THE CHALLENGE

The primary aims of the new lighting scheme were to improve lighting levels and minimise energy usage, through the use of Smart controls, while providing a safe and comfortable environment for the public and staff.

THE SOLUTION

Thorlux Lighting proposed a new installation that would combine the necessary energy savings with an improved quality of lighting throughout the building. By replacing the existing T8, T12 and compact fluorescent luminaires with energy efficient LED luminaires the number of luminaires required was reduced by 18% from 4,266 to 3,504. The addition of Smart energy saving controls also resulted in significant energy savings; the integral Smart sensors monitor ambient light and presence, control output to the correct level, dim and switch when there is sufficient daylight and illuminate only when the area is occupied.

Significant reduction in maintenance costs
