Validation according to EN ISO 10211:2007
The program package AnTherm fulfils all requirements raised in EN ISO 10211:2007
for the simulation program to qualify it as two and threedimensional,
stationary precise method
(„Class A – Method“).
The
EN ISO 10211 "Thermal bridges in building construction — Heat flows and
surface temperatures — Detailed calculations" in its appendix A
provides the validation procedure by which a "thermal bridges program"
must conform to, to be qualified as "high precision method". The application
package AnTherm conforms in its current version to all respective criteria
specified by EN ISO 10211:2007 for "high precision calculation methods" and thus
it qualifies as "two and threedimensional steadystate high precision method
(class A method)"
Details of validation and benchmark results are put together
the calculation report
of validation examples from the EN ISO
10211:2007 by the application package Antherm.

Reference case 1 (twodimensional; temperature distribution
within "half of a square column")
By the precision set within the standard (1 decimal place after comma)
AnTherm provides exactly concordant results. By concerning
uncertainties resulting from rounding there is full concordance of
results calculated by AnTherm with values calculated analytically.

Reference case 2 (twodimensional; temperature distribution
and heat flow within a roof construction)
This reference is considered shaky due to the temperature and heat flow
calculation requirement within the junction made of a aluminium bracket nested
within insulating material.
By concerning uncertainties resulting from rounding there is full concordance
of results calculated by AnTherm with values set in EN ISO 10211:2007.

Reference case 3 (threedimensional; temperature distribution
and heat flows through the wallbalcony junction)
By concerning uncertainties resulting from rounding there is full concordance
of results calculated by AnTherm with values set in EN ISO 10211:2007.
The difference between heat losses of interior spaces α and β and gains of the
exterior (space α) calculated by AnTherm and those specified by
EN ISO 10211:2007 are smaller than 0.11 %. The requirement set in EN ISO 10211,
that differences of calculated heat flow values must not exceed 1%, is met by AnTherm
in full.

Reference case 4 (threedimensional; temperature distribution
and
heat flows within a three dimensional thermal bridge consisting of an iron bar
penetrating an insulation layer)
By concerning uncertainties resulting from rounding there is full concordance
of results calculated by AnTherm with values set in EN ISO 10211:2007
The difference of 0.43% between the calculated heat flow and the value set by
the standard is below the allowed tolerance of 1% as required by the reference
case; The temperature calculated at the hottest point at exterior surface
deviates by 0.003K
which is below the tolerance of 0.005K set by the standard for that reference
case; the criteria are met in full by AnTherm.
