In this talk, Prof. Jesus Lizana will present the latest research from the ZERO Institute at the University of Oxford on zero-carbon heating and cooling. The talk will examine the role of the building sector in achieving net-zero targets by 2050, drawing on new evidence from citizen-powered climate observations and projections to understand future shifts in heating and cooling demand. It will also showcase Oxford’s recent innovations in materials, software, and technologies to accelerate heating decarbonisation, alongside advances in sustainable cooling to support global climate adaptation. The presentation will discuss the key steps required to deliver resilient, net-zero building services worldwide.
