# Credits

Credits help you run more advanced simulations, faster. While simple models run for free in your browser, larger or more detailed projects need extra computing power. That’s where credits come in. They let you tap into our high-performance servers, generate in-depth simulation reports (with the Lite Plan), and process complex models faster and more efficiently. 

## Detailed Reports

To generate a detailed report on the Lite Plan, Credits must be pre-purchased. Credit bundles are available in 50, 250 (20% discount), 500 (30% discount) and 1000 (40% discount) quantities, offering greater value with higher volumes.

## Processing Large or Complex Models

Credits are a game-changer for processing large models on our secure server, delivering speeds up to 10 x faster than local desktop simulations. A 60-minute energy simulation can now finish in just 6 minutes!

To leverage enhanced performance, Credits are required for large models (>10,000 m² or 100+ thermal zones) or complex simulations. They’re optional for small to medium models.

Credit use per simulation is based on project size:

* Small (0 – 4999 m²): 1 Credit
* Medium (5000 – 9999 m²): 2 Credits
* Large (10,000 m²+): 5 Credits
* Moisture simulations: 1 Credit

| Model Size              | Energy + Daylight | Moisture |
| ----------------------- | :---------------: | :------: |
| Small (0 - 4999 m²)     |         1         |     1    |
| Medium (5000 - 9999 m²) |         2         |     -    |
| Large (10,000 m² +)     |         5         |     -    |

## Buy Credits

Credits can be purchased directly on the platform in your Team settings. They’re also included in all annual subscription packages for added value and flexibility.

# 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 by asking a question.

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

```
GET https://docs.betterbuilding.io/sign-up-and-plans/plans/credits.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.
