| | 333 FERN ST. |
| | |
| | PLEASE REFER TO THE 1ST REVIEW COMMENTS AND THE |
| | SUBMITTED NARRATIVE RESPONSE. |
| | |
| | 1) COMMENT #1 FROM THE 1ST REVIEW, REQUEST FOR AC |
| | CALCULATIONS: THE CALCULATIONS HAVE BEEN SUBMITTED |
| | HOWEVER, PLEASE REVIEW UPLOADED FILE TITLED "ISIS |
| | COMMON AREAS" I AM FINDING SOME OF THE SYSTEM TITLES ON |
| | THE CALCS DO NOT MATCH THE SYSTEM TITLES ON THE |
| | SCHEDULES I.E. AC 2-2 IS TITLED "ELEVATOR SERVICE" IN |
| | THE CALCS BUT LISTED AS 2ND LEVEL VESTIBULE IN THE |
| | SCHEDULE, AC-2-5 IN THE CALCS BUT NOT IN THE SCHEDULES. |
| | IN ADDITION, I AM NOT FINDING CALCULATIONS FOR RTU-1, |
| | AND PACU-1 & 2, AND ALL OF THE MITSUBISHI GROUND FLOOR |
| | SYSTEMS HAVE OVERSIZED HEATING CAPACITIES PER THE |
| | CALCS- REFER TO SECTION 503.2.2 FBC-10 ENERGY |
| | CONSERVATION. |
| | 2) COMMENT #2 FROM THE 1ST REVIEW, REQUEST FOR ENERGY |
| | CALCS: ENERGY EFFICIENCY FORM 506-2010 HAS BEEN |
| | SUBMITTED, HOWEVER THERE ARE A FEW ISSUES CORRELATING |
| | THE CALCS WITH THE AC SYSTEMS: A) REFER TO SHEET M4.00 |
| | "SPLIT AC UNIT SCHEDULE"- CU'S 4A & 5A ARE NOT IN THE |
| | CALCS. B) M4.00 "DUCTLESS SPLIT SYSTEM COMMON AREAS"- |
| | THE SCHEDULE INDICATES 2.0 TON/20.7 SEER SYSTEMS FOR |
| | RETAIL, HOWEVER THE CALCS INDICATE RETAIL A (40,800 |
| | BTU'S/19 SEER) & RETAIL B (19,000 BTU'S/20 SEER). C) |
| | M.400 "DUCTLESS SPLIT SYSTEM COMMON AREAS"- THE COOLING |
| | AND HEATING CAPACITIES AND SEERS IN THE SCHEDULE DON'T |
| | MATCH WITH THE CALCS. D) M4.01 "SPLIT AIR CONDITIONING |
| | UNIT SCHEDULE"- THE COOLING AND HEATING CAPACITIES, THE |
| | TAG #S, THE SEERS, AND THE LOCATIONS OF THE SYSTEMS AS |
| | SHOWN IN THE SCHEDULE DO NOT MATCH THE CALCS. PLEASE |
| | REVIEW AND REVISE ACCORDINGLY, AND COMPLETE THE |
| | COMPLIANCE CHECKLIST ON PAGE 31- PLACE A CHECK MARK IN |
| | EACH APPLICABLE BOX. |
| | 3) COMMENT #4 FROM THE 1ST REVIEW: MANUFACTURER'S |
