| | PERMIT #15120897 |
| | BUILDING-5, TYPE III |
| | 4/7/16 |
| | |
| | 1) THERE ARE MANY INCONISTENCIES PERTAINING TO SYSTEM |
| | SIZINGS AND LOCATIONS BETWEEN THE HEAT LOAD AND ENERGY |
| | CALCULATIONS, AND THE AC PLANS AND SCHEDULES FOR THE |
| | UNITS- SHEETS M4.01, 4.02, & 4.03. FOR EXAMPLE: A) |
| | SYSTEMS A1 & A1.R ARE INDICATED AS 16,700 BTUH IN THE |
| | ENERGY CALCULATIONS BUT LISTED AS BOTH 16,700 & 21,200 |
| | IN THE SCHEDULES, AND THE HEAT LOAD CALCS INDICATE IT |
| | TO BE 16,700, 21,200 AND 26,300 DEPENDING ON THE FLOOR |
| | IT IS LOCATED ON. B) SYSTEMS B1 & B1.R ARE INDICATED TO |
| | BE 16,700 BTUH IN THE HEAT LOAD CALCS FOR TWO OF THE |
| | UNIT LOCATIONS AND 21200 FOR THE THIRD, HOWEVER THE |
| | SCHEDULE INDICATES AN ADDITIONAL B SYSTEM AT 26,300, |
| | AND NO DATA IS SHOWN FOR THE 26,300 B SYSTEM IN THE |
| | ENERGY CALCS. C) HEAT LOAD CALCULATION D, F, & J DO NOT |
| | MATCH THE DATA IN SCHEDULES OR ENERGY CALCULATIONS. D) |
| | CALCULATION P, Q, & R THAT ARE SHOWN IN THE HEAT LOAD |
| | DIAGRAMS FOR THE 4TH FLOOR ARE NOT LISTED IN THE |
| | ALPHABETICAL HEAT LOAD SCHEDULE. E) THE AC SCHEDULE ON |
| | SHEET M4.03 SHOWS A 31,000 BTUH SYSTEM FOR AHU-C3 WHICH |
| | IS NOT SHOWN IN ANY OF THE CALCULATIONS. BECAUSE OF |
| | THESE AND OTHER INCONSISTENCIES A FULL REVIEW OF SYSTEM |
| | SIZING AND ENERGY COMPLIANCE CANNOT BE COMPLETED AT |
| | THIS TIME. PLEASE REVIEW AND REVISE THE DOCUMENTS AND |
| | PLANS SO THAT THEY MATCH AND ARE INCONSISTENT. |
| | 2) THE WINDOW GLASS SQUARE FOOTAGE CALCULATIONS ON THE |
| | HEAT LOAD CALCULATIONS SHOW A MUCH LARGER AMOUNT OF |
| | GLASS COMPARED TO THE GLASS AREA CALCULATIONS ON THE |
| | UNIT FLOOR PLANS SHOWN ON SHEETS M4.01, M4.02, AND |
| | M4.03. PLEASE CLARIFY WHY NO VENTILATION AIR IS SHOWN |
| | ON THE CALCULATIONS, AND WHY NO LATENT LOADS HAVE BEEN |
| | CALCULATED FOR INFILTRATION, LIGHTING, AND EQUIPMENT? |
| | 3) THE GARAGE VENTILATION CALCULATIONS ON SHEET M5.01 |
| | INDICATE "NATURAL VENTILATION", HOWEVER THE 100 CFM PER |
| | CAR IS A MECHANICAL VENTILATION REQUIREMENT INDICATED |
| | INTABLE 403.3. PLEASE NOTE THAT NATURAL VENTILATION IS |
| | FOR OCCUPIED SPACES AS INDICATED IN SECTION 401.2, |
| | HOWEVER PER SECTION 202 DEFINITIONS, A GARAGE IS NOT |
| | CONSIDERED OCCUPIABLE SPACE. PROVIDE MECHANICAL |
| | VENTILATION PER TABLE 403.3. |
| | 4) M5.01: THE TRASH ROOM EXHAUST IS NOT CONSIDERED |
| | ENVIRONMENTAL AIR AND THEREFORE THE OUTLET SHALL BE 10' |
| | FROM OPERABLE OPENINGS INTO THE BUILDING, AND 10' ABOVE |
| | THE ADJOINING GRADE. PLEASE REVISE THE NOTE ON THE |
| | PLAN. |
| | 5) COMMENT #14 FROM THE 1ST REVIEW REQUESTING SITE |
| | SPECIFIC WIND LOAD ENGINEERING FOR THE ROOF TOP STANDS |
| | AND CONDENSERS STILL EXISTS: PLEASE COMPLY. |
| | 6) PLEASE SHOW THE DRYER RUN LENGTHS ON THE PLANS AND |
| | NUMBER OF ELBOWS TO BE USED TO VERIFY COMPLIANCE WITH |
| | THE DRYER SPECS ON SHEET M5.02. |
