Background
Created through the acquisition of four market leading brands, the National Timber Group is the largest independent added-value timber distribution and processing group in the UK.
A favoured supplier of large-scale infrastructure projects, the Group serves a diverse customer base including joiners, housebuilders and contractors.
With over 20 sites requiring complete refits throughout Scotland alone, it was important for the National Timber Group to find the right LED lighting solution to roll out across the brands.
Rembrand Timber Ltd
We wanted to show the quality of our work by completing the first job prior to any contract being drawn up. We knew the results would speak for themselves. We began with the Rembrand Timber Ltd Selkirk site in 2019 which then secured a contract to complete over 20 other sites in Scotland in 2020.
WAREHOUSE 80 watt high bays
SMALL STORES 5ft twin and 5ft single fittings
KITCHEN AND OFFICE 18 watt tubes
CAR PARK 50 watt floodlights
The results
We think the results speak for themselves in the following before and after photos and predicted annual savings.
Projected annual savings
The projected per annum savings for the Selkirk site are as follows.
67% energy output reduction
12,244.32 KwH
£1,667.40
6.6 tonnes carbon emissions
Brighter, safer environment
The floor markings were barely visible and it was difficult to see the stock before the refit.
There has been a vast improvement in visbility helping create a brighter, safer environment for the staff.
Total annual savings
With the project completed across the National Timber Group sites, the total annuals savings make impressive reading.
69% energy output reduction
495,756.93 KwH
£67,901.06
115 tonnes carbon emissions
