Software, Technologies and Building systems

DESCRIPTION:

Danfoss Leanheat Building is an AI-based software and control system used to manage heating at building level. It replaces the traditional approach based on a fixed relationship between heating supply temperature and outdoor temperature, known as weather compensation. Instead, the solution combines an adaptive dynamic building model with weather forecasts and measured indoor temperatures from apartments. This allows the system to estimate the optimal heating supply temperature at any given time while maintaining indoor comfort, taking into account the building’s passive thermal storage capacity as well as solar radiation, wind, and outdoor temperature predictions.

Efficient Operation & Flexibility

VALUE

A qualified setting of the heating supply temperature is critical to reducing uncontrolled heat losses by the building heat distribution system, as well as for reducing the uncontrolled heat emission from the radiators. By applying the Danfoss Leanheat Building AI based control system, the setting is automatically made and optimal all year around. It has proved to reduce the building energy consumption for the heating service, without compromising comfort. Data so far have shown an energy saving of 5-7% for SAB department 22.

APPLICATION

The control of the supply temperature to the building level heating system (radiators and floor heating) is in operation for all 9 building level substations at the SAB department 22 demo building in Sønderborg, Denmark. The concept is available on the market and commercial activities are ongoing. It supports the general trend of digitalisation of the district heating system, and a significant market growth is expected.
