‘We must move away from luminaire efficiency and look to design-led solutions based on energy consumption – it’s widely recognised that luminaire efficiency can only be driven so far, so we should change the way we measure efficiency now,’ said SLL secretary Liz Peck.
‘Enough people have lamented this aspect of Part L over the years and what’s needed now is for those people to support the SLL and its industry partners in making our case to the DCLG. It’s time to act.’
Although the next consultation for the 2013 and 2016 revisions to Part L is not released until this December, the deadline for lobbying is June.
‘We only have until June to act,’ said Peck. ‘This will be the only opportunity we have to change the metric until after 2016. Once the consultation has been released, we will not be able to change the method of measurement, only the detail. If we want to move to systems-based targets, now is the time to get them incorporated.’
The SLL believes the LENI metric measured in kWh/m2 is better.
