. . ionuscMu�oeooK other miscellaneous spaces ere occupied, they are occupied by the same people who are at other times occupying the cless- rooms. As a consequena, it is general practia that the individu- al occupant loads of the separate spacu not be added together in calculating the total occupant load of the building. It should be noted that the code contains no occupant load factor for calculat- ing the number of persons that must be considered to be prcsent in such a space as a comdor or in other spaces that actuelly wnstimte part of the ezit system. Similerly, some building officials take the same approach in calculating the totel occupant load of an office building end do not ascribe additional occupants to comdors, rcstrooms, storage rooms and othu miscellaneous spaca. In cenain instances, it is appropriate that confcrcnce rooms or minor assembly aceas, such ac lunch rooms in office buildings, also be cansidered as accessory spaces if they erc, in fact, occupied by persons who at oU�er times occupy the grneral o�ce arca. The code establishcs this approach es a legitimete method of detem�ining occupant load. The key, however, lies in Itie ability of the building official to conclude that in lhe actual uu of the building or the respective building spaces, they ere not in fact fully occupied simulta- neously. Having concluded that, it is endrely appropriate that the accupant load of such spaces not be included in the total building occupantload. 1003.2.2.2.2 Aeras witMout lixed seats. The occupant load that can be expected in different buildings or use spaces depends on two primary fac[ors: the nature of the use of the building space and the amount of space devoted to tha[ particular use. Differcnt types of building uses have a variety of cheracteristics. Of pri- mary imponance is lhe density char�cteristic.'R�ero(oro, in cal- culadng the occupent load of uu areas by means of the formula, the minimum number of persons that must be assumed to occupy a building or poction theroof is detertnined by dividing the ama devoted ro the use by that density characteris6c, or occupant load fectoc The third column of UBC Table 10.A pre- scribes the occupant load fac[or to be used with the rospective corresponding uus listed in the first column. As explained in Footnote 3, the occupant load factor does not represent the amount oC area which is required to be afforded each occupant. The Unijomt Building Code does not limit, and hes ncver at- tempted ta limit, lhe maximum occupant load on an area basis. Ra�her, the occupant load factor is that unit of area for which Ihere must be assumed to be at least one person present. Fur example, when the code prescribes an occupant lo�d factar of 100 for office use, it is not saying that each pecson in the office must be provided wi�h at least 100 squere feet (9.29 mz) of area. Rather, it is saying that at least one person must be assumed ro be present for each 100 square feet (9.29 mz) of floor area in the oCfice use. The tloor area to be used in occupant laad celcula- tions is that floor area defined in Section 207 with counter. and showcases in retail stores, fumiture in dwellings, equipment in i'I fumi ' alread � t e' o ac w' t�h acup nt load fectors in Table 10- , ierefore, the gross area of the space should be usod in the determination of the occu- pantload. u mbers contained in the third column of Table 10-A rcp- resent those density factors that rcprcsent the probable densities that can usually be expecrod in azeas devoted to the respective uses listed. For this purpose, these occupant load fectors are really a mcans of estimating the probable maximum density in �se � the rcspecdve use eteu.11iey have ban developed over a pqi ad of years and, for the most part, have been found to mnsistqr ly represent the densities which one might expect in build�q spaces devoted to the rcspective uses. Warc6ouse occupant load. The rcason for a larger occupq load factor for werchouses than for storage areas and stoci rooms is that in very' large faciliues used primerily for srone purposes, panicularly those which ere automaeed, the density � occupancy is less Ihen thet generally experienced in smdp storege arcas or in spaca frequendy �eferted to as stockroo� 'Ihe latter are frcquently incidental to other uses end are ofle more densely occupied. Foomote 5 wes added ro reflect tly even the higher occupant load factor that is assigned to wan houses will often result in an occupant load that is not resonabl for the mechanical-access high-rack storage systems. Occupant loads in mixed/muldpk ux bu0dings.'Ihe de temtination of occupant load is relatively easy when the build ing ccntains a single, continuous use. However, in the rq wodd, this is often not the cau. Many buildings containmon than one use or a combinadon of usa. Also, many buildings �n used for differcnt pucposes or different uses at differcnt tima All of this must be considered when calculating the maximuo number of people that might be expected in a building or build ing space. It is the maximum occupant load obteined as a�ad of these several variables that will be the occupant load that dic tates the requicements for the design of the egreSs system Obviously, the exiting system must be adequate to accommo date the maximum number of persons that results from the ua that will produce the greatest density. Wherc two or morc oxu pancies or uus occur in the same building, U�e occupant load o the separate uses must then be combined to determine thc tan occupant load of the building. Occupant loads when thece are vaciatlons ot use. An addi tional factor frcquently involved, probably most often in Gro�q A Occupancies, is lhat the assembly ereas, in addition to bei�q subject to different kinds of assembly uus, are also frequent� arranged so that the floor aroas can be uud in differcnt spatu artangements. Typically, in a hotel, far example, the grand bd1 reom will be divisible by folding pactitions or other method into various combinations of smallu spaces by manipulating �! folding partitions.'Ihis sometimes presents a difficult probkd in determining the ultimeie maximum occupant load for whid the exidng systems must be designed. In order to do this, it w necessary to consider all the various acrengements or combiw tions of spaces that can be created by using the dividing pera dons. This is complicated by the fact that within those variae anangements of spaces therc can be a variety of differcnt typb of uses that will have different cecupant densides. The building o�cial must ascertain that anangement of sp�u roupled wi�h the types of uus that would be anticipated to deter mine whet the maximum occupant load would be and to ensun that the reqaired safe egres's system is designed accordingly I', is important that each possible artangement of space, when usa for that purpose which will produce the greatest number of p� sons, be pravided with its own individuel exiung system. From the infortnation above, it is apparent that in cert� occupancies the ultimate detem�ination af occupant loads, ocp! pancy densities and euiting systems can be fairly tcdious. It tl essential that this be completely enalyzed end that a safe exidd
