Safari Roof!
From
The Ho Residence
"With such a wide area being exposed to the sun and heat throughout the day, it was critical that the roof design effectively overcome the issue of solar gain. Interestingly, the design drew its inspiration from Land Rover with its safari roof.
"The safari roof was a device designed for the Series Type Land Rovers operating in the hot tropics. A simple sheet of aluminium mounted on top of the vehicle with metal feet, sandwiched a layer of air for insulation, which, when heated sufficiently, dissipated the air along with the heat while drawing in cool air through a repetitive cycle. More about this later."
