WebA Psi-Value or ψ-value is a measurement used to determine the rate of heat loss through a junction (where two thermal elements meet e.g. external walls and ground floor). The heat loss (measued in W/mK) at these junctions is refered to as non-repeating thermal bridges. These can provide up to 25% of the total fabric heat loss of a building.

WebThe attic construction shows a strong thermal bridging effect. There is a heat loss of 0.4 watts per meter of construction and degree Celsisus. Assuming a temperature difference of 30 °C and a surrounding attic with a total length of 32 m would therefore cause a heat loss of approx. 400W. Thermal Bridge – Attic example – Temperature view WebThe Psi-Value Calculator is used for rapid calculation of the linear thermal transmittance of the thermal heat bridge (correction factors Psi (Ψ, L Ψ, ) resulting from the input of U-values and lengths specific to the building component concerned and its thermal coupling coefficient L 2D as calculated within a steady state, two dimensional …

WebJan 3, 2014 · In many thermal bridge computations, you can choose the reference point against which to calculate the linear thermal transmittance (psi). The most common example is the edge of a building: It is possible to calculate psi compared to the internal reference point (lengths A and B) or outside (C and D). Thanks to Mold Simulator 3’s new … WebThe extra heat loss at a thermal bridging is measured by way of its linear thermal transmittance or Psi (Ψ) value in units of (W/mK).
