Hamburg, Germany. Consisting of micro-algae integrated into the walls, bio-adaptive facades allow a building to access a certain energy autonomy.
How? Through photosynthesis and recycling of solar energy. Algae are fed continuously with liquid nutrients and carbon dioxide via an independent water circuit that flows through the facade. It is an integrated bio-reactor that supplies heat to the fifteen apartments in the building.
"The heat is produced on this façade by bioreactors and is then sent to a power station. The heat is stored and then redistributed and used in a heating circuit to heat the building and its drinking water, "explains Martin Kerner, project manager.
This seaweed building therefore produces its own heating. Laura is one of the tenants. Its balcony looks like an aquarium filled with algae that reproduce regularly. This building is a so-called "passive" building, that is to say a construction guaranteeing a comfortable indoor climate without heating system, which also saves money.
"I believe that this energy saving represents about a gain of 1000 euro per year because we pay almost nothing now because it is a passive building and very well isolated," Laura said.
To prepare for winter, the building even keeps the heat produced during the summer underground. This heat can therefore be reused a few months later. This innovative concept is an alternative to the construction of ecological habitat of the future.
"This is a vision for the future and it is an answer to the questions we had already asked ourselves 30 years ago," explains Dietmar Walbert, architect.
This building was specially designed for the International Building Exhibition, which runs until 3 next November in Hamburg.
