Support tools and information for designing and application
|Calculations of energy performance, i.e. solar gains and thermal losses on a monthly basis, can be done on the basis of
German and European standards (e.g. for the German energy-performance regulation EnEV 2002 and EnEV 2006).
We support planners and engineers with the following calculation tools to prepare the input data for the standard building energy
performance calculation tools. If no special TI-option is available in the building performance tool, we recommend to model the
solar wall as an "equivalent window", having similarly solar gains and thermal losses.

A special tool is available for the German standard DIN 4108 part 6, where the solar wall heating system using TI implies separate procedures. Not every commercial software has this option implemented, however it is nevertheless possible to described the system as an opaque element. However, the input data needed are not intuitive and not easy to find. Therefore we have prepared a special conversion tool for this procedure. Generally the option "equivalent window" is much easier to understand and to use.
