How Efficient is your Lighting Scheme?

Keeping a close eye on energy consumption and sustainability is on top of everyone’s agenda. Using the latest LED technology is a given but just using the technology without a professionally produced lighting design won’t make the scheme efficient (or visually comfortable for that matter).


The energy consumption of a lighting installation can be significantly reduced by the introduction of lighting controls.


Over the years, we have been witnessing a shift from lighting controls being a ‘nice to have” and then becoming a subject to value engineer, to a necessity for a scheme to meet compliance with current building regulations. The forward-thinking schemes are now using wireless lighting controls as an integrated part of the intelligent buildings.

So with a calculator in one hand and a desire to create beautiful spaces, how do we make sure that a lighting scheme focusing on energy consumption doesn’t fall back on the performance and design? And how do we actually ‘label’ a scheme as efficient?

There are several methods of making sure your scheme is performing well in terms of energy efficiency and each practice or client would choose to go down a different route.


The first one is LENI, a metric for calculating lighting installation energy over time. LENI comes up in every lighting textbook as a prelude to lighting regulations and allows the designer to use less efficient luminaires in some places, balanced by highly efficient luminaires used elsewhere.
