With 80% of the built environment already in existence today, the choices we make in delivering low carbon, environmentally considered solutions must go beyond simply considering the operational efficiency of an installation. This presentation will look at what good lighting looks like for an existing space and how we can utilise already installed assets to deliver the lowest carbon impact without compromising on the needs of people. Presented by Tim Bowes MSLL, Head of Lighting Application at Whitecroft Lighting.

7. The need for regeneration
“Newly constructed buildings are more energy efficient,
but 80% of buildings in 2050 have already been built, so
a major priority is decarbonising our existing stock.”

8. “The Act of improving a place or
system, especially by making it
more active or successful”
