Dragonfly

Dragonfly is a Rhino/Grasshopper plugin that models urban-scale climate and energy systems, integrating thermal satellite imagery with tools like EnergyPlus, REopt, and Urban Weather Generator. It supports sustainable city planning by simulating energy use, carbon emissions, and urban heat islands. Dragonfly models can be directly translated into detailed 3D Honeybee models or simulated in various engines for flexible and comprehensive analysis.

Dragonfly is a versatile Rhino/Grasshopper plugin for modeling urban-scale climate phenomena and energy systems, such as urban heat islands, district energy usage, and renewables optimization. It integrates datasets including thermal satellite imagery (e.g., Landsat) to visualize spatial temperature distributions and supports tools like EnergyPlus, URBANopt, and REopt for detailed simulations. Users can analyze annual energy use, operational carbon emissions, peak loads, and district thermal system opportunities, enabling efficient energy planning.

Dragonfly's capabilities extend to retrofitting incentives, electrical grid loading, and optimizing renewable investments across districts. It facilitates the creation of district models from various geometries, such as building footprints or detailed floor plans, and supports GeoJSON integration for easy data handling. Additionally, the tool morphs EPW files to include urban heat island effects and creates AMY files for recent years using publicly available data.

Dragonfly’s ability to integrate such diverse datasets makes it an invaluable resource for urban climate analysis and energy planning. Its flexibility and comprehensive features make it ideal for urban climate and energy planning.
