GBA (Gross Building Area): GBA is a building's total floor area, calculated as a geometry's area times its Levels, and it counts every building and basement geometry.

GFA (Gross Floor Area): GFA is Giraffe's net area, calculated as GBA times the usage's Efficiency.

NSA (Net Saleable Area): NSA is the floor area you can sell or rent, calculated as GBA times the usage's Sell efficiency.

NRA (Net Rentable Area): NRA is the name imperial projects use for saleable area, calculated as GBA times the usage's Sell efficiency.

FAR (Floor Area Ratio): FAR is total building area divided by site area, and Urban uses GFA unless you select GBA or NSA.

FSR (Floor Space Ratio): FSR is the name metric projects use for FAR, the total building area divided by the site area.

Site area: The site area is the area inside the project boundary, unless you type your own value on the Setup tab of Project Settings.

Building footprint: The building footprint is the ground area under your buildings, including overhangs.

Site coverage: Site coverage is how your site area splits into building footprint, hardscape, and open space, shown as a chart in Urban.

Hardscape: Hardscape is the part of the site covered by roads, footpaths, on-grade parking, and plazas.

Open space: Open space is the site area left after you take out the building footprint and hardscape, so landscape counts as open space.

Paved area: Paved area is the total area of roads, footpaths, on-grade parking lots, and plazas.

Facade area: Facade area is a building's outside wall area, calculated as perimeter times Floor to Floor times Levels, minus walls shared with touching geometries.

Party wall area: Party wall area is the wall area where two building geometries touch.

Roof area: Roof area is the exposed top face of a geometry, after Giraffe takes out any area covered by geometries stacked on top.

Floor facade: Floor facade is the ratio of above-ground GBA to facade area in Urban, which leaves out basements.

Parking provided: Parking provided is the number of parking bays your design supplies.

Parking required: Parking required is the number of parking bays your design needs, based on each usage's parking rates.

Dwelling count: The dwelling count is the number of homes in your design, worked out from each usage's Unit Mix or from a Dwelling Count you type in.

Analytics: Analytics is the app where you build your own reports from your geometries, their usages, and their properties, like a spreadsheet that's tied to your model.

Urban: Urban is a fixed report of standard real estate metrics, such as GBA, FAR, site coverage, parking, and dwelling counts, that updates as you draw.

Formula: A formula combines a measure's components with math and functions, such as A * B.

Roll-up operation: A roll-up operation sets how a measure combines its results from many geometries into one number: Sum, Average, Minimum, Maximum, Count, or Constant.

Filter: A filter limits a measure to the geometries that match the rules you set.

Subtotal: A subtotal adds up the measures in a category that share a unit.

Group by: Group by splits a report's results into columns by a property, such as Usage, Building, or Layer.

Unit: A measure's unit sets what its result is measured in, such as Square Feet, Currency, or Percent, and you can make your own.

Precision: Precision sets how many decimal places a measure rounds to.

Usage: A usage is a saved set of assumptions, such as Floor to Floor, Efficiency, parking rates, and Unit Mix, that you apply to geometries so they all update together.

Usage Editor: The Usage Editor is the app where you create and edit usages.

Usage Table: The Usage Table shows all of your usages in one table, so you can edit them in bulk.

Usage type: A usage type tells Giraffe what a usage represents, such as a building or a road, so its geometries count toward the right metrics.

Building: A Building usage represents building massing and counts toward GBA, GFA, FAR, and site coverage.

Dwelling: A Dwelling usage represents individual homes or units, each counted as a dwelling.

Basement: A Basement usage represents building area below grade, which counts toward GBA and not toward site coverage.

Land Use: A Land Use usage models zoning and allowable built form across many lots, and Urban doesn't count it.

Landscape: A Landscape usage represents green space or water, on the ground or on a roof.

Road/Path: A Road/Path usage represents roads and footpaths, drawn as lines.

Paved Area: A Paved Area usage represents plazas, on-grade parking, and other hard surfaces.

Property type: A property type sets what a property holds: text, a number, a toggle, or a choice from a list.

Override: An override is a property value you set on one geometry, which takes priority over the value from its usage.

Efficiency: Efficiency is the percentage of GBA that counts as GFA, set on each usage.

Sell efficiency: Sell efficiency is the percentage of GBA that counts as saleable area, NSA or NRA, set on each usage.

Unit Mix: The Unit Mix is each unit type's share of the homes in a usage's Dwellings group, and Giraffe uses it with Unit Size to count dwellings.

Unit Size: Unit Size is the floor area of each unit type in a usage's Dwellings group.

Dwelling Count: The Dwelling Count property sets the number of homes in a geometry by hand, in place of the count from the Unit Mix.

Parking rates: A usage's Parking Required and Parking Provided rates set parking bays per 100 m² or 1,000 ft², and usages with dwellings can set Parking Required per dwelling.

Geometry: A geometry is any shape you draw in Giraffe, such as a point, a line, a polygon, or a 3D mass.

Drawing toolbar: The drawing toolbar holds the tools you use to draw and edit geometries.

Control points and midpoints: Control points are a geometry's corners, and midpoints sit halfway along each edge, so you can drag either one to reshape it.

Snapping and Ortho: Snapping pulls your cursor onto nearby points and edges as you draw, and Ortho locks lines to right angles.

Levels: Levels are the floors of a building, also called storeys or stories.

Floor to Floor: Floor to Floor is the height of one level, so a building's height is its Levels times its Floor to Floor.

Height: The Height property sets a geometry's total height directly, and a geometry with a Height set doesn't count toward building areas like GBA.

Stack order: Stack order sets how building geometries on the same drawing layer sit on top of each other, like a tower on a podium.

Base height: Base height lifts a geometry off the ground by a set distance, for things like sky bridges.
