Future Weather Files

The future weather files are synthesized based on the research project on climate change impact on building energy performance. These weather files (in EPW format) are intended to be used for building energy simulation and performance evaluation. The team has provided here future weather files for 30 years (from 2020 to 2049) for a few locations for all four Representative Concentration Pathways (RCP2.6, 4.5, 6.0, and 8.5) used in the Fifth IPCC (Intergovernmental Panel on Climate Change) Assessment. Due to limited resources, weather files for other locations will be added slowly but surely. If you have any pressing needs, you are welcome to contact the team to explore the possibility. The future weather files are synthesized based on a workflow developed by the team. A full explanation is presented in our article (link), copied here is a brief description: The effect of climate change is based on General Circulation Models (GCM). First, a bias-correction technique, known as the quantile-quantile method, is applied to remove the bias in the data in order to adopt GCMs to a specific location. The study then uses a hybrid classification-regression model to downscale the bias-corrected GCM data to synthesize future weather data at hourly resolution for building energy simulation. The proposed workflow enables users to use a set of observed weather data by finding similar patterns rather than artificially generating data. However, in cases where the future GCM data showed temperatures ranging outside of the observed data, the study applied a trained regression model to synthesize hourly weather data.
