English: The Cooling effect of the Riad Laksiba Courtyard is no accident. Design: A water feature at the base of a Riad courtyard serves two purposes. Firstly, the obvious focal point but more importantly, the courtyards oper-air aperture channels warm air entering into the Riad which inturn passes over the water feature, cools down, thus assisting in the convection of heat to exit back through the Riad's open-air aperture. This style of natural air-conditioning has been prevelent in Morocco for millenia and is remarkably sucessful.
