| | PERMIT #15071043 |
| | |
| | 1) DESIGN CRITERIA: PROVIDE ON THE PLAN A LIST OF |
| | CURRENT CODES AND STANDARDS USED FOR DESIGN AND |
| | INSTALLATION OF THE PROPOSED HVAC SYSTEM(S) |
| | ALTERATIONS. |
| | 2) PROVIDE A NARRATIVE TO CLARIFY THE SCOPE AND EXTENT |
| | OF THE PROJECT PROJECT TO BE COVERED UNDER THIS PERMIT |
| | APPLICATION. BASED ON THE THE PHASING DIAGRAMS ON SHEET |
| | AE002 IT APPEARS THAT THE SUBMITTED PLANS WILL LIMIT |
| | THE PROJECT TO THE NORTH SIDE ALTERATIONS CULMINATING |
| | AT STAGE 2, AND WILL NOT INCLUDE THE EXPANSION ON THE |
| | WEST AND SOUTH SIDES. |
| | 3) REFERENCE THE FBC-14 EXISTING BUILDING CODE, SECTION |
| | 809.2 ALTERED EXISTING SYSTEMS: IN MECHANICALLY |
| | VENTILATED SPACES, EXISTING MECHANICAL VENTILATION |
| | SYSTEMS THAT ARE ALTERED, RECONFIGURED, OR EXTENDED |
| | SHALL PROVIDE NOT LESS THAN 5 CUBIC FEET PER MINUTE |
| | (CFM) (0.0024 M3/S) PER PERSON OF OUTDOOR AIR AND NOT |
| | LESS THAN 15 CFM (0.0071 M3/S) OF VENTILATION AIR PER |
| | PERSON; OR NOT LESS THAN THE AMOUNT OF VENTILATION AIR |
| | DETERMINED BY THE INDOOR AIR QUALITY PROCEDURE OF |
| | ASHRAE 62. PLEASE PROVIDE A VENTILATION SCHEDULE ON THE |
| | PLAN INDICATING THE REQUIRED CFM'S OF O/A PER THE |
| | REFERENCED SECTION, AND THE CFM'S OF O/A TO BE |
| | PROVIDED. SEE ALSO TABLE 403.3 FBC-14 MECHANICAL. |
| | 4) SIZING CALCULATIONS ARE REQUIRED FOR AHU'S 25, |
| | 26,27,28, & 29. REFERENCE THE FBC-14 ENERGY |
| | CONSERVATION CODE, SECTION C403.2.1 C403.2.1 |
| | 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 |
| | SIZING CALCULATION SHALL BE SUBMITTED WITH THE |
| | APPLICATION FOR THE MECHANICAL PERMIT. HEATING AND |
| | COOLING LOADS SHALL BE ADJUSTED TO ACCOUNT FOR LOAD |
| | REDUCTIONS THAT ARE ACHIEVED WHEN ENERGY RECOVERY |
| | SYSTEMS ARE UTILIZED IN THE HVAC SYSTEM IN ACCORDANCE |
| | WITH THE ASHRAE HVAC SYSTEMS AND EQUIPMENT HANDBOOK. |
| | ALTERNATIVELY, DESIGN LOADS SHALL BE DETERMINED BY AN |
| | APPROVED EQUIVALENT COMPUTATION PROCEDURE, USING THE |
| | DESIGN PARAMETERS SPECIFIED IN CHAPTER 3. |
| | 5) PROVIDE CHILLED AND HOT WATER PIPING AND VALVE |
| | SCHEDULES, AND INSTALLATION NOTES AND DETAILS. |
| | 6) REFERENCE SECTION C403.4.5 FBC-14 ENERGY |
| | CONSERVATION AND SHOW COMPLIANCE- REQUIREMENTS FOR |
| | COMPLEX MECHANICAL SYSTEMS SERVING MULTIPLE ZONES: |
| | SECTIONS C403.4.5.1 THROUGH C403.4.5.4 SHALL APPLY TO |
| | COMPLEX MECHANICAL SYSTEMS SERVING MULTIPLE ZONES. |
| | SUPPLY AIR SYSTEMS SERVING MULTIPLE ZONES SHALL BE VAV |
| | SYSTEMS WHICH, DURING PERIODS OF OCCUPANCY, ARE |
| | DESIGNED AND CAPABLE OF BEING CONTROLLED TO REDUCE |
| | PRIMARY AIR SUPPLY TO EACH ZONE TO ONE OF THE FOLLOWING |
| | BEFORE REHEATING, RECOOLING OR MIXING TAKES PLACE: |
| | 1. THIRTY PERCENT OF THE MAXIMUM SUPPLY AIR TO EACH |
| | ZONE. |
| | 2. THREE HUNDRED CFM (142 L/S) OR LESS WHERE THE |
| | MAXIMUM FLOW RATE IS LESS THAN 10 PERCENT OF THE TOTAL |
| | FAN SYSTEM SUPPLY AIRFLOW RATE. |
| | 3. THE MINIMUM VENTILATION REQUIREMENTS OF CHAPTER 4 OF |
| | THE FLORIDA BUILDING CODE, MECHANICAL. |
| | |
| | EXCEPTION: THE FOLLOWING DEFINE WHERE INDIVIDUAL ZONES |
| | OR WHERE ENTIRE AIR DISTRIBUTION SYSTEMS ARE EXEMPTED |
| | FROM THE REQUIREMENT FOR VAV CONTROL: |
| | 1. ZONES WHERE SPECIAL PRESSURIZATION RELATIONSHIPS OR |
| | CROSS-CONTAMINATION REQUIREMENTS ARE SUCH THAT VAV |
| | SYSTEMS ARE IMPRACTICAL. |
| | 2. ZONES OR SUPPLY AIR SYSTEMS WHERE AT LEAST 75 |
| | PERCENT OF THE ENERGY FOR REHEATING OR FOR PROVIDING |
| | WARM AIR IN MIXING SYSTEMS IS PROVIDED FROM A |
| | SITE-RECOVERED OR SITE-SOLAR ENERGY SOURCE. |
| | 3. ZONES WHERE SPECIAL HUMIDITY LEVELS ARE REQUIRED TO |
| | SATISFY PROCESS NEEDS. |
| | 4. ZONES WITH A PEAK SUPPLY AIR QUANTITY OF 300 CFM |
| | (142 L/S) OR LESS AND WHERE THE FLOW RATE IS LESS THAN |
| | 10 PERCENT OF THE TOTAL FAN SYSTEM SUPPLY AIRFLOW RATE. |
| | 5. ZONES WHERE THE VOLUME OF AIR TO BE REHEATED, |
| | RECOOLED OR MIXED IS NO GREATER THAN THE VOLUME OF |
| | OUTSIDE AIR REQUIRED TO MEET THE MINIMUM VENTILATION |
| | REQUIREMENTS OF CHAPTER 4 OF THE FLORIDA BUILDING CODE, |
| | MECHANICAL. |
| | 6. ZONES OR SUPPLY AIR SYSTEMS WITH THERMOSTATIC AND |
| | HUMIDISTATIC CONTROLS CAPABLE OF OPERATING IN SEQUENCE |
| | THE SUPPLY OF HEATING AND COOLING ENERGY TO THE ZONES |
| | AND WHICH ARE CAPABLE OF PREVENTING REHEATING, |
| | RECOOLING, MIXING OR SIMULTANEOUS SUPPLY OF AIR THAT |
| | HAS BEEN PREVIOUSLY COOLED, EITHER MECHANICALLY OR |
| | THROUGH THE USE OF ECONOMIZER SYSTEMS, AND AIR THAT HAS |
| | BEEN PREVIOUSLY MECHANICALLY HEATED. |
