In this illuminating episode of Sunlight Matters, David Wallace is joined by Niko Gentile and Agnieszka Czachura from Lund University’s Energy and Building Design group. Together, they explore the science, perception, and policy around sunlight and daylight, and why we need to care more than ever.
From the overlooked distinction between daylight and sunlight to the historical biases in building regulations, Niko and Aga take us on a fascinating journey. We discuss Agnieszka's new research into how people value sunlight in their homes today, revealing that although people still crave light, their reasons for doing so have shifted in our modern, thermally controlled, and urbanised world.
We also examine how energy-efficient building codes risk undermining human well-being, why real estate agents might be the best sunlight psychologists, and how the physics of glass may be blinding us to the sun’s full health benefits.
If you’ve ever felt better on a sunny day but didn’t know why, this episode is for you.
Sunlight Matters is a podcast exploring the role of the Sun in human health, architecture, cities, and everyday life.
Through conversations with scientists, architects, and technologists, the series examines how natural light shapes our bodies, our buildings, and the way we live indoors.
Hosted by Dave Wallace, Sunlight Matters asks a simple but overlooked question: what happens when we disconnect from the Sun?
Because sunlight isn’t optional. It matters.
