CLAY BRICK WALLINGS, BUILT-IN CLIMATE CONTROL DUE TO HIGH BULK DENSITY
Brickwork, by the virtue of its high bulk density, has a corresponding large thermal capacity, with the ability to absorb and store a significant quantity of heat during peroids of daytime, increasing temperature, and to isolate this heat in a controlled manner during periods of right time decreasing temperature.
Under most South African climate conditions, solar energy is available to heat up the external walls of a brick dwelling during the day, storing a considerable amount of heat energy which is later released into the interior of the dwelling during the night. As a result of this thermal fly wheel effect, interior temperatures are contained within comfortable upper limits during warm weather and prevented from dropping to uncomfortably cold values during winter nights. Heavyweight brickwork has the benefit of reducing internal temperature fluctuations both daily and seasonally, whereas lightweight walls lead to large and uncomfortable swings in internal temperatures as demonstrated by Fig. 1 for summer conditions in the Highveld (Pretoria).
