30 Building Code Issues for Automated Parking Facilities Use & Occupancy Classification Access Fire Protection Ventilation

31 Use & Occupancy Classification Group S-2 Occupancy Classification for low hazard (non- combustible) storage. Section of International Building Code (IBC) applies to storage of motor vehicles. Doesn’t adequately address the special case of automated rack storage of automobiles in an unoccupied storage vault. Section 413 of IBC indicates high-piled stock or rack storage in any occupancy group shall comply with Chapter 23 of the International Fire Code (IFC). Storage of motor vehicles is classified as a Class I commodity.

32 Access Section of IBC indicates “Where no persons other than parking attendants are permitted, there shall not be less than two 36-inch wide exit stairways”. Chapter 23 of IFC requires a minimum of one access door in each 100 lineal feet of the exterior wall that faces the fire department access road. 24-inch wide aisles required for fire department access (i.e. ladders and catwalks).

33 Fire Protection High piled storage area greater than 2500 sf requires automatic fire extinguishing system. Maximum pile dimension equals 100 feet (between aisles). Maximum storage height equals 40 feet. Maximum pile volume equals 400,000 cubic feet. Type of construction: TABLE 503 (partial). ALLOWABLE HEIGHT AND BUILDING AREAS Group Type of Construction Fire Rating Type 1A- Three Hour Type 1B- Two Hour Type IIA- One Hour Type IIB- Non-rated S-2StoriesUnlimited1154 Allowable AreaUnlimited79,00039,00026,000

34 Ventilation Smoke venting at ceiling required. No ventilation of vehicle emissions required. Ventilation rate of 0.05 cfm per sf of floor area required (1/15 of airflow required for dispersing vehicle emissions).

35 Summary Automated Parking Garages provide equivalent capacity to a conventional, ramp-access garage in approximately half the volume. Automated Parking Garages pollute far less than conventional, ramp-access garages. Automated Parking Garages provide more LEED certification points than conventional, ramp-access garages. Automated Parking Garages should be designed as high- piled, rack storage facilities in accordance with the provisions of Chapter 23 of the IFC for Class I commodities.
