Infiltration Values & Calculation
Infiltration losses include both losses through structure construction (e.g. cracks, leaks, etc.) as well as losses due to the normal air changes such as opening of outside doors etc. Note: Calculations are based on average residential values only, adjustments should be made for non-standard situations such as high traffic entrances etc. or for alternate building construction materials and methods. Values listed are for sheltered or partially sheltered to wind exposure. Use next lower value for exposed locations and second story rooms.
