reducing energy consumption by 20% by 2020.

The Solution-

In all 3 parking garages, the LumiROD 414 was installed. This LED light is a daylight white and highly energy efficient luminaire, providing 167 lumens per watt. A daylight white variant of 5300 kelvin was used to increase the visibility of the garage and create a fresher living environment.

The LumiROD 414 is fully dimmable between 0-100%. The luminaire is equipped with a built-in light & motion sensor.
To increase savings where possible and reduce energy usage we chose to use a built0in microwave sensor for presence control. The lumiaires are configured to use 10% power (about 4 watts) is motion is not detected. When motion is detected, they turn on to full power for ten minutes. Motion sensor settings can be easily changed in place (after installation) with a remote control.

The LumiROD 414 has a high protection class (IP66) with a smooth upper side that is suitable for parking garages or other dirty environments. This means that the luminaire lights longer and clearer with minimal or no maintenance requirements.

Results compared to the previous lighting:

– 33% fewer luminaires in the garage

– 88% lower annual energy costs

– Average illuminance of about 100 lux (compared to 40 lux before)

– Visibility has improved since the daylight white light makes the colours and movements easier to perceive by the eye.

– 88% lower annual CO2

– 52% lower total cost over 10 years
