| | PLAN REVIEW RESULTS: DENIED. |
| | |
| | 1) THE MECHANICAL EQUIPMENT SIZING CALCULATIONS |
| | SUBMITTED THIS CYCLE INDICATE AN AREA OF 2400 SQ. FT. |
| | IS TO BE CONDITIONED. IT IS NOT CLEAR IF THIS IS THE |
| | SALES, KITCHEN AREA, OFFICE SPACE AND STORAGE OR JUST A |
| | PORTION OF THIS TENANT SPACE. THE TOTAL SIZE OF THE |
| | SYSTEM IS TO BE 9.30 TONS. THE NEWLY SUBMITTED SHEET |
| | M6.1 SHOWS THE EXISTING RTU IS 124,100 BTU???S THIS |
| | DIVIDED BY 12000 = 10.34 TONS. THE NEWLY SUBMITTED FC-1 |
| | HAS A TOTAL BTU LOAD OF 24000 BTU???S, THIS DIVIDED BY |
| | 12000 = 2 TONS. THIS MEANS THE TOTAL OF ALL SYSTEMS IS |
| | 12.34 TONS. THE MECHANICAL EQUIPMENT SIZING |
| | CALCULATIONS CALLS FOR 9.30 TONS. THIS MEANS THE |
| | MECHANICAL SYSTEM IS OVER SIZED BY 3.04 TONS. IT IS |
| | UNCLEAR TO THIS REVIEWER WITH THE DRAWINGS SUBMITTED IF |
| | THE ENERGY CALCULATIONS IS ONLY FOR THE FRONT OF THE |
| | TENANT SPACE OR FOR THE ENTIRE SPACE. THE OUTSIDE AIR |
| | CALCULATIONS SEEM TO BE FOR THE ENTIRE TENANT SPACE. IF |
| | THIS IS FOR THE ENTIRE TENANT SPACE THEN THE MECHANICAL |
| | DESIGN IS TOO LARGE FOR THE TENANT SPACE AND THE |
| | DESIGNER MUST COMPLY WITH FEC C403.2.2. THE RESPONSE |
| | LETTER INDICATED THAT THE SYSTEM WAS UPSIZED BECAUSE OF |
| | HUMIDITY AND IT BEING FLORIDA. IF THE UNITS ARE OVER |
| | SIZED THEN IN FACT THE UNITS WOULD SHORT CYCLE WHICH |
| | MEANS THEY WOULD SHUT OFF ONCE THE THERMOSTAT |
| | TEMPERATURE HAS BEEN MET. THIS WOULD HAPPEN QUICKER |
| | THAN IF THE SYSTEM WAS SIDED CORRECTLY. THIS IN TURN |
| | WOULD MEAN THE SYSTEMS WOULD SHUT OFF BEFORE THE |
| | HUMIDITY HAD BEEN REMOVED FROM THE BUILDING. THE |
| | SYSTEMS MUST MEET THE REQUIREMENTS OF FEC C403.2.2. |
| | PLEASE PROVIDE THE SQUARE FOOTAGE THAT EACH MECHANICAL |
| | SYSTEM IS SUPPLYING AND SIZE EACH UNIT ACCORDING TO FEC |
| | C403.2.1 AND C403.2.2 |
| | |
| | C403.2.2 EQUIPMENT SIZING. THE OUTPUT CAPACITY OF |
| | HEATING AND COOLING EQUIPMENT SHALL BE NOT GREATER THAN |
| | THE |
| | LOADS CALCULATED IN ACCORDANCE WITH SECTION C403.2.1. A |
| | SINGLE PIECE OF EQUIPMENT PROVIDING BOTH HEATING AND |
| | COOLING SHALL SATISFY THIS PROVISION FOR ONE FUNCTION |
| | WITH THE CAPACITY FOR THE OTHER FUNCTION AS SMALL AS |
| | POSSIBLE, WITHIN AVAILABLE EQUIPMENT OPTIONS. |
| | |
| | 2) WITH THE NEWLY ADDED FC-1 ADDED FOR THE STORAGE AND |
| | OFFICE PLEASE SHOW HOW THE REQUIRED OUTSIDE AIR WILL BE |
| | INTRODUCED TO THE RETURN SIDE OF THE FC-1 SYSTEM. FMC |
| | 403.3.1.1 |
| | |
| | 3) THE CONDENSING UNIT FOR FC-1 LOCATED ON THE ROOF |
| | WILL NEED TO MEET THE ROOF EDGE CLEARANCES OR INSTALL |
| | GUARDS PER FMC 304.11 |
| | |
| | WHEN RESUBMITTING, IT IS HELPFUL TO PROVIDE A RESPONSE |
| | LETTER ADDRESSING EACH ITEM. |
