2.4.2 Water wall

A water wall is a system that works similarly to Trombe walls. The water wall is a non-loadbearing wall made from water tanks or water silos located on the solar-access sunny, which is the northern façade of a building in South Africa. The water is subject to convection during heating, causing the system to conduct the heat more rapidly than a Trombe wall system with a much higher thermal lag (Figure 7) (Gut & Ackerknecht 1993).
