Episode 76 - Buildings as Energy Machines: When Buildings Become the Grid feat. Nicolas Kastbjerg

from Inventing Construction · host KOSMOS

The reality is this: our buildings are full of surplus energy. And we waste most of it.Across offices, hotels, hospitals, and data centres, enormous amounts of heat are generated every single day. Ventilation systems blow it away. Cooling systems spend electricity to remove it. Mechanical systems operate in isolation, unaware that the building next door might need exactly the energy being thrown away.So perhaps the question isn’t how do we produce more energy? But how do we stop wasting the energy we already have?In today's podcast episode, we speak with Nicolas Kastbjerg, CEO of Energy Machines, about a different way of thinking about building energy systems. One where buildings are not just consumers of energy, but active participants in the energy system itself.Or put simply: Buildings as energy machines.What you'll learn from today's episode of Inventing Construction:- What is energy as a service?- What are the low-hanging fruit of energy efficiency?- Concrete examples of hidden energy waste- Regulatory and market barriers to energy transformation- The mindset shift needed to change our energy systemLink to Fælledbyen: https://faelledby.dk/You can also listen to Inventing Construction on these platforms:Spotify: https://open.spotify.com/show/2aAxc0iqOe2JJly3jCh9jV?si=8db208888a9a4e4cApple podcast: https://podcasts.apple.com/us/podcast/inventing-construction/id1629403210YouTube: https://www.youtube.com/playlist?list=PLmFqJlVzEa6Lc_7LOTjvac2oTbRRk9HdKWe would love for you to continue the conversation with us on LinkedIn:Ross: https://www.linkedin.com/in/ross-griffin-kosmos/Elia: https://www.linkedin.com/in/eliaarquitectatecnica/Nicolas: https://www.linkedin.com/in/nicolas-kastbjerg-33505724/KOSMOS: https://www.linkedin.com/company/kosmos-dkThanks for listening!

Each episode focuses on a pivotal event, a transformative figure, or a defining idea—whether it's the construction of the Great Wall, the mind of Empress Wu, or the invention of paper money—weaving them into the grand tapestry of the dynastic cycle. The tone is authoritative yet vividly human, making emperors, poets, and peasants alike feel immediate and real.
