Dragonfly

This primer provides an overview of the Dragonfly components for Grasshopper.

The Dragonfly plugin supports the creation of models following the , which is an abstracted means of describing building geometry built on top of the plugin. By using a fundamentally 2D representation of Building geometry, where all rooms are assumed to be extrusions of floor plates, Dragonfly makes it easier to build models of large buildings all of the way up to the scale of urban districts. All Dragonfly models are translatable to Honeybee models and so all Dragonfly models can be simulated in the same engines as Honeybee, including / and .

However, Dragonfly makes it easier to create these simulation models from common 2D formats like . It also enables the connection to a wider array of simulation engines including:

Installation

Resources

for modeling of district thermal systems

for sizing transformers and electrical infrastructure

for life cycle cost optimization of photovoltaics

for estimation of urban heat island effects

See the for the installation instructions for the entire Ladybug Tools Grasshopper plugin (including dragonfly-grasshopper).
