Getting the basics right: Data, buildings & behaviour
Many organisations have ambitious net zero targets. The challenge is delivering them. In this episode of Talking Power, host Tim McManan-Smith is joined by Lewis Welch, Head of Energy Transition at Dalkia , part of EDF, to discuss the practical realities of decarbonising buildings and estates. From ageing infrastructure and limited budgets to behavioural change, data quality and operational complexity, Lewis explains why successful decarbonisation starts with understanding how buildings are actually used and managed. The conversation explores common sources of energy waste, why organisations often overlook optimisation in favour of new technology, and how smarter building management can unlock immediate savings while creating a stronger foundation for long-term decarbonisation. Lewis also discusses the growing role of flexibility services, the importance of good-quality data, and why organisations should focus on getting the basics right before turning to AI and other emerging technologies.
