The Heating Degree Days (HDD) method is an essential tool for energy management in buildings. It measures the energy demand for heating based on temperature variations. This article explains the HDD method in detail and how Enectiva simplifies its use by automatically calculating HDDs using local weather station data and configurable internal parameters.
What is the Heating Degree Days Method?
The Heating Degree Days method is used to estimate a building’s heating needs. It is based on the difference between the daily average outside temperature and a reference temperature, often called the “base temperature.” The lower the outside temperature compared to the base temperature, the higher the number of heating degree days.
How to Calculate Heating Degree Days?
The calculation of HDD is straightforward:
- Define the base temperature (e.g., 18°C).
- For each day, subtract the average outside temperature from the base temperature.
- If the result is positive, it represents the heating degree days for that day. If the result is negative then the HDD for that day is 0.

In this example, the number of HDD for these 4 days is 17.
Benefits of Using Enectiva for HDD
Enectiva simplifies this process by automating HDD calculations. Here’s how:
- Local Weather Data: Enectiva integrates data from local weather stations for accurate calculations.
- Configurable Parameters: Users can set the base temperature and other parameters according to their building’s specific needs.
- Detailed Reports and Analysis: Enectiva provides comprehensive reports and analysis for optimal energy management.
The Heating Degree Days method is a powerful tool for energy management. By using Enectiva, building managers can easily calculate and analyze HDDs to improve energy efficiency.
