This week on Better Buildings for Humans, host Joe Menchefski connects with Georg Molzer, Austrian tech visionary and creator of Shadowmap—a groundbreaking platform that’s redefining our relationship with sunlight. From early engineering dreams to burnout recovery and a brilliant balcony epiphany, Georg shares how a dark Viennese winter inspired him to illuminate how we understand solar exposure in cities, homes, and beyond. In this episode, Georg and Joe explore how Shadowmap’s intuitive 4D visualization tool is empowering architects, real estate developers, and everyday users to design healthier, more sun-filled environments. They dig into the rising global awareness of sunlight’s impact on health and productivity, and how data-rich simulations can prevent costly design mistakes. Whether you’re an architect, planner, or sunlight enthusiast, this conversation will make you think differently about how—and where—we build.

More About Georg Molzer

At the age of 16, while still attending high school, Georg Molzer had his first job as a programmer and designer for a Viennese health startup. Four years later, while studying visual computing at TU Wien, he founded his first consulting company. In 2015, he became co-founder and CTO of kiweno, an Austrian health tech startup, where he gained important entrepreneurial experience and went through the typical (and perhaps also less typical) founder’s journey.

His subsequent burnout and his love of the sun led him to follow his heart and work on an idea he had had six years earlier during a dark Viennese winter: an app that reconnects people with the sun: Shadowmap. Georg is convinced that the sensible use of solar energy – and the power of the sun in general – would solve many global problems in no time: better architecture, more livable living space, healthier and happier lives, higher, sustainable energy yields. Putting humanity first. His passion for the topic has turned Shadowmap into a globally leading product within a few years, which is used by hundreds of thousand people worldwide every month and is now also integrated into large real estate portals, reaching more humans than ever before.
