Decarbonising Heritage Estates: Engineering Pathways to Practical Net Zero

It will cover how overheating analysis informs passive interventions, climate resilience and system sizing; how stepped decarbonisation pathways can be sequenced around estate planning and existing MEP limitations; and how ASHP‑based solutions can be integrated within legacy systems despite acoustic, spatial and control challenges. The talk also examines stepped control strategies—flow‑temperature optimisation and hybrid operating modes.
