IBC Ch. 3 Occupancy Part 2 - ARE 5.0 PA

[@sanafadawi4788]

One point that resonated with me with me was the categorization of high-hazard occupancies, particularly the close attention to the types and quantities of hazardous materials. I found it interesting how the code splits hazard levels into subgroups (H1-H5), each with a different safety concern, such as detonation risks in H1 and health hazards in H4. This strict approach makes sure that buildings are designed to endure specific threats while protecting their occupants. The preciseness of these classifications highlights the value of meticulous preparation in hazardous environments.

[@joshyd.5169]

I agree about how the categorization is interesting when it splits into the subgroups and it is also interesting how it is focused not on the occupancy of the individual but the hazard level. It reminds me of a fire diamond in its organization and it makes the occupancy section stand out in my opinion. It's good that we're placing that amount of care into the safety of individuals when considering occupancy.

[@nestorpenagonzalez8096]

I found the breakdown of high-hazard occupancy groups really informative, especially how each subgroup manages specific risks like detonation and health hazards. It was also insightful to see how these classifications impact building design and safety in different settings. My takeaway from this video is how occupancy codes influence architectural requirements across various types of buildings, from hospitals to residential and storage facilities, which was super helpful to learn!

[@emilymendoza1169]

The insights provided by this video resonate deeply with contemporary issues surrounding safety in building occupancy. From what I gathered, these groups determine the level of hazard-particularly concerning high-hazard categories-and subsequently inform the architectural codes associated with hospitals, residential buildings, and storage facilities. This was very useful for grasping the protections associated with these different group types.

[@elysanchez857]

Going through the video and realizing how many different "types" of building there are is a little overwhelming but you break the categories down very well in the video. I have been exposed to the code in the past, but finally getting a full view of the major occupancy groups is very helpful because not only does it give me an opportunity to introduce myself to new occupancy groups, but it also reinforced the knowledge I had on the occupancy groups I currently work a lot with - Group R which is residential. I want to note that Accessory Dwelling Units are in the R-3 classification as well even though they are not mentioned in the CBC, but since I do most of my work with ADU's, Remodels, Additions, Alterations, and garage conversions in existing single family homes, most of these fall under the R-3 Clasification.

[@yiningli2920]

The video clearly explained the differences between occupancy groups and how letters and numbers relate to specific safety criteria, helping me understand the subgroups for groups H, I, M, R, S and U. I now understand that "H" identifies hazardous buildings. I also found it interesting how Group I is categorized by the occupants' ability to care for themselves in an emergency, or by the number of occupants and the time spent in the facility. Videos like this are really helpful in preparing me for my architecture studies, especially in understanding occupancy classifications.

[@DominicJarquin]

This video clarified occupancy groups, particularly the "H" codes for hazardous environments (H1-H5), each addressing specific risks like detonation or health hazards. I found it fascinating how detailed these classifications are, ensuring buildings are safely designed for specific dangers.

[@KatherineLujan]

The video clearly outlined the differences between occupancy groups, explaining how the letters and numbers align with specific safety regulations. It gave me a better understanding of the subgroups within H, I, M, R, S, and U categories. I found it especially interesting that each group had different subgroups making especially specific not leaving any room for loopholes or confusion to make sure everything is categorized correctly.

[@bellatorres8452]

This video was helpful because it helped me understand the importance of H (Hazard) and its subcategories, At first glance, I didn’t see them as particularly crucial, but after digging deeper, I now understand their importance for ensuring safety. I also appreciate how well-organized and structured these codes are, which makes everything much clearer.

[@jiunlichang0857]

This video explained the occupancy groups H, I, M, R, S, U and their subcategories, especially when it came to differentiating between Group I (institutional) and Group R (residential). I found it useful to understand how safety codes and the number of occupants in a facility influence the classification. The examples you gave about Group H (hazardous materials) were also great, especially with the breakdown of the subcategories H1-H5. It’s nice to see the detailed codes.

[@angeltrujillo4274]

As a continuation of the previous video, this one helped further clarify the differences between the 10 occupancy groups. I think it's really cool how you go into detail with explaining the rest of the groups such as H, I, M, R, S, and U. You do a great of breaking the occupancy groups down with the sub groups and referencing the CBC 2022 to show us exactly what it says. I think all of the occupancy groups are equally important but it's good to really take note of the Hazard groups since they represent the hazard levels of the building.

[@michellemelendez6876]

Something that resonated with me is the number of occupancy groups there are. It's interesting to see the categories of each and to think that every day we encounter different buildings that fall into the various different occupancy groups. This video has helped me further understand how I would go to classify any building type.

[@alkmoo]

The part of the video that resonated most with me was the section on occupancy with hazardous conditions. I didn't realize there were so many different, hazardous or dangerous conditions that could exist around a building, which in hindsight is a pretty naive mindset. I found it very helpful to show how broad the scope of architecture, codes and construction really is as I have been focused on designing interesting or appealing buildings. The section on occupancy for such conditions made me realize that there are many more conditions to take into consideration when designing not just an environment or terrain.

[@jimnguyen9102]

A point that resonated with me is how residential spaces are categorized based on the specific needs of the occupants. For instance, R1 is primarily about hotels/motels and the regulations take into consideration that the residents are only there temporarily and may not be familiar with the space, so the design must prioritize their safety in case of unexpected emergencies.

[@IsmaelCarrenoOrtiz-ek2re]

This video was quite useful in explaining the complexity of occupancy classifications. I found it amazing how a slight change in the number of occupants can shift categories, such as Group I-1 moving to R4 or R3, and the specific parameters for Group I-3 based on convicts' movement emphasize the significance of safety planning. Understanding these small but important things are critical for good building design; thank you for making such a hard subject more approachable.

[@elifzeynepcetin1323]

This video breaks down the different occupancy groups really well, especially the High Hazard Group H and its subcategories related to hazardous materials. I found it interesting how it differentiates between Institutional Group I and Residential Group R, particularly in terms of the level of care the occupants require. The examples provided, like nursing homes and prisons, helped me grasp the differences between the subgroups I1 to I4. I learned that facilities with over 16 residents can fall under I1, but if there are fewer occupants, they might be classified under R occupancy instead.

[@fluffyman76]

In this video I found plenty of new information that I have not learned beforehand. It really talked in depth about topics and classification for the groups of occupancy. One of the groups that stood out to me because I did not know it that much was the H or S category. At first when I was reading about it, it did not seem to be that impactful compared to everything else. Then as I kept understanding it more throughout the video I understood why it made sense.

[@quinlantobin2320]

This was a helpful video to point out the differences in occupancy groupings. A main topic that stood out to me was the importance of each number, and what they represent. The codes are all very specific, which I find important since we need to have the right construction laws regarding types of programs in order to optimize safety.

[@JustSun111]

This video did an amazing job at clarifying the various occupancy groups and explaining their distinctions concisely. I learned that each group such as the "I" group for institutional facilities is subdivided based on specific factors like the occupants' ability to respond in emergencies and the number of occupants. The detailed explanation of high-hazard categories (H1-H5) and their associated risks, from detonation hazards to health concerns, helps emphasize the importance of accurate classification to ensure the safety of the occupants.

[@sarqeles]

Awesome!

[@asadab9317]

This video was definitely helpful in understanding just how many different classifications fall under an occupancy group. I think it explains really well how these categories are differentiated and what they are used for. It will definitely be helpful when it comes to understanding the occupancy types of our own building designs.

[@nicolehaskul]

This video helped me understand the subgroups for groups H, I, R, and S. It is interesting how the subgroups are categized in group I by the abilities of occupants to take care of themselves in an emergency or by the number of occupants and how long they are spent in the facility. And the hazard group is something I need to carefully look over because of how the subgroups are categorized by the quantity and how hazardous the material is. These types of videos really help me understand the occupancy classifications and prepare me for my architecture studies.

[@aneesai241]

This video was very helpful in describing the differences with each type of occupancy, as well as explaining the differences within the subdivisions as well. Something that stuck with me is the differences and similarities between the residential R Group and the Institutional I group. Although they are different they share a lot of similarities in their categories such as how different types of adult care centers would be in different categories. This is something that I will practice more so I can remember the differences and not get confused.

[@JacquezA02]

One point that resonated with me was understanding the occupancy classifications, especially in institutional settings like prisons. This highlights the different levels of assistance required by the occupants during emergencies. For example, in Group I2 buidlings, like nursing homes, these building need extra assistance and safety protocols catered to the vulnerable population. It is highly important to understand these safety measures to protect those who need the help during emergencies.

[@anasofiabotero7141]

This video was super helpful as it really dove into many of the topics and classifications for many of the groups for occupancy. An occupancy group I did not know about was the H or S category, briefly looking at those two categories I wouldn’t see them as super necessary or important, diving in I have been able to acknowledge why it is important for H and S for the safety of others. I like how organized and structured these codes are it really makes it understandable to know the why behind some of these rules/restrictions.

[@liyahsalazar1587]

This video was super helpful. It explained the classifications for many of the groups for occupancy very thoroughly. I did not know about the H or S category for the occupancy groups, I like how organized and structured these codes are. It really makes it understandable to know the why behind some of these rules/restrictions.

[@LwinAung-g3c]

This video was helpful in clarifying the different occupancy group and how each group has its own sub-group. This shows the complexity within the codes as it deals with many different safety concern. For instance, Group H (Hazard) addresses the concern like a detonation hazard (H-1), while H-2 addresses deflagration hazard, which shows that buildings need to comply to these specific codes in order for people to occupy the space safely.

[@m2studiogroupadamaneesaerinken]

I like you go into detail about each occupancy group but then go further in depth on the subgroups and which buildings would go into each one according to what it would be in the actual building code. I think that's very helpful especially since you put into more manageable terms the complex intricacy of the CBC.

[@jackcox2700]

I like how this video goes into depth about the type of people occupying the space, and how that could possibly increase hazards. For me, the Group I (institutional) picked my brain the most. With my grandparents getting older, my family and I have looked into adult day care and 24 hour care homes, so it is interesting to see the CBC have exact numerical limits that differ the I-subgroups. Such as in group I4; this subgroup deals with buildings holding more than 6 clients for less than 24 hours, whereas group I2 deals with buildings operating MORE than 24 hours.

[@mzkadventurer82]

This video clearly explains check-in groups, highlights the 10 most common types, and uses memorable associations to distinguish them. It breaks down the collection (A) into subgroups (A1 to A5) based on space type, helping viewers understand how occupancy classifications like A, B, E, and F affect building design and use. The video highlights that community colleges are classified as having B occupancy rates, while K-12 schools are classified as having E occupancy rates. Anomalies such as religious classrooms and bookstores have also been clarified. Overall, it emphasizes the importance of careful classification to make complex concepts easy to grasp and remember.

[@gabrieltorres331]

Following the first video, it was easy to follow along and understand the different occupancy groups and subgroups. After learning about the Hazard Occupancy group, I was able to understand how crucial it is to know how to categorize the subgroup based on hazard levels and how the area is used. I also found Group I really interesting in how the groups are categorized and what conditions they are part of the Residencial group.

[@daliasandoval9406]

This video helped me learn the different type of occupancy groups and how to assign them in buildings and structures. I wasn't aware that the most utilized groups of occupancy consisted of subgroups. Such as Hazard having H1-H5, and each presenting different hazards like physical, health, or materials. This helped me gain better understanding on why its important to learn how to assign a group as it can affect individuals health or put them in risk. I will definitely look into the different types of material listed in Group H to better understand the pros and cons of them.

[@EthanEslamboly]

Expanding on the previous video, this one continues to be extremely helpful with occupancy. While learning about all the subgroups does seem scary at first, the way you break it down is really helpful with the understanding of what each one is for. Learnig what each of the letters mean (H for hazard I for institutional and so on), will really help in the future to avoid confusion and be confident that I know what I'm looking for and talking about.

[@armans.857]

In part 2/3 of the video series that covers the different occupancies, this part goes over the different occupancy groups between H-U. I appreciate the simplicity of this video in explaining these high-hazard occupancies. For example, Residential Group R-2, stood out to to me more because it is the most familiar as residential architecture is an area that I'm considering pursuing after education. Knowing the occupancy limits and subcategories around them should be a priority for me to fully understand.

[@sarahowainat7219]

This video provides a valuable overview of building classification and occupancy groups, which are essential for ensuring compliance with building codes. It’s great that it promises to equip viewers with the skills to classify any building type. Including practical examples or case studies could enhance understanding even further.

[@nessa2862]

I thought this video provided insightful and helpful explanations of the occupancy groups, especially when going in detail of the subgroups for H,I,R, and S groups. It was interesting to learn about the categorization of the high hazard group H that each involve different quantities and types of hazardous materials allowed in a certain area where buildings are designed to withstand potential hazards. It’s important for architects to have a thorough understanding of the types and quantities of hazardous materials that will be present. This knowledge helps in determining the appropriate safety measures and building features required in order to protect occupants in the building.

[@TabarekAldabbagh]

When answering the question at the very end I found myself a bit lost. I knew it would be residential but each specific description wouldn't exactly match what the question was asking for. I couldn't find "100 dwellings" in any of them, but then I realized, they didn't always run by a maximum number of dwellings, and R2 specifies that it is for 2 or more dwellings, such as hotels and dormitories. Those examples helped me put together that 100 dwellings is technically more than 2, which meant it was included in R2 occupancy classification.

[@oliviaedmonds6232]

The letter categorization system makes understanding and remembering occupancy types much easier. Breaking down categories like Hazard, Institutional, and Residential into subcategories based on specific factors helps clarify where each building falls and ensures that developments are safe and fit for purpose.

[@laurenf3100]

It's really interesting to see why the occupancy groups have been categorized the way they are. For example, residential being classified that way because people are sleeping in these buildings makes perfect sense but I wouldn't have thought of that initially. It's also interesting to see how specific the hazard and storage groups get, like seeing the examples of S-1 might be storing canvas and cloth while S-2 might be storing cement and chalk.

[@spencersalcedo2603]

This video provides a helpful breakdown of building classifications based on the building code, focusing on the correct assignment of the occupancy groups. One key point is understanding how different occupancy types reflects the buildings intended uses, such as Hazard (H), Institutional (I), or Mercantile (M), which directly impact safety regulations. Being able to understand these distinctions can ensure your compliance with local building codes, especially when determining fire safety or egress.

[@taj9257]

After wathcing this video, I have greatly appreciated the explanation of each category. The high-hazard categorization I have now realized is a very important catagory to implement. How well these facilities respond to these different hazards is vital, as each emergency/ or hazard has different requirements and effects!

[@rekelsherrett9298]

It was interesting getting a further breakdown of the 10 occupancy types. The Miscellaneous U category I found particularly interesting, who knew barns, carports, and aircraft hangars didn't have a category of their own. Another shocking aspect was definitely the breakdown of sections H1-H5. The grouping of hazardous materials and classifications was something I hadn't realized or thought about before.

[@natalysegundo5682]

This video helped me in my understanding of the 10 different occupancy groups and their subcategories, if any. A point that particularly resonated with me was the Hazard, Group H. I learned that there is an Occupancy group for buildings that handle hazardous materials in excessive quantities. H1 includes detonation hazard, H2 is accelerated burning, H3 deals with buildings and structures supporting hazardous material , H4 is health hazards and H5 deals with the production of hazardous materials. Just learning about the different types of hazards that exist was intriguing to me but learning what category they each belong in was useful.

[@jiachengzeng656]

Through this video I learned that the codes for different materials can protect us better, so we must be aware of the different codes when we do our design. In this video, I had some doubts about the I-4 and R-3 categorization, and whether their difference is that I-4 is only for a certain period of time, while R-3 is permanent. The interesting thing to me is that this video is still very helpful in furthering our understanding of the different professions.

[@shaylagutierrez4540]

This video clearly explains different occupancies and how the differences can sometimes be very small. It is cool to learn how thorough the book is. An example being when it specifies that group H-4 covers both highly toxic materials and toxic materials.

[@rileym.6691]

The institutional occupancy subgroups are sorted based on the occupants' ability to take care of themselves in the case of an emergency. This isn't something I had previously considered would be an occupancy type, but I think it is very important since some people would need more help. I thought it was interesting how I3 consisted of places such as a jail where the occupants are detained, but I2 is places such as hospitals where occupants may be injured. Both groups are for occupants in different situations, but I appreciate that the building code takes into account everyone's safety, including those who need extra assistance in the event of an emergency.

[@yeseniadiaz-h9l]

Something that I found interesting was how the occupancies are grouped and how specific they can be. Where each code really has a different hazard that it is classified by. For example, one that stood out to me was when you mentioned how there are groups that focus on materials that are a physical hazards and ones with health hazards. This just really goes to show how specific the occupancies and different groupings can get, and it made me wonder how they would differentiate what hazards would be considered just a health one and not physical because at times your health can affect you physically.

[@DylanHoron]

Finishing up the 10 most common occupancy types, the rest are able to be explained in the same manner of letter categorization that makes it easy to understand and remember. Categories such as Hazard, Institution, and Residential have sub-categories that are explained well in what makes them under a specific number. Understanding these occupancy types is definitely helpful in developments of a building so that we know what can be placed exactly where it's safe.

[@ikonikbtw6420]

I found this video very useful; I didn't know that hazards had subgroups to them, I thought that they fell into one group, but I see that the different subgroups of H1-H5 explain the risk in different ways. I liked how the S group or storage group was presented because it made more sense when talking about the high vs the low hazard for the subgroups which explained how to depict which subgroup it is with. I liked how the Institutional, Mercantile, Residential, and Utility groups were broken down and a bit simpler than the storage and hazard groups. The groups of storage and hazard were something that I had never thought of, and they both were a bit more complicated than the rest, but this video helped a lot.

[@katelynguyen7746]

I learned how specific building codes can be in order to guarantee safety and efficiency. I never knew how number reliant it was. One point that resonated with me was that a building's classification can change due to amount of occupants. For instance, if there are more than 6 day-care occupants at one time, it is in group E; however, if there are 5 or less, it would be categorized as R3.

[@ezequielduarte8263]

Within the different occupancy types covered in the video there were some that stood out to me the most. Some being both Institutional and Residential, because before watching this video and learning about occupancy types I would assume that anything related to residential would follow under the R type yet within the I type group I1 it states "if more than 16 people who are living supervision in a residential environment on a 24-hour basis", yet by knowing these is that we as architecture students and those who are architects can differentiate them and other occupancy types to further limit errors as well as casuing financial setbacks.

[@nicolepalacios5687]

Hi! you mention an important realization about the distinction between Institutional and Residential occupancy types, which can easily be misunderstood without proper knowledge. The example of I1 occupancy, which applies to residential environments where more than 16 people live under supervision, shows how crucial it is to understand the details. As architecture students or professionals, recognizing these differences is key to minimizing design mistakes and avoiding financial setbacks.

[@jasonliu9169]

This video was helpful for understanding how to differentiate the various occupancy groups. I was able to understand clearly the meaning behind both the letters and numbers of each occupancy group. I believe that the difference between high toxic and toxic materials is that toxic materials are dangerous goods while high toxic materials are toxic and reactive.

[@andrewkim1461]

The video contents are so clear and helpful for me to understand how codes are divided. It is interesting that Hotels and Motels are in different categories from residential houses because occupants are not familiar with its surroundings so it should be designed differently. That was such an interesting thing to know. I wish I had known it earlier so I can have a better understanding of buildings and categories.

[@juliealtamirano6180]

This video was super helpful in explaining the different occupancy types and how each one is tied to the specific use of a building. I found it interesting how much detail goes into categorizing them. Even though some of these subgroups seem really similar, the video did a great job making it clear, especially since these distinctions are important for the safety of the occupants.

[@samueljimenez2225]

I found this video very helpful in clarifying the differences between occupancy groups and explaining the meaning behind the letters and numbers in each group, such as how the "H" groups represent varying levels of hazard. I learned that high-hazard occupancies are categorized into subgroups (H1-H5), each addressing specific safety concerns, like detonation risks in H1 or health hazards in H4. This detailed classification system ensures buildings are properly designed to handle specific risks, highlighting the importance of careful planning in hazardous environments.

[@victorbuschaud7035]

The remaining occupation types and how each category applies to a particular building depending on its intended use were both explained in this video. Occupancy Type R is classified as a sleeping area and is further subdivided into four groups based on the number of residents and whether they are permanent or temporary. Given that they are focused on guaranteeing occupant safety, it is natural that these distinctions are very precise.

[@johannaaquino5601]

One point that resonates most is the importance of safety regulations because there are a lot of potential dangers. The H group classification includes those buildings that pose significant fire, or even explosion so knowing about this group and subgroups is crucial for protecting the occupants.

[@moseses3414]

An interesting point I found in the video was that dry cell batteries are classified in the S-2 group, which includes non-combustible materials. This classification stems from the belief that lithium-ion battery fires are difficult to extinguish and have a high potential for explosion, which would typically place them in at least the H1 group.

[@elainehung1592]

I think that I resonated with the categorization of different buildings. It is interesting to learn how many subdivisions each group has based on various factors. For example, there are 4 subgroups within institutional group I. I found it interesting that they are divided based on the abilities of occupants to take care of themselves during an emergency, number of occupants, ages, health, and how much time they spend in the facility.

[@Shawtyyaa]

This video amazed me, at some point, I was getting overwhelmed how many subgroups a group has. It’s such an important topic as a designer, due to keeping everyone's life safe. I believed hazards were considered one group only, yet this video taught me how there’s subgroups that distinguish different scenarios and materials. For example, High-hazard Group H-3, takes care of structures and buildings that contain composition and physical hazards while Group H-4 focuses on health hazards in a structure and building such as toxic materials. As future architects, this is a crucial lesson, one must learn and carefully assign occupancy groups to avoid conflicts.

[@sarqeles]

Glad you found it helpful!

[@ClaudiaGonzalez-dq3px]

This video, in addition to part 1, helped me to further understand the reasoning behind having different occupancy groups. This helped me realize how at the end of the day, it's all really about safety, and how all these very specific rules and subcategories really determine a building. It was also interesting to me how just by adding more people into a building, it completely changes its occupancy group; such as how by having more than sixteen occupants in an assisted living facility or group home changes it from being a R4 occupancy to an I1 occupancy.

[@kaylayeie]

I found this video very beneficial as it helped clarify the difference between occupancy groups. This video also clarifies the meaning of the numbers and the letters in each occupancy group, so now I understand that groups with the letter H represent the hazard levels of the building. The indication is helpful for noting what environments are hazardous and what steps need to be taken before construction can begin, or what types of construction can even exist in the area.

[@adrielrivadeneira7560]

I found this video very helpful in understanding how the occupancy groups are subdivided into subgroups. The part of the video that really stood out to me is how group R4 is not under group I because group R4 is mostly residential care facilities which is what group I is all about more specifically group I2 (nursing homes).

[@FerialDagher]

Something interesting about these occupancy types is that the Insititutional category can encompass so many different types of facilites. Conceptualizing inmates as inhibited or in need of supervision in a way that parallels care homes for elders or patients in hospitals speaks to an interesting view of what it means to be 'self sufficient' and what spaces exist to aid people who aren't deemed as such.

[@jasv17]

This video really helped in understand the subtle differences in occupancy classifications. The differences between some of the groups are small and seemingly unimportant but actually have a big impact on the specifications of the space. For example, I thought the distinction of a place where residents are temporary as opposed to more long-term has an impact on the layout of the building, having to take into account a level of unfamiliarity in the event of a crisis.

[@costascastillo3226]

I found that this video was very helpful for clearly defining each topic and classifications for the different groups of occupancy. I did not know that how deep each category could be subdivided for the specific use of occupancy, I had believed the classifications to be more generalized, but interesting and helpful to learn that it is more precisely defined. The explanation in the video really helps to easily learn the topic and focus on the most important aspects of this concept.

[@nikanayer3787]

I found this video incredibly helpful in clarifying the different occupancy groups and their meanings. For instance, I now understand that groups like H represent hazardous environments, which is crucial for safety and construction planning for dealing with hazards like toxic and flammable materials. I loved learning about groups like H, R, U, and I, which aren’t discussed as much but are really important. Group I-3 was particularly interesting to me because it covers high-security areas, and I have always wondered how they determine occupancy for places like jails, where there are lots of people in a confined space.

[@sarqeles]

Awesome!!!

[@jacklam4856]

This video helped me further understand how occupancy is categorized and the organizing system that is used to identify the groups. I like the method of using letters and numbers to identify which level the building is classified as. An example of this is H1 meaning it is hazardous and has a detonation risk while a building that is considered H2 is at risk of accelerated burning. Overall the video was interesting to learn from.

[@NathanWoodmansee-f3x]

The video helped explain each occupancy type and classify it with real world buildings, which sometimes only differ slightly but require vastly different occupancy types. This stringency helps maintain order within safety codes primarily for fire response, and helps designate hazardous buildings to zoning away from public and residential spaces.

[@FigenCosta]

It's very interesting to learn all about the different sub categories, especially about the institutional group I-3, which includes detention facilities and jails and how that is separate from I-2 (hospitals, nursing homes etc) as they can not respond to emergencies because of physical reasons but due to security measures and them being detained. I also didn’t realize there’s a specific category for storage, and that S1 and S2 are based on whether the products are combustible or not.

[@EmilyJust-nt4kh]

This video was also helpful when talking about the remainder of the occupancy types. The residential type seemed easy to understand because it was for sleeping purposes but the part of hotels/motels having different codes due to people being unfamiliar with the building was interesting. Some of the other categories seemed pretty straightforward like institutional and mercantile but I might need to review the subcategories to fully understand all the information and separations.

[@khabib2037]

One point that resonated with me was how the abilities of an individual responding to an emergency with or without assistance dictates what group is categorized as. Specifically the Institutional Group I. I also did not consider that the categorization of a prison was dependent on the nature and abilities of freedom of images/occupants. I assumed that because the space is a facility with institutionalized sets of rules would be the deciding factor. It was mentioned in the video that prisons on its own are subdivided into nine conditions based on freedom of movement inside a facility. I am interested to see what the different levels entail.

[@blossomjolene5274]

A point that resonated with me in the video is the emphasis on the high hazard (H) occupancy classifications and their critical role in ensuring safety in buildings that contain dangerous materials. The classification of high hazard occupancies into five subgroups (H1 through H5) reflects the need for strict regulations based on the nature and quantity of hazardous materials, such as flammable liquids and toxic substances. This careful categorization is essential not only for compliance with safety codes but also for minimizing risks to public health and safety. By understanding these classifications, architects and designers can implement appropriate safety measures and design strategies, ultimately safeguarding occupants and the surrounding community from potential hazards associated with high-risk materials.

[@ramananganesan6659]

This video was extremely beneficial in separating the different occupancy groupings. from group H-U. One thing that I understood from this video was thee importance of specific numbers. For instance, the number of kids a daycare facility might have could change the first level grouping completely, from one letter to another. The groupings are very specific, and I believe it important to look for such details when trying to categorize a building into a grouping.

[@ryleetoma5271]

I found it interesting to learn how the high hazard group H is categorized based on the types and amounts of hazardous materials permitted in a space. I also think that it was interesting to learn that there are some classifications that differ based on small details or minor changes. For example, 1 occupant can change a group from E to R3.

[@serayun1188]

I find it interesting how Residential Group R and Group I are divided, especially the difference between people who can help themselves in an emergency and people who need help because they are physically disabled or have limited freedom. Group R/3 includes a lot of homes in the suburbs, while Group R/2 includes flats. It's also interesting how the dangerous materials are grouped: Group H is for dangerous materials and Group S is for non-hazardous keeping. It's interesting how specific these usage groups are, especially when it comes to telling the difference between health and physical hazard, which often go hand in hand.

[@dianalicea3384]

Occupancy groups H and I seem to require a lot of research into the codes to avoid the incorrect category. As stated in the previous video, it is very crucial to go through and evaluate the entire code because once you're in the section, it provides enough detail to help with any questions that can be pending. Also, taking a look at the table in section 307.1 was easier to understand once you have it in front of you and how the table breaks down the quantities of materials.

[@kailanisimms44]

I found the hazard groups particularly interesting. It makes sense to have different subcategories, for example H1 classifying detonation hazards and H2 classifying flammable hazards. Before, I would have thought they would have H without subcategories and just label everything that falls under as a general hazard to public safety, but it makes sense to have more specific explanations.

[@AllisonEllenburg]

The video was super helpful and clear about the different occupancy groups. From my understanding, these groups regulate the Hazard (which talks about the high-Hazard groups), then lead more into the architectural codes (based on hospital insinuations, as well as residential and storage). This was super helpful when it comes to understanding the protection that comes into play with these group types.

[@KeylaJimenez-b1v]

After watching this video I would say that between part 1 and part 2 the occupancy groups that really caught my attention was group H and group R. Group H has a lot of subgroups that need to be covered, and I think that it has more due to the fact that when designing this is the number one thing that needs to be looked at many times. As for group R I wouldn't have thought that there were subgroups for the residential group.

[@kennedyle683]

This video really helped in understanding more of the different types of occupancy groups. I did not know there were so many subgroups that go over each occupancy imaginable. There are many subgroups for many specific "rules" such as "more or less than six persons" that I never really thought about.

[@AngieHormaza]

I find it very interesting how residential group R and group I are categorized. Important to make the distinction between the people who can and are capable of helping themselves in an emergency and those who need assistance. Whether that assistance entails restricted Liberty, or physical disability. From my understanding, R/3 seems to be the most common when considering suburbia and R2 is apartments. The method of storage for hazardous materials is also intriguing as Group H is its own thing compared to Group S which is for nonhazardous materials and the difference between combustible and non-combustible storage and code

[@votrexx1352]

I think a very interesting point that was brought up in the video was the just how detailed the high hazard group is separated. from the detonation risk to combustible risk.

[@GershwinMason]

The institutional and residential were not as appealing as the storage and hazardous groups. I liked these ones more just because of my association with hazardous, that sort of category intrigues me, and learning some of the specific hazardous spaces in designing was interesting. It was weird to think of a barn as a storage/hazardous space but it definitely makes sense. H1-5 were really good to know because these are the occupancies you have to pay the most attention to since they can cause severe issues like combustion, ignition, explosiveness, toxic materials that lead to health issues,

[@monicarico8074]

What stood out in this video was the residential categorization. I seems obvious that a residential space would involve a place for someone to sleep, however, the distinction between how many units there are and how often users stay there seems like it can get fuzzy when trying to distinguish what a project is. It can take only one person to change a project from one category to another.

[@sarqeles]

Yes, codes are meant to reference. Never memorize.

[@panteasafiee]

This video was helpful in breaking down the rest of the occupancy types and how each group covers a specific type of building based on its use. It's interesting that so much detail goes to categorizing buildings. For example, occupancy type R, is for sleeping purposes but there are four groups based on the number of occupants and whether they are transient or permanent. These groups are very specific which is understandable as they are based on the safety of the occupants.

[@joeyvan8863]

Talking more about the codes by their letters is really interesting to me because now I am learning about the H codes. I wonder why I was never told about this when learning a bit about occupancy codes because I felt it is very important to understand why we have different codes for the different types of hazards such as toxic materials and flammable hazards. However the one I really enjoyed being informed on for the occupancy codes was code R. As someone who finds enjoyment in almost anything residential related, it was nice to know that motels, hotels are made for people to feel comfortable and understand that they are in a new environment so they are made to be created in a way of comfort. Also it is nice to know that these rooms are made to be simple and understanding that the occupant in the room can understand what and where everything is as they are going to be staying in that room for some time.

[@sarqeles]

Multi family vs single family housing have very different life safety requirements, glad you picked up on that distinction.

[@alfredtrujillo6750]

A point that was intersting to me was the way the specific occupancies are grouped. More so how each code has a different hazard that it was classidfied by. For example Group H-3 was focused on materials that were a physical hazard. For Group H-4 the materials were a health hazard rather than a physical one. The different levels within each occupancy show how each building is designed to meet each requirement based off the use and purpopse of it.

[@chiehchi8774]

In this video introduced the group H to U, which included most of the school project needs. This video explained the building purpose and number of occupants in each occupancy group clearly. I finally clarify the differences between R-1 to R-4, I used to thought R-1 meaning one building on the site and R-4 can build 4 structure in one site. Thank you for making this video, it is very helpful.

[@sarqeles]

You're welcome!!

[@lucasvargas1735]

This video is incredibly helpful, and I wish I had known this information sooner. While I understand that the codes can be overwhelming for incoming architects, I think it would be beneficial to be provided with a general overview of key codes-beyond just general safety, like egress and proportional circulation for ADA compliance. These considerations significantly impact design and can actually enhance it, making it more realistic and providing a better understanding of the overall process.

[@ErinCrane-tj9vx]

This video was also very helpful like the last part where I love how in detail you explain each category and what is and is not a part of the group. I felt that some parts of the group I was a bit confusing because it is hard to differentiate the differences in each section, but the video does a great job explaining the differences. I felt that there were a lot of similar categories in this video which made it a bit hard to remember which one was which but the video still was very helpful in differentiating the differences.

[@aracelyavitia3623]

This video is very helpful since it gives us more information about the occupancy types. Since there are more subgroups in the occupancy types, these seem more specific and similar when deciding what the occupancy is. Even though they seem similar it was explained very well.

[@sindimateo3606]

The group that I found interesting is group H which I did know it would exist which I think it is helpful to keep this material into one category but not that but also have subcategories that help to be more specific when it comes in handy.

[@fabiancuevas3450]

The most resonating part of this video was how certain categories can start to balance a thin line between each other as well how certain buildings fall under the same categories. For example, it was interesting to see that prisons and daycares fall under the same institution category and are only one category away from each other. On top of that, it was also interesting to see that an R3 residence could also qualify as a childcare business as long as the amount of children in the day care fall within the parameters of the R3 categories.

[@SamanthaAllenYoutube]

The question at the end truly made me go back through the video and think about how I would classify a 100 dwelling unit building. The question then raises one more: Are the expected residents meant to be transient or non-transient? A dwelling constitutes the assumption of a residential classification, however then the line begins to blur. R1 and R2 would both be suitable classes for this building, however there remains a clear distinction between the two and that is the transient or non-transient state of its residents. It makes me wonder how discrepancies like these might be solved in the workplace. Would a firm simply design with whichever classification is the strictest?

[@nat4860]

Overall, the quality and information in the video is very impressive and has definitely become a video I will constantly come back to in order to study for future assignments. I've learned in depth the different groups such as group "H," which would be the most interesting group due to how detailed hazards can become, creating specific codes for buildings depending on their occupancy and safety concerns. I do agree with what you said about the highly-toxic materials and toxic materials, it is pretty funny seeing how there are two forms of toxic materials even though any toxic material seems very dangerous.

[@sarqeles]

You can save videos for "Watch Later" or create your own playlist on KZbin for future reference.

[@jocelynrios555]

I think it's kind of interesting that there's no specific group for buildings like agriculture or stables for livestock, and that they're just put in with other miscellaneous structures. I wonder if this is partly because they might be semi-outdoor structures? I like that this video makes all of the subcategories for each group clear though, especially when it comes to knowing what what type of building can deal with things that are dangerous, like hazardous material or criminals. Having these categories is important for everyone's safety.

[@sarqeles]

Less of a safety Hazard for humans, everything is categorized based on life safety!

[@nickcrowell9164]

The institutional category was the most intriguing category during this part. It was very interesting how the grade is determined by how the users can respond to an emergency in time. What made it more layered is that category I2 responds to how the occupants cannot respond to an emergency without help form staff like hospitals and nursing homes. While the I3 category, the users cannot respond to emergencies because of their incarceration and being under security measures.

[@hirotoshigeta3596]

One point that stood out to me was about the occupancy group U. There are some question that came up to my mind as, can group U buildings be part of mixed-occupancy buildings? These buildings are typically not intended for long-term human habitation and often serve functional or supportive purposes on a property so it's a type of building that you don't see often and that's what made me interested in this group.

[@sarqeles]

Mixed occupancies can be any combination as long as its allowed by code and you meet all the requirements. Notice the types of structures in a U occupancy. Code writers cannot possibly create every type of code group or it would be pages long. Combining the groups according to similar life safety requirements is the goal and as long as its a mixed occupancy and you can prove you meet things like area, height, stories and how you choose to treat that U occupancy, you can combine with other occupancy types.

[@AldoGamboa-xg6km]

this video was very helpful, there is a lot of important information and I find it somewhat difficult to remember what specific number of occupants will change the occupancy type. For example for group I-1 where people can respond to emergencies on their own yet if there are less than 16 occupants then it can also fall into R4 occupancy and if there are less than 5 it can fall into R3 occupancy. I also found it very interesting how you mentioned that group I3 is divided into 9 conditions in the CBC based on how much a prisoner can move within their cell and can become capable of self preservation.

[@kayhanvasseghi9396]

I completely agree with your observations about the video. It does a great job of highlighting the complexity of occupancy classifications, especially how a slight change in the number of occupants can shift categories, like with Group I-1 transitioning to R4 or R3. This detail really emphasizes the importance of understanding these nuances for effective building design and safety planning. I also found the division of Group I-3 into nine conditions, particularly intriguing; it underscores how critical it is to consider individual circumstances in determining safety measures.

[@AndrewLemetti]

Great Video! I know this may sound strange but I never really thought that the definition of a residential was a place to sleep. I know it seems obvious but I thought it was related to where people live and their place of security. But it makes sense that the main distinguishing factor is "Is this person sleeping there or not?" Meaning there is a similar code between hotels and regular houses. That little definition was quite clarifying.

[@sarqeles]

It boils down to what kinds of things are people doing and how do those functions plus their own abilities allow them to escape or not ...in an emergency when the worst case scenario happens?

[@keanaangeliquemallari3125]

Something that resonated with me in this video was the many subgroups there are for each of the ten categories of occupancies. I found it interesting how H4, as you mentioned, mentioned highly toxic materials and toxic materials as two separate categories. It makes me wonder what are some examples for each and how big of a difference there is between highly toxic and just toxic objects.

[@sarqeles]

Excellent question. The difference in the types on materials are listed in those same chapters for each group or reference other sections that list what materials are considered under each H Group. @ryancarrillo558 ccd since you also asked a similar question.
