LED Lighting Case Study – Tillery Valley Foods.
Lighting represents around 40% of a building’s total energy consumption – therefore more efficient lighting is a simple and effective way to reduce energy use.
Tillary Valley Foods is one of the country’s leading producers of ready hospital meals. It does so in buildings which were relatively poorly lit with existing CFL lights. Cleanliness is fundamental to its operations and it is frequently audited to ensure bacterial counts are low. Upgrading the lighting allowed for (a) an improvement to the ambient light in the factory making operations easier and (b) reduction in running costs. The lighting was run 24/7 and never switched off.
LED lighting can deliver energy savings of up to 75% against fluorescent lighting, and over 80% against incandescent bulbs. With its added flexibility in terms of shape and colour dynamics, as well as its outstanding efficiency and long life, all of these traits combine to make it the lighting standard of the future.
Tillery Valley Foods is a large food production site in Wales and is the leading provider of chilled and frozen prepared meals for the healthcare, education, local authority and food service markets.
The site is 12,275m2 in size and operates 156 hours per week, 52 weeks per year. It was therefore important to consider both its energy use and environmental impact. Lighting is a major contributor to this, given the constant and continued operation of the site.
Power on Demand Ltd engaged with the site team to assess the most appropriate solution, including:
- Full site survey of existing lighting provision.
- Engagement with the site team understand operational activities and assess needs.
- Calculation of a business case covering capital cost, return on investment, finance options and carbon/energy savings.
- Installation programme timescales.
From our assessment, our team provided a full robust business case for the LED replacement programme. The site would benefit from:
- More than 500,000 kWh saved in electricity annually.
- Over £50,000 reduction in energy savings in Year 1 alone, and over £290,000 savings over five years.
- Reduction of the site’s carbon footprint by over 290 tonnes.
The full installation of the project took four weeks to complete, with our team managing the process in a full turnkey solution, working around the existing operation without disruption, enabling the site to operate in ‘business as usual’.
The Difference in Lighting Areas
As well as being significantly more efficient than ‘standard’ lighting, LED lights provide a better quality of light. LED provides a sharper lighting environment and brighter working areas, whilst also significantly reducing energy costs.
Chevron Canary Wharf
The project amounted to over 1,600 fittings on two floors. The building is in use 24/7 sporadically. Power on Demand Ltd engaged with Chevron and Sodexo to provide the most appropriate lighting solution. Chevron’s key requirements were:
