What percentage of total heat loss is through air leakage?
I’m looking for modeling or test data that defines the ratio of convective losses to conductive losses. My real goal is to find the tipping point when a leaky building losses more energy via air changes then via the insulated envelope. I’ve had many answers where the losses from air leakage have been as low as 10% or as high as 50%. However, any number has to coincide with a stated leakage in terms of [email protected] or similar. Anyone have access to a study or paper that charts this ratio? Thanks, AL Cobb
