Airflow Performance of Building Envelopes, Components, and Systems

Description Features the latest research on building air tightness from the foremost authorities in the field. 17 peer-reviewed papers divided into the following comprehensive categories: Air Movement, Ventilation and Indoor Air Quality -- Building air flows under complex circumstances, primarily larger buildings with multiple zones, and the challenge of pollutant entry from soil gases are presented in five papers. Window Air Leakage -- Four papers address the air tightness of various window systems. A new ASTM standard for measuring air leakage at different pressures and temperatures is described in this section. Envelope Heat and Mass Transfer -- Two papers deal with air flow and moisture in manufactured housing envelopes, and two papers discuss the interactions between conduction heat flows and air flows in the building envelope. Envelope and Distribution System Leakage -- Assorted measurement techniques are analyzed in three papers and one paper focuses on field measurement results.
