Features the latest research on building air tightness from theforemost authorities in the field. 17 peer-reviewed papers dividedinto the following comprehensive categories:

Air Movement, Ventilation and Indoor Air Quality --Building air flows under complex circumstances, primarily largerbuildings with multiple zones, and the challenge of pollutant entryfrom soil gases are presented in five papers.

Window Air Leakage -- Four papers address the airtightness of various window systems. A new ASTM standard formeasuring air leakage at different pressures and temperatures isdescribed in this section.

Envelope Heat and Mass Transfer -- Two papers deal withair flow and moisture in manufactured housing envelopes, and twopapers discuss the interactions between conduction heat flows andair flows in the building envelope.

Envelope and Distribution System Leakage -- Assortedmeasurement techniques are analyzed in three papers and one paperfocuses on field measurement results.
