In a recent podcast conversation, we discussed daylighting systems that capture sunlight on rooftops and transport it through reflective tubes to illuminate interior spaces. The concept isn’t new, but it raises an interesting question about why so many modern buildings still depend heavily on electric lighting even when natural light is available.

It made me think that sustainable design might be less about adding more energy systems and more about designing buildings that simply need less energy in the first place.

Curious how people here see it. Could daylighting become a default design principle in future buildings?
