# ASCE 7-10/16 Wind Enclosure

How to determine a building's enclosure classification for wind loads per ASCE 7-22, 7-16, and 7-10.

This module is an implementation of the provisions for determining the Enclosure Classification for the determination of Wind Loads as per ASCE 7.

![](https://3283832020-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FiBJmBoewuy4ZcBC7RF3m%2Fuploads%2Fgit-blob-c38f44c883c26361e131f68fdbe770c91730b233%2Fclip0415_was_BMP.jpg?alt=media)

The module currently supports calculations based on ASCE 7-22, ASCE 7-16 and ASCE 7-10. Input parameters are taken directly from the nomenclature presented in ASCE 7.

The ASCE 7-16 and ASCE 7-10 calculation sheet is set up to permit up to ten different analyses to be documented within a single Project File. The ASCE 7-22 calculation sheet is set up to permit a single analysis per instance, but multiple instances can be added when a project includes multiple buildings, or in situations where multiple scenarios are being evaluated.

The data collection is presented in such a way as to guide the user through the module in a logical progression.

Values of gross area and area of openings are provided for walls on four sides of the building (arbitrarily designated "North", "South", "East", and "West"). Once these values are provided, the module can determine if the structure qualifies as "Open" or not. If the structure is determined to be "Open", then the module will indicate that result and stop there. If the structure does *not* qualify as an "Open" structure, then input fields for Roof Gross Area and Roof Opening Area will be displayed, and a set of four tabs will appear in the bottom half of the screen. Once the Roof areas are populated, the four tabs thoroughly present the calculations to determine whether the structure qualifies as "Enclosed" or "Partially Enclosed" when each of the four respective walls receives positive external pressure. The ASCE 7-22 version of the module also incorporates the newly added "Partially Open" enclosure classification.

The results of this determination are useful for project documentation requirements, as well as in guiding the user to read the appropriate results values from other modules within ENERCALC SEL.

{% hint style="info" %}
Note: The provisions of the ASCE Wind Enclosure module are already incorporated into the ASCE 7 Wind Loads modules. So it is not necessary to run the standalone version of this module if the ASCE 7 Wind Loads modules will be used.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://enercalc.com/docs/sel-user-manual/calculation-modules/general/asce-wind-enclosure.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
