Create an EnergyPlus shade construction. Note that Shade objects in EnergyPlus do not have layers and are only defined by their exterior reflectance.

## Inputs

* **name**

  Text to set the name for the Construction and to be incorporated into a unique Construction identifier. 
* **sol\_ref**

  A number between 0 and 1 for the solar reflectance of the construction. Default: 0.2. 
* **vis\_ref**

  A number between 0 and 1 for the visible reflectance of the construction. Default: 0.2. 
* **specular**

  A boolean to note whether the reflection off the shade should be diffuse (False) or specular (True). Set to True if the construction is representing a glass facade or a mirror material. Default: False. 

## Outputs

* **constr**

  A shade construction that can be assigned to Honeybee Shades or ConstructionSets.
