The design of high-performance building skins in our cities demands more forethought than building codes or zoning ordinances can anticipate.  This session will define the orders of failures observed in newly-built high-performance skins, correlating them with the four dimensions of space and time, which will be explored through case studies.  We will discuss common myths of building skin design and alternative bid/construction processes that maintain building skin design integrity.


  1. A methodology of categorizing common failures of building skins correlated with 3 dimensional forms of static failures and the dynamic form of failure based on, time, movement and degradation. Develop a matrix of the Four Orders of Failures with key performance requirements to develop comprehensive resilient building skin designs
  2. Review building skin commissioning and construction, from peer review of design and construction documents, shop drawing review, site observations, field post-installation testing to verify building skin performance, and mitigate 1st, 2nd and 3rd Order Failures
  3. Lessons learned from case studies of building skin forensics of historic buildings, regarding 3rd and 4th Order failures.  Review standards for lab and field testing and special conditions requiring modifications to standard protocols. Develop strategies for remediating building skin defects in complex as-built conditions
  4. Discuss smarter bidding alternatives, based on pre-qualification of Contractors, single-source responsibility to promotes prefabricated integrated wall assemblies that save time and improve quality to assure high performance adaptable building skins
