The primary factors in the calculation are: the type of occupancy, along with the available floor space and the available means of egress.
When creating or modifying a building, the building use and occupancy load determine the fire resistance requirements. Or the desired type and occupancy load may help determine the necessary area and means of egress.
Buildings are classified by the ICC (International Code Council) by group and division.
Groups - defined
Group A - Assembly
Group B - Business
Group E - Educational
Group F - Factory and Industrial
Group H - Hazardous
Group I - Industrial
Group M - Mercantile
Group R - Residential
Group S - Storage
Group u - Utility
Each group mostly has more than one division, categorized by number; I.E.
Group A Division 1 , which is the most stringent category for fire resistant materials and means of egress code rules, is more stringent than Group A
Division 4.
Like wise , Group U Division 2, which is the lowest requirements is less stringent
than Group U Division 1 requirements.
In summary, the lower the letter and number, the more stringent are the fire
resistive , and means of egress components.
To know the fire resistive construction and means of egress requirements of your building, consult the building code book for your state ; which may supersede
the I.C.C.
To be absolutely sure ,consult with your local building department with information about what kind of use the building is intended for , how big of an occupancy intended , and whether or not it is connected or near to another business of same or different classification.
If this pool is indoors consult your local fire marshal for the restrictions on the building occupancy level
There are actually a few ways that you can calculate occupancy rate. You can have general unit occupancy, occupancy by square footage or economic occupancy. There is an article in the Storage Facilitator that breaks down each of these and tells you what percentage you should aim for. Check it out in the related links section.
It would depend almost entirely on what that room is USED for, i.e., the type of occupancy. If it is a storage room in a retail store, you are not allowed to have more than one person for each 300 sq ft (i.e., 5 people), but if it is a classroom in a K-12 education occupancy, you would be allowed one for each 20 sq ft of open space (net floorspace), i.e., 72 people. The NFPA Life Safety Code, or other similar code adopted in your jurisdiction, will determine what load factors to use for your particular occupancy, whatever it is. After you know the permissible load by area, you then calculate the permissible exit load, based upon the location, type and width of the various doors. If the exit load is smaller than the area load, your occupancy is limited by the exits.
The fire department is who determines the occupancy limits in public buildings. It is important to not go over the occupancy limit they have determined.
If you mean the maximum occupancy of a room, then several things are considered. The square footage of the room, the room's purpose, and the number of emergency exits that exist are factored in.
Net floorspace divided by load factor from occupancy tables of applicable code. For instance, NFPA 101 requires 7 sq ft per person in compact dance areas and 15 sq ft per person where there is seating, provided it is not fixed seating. You then calculate the egress load by allowing one person for each 0.2 inches of doorway or hallway (whichever is narrower), or 0.3 inches if there are stairs. The lower number (area load or egress load) is the overall limit for that occupancy. There are, however, many other factors for each specific location, such as whether the main doors can accommodate at least 2/3 of the max load, whether there are sprinklers, whether there is live entertainment, what floor of the building it's on, what kind of building structure it is, etc.

usually by the number of seats
Divide current occupancy by the total possible occupancy and multiply by 100. For example: If a facility has a total possible occupancy of 100 and the current occupancy is 75 then the occupancy rate is 75%. 75 / 100 * 100 = 75 % If you do not multiply by 100 then you have the answer as a decimal fraction.
