I wonder if anybody else is having the same experience. Isn't the form supposed to calculate Vbz = Rp*Pz + Ra*Az? When I enter the values for the four parameters, the form is calculating a lower value for Vbz. Strange thing is, two weeks ago it was calculating as I expect it to, but now it is calculating differently.
For example
----------------
Rp = 5 cfm / person
Ra = 0.06 cfm / sf
Occ. Density = 36.29 per 1000 sf.
Az = 138 sf
Vbz (2 weeks ago) = 33.32
Vbz (now) = 25.12
Did something change with ventilation rates or is there a bug in the form here?
Thanks.

Omer, are you using the Beta version of the form, or a later version?

This form has always been a non-beta version. Curiosly, I think the calculation mistake has appeared after our other beta forms were updated.

I input the values and I got 33.32, thou I´m a little confuse, according to the formula Vbz = Rp*Pz + Ra*Az wouldn´t the results be:
Vbz = (5*36.29) + (0.06*138)
Vbz = (181,45) + (8,28) = 189,73
