In this special in-person episode of Sunlight Matters, recorded on a sun-drenched rooftop terrace in Alicante, Dave and Georg are joined by daylight expert Paul Rogers to explore the profound relationship between sunlight, architecture, and human wellbeing.

From the emotional impact of dark living spaces to the life-changing benefits of solar exposure, the conversation blends personal stories with expert insight. The trio reflects on how sunlight shapes our mood, energy, and health—often subconsciously—and why access to natural light should be a fundamental priority in housing design.

They also dive into the science and strategy behind sunlight analysis, shadow mapping, and solar exposure, highlighting how tools and awareness can transform the way we design homes, cities, and living environments. The discussion reveals a powerful truth: whether it's a terrace in Spain or a skylight at home, access to sunlight is not a luxury—it’s essential.
