# CBE Thermal Comfort Tool

The CBE Thermal Comfort Tool is a free online tool for thermal comfort calculations and visualizations that implements thermal comfort calculations from standards ([ASHRAE 55–2023](https://webstore.ansi.org/standards/ashrae/ansiashraestandard552023), [ISO 7730:2005](https://www.iso.org/standard/39155.html) and [EN 16798–1:2022)](https://www.en-standard.eu/din-en-16798-1-energy-performance-of-buildings-ventilation-for-buildings-part-1-indoor-environmental-input-parameters-for-design-and-assessment-of-energy-performance-of-buildings-addressing-indoor-air-quality-thermal-environment-lighting-and-acoustics-mod/).

It incorporates the major thermal comfort models, including the ASHRAE and ISO Predicted Mean Vote (PMV), Standard Effective Temperature (SET), adaptive models, local discomfort models, SolarCal, and dynamic predictive clothing insulation. Our tool also provides dynamic and interactive visualizations of the thermally comfortable conditions depending on the models.

In addition, the CBE Thermal Comfort Tool allows users to upload time-series or large sets of input parameters and it automatically calculates PMV, PPD, SET, and CE. This may allow users to perform exceedance predictions (e.g. annual or seasonal) for simulated or real buildings.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://cbe-berkeley.gitbook.io/thermal-comfort-tool/readme.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.
