Scott Safety, a provider of life safety protection products and services, expects to reduce its energy consumption at its Skelmersdale site by 81 per cent with the help of lighting manufacturer MHA Lighting
With thousands of people depending on Scott Safety products to protect them in high risk environments, it was imperative that light output, light quality and uniformity were high quality so as to aid precision working.
With its award-winning low energy luminaires and its ability to design bespoke precision lighting solutions, MHA Lighting was chosen to replace all the existing T5 fluorescent fittings in both Scott Safety’s warehouse and its shop floor.
After trialling various fittings to find the optimal light colour, MHA Lighting’s TiLites were chosen that supplied 80CRI and 4000 kelvin colour temperature. This combination is said to significantly enhance the working environment as well as aid precision working and contribute to a greater feeling of wellbeing among the staff.
The project saw a total of 281 MHA lighting LED luminaires with 23 sensors installed – this included 113 award winning High Bay TiLite 70 fitting (82 watts including ballast) and nine TiLite 30/120 (45 watts including ballast) installed above the shop floor and 46 Oval High Bay 150watt fittings in the warehouse.
This reduced annual lighting energy consumption from 263,907kW/h (annual cost of £26,391) to just 51,730Kw/H. Annual energy bills have therefore been reduced to just £5,173.
Through its low-energy LED Luminaires MHA Lighting was also able to achieve a reduction in CO2 production of 84 per cent in the shop floor area and 64 per cent for the warehouse. This equates to product lifetime CO2 savings of 2,003 tonnes (115 tonnes per year).
Pete Osborne, production engineering and facilities manager for Scott Safety, says: “Lighting is a significant part of us achieving our carbon footprint reduction goals.
“When we set out on this project we wanted to find solutions that improved light quality and also significantly reduced our energy consumption.
“MHA Lighting has been able to offer a solution that ticks these boxes. Not only are we seeing real cost savings on our energy bills but the light colour, output and uniformity is superb and our staff are benefiting from the improved lighting.
“With the integration of various intelligent controls we have made further reductions on our energy usage and given that the units will run maintenance free for seven years we will also decrease our maintenance costs.
“Overall we are delighted with the installation and are now looking at further projects aimed at improving our office lighting.”
At current operating hours the fittings offer a useful lifetime of 16 and 25 years for the shop floor and warehouse respectively. Throughout life they require no maintenance saving Scott Safety a further £51,905 in maintenance costs during product lifetime.
This takes overall lifetime savings for this project to £419,953.
Tom Harrison, MHA Lighting MD, says: “Scott Safety carries out important precision assembly operations, such that the quality of the light – in terms of light uniformity and colour, as well as high levels of light output – is crucial.
“MHA Lighting ran a series of trials at Scott Safety before the customer selected the light colour that it felt provided the ideal working environment for its employees. Another key factor of this installation was the integration of intelligent controls.
“Because of the high quality sky lights in the factory we were able to utilise ambient day light sensors so that during day light hours the fittings will burn at a fraction of their total output thus maximising energy savings further. PIR sensors were also installed in the warehouse.”
