Welcome to our calculation tool for air handling units (AHU). This web-based tool calculates the annual energy demand and the life cycle costs of an AHU to provide the supply of air. With just a few input data, you will receive the annual energy demand as well as the annual costs and life cycle costs for a configurable AHU. The tool calculates the ideal, minimum energy demand based on hourly resolved weather data, which is necessary to achieve the thermal comfort conditions in the building. In addition, you can view the hourly resolved power of the AHU’s components and thus get an overview of their maximum design power and their temporal distribution of the partial load states.

You can access the tool via https://ahulife.eonerc.rwth-aachen.de.
