Thermal mass - Wikipedia

WebThe benefit of thermal mass is shown in this comparison of how heavy and light weight constructions affect internal temperature. In building design, thermal mass is a property of the mass of a building that enables it to store heat and provide inertia against temperature fluctuations. It is sometimes known as the thermal flywheel effect. [1] http://freestudy.co.uk/dynamics/tm%20diagrams.pdf
