| | TO SECTION C403.2.1 FBC-14 ENERGY CONSERVATION AND |
| | PROVIDE COOLING AND HEATING LOAD CALCULATIONS: |
| | CALCULATION OF HEATING AND COOLING LOADS. |
| | DESIGN LOADS SHALL BE DETERMINED IN ACCORDANCE WITH THE |
| | PROCEDURES DESCRIBED IN THE ASHRAE/ACCA STANDARD 183 OR |
| | ACCA MANUAL N AND SHALL BE ATTACHED TO THE CODE |
| | COMPLIANCE FORM SUBMITTED TO THE BUILDING DEPARTMENT |
| | WHEN THE BUILDING IS PERMITTED OR, IN THE EVENT THE |
| | MECHANICAL PERMIT IS OBTAINED AT A LATER TIME, THE |

| | M1.0 IN ACCORDANCE WITH THE SCHEDULES SHOWN ON SHEET |
| | M1.1. |
| | 6) A2.0, S5.1, & M1.2: REFER TO SECTION 301.15 FBC-14 |
| | MECHANICAL AND PROVIDE WIND LOAD TIE DOWN ENGINEERING |
| | FOR THE ROOFTOP EQUIPMENT AND COMPONENTS. INDICATE ON |
| | THE PLANS THE WIND LOAD DESIGN CRITERIA, DESIGN |
| | PRESSURES, AND DETAILS FOR ATTACHMENT OF THE RTU AND |
| | FAN CURBS TO THE ROOF STRUCTURE, AND RTU'S AND FANS TO |
| | THE CURBS. |
| | 7) S5.1: PROVIDE STRUCTURAL DETAILS FOR COVERING THE |
| | ROOF OPENINGS OF THE REMOVED RTU'S (WHERE APPLICABLE). |
| | 8) PROVIDE A CONDENSATE DISPOSAL PLAN- INDICATE THE |
| | TYPE AND SIZE OF RTU CONDENSATE PIPES, SHOW THE PIPE |
| | RUNS, SHOW HOW THE PIPE WILL BE SUPPORTED AND PROTECTED |
| | FROM UV DEGRADATION, AND INDICATE THE DISCHARGE |
| | LOCATIONS- REFER TO SECTION 307 FBC-14 MECHANICAL. |
| | 9) M1.1: IN REGARD TO THE NEW AC SYSTEMS AND |
| | ECONOMIZERS PLEASE SHOW COMPLIANCE WITH THE FOLLOWING |
| | SECTIONS OF THE FBC-14 ENERGY CONSERVATION: |
| | A) C403.2.5.1 DEMAND CONTROLLED VENTILATION. |
| | DEMAND CONTROL VENTILATION (DCV) SHALL BE PROVIDED FOR |
| | SPACES LARGER THAN 500 SQUARE FEET (50 M2) AND WITH AN |
| | AVERAGE OCCUPANT LOAD OF 25 PEOPLE PER 1000 SQUARE FEET |
| | (93 M2) OF FLOOR AREA (AS ESTABLISHED IN TABLE 403.3 OF |
| | THE FLORIDA BUILDING CODE, MECHANICAL) AND SERVED BY |
| | SYSTEMS WITH ONE OR MORE OF THE FOLLOWING: |
| | 1. AN AIR-SIDE ECONOMIZER; |
| | 2. AUTOMATIC MODULATING CONTROL OF THE OUTDOOR AIR |
| | DAMPER; OR |
| | 3. A DESIGN OUTDOOR AIRFLOW GREATER THAN 3,000 CFM |
| | (1400 L/S). |
| | EXCEPTION: DEMAND CONTROL VENTILATION IS NOT REQUIRED |
| | FOR SYSTEMS AND SPACES AS FOLLOWS: |
| | 1. SYSTEMS WITH ENERGY RECOVERY COMPLYING WITH SECTION |
| | C403.2.6. |
| | 2. MULTIPLE-ZONE SYSTEMS WITHOUT DIRECT DIGITAL CONTROL |
| | OF INDIVIDUAL ZONES COMMUNICATING WITH A CENTRAL |
| | CONTROL PANEL. |
| | 3. SYSTEM WITH A DESIGN OUTDOOR AIRFLOW LESS THAN 1,200 |
| | CFM (600 L/S). |
| | 4. SPACES WHERE THE SUPPLY AIRFLOW RATE MINUS ANY |
| | MAKEUP OR OUTGOING TRANSFER AIR REQUIREMENT IS LESS |
| | THAN 1,200 CFM (600 L/S). |
| | 5. VENTILATION PROVIDED FOR PROCESS LOADS ONLY. |
| | B) C403.3.1.1 AIR ECONOMIZERS. |
| | AIR ECONOMIZERS SHALL COMPLY WITH SECTIONS C403.3.1.1.1 |

| | CONTROL TYPES FOR SPECIFIC CLIMATES SHALL BE CHOSEN |
| | FROM TABLE C403.3.1.1.3(1). HIGH-LIMIT SHUTOFF CONTROL |

| | MECHANICAL OR PLUMBING SYSTEMS APPEARS TO BE |
| | UNDERESTIMATED ON THE APPLICATION, THE PERMIT SHALL BE |
| | DENIED, UNLESS THE APPLICANT CAN SHOW |
| | DETAILED, QUANTITY ESTIMATES, AND/OR BONA FIDE SIGNED |
