Ventilation Method
Balanced,HRV(Heat Recovery Ventilator)or ERV(Energy Recovery
Ventilator)—cfm of unit in low must not exceed continuous Low CFM High CFM
ventilation rating by more than 100%.
Directions-Balanced ventilation systems are typically HRV or ERV's.Enter the low and high cfm amounts. Low cfm airflow
must be equal to or greater than the required continuous ventilation rate and 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.) Automatic controls may allow the use of a
larger fan that is operated a percentage of each hour.
Section C
Ventilation Fan Schedule
Description Location Continuous Intermittent
Directions-The ventilation fon schedule should describe what the fan is for, the location,cfm, and whether it is used for
continuous or intermittent ventilation. The fan that is chose for continuous ventilation must be equal to or greater than the
low cfm air rating and less than 100%greater than the continuous rate. (For instance,if the low cfm is 40 cfm, the continuous
ventilation fan must not exceed 80 cfm.) Automatic controls may allow the use of a larger fan that is operated a percentage of
each hour.
Section D
Ventilation Controls
(Describe operation and control of the continuous and intermittent ventilation)
Directions-Describe the operation of the ventilation system. There should be adequate detail for plan reviewers and inspectors to verify
design and installation compliance. Related trades also need adequate detail for placement of controls and proper operation of the building
ventilation. If 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 installed,describe how 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'installation instructions.If the installation instructions require or
recommend the equipment to be interlocked with the air handling equipment for proper operation,such interconnection shall be made and
described.
Section E
Make-up air
Passive (determined from calculations from Table 501.41)
Powered(determined from calculations from Table 501.4.1)
Interlocked with exhaust device(determined from calculation from Table 501.4.1)
Other,describe:
Location of duct or system ventilation make-up air:Determined from make-up air opening table
Cfm Size and type(round,rectangular,flex or rigid)
