This glossary defines terms used in the International Property Measurement Standards and is only applicable to these Standards.

Balustrade

A protective barrier such as a Wall, parapet, railings, or other construction feature that enables Floor Areawith one or more open sides to be used safely.

Boundary

A physical or non-physical line denoting the perimeter of an area to be measured.

Building

A construction providing shelter from the environment for occupants or contents, partially or totally enclosed by a roof, designed to stand in one place and comprising all levels within the construction.

Clear Height

The height within a level of a Building or part of a Building measured from the floor surface to the lowest point of the structural element above, ignoring the existence of any brackets, struts or fixtures and fittings. Refer to Diagram 27

Column

A Building member may also be known as a Pillar, generally cylindrical or rectangular in shape, whose primary purpose is to provide structural support and having a maximum ratio of 4:1 comparing the longest and shortest horizontal dimensions.

Component

One of the main elements into which the Floor Area of a Building can be allocated.

Component Area

The Floor Area attributed to one of the Components.

Covered Area

The extent of the area of a Building covered by one or more roofs and the perimeter of which is sometimes referred to as the drip line, being the outermost permanent structural extension, exclusive of ornamental overhangs.

Demising Wall

A Wall, other than an External Wall, between adjoining occupiers' space or an occupier's space and Standard Facilities.

External Floor Area

An external horizontal structure at any floor level of a Building with a Balustrade to the open sides and including in this definition generally accessible balconies, colonnades (with balustrade), rooftop terraces, external galleries and loggias but excluding structures such as patios and Level 0 terraces when not integral to the structural construction of the Building.

External Wall

The enclosing element of aBuilding, excluding appendages and ornamental features, that separates the interior area from the exterior.

Finished Surface

The Wall surface directly above the horizontal wall-floor junction, ignoring any part-height walls, fittings, skirting boards, cable-trunking, pipework and heating or cooling units.

Floor Area

The area of a normally horizontal, permanent, load-bearing structure, inclusive of areas occupied by Walls, Columns, stairs, staircase openings, lift shafts and other vertical penetrations, for all or part of each level of a Building.

Internal Dominant Face (IDF)

The inside surface area comprising more than 50 per cent of the lowest 2.75 metres measured vertically from the structural floor surface, or to the ceiling if lower, for each Wall Section. If such does not occur or, if the IDF is not vertical, the Finished Surface is deemed to be the IDF.

Internal Height

The height within a Building or part of a Building measured from the floor to the lowest point of a ceiling, suspended ceiling or similar defining feature. Refer to Diagram 28

Internal Wall

A full-height Wall within a Building that separates one interior area from another.

IPMS

International Property Measurement Standards.

IPMSC

The International Property Measurement Standards Coalition.

IPMS 1

Floor Area measured to the external extent of the External Walls and to any External Floor Areas, Sheltered Areas and Notional Boundaries. Refer to Diagram 29 and Diagram 30

IPMS 2

Floor Area measured to the internal extent of the IDF and any Notional Boundaries andExternal Floor Areas. Refer to Diagram 31 and Diagram 32

IPMS 3A

The Floor Area available on an exclusive basis to an occupier measured externally and including any External Floor Areas, Sheltered Areas and Secondary Areas. Refer to Diagram 33 and Diagram 35

IPMS 3B

The Floor Area available on an exclusive basis to an occupier measured internally to the IDF and any Demising Walls and Notional Boundaries. Refer to Diagram 34 and Diagram 36

IPMS 4A

The selectedFloor Areaina Building measured to Finished Surfaces andany Notional Boundaries including all Floor Area occupied by Walls and Columns. Refer to Diagram 37

IPMS 4B

The selectedFloor Areaina Building measured to Finished Surfaces and any Notional Boundaries excluding (subtracting) all Floor Area occupied by Walls and Columns. Refer to Diagram 38

Limited Use Areas

Areas in Buildings that are incapable of legal or effective occupation due to local or national legislation or practical circumstances.

Mezzanine

An intermediate or partial floor that is usually fully or partially open on one or more sides.

Notional Boundary

A non-physical line, that forms part or all of a Boundary.

Pillar

See Column.

Property

Any real estate asset in the built environment.

Property Industry

Users, Service Providers and Third Parties.

Secondary Area

A demised area forming part of the Building that supports the primary use of any exclusive use area.

Service Provider

Any entity providing real estate related services to a User or Third Party including, but not limited to, valuers, surveyors, facility managers, property managers, asset managers, agents and brokers, space measurement professionals, cost consultants, interior designers and architects.

Sheltered Area

Any part of the Covered Area that is not fully enclosed where the permanent structural extension above provides effective shelter.

StandardsSetting Committee (SSC)

The committee appointed by the IPMSC to develop global standards for the measurement of Buildings.

Standard Facilities

Shared areas in a Building that typically do not change over time, such as circulation areas, stairs, escalators, lifts/elevators and their motor rooms, toilets, cleaners' cupboards, plant rooms, fire refuge areas and maintenance rooms.

Temporary Structure

A physical element within or attached to a Building installed on an interim basis, the removal of which would not damage the physical integrity of the Building.

Third Party

Any entity other than a User or Service Provider with an interest in property measurement including, but not limited to, governments, banks, other property financing bodies, data analysts and researchers.

User

Any entity other than a Service Provider or Third Party with an interest in property measurement including, but not limitedto owner-occupiers, developers, investors, purchasers, vendors, landlords and tenants.

Wall

A normally vertical element, whether or not load-bearing, that separates one area from another.

Wall Section

The lateral extent of each section of an External Wall or other external construction feature where the inside finished surface area of each part of a window, Wall or other external construction feature varies from the inside surface area of the adjoining window, Wall or external construction feature, ignoring the existence of any Columns.
