Biosol is a concept of ecological design of a residential building and community living that creates favorable microclimate conditions for different types of plants in green areas and walls using energy from solar panels. The building works as an ecological community in which all tenants are involved. It consists of a folded solar panel in the origami model that can be inserted into the walls of the building, green areas for the controlled introduction of new species, an interactive book that talks about the plants that are there by touch, a box for seedlings by agreement of the community.
