IN FOCUS NOW: The daunting perspective of housing another three billion people until 2050 is now further exacerbated by the fast climate change. Then, also the need for a huge increase in transport capacity, again with another CO2 challenge.

Solar charging canopies supported by bamboo for solar driven buses in rural, off-grid Thailand. As of now, the aluminium profiles used for support, are more expensive than the solar panels themselves.

URBAN MULTI-STORY BAMBOO HOUSING: The great CO2 sink capacity makes fast-growing bamboo an obvious large scale option for construction materials.

Multi-story, because of the never-ending suburban sprawl with more transport nightmares paralyzing the economy. A reasonable multistory urban density could offer synergy effects when turning garbage into energy, sewers into drinking water, structuring public transport corridors.

This concept could become an efficient bamboo component for modular large-scale prefabrication. Built with a standard height in rigs and proving minimal flexure (due to a high Moment of Inertia) it offers a high slab bearing capacity according to a study by KTH.
