Audytor OZC

version 3.0/4.0/4.8/5.0 – this program was designed to support calculations of heat losses for the whole building and its individual parts.

The program calculates (Depending on the version):

  • heat-transfer coefficients for walls, floors, roofs and flat roofs
  • heat losses for individual rooms
  • heat loss for the whole building
  • heat balance for the apartment building heating period
  • energy performance certificate
  • annual energy consumption
  • radiators selection (nearly 25 000 items)



Short description

  • entering data in a table- and window-form
  • automatic suggestion system and validation of the entered data
  • a vast catalogue of building materials
  • the radiator catalogue contains a complete manufacturer documentation, organised in tree forms of the pdf browser.
  • a possibility of entering data and using it to specify length, area, k coefficient value, temperature and ventilation air stream capacity
  • a possibility of preliminary radiator selection for the rooms
  • a possibility of entering and saving the calculation results to Audytor CO
