520 |a"Since the mid 70's, the construction industry has made significant advances in energy conservation and improved indoor conditions. These improvements, however, are shadowed by an increase in building envelope problems to include water penetration, condensation on and in roofs and exterior walls and cladding damages in many of our newer buildings. These problems have been attributed to uncontrolled air leakage. A study of the causes of air leakage through the envelope has revealed that it is not just poor workmanship but a much broader problem, involving inadequate design, the lack of measurable performance indicators, ambiguous regulatory requirements and a general misunderstanding of air and vapour barriers"--Introductory summary.
