Section A Ventilation Quantity (Determine quantity by using Table R403.5.2 or Equation 11-1) Square feet(Conditioned area including 4389 Total required ventilation 180 Basement—finished or unfinished) 5 Continuous ventilation Number of bedrooms 90 Directions-Determine the total and continuous ventilation rate by either using Table 8403.5.2 or equation 11-1. The table and equation are below Table R403.5.2 Total and Continuous Ventilation Rates in cfm Number of Bedrooms 1 2 3 4 5 6 Conditioned space(in Total/ Total/ Total/ Total/ Total/ Total/ so,ft.) continuou,; continuous continuous continuous continuou,; continuous 1000-1500 60/40 75/40 90/45 105/53 120/60 135/68 1501-2000 70/40 85/43 100/50 115/58 130/65 145/73 2001-2500 80/40 95/48 110/55 125/63 140/70 155/78 2501-3000 90/45 105/53 120/60 135/68 150/75 165/83 3001-3500 100/50 115/58 130/65 145/73 160/80 175/88 3501-4000 110/55 125/63 140/70 155/78 170/85 185/93 4001-4500 120/60 135/68 150/75 165/83 ag0 195/98 4501-5000 130/65 145/73 160/80 175/88 190/95 205/103 5001-5500 140/70 155/78 170/85 185/93 200/100 215/108 5501-6000 150/75 165/83 180/90 195/98 210/105 225/113 Equation 11-1 (0.02 x square feet of conditioned space)+[15 x(number of bedrooms+1)]=Total ventilation rate(cfm) Total ventilation—The mechanical ventilation system shall provide sufficient outdoor air to equal the total ventilation rate average,for each one-hour period according to the above table or equation. For heat recovery ventilators(HRV)and energy recovery ventilators(ERV)the average hourly ventilation capacity must be determined in consideration of any reduction of exhaust or out outdoor air intake,or both,for defrost or other equipment cycling. Continuous ventilation-A minimum of 50 percent of the total ventilation rate, but not less than 40 cfm,shall be provided, on a continuous rate average for each one-hour period.The portion of the mechanical ventilation system intended to be continuous may have automatic cycling controls providing the average flow rate for each hour is met.
