Abstract

The building envelope should be designed to provide a comfortable indoor environment irrespective of changes in the weather. Therefore, to provide a functional and durable building envelope, the dynamic character of the driving forces must be recognized by the envelope designer. The dynamic performance of the building envelope can be evaluated in laboratories in which the design details and most of the dynamic properties of the driving forces are simulated. This paper dis cusses the dynamic processes and the need for dynamic evaluation of structural per formance under wind loading and of rain penetration performance under wind driven rain conditions. Three research facilities are examined for their approach to dynamic evaluation of structural performance and rain penetration performance. Ad ditional information on dynamic evaluation of the building envelope was gathered from standards and the literature. Based on this information, procedures for dynamic evaluation under wind loading and wind driven rain conditions are proposed.
