Details on Variables

Information about the variables in the Master Tables operating range.

Frequently used values 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 folder 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. The variable is to be entered at room level for the column in which the additional load should take effect.

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 panel heating/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:
