Section 503.2.4.4 of the Florida Energy Code indicates the following: Shutoff damper controls. Both outdoor air supply and exhaust ducts shall be equipped with dampers that will automatically shut when the systems or spaces served are not in use. In order to meet the intent of the code section indicated above, BMC Consulting, would seek to meet the intent of the code (identified above) by incorporating a "Back Draft Damper" (BDD) within the outside air intake duct in lieu of a motorized damper. The BDD would close automatically via gravity when the HVAC system is shut down. Any questions, please feel free to contact BMC Consulting, LLC at 1-561-644- 1329 Sincerely, BRUCE M CIARLARIELLO, P.E., CMR, LEED AP, CXA PRESIDENT BMC CONSULTING, LLC �14 0 pC>,c.'••...c OR10,,.• BMC Consulting, LLC (CA-29409) 8297 Rosalie Ln, Wellington, FL 33414 — Phone:1-561-644-1329 — Fax: 1-561-296-5260 E-mail: bruce@bmcconsultinellc.com website: www.bmcconsultinglic.com Air System Sizing Summary for AHU-1 I Project Name: NATIONAL NAVY UDT-SEAL MUSEUM 10/15/2014 Prepared by: BMC Consulting, LLC 09:16PM Air System Information Air System Name Equipment Class Air System Type _AHU-1 SPLT AHU _ SZCAV Sizing Calculation Information Zone and Space Sizing Method: Zone CFM Sum of space airflow rates Space CFM Individual peak space loads Central Cooling Coil Sizing Data Total coil load 0.8 Total coil load 10.1 Sensible coil load 9.6 Coil CFM at Jun 0900 447 Max block CFM 447 Sum of peak zone CFM 447 Sensible heat ratio 0.954 ftz/fon 169.7 BTU/(hr-ftz) _ 70.7 Water flow @ 10.0 •F rise N/A Number of zones 1 Floor Area 143.0 ftz Location West Palm Beach, Florida Calculation Months Jan to Dec Sizing Data Calculated Tons Load occurs at Jun 0900 MBH OA DB / WB 80.7 / 75.6 °F MBH Entering DB / WB 76.1 / 62.7 •F CFM Leaving DB / WB 56.2 / 54.9 •F CFM Coil ADP 53.9 •F CFM Bypass Factor 0.100 Resulting RH 46 % Design supply temp. 55.0 °F Zone T-stat Check 1 of 1 OK Max zone temperature deviation 0.0 •F Central Heating Coil Sizing Data Max coil load 3.6 MBH Coil CFM at Des Htg 447 CFM Max coil CFM 447 CFM Water flow @ 20.0 °F drop N/A Supply Fan Sizing Data Actual max CFM Standard CFM Actual max CFM/ftz Outdoor Ventilation Air Data Design airflow CFM CFM/ftz .447 CFM .447 CFM 3.13 CFM/ftz -11 CFM 0.08 CFM/ftz Load occurs at BTU/(hr-ftz) _ Ent.
