Greenhouse/CO₂ recycling

The glass shell creates room on the roof for a greenhouse, which will accommodate a botanical garden and a school garden. The CO₂ produced by the building will be transferred to the greenhouse via the buffer areas, at which point it will be absorbed by the plants. A glass shaft leading from the parking garage under the building to the greenhouse on the roof will create a strong ventilation flow. There will be plants in this shaft, and the air from the parking garage will be led past these plants and purified with regard to CO₂ and airborne particulate matter. In order to absorb enough CO₂, part of the greenhouse will be a high-production facility. This will result in a CO₂ cycle. In the high-production section of the greenhouse in particular, there will be a lot of waste plant matter. This can be used as biomatter for the co-fermentation plant.
