Energy Efficient Lighting - Case Study
Project: Cex Plymouth
This retailer contacted us in regards to upgrading their lighting in order to reduce their running costs.
The existing lighting was at least 7 years old and employed T8 switch start fluorescent fittings. Due to the age of the fittings the client was spending more and more each year on maintenance and replacement fittings.
Running cost savings.
There were significant savings to be made and the exmple below outlines the starting running costs against the cost of new fittings and installation costs.
Also, for this project, the client wanted us to make alterations to the ceiling to incorporate the new fittings and remove the existing fittings and lamps.
End Result
The client had a new looking store with higher lighting levels lights that consistently work all of the time with no maintenance costs for five years and no flickering lights.
A total saving of £36,000 on electricity costs was made for an an install cost of just £7,200. This added up to a total saving of £29,800.
The client also reduced their carbon emissions by 110.781 tonnes over the five year period.
The client also took the option on the ECA fitting and so will be able to claim tax relief as well at the end of their year financial year bringing further savings.
As a result of the success of the install and the savings made, the client is now looking at updating other locations
