LichtAktiv Haus

LightAktiv Haus is located in Wilhelmsburg, Germany. In it are installed various types of VELUX roof windows. On the model you can see the current balance of each roof window. The immediate energy balance is calculated as being current incident solar energy minus the heat loss through the window. If the energy balance is greater than zero, the window is adding energy to the building. 

The intention of this model is to illustrate the windows' energy balance at this specific moment and thus illustrate how the sun contributes to the energy balance of the building. This contribution is considerable, even on an overcast day, making the window an actual heat source.

For the LichtAktiv Haus project, we applied energy-efficient architecture to a traditional home in the Wilhemsburg district of Hamburg to create a comfortable, modern living space. The house uses solar energy, numerous windows on the façades and roof, and a natural ventilation system, to turn a classic 1950s semi-detached house into a carbon-neutral home of the future. When complete, every room will be bathed in daylight
