When considering an upgrade of out-dated or energy inefficient lighting, it is often tempting to go for a ‘quick win’. Whilst this may often seem attractive, consideration should be given to the potential increased benefits of a deeper renovation.
Maxim Logistics replaced outdated fluorescent luminaires with new ones and saw a 40% reduction in energy. Read the case study in the Lighting Technology Overview Guide (CTV049)
When deciding upon whether to embark on an upgrade of existing equipment (retrofit), or a larger refurbishment, there are some key questions to ask:
If you have answered ‘No’ to more than three of these questions, then you should consider a refurbishment to maximise the energy savings possible.
Luminaires using T12 (38mm diameter) or T8 lamps (24mm) may be suitable for upgrading to T5 (16mm) by replacing both lamps and gear; it may be necessary to update the optics as well. T5 luminaires can be up to 60% more efficient than older fluorescent technology.
Lighting controls can be retrofitted to existing lighting, often without the need for any significant rewiring. Occupancy and daylight sensors can save up to 25% of energy. View the videos to see how in the Introduction page or download our guide, How to implement lighting controls (CTL133).
