Section B <br /> Ventilation Method <br /> (Choose either balanced or exhaust only) <br /> Balanced,HRV(Heat Recovery Ventilator)or ERV(Energy 0 Exhaust only <br /> ec ery Ventilator)-cfm of unit in low must not exceed continuous Continuous fan rating in cfm <br /> entilation rating by more than 100%. <br /> Low cfm: High cfm: Continuous fan rating in cfm(capacity must not exceed <br /> / z,r continuous ventilation rating by 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 air flow must be equal to or greater than the required continuous <br /> ventilation rate and less than 100%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 <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 rate. (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 o 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 /> ----7/1eti---. ''.;:v.4-4,r '-'/...,---/-, _ <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 detail 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 interfaced 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 /> kj Cfm Size and type(round,rectangular,flex or rigid) <br /> ( R means not required) <br /> i <br /> G:\Forms\VentMakupCombAirCals041511.docx Page 2 of 6 <br />
