Calculating Venting Area |
OK, to determine how much ventilation area you need for your house, all you need to know is the square foot area of the attic to be ventilated. Let's use the following simple ranch house for an example.
The house measures 30 feet by 50 feet. There is a 22 foot by 26 foot attached non-heated garage. In reality, the garage doesn't figure into the calculations. That doesn't mean you shouldn't ventilate it, it just means that I will not include it in my calculations:
30 feet X 50 feet = 1,500 square feet
OK. So now we know the square footage of the attic area to be ventilated. Now, let's figure out how much ventilation space we need. Remember, the minimum area requirement when using a gable vent, without soffit venting, is a ratio of 1:150. So, in our example, we will divide the 1,500 square feet by 150.
1,500 square feet / 150 = 10 square feet
See how simple that was! We know we need 10 square feet total of ventilation area.
