Overview

EN ISO 4157-2:1998 - "Construction drawings - Designation systems - Part 2: Room names and numbers" specifies rules for assigning room names and room numbers in buildings. The standard sets out clear principles for identifying rooms, areas, spaces and voids on construction drawings and in everyday building use. It is intended for day-to-day identification (not full project life-cycle identification, which is covered by ISO 4157-3).

Key topics and requirements

• Scope: Applies to room designation systems used for identification of rooms in everyday building operation.
• Logical numbering: Assign room numbers in a logical, preferably consecutive order on each floor, starting with number n01 (n = floor number).
• Floor-prefix format: Prefer two-digit room numbers preceded by the floor number (e.g., 101–199, 201–299). Alternative digit schemes (two-, four-, or five-digit) are allowed only for very small or very large buildings but must be consistent across the building.
• "Room 0" rule: Numbers ending in zero (e.g., 300, 4000) are reserved to denote the exterior of that floor - rooms must not be numbered zero.
• Alphanumeric codes: Ground, mezzanine, basement or under-grade levels may use letter prefixes (G01, M02, B03, U04). Four-digit numbers should not be interspaced or punctuated.
• Placement on drawings and in building: Room number and assigned room name must be shown inside each room on drawings and posted at doors or openings in the building (underlined on drawings only). Small rooms may show number only on drawings and include names in a table.
• Numbering sequence guidance: Numbering should facilitate orientation (for example, clockwise from main entrance), or use conventional zig-zag numbering in corridors (hotels). Vertical shafts (stairs, elevators) are recommended to carry consistent numbers across floors (e.g., 112, 212, 312).
• Changes and additions: Added rooms get the next available unused number; merged rooms retain the lowest number; combined rooms use the lowest available numbers unless existing signage is retained.
• Basements/attics: Number per ISO 4157-1 floor designation rules.

Applications and users

EN ISO 4157-2 is practical for:

• Architects and designers creating construction drawings and room schedules
• Facility managers, building owners and operators (FM/CADM) implementing signage and asset location
• BIM coordinators and CAD drafters enforcing consistent room identification in models and drawings
• Contractors and asset-management software vendors integrating room IDs into maintenance and operational systems

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
International Standard ISO 4157-2 was prepared by Technical Committee ISO/TC 10, Technical drawings, product
definition and related documentation, Subcommittee SC 8, Construction documentation.
This second edition cancels and replaces the first edition (ISO 4157-2:1982), which has been technically revised.
ISO 4157 consists of the following parts, under the general title Construction drawings — Designation systems:
 Part 1: Buildings and parts of buildings
 Part 2: Room names and numbers
 Part 3: Room identifiers

Part 2:
Room names and numbers
1 Scope
This part of ISO 4157 specifies requirements for designation systems for rooms, areas, spaces, and voids in
buildings by room names and numbers. It is intended for identification of rooms in the daily use of the buildings.
For identification of rooms in a project throughout its life-cycle, i.e. conception, programming, planning, erection,
maintenance, remodelling and demolition phases, see ISO 4157-3.
2 Normative reference
The following standard contains provisions, which through reference in this text, constitute provisions of this part of
ISO 4157. At the time of publication, the edition indicated was valid. All standards are subject to revision, and
parties to agreements based on this part of ISO 4157 are encouraged to investigate the possibility of applying the
most recent edition of the standard indicated below. Members of IEC and ISO maintain registers of currently valid
International Standards.

3 Definitions
For the purposes of this part of ISO 4157, the definitions given in ISO 4157-1 apply.
4 Room number principle
4.1 Logical order
Room numbers shall be assigned to all rooms on each floor in a logical order, preferably consecutive, starting with
number n01 (where n indicates floor number) within the limits of all the parts of the building. Such limits need not be
physical walls, so that outdoor or covered areas which are appropriate to include in the numbering system may be
assigned room numbers, e.g. an enclosed garden, a pool area, a carport, a covered loggia and in-between spaces.
4.2 Separate buildings
If several buildings are included in one building project, room numbers shall be allocated independently to each
building in accordance with 4.1. Separate buildings may be adjacent to each other, and may be interconnected by
doors or openings.
