Section B <br /> Ventilation Method <br /> (Choose either balanced or exhaust only) <br /> Balanced,HRV(Heat Recovery Ventilator)or ERV(Energy Exhaust only <br /> every Ventilator)—cfm of unit in low must not exceed continuous Continuous fan rating in cfm <br /> ventilation rating more th 00%. <br /> Low dm: High cfm: Continuous fan rating In cfm(rapacity must not exceed <br /> continuous ventilation rating more than 100% <br /> Directions-Choose the method of ventilation,balanced or exhaust only. Balanced ventilation systems are typically HRV or <br /> ERV's.Enter the low and high cfm amounts. Low cfm airflow must be equal to or greater than the required continuous <br /> ventilation rate and less than 10096 greater than the continuous rate.(For instance,If the low cfm is 40 cfm,the ventilation fan <br /> must not exceed 80 cfm.) Automatic controls may allow the use of a larger fan that is operated a percentage of each hour. <br /> Section C <br /> Ventilation Fan Schedule <br /> Description Location Continuous Intermittent <br /> Directions-The ventilation fan schedule should describe what the fan is for,the location,cfm,and whether It Is used for <br /> continuous or intermittent ventilation. The fan that Is chose for continuous ventilation must be equal to or greater than the <br /> low cfm air rating and less than 100%greater than the continuous rote. (For Instance,If the low cfm is 40 cfm,the continuous <br /> ventilation fan must not exceed 80 cfm.) Automatic controls may allow the use of a larger fan that is operated a percentage of <br /> each hour. <br /> Section D <br /> Ventilation Controls <br /> Describe operation and control of the continuous and intermittent ventilation <br /> Directions.Describe the operation of the ventilation system. There should be adequate detail for plan reviewers and Inspectors to verify <br /> design and Installation compliance. Related trades also need adequate detall for placement of controls and proper operation of the building <br /> ventilation. If exhaust fans are used for building ventilation,describe the operation and location of any controls,Indicators and legends. If <br /> an ERV or HRV Is to be installed,describe how It will be Installed.If It will be connected and interfoad with the air handling equipment, <br /> please describe such connections as detailed in the manufactures'Installation instructions.If the installation Instructions require or <br /> recommend the equipment to be Interlocked with the air handling equipment for proper operation,such Interconnection shall be made and <br /> described. <br /> Section E <br /> Make-up air <br /> Passive (determined from calculations from Table 501.3.1) <br /> Powered(determined from calculations from Table 501.3.1) <br /> Interlocked with exhaust device(determined from calculation from Table 501.3.1) <br /> Other,describe: <br /> Location of duct or system ventilation make-up air:Determined from make-up air opening table <br /> a la <br /> Cf.
