Section B <br /> Ventilation Method <br /> (Choose either balanced or exhaust only) <br /> Balanced,HRV(Heat Recovery Ventilator)or ERV(Energy Recovery n!Exhaust only <br /> Ventilator)—cfm of unit in low must not exceed continuous I I Continuous fan rating in cfm <br /> ventilation rang by more than 100%. <br /> Low cfm: �� 6 High cfm: 18Continuous fan rating in cfm(capacity must not exceed <br /> V 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 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 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 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 /> ERV has wall control set to 30%=93 CFM <br /> ERV has wall control set to 60%=186 CFM <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 exhaust fans <br /> are used for building ventilation,describe the operation and location of any controls,indicators and legends.If an ERV or HRV is to be installed,describe how <br /> it will be installed.If it will be connected and interfaced with the air handling equipment,please describe such connections as detailed in the manufactures' <br /> installation instructions.If the installation instructions require or recommend the equipment to be interlocked with the air handling equipment for proper <br /> operation,such interconnection shall be made and described. <br />
