Degree Days
Degree Days are indispensable for the systematic analysis of heating and cooling consumption and the evaluation of optimization measures. The two key figures are decisive basic values for the normalization of Energy Data in the real estate sector and industry. Normalization is performed to correct seasonal weather influences on energy consumption and thus make it comparable across different observation periods and geographical locations, as required by ISO 50001, for example. Our service is therefore primarily aimed at Energy Managers and Energy Experts.
- Do you you monitor and manage the energy performance of your organization?
- Is your organization located at multiple sites?
- Do you need a reliable source for international Heating Degree Days, updated every month or maybe even every day?

Get our energy indicators via an automated interface directly into your EnMS
Energy Data GmbH's database includes decades of records from over 23,000 weather stations worldwide. We obtain the weather observations from the Meteorological Assimilation Data Ingest System (MADIS), and the Integrated Surface Database (ISD). Quality checks by different algorithms of the systems are performed to check for e.g. extreme values and limits, consistency between parameters and continuity between observations.
Via an interface, you can send individual requests to our database and the requested key figures are calculated and made available "live".
What is an API?
The abbreviation API stands for Application Program Interface. APIs are used to exchange data between different systems or programs.
In order to enable data exchange, a special syntax - "language" -is defined in the API.
If want to dig deeper into the technical details check out our API Documentation.
This is to technical for you? Don't worry, we have an easy to use web-interface. Try it out here: Degree Day Calculator PRO
How is the integration into my existing system working?
Any common Energy Management software or database solution is able to make API requests to our server and process the received data into the existing system. Even Excel allows easy integration of our data.
The request is send via a individual URL to our servers. Our software is then calculating your request and send back a file with your energy indicators in CSV format.
