DIN 277 is the area calculation standard for Germany and German-speaking countries. The DIN 277 standard included in AutoCAD Architecture 2024 toolset includes the subset of DIN 277 rules described in the following sections:
The space type classifications in DIN 277 are the following:
Space Type_DIN | Definition |
---|---|
A |
|
B |
|
C |
|
Exterior |
|
The net area type classifications in DIN 277 are the following:
NetArea Type_DIN | Use |
---|---|
Utilized | Living, office, production, craft, experiments, storage, sale, education, culture, health care, other uses |
Technical | Operations, mechanical room, water supply, heating room, electrical room, etc. |
Circulation | Halls, corridors, stairs, elevators, etc. |
You can use AutoCAD objects like closed polylines or rectangles to generate a space that is deducted from an associative space. You could do this for example to represent construction spaces or otherwise unavailable areas. Since AutoCAD objects cannot be classified to control their behavior, the following standard behavior is applied to enclosed deducted spaces formed by AutoCAD objects in the DIN 277 standard:
The net boundaries are created on the inside of the walls.
Technical spaces: When the area of a technical space is larger than or equal to 1 m 2 , the net boundary will be calculated to the inside of the wall. When the area of a technical space is smaller than 1 m 2 , the space will not have a net boundary, and the area will be calculated as constructive area.
The gross boundaries are created according to the following rules:
Gross Area (Space Type_DIN A) | |
---|---|
Adjacent Space | Boundary |
Space Type_DIN A | Measured from centerline of wall |
Space Type_DIN B or C, or no adjacent space | Measured from outside face of wall |
Adjacent space not classified (unspecified) | Measured from outside face of wall |
Gross Area (Space Type_DIN B) | |
---|---|
Adjacent Spaces | Boundary |
Space Type_DIN A | Measured from inside face of wall |
Space Type_DIN B | Measured from centerline of wall |
Space Type_DIN C or no adjacent space | Measured from outside face of wall |
Adjacent space not classified (unspecified) | Measured from outside face of wall |
Gross Area (SpaceType_DIN C) | |
---|---|
Adjacent Spaces | Boundary |
Space Type_DIN A or B | Measured from inside face of wall |
Space Type_DIN C | Measured from centerline of wall |
No adjacent space | Measure from outside face of wall |
Adjacent space not classified (unspecified) | Measured from outside face of wall |
