Section B <br /> Ventilation Method <br /> (Choose either balanced or exhaust only) <br /> � � Balanced,HRV(Heat Recovery Ventilator)or ERV(Energy Recovery Exhaust only <br /> Ventilator)—cfm of unit in low must not ezceed continuous Continuous fan rating in cfm <br /> t i t' b o t n <br /> Low cfm: �C High cfm: �no Continuous fan reting in cfm(capacity must not exceed <br /> �� � continuous ventilation rating by more than 100'�6) <br /> Diredions-fhoose the method of ventilation,bolanced or exhoust only.Bolanced ventilation systems are typically HRV or ERV's. <br /> Enfer the low and high cfm amounts.Low cfm air flow must 6e equal to or greater than the required canfinuous ventllation rate and <br /> less than 100%greater thon the continuous rate./For instance,if the low cfm is 40 cfm,the ventilotion fan must noi exceed 80 cfm.) <br /> Au[omatic controls may ollow the use of a lorger fon that is operated a percentage of each hour. <br /> Section C <br /> Ventitation Fan Schedule <br /> Descri tion Location Continuous Intermittent <br /> Direclions-The ventilation fan schedule should describe what the fan is for,the lorntion,cfm,and whether it is used for continuous <br /> ar intermittent ventilotion.The fan that is chose for continuous ventilaiion mus[6e equal to or greater than the low cfm oir rating <br /> and less than 100%greater than the continuous rate.(For lnstance,!f the low cfm k 40 cfm,the continuous ventilotlon fan must not <br /> exceed 80 cfm.J Automatic controls may allow the use of a lorger fan that is operated a percentage of eoch hour. <br /> Sedion D <br /> Ventilation Controls <br /> (Describe operatlon and control of the continuous and Intermittent ventilation) <br /> ERV has wall control-set to 40%=124 CFM <br /> ERV has wall control-set to 70%=217 CFM <br /> Directions-Describe the opemtion of the ven[ilotion system.There should be adequate detail for plan reviewers and inspectars to veriJy design and <br /> installation complionce.Reloted trades also need odequate detail for placement of controls and proper operadon of the building ventilation.lf exhaust fans <br /> are used for 6uilding ventilation,destribe the operation and locaiion of any controls,indicators and legends.If an ERV or HRV is to be installed,descrlbe how <br /> it will be installed.If it will be connected and interfaced with the air handling equipmeni,please describe such connections os dMailed in the manufactures' <br /> lnstallation instructions.If the instollotlon lnstrudions require or recommend the equlpment to be Interlocked wlth the air handling equlpment for proper <br /> operation,such interconnection shall be mode and descrlbed. <br />
