According to the National Building Code of Finland Section D2 (2012),
ventilation rate should be [greater than or equal to] 6 l/s person (13 cfm/person) in office rooms and [greater than or equal to] 8 l/s person (17 cfm/person) in meeting rooms.
486 mL; p=0.3), or average

1) Maintain building
ventilation rates at or above the minimum rates specified in current codes and standards.
ASHRAE Standard 62.1--2013 contains two alternative procedures to determine mechanical
ventilation rates:
To this effect, the data were clustered in four blocks according to
ventilation rate (V1-V2-V3-V4).
(9) ASHRAE Standard 62.1-2013 requires a minimum classroom
ventilation rate of 15 cfm (7 L/s) (totaled from 10 cfm/student [4.7 L/s per student] and 0.12 cfm/[ft.sup.2] [0.61 L/s x [m.sup.2]]), (2) and an ambient air carbon dioxide concentration level of 400 ppm was assumed for this calculation.
Consequently, a change in the
ventilation rate did not affect the ammonia production rate in the simulations.
Figures 2 through 4 show that, with an increase in environmental temperature, humidity, and
ventilation rate, in a double exponential decay model, the parameters for fast and slow initial transmission rates, [E.sub.01] and [E.sub.02], and attenuation constants, [k.sub.01] and [k.sub.02], would increase when the other experimental conditions remain unchanged.
The larger amount of energy stored and discharged by the solar chimney and consequently a higher
ventilation rate is achieved.
The
ventilation rate in the building was established, operating a variable number of fans for a certain time.
