Settiun B <br /> Ventilation Method <br /> ' (Choose efther balanced or exhaust only) <br /> Balanced,HRV(Heat(iecovery Ventilator)or ERV(Energy Exhaust pnly <br /> very Ventflator)—cfm of unit fn low must not eacceed continuous Continuous fan reting M cfm <br /> ventilat3on retlng by more than 10096. <br /> Low cfm; �Z� High cfm: �� Continuous fan rating 1n cfm(capacity must not exceed <br /> conHnuous ventllatlon 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 c m air flow must be equal to or greater thcrn the required continuous <br /> ventilation rate and(ess than 100�greater than the continuous rate, (For instance, if the low cfm!s 40 cfm, the ventilation fan <br /> must not exceed 80 cfm.J Automatic controls may allow the use of a(arger fan that is operated a percentage of each hour. <br /> Section C . <br /> Ventilativn Fan Schedule ' <br /> Description Location Continuous lntermittent <br /> Directions-The ventilatron fan schedule should describe what ihe fan is far, the iocation,cfm,and whether it Is used for <br /> contlnuous or intermittent ventilation. The fan that is chose for continuous vent!lation must be equa!to or greater than the <br /> !ow c m air rating and less than 100%grearer than the continuous rate. (For instance,if the low cfm Is 40 cfm, the continuous <br /> venrilation fan must not exceed 80 cfm,J Automatic controls may pllow the use of a larger fan that is operated a percentage of <br /> each hour, <br /> Section D <br /> Ventilation Controls <br /> Descrlbe operation and control of the continuous and lntermittent ventifatlon) <br /> / s�f <br /> Directlons-Describe the operation of the ventilatlon system. There shauld be adequote detall for plan reviewers and Inspectors to verify <br /> design and instaUation compliance. Related trades also need adequate detail for placement of controls and proper operation of the bullding <br /> ventilarion. If exhaust fans are used for buliding ventilat�an,describe the operation and locatlon of any controls,lndicotors and legends, If <br /> an ERV o�HRV is to be installed,descrlbe how ii will be insta(led.Jf it wi/l be connected andlnterfaced wlth the air handling equipment, <br /> please describe such connections as detailed in the manufactures'lnstallation insirucrions.If the installation instructions require or <br /> recommend the equrpment to be interlocked with the air handling equlpment for proper operatlon,such interconnection shal!be made and <br /> descrlbed. <br /> Section E <br /> Make-up air <br /> Passive (determined from ra{culations from Table 5a13.1) <br /> Powered(determined from calculations from Ta61e 501.3.1) <br /> interiocked wiYh exhaust device(determined from calculation from Tabie 501.3.1) <br /> Other,describe: <br /> LOC8t1011 Of dUCt Of SYSt21'T1 V@f1tl�at1011 t71dkQ-Up dIY; Determined from make-up air opening table <br /> Cfm � � Size and type(round,rectangular,flex or rigid) <br /> (NR means not required) <br /> � G:\Fortns\VentMakupCombAirCaIs041511.docx Page 2 of 6 <br />
