SYSTEM LEVEL VENTILATION RATE ADJUSTMENT
Used for California Title 24 and ASHRAE 62.2. compliance based
on actual, field-measured air flow rates.
Use following procedure to determine adjusted SmartSense sys-
tem level or use simple, fill-in blanks website application at: www.
broan.com, search: smartsense, select model SSQTXE080 or
SSQTXE110, select tab CA Airflow Calculator.
1. Calculate ventilation rate using ASHRAE 62.2 formula 4.1a for
single-family buildings or formula 4.2a for multifamily build-
ings:
Q = (0.01 × A) + [7.5 × (N + 1)] (4.1a);
Q = (0.03 × A) + [7.5 × (N + 1)] (4.2a);
Where:
Q is ventilation rate in cfm;
A is floor area of residence in square-feet;
N is number of bedrooms, but not less than 1.
2. Measure actual air flow (cfm) of each installed fan.
3. Calculated adjustment factor using the following formula:
K = (88 × N
) ÷ [(1.1 × N
TOTAL
Where:
K is adjustment factor (unit less);
CFM
is the lowest air flow of 80 cfm fans measured in step 2;
80
CFM
is the lowest air flow of 110 cfm fans measured in step

N
is number of 80 cfm fans in system;
80
N
is number of 110 cfm fans in system;
110
N
is total number of fans in system (N
TOTAL
4. Calculate adjusted ventilation rate: Q' = Q × K.
5. Set SmartSense master's system level equal to or greater than
Q'.
