It bridges 2D building geometry (rooms, stories, buildings) to energy-analysis workflows by integrating with EnergyPlus for detailed thermal simulation, OpenStudio for advanced modeling, and URBANopt for district-scale urban energy analysis. The package lets you assign energy properties (program types, HVAC systems, window ratios) to building geometry and then export models to industry-standard formats like IDF or geoJSON for simulation.\n\nTypical workflow: define building geometry using Dragonfly's 2D room and story abstractions, assign energy program types and window parameters, convert the model to Honeybee format, and export to IDF or URBANopt geoJSON for simulation. The package handles the translation between Dragonfly's simplified geometric model and the detailed energy-simulation requirements of EnergyPlus and related tools.","worth_installing":"Yes. The package is actively maintained (released 2026-08-14), has low install friction, and integrates cleanly with the established Ladybug Tools ecosystem. It fills a clear role for developers and analysts building energy-simulation workflows in Python. The AGPL-3.0 license is a consideration for proprietary projects but standard in open-source building-simulation tools. No known vulnerabilities."},"id":"dragonfly-energy","links":{"html":"https://skillfed.io/packages/dragonfly-energy","md":"https://skillfed.io/packages/dragonfly-energy.md","pypi":"https://pypi.org/project/dragonfly-energy/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-08-14","license_spdx":null,"license_treatment":"agpl","name":"dragonfly-energy","python_support":"unspecified","summary":"Dragonfly extension for energy simulation."},"popularity":{"monthly_downloads":96377,"position":13215,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.45.20"}
