# dragonfly-energy
Dragonfly extension for energy simulation, including integration with the
[EnergyPlus](https://github.com/NREL/EnergyPlus) simulation engine, the
[OpenStudio](https://github.com/NREL/OpenStudio) SDK, and the
[URBANopt](https://docs.urbanopt.net/) SDK.
## Installation
`pip install dragonfly-energy`
To check if Dragonfly command line interface is installed correctly
use `dragonfly-energy --help`.
## QuickStart
```python
import dragonfly_energy
```
## [API Documentation](http://ladybug-tools.github.io/dragonfly-energy/docs)
## Usage
Since the building geometry in dragonfly is fundamentally 2D, creating a model of
a building and assigning energy model properties can be done with a few lines of
code. Here is an example:
```python
from dragonfly.model import Model
from dragonfly.building import Building
from dragonfly.story import Story
from dragonfly.room2d import Room2D
from dragonfly.windowparameter import SimpleWindowRatio
from honeybee_energy.lib.programtypes import office_program
# create the Building object
pts_1 = (Point3D(0, 0, 3), Point3D(0, 10, 3), Point3D(10, 10, 3), Point3D(10, 0, 3))
pts_2 = (Point3D(10, 0, 3), Point3D(10, 10, 3), Point3D(20, 10, 3), Point3D(20, 0, 3))
pts_3 = (Point3D(0, 10, 3), Point3D(0, 20, 3), Point3D(10, 20, 3), Point3D(10, 10, 3))
pts_4 = (Point3D(10, 10, 3), Point3D(10, 20, 3), Point3D(20, 20, 3), Point3D(20, 10, 3))
room2d_1 = Room2D('Office1', Face3D(pts_1), 3)
room2d_2 = Room2D('Office2', Face3D(pts_2), 3)
room2d_3 = Room2D('Office3', Face3D(pts_3), 3)
room2d_4 = Room2D('Office4', Face3D(pts_4), 3)
story = Story('OfficeFloor', [room2d_1, room2d_2, room2d_3, room2d_4])
story.solve_room_2d_adjacency(0.01)
story.set_outdoor_window_parameters(SimpleWindowRatio(0.4))
story.multiplier = 4
building = Building('OfficeBuilding', [story])
# assign energy properties
for room in story.room_2ds:
room.properties.energy.program_type = office_program
room.properties.energy.add_default_ideal_air()
# create the Model object
model = Model('NewDevelopment', [building])
```
Once a Dragonfly Model has been created, it can be converted to a honeybee Model,
which can then be converted to IDF format like so:
```python
# create the dragonfly Model object
model = Model('NewDevelopment', [building])
# serialize the dragonfly Model to Honeybee Models and convert them to IDF
hb_models = model.to_honeybee('Building', use_multiplier=False, tolerance=0.01)
idfs = [hb_model.to.idf(hb_model) for hb_model in hb_models]
```
The dragonfly model can also be serialized to a geoJSON to be simulated with URBANopt.
```python
from ladybug.location import Location
# create the dragonfly Model object
model = Model('NewDevelopment', [building])
# create a location for the geoJSON and write it to a folder
location = Location('Boston', 'MA', 'USA', 42.366151, -71.019357)
sim_folder = './tests/urbanopt_model'
geojson, hb_model_jsons, hb_models = model.to.urbanopt(model, location, folder=sim_folder)
```
