Step-by-Step Guide to Climate Consultant Software Installation and Setup (2025)

1. Introduction: Why Climate Consultant Matters in Architecture

Designing climate-responsive buildings starts with understanding the environment you’re building in. Climate Consultant is a free, graphic-based tool developed by UCLA that translates complex weather data into clear visual insights.

For architecture students and designers, this tool is a bridge between data and design. It turns temperature, humidity, and solar radiation into simple charts and strategies you can actually use — for passive cooling, daylight design, and thermal comfort analysis.

Before we dive into the Climate Consultant software installation steps, let’s first understand what makes it so valuable in your design workflow.

2. Understanding Climate Consultant and EPW Weather Data

Climate Consultant uses something called EPW (EnergyPlus Weather) data — a standardized file format that contains 8760 hours of weather data per year. Each EPW file corresponds to a specific city or region, provided free by the U.S. Department of Energy.

Think of it as a digital weather diary that records everything from temperature to wind speed, hour by hour. The software reads this file and converts it into more than 60 types of climate graphics, helping architects visualize:

Annual temperature swings
Wind rose and ventilation potential
Solar radiation and shading needs
Comfort zone patterns

Having the right EPW file is crucial. It ensures that your simulation reflects the real climate of your site — whether it’s humid Chennai, cool Bangalore, or arid Jaipur.

3. What You Need Before Installing Climate Consultant

Before you begin the installation, make sure your system is ready. The software is lightweight, but it works best on Windows-based systems.

Here’s what you’ll need:

A Windows 10 or 11 computer (it also runs on older versions).
Stable internet connection (for EPW downloads).
Around 200 MB of free space.

You can download Climate Consultant directly from its trusted source:
👉 https://climate-consultant.informer.com/download/

Once downloaded, locate the installer file — usually in your Downloads folder.

4. Step-by-Step Guide: Installing Climate Consultant Software

Now let’s walk through the installation process carefully. Even though it’s simple, many first-time users miss small steps that cause later errors.

Open the Installer File: Double-click the downloaded Climate Consultant .exe file.
Click “Install”: The installation wizard will launch.
Click “Next” a few times: The setup will guide you through the terms and installation folder.
Click “Finish” when done: The software will install in less than a minute.
Open Climate Consultant: Once installed, find it in your Start menu or Desktop shortcut.

Click Install

Click next

You’ll now see the main interface — a clean screen with menus to start a new project, select weather data, and explore charts.

5. Creating a New Project in Climate Consultant

Once the software opens, you’re ready to create your first project.

Click “Start a New Project.”
You’ll be prompted to select:

Project Type: Choose Residential, Commercial, or Academic.
Units: Metric or Imperial.
Weather Data Source: You can either open an existing EPW file or install new weather data.

For most users, choosing Metric makes sense, especially in architecture schools and professional studios across India and Europe.

Once this is set, click Next to proceed to weather data selection.

Start a New project

Select the project type, Units & weather Date

6. Installing EPW Weather Data for Your Region

This is the most critical step — connecting real-world climate data to your project.

When you click “Open Existing EPW Weather Data File”, you’ll see an option:
“Install from Weather Data Site.”

Clicking it opens the EnergyPlus Weather Data webpage. This is where thousands of EPW files are stored, categorized by region and country.

Here’s how to set it up:

Select Your Region: Choose Asia, North America, or your relevant region.
Select Your Country: For example, India.
Find Your City: A list of cities will appear (e.g., Chennai, Delhi, Mumbai).
Right-click on your city’s EPW file and select “Copy Link Address.”
Return to Climate Consultant and paste the copied link into the Install Weather Data window.

Click “OK”, and the software will automatically download and install the weather data.

With respect to Weather data can select Open Existing EPW weather Data file - to get the climate data specific to your region.

How can we install this Data for a specific region ? Lets see how?

When this Tab - Open Existing EPW weather Data file - is clicked

It will direct to the following screen to Install Weather Data

When you click Install from Weather data site it will direct you to Energyplus site shown below.

Click on the specific Region it will direct to respective countries under the region and on selecting the country will list the cities EPW Weather Data.

Right Click on the EPW file of the city - Copy Link address

Paste the link in the Install Weather Data window.

Now Installation process of Climate consultant and Setting up a New project with its own EPW weather data is completed.

Once done, Climate Consultant will display your city name and climate data summary at the top of the interface. You’re now ready to explore!

7. Exploring Climate Charts and Design Strategies

After installation, the most exciting part begins — visualizing your local climate.

Climate Consultant automatically converts your EPW data into over 60 types of charts, including:

Monthly temperature and humidity profiles
Wind rose diagrams
Sun path and solar radiation graphs
Comfort zone analysis (based on ASHRAE standards)

Each chart provides insight into how your building should respond to the local climate. For example, high solar radiation graphs may suggest shading or reflective roofing strategies, while humidity curves indicate ventilation needs.

Design students can use these visuals to support climate-responsive design concepts and early-stage energy modeling.

8. Common Issues During Installation (and How to Fix Them)

Even though the installation is simple, small issues can occur — especially with EPW links or system settings.

Problem 1: “EPW File Not Found” Error
This usually means the copied link is incorrect or broken. Go back to the EnergyPlus site and copy the link again carefully.

Problem 2: “File Path” Error During Setup
Avoid installing the software in deeply nested folders. Keep it under the default directory (like C:\Program Files).

Problem 3: Software Doesn’t Open After Installation
Run it as an administrator or reinstall it using the default settings.

Problem 4: EPW File Won’t Load Properly
Ensure your internet connection is active during the “Install Weather Data” step.

Keeping these fixes in mind will help you avoid setup frustration and get straight to design analysis.

9. Tips for Using Climate Consultant Effectively

Once you’ve completed your Climate Consultant software installation, explore its full potential.

Here’s how to make the most of it:

Study the Comfort Chart: Understand what percentage of time your city’s climate falls in the comfort zone.
Check Wind Patterns: Use wind rose data to decide natural ventilation strategies.
Look at Sun Path Diagrams: Perfect for orientation and shading design.
Compare Design Alternatives: Export charts and compare results between multiple locations or design proposals.

For professional users, Climate Consultant can be integrated conceptually with tools like SketchUp, EnergyPlus, or Ladybug Tools for deeper analysis.

10. Climate Consultant vs Other Climate Analysis Tools

While Climate Consultant is simple and free, it’s not the only tool in this domain. Let’s understand where it stands.

Ladybug Tools (Grasshopper Plug-in): More detailed simulations, but requires Rhino and scripting skills.
Climate Studio: Commercial software with advanced daylight and thermal modeling.
Autodesk Insight: Focuses on building energy simulations with BIM integration.

Climate Consultant stands out because of its ease of use. It’s perfect for early-stage concept design — ideal for architecture students, educators, and professionals who need quick, visual feedback rather than full simulations.
