The Help and Info buttons (licence information) are accessible by clicking the small arrow to the right of the Kopnyc menu.

Requirements

In addition to Autodesk Revit, Kopnyc requires the following modelling rules to be observed:

Use Rooms (not Spaces) – Revit Rooms must be used; Spaces are not supported.
Rooms must not be inside Groups – This is due to technical limitations of certain parameter types.
Unique apartment identifier per variant – When using design variants (e.g. accessible versions), each variant of an apartment must have its own unique identifier. If the same identifier is used for multiple variants, all associated rooms will be included in the calculation.
Example: 121 for the standard variant and 121.PMR for the accessible variant.

Note If your file uses Spaces instead of Rooms, you can use the included Dynamo script "Spaces to Rooms" from the Tools / Dynamo Scripts section to automatically convert Spaces into Rooms.

Calculation Method

Kopnyc calculates various area values depending on the project requirements. The table below explains the key terms:

Term	Definition
Total Area	Sum of all rounded room areas assigned to an apartment – including ancillary rooms.
Living Area	Sum of all rounded room areas in an apartment that are not ancillary rooms. Cellars, garages, etc. are excluded.
Reduced Area (Surface abattue)	Rounded area of a room after applying the defined reduction rule (e.g. area deductions applicable to social housing).
Total Reduced Ancillary Area	Sum of all rounded and reduced ancillary room areas in an apartment, according to the defined reduction rule.
Total Social Area	Sum of all areas assigned to an apartment, calculated using the reduced values – relevant for social housing under applicable regulations.

Total Area

The Total Area is the sum of all rounded room areas assigned to an apartment, regardless of whether they are main or ancillary rooms.

Living Area

The Living Area is the sum of all rounded room areas in an apartment that are not ancillary rooms. Ancillary rooms (e.g. cellar, garage, attic) are excluded from this calculation.

Social Housing Areas

Social housing calculations use specific reduction rules. Kopnyc supports three area types for this purpose:

Reduced Area: Individual room area after applying the reduction rule, rounded.
Total Reduced Ancillary Area: Sum of all reduced and rounded ancillary room areas for the apartment.
Total Social Area: Total apartment area calculated using all reduced individual values.
