Normalizing energy usage is simple with our Energy Normalizer. No more complex calculations and spending hours on an Excel data sheet.

With a few clicks, you can create and manage different datasets and evaluate them directly in your browser.

Just fill out the form. The tool will do the rest.

Degree days and normalization are common tools for calculating energy savings, but they can be confusing. If you’re new to degree days and normalization, we recommend reading our short step-by-step manual or some basic articles on the subject.

How The Energy Normalizer Works

  1. Enter the main data of your dataset
  2. upload your energy data
  3. choose the parameters for the normalization

Hit the “normalize button” and let the Energy Normalizer do the calculation.

1. Enter the main data of your dataset

  • Project Name: Enter a name for the dataset that will be used throughout the entire project. This should be unique to your project and should not have special characters such as spaces or ‘-‘s in it. If you leave this blank, we will automatically generate a name for your dataset.
  • API Key (optional): Enter your personal API key that was provided to you with the order confirmation email.

Don’t have an API key? As an Energy Data Member, you can use the Energy Normalizer for free and skip this field!

Can’t find your API key? Don’t worry, you can request it here.

  • Location: Choose the weather station closest to the building you are analyzing.

Not sure which station to pick? Check out all available weather stations on this map and enter the address of your location to find the closest ones.

2. Upload your energy data

You can upload your energy data in csv format. Check here for allowed formats.

Enter the unit that is used in your energy dataset, e.g. kWh, m³ or BTU.

Pro Members with an API key can save and load dataset, too.

Note: With the free account you can only normalize energy data from the last and current year. Our premium plans give you access to ten years and more of historical data.

    3. Choose the parameters for the normalization

    In this step you need to choose what kind of energy consumption you are analysing and which kind of energy indicator(s) should be used for normalization:

    • Heating only: Heating Degree Days
    • Cooling only: Colling Degree Days
    • Heating and cooling

    Depending on your choice let us know what kind of base temperature(s) should be used for normalization.

    The last step is to choose the method for the normalization:

    • long-term average normalization
    • base-year normalization
    • efficiency ratio

     If you’re not sure which method is best for you, check out our article on the different normalization methods.

    Hit the “normalize button” and the tool will calculate the weather-corrected energy data and will create a report for you.
