Abstract

This study, examining a Passivhaus retrofit in London, investigates optimum pathways for non-domestic low energy retrofits in the UK, capable of preserving their low energy status in future changing climates. A methodological framework is deployed, utilizing multi-objective optimisation (MOO) techniques and setting three conflicting objectives: building’s annual energy use, occupants’ discomfort, and retrofit’s Net Present Value. The results highlight the potential of this methodological framework to provide an essential aid to the early-stage decision-making phase of building retrofits, identifying solutions which would be more resilient in future climates. Findings emphasize the capability of MOO analysis to demonstrate distinct differences between widely preferred energy-efficient measures and solutions considered “optimum”, whilst analysing the Pareto optimums obtained for future climates, gradual adaptation measures can be identified.
