An on-site review was carried out by an adviser from Groundwork Cheshire, at the Vector's workshop in Radway Green.
Lighting efficiency drive
As part of the review's findings a number of no-cost or low-cost opportunities were identified to improve lighting efficiency on site.
Ongoing support has since been provided to help the company install new switches and implement a switch labelling policy, so that lighting is only turned on when it is needed.
The improvement project involved splitting the lighting into separate banks, at minimal cost, so that whole areas could be switched off at once. This simple initiative is saving Vector Precision Engineering over £1,100 a year in electricity bills and 4.5 tonnes of CO2e a year.
Further cost savings of £1,700 a year have been made by replacing existing fluorescent lighting in the workshop with energy-efficient alternatives that have a payback period of less than a year on the cost of initial purchase and installation.
Tubular 'T8' lighting elements have been replaced with newer 'T5' tubes, which are 40 per cent smaller in size but can deliver an additional 15 per cent of light per watt of electricity.
This has also resulted in a further 6.6 tonnes of annual CO2e emission savings, helping to bring down the company’s carbon footprint, year-on-year.
'Well reasoned and practical'
Company director, Tony Bourne said: "In my view it makes a lot of sense for business and the environment; the advice from Groundwork Cheshire is free, well reasoned and practical."
In total, annual cost savings of £2,800 and electricity savings of 20,400 kilowatt-hours (kWh) a year have been achieved through lighting efficiency improvements alone.
Over the last two years these have accrued to give the £5,400 of cost savings to date and over 27 tonnes of CO2e savings.
Work is now ongoing to complete the upgrade of all lighting on site and to investigate further opportunities to improve the way other resources, such as water, materials and waste, are managed.
