Project Goals

Produce 200% of the energy needed by the building itself

Predictive and self-learning building control system

Linking energy flows of the Building, the E-Cars and the District

Create Prototype as a source of innovation for the Planning
Process and for Building Technologies
Building Site: Bruckmannweg 10
Definition: Aktivhaus®

Buildings, that individually or within a network, produce more energy
than they need for themselves

Buildings that actively respond to changes of the energy performance
or comfort of the users

Buildings that form a self-organizing network with other buildings,
energy providers, energy storage and energy consumers following
the broad objective of energy self-sufficiency
