### 1.1.1. Program possibilities

Program can perform following calculations of:

- overall heat-transfer coefficient "U” (or heat resistance „R”) of building partitions,

- control of dew-point on internal surface of external partitions,

- control of condensation inside of external partitions (by Glaser’s method),

- heat losses in compartments and entire building,

- balance of ventilation air for flats,

- seasonal energy demand for heating purposes and „E”-indicator,

- air temperature in non-heated compartments on the basis of thermal balance,

- selection of unit heaters of water central heating system.

Norms, on which the calculations are based, depend on the program version (its destination for specified market). Specification of these norms for individual version has been described in Appendix B. Applied norms and calculation methods.

Thanks to possibility of work with files common with Instal-therm program, after completion of some data it is possible to calculate the heat losses in buildings. The plan views of these buildings are available in DWG or DXF files; it is not necessary to enter manually the dimension of cooling partitions into program tables.
