Predicted and measured air exchange rates
As part of an ongoing indoor air quality (IAQ) modeling study, air exchange rates of ten Kuwait residential buildings were measured according to the American Society for Testing and Materials (ASTM) E741-83 standard which is a tracer gas decay technique. In this study, SF6 was used as the tracer gas. The air exchange rate of a building can not be estimated based on the building's construction or age or from a simple visual inspection. It is possible only when a detailed quantification of the leckage sites and their magnitude area are made. Then the air exchange rate of a building can be calculated in a straightforward manner, given the location and leakage functions for every opening in the building envelope, the wind and stack coefficients over the building envelope, and any mechanical ventilation airflow rates. Although these inputs are normally available, the studies involving experimental verifications are scarce. This means that the reliability of these calculations is unknown. Further, it also uncertain whether these techniques can be used confidently for buildings that may have different physical natures - such as those in Kuwait and the Arabian Peninsula.
