Low energy lighting saves Debenhams, Waterford 35% on light costs


The Project

With over 150 stores in the UK and Ireland Debenhams is one of the leading department stores group. In the Waterford facility, areas are fully lit for 12 hours a day. Debenhams Waterford decided to use Save It Easy® to upgrade 2560 lamps to low energy lighting.


At the Waterford store, Energy Sense Ireland and Debenhams calculated  that on lighting alone 35% savings were possible. In February 2009, based on these calculations over 2560 lamps were converted with no disruption to the every day workings of the store.

The Savings

As a result of installing the Save It Easy® units, annual energy cost saving of €33,000 and CO2 emissions savings of 105 tones will be achieved. This installation was concluded in February 2009 over two weeks with 35% savings on lighting costs.

Project Payback and Comments

Including annual maintenance cost and product savings -: 12 months.
Quote: Firstly can I say I have had a huge benefit changing from Warm White to Cool White. Based on our EMS we have dropped 30kw from our load since we have installed Save It Easy® which will direct me into my 12 month payback for my project.
Having running periods of 12hours everyday , by using T5 energy efficient tubes as opposed to T8 it will have great payback for Debenhams. Overall it is a very good step forward and it will be taken as a measure in the rest of the Debenhams stores.
