Lighting the way to building performance
Written by Liz Peck MSc FSLL, Design Principal at LPA Lighting, President Elect Society of Light & Lighting and Judge of the Building Performance Awards 2015
Any lighting geek - for I
am one - will tell you that lighting is the single most important component of
building services. I know there are
those who will argue for HVAC and others but honestly, I've got jumpers for
winter months and in my office, I've got open windows delivering fresh air
and - even more importantly - a bucket-load of daylight; for I am also a
daylight freak and I countenance people having daylight breaks during their
working day; daylight is good for you and that's official.
Even putting to one side
the benefits to well-being, daylight is also a driver in energy-efficient
lighting; I don't remember the last time a light was on in my office but it
would have been before the clocks changed in March. Harvesting daylight and controlling the
lighting accordingly means the bare minimum of artificial energy is used for
lighting and it's not rocket science in terms of controls either: simple but
effective lighting controls means the old adage of lights only being on when
they are needed actually rings true, whether daylight- or occupancy-based control.

For the first time,
lighting is being recognised as a stand-alone award in the annual CIBSE
Building Performance Awards. With
lighting playing such a dominant role in electricity costs of commercial
buildings - up to 40% - the time has rightly come to reward schemes focused on
lighting alone - and bringing opportunity for recognition to lighting designers
and other companies who are delivering lighting schemes.
I read once that employing a specialist
lighting designer will typically result in 30% less energy being used on the
project - and who am I to argue with such a great statistic? It's not just about energy, of course,
occupant feedback and quality of the design will be considered, most likely
above everything else. But as all those same lighting geeks will tell you,
quality design and energy efficiency are not mutually exclusive, by definition,
great design will be efficient.
