| 2022-01-12 16:07:54 | THE FLORIDA BUILDING CODE MECHANICAL SECTION 403.3.1.1 |
| | AND TABLE 403.3.1.1 DICTATES THAT WE USE THE |
| | VENTILATION TABLE TO CALCULATE THE OUTDOOR AIR REQUIRED |
| | FOR THE USE OF SPACE IN ALL BUILDINGS. THE TABLE HAS A |
| | PARTICULAR MINIMUM OCCUPANT DENSITY THAT WE USE TO |
| | CALCULATE THE OCCUPANTS FOR EACH SPACE. WE DO NOT USE |
| | THE ARCHITECTURAL OCCUPANT COUNT TO SIZE THE MECHANICAL |
| | SYSTEMS UNLESS THE ARCHITECT?S OCCUPANT COUNT IS HIGHER |
| | THAN THE MINIMUM REQUIRED BY TABLE 403.3.1.1 IN THE |
| | MECHANICAL CODE BOOK. UPON REVIEWING THE OUTDOOR AIR |
| | CALCULATIONS FOR THIS PROJECT I SEE THAT THE CONFERENCE |
| | ROOMS AND THE LOBBY IN THE 1900 AND IN 2000 HAVE NOT |
| | BEEN SIZED USING THE TABLE 403.3.1.1 FOR THE OUTDOOR |
| | AIR CALCULATIONS. THE OUTDOOR AIR NUMBERS ARE LOW |
| | COMPARED TO WHAT WOULD BE REQUIRED. ONE EXAMPLE IS |
| | ROOMS ?1901/1931/1934 TRAINING? IT IS LISTED AS |
| | CONFERENCE/MEETING WITH A TOTAL SQUARE FOOTAGE AS 2,351 |
| | WITH TOTAL OUTDOOR AIR REQUIRED AS 401.06 CFM?S. THE |
| | CALCULATION IS ? 2351/1000 = 2.351; 2.351 X 50 = 117.55 |
| | OR 118 OCCUPANTS; 118 X 5CFM = 590CFM; 2351 X .06 = |
| | 141.06CFM; 590 + 141.06 = 731.06 OR 731 CFM?S OF |
| | OUTDOOR AIR REQUIRED FOR THIS SPACE. PLEASE CORRECT THE |
| | AREAS THAT WERE NOT CALCULATED USING THE TABLE |
| | 403.3.1.1 AND RESUBMIT THE OUTDOOR AIR CALCULATIONS. |
