Ferdinand Grapperhaus believes the future of real estate performance lies in using better data, AI and automation to make buildings more efficient, responsive and easier to operate.
In this episode, Ferdinand Grapperhaus, CEO and Co-Founder of NextSense, explains why collecting building data is only the beginning. NextSense combines structured building data, AI agents and building physics to help owners, occupiers and operators identify performance gaps, improve energy efficiency, reduce costs and maintain high levels of comfort across real estate portfolios.
The conversation explores the journey from analogue buildings to truly intelligent assets, and why many buildings already have the technology they need but still fail to perform as intended. Ferdinand discusses the challenges created by disconnected systems, fragmented data and overstretched facilities teams, and why dashboards alone are not enough. Instead, AI can analyse building performance continuously, identify issues, recommend interventions and increasingly take direct control of building settings.
The discussion also examines how AI can optimise heating, cooling, ventilation, thermal comfort and even blinds in real time. Ferdinand shares real-world examples including £250,000 in energy cost savings across ten assets and potential energy reductions of 10–15% through better control of blinds alone. He also explains why operational optimisation should often come before major retrofit decisions, allowing building data to inform where CapEx will have the greatest impact.
