More on Light Pipes: Aussie Grad Student Develops New Collector

Treehugger has covered a lot of light pipe schemes recently, and show one here developed by Veronica Garcia Hansen, a PhD student from the Queensland University of Technology in Brisbane. We quote Veronica:

“Most systems use complicated and expensive sun tracking systems. Our solution has no mobile parts, and is completely passive, therefore reducing operation and maintenance costs.”

“We realised that a simple device known as laser cut acrylic panels, would passively redirect sunlight inside the pipe. This reduces the number of light reflections along it, thereby increasing the performance.”

Now we do not want to be too critical of Veronica in her project here, but using light pipes to bring natural light into a building is no substitute for properly designing a building in the first place so workers have a decent environment. Nobody should have to sit 30 metres from a window for half of their waking life. The images here are oppressive with or without natural light.

So points to Veronica for a clever solution to the wrong problem- Lets demand better working conditions with windows and fresh air and views, not piped air and piped light and Microsoft backgrounds as the only trees and plants that we ever see.
