AbstractAs the Integrated Design Process (IDP) approach is beginning to make a difference in theconstruction industry so too is the concept of the Virtual Lab beginning to change the process of evaluating the performance of building systems, specifically envelope systems. This paper elaborates the concept of the virtual lab and provides an example, evaluating the hygrothermal performance of wall systems. The virtual lab could be viewed as one component of the IDP or as a complimentary framework designed to provide information about the performance and durability of wall systems. The impetus behind the development of the Virtual Lab is cost. Performance testing in the laboratory or in the field can be expensive. Assessing durability can be even costlier and results may not be available in a timely fashion. The proposed solution to these difficulties is the judicious combination of computer modelling to predict performance and durability with laboratory testing. The basic framework of the Virtual Lab is presentedhere. Development of the simulation components of the virtual lab, as described in this paper, comprises three stages: (1) development of the model or simulation of a component, assembly or system providing estimates of performance or durability, (2) the laboratory testing providing information on boundary conditions and loading to be used by performance and durability models as well as benchmarking tests to enhance confidence in the simulation results, and (3) the field testing or evaluation to provide further validation of the model, information on boundary conditions, and valuable information on in-service conditions and performance.
