1. Calculating occupancyload

Page 2: occupancy egress 2010 ERASE ME - ibiblio.orgibiblio.org/istudio/010/pop/pdf/10_2.pdf · In sprilklered the exits maybe more closet'/ spaced, Exit or exit- access be a minimum 01 one-third

Note:

Net & Gross areundefined terms.

Net: small areas(occupants area) – (buildingelements)

Gross: large areasfixed elements are used for area calculations – shafts orcourtyards

Occupant load =30’ x 40’ = 1200’1200 / 100 = 12

Occupant load =30’ x 40’ = 1200’1200 / 5 = 240

Occupant load =Number of fixed seats

Occupancy load =15’ x 15’ = 225Assembly no fixed seat = 7225 / 7 = 32

Occupancy load =15’ x 20’ = 300Assembly Unconcentrated = 15300 / 15 = 20

Occupancy load =(30’ x 40’) – (15’ x 20’) = 900Business area = 100900 / 20 = 9

Total design occupancy load = 32 + 20 + 9 = 61

2. Calculating number of exits and exit access

International Building CodeTable 1005.2.1

Total design occupancy load = 61Group B Occupancy. Table 1005.2.1 = if more than 50 then 2 exits

3. Calculating the locationof exit access

Trav el distance

Most occupancies have an allowable travel distance of 200’without sprinkler and 250’-300’with sprinkler
