Audytor HL

Building 3D modelling and heat load calculations.

Software designed for 3D computer modelling of buildings, as well as for computer aided calculations of heat load of individual rooms.

The program calculates (depending on the language 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
  • radiators selection

Easy input of your design data into the computer

User's friendly 3D design editor assists designers in effective and fast data input.



Easy computer modelling of storeys of buildings

Thanks to the functionality of entering building base drawings, users can draw walls, windows, doors and floors with no requirement of precise manual dimensioning of all these components. Import of building base drawings is possible from DWG files, bitmaps or directly from scanning devices



Correctness check of the model


After 3D computer models of buildings have been created, designers can perform correctness check of entered building partitions.



Time saving

The concepts of data inheritance and default data will save users time and effort when entering individual building components.



Option for fast modification of parameters

Application of variables enables performing variant calculations.



Preliminary selection of radiators

Already at the stage of designing buildings, designers can assess the required dimensions of radiators in heating systems.



Assistance in preparation of technical documentation

Designers can prepare technical documentation for projects, basing on extensive overviews of materials, building partitions and selected radiators.





Import of the building model from Revit 2016 - 2018- 2018

The function allows you to import a building model from Revit 2016 - 2018. Revit has the ability to export a building model to the gbXML format. In order for the gbXML file to be properly adapted to the Audytor HL, you should use Audytor gbXML - the Revit plugin. Depending on the amount of data entered in Revit, the model may be almost full after the transfer. In the Audytor HL, only the data on the functions of rooms and the grouping of rooms can be supplemented. The imported building model can be verified using a three-dimensional preview.
