In this episode of Sunlight Matters, Dave sits down with the brilliant Paula Longato—architect, daylight consultant, and lighting designer—to explore why daylight access and sunlight analysis are critical yet often overlooked elements in urban design and architecture.

🎙️ What You'll Learn:

• Why modern cities like New York and Dubai are "dark daylight cities" 🌆
• The role of shadow mapping and solar exposure in creating healthier urban environments
• How real estate sun studies can shape better buildings and energy-efficient homes
• The silent power of green light, and how vegetation affects our mental and physical health 🌿
• Why vernacular architecture holds the key to future-ready, climate-conscious cities
• The untapped potential of darkness design and the physiological dangers of over-illumination 🌒

💡 Paula shares her journey from sun-soaked São Paulo to the grey skies of Germany—and how that shift sparked a lifelong passion for daylight architecture and sunlight-responsive urban planning. Together, they tackle the complexities of building orientation, facade engineering, and circadian lighting, offering a holistic view of how we can—and must—build better with the sun in mind.

🌇 Whether you're an architect, city planner, homebuyer, or just someone chasing sunlight, this episode will shift the way you think about the built environment and your place within it.

Dave sits down with Ulysse Dormoy, CEO of Atrium Ltd, to explore a subject hiding in plain sight: the light we live under every day — and how it’s quietly impacting our health, performance, and wellbeing 🌞🏙️

What starts as a conversation about lighting design quickly reveals a much bigger story. From LED flicker and infrared deprivation, to the shocking parallels between ultra-processed food and ultra-processed light, Ulysse shares his journey into the world of light as a biological force.

We dive into:
🔎 How modern offices and homes are robbing us of essential light
🌿 Why sunlight exposure, shadow mapping, and solar orientation matter more than ever
🧠 The science behind photobiomodulation and its rising popularity
🏢 The silent health risks baked into energy-efficient architecture
🚶‍♂️ What designers, planners, and employers can do to build truly healthy environments

You’ll also hear why Ulysse carries a spectrometer everywhere, what happens when beauty brands get lighting wrong, and how we might be heading towards a "lighting tobacco moment" — where health meets accountability ⚠️

Whether you're an architect, designer, developer, or just spend too much time indoors, this episode will change the way you think about light, space, and health forever 🌇

What if everything you thought you knew about sunlight was just scratching the surface? ☀️🔬

In this illuminating episode of Sunlight Matters, hosts Dave and Georg sit down with world-renowned astrophysicist Dr. Bob Fosbury — a former senior scientist with the European Space Agency, key contributor to both the Hubble and James Webb Space Telescopes 🔭, and a trailblazer at the intersection of astronomy, biology, and human health.

🌌 From black holes and the Big Bang to mitochondria and macular degeneration, Bob connects the dots between cosmic light and cellular life in a way that’s as profound as it is practical. This is not just science — this is a blueprint for how to live in harmony with the energy source that powers everything on Earth: the Sun.

🎙️ Together we explore how infrared light, once overlooked, is now recognized as vital for metabolism, ageing, mitochondrial health, and even mental clarity. You’ll understand why modern architecture, LED lighting, and indoor living might be depriving us of essential solar wavelengths — and what steps we can take to reconnect with full-spectrum sunlight in our homes, cities, and everyday lives.

☀️ In This Wide-Ranging Episode, We Cover:

• 🌌 The origins of light — and how it shaped the universe
• 🌱 How photosynthesis and metabolism mirror the thermodynamics of stars
• 🧬 The role of infrared light in mitochondrial function and ATP production
• 🚨 Why white LED lights may be disrupting human biology and increasing disease risk
• 🏢 How urban planning, window glass, and building design limit natural solar exposure
• 🧠 How entropy, aging, and light are intimately connected
• 🧭 Why understanding the energy flow of life can help us build healthier, more sustainable systems
• 🌞 The future of sunlight-based health interventions, lighting design, and planetary living

Whether you're a curious mind, an architect, a real estate professional, a health practitioner, or someone exploring the science of sunlight for personal vitality, this episode offers new frameworks, ancient truths, and practical insights. You’ll never view the Sun (or your indoor lights) the same way again.
