Occupant-Centred Controls for Human-Centric lighting? – and notes for sun-seekers

I’ve been reading a lot about ‘Smart Buildings’ recently.

Lots of information out there including this event on Thursday – IES Webinar Series – Toward to “Lighting 4.0” Era, the SSL2 (Sustainable Smart Lighting x Solid State Light sources) Concept

It’s easy to see why –


Occupant-Centred Control may hold the key – and the extra cost could end up being great value if you factor in the benefits in terms of employee satisfaction and energy cost reduction. 

Research shows that when we feel in control, we feel more satisfied with our work place.  Satisfaction in turn boosts how productive we feel and how good we feel about our employer too. 
We even make more eco-friendly choices when left to our own devices – 
Letting occupants choose whether to switch the light on or not reduced electricity by 17.8% without any upfront investment and major technical modification – The Influence of the Environment and Clothing on Human Exposure to Ultraviolet Light

As many of us get ready for a break…

Here are some notes about the good, the bad and the ugly side of sunshine…

The solution?

  • Rise and shine – Get your fix early morning and late afternoon when UV levels are lowest
  • Cover up – A big hat, sunglasses and close-weave fabric clothes and seek out shade when you can. 
  • Protect – Slop on a safe sunscreen every two hours every day – more if outside or sweating. Dr. Harvey Lui, dermatologist at the BC Cancer Agency: “Sunscreen is like wearing a seatbelt and air bags – doesn’t mean you should drive like crazy!’ – Five myths about sun protection

As you read this, I’ll be on my way to bask in the glow of Greek sunshine.

A highlight in every sense will be the new lighting scheme at the Acropolis, described by this outstanding presentation by Florence Lam. She begins with a favourite quote from the great Frank Lloyd Wright: “Beautiful buildings are more than scientific. They are true organisms, spiritually conceived: works of art using the best technology.”
