Thermal Mass of Concrete Concrete Construction Magazine

Thermal mass relates to the ability of a material to store and release heat. All materials have thermal mass. However, because concrete is used in large amounts in buildings, these buildings have greater total thermal mass than most buildings made with competitive materials. The concrete and masonry industries, based on research they have done ...

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 ...

Thermal Inertia of Concrete Concrete Construction Magazine

Thermal inertia, the ability of a building to store heat over a span of time and release it slowly as temperature drops, plays an important part in designing buildings to be energy efficient. The Portland Cement Association studied three hypothetical buildings: all concrete, all metal and concrete walls with metal roof. The study was repeated for each of 10 cities selected for their range of ...

Concrete and heat transfer Concrete Construction Magazine

01/10/2004  The resistance of a material to conduct heat energy from one surface to another is its thermal resistivity, which for a given area is expressed on a per-unit-thickness basis. For what you describe, a workable resistivity would be 0.09 hr ft2 deg. F/Btu in. Multiplying that per-inch value times the thickness of the concrete would give you an R-value for the concrete. Assuming a 6-inch wall ...

GreenSpec: Thermal Performance: Thermal Mass in Buildings

SAP and thermal mass. SAP 2009 uses thermal mass in calculating the heating and cooling load of the building. SAP uses the kappa (k) value to determine thermal mass. 'k' is the measure of the heat capacity per unit area in kJ/m 2 K of the 'thermally active' part of the construction element:. k = 10-6 Σ i p i c i d i. p i = the density of the layer 'i' in the construction (kg/m 3)

17/06/2020  Insulated concrete formwork (ICF) walling also provides a good thermal store, since it consists of mass concrete encapsulated in a thick layer of insulation. The concrete core absorbs and stores heat, acting as a buffer. In combination with the surrounding insulation, this reduces temperature fluctuations – although it is slightly less effective overall than exposing a blockwork wall internally.
