Sustainability
This house is sustainable, due to the use of bamboo for the structure and for the coverings of walls, floors, ceilings and the roof.
Because of the use of bamboo on the roof, ceilings and walls, the shape of the house (the large eaves prevent the walls from heating up) and the cross-ventilation due to the location of the windows, there is a pleasant climate inside the house.
Bamboo grows fast and is CO2 neutral. The construction of this bamboo house is an effective remedy against the climate change.
Concrete Base
12 reinforced concrete footings (100x100x25 cm), with Ø12 mm steel reinforcement (2x 10x10 cm mesh).
12 columns for the bamboo structure: (32×32 cm, height 100 cm, reinforced concrete with Ø12 mm steel reinforcement (8 Ø12 mm rods, total 904 mm2 column shear steel, 0.88%). The visible part of the columns will be plastered.
12 reinforced concrete beams (24×36 cm, total 60 m of concrete beams), with Ø12 mm steel reinforcement (6 Ø12 mm rods, total 678 mm2 beam shear steel, 0.78%).
Reinforced concrete floor, 10 cm, with Ø10 mm steel reinforcement mesh, 18.75×18.75 cm.
