In this episode of An Hour of Innovation podcast, Vit Lyoshin speaks with Neall Digert, Vice President at Kingspan Light + Air, about how daylighting technology is transforming the way buildings use natural light.Vit and Neall explore how daylighting systems capture and redirect sunlight into buildings, reducing energy consumption while improving human health and productivity. They discuss how modern sustainable architecture can dramatically cut the need for electric lighting and why natural light plays a critical role in our biology and daily performance. The episode also dives into energy-efficient building design, the future of human-centric architecture, and how new technologies are making buildings smarter, greener, and more adaptable. Neall Digert is a leading expert in daylighting and sustainable building design and serves as Vice President at Kingspan Light + Air, a global company developing technologies that improve building performance and environmental sustainability. With decades of experience in architectural daylight systems, he has helped advance solutions that use natural sunlight to illuminate buildings while reducing energy use and carbon impact. Neall is also known for his work on the Solatube daylighting system, which uses optical technologies to capture, transfer, and distribute sunlight indoors. Takeaways* Daylighting technology captures sunlight on the roof and transports it through reflective tubes to illuminate interior spaces without electricity.* Natural daylight is one of the strongest biological signals for the human body, influencing sleep cycles, hormones, and alertness.* Buildings designed with strong daylight exposure can increase office productivity by about 6%, simply by improving the environment people work in.* A well-designed daylighting system can replace electric lighting for most of the day, reducing energy costs and carbon footprint.* The Solatube campus in California operates with electric lights only about 3% of the year, relying almost entirely on natural light.* Daylighting systems can guide sunlight through multiple floors and complex building structures, similar to “ducting” light like air.* Unlike standard windows, advanced daylighting systems can control how light is distributed inside a building, focusing, diffusing, or highlighting areas.* Lighting represents 40–75% of energy use in many commercial buildings, making it one of the biggest opportunities for energy savings.* Designing buildings for disassembly and recycling could dramatically reduce construction waste and enable true circular architecture.Timestamps00:00 Introduction01:38 What is Daylighting?02:21 Kingspan's Daylighting Solutions05:21 The Science Behind Daylighting Technology08:59 The Origins of Tubular Daylighting Devices11:52 Biological and Psychological Benefits of Daylighting19:36 Economic Advantages of Daylighting24:20 Challenges in Daylighting Technology Development27:55 Energy Positive Manufacturing at Kingspan33:40 Sustainable Building Practices36:50 Future of Building Design40:20 Circular Economy in Construction47:19 Innovative Materials and Technologies51:02 Innovation Q&AConnect with Neall* Website: http://www.kingspanlightandair.com/ * LinkedIn: https://www.linkedin.com/in/drnealldigert/ This Episode Is Supported By* Kit: Email marketing that automates your growth - https://partners.kit.com/xqcc7ca2ahlm * AdCreative.ai: Generate ad banners, texts, photoshoots, and videos that outperform those of your competitors - https://free-trial.adcreative.ai/velg2js91det-96w1li * Leadpages: All-in-one conversion rate optimization solution - https://try.leadpages.com/jorgsmx8wadw For inquiries about sponsoring An Hour of Innovation, email [email protected] Connect with Vit* LinkedIn: https://www.linkedin.com/in/vit-lyoshin/ * Substuck: https://anhourofinnovation.substack.com/ * X: https://x.com/vitlyoshin * Podcast: https://www.anhourofinnovation.com/
