Dragonfly enables the creation of district scale energy models through the use of an abstracted building geometry schema. Dragonfly models can be translated directly into detailed 3D Honeybee models but can also be simulated directly in a variety of engines. Energy simulations of Dragonfly models can be run with the URBANopt SDK, which leverages OpenStudio and EnergyPlus. Energy simulation results can be used to simulate loads on electrical electrical infrastructure with OpenDSS, and can also be incorporated into cost-optimization of renewables with REopt. Lastly, any dragonfly model can be used to morph rural EPW files to account for the urban heat island effect using the Urban Weather Generator (UWG).
