Traditional buildings in Indonesia make use of ‘passive’ cooling techniques.
Being well ventilated, raised off the ground, and with shady verandas, their design allows them to stay cool in a tropical climate without air conditioning. The classic timber ‘Queenslander’ house also follows a similar design.
Now architects and engineers from both countries are getting together to compare notes on such designs and materials in a collaborative project funded by the Australia-Indonesia Centre.
One of the biggest problems is incorporating these design features into high density urban areas. But housing construction in very high density urban areas is needed, says Jatmika Suryabrata of Universitas Gadjah Mada, who is leading the Indonesian end of the project.
Much of this housing is high-rise and a huge amount of this sort of construction is planned in coming years.
“Cross-ventilation in these buildings is a challenge. So creating more porous building masses for low income vertical housing will be critical. And ceiling fans could significantly improve thermal comfort,” Jatmika says.
