| | 7/29/15 |
| | |
| | 1) SHEETS M1.0 , M1.1, M1.2, & M1.3: PROVIDE PRIMARY |
| | AND AUXILIARY CONDENSATE DISPOSAL PLANS FOR THE NEW AIR |
| | HANDLERS. REVISE THE DRAWINGS ACCORDINGLY. |
| | 2) M1.0, M1.1, M1.2, & M1.3: DUCT SMOKE DETECTORS ARE |
| | REQUIRED IN THE AHU RETURN DUCTS- SECTION 606.2.1 |
| | FBC-10 MECHANICAL. REVISE THE DRAWINGS ACCORDINGLY. |
| | 3) M1.0, M1.1, M1.2, & M1.3: CORRECT THE AHU NUMBERS IN |
| | KEYNOTE #2 SO THEY MATCH WITH THE AHU NUMBERS SHOWN IN |
| | THE DIAGRAMS. |
| | 4) M2.1: THE TOTAL O/A SHOWN IN THE SCHEDULES FOR EACH |
| | PAIRING OF AHU'S IS EXCEEDING THE AMOUNT OF O/A BEING |
| | SUPPLIED BY THE DEDICATED OAU FOR THOSE TWO SYSTEMS: |
| | PLEASE CLARIFY. |
| | 5) PLEASE REVIEW AND SHOW COMPLIANCE WITH SECTION C408 |
| | SYSTEM COMMISSIONING , FBC-14 ENERGY CONSERVATION: |
| | |
| | C408.1 GENERAL. |
| | THIS SECTION COVERS THE COMMISSIONING OF THE BUILDING |
| | MECHANICAL SYSTEMS IN SECTION C403 AND ELECTRICAL POWER |
| | AND LIGHTING SYSTEMS IN SECTION C405. |
| | |
| | C408.2 MECHANICAL SYSTEMS COMMISSIONING AND COMPLETION |
| | REQUIREMENTS. |
| | PRIOR TO PASSING THE FINAL MECHANICAL INSPECTION, THE |
| | REGISTERED DESIGN PROFESSIONAL SHALL PROVIDE EVIDENCE |
| | OF MECHANICAL SYSTEMS COMMISSIONING AND COMPLETION IN |
| | ACCORDANCE THE PROVISIONS OF THIS SECTION. |
| | |
| | CONSTRUCTION DOCUMENT NOTES SHALL CLEARLY INDICATE |
| | PROVISIONS FOR COMMISSIONING AND COMPLETION |
| | REQUIREMENTS IN ACCORDANCE WITH THIS SECTION AND ARE |
| | PERMITTED TO REFER TO SPECIFICATIONS FOR FURTHER |
| | REQUIREMENTS. COPIES OF ALL DOCUMENTATION SHALL BE |
| | GIVEN TO THE OWNER AND MADE AVAILABLE TO THE CODE |
| | OFFICIAL UPON REQUEST IN ACCORDANCE WITH SECTIONS |
| | C408.2.4 AND C408.2.5. |
| | |
| | EXCEPTION: THE FOLLOWING SYSTEMS ARE EXEMPT FROM THE |
| | COMMISSIONING REQUIREMENTS: |
| | |
| | 1. MECHANICAL SYSTEMS IN BUILDINGS WHERE THE TOTAL |
| | MECHANICAL EQUIPMENT CAPACITY IS LESS THAN 480,000 |
| | BTU/H (140 690 W) COOLING CAPACITY AND 600,000 BTU/H |
| | (175 860 W) HEATING CAPACITY. |
| | |
| | 2. SYSTEMS INCLUDED IN SECTION C403.3 THAT SERVE |
| | DWELLING UNITS AND SLEEPING UNITS IN HOTELS, MOTELS, |
| | BOARDING HOUSES OR SIMILAR UNITS. |
| | |
| | C408.2.1 COMMISSIONING PLAN. |
| | A COMMISSIONING PLAN SHALL BE DEVELOPED BY A REGISTERED |
| | DESIGN PROFESSIONAL OR APPROVED AGENCY AND SHALL |
| | INCLUDE THE FOLLOWING ITEMS: |
| | |
| | 1. A NARRATIVE DESCRIPTION OF THE ACTIVITIES THAT WILL |
| | BE ACCOMPLISHED DURING EACH PHASE OF COMMISSIONING, |
| | INCLUDING THE PERSONNEL INTENDED TO ACCOMPLISH EACH OF |
| | THE ACTIVITIES. |
| | |
| | 2. A LISTING OF THE SPECIFIC EQUIPMENT, APPLIANCES OR |
| | SYSTEMS TO BE TESTED AND A DESCRIPTION OF THE TESTS TO |
| | BE PERFORMED. |
| | |
| | 3. FUNCTIONS TO BE TESTED, INCLUDING, BUT NOT LIMITED |
| | TO CALIBRATIONS AND ECONOMIZER CONTROLS. |
| | |
| | 4. CONDITIONS UNDER WHICH THE TEST WILL BE PERFORMED. |
| | AT A MINIMUM, TESTING SHALL AFFIRM WINTER AND SUMMER |
| | DESIGN CONDITIONS AND FULL OUTSIDE AIR CONDITIONS. |
| | |
| | 5. MEASURABLE CRITERIA FOR PERFORMANCE. |
| | |
| | C408.2.2 AIR DISTRIBUTION SYSTEM TESTING, ADJUSTING AND |
| | BALANCING. |
| | CONSTRUCTION DOCUMENTS SHALL REQUIRE THAT A WRITTEN |
| | BALANCE REPORT BE PROVIDED TO THE OWNER OR THE |
| | DESIGNATED REPRESENTATIVE OF THE BUILDING OWNER FOR |
| | HVAC SYSTEMS SERVING ZONES WITH A TOTAL CONDITIONED |
| | AREA EXCEEDING 5000 SQUARE FEET (465 M2). AIR |
| | DISTRIBUTION SYSTEMS SHALL BE TESTED, ADJUSTED, AND |
| | BALANCED BY A LICENSED ENGINEER OR A COMPANY OR |
| | INDIVIDUAL HOLDING A CURRENT CERTIFICATION FROM A |
| | RECOGNIZED TESTING AND BALANCING AGENCY ORGANIZATION IN |
| | ACCORDANCE WITH GENERALLY ACCEPTED ENGINEERING |
| | STANDARDS. |
| | |
| | EXCEPTIONS: |
| | |
| | 1. BUILDINGS WITH COOLING OR HEATING SYSTEM CAPACITIES |
| | OF 15 TONS OR LESS PER SYSTEM MAY BE TESTED AND |
| | BALANCED BY A MECHANICAL CONTRACTOR LICENSED TO DESIGN |
| | AND INSTALL SUCH SYSTEM(S). |
| | |
| | 2. BUILDINGS WITH COOLING OR HEATING SYSTEM CAPACITIES |
| | OF 65,000 BTU/H OR LESS PER SYSTEM ARE EXEMPT FROM THE |
| | REQUIREMENTS OF THIS SECTION. |
| | |
| | C408.2.2.1 AIR SYSTEM BALANCING. |
| | AIR SYSTEM BALANCING SHALL BE ACCOMPLISHED IN A MANNER |
| | TO FIRST MINIMIZE THROTTLING LOSSES, THEN FOR FANS WITH |
| | FAN SYSTEM POWER GREATER THAN 1 HP, FAN SPEEDS SHALL BE |
| | ADJUSTED TO MEET DESIGN FLOW CONDITIONS. BALANCING |
| | PROCEDURES SHALL BE IN ACCORDANCE WITH THE NATIONAL |
| | ENVIRONMENTAL BALANCING BUREAU (NEBB) PROCEDURAL |
| | STANDARDS, THE ASSOCIATED AIR BALANCE COUNCIL (AABC) |
| | NATIONAL STANDARDS, OR EQUIVALENT PROCEDURES. |
| | |
| | EXCEPTION: DAMPER THROTTLING MAY BE USED FOR AIR SYSTEM |
| | BALANCING WITH FAN MOTORS OF 1 HP OR LESS, OR IF |
| | THROTTLING RESULTS IN NO GREATER THAN 1/3 HP FAN |
| | HORSEPOWER DRAW ABOVE THAT REQUIRED IF THE FAN SPEED |
| | WERE ADJUSTED. |
| | |
| | NOTES: |
| | |
| | 1. BUILDING ENVELOPE PRESSURIZATION SHOULD BE EITHER |
| | NEUTRAL OR POSITIVE TO PREVENT INFILTRATION OF EXCESS |
| | LATENT LOAD. |
| | |
| | 2. COMMERCIAL KITCHEN HOOD EXHAUST CFM SHOULD BE SIZED |
| | TO PREVENT DEPRESSURIZATION. DISCHARGE DAMPERS ARE |
| | PROHIBITED ON CONSTANT VOLUME FANS AND VARIABLE VOLUME |
| | FANS WITH MOTORS 10 HORSEPOWER (HP) (7.5 KW) AND |
| | LARGER. |
