Details on Variables
Information about the variables in the Master Tables operating range.
Values which are used frequently can be stored in variables. The corresponding variable can then be used instead of the absolute values. If a change is required, a variable has to be adjusted centrally at this point. You can create your own variables. The variable name (e.g. IW4 for the interior wall in the fourth line of the standard areas for interior walls) is automatically assigned to each new entry.

Variables (Height, Temperatures...)
In the Area Variables (Heights, Temperatures) the following variables are available:
| Name | Variable | Description |
|---|---|---|
| Ceiling thicknesses | D1 to D99 | List of ceiling thicknesses that can be used in the general data in the storey and room level. |
| Heights | H1 to H99 | List of heights that can be used in the room components and general data in the storey and room level. |
| Psi-values | P1 to P99 | List of length-related transmittance coefficients that can be used for the calculation of the thermal bridge supplement. |
| Temperatures | T1 to T99 | List of room inside temperatures that can be used in heat and cooling load calculations. |
| Additional loads | Z1 to Z99 | Additional heat loads such as a refrigerated counter. For the heat load calculation, a heat supply must be specified as a negative value, heat dissipation accordingly as a positive value. |
| Grades of energy transparency | G1 to G99 | List of grade of energy transmittances for glass/transparent thermal insulation (g-value) that can be used in the window configuration for cooling load calculation. |
| Thermal bridge supplements | W1 to W99 | List of thermal bridge supplements that can be used in the heat load calculation for room components. |
| R-value | R1 to R99 | List of heat conduct resistances of surfaces; can be used in radiant heating and cooling for the calculation of the heat conduct resistance of an activated component. |
Standard Areas
When defining areas, the following applies in principle: Parameters left open (e.g. the width) can be adjusted manually in the heat or cooling load calculation. Parameters set in this table cannot be edited in the heat load calculation. Geometric dimensions and U-values can be defined for all surfaces, for some areas (with glass) there are also energy transmittance values. The following variables are available:
| Name | Variable |
|---|---|
| Exterior Windows | AF01 to AF100 |
| Exterior doors | AT01 to AT100 |
| Exterior wall | AW01 to AW100 |
| Roofs | DA01 to DA100 |
| Interior Windows | IF01 to IF100 |
| Interior doors | IT01 to IT100 |
| Interior walls | IW01 to IW100 |
| Floors | FB01 to FB100 |
| Ceilings | DE01 to DE100 |
| Roof Window | DF01 to DF100 |
| Deduction areas (areas for which no transmission heating demand is to be taken into account). | ABF01 to ABF100 |
