Thermal Bridge Heat Transfer & Vapour Diffusion Simulation Program AnTherm Version 6.115 - 8.132 

[ ← ] [ ↑ ] [ → ] [ToC]

Validation according to EN ISO 10077-2:2003

The program package AnTherm fulfils all requirements raised in EN ISO 10077-2:2003 for the simulation program to qualify it as standard method for calculation of heat flow through frames of windows, doors and shutters.

The EN ISO 10077-2:2003 "Thermal performance of windows, doors and shutters - Calculation of thermal transmittance - Part 2: Numerical method for frames" in its appendix D provides the validation procedure by which a "thermal bridges program" must conform to, to be qualified as sufficient for the calculation of heat flow through frames conformant to the standards. The application package AnTherm conforms in its current version to all respective criteria and assessments specified by EN ISO 10077-2:2003 and thus it can be used as "standard method for calculation of heat flow through frames of windows, doors and shutters"

Detailed validation and benchmark results are put collectively into the calculation report of validation examples from the EN ISO 10077-2:2003 with the application package Antherm.

  • Reference cases 1 through 7 (thermal conductance Lf2D and thermal transmittance Uf of frame profiles)
    By concerning uncertainties resulting from rounding there is full concordance of results calculated by AnTherm with values set in EN ISO 10077-2:2003.
    The differences between thermal conductance  Lf2D calculated by AnTherm to those specified in the EN ISO 10077:2003 stay below 1.1%. The requirement set in EN ISO 10077-2, that differences of calculated thermal conductance must not exceed 3.0%, is met by AnTherm in full.
    The differences between thermal transmittance Uf calculated by AnTherm to those specified in the EN ISO 10077:2003 stay below 1.7%. The requirement set in EN ISO 10077-2, that differences of calculated thermal transmittance must not exceed 5.0%, is met by AnTherm in full.
     

  • Reference cases 8 and 9 (thermal conductance Lf2D and transmittance U of profiles)
    By concerning uncertainties resulting from rounding there is full concordance of results calculated by AnTherm with values set in EN ISO 10077-2:2003.
    The differences between thermal conductance  Lf2D calculated by AnTherm to those specified in the EN ISO 10077:2003 stay below 1.2%. The requirement set in EN ISO 10077-2, that differences of calculated thermal conductance must not exceed 3.0%, is met by AnTherm in full.
    The differences between thermal transmittance U calculated by AnTherm to those specified in the EN ISO 10077:2003 stay below 0.5%. The requirement set in EN ISO 10077-2, that differences of calculated thermal transmittance must not exceed 5.0%, is met by AnTherm in full.
     

  • Reference case 10 (thermal conductance Lf2D and linear thermal transmittance Ψ of glazing, spacer and frame compound)
    By concerning uncertainties resulting from rounding there is full concordance of results calculated by AnTherm with values set in EN ISO 10077-2:2003.
    The difference between the thermal conductance  Lf2D calculated by AnTherm to the value specified in the EN ISO 10077:2003 stays below 0.2%. The requirement set in EN ISO 10077-2, that differences of calculated thermal conductance must not exceed 3.0%, is met by AnTherm in full.

    The difference between the linear thermal transmittance Ψ calculated by AnTherm to the value specified in the EN ISO 10077:2003 stays below 2.4%. The requirement set in EN ISO 10077-2, that difference of calculated linear thermal transmittance must not exceed 5.0%, is met by AnTherm in full.
