Transmittal Notice

  1. Explanation of Material Transmitted:  This chapter establishes the National Institutes of Health’s (NIH) policy and guidelines for identifying, reviewing, and approving room numbering systems in NIH owned and leased facilities.
  2. Filing Instructions:

          Insert:  NIH Policy Manual, Chapter 1212, dated 08/11/2022

PLEASE NOTE:  For information on:

This chapter establishes the policy, procedures, and guidelines for establishing room numbers in NIH owned and leased facilities.

This chapter is applicable to all NIH owned (i.e., new, and existing), operated, and leased facilities.  It does not apply to hospital space in the NIH Clinical Center Complex (CCC) on the NIH Bethesda campus, or buildings that constitute the Research Triangle Park, North Carolina, Rocky Mountain Laboratories, Hamilton, Montana, and the Frederick National Cancer Research Center, Frederick, Maryland campuses.

The Office of Research Facilities Development and Operations (ORFDO) is responsible for providing, managing, and maintaining NIH real property assets.  This includes establishing room numbering guidelines to enhance wayfinding within NIH buildings, addressing functional relationships between organizations, ensuring spaces are used for the intended purpose, and for effective building operations and maintenance activities.

NIH occupies over two-hundred (200) owned buildings in six (6) locations and eighty (80) leased buildings nation-wide in three (3) locations. Approximately 50,000 rooms exist in NIH owned buildings and 27,000 in the leased facilities inventory.

This vast portfolio of rooms requires a comprehensive, uniform, yet flexible numbering system to satisfy operations in NIH’s facilities.

It is the policy of NIH for ICO’s to comply with ORFDO’s  requirements for establishing, reviewing, and approving room numbers using the management and internal controls established herein.

The room numbering requirements as outlined in Appendix 1, apply to all newly constructed facilities, as well as partial renovations of existing facilities. Partial renovations require that any new room numbers integrate as seamlessly as possible with the existing room numbering scheme and sequencing in adjacent areas, in order to maintain optimal wayfinding.  Every effort should be made to assign room numbers that maintain the overall flow and sequencing of numbers with the entire floor, without the need to change room numbers outside of the limits-of-work area of a renovation. 

ORFDO reserves the right to approve all new room numbers. Any deviations to this policy must be requested in writing for ORFDOs approval.

Appendix 1 – Room Numbering Standards

Room Numbering Strategy

Floor plans vary greatly in size and complexity, and this impacts the ideal numbering schema, but in order to provide for maximum flexibility throughout the lifecycle of a building, the following concepts should be considered:

Mandatory room number formatting rules:

  • Each room number must be unique for a given building. No duplicate room numbers within the same building or facility are allowed.
  • Do not use the letters “I” or “O” in any room number, as this can be easily confused for the digits “1” or “0”.

Room Numbering diagram. Example room number format displayed starting with the first identifier being the floor number, second letter referencing Building Area / Wing, third identifier referencing Building Grid / Zone, forth being Suite / Room Number, and final identifier being Inner Room / Space.

General format of numbers:

  • Assignable spaces:
    • Floor Designator: 1-2  characters (mandatory).
      • For non-interstitial floors 01 and above, use floor level, (without leading zero)
      • For purely mechanical interstitial floors, use the interstitial level indicator, which is the floor level immediately below the interstitial floor, with an “I” character (e.g., “1I”, “2I”, “GI”, “BI”, etc.)
      • For floors designated as “Ground Floor” use “G”. For levels designated as “Basement Level X”, use the corresponding basement level indicator. (e. g. “B1”, “B2”, etc.)
  • Building Area/ Wing: (single alpha character): depends on size of floor plate. If relatively small, use “A” or omit. Also used for major additions, using the next sequential alpha character not in current use.
  • Building Grid: an ordering device, based on column grid, or approx.10’ (represents practical min. dimension of an average-sized office. This grid represents the first digit in the room number, i.e., 10, 20, 30, etc.
  • Suite / Room Number:
    • Generally, 2 digits, (sometimes 3 if the number of rooms warrants), including the “building grid” designator (see above). Generally, these should follow a natural sequencing that reflects the order of rooms as an occupant moves through the building. Suite / room numbers, shall sequence in a clockwise direction (sequencing of numbers through the wing or building grid/zone)
    • Odd / even numbers on opposite sides of corridor (or building) Preference is for rooms on the North or West side of a major corridor to be odd, E and S = even.
    • “Skip” numbers to account for and provide flexibility for future renovations, and further dividing of space.   
  • Circulation spaces:
    • Non-assignable Circulation spaces shall have text string prefixes:
      Examples:
      • Corridor = CORR
      • Elevator = ELEV
      and shall be assigned a General format number following the standard TEXT Prefix:
      Examples:
      • CORR3B22, (if on Floor 3, wing B, “grid 22”
      • LOBBY1A10, if on Floor 1, wing A, “grid 10”
    • Assignable circulation spaces, such as controlled access corridors, are assigned a number with the same formatting as other assignable rooms (no text string prefix). Additionally, circulation areas in open office rooms are considered part of the main room and is not assigned a separate number.
  • Mandatory vertical consistency – Stairs / Elevators / Shafts
    Examples:
    • STAIR1A01, STAIR2A01, STAIR3A01, etc.
    • ELEV1C20, ELEV2C20, ELEV3C20, etc.
  • “Interior-accessed” rooms that comprise a “suite”:  (Rooms with full-height walls and lockable doors), that are considered as part of a “suite” shall be assigned the main room or suite number, and given a unique, sequential (clockwise) alpha character suffix:
    • Example: 3B41A, 3B41B, etc. if in suite 3B41
  • Cubicles and workstations within suites (with partial-height walls, or phantom walls, such as cubicles, workstations, etc.) shall use a dash followed by 2 digits.
    • Example: 4C26-01, 4C26-02, etc. if in suite 4C26.
  • NIH standard practice is to number all cubicle and workstations individually. Please note that additionally, some lab bench spaces are segregated in this manner, but not all, and generally, lab benches are only assigned separate numbers (by PARB) on a case-by-case basis, at the request of the IC occupying the particular laboratory space.
