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 ...

Using thermal mass for heating and cooling Smarter Homes

Concrete slab floors should be 100–200mm thick for the best performance, while thermal mass walls should be 100–150mm thick. Very thick thermal mass walls and floors may take too long to heat, while those that are too thin won't store enough heat.

How to Calculate Heat Capacity of Concrete eHow

A large concrete slab floor can moderate temperatures in the rest of the building. Multiply the mass by the specific heat capacity of concrete, 0.2 BTU/lb/degree F. This yields 0.2 times 13,300 equals 2,660 BTUs to raise the temperature of the entire wall just 1 degree Fahrenheit. Advertisement.

Thermal mass - Wikipedia

Thermal mass for limiting summertime overheating. Thermal mass is ideally placed within a building where it is shielded from direct solar gain but exposed to the building occupants. It is therefore most commonly associated with solid concrete floor slabs in naturally ventilated or low-energy mechanically ventilated buildings where the concrete soffit is left exposed to the occupied space.

Thermal mass - Energy Education

Thermal mass refers to the material inside a building that can help reduce the temperature fluctuations throughout the course of the day; thus reducing the heating and cooling demand of the building itself. Thermal mass materials achieve this effect by absorbing heat during periods of high solar insolation, and releasing heat when the surrounding air begins to cool.

Water: The Ideal Thermal Mass Browning Day

Specific Heat . Specific heat is defined as the amount of heat (BTUs) required to raise the temperature of one unit (i.e., one pound) of mass one degree of temperature (°F).. Water needs over four times more heat to rise in temperature than either concrete or brick (Fig. 2). This means that water has the capacity to “absorb” more heat than other typical types of thermal mass.
