American Society of Heating and Ventilating Engineers Guide, 1935 coefficient of a surface in still air is 1.65 Btu per hour per square foot jw degree Fahrenheit, whereas the average coefficient of an air space in a. outside wall is about 1.10 Btu per hour per square foot per degree Fahrei) heit difference between the two surfaces, at a mean temperature of 4o p An air space coefficient of 1.10 is equivalent to a surface coefficient of 2.20 for each of the two surfaces enclosing the air space, where thj' over-all transmission is computed by using the coefficients of the tvr<> surfaces enclosing the air space instead of the coefficient of the airspa^ itself.
