AnTherm (Analysis of Thermal behavior of Building Constructions with Thermal Bridges and Vapour Diffusion)

Share this Post:

This Thermal Heat / Cold Bridge Simulation Software calculates the distribution of temperature, heat streams and vapor diffusion streams within building components of arbitrary form built as composite of arbitrary materials. Furthermore AnTherm can compute end evaluate the dew point values (condensing humidity) at all component surfaces as well as partial vapor pressure in components interior. For the technically qualified designer, AnTherm is a reliable, indispensable tool in meeting the demands of the current European standards (EN ISO) for evaluating thermal performance thoroughly and precisely.

AnTherm provides totally new capabilities for evaluating building envelope elements or even whole buildings with particular attention to thermal bridges and (optionally) vapour diffusion. It provides modern three dimensional visualization functionality speeding up the complex evaluation process in terms of qualitative research followed by quantitative (numerical) analysis of results.

It is validated as “two- and three dimensional precision method” conformant with EN ISO 10211 and EN ISO 10077.

AnTherm can provide significant value (being a really valuable tool) to daily thermal bridges, energy performance and building quality evaluation work.

The lately added extension to AnTherm allows 2- und 3-dimensional analysis of dynamic, transient problems while considering heat capacity and storage processes under an assumption of periodic (harmonic) boundary conditions.
The calculation of harmonic thermal coupling coefficients is accomplished directly, i.e. without the need to know nor to provide any boundary conditions. Results can be used directly by other applications like PHPP.

The added value of this option results from cost effective ability to precisely analyse dynamic heat capacity and storage processes, for example in case of components in contact with ground.
Input of  ρ- and c-values (mass density and specific heat capacity) is available within this option only. Calculating (solving) the dynamic, transient, harmonic equation for typical period lengths of one year and/or one day can be controlled within solver parameters (if the user has the rights to use the transient option).
