As part of reaching its energy saving goals as well as improving the lighting / work environment, Horsens Municipality decided on LED lighting in the entire building including offices, meeting rooms, hallways, toilets etc.
Horsens is a Danish city in east Jutland with a population of approx. 57,000 and a total of 88,000 in the entire Municipality. Right in the middle of Horsens the city hall is located. The city hall was designed by MAA Architects and completed in 1985 with a total of 21,000 square meters.
As part of reaching its energy saving goals as well as improving the lighting / work environment Horsens Municipality decided on LED lighting in the entire building including offices, meeting rooms, hallways, toilets etc.
As part of the architectural building design the existing CFL tube lighting fixtures and acoustic ceiling was custom designed for the city hall to fulfil and follow the contemporary design set by the architects. The odd-size lighting fixtures did not allow the use of standard LED lighting fixtures in all offices, meeting rooms etc. The existing CFL tube fixtures were very energy inefficient both due to it mechanical structure as well as the use of T8 CFL tubes, giving a poor light work environment.
In a high ceiling conference hall CFL bulb lighting fixtures were not able to provide sufficient light for various activities and was difficult to service when CFL bulbs was to be replaced.
EURO Lumex developed a new lighting plan based on a custom designed LED panel under the constraint of fitting into the existing custom made acoustic ceiling. To further improve the work environment the LED panels were supplied with a lumen output increasing the lux level to min. 300 lux at desk height and the CCT was changed from 3000K (CFL tube) to 6000K. More than 1.800 lighting fixtures was replaced with the EURO Lumex custom LED panel.
62 pcs. CFL bulb lighting fixtures in the high-ceiling conference hall were replaced with 32 pcs. dimmable high power LED downlight spots providing a lux level of min. 500 lux at floor level.
There is a calculated reduction of 54% in the energy consumption. The investment including installation have a payback period of 3,9 years, falling well within the warranty period of 5 years.
Increasing the general lux level as well as changing the CCT to 6000K resulted in a significantly improvement of work environment providing less sick leaves and higher productivity.
This project is a golden example of EURO Lumex’s expertise of providing high quality, innovative and project specific solutions resulting in shortest ROI-time, high energy savings as well as improved work environment.
