Lighting case study
Swimming pool

Lighting Controls:

Significant potential for additional energy savings via lighting controls was available. Lights did not need to be running at 100% power because:

1. High lux levels were only required during competitions
2. During the day, natural light contribution was high, through a fully glazed wall
   
   

The Challenge:

ARC Leisure wanted to benefit from dimmable lights but needed a non-invasive control solution; the installation had to be carried out during the night during a brief 2 week window, and controls were not to be positioned pool-side. Installation of new low voltage control lines was not an option.

The Solution:

Kellwood Lighting provided a cost-effective wireless control package. A wireless mesh network ensured that all lights could be individually controlled or grouped. A wireless six-button scene switch was located outside the pool area, programmed to achieve different desired lux levels.

Finally, photocells could assess ambient lux levels, and regulate the light output accordingly. This was simple to install commission, and maintain, ensuring the client's brief was met.

Final Controls Solution:

• 43No. wireless nodes, controlling individual lights
• Programmed scenes from 500lux to OFF (in 100lux steps) via a 6-button wireless switch
• Daylight Harvesting - lights automatically dimming when ambient light contribution through the partially glazed walls is high (via photocells c/w wireless nodes)
• Remote application via tablet and 4G data connection
• A non-invasive solution - installed in one week, without any alterations to wiring
