Niklas W. Vigener, P.E., LEED AP, is a Senior Principal and Group Head with Simpson Gumpertz & Heger Inc. (SGH), a national engineering firm specializing in the design, investigation, and rehabilitation of structures and building enclosures. He has led many of SGHs most notable building technology and historic preservation projects, including the rehabilitation of Yale Universitys Sterling Memorial Library, Columbia Universitys Butler Library, and the multi-phase restoration of the New York State Capitol Building. Mr. Vigener was a lecturer in the Department of Civil Engineering at Johns Hopkins University from 2003  2011. His presentation will describe the important and distinct roles that each barrier plays in building wall design and construction.

Contemporary building enclosures generally consist of layers of light-weight construction materials designed to prevent water  penetration and control condensation, heat flow, and vapor flow.  These layers are material assemblies that serve as four essential barriers - to resist water, heat, air, and vapor flow. The performance of a contemporary building enclosure depends on the proper sequencing, detailing, and constructing of these four barriers.  Barriers must also incorporate design features that enable concealed building materials to dry out and recover from occasional moisture exposure without deterioration or microbial contamination.
