Section 1305 — SCORING AND EVALUATION

The evaluation shall be composed of three categories: fire safety, means of egress and general safety, as defined in Sections 1305.1.1 through 1305.1.3.

1305.1.1 Fire safety. Included within the fire safety category are the structural fire resistance, automatic fire detection, fire alarm, automatic sprinkler system and fire suppression system features of the facility.

1305.1.2 Means of egress. Included within the means of egress category are the configuration, characteristics and support features for means of egress in the facility.

1305.1.3 General safety. Included within the general safety category are the fire safety parameters and the means of egress parameters.

The evaluation process specified herein shall be followed in its entirety to evaluate existing buildings in Groups A, B, E, F, M, R, S and U. For existing buildings in Group I-2, the evaluation process specified herein shall be followed and applied to each and every individual smoke compartment. Table 1306.1 shall be utilized for tabulating the results of the evaluation. References to other sections of this code or other codes indicate that compliance with those sections is required in order to gain credit in the evaluation herein outlined. In applying this section to a building with mixed occupancies, where the separation between the mixed occupancies does not qualify for any category indicated in Section 1305.2.16, the score for each occupancy shall be determined, and the lower score determined for each section of the evaluation process shall apply to the entire building or to each smoke compartment for Group I-2 occupancies.

Where the separation between the mixed occupancies qualifies for any category indicated in Section 1305.2.16, the score for each occupancy shall apply to each portion or smoke compartment of the building based on the occupancy of the space.

1305.2.1 Building height and number of stories. The value for building height and number of stories shall be the lesser value determined by the formula in Section 1305.2.1.1. Section 504 of the International Building Code shall be used to determine the allowable height and number of stories of the building. Subtract the actual building height from the allowable height and divide by 12.5 feet (3810 mm). Enter the height value and its sign (positive or negative) in Table 1306.1 under Safety Parameter 1305.2.1, Building Height, for fire safety, means of egress and general safety. The maximum score for a building shall be 10.

1305.2.1.1 Height formula. The following formulas shall be used in computing the building height value.

Equation 13-1 Height value, feet = (---------------------------------- [AH] ) – ( EBH - ) × CF 12.5

PERFORMANCE COMPLIANCE METHODS

Equation 13-2 Height value, stories = ( AS – EBS ) × CF

where:

AH = Allowable height in feet (mm) from Section 504 of the International Building Code .

EBH = Existing building height in feet (mm).

AS = Allowable height in stories from Section 504 of the International Building Code .

EBS = Existing building height in stories.

CF = 1 if ( AH ) – ( EBH ) is positive.

CF = Construction-type factor shown in Table 1305.2.6(2) if ( AH ) – ( EBH ) is negative.

Note: Where mixed occupancies are separated and individually evaluated as indicated in Section 1305.2, the values AH, AS, EBH and EBS shall be based on the height of the occupancy being evaluated.

1305.2.2 Building area. The value for building area shall be determined by the formula in Section 1305.2.2.2. Section 506 of the International Building Code and the formula in Section 1305.2.2.1 shall be used to determine the allowable area of the building. Enter the area value and its sign (positive or negative) in Table 1306.1 under Safety Parameter 1305.2.2, Building Area, for fire safety, means of egress and general safety. In determining the area value, the maximum permitted positive value for area is 50 percent of the fire safety score as listed in Table 1306.2, Mandatory Safety Scores. Group I-2 occupancies shall be scored zero.

1305.2.2.1 Allowable area formula. The following formula shall be used in computing allowable area:

Equation 13-3 A a = A t + ( NS × I f )

where:

A a n= Allowable building area per story (square feet). A t = Tabular allowable area factor (NS, S1, S13R, or SM value, as applicable) in accordance with Table 506.2 of the Inter- national Building Code .

NS = Tabular allowable area factor in accordance with Table 506.2 of the International Building Code for a nonsprinklered building (regardless of whether the building is sprinklered).

I f = Area factor increase due to frontage as calculated in accordance with Section 506.3 of the International Building Code .

1305.2.2.2 Area formula. The following formulas shall be used in computing the area value. Equation 13-4 shall be used for a single occupancy buildings and Equation 13-5 shall be used for multiple occupancy buildings. Determine the area value for each occupancy floor area on a floor-by-floor basis. For multiple occupancy, buildings with the minimum area value of the set of values obtained for the particular occupancy shall be used as the area value for that occupancy.

For single occupancy buildings: Equation 13-4 Area value i = (Allowable area − Actual area)/1200 square feet

For multiple occupancy buildings:
