Thermal mass


Thermal mass

A lot of heat energy is required to change the temperature of high-density materials like concrete, bricks, and tiles. They are therefore said to have high thermal mass. Eco designers will strategically place these materials to create heat sinks that absorb heat in the winter and remain cool in the summer. Lightweight materials such as timber have low thermal mass.

Any material or wall that can absorb heat or cold and release it at a later time. Also see roof pond, rock storage, and Trombe wall.
