	The term ‘thermal mass’ describes the ability of a material to absorb, store and release heat energy. Thermal mass can be used to even out variations in internal and external conditions, absorbing heat as temperatures rise and releasing it as they fall. In building design, this can useful for evening out and delaying extremes in thermal conditions, stabilising the internal environment and so reducing or eliminating the demand for building services systems. It can be beneficial both during the summer and the winter.		The term ‘thermal mass’ describes the ability of a material to absorb, store and release heat energy.
