The Standard Baseline Model:

The Standard Baseline Model: 1. Total kitchen exhaust shall be either: a) If the total exhaust is less than 5,000 cfm, the user entered total exhaust rate. b) If the total exhaust rate is greater than or equal to 5,000 cfm, a total exhaust rate that is the sum of the Type I hoods based on the user input data and less than or equal to the maximum net exhaust flow rate in Table 144-C. c) Hood exhaust total static pressure shall be 2.5” and the fan efficiency shall be 50%. 2. Conditioning Systems a. The Cooling Load and Cooling CFM for the kitchen are calculated using a Cooling Space Setpoint of 80°F and a Cooling Supply Air temperature setpoint of 60°F.     b. The standard model shall use a 100% outside air direct evaporative system if the space temperature exceeds 80oF less than 10 hour per year, i.e. the compliance software will have to first run direct evaporative and then run DX if direct evaporative cannot meet the comfort criteria. i. Direct evaporative system assumptions: 1. 90% direct evaporative effectiveness 2. 1.5” total fan static, 60% fan efficiency 3. 100% outside airflow equal to the total kitchen exhaust c. If the standard model cannot meet the direct evaporative criteria, the system shall be modeled as System 1 or 2 except as noted herein: i. The standard model shall model the makeup air unit as a 100% outside air packaged unit ii. Supply cfm shall use the larger of the Cooling CFM or the Total Exhaust minus the Available Transfer. iii. Total fan static for the packaged unit shall be 2.0” , fan efficiency shall be 50
