What is Net Internal Area (NIA)?
Net Internal Area (NIA) is a measurement utilized in commercial property to determine the "functional space" within a structure. Usable area means the available locations for tenants' unique or sole use, such as offices, retail space, labs, and production. Areas excluded from an NIA calculation include common locations such as shared lobbies, toilets, or elevators.
NIA is an important metric for proprietors and tenants, as it provides a standardized way to assess the actual location offered for profession and use within a structure.
Note that meanings of NIA - consisting of which areas count towards it and which do not - vary worldwide. Hence, it's best to contact local authorities or a professional appraiser for your place's most used measurement requirements. Many nations are moving towards International Residential or commercial property Measurement Standards (IPMS), established by more than 80 professionals and non-profit companies, to document international residential or commercial property measurement requirements.
Practical Tips on How to Measure and Calculate Net Internal Area
NIA is essentially the total internal area of a structure minus the interior walls and typical areas. In other words:
NIA = Gross Internal Area − (Interior Walls + Common Areas)
Here are a number of ways to calculate NIA:
Option 1: Use an existing plan or flooring strategy
If you have an existing blueprint or floor plan for the building, you can import it into layout software application like RoomSketcher. With RoomSketcher's integrated area calculator, you can get your NIA lead to seconds - just click to omit the common locations on the layout and after that choose the "Internal Zone Area" computation (which instantly omits the internal walls for you).
See Calculate the Total Area of a Layout to learn more on RoomSketcher's location calculations.
Option 2: Measure onsite
You can likewise measure up the residential or commercial property if you do not have access to an existing floor plan. If you understand the building's GIA, you can measure the internal walls and typical spaces and deduct them. Or, if you do not know the structure's GIA, you can accumulate all the usable space to determine the NIA. For instance:
Start with a walkaround - Walk around the residential or commercial property to get an idea of the shape and variety of floorings.
Sketch the external walls on paper or tablet - Make a sketch of the residential or commercial property shape or produce a digital sketch using layout software on your tablet.
Note the Usable Space vs the Common Space - Locate the areas or rooms that are usable space and mark these on your sketch. Also, keep in mind the typical areas intended to be shared amongst occupants so you do not include them in the estimation.
Get the measurements - Now, utilize a tape step, roto wheel, or a laser to determine the size of any space or area that counts as usable space. It's helpful to divide the locations into rectangles and measure from the inside of all walls. Once you have actually measured up one side of a rectangle, proceed and determine the other instructions. Remember, don't consist of any typical areas or shared areas amongst renters.
Do the mathematics - Multiply the length and width of each rectangle to calculate its size. Add together all the rectangular functional locations on the floor. Repeat for all floors, and amount the outcome to compute the building's Net Internal Area (NIA).
What Does Net Internal Area Include?
NIA describes how much "functional space" a building's interior includes. Examples of locations to include in an NIA measurement are:
Exclusive use space, such as all rooms or locations planned to be utilized by a single business or renter, such as reception areas, workplaces, training rooms, laboratories, workshops, retail space, producing space, storage rooms, personnel or break spaces, etc.
Exclusive use atriums and entryway halls utilized by one business or renter.
Built-in cabinets and storage within special use locations.
Removable partitions. Include the thickness of non-permanent partitions.
Ramps and other sloping or stepped components if they are within the unique use area.
Ventilation or heating system areas inside an exclusive usage location.
"Because standards differ somewhat around the world, contact your regional authorities for a total list of the basic additions in your area. For example, expect you utilize the International Residential or commercial property Measurement Standards (IPMS). Because case, your estimation would include columns and renter parts of shared walls (likewise called party walls.)"
Net Internal Area Exclusions
NIA computations omit typical areas (also called balance locations) due to the fact that they are ruled out specific to a particular resident. Examples include:
- Shared entryway halls, lobbies, atriums, and landing areas.
- Shared washrooms, toilets, restrooms, and janitorial rooms that save products and devices used to maintain typical locations in a structure.
- Lifts or elevators that more than one occupant usages.
- Internal structural walls that separate renters.
- Any locations controlled by external authorities such as utility business.
- Spaces that are taken up with heating and cooling equipment, and so on, if the equipment makes the rest of the space unusable.
- Any room or area with a ceiling height lower than 1.5 m (5ft).

NIA Compared: How It Differs from Other Measurement Standards
Let's take an appearance at the distinctions in between Net Internal Area (NIA) and other estimations. For additional info on measurement standards, see GIA Explained, and What is Gross Living Area?
Net Internal Area (NIA) vs. Gross Floor Area (GFA)
The Gross Floor Area (GFA) is usually defined as the overall area of the building. GFA includes external walls and all areas inside the structure, consisting of entryway lobbies and other common locations, lifts/elevators, stairwells, mechanical equipment areas, passages, etc. On the other hand, NIA does not include external or internal walls or common locations.
Net Internal Area (NIA) vs. Gross Internal Area (GIA)
GIA (likewise understood as Gross Internal Floor Area) consists of everything determined from inside the external walls, including internal walls and typical areas in a . In contrast, NIA does not include the internal walls and typical locations.
Net Internal Area (NIA) vs. Gross Living Area (GLA)
Gross Living Area (GLA) is used for residential instead of business residential or commercial properties. As such, the measurements are unrelated. To get more information about GLA, see What is Gross Living Area, and How do you Calculate it?
Net Internal Area (NIA) vs. Gross Building Area (GBA)
Net Internal Area describes the amount of usable space within a building and does not include external walls, internal walls, or typical spaces. On the other hand, Gross Building Area explains the total location of a building and consists of typical locations in addition to internal and external walls.
GBA is comparable to Gross Floor Area (GFA) in the business world.
The Importance of Accurate NIA Calculation
The Net Internal Area is crucial for different functions:
Rentable Area: In industrial leases, rent is frequently based on the NIA, and renters are charged based on the usable space they will inhabit or utilize, plus a portion of the common areas. Space Planning: For renters and architects, NIA helps in area planning and designing the layout of offices, conference room, and other functional spaces. Comparisons: NIA offers a standardized metric for comparing different residential or commercial properties. When evaluating potential spaces, occupants and proprietors can use NIA to compare the expense and performance of space. Lease Negotiations: NIA is a crucial consider lease settlements. Understanding the NIA enables renters and property owners to negotiate lease terms, consisting of rent, upkeep expenses, and other charges based upon the functional space. Building Efficiency: Landlords and residential or commercial property managers utilize NIA to evaluate the performance of a structure's layout and to make enhancements that take full advantage of the functional area.
Thus, NIA should be measured properly and using the agreed-upon requirements in your area.
Frequently Asked Questions About NIA
Does the Net Internal Area (NIA) include stairs?
Stairs and ramps are included in the NIA if they are within the exclusive functional area of a single company/tenant. Shared stairs and ramps (utilized by numerous lessees) are left out from the NIA measurement.
What is the difference between Net Internal Area (NIA) vs. Gross Leasable/Rentable Area
Some leases use the Gross Lease Area as a basis for rent computations. A customer's Gross Leasable Area typically includes:
- Their functional location or NIA.
- The area occupied by any external walls nearby to their location. For example, a glass shopfront or a plain wall.
- The space inhabited by their 1/2 of any shared internal walls or celebration walls.
- A pro-rata share of the typical location. For instance, if a renter will inhabit 1/3 of the usable space, their Gross Leasable Area estimation would consist of 1/3 of the typical location space.
If a building is occupied by a single occupant, then the GLA is the exact same as the GFA.
What is the distinction between Net Internal Area (NIA) vs. Net Leasable/Lettable Area?
Some leases utilize the Net Leaseable Area (NLA) as a basis for rent calculations. A customer's Net Leasable Area or Net Leasable Area is typically defined as their usable location (or part of the NIA) inside a structure. Tenants may then pay an extra pro-rata cost for upkeep and making use of the common area.
Making NIA Measurements Easy and Accurate
In summary, Net Internal Area is an important metric in business property that assists figure out the actual usable space within a building. It plays a function in lease arrangements, area planning, and general performance assessments for both proprietors and renters. It is among a number of basic measurements used in business realty.
To accurately calculate NIA, you can measure up the functional space in a building or utilize Floor Plan Software, like RoomSketcher, to improve the process of determining NIA.
