AnTherm (Analysis of Thermal behavior of Building
Constructions with Heat Bridges) is a powerful program used for heat flow calculation
in building construction elements - the thermal
heat bridges and vapor bridges.
Thermal Bridge Assessment can be executed easily, quickly and precisely with AnTherm.
This Thermal Heat / Cold Bridge Simulation Software calculates the
distribution of temperature, heat streams and vapor
diffusion streams within building components of arbitrary form
and built as composite of arbitrary materials. Furthermore AnTherm
can compute and evaluate the dew point values (condensing
humidity) at all component surfaces as well as partial vapor
pressure in components interior. This application is also
suitable for analyzing dynamic behavior of building
components (for periodic, harmonic,
transient boundary conditions).
For the technically qualified designer, AnTherm is a reliable,
tool in meeting the demands of the current standards (ISO, EN, ...) for
evaluating thermal performance thoroughly and precisely.
The detailed analysis of thermal bridges for passive house planning, energy efficiency assessment or
certification need not be complex nor sophisticated today.
The thermal heat bridge (cold bridge) can be modeled in 2D or
and three dimensional stationary (steady state) and
transient (harmonic, periodic) heat flow

AnTherm is a powerful program package for the calculation of
temperature distributions and heat flows in building structures - particularly
such with thermal heat bridges (cold bridges). For the technically qualified designer, AnTherm
is a reliable, indispensable tool in meeting the demands of the current
standards (EN) for evaluating thermal performance thoroughly and precisely.
Computational capabilities of the thermal bridge software
AnTherm include, amongst others:
applicable and suitable with very detailed components (e.g.
facades, window frames, ...) and for very large, extensive
calculation cases (e.g. components in contact with ground,
whole space envelopes, groups of spaces, ...)
calculation and visualization of the distribution of relative
condensing humidity at all surfaces
calculation of the field of partial vapor pressureand,
having the difference built to saturation pressure easy
identification of core condensation risk within the component (with
It shall be emphasized, that Prof. Dr. Krec, one of the
fathers of the concept of "thermal conductance coefficients",
has not only been
continuously involved at the development of
AnTherm and took part in decision making and verification of
the software, but also stands by, by phone, in case of questions and conversation
