I delivered a presentation about Gunnar Asplund’s Stockholm Public Library and Asplund’s use of daylight to generate the building design. To see a video of the presentation at the 6th Velux Daylighting Symposium in London, use this link: http://thedaylightsite.com/symposium/2015-2/presentations/ and scroll down to the 3 September 2015 Morning session and you’ll find the video. At this location, you’ll also find a brief written version of the presentation.
