CODE REVIEW6

Existing building code review: 1982 Southern Building Code and 1981 NFPA 101 Lab building classified as B business and Type II construction First floor sprinklered. First floor area 19,948 gross, 16,509 net Second floor area 18,100 gross, 14,922 net Existing stairs are 4'-6” wide. Current Code 2015 IBC and 2015 NFPA 101 Occupant load at Concrete Lab = 1780 sf gross, 1178 sf net at 50 sf net/occ = 24 occupants Ocupant load at Classroom = 1172 sf at 30sf/occ = 40 occupants

(half to north and half to south = 20 each direction) Total load in Concrete Lab = 24 plus 20 = 44 occupants = 1 exit required. Second floor load: 4 Labs = 3469 sf at 30 sf/occ = 116 occupants

(half exit down the exterior stairs = 58) Study Lounge = 1058 sf at 30 sf/occ = 36 Total load at Second Floor = 36 + 58 = 94 occupants exiting down exterior stairs. 0.3” width per occupant = 28.2” of stair width required.

WHEN DUST COLLECTOR IS NOT ACTIVE, EACH TERMINAL UNIT SHALL MODULATE THE SUPPLY AIR DAMPER TOMAINTAIN THE SPACE TEMPERATURE CONDITIONS. IF THE ZONE REQUIRES COOLING, THE SUPPLY AIR DAMPERSHALL BE MODULATED BETWEEN THE MINIMUM AND MAXIMUM COOLING AIR FLOWS TO MAINTAIN THE SPACETEMPERATURE AT THE COOLING SETPOINT OF 73°F (ADJUSTABLE). IF THE ZONE CALLS FOR HEATING, THE SUPPLYAIR DAMPER SHALL BE MODULATED TO A MINIMUM AND THE HW VALVE SHALL BE MODULATED TO MAINTAIN THESPACE TEMPERATURE AT THE HEATING SETPOINT OF 72°F (ADJUSTABLE). IF ADDITIONAL HEATING IS REQUIREDWHEN THE VALVE IS FULLY OPEN, THE SUPPLY AIR DAMPER SHALL BE MODULATED TO MEET THE ROOMTEMPERATURE REQUIREMENTS. VAV BOX SHALL BE CONNECTED TO ZONE THERMOSTAT.
