%T Calculating Infiltration: Implications for a Construction Quality Standard
%2 LBL-9416
%8 01/1983
%X <p>Extensive work in inf1ltratio~ measurement and modeling has<br />led to a simple method to calculate the leakage area of a<br />house regardless of design or weather conditions. The leakage<br />area, in turn, is used in the LBL infiltration model to<br />calculate infiltration for any ~eather condition. This<br />method, which uses fan pressurization to measure the leakage<br />area, has been used in a survey of over 300 houses located<br />throughout North America. This paper presents the results<br />of that survey and suggests that the present capability in<br />infiltration modeling offers an excellent framework for an<br />air leakage standard ·for residential building. Examples of<br />the interpretation of such a standard are described based on<br />the ventilation rates adopted in ASHRAE Standard 62-1981.<br />The results of the interpretations illustrate differences in<br />structural requirements that will occur when such a standard<br />is applied to several ventilation system designs.</p>
