Meritor Lighting Upgrade

The Brief

This lighting project was designed using the existing building roof structure to enhance the amount of natural daylight in to the areas as possible with using energy saving, lux sensitive, infra-red detectors to maximise the total kwh savings on the 24 hour operation at the plant. Early signs are pointing that a 65 percent reduction in energy consumption for the lighting which is helping the company reduce its carbon footprint.

What We Did

Firstly the flat roof was cut and fitted with domed panels to let the natural light in, then the lighting busbar was installed through the lengths of the factory a three phase 250 amp version would run from East to West, the tapping off the 250 amp bar was a three phase 32 amp rated busbar.

Running North to South which was supported by catenary wires with the new lights hung off the 32 amp busbar, in effect each section of 32 amp busbar has a light off each phase, and out of every nine lights one is a non-maintained emergency unit, the majority of emergency’s are located over the main gangways and exit points from the building. The lux level sensors integrated in each fitting monitor the light level at each position they cover so if the sun gets brighter the dimmable control gear will ramp the output down to a pre-set level this also save energy. When the dusk or bad weather come the lights will maintain the set lux level seasonally and daily.

The other clever feature of the lighting is the built in infra-red sensors, if there is a set period of inactivity in the area the light will again dim itself down to the pre-set level until movement activates the sensor and it will ramp back up to its operable output, this is a useful feature on this site due to some areas like stores and certain production areas do not operate 24/7 the lights will dim down to a minimum and switch off if no activity for a total saving. The lights use a day white 4000 kelvin colour tube which really has transformed the factory from a dark morbid space to a well-lit highly productive environment to work.
