A most helpful video. This works nicely for limited scope/scale Tenant Improvement (TI) projects but not Core & Shell (or Base Building, spec office projects) constructed with many future TI projects and permit applications in mind but for now there are no layouts to speak of. If you do a follow up one on such a spec office building's typical floor, better yet this very same building floor plate when it was permitted without any tenant, it would be very instructive and I would love to see how you might then go back and change, if anything, on AC 010. Great stuff, you clearly have a most excellent grasp on the codes.

Hi Archi Corner, Thank you so much for this very instructive videos! I have a questions on the Occupancy load round up. Would be possible to do the calculations room by room, and add the numbers without rounding up, then round up this final number. I understand the IBC doesn't specify, and it maybe depend of the specific project. I am thinking if you have many small rooms/offices and you round up in each one at the end your final occupancy load can be inflated. What are your thoughts on this? Thank you!

[@archicorner]

The code does not touch on this. After working with a jurisdiction for a while, you will see what each jurisdiction accepts. Therefore I think it may depend on your jurisdiction and what they accept, but for now, the code is silent on this issue.

[@googleit1131]

Question: I know what the differences in Gross and Net are, but does Gross occupancy factors affect how you calculate the areas? For example, if you have a row of private offices, would you calculate each office individually from the finished surface of the wall, each office individually from the center of the walls, or as one large "space"? I ask because I've seen all three ways of doing this, and I was hoping to get some additional input on this. It makes sense, to me, if you calculate them individually, but the definition of "Gross floor area" states that you have to include wall thicknesses, not just space where there's a finished floor.

[@archicorner]

1) Regardless of whether you are calculating occupant loads on an office by office method or if you are calculating them as a group, net will have to account for the walls. 2) You are correct, It is common to see both approaches, it is left up to you as the designer to pick which one you like best. There is no correct answer so as long as the information is provided in a clear manner for the plan reviewer to confirm that an office or area meets the egress requirements (i.e. number of exits).

[@lancecrane10]

Not sure I understand the calculation for the storage room. is it because the 100 ft is less than the 300 gross therefore only one person is the load and the Occ does change until the SF of the storage is greater than the 300 gross?

[@EricEngdahlAD]

Unfortunately the consideration of conference rooms versus general office space is more nuanced than this. Fortunately the issue of office egress design is very widely discussed, so instead of writing a new explanation I will copy from elsewhere: First, the IBC specifically addresses the common issue of small assembly spaces within other occupancies. The IBC states that the following rooms and spaces are NOT Assembly occupancies: - A room or space used for assembly purposes that has an occupant load of less than 50 people and is accessory to another occupancy type. - A room or space used for assembly purposes that is less than 750 square feet in area and is accessory to another occupancy type. Therefore, in terms of OCCUPANCY, the conference rooms and private offices are B. The video correctly shows the table with categories labeled "function of space." "You have to understand that "occupancy" (Chapter 3) and "function of space" (Table 1004.1.1) are two separate items. The conference room, although a B occupancy, is still an assembly function. So, the occupant load of a conference room is still based on the unconcentrated assembly number of Table 1004.1.1, which is 15sf per occupant. An assembly occupancy is required when the occupant load of a space is 50 or greater. The 750sf exception can be derived by multiplying the 15sf/occupant by 50. So, even if the occupant load may be greater than 50 in a 750sf conference room (concentrated or standing), you're not required to call the space an assembly occupancy. Now the confusion: Typically, the occupant load for the floor is based on the gross floor area of the B occupancy for that floor, including conference spaces, restrooms, closets, etc. This assumes that the users of those spaces are generally the employees of the office spaces. However, egress from the conference areas must be based on the actual occupant load of the conference areas. For example, assume four adjacent conference rooms (749sf each) share a small reception area. Egress width out of that reception area must be based on the total design occupant load of all those conference rooms, plus the reception area. Therefore, the reception area must have a minimum of two exits (Table 1015.1) with appropriate width." So to correct the video: the occupant calculation for the floor as a whole should treat the entire office floor as B occupancy, which will yield a result much smaller than the video says (adding them all up to 64 occupants is incorrect). However, when looking at the egress from a particular room, you do need to look at the occupant load of that room per the "function of space." For example, imagine a large office floor of B occupancy with an occupant load of 100sf/occupant. Imagine that all of the office workers from this large office floor were gathered in a conference room. If a fire broke out in that room, it would be important that the egress from that room be designed according to that "function of space," i.e. 15sf/occupant. However, when you then look at the egress of the floor as a whole, this can be calculated according to the total 100sf/occupant. The video's method would not yield an egress width in violation of code, only one much larger than required.

[@archicorner]

Eric;The videos provided by Archicorner are not meant to provide solutions to any project(s). The videos simply provide the viewer with general information so that the viewer can thereafter make more research and make his or her own design decisions. Architectural Design decisions should always be made by a licensed professional, as required by law. If you are a licensed architect, then ultimately you take on the risk by stamping and signing each and every plan with your name on it.It is of interest that your opinion included the note: "THE VIDEO'S METHOD WOULD NOT YIELD AN EGRESS WIDTH IN VIOLATION OF THE CODE [...]".Take care and thank you for leaving a note. Thank you. :)

[@iangeorge7472]

do you calculate occupant load for a Lobby???

[@tonyktso]

That may well be true per IBC and you made a very insightful distinction between occupancy type classification which has to do with how the "building" (or portion thereof) is regarded in the eyes of the code relative to risk thus all kinds of mandatory requirements and use function classification which drives occupant load FOR the space and the mandatory egress requirements tied to the load. It's a distinction hard to make clear in one's mind. However, NFPA 101 does not seem to share IBC's view towards calculating and compiling occupant load for the floor. Archicorner's video is more consistent with how NPFA 101 would insist that the designer compute the occupant load for the floor. With its 2018 edition, readily embraced by federal agencies upon release because they don't have to go through an adoption process with public input, where the introduction of new factors (150 for B-use, 15 for > 450 SF and 30 for < 450 for collaborative spaces) have now made perfectly safe and functioning office bldgs noncompliant as suddenly there are now more occupants on the floor than previously simply on account of moving away from Gross Floor Area divided by 100 Occp/GSF formula to yield total floor occupant load. I would be very interested to learn from you if you are aware of any authoritative documents that discuss this distinction between occupancy and function that you articulated so well and therefore how the codes, whether IBC or NFPA, intended floor occupant load to be computed for the sake of determining the exit and exit access capacities.

[@archicorner]

Fernando; Thank you for watching the video. This reply is not meant to provide you with any suggestions or recommendations of any kind. This reply is only to share my opinions. What you or any reader of this reply does with such information is at your own risk: Occupancy loads are typically based on the table you noted. What you local Authorities Having Jurisdiction (AHJs, such as Building Department and Fire Department) will accept will vary from one jurisdiction to the next. It may be possible that you could use 1:200 gross for residential space and apply it to the entire project and the AHJ's may accept it, but you will have to confirm that with your local AHJs. However you mentioned that the project has an "office". Does that mean that there is an office occupancy in the building? Does that also mean that you have multiple occupancies in the building? It may be possible that the areas within different occupancies may be classified differently such as the office which may require a load as "business areas" at 1:100 for example. Taking a quick trip to your local AHJ's office and confirm what they may accept before hand may save a lot of time in the end. Best of wishes to you in your project!

Hi Josue, I'd like to know how to categorize several ballrooms and prefunction area. Are they counted as a whole with certain/same load factor, or whether ballroom and prefunction area have their own load factor? Thank you

[@archicorner]

Don't get set back by the walls in a room or area. A large room or area can have different occupancy loads even if those areas are not separated by an actual wall or barrier. For example, a restaurant can have waiting area, and a dining area in the same room without walls dividing the areas. However, each area may have a different load factor based on chapter 10. I am guessing that your example is similar with the same large room providing different uses. As a designer, it is up to you to label each area clearly and provide the correct egress load.

[@MartyHuie]

nowhere in here did you address gross versus net. The offices should be calculated at gross square footage which requires you to take into account the thicknesses of all the walls. Your likely okay because you rounded up so well with all the spaces but still this is a big misconception. All the hallways/corridors need to be calculated also. And you should not only do your suite but should do the entire floor,, for you need to look at the exiting requirements for the floor not just your area

[@archicorner]

Marty Huie! This is an overdue response, sorry! Your feed back is much appreciated. Your comments regarding NET, vs, GROSS are valid. All areas within your suite should be accounted for. Whether you calculate the suite on a room by room basis or otherwise, it should be left up to the architect to decide. Both can be completed with a great deal of confidence, so as long as they are done thoughtfully. There is more than one way to skin a cat on this one. Calculating the common area corridors? That can be debated. Sounds like an odd request, but there have been plenty of odd request from AHJs in the past that one must adhere to. In most instanced, the AHJs do not ask for the whole floor to be calculated unless the load in your suite is such that the load for the floor may be put in question. This does not happen often so as long as you stay within the original occupancy the building was designed for. Nevertheless, the AHJ can make requests per their review and if they request it, then, you should be ready to provide, which it sounds like you are! A good architect will tell you when your occupancy load will trigger a whole-floor load analysis before it even gets to the AHJ. Marty; You have great videos on KZbin. They are very informative. Hopefully whoever reads this thread can go check out your channel too. Best of whishes -Archicorner.

[@TooLiveChris]

I have a one floor office renovation in California and the client wants to only make changes to three spaces. These are semi-enclosed rooms that they want to fully enclose. My question is do I have to calculate the entire floor (areas not in the contract)? or do I have to only take the square footage of the three spaces we are working on?

[@archicorner]

In cases were there are multiple tenants on the same floor, it is common for egress plans to show how the entire suite exits, not just the remodeled areas within the suite.

If I understand correctly, Assembly/Group A occupancies are partly defined by having at least 50 occupants. In situations such as a breakroom, where there would not be more than 50 people at a given time, does that cause a problem in terms of classifying those spaces as Assembly?

[@archicorner]

This is a common miss understanding. Chapter 3 talks about Occupancy Groups. Chapter 10 talks about Occupancy loads. Just because a room uses assembly occupancy loads for egress does not make that room an assembly occupancy group. A “conference room” is used for assembly regardless of the actual occupancy group classification.

[@rezahadian6647]

@@archicornerthank you for all your videos and efforts. In the same subject, when we calculate the occupancy load for office, and the whole office suite, has break room and conference room, why do we need to count the occupancy for break room and conference room separately? The same office people, sometimes use conference room or break room. The total number of occupants in office suite is still the same. Thanks again for your great works.

[@sunnyblount2319]

I see you categorized the break room and conference room as Assembly, but I thought if the room was less than 50 occupants it was categorized as Business?

[@archicorner]

Rooms and Spaces always get “occupant” load calculated per the use they are given. If a room is used for an assembly purpose then it must be calculated as such. That’s “occupant” loads. As far as “occupancy classification” goes, you are right, it would not be classified as an “A” occupancy, unless you reach 50 occupants. Thats a good question, be sure to separate “occupant” load from “occupancy classification”. 👍🏽

[@jma5282]

can't you just add all of the Business SF's together first and divide by 100 and get 5.3 in order to round up to 6 occupants? Instead of doing them all separately and getting 2 occupants for each office which gives you 8?

[@WizMoh777]

@@archicorner Got my answer 😂

[@Halfwheelhell]

First off, I love your videos, they are extremely helpful. However, I don't believe you round up for each office (as in if you have 120SF = 2 occ.) I also don't round-up people, and have had the opposite experience - most LBJ I have worked in allow rounding down for any fraction. You can't have half a person, you either reach a threshold or round down is my argument. I would also combine all offices together to 530 sf /100, not as individual spaces, but rather lumped together by singular use, 5.3 persons = 5 occupants. So although I found the rationale very logical I would calculate 5 occupants where you calculated 8. Actually since office space is all 100 SF / occ I woudl calculate all office and open office space together as singular load factor (1,175/100 =11) So the case of your storage room with 100 SF is also a point of argument, I suppose 1 occ. is the minimum, but I might argue for 0. As always very helpful, and I am not sure the code defines how to calculate as specifically as adressed by your video or my comment. Please correct if I am wrong! thank you!

[@archicorner]

That’s a good point. However, I have noticed that not all jurisdictions accept that, and plan reviewers sometimes ask for each office to show their occupant load. This is one of those scenarios where you must know what jurisdiction that you’re working with, and if they allow one method versus another. If your AHJ allows that then I don’t think it’s a big deal, go for it. There’s more than one way to skin a cat sometimes. Thank you for sharing.

[@mendaxadel3721]

How did you get storage room occupant load? Since it is only 100 sq Ft.

[@archicorner]

I am not sure what your question is exactly. You either have an occupant in the room, or you don’t. You can’t have a fraction of an occupant. Is that what you mean?

[@marianawassef7993]

Beneficial video! I am confused about the conference room. Why are they Assembly if they are less than 750 SF? the same for the breakroom, I understand that assembly group when you have more than 49 occupants or area that is more than 750 SF. Thanks

[@archicorner]

I think what you are getting confused with is OCCUPANCY GROUP CLASSIFICATION and FUNCTION OF SPACE. When determining occupant loads (don’t get “occupants” confused with “occupancy”), you must use load factors based on the function of the space regardless of the size of the room. Therefore, an “office” or “B” classification group may have rooms used for storage, assembly and office. All of which may be considered “B” occupancy but when the number of occupants is calculated for the conference room, the room is in fact used for “assembly” and therefore uses the allowed load factor for “assembly” use. hope this helps. 😊👍🏽

[@maryannchang]

@@archicorner According to 303.1.2, it states that "A room or space used for assembly purposes that is less than 750 sf in area and accessory to another occupancy shall be classified as a Group B occupancy or as part of that occupancy". I'm still a little confused. Can you correct me if I'm wrong, but I still believe the conference and break room should be considered as "B" occupancy.

If the occupancy group of this project is a business, and the factor is 100 GROSS? Why you divided each area with different factor?

[@archicorner]

"Occupancy Groups" and "Occupant Loads" are completely separate items. Occupancy Groups are defined in Chapter 3 and are used in Chapter 5 to determine (amongst other things) allowable areas, heights, number of stories, etc. Occupant Loads are determined by Chapter 10 and the primary objective is to determine egress requirements, such as number of exits, exit distances, etc. Check out Archicorner Episode 030. Let me know if this clarifies your question. THANKS!

Could someone explain gross vs net in the occupant load factor?

[@archicorner]

That is actually the subject of the next video! We hope to have it out by end of the month. Keep an eye out for it.

[@SeattleBDR]

Why not add all the Business Area square footage up first and then divide by the Load Factor? It would have divided out better and you wouldn't have rounded 0.2 up over and over again.

[@archicorner]

The main reason you show occupancy loads is to show how many people are egressing from a specific area. Depending on the occupant load some areas may need two or more exits. Since the load for offices is so small, it is reasonable that a typical 10x12 or 12x12 office may not need two exits. Therefore combining all the offices area into one occupant load may work fine. HOWEVER there are times when AHJ's may ask for the occupants load in a specific room to confirm that the correct number of exits are provided. Therefore it is a judgment call as to whether you use combined loads, individual loads, or a mixture thereof. Regardless of the method used, the key is to clearly show how all egress requirements are being met. Sometimes one method will be better than the other. GREAT QUESTION!

[@jules3543]

However NCIDQ's exams are based on the IBC and other commonly used standards by interior designers such as BOMA, ICC A117.1, NFPA, etc. The video you commented on specifically (AC 010) was produced with IBC in mind.
