Section B <br /> Ventilation Method <br /> (Choose either balanced or exhaust only) <br /> �Balanced,HRV(Heat Recovery Ventilator)or ERV(Energy Recov- � Exhaust only <br /> ry Ventilator)-cfm of unit in low must not exceed continuous venti- Continuous fan rating in cim <br /> lation rating by more than 100%. <br /> Low dm: �Q Hig� : Continuous fan rating in cfm(capacity must not exceed <br /> continuous ventilation rating by more than 100%) <br /> Directions- Choose the method of ventilation, balanced or exhaust only. Balonced ventilotion systems are typically HRV or ERV's. <br /> Enter the!ow and hiqh cfm amounts. I.ow c m air flow must be equal to or greater than the required continuous ventilation rate ond <br /> less than 100%greater ihan 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 thai is operated a percentage of each hour. <br /> Section C <br /> Ventilation Fan SchedUle <br /> Description Location Continuous Intermittent <br /> Directions-The ventilotion fan schedule should describe what the fan is for, the location,cfm, and whether it is used for continuous <br /> or interrnittent ventilation. The fan that is chose for con[inuous ventilption must be equal fo or greoter thon Ihe lovr c m air rating <br /> and less thon 100%greoTer thon ihe continuous rofe. (For ins[once, if the low�fm is 40 cfm, the continuous ven[ilotion fon must no[ <br /> exceed 80 cfm.) Automatic controls moy allow the use of a larger fan that is operated a percentage of eoch hour. <br /> Section D <br /> Ventilation Controls <br /> �Oescribe operation and control of the continuous and intermittent ventilation) <br /> �i���-�Q'j� �__ .� - <br /> � ---- <br /> Directions-Describe the operation of the ventilation system. There shou(d be adequote detail for plan reviewers and inspectors to veriJy design and <br /> installotion compliance. Ftelated trades also need odequate detail for placement of controls and proper operation of[he building ventilation. If <br /> exhaust fans are used for building ventilation,describe the operation and location of ony controls,indicators and legends. If an ERV or HRV is to be <br /> installed,describe how it will be installed.!f i[will be conneded ond interfaced with the air handling equipment,please describe such connections as <br /> detoiled in the monufactwes'installation instructions.
