The ‘Future Weather Generator’ is a Java app for researchers and building design professionals. The app morphs hourly EPW files, used in dynamic simulation programs like EnergyPlus, to match future climate change scenarios.

The app is free, open-source, and cross-platform. Researchers can use the app as a standalone tool or integrate it into their research code. Building design professionals can also use this app to create future weather data to evaluate a building’s future energy performance.

Currently, ‘Future Weather Generator’ has implemented the following general circulation models’ experiments:

There is also ‘Future Weather Generator PT Ed.‘, which covers Portugal’s mainland and utilizes the following regional climate model:

  • WRF (baseline 1995-2014)
    • Shared Socioeconomic Pathways:
      SSP2-4.5, SSP3-7.0, and SSP5-8.5
    • Timeframes:
      2055 (2046-2065)
      2090 (2081-2100)
    • Monthly changes:
      Median of the twenty months in the timeframe
      Median of the five hottest months from the timeframe
      Median of the five coldest months from the timeframe
    • Grid points:
      8,400 (120 latitudes by 70 longitudes)
