Section B Ventilation Method (Choose either balanced or exhaust onry) � Balanced,HRV(Heat Recovery Ventilator)or ERV(Energy Recovery Exhaust only Ventilator)—dm of unit in low must nat exceed continuous Continuous fan reting in cfm .o Low dm: o� High cfm: �C Q Continuous fan roting i�cfm(capacity must not exceed �� vo continuous ventilation rotiog by more than 100%) Directions-Choose the method of ventilation,bolanced or exhaus[onty.Ba/anced ventilation systems are typically HRV or ERV's. Enfer the low a�high cJm amounts.Low cfm oir flow must be equa/to or greater than the required continuous ventilotion mte 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.J Automatic controls may allow the use of a lorger fan that is operated a percentoge of each hour. Section C Ventilation Fan Schedule Descri tion Location Continuous tntermittent Direttions-The ventilation Jan schedule should destri6e whot the fan is jor,the location,cfm,ond whether it is used jor mntinuous or intermittent ventilation.The fan thot is chose jor contlnuous ventilation must be equo/to or greater than the!ow cfm air ro[ing and less than 100A6 greater thon the mntlnuous rote.(For insronce,if the low cfm is 40 cJm,the continuous ventilation jon must not exceed BO cJm.J Automatic controls may allow the use ojo larger fon that is operated a percentoge of each hour. Section D Ventilation Controls Describe o eration and control of the continuous and interm'Rtent ventilation) ERV has wall coMrol set to 50°k=88 CFM ERV has wali control set to 90%=158 CFM Directions-Describe the operatlon of the veMilation rystem.There should be adequate detall for plan reviewen ond inspedors to verify design and instollation compliance.Related trades also need adequate detail for p/acement of conbols and proper operotion of the 6uilding ventilotion.If exhaust fans are used for building venUlation,describe the operotion and location ojony contro/s,indicaton and legends.If on ERV or HRV is ro be insbolled,describe how it will be installed.If it will be conrreded ond inteijaced with the air handling equipmen4 please describe such mnnections as detalled in the manufattures' installotion instructions.lf the ins[allotion instructions require or recommend the equipment to be interlocked with the air handling equipment for proper opemtion,such interconnectlon shall be mode and described.
