Building performance and solar energy system simulations are typically undertaken with standardised weather files which do not generally consider future climate predictions. This paper investigates the generation of climate change adapted simulation weather data for locations worldwide from readily available data sets. An approach is presented for 'morphing' existing EnergyPlus/ESP-r Weather (EPW) data with UK Met Office Hadley Centre general circulation model (GCM) predictions for a 'medium-high' emissions scenario (A2). It was found that, for the United Kingdom (UK), the GCM 'morphed' data shows a smoothing effect relative to data generated from the corresponding regional climate model (RCM) outputs. This is confirmed by building performance simulations of a naturally ventilated UK office building which highlight a consistent temperature distribution profile between GCM and RCM 'morphed' data, yet with a shift in the distribution. It is demonstrated that, until more detailed RCM data becomes available globally, 'morphing' with GCM data can be considered as a viable interim approach to generating climate change adapted weather data.
