DRAFT TERMINOLOGY(as of 2001-01-15)

Terms related to Statements of Requirements

Functionality, Serviceability and Performanceof Buildings, Facilities and Constructed Assets

For dissemination to CIB Task #3 Project team

Listed below is a preliminary list of terms and draft proposals for definitions of some terms in the English language(the working language of ASTM, CIB, and one of the working languages of ISO). Terms below are included for oneor more of the following reasons: (a) the term is part of the emerging focus on Functionality, Serviceability andPerformance, (b) there are different meanings for the term; or (c) the term or concept is emerging, and not yetstable; or (d) the term is known to have different meanings in different countries.

All terms are not yet identified as verbs, adjectives or nouns, etc. All cross-references are not yet implemented.Some necessary terms are listed but not yet defined. Notes for further work, or comments, have been included inangle brackets<< >>.

Where definitions are adopted from other sources, they are copied exactly, and the source is identified at the rightmargin following the definition. In those instances where the equivalent term in French is known, it is listed inparenthesis after the English term.

Even within the English language, there are often different terms used to express the same concept, and the sameterm might be used to mean different concepts. In time, we expect that English terms used in different countries,such as America, Australia, India, and the UK, will be cross-referenced in this terminology.

The format for definitions is based on that used by ASTM. Terms are grouped according to main subjects, tohelp people unfamiliar with English to understand related terms. Because of this, the definitions of many terms arenot located in “dictionary sequence”. Where this occurs, cross references are placed in the location that would benormal for a dictionary. In the definitions of compound terms, the words are in the natural spoken order; however,cross-references are also provided for other “rotated” word sequences of common usage.

ASTM defines “terms”. This is practicable because ASTM only needs to consider the meaning of the term in asingle language, (American) English. This is different for the ISO documents, which define concepts, and then findthe equivalent term in various languages. For instance, in ISO, a concept may be defined in French or Chinesewhich does not have an English or German equivalent term, and therefore would not appear in a single languageterminology in English or German.

In time, this format will likely be converted to the ISO format, in light of the ultimate use of this document as a pre-standardization document ready to be submitted to ISO.

• health care facilities, n —<<Add>

• house, n (maison)—building intended in itsentirety as a dwelling. ASTM E 631

• judicial facilities, n —<<Add>

• office, n (bureau)—place, such as a room, suite, orbuilding, in which business, clerical, orprofessional activities are conducted.

ASTM E 631

SPACE AND FLOOR AREA<<Note: terms and definitions in this section arecurrently under review as part of the revision of theASTM standard on Floor Area Measurements>>

• building gross area, n (superficie brute d'unimmeuble)—sum of the floor areas of a buildingincluded within the outside face of outer buildingwalls for all stories.

DISCUSSION: Building gross area includesbasements, enclosed porches, penthouses,mechanical equipment, floors, lobbies,mezzanines, and corridors, provided they arewithin the outside face of the building. The areasof stairways, elevator shafts, mechanical serviceshafts, and ducts are to be included in buildinggross area for each floor through which they pass.Building gross area is measured from the outsideface of exterior walls on each floor, disregardingcornices, pilasters, buttresses, etc., that extendbeyond the wall face. The building gross area ofbasement space includes the area measured to theoutside face of basement or foundation walls. Forenclosed open courts, enclosed light wells,enclosed atria, or other interior spaces more thanone story in height, only the area on the lowest

floor is included, not the void above on upperlevels. Interstitial areas and unfinished attics areexcluded.

• building core and service area, n (noyau d'unimmeuble et aire de service)—floor area of afacility necessary for the general operation of abuilding that is not available for generaloccupancy, including: primary circulation areas,mechanical, electrical, telephone and custodialrooms serving individual floors; toilet rooms,building lobbies and atria, stairways, elevators,vertical shafts and chases, loading docks; and alsocentral, mechanical, electrical, telephone, andcustodial spaces and penthouses, but excludinginterstitial area.

DISCUSSION: Building core and service areais measured to the center of all interior wallsexcept in the following cases: where a stair,elevator, vertical shaft or chase adjoins amechanical room, electrical room, custodial room,toilet room, building lobby, or primary circulation;the area of the wall should be included in the areaof the stair, elevator, vertical shaft, or chase.

Where a building core or service area spaceadjoins a space designated as usable area, the areaof the wall should be included in the building coreor service area space.

An alternative method of classifying buildingcore and service areas may be used: measure tothe center of interior walls for all spaces. The useof this alternative method should be noted whenreporting area measurments.

Toilet rooms that are accessible to all of theoccupants on a floor of a building or that servethe general public should be classified as buildingcore and service areas. A toilet room that isaccessible only from a private office, or that is notavailable to all occupants on a floor would beclassified as a private toilet room and included inusable area for the tenant or occupant which itserves.

• building floor area, n, (superficie de plancher del’immmeuble)




• building loss factor, n (in a facility) (facteur deconstruction??)— that percentage of floor area ina building that is nominally available for use byoccupants, but is not effective for planning or useby occupants because of building elements ordesign features, such as inappropriate placementor alignment of columns and building grids,excessive circulation space, required oversizerooms because of floorplate configuration, and soon.

• building projection, n (saillie d'un immeuble)—pilaster, convector, baseboard heating unit,radiator, or other building element located in theinterior of a building wall that prevents the use ofthat space for furniture, equipment, circulation, orother functions. ASTM E 1480

• building service area (aire de service d'unimmeuble)—use preferred term building coreand service area

• circulation—See primary circulation; secondarycirculation

• facility floor area, n, (superficie de plancherutilisée par un groupe d’utilisateurs)

• floor area, n, (superficie de plancher)

• interstitial area, n, (vide)—area of load bearingsurfaces located above or below occupied buildingfloors that are not available for general occupancyand that contain building mechanical or electricalsystems predominantly serving adjacent floors orprovide access to such systems.

• primary circulation area n, (aire de circulationprincipale)—portion of a building that is a publiccorridor, lobby, or atrium; or is required for accessby all occupants on a floor to stairs, elevators,toilet rooms or building entrances.

• rentable floor area, n, (superficie de planchercalculée dans le contrat de location d’un grouped’utilisateurs) – See also rentable square foot.

• secondary circulation area, n, (aire de circulationsecondaire)—portion of a building required foraccess to some subdivision of space, whetherbounded by walls or not, that does not serve alloccupants on a floor, and that is not defined asprimary circulation area.

• support space, n, (in offices) —(locaux desoutien)—part of usable area not asigned ordedicated to a specific task or function. Supportspace includes meeting rooms, waiting areas,storage, lounges, operational equipment (e.g.computer rooms), copy areas, libraries and similarareas.

• usable area, n, —that part of the area on eachfloor inside the outside walls, that can be assignedor attributed to occupant groups. It includes thearea of interior walls, building columns andprojections, and secondary circulation, but not thearea of exterior walls, major vertical penetrations,primary circulation, building core and service area.

• workplace, n, (poste de travail)—part of a usablearea, intended for an individual or group to workin.

DISCUSSION: A workplace is identified byhaving been assigned to, or intended for, anindividual or a group or team. It may be anenclosed office; a part of an open plan office; or acombination of enclosed and open plan spaces.

• workstation, n, (poste de travail) (aménagementouvert)—all or part of a workplace, suitable forcarrying out one function or type of work.

DISCUSSION: Workstation(s) may beincluded in a workplace and in a workspace. Theboundaries of workstations may overlap, or theremay be gaps between workstations. For example,a workplace for an individual might include: (1) Aworkstation for computer work, equipped withpersonal computer, visual display unit, keyboard,and reference material; (2) A workstation fordesk-work and reference to documents; and (3) Aworkstation for telephoning. (The latter twoworkstations would likely overlap).




• open-plan workstation, n, (poste de travail enaménagement ouvert)—office workspace for oneperson, not enclosed by full-height walls. E 631

• workspace, n, (aire de travail)—part of usablearea, intended for a specific function or type ofwork.

DISCUSSION: A workspace is identified bythe function or type of work for which it isintended. It may include workplaces, and it mayinclude some area which is not intended forindividuals or groups, and therefore, is not aworkplace.
