Thermal mass of concrete

Concrete has a high thermal mass with properties similar to brick and stone. It is possible to absorb heat from the atmosphere in warm weather and release it during cooler periods, e.g. overnight. This is known as the ‘thermal flywheel’ effect. In a passive concrete design the cooling capacity of concrete can be up to 25W/m 2 and with an ...
