# Process Alleys

![](/files/BSOqwPqYg8nVV6sFAhy5) - [\[source code\]](https://github.com/ladybug-tools/dragonfly-grasshopper/blob/master/dragonfly_grasshopper/src//DF%20Process%20Alleys.py)

Remove windows from any walls that are within a certain distance of other buildings.

The component can also optionally set the boundary conditions of these walls to adiabatic. This is helpful when attempting to account for alleys or parti walls that may exist between buildings of a denser urban district.

### Inputs

* **buildings \[Required]**

Dragonfly Building objects which will have their windows removed if their walls lie within the distance of another building. This can also be an entire Dragonfly Model.

* **distance**

A number for the maximum distance of an alleyway in Rhino model units. If a wall is closer to another Building than this distance, the windows will be removed. (Default: 1.0 meters).

* **adiabatic**

A boolean to note whether the walls that have their windows removed should also receive an Adiabatic boundary condition. This is useful when the alleyways are more like parti walls than distinct pathways that someone could traverse.

### Outputs

* **report**

Reports, errors, warnings, etc.

* **buildings**

The Building objects with their windows removed from any detected alleys.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ladybug.tools/dragonfly-primer/components/0_create/process_alleys.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
