The motifs for BAU 2013 – orchids and mushrooms – are a further development in the idea of linking together the world of nature and architecture. As exciting hybrid designs that are part living organism and part innovative building structure, these motifs are a visual metaphor for the future of building, as can be experienced at BAU 2013. The flowers and the fruiting bodies also represent the way advances are continually being made in the building sector, a process towards which BAU makes a significant contribution as a platform for information and inspiration.

Background As the queen of the plant world, the orchid is the epitome of aesthetics and elegance. Its seeds generally cannot germinate without the presence of symbiotic fungi. As such these plants have a direct symbiotic relationship with their environment. Also, many orchids manage to thrive in highly unusual situations – they grow on other plants, mostly trees, and co-exist with them in a mutually beneficial relationship.   Symbolism As such this orchid of the future stands not only for architectural beauty, but also for functionality: for a harmonious energy balance between the built and the natural environment, for example through photovoltaics and new materials. The symbiotic relationship between the orchid and its habitat also symbolises sustainability in renovation and modernisation, through preserving and extending the life of existing buildings.

Background A mushroom is in fact the above-ground fruiting body of a fungus that grows underground. It represents only a small proportion of the whole organism. Fungi are also superb at recycling: together with other organisms they transform organic waste into valuable humus which in turn promotes the growth of other plants.   Symbolism In many ways the mushrooms in the design for BAU 2013 represent the art of building for the future, of adapting perfectly to an environment by employing unusual strategies – for example with the aid of innovative structures and building materials. They also stand for the effective recycling of existing materials such as wood, stone and metal. Depicted growing from a tree, these mushrooms also symbolise the many advantages to be gained from the renovation and modernisation of existing buildings.
