Balanced ventilation systems are typically HRV or ERV's. <br /> Enter the low and high cfm amounts. Low cfm,air flow must be equal to or greater than the required continuous ventilation rate and <br /> less than 100%greater than the continuous rate.(For instance,if the low cfm is 40 cfm,the ventilation fan must not exceed 80 cfm.) <br /> 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 II Location Continuous Intermittent <br /> 7'11.5.1,,:c:, ioa.. Sam- Z4�c 11S <br /> Directions-The ventilation fan schedule should describe what the fan is for,the location,cfm,and whether it is used for continuous <br /> or intermittent ventilation. The fan that is chose for continuous ventilation must be equal to or greater than the low cfm air rating <br /> and less than 100%greater than the continuous rate. (For instance,if the low cfm is 40 cfm,the continuous ventilation fan must not <br /> exceed 80 cfm.) Automatic controls may allow the use of a larger fan that is operated a percentage of each hour. <br /> Section D <br /> Ventilation Controls <br /> (Describe operation and control of the continuous and intermittent ventilation) <br /> V .W - w&,11 Can 470 l5, <br /> Directions-Describe the operation of the ventilation system. There should be adequate detail for plan reviewers and inspectors to verify design and <br /> installation compliance. Related trades also need adequate detail for placement of controls and proper operation of the building ventilation. if <br /> exhaust fans are used for building ventilation,describe the operation and location of any controls,indicators and legends. If an ERV or HRV is to be <br /> installed,describe how it will be installed.If it will be connected and interfaced with the air handling equipment,please describe such connections as <br /> detailed in the manufactures'installation instructions.if the installation instructions require or recommend the equipment to be interlocked with the <br /> air handling equipment for proper operation,such interconnection shall be made and described. <br /> Section E <br /> Make-up air <br /> yeA Passive (determined from calculations from Table 501.3.1) <br /> Imo` Powered(determined from calculations from Table 501.3.1) <br /> Interlocked with exhaust device(determined from calculation from Table 501.3.1) <br /> It_ Other,describe: <br /> Location of duct or system ventilation make-up air:Determined from make-up air opening table <br /> Cfm Size and type(round,rectangular,flex or rigid) <br /> (NR means not required) <br /> Page 2 of 6 <br />
