Concept: Remaining Area and Usable Area Calculations

There’s a key difference between how the Space Inventory application calculates Usable Area, and how the Space Planning system brings over Usable Area and represents that area in allocations .

Application	Usable Area
Space Inventory	Floor Usable Area = Internal Gross Area - sum of room area for rooms that have super-categories of VERT and SERV
Space Planning	The system gives an allocation (a group) an Allocation Type of “Usable Area – Owned” group area_manual = sum of room area for rooms that have a super-category of USBL

For many floors, these values will be the same. However, there will be discrepancies if:

• any rooms on a floor contain a super-category of OTHR
• the floor is not drawn such that rooms take up all space in the internal gross area; that is to say, there is a non-zero “Remaining Area” in the Floors table ( fl.area_remain )

There is difference between Space Inventory and Space Planning for Remaining Area:

Application	Remaining Area
Space Inventory	Floor Remaining Area = Internal Gross Area - sum of room areas (this accounts for all area that is not drawn as rooms)
Space Planning	Unavailable Remaining Area = Internal Gross Area - sum of groups of allocation types “Usable Area – Owned”, “Usable Area – Leased”, “Unavailable – Vertical Penetration”, and “Unavailable – Service Area”

Again, the discrepancy between the two may be accounted for by any rooms that have a super-category of OTHR, or any rooms that are not categorized. The goal is to have the floor’s stack area add up to its Internal Gross Area, which it does.
