Retrofit realities: powered by modelling software

Introduction

Claire Brown welcomes Niall Gibson, Head of Sales at IES, to discuss the practical realities of delivering retrofit projects using building performance modelling. This episode focuses on how data-driven tools can support better planning, reduce uncertainty and create clearer pathways for decarbonising existing buildings at both project and portfolio scale.

With more than 15 years’ experience working across net zero carbon, new build design and retrofit projects, Niall shares his perspective on how modelling software can provide valuable insight into building performance, support long-term carbon strategies and help teams visualise outcomes before investment decisions are made. The conversation explores the role of software as a practical aid for local authorities, consultants, engineers and architects, highlighting how considered use of modelling can bring transparency, build confidence, and support informed, sustainable retrofit decisions.
