Weblight provided relamps and maintenance across more than 700 Sainsbury’s stores throughout the UK. This included planned preventative maintenance visits to ensure the functionality of all lighting for the duration of the contract. In addition, we also relamped car parks and provided a warranty on all materials and labour, to meet with Sainsbury’s rigid and market-leading specifications.
Lighting is a key part of any pub – and none more so than at Marston’s Brewery locations across the UK, where lights can be on 16 and a half hours a day, seven days a week. By installing LED lights front of house, we helped save the client 83% in terms of energy use and cut the company’s carbon emissions by an enormous 80%. But we weren’t finished there. By conducting our initial survey, we could tell Marston’s how much more they’d save by upgrading to LED in back of house and externally too. Currently, we are several months into an ongoing project that will transform 260 pub locations a year.
The Royal Mail had been investigating a range of initiatives to reduce their carbon footprint across the business spectrum, with electrical usage from lighting being one of their major areas of consumption. They asked Weblight to help them find an energy efficient, flexible solution for their Yorkshire Distribution Centre.
The site is occupied permanently, however, functions and activities migrate to different areas during the day dependent upon the tasks being undertaken. These work patterns do not require the lights to be on 24/7 and at full output, but to be flexible in line with work patterns.
The original lighting scheme consisted of 400w luminaires mounted at 11m to service the racking areas and manual activity without any lighting controls, providing blanket lighting levels. With the single lamp installation, when individual lamps failed, uniformity and light levels were compromised.
Following discussion with Royal Mail and a trial installation, Weblight recommended replacing all of the high bays with a 6 x 49w T5 luminaire. A lighting control system capturing movement and daylight contribution was aligned to the new fitting. Both aspects were key requirements as activity and movement migrate around the facility, whilst the building benefits from significant levels of natural daylight.
The new fixture provides a LOR of 90% and ensures all available light is used effectively to illuminate the working environment. The new fixtures have replaced the original high bays on a simple point for point basis, minimising installation costs and site disruption. The lighting controls also allow light levels to be set to a maximum and minimum level to ensure compliance to the activity being undertaken.
Analysis following the completion of the project has shown that the Royal Mail has recorded a 56% reduction in energy and 457 tonne reduction of CO2 per year.
We expect Royal Mail to benefit from payback within 2.5 years.
Port of Tilbury
We installed and replaced lighting in the Rubb sheds and lorry bays at the Port of Tilbury – saving our client an average of £37,000 per annum of energy costs, reducing their electrical load by nearly 50%.
King’s College Hospital
The service road around Kings College Hospital is used at all times, particularly by ambulances responding to emergencies – therefore the road needs to be lit at all times. Weblight replaced the existing lighting with LEDs, reducing their energy usage by 76%, with a CO² reduction of 70%. A new emergency lighting system was also installed in one of the hospital’s wings, which is now managed through a preventative maintenance contract by us.
