### 4.2.4. Unit change buttons

It is possible to select units in program, in which the User will define partitions dimensions, material layers thickness, value of ventilation air streams, heat losses.

The User can change the material layer thickness unit using the key located in column „d” of partitions edition table. An unit appropriate for a project can be selected from an unit pop-up list.

There are following length units available: meters [m], centimetres [cm] and millimetres [mm]. Selection of another unit during work with project will cause automatic recalculation of entered value.

Change of partitions dimensions unit can be also performed by the User by clicking the dimension unit, for example located next to edition fields of partition dimensions.

If the edition field has an unit, which is marked with black colour, it means the possibility of its change. Grey colour means assigning of unit to the field in permanent way.

Calculation results visible in lower part of windows for edition of storeys, flats, compartments and thermal zones can be presented in units selected by the User. For calculated heat losses there are available watt [W] and kilowatt [kW]. Ventilation air stream can be given in [m3/h], [m3/s], [dm3/min], [dm3/s] or [dm3/h]. To switch between units just click the unit button, for example

Moreover it is possible to declare presentation of thermal calculations results for entire building in chosen units. In “General data”, position “Norms and calculations options” on the tab “Calculations units” the calculation results of energy consumptions for a building in MJ, GJ, kWh can be declared. Calculation results of heat losses can be declared in W, MW, kW.

The User can also enter by himself the substitute names (aliases) for units used by the program. He can do it entering in edition fields, for example edition field of partitions length, selected unit. More information concerning entering the unit aliases you can find in chapter 6.3.
