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)

Thermal Resistance & Thermal Conductance C-Therm

Thermal conductance is the time rate of steady state heat flow through a unit area of a material or construction induced by a unit temperature difference between the body surfaces, in W/m2⋅K. C-value, hence, is the reciprocal of the R-value and can be expressed as Equation (3). Consequently, the value of the thermal conductance can be
