# New Climate Feature

As of today, you'll find a brand new Climate feature in the dropdown menu.

<figure><img src="/files/lIuhp7mZRoid6VPNTyTD" alt=""><figcaption></figcaption></figure>

Climate lets you load an EPW weather file and quickly explore your local climate using a range of visualisation and analysis tools. Simply drag and drop an EPW file, or choose one from your local drive, and you'll have access to thermal comfort analysis, wind and moisture insights, and much more.

## Load your climate file

Once you load an EPW file, we'll automatically perform a quality review of the climate data. You can find the results under the **Review** tab, where you'll get a quick assessment of the file before diving into the analysis.

If you'd like to inspect the raw data, head over to the **Table** tab to view all of the information contained in your climate file.

## Explore the climate

From there, it's up to you.

### Heat Maps

The Heat Maps view gives you an easy way to explore annual climate patterns, including:

* Dry-bulb temperature
* Global, direct and diffuse solar radiation
* Humidity
* Wind
* Precipitation
* Thermal comfort

It's a great way to quickly understand how conditions vary throughout the year.

### Degree Days

Jump into Degree Days to explore heating and cooling degree day profiles using different base temperatures. This makes it easy to understand the heating and cooling demands of your climate.

### Psychrometric

<figure><img src="/files/IO3T4sSVmnERO6Pk3N64" alt=""><figcaption></figcaption></figure>

The Psychrometric view plots your climate data against several well-known comfort models, including:

* ASHRAE 55
* Givoni
* PMV

This helps you understand how local climate conditions relate to recognised thermal comfort envelopes.

### Comfort

<figure><img src="/files/337ccjCH7MICt7p0vPxp" alt=""><figcaption></figcaption></figure>

The Comfort section brings together several comfort models, including ASHRAE 55, EN 16798, and PMV, so you can explore:

* Annual comfort hours
* Natural ventilation potential
* Comfort by hour
* Adaptive comfort bands
* Daily calendar views

These views make it easy to understand when and how often conditions fall within comfortable ranges.

### Sky Conditions

<figure><img src="/files/Op3s4FtpVpGX9OqnXKJr" alt=""><figcaption></figcaption></figure>

Use Sky Conditions to explore annual sky distributions and sky illuminance. These visualisations provide a better understanding of the daylight conditions that may influence your design.

### Drying Potential

<figure><img src="/files/tguFV7i7zOgu9YbmwtiM" alt=""><figcaption></figcaption></figure>

The Drying Potential tool helps answer an important hydrothermal modelling question: *Which wall orientation is the most critical from a drying perspective?*

This can help you make more informed decisions when assessing moisture performance.

### Interior Climate

<figure><img src="/files/hP1EFcDpNsWRuh9Mytg2" alt=""><figcaption></figcaption></figure>

Finally, Interior Climate lets you explore a range of indoor climate conditions that you may want to use as boundary conditions for hydrothermal modelling.

## We're just getting started

There's already plenty to explore, and this feature will continue to grow over time.

If you have ideas, suggestions, or features you'd like to see, we'd love to hear from you. Simply use the Support button in the top-right corner of the application to raise a ticket. Your feedback will help us shape future updates and make the Climate tools even more useful.

# 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://docs.betterbuilding.io/sign-up-and-plans/news-and-updates/2026/new-climate-feature.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.
