Elaboration of a bioclimatic house in the humid tropical region: Case of the town of Douala-Cameroon

Modelling and simulation of a habitat sample lead to a model which the average resultant dry temperature is of 28.30 °C at the peak hours during the periods of occupation of the house. This result is within the acceptable and tolerable thermal comfort zone in humid tropical climate. It thus arises from this study, that housing with the following specifications: cement floor, wall with mixed hollow concrete block and wood plank, and roof with aluminium sheet is thermally well adapted for the Douala climate. Optimization of the thermal behaviour of this housing consists of bringing vegetation around it in order to reduce the thermal loads due to solar heat gain, improving the air replacement and taking into account the thermal inertia of its walls.
